How To Fix A Hole In A Door

How do you fix a big hole in a door?

Download Article Download Article Hollow core doors are relatively easy to damage, but they’re even easier to fix. Instead of paying for a brand new door and going through the headache of hanging it, simply patch and refinish the damage! In this article, we’ll break down everything you need to know about getting your door back into tiptop shape.

  • Fill in the hole or opening with paper towels, cardboard, or wire mesh, Then, fill the opening in with expandable foam,
  • Scrape the excess foam off, then use auto-body filler or spackle to patch the damage.
  • Once the filler or spackle dries, sand it down. Paint or stain the repair to blend the repair in.
  1. 1 Cut away any loose or broken wood from around the opening. Depending on how the door was damaged, there may be some loose splinters or fragments around the edges of the hole or crack. Rather than trying to repair these loose pieces, use a utility knife to cut away any damaged wood until you’re left with a clean hole that’s mostly free of rough edges.
    • Always cut away from yourself when working with a utility knife, especially when cutting through something sturdy like wood.
    • You may need to make the hole or crack slightly bigger before you can begin repairing it. It’s much easier to repair a larger hole free from damaged wood than it is to repair a smaller one that’s fragmented or broken, though!
  2. 2 Pack the hole with paper towels, cardboard, or wire mesh, These materials won’t make the door stronger or repair it, but they’re an easy and affordable way to hold the insulation foam in place while it dries. Bunch up a few paper towels or whatever material you’re using and stuff them in the hole or crack.
    • The door isn’t actually 100% hollow. There are a series of diamond-shaped pockets inside the door. If your first bunch of material falls inside the door, keep adding more. You’ll eventually fill the section up.


  3. 3 Fill the hole with expanding foam insulation, Expanding insulation foam comes in a spray can with a long nozzle on the top. Point the nozzle inside the hole or crack in your door and begin spraying. The foam will expand to fill the space inside the door, with any excess expanding outside the hole through the face of the door.
    • Don’t worry about the foam flowing out of the hole a bit! You’re going to cut the extra off.
    • Look for the “low expansion” or “low rise” foam if you want something a little easier to work with.
  4. 4 Leave the insulation foam to dry overnight. Once the insulation foam has filled in the hole or crack, it needs to cure all the way through before it can be cut or sanded down. It may start drying in as little as 30 minutes, but it’ll take 24 hours to completely cure.
    • Check the instructions on your own brand of insulation foam for more guidance on how long it will take to dry. Some foams may require longer drying times.
  5. 5 Trim away the excess foam carefully with a utility knife. Position your utility knife slightly above any protruding insulation foam so that it is flush with the face of the door. Gently run the knife down the face of the door to cut away any excess foam. Continue trimming and shaving the foam until you’re flush with the face of the door, or slightly below it.
    • If it gets difficult to trim the foam near the face of the door with your utility knife, switch to a razor blade.
    • Don’t worry if you remove a little too much foam. You’re going to fill it in.
  6. 6 Apply a layer of auto-body filler for a strong repair. Mix the 2 parts of an auto-body filler together on a sheet of cardboard to activate it. Spread the mixture over the hole in your door with a putty knife, Use the edge of a putty knife to smear and press the mixture over the hole, filling in any gaps to make it flush with the door.
    • Auto-body filler is a compound that will give you a very strong door, but it can be quite difficult to work with. It will normally come packaged with a hardening catalyst designed specifically to activate it.
    • Some auto-body fillers do not need to be mixed.
  7. 7 Cover the hole with spackle for a quicker fix. If you don’t have auto-body filler, you can use spackle (joint compound) instead. Use a putty knife to scoop out some spackle and spread it over the hole in your door. Work in long, smooth strokes to smear the spackle over the door as smoothly and evenly as possible.
    • Spackle is readily available, affordable, and very easy to work with. This repair won’t last decades the way auto-body filler will, but this will 100% get the job done.
    • If you don’t have spackle or auto-body filler, you can use wood filler instead.
  8. 8 Wait 24 hours for the surface to completely cure. Spackle and auto-body filler compound start to dry relatively quickly, but both materials take a long time to cure completely. Wait at least one day for the filler or compound to become rock solid if you want the best repair possible.
    • Check the instructions on your spackle or auto-body filler compound for more information on how long it will take to dry.
  9. 9 Sand down the surface of the repair. Buy a set of sandpaper sheets and start around 100- to 120-grit. Begin sanding down your repair compound. Then, work your way up to 220-grit. Sand off the spackle or auto-body filter until it is level with the surface of the door and it looks flat.
    • Repeat this entire process for each hole or crack on the door.

  1. 1 Remove any hardware or hinges if you’re refinishing the entire door. It’s best to paint or stain the entire door to achieve an even finish, rather than only painting or staining the area you repaired. Use a screwdriver to remove the hardware from the door. You might need to remove the doorknob, hinges, or a strike plate near the base of the door.
    • If you only want to paint or stain the repair, that’s totally fine. It may stand out a bit but if it’s not a commonly used door or it’s in an inconspicuous area, that may not be a big deal.
    • If you want to remove the door from its hinges entirely, you can do that as well.
    • Alternatively, you could use painter’s tape to tape off areas you don’t want to paint over.
  2. 2 Find paint or wood stain that matches the color of your door. Choosing the right color of paint or wood stain will make sure that the repaired door matches the rest of the doors in your home. Ask an employee at your local hardware store for some paint or wood stain samples or ask for help in choosing the right paint or choosing the right stain to match the color of your door.
    • If you can, bring in a sample of the door to help match it—such as a piece of the door you cut away when first repairing it.
  3. 3 Apply an even coat of paint or wood stain to the entire door. Use a broad, all-purpose paintbrush or a foam paint roller to apply a single coat of paint or wood stain to the door. Paint or stain any grooves or panels first, then paint long, even strokes over the rest of the door to avoid leaving visible lines.
    • If you’re worried about making a mess, lay down a drop cloth or some old newspaper underneath the door before you begin painting.
  4. 4 Leave the door to dry for 24 hours. Once you’ve applied the first coat, allow the door to dry for 24 hours so that you can see how the color cures into the wood and the repair. Even slight contact with the door can damage the finished look, so make sure everyone who might come in contact with it knows that it is still wet.
    • Check the instructions on your chosen paint or stain for more information on the expected time it takes for it to dry.
  5. 5 Apply a second coat of paint or wood stain if necessary and let it dry. Each coat that you apply to the door will darken the color slightly and improve the look overall. Once the first coat has dried, apply a second coat to help obscure any imperfections visible from the first coat. Leave it to dry for another 24 hours before reinstalling the hardware,
    • Many interior paints and stains will take several days to cure completely. Be careful with your repaired door for 1 week after painting it to avoid damaging your coat of paint.
    • You can apply as many coats of paint or stain as you want, but 2 or 3 coats will normally be plenty to make your door look fantastic.

Can you patch a door hole?

April 2022 – Most average doors in a house or apartment are quite light and even fragile compared to doors with a more massive core. The former have, for the most part, hollow cores that can be damaged very quickly in a moment of carelessness. They say misfortune never rests. Damage to the door is not pleasant look and we usually can not wait long to repair or even buy a new door. If the damage to the door is not too great and we do not need to buy new ones, we can also repair the door ourselves with the help of appropriate tools and means to fill the hole in the door (such as PUR foam).

The best way to repair a damaged door is by filling a hole in the door. This will prevent the door from cracking. The filler will prevent this because it hardens immediately after application. The repair process is quite simple and does not require excessive prior knowledge or skills. This type of repair procedure is similar to repairing holes in a (dry) wall or in other materials.

To repair a hole in the door you need: – Neostik PUR foam UNIVERZAL – Safety gloves – Multi-purpose knife – Sanding paper or orbital sander – Cleaning cloth – Putty knife – Neostik epoxy putty EPOXY KIT – Coating for wooden surfaces – Brush Door repairs can be undertaken without removing the doors from the hinges. However, the repair will be much easier and more accurate if you remove the door anyway and sand it before repairing it and clean the surface with a cloth. Once the surface is cleaned and ready, you can start repairing or filling the hole in the door.

To fill the hole in the door, you will need Neostik PUR foam Univerzal, which allows many applications in construction and electrical installations, in the filling of pipes and other materials. Special formulation provides good adhesion to many coatings. Neostik Pur foam Universal is made from high quality raw materials and additives that provide optimal sound and heat insulation.

If you are dealing with PUR foam for the first time, let us remind you that it tends to cling to materials such as textiles, wood and the like. PUR foam is quite difficult to remove, so be as precise and careful as possible when applying it. We recommend the use of protective gloves when applying PUR foam. Apply PUR foam to the damaged surface or spray it into the hole. PUR foam expands after application and fills the gap inside the door. Once the PUR foam hardens, simply cut it along the surface of the door where some unwanted residue may have remained.

Then apply a filler to the filled surface to smooth the surface of the door. This will make the door surface resistant to additional damage and possible cracks that could occur if the door is not repaired. For this work we recommend the use of epoxy kneading compound Neostik epoxy putty EPOXY KIT, which is used for gluing, repairing and sealing cracks and pipes, quick repairs of pipelines, radiators, tanks, underwater repairs (aquariums, swimming pools), anchoring screws and the like.

The epoxy can be sanded after it dries. The surface thus becomes flat and smooth and blends in with the rest of the door surface. Remove excess epoxy with a suitable knife. You must be careful and try to smooth the surface along the edges. If necessary, you can sand the surface lightly at the end, so that it is not uneven. To make the repair really flawless, you can also apply a wood coating finish to the repaired door, which will nicely fill in the last small visible imperfections and make the damage completely invisible.

Can I fill a hollow door?

Can you fill a hollow door to make it soundproof? Yes, you can fill a hollow door with foam or insulation which would help in reducing the sound transfer but it will not make the door soundproof! Three layers make up hollow-core doors: an air-filled honeycomb interior and two thin veneer or panel exteriors.

The narrow solid space between those layers makes it easy for sound to pass through. As the primary soundproofing option, you can raise the mass of your door as it increases the number of molecules at minimum that sound waves must pass through, resulting in more exertion of soundwave energy exertion and less transfer of noise.

You may add mass to a door by doing a few things as specified below.

Insulation Spray foam: You can fill the door with spray foam to fill the cavity inside the door. You’ll need a few cans of insulation spray foam for this. Drill a few holes in the door, then spray the foam through those holes. Inside the door, the foam will expand and harden over time. Do not forget to wear gloves, as it’s tough to get them off if it sticks to your skin!

S.No. Hollow/Foam Filled Noise Transfer
1. Hollow Door 50-52 db
2. Hollow Door filled with Foam 49-51 db

As you can see from the results spray foam is not very effective at soundproofing, it would reduce a few db but it’s not worth it.

Acoustic Panels : The panels help in reducing the echo by absorbing sounds. A different approach for using acoustic panels would be installing them inside the hollow door. It would take effort and a lot of mechanical work, so I don’t recommend this if you’re not used to DIY projects.

MLV (Mass Loaded Vinyl) Barriers: MLV barriers, composed of salts, microscopic metal particles, and sand, are more environmentally benign than traditional soundproofing materials. MLV barriers are typically supported by drywall and plywood structures. They generally have three layers: two external foam layers that trap airborne noises and reduce reverberation and a core barrier that absorbs impact noises.

Also read: So, can a hollow door be soundproofed? Absolutely. The strategy outlined above will help to lessen the majority of the sound that enters the entryway, and they will, however, always partially eliminate it. This means you must approach the project with realistic expectations to be satisfied with the results.

Can holes in wood be repaired?

Wood putty is a compound used to repair holes in wood. It is available in both a ready-made form and as a powder that must be mixed with water. It has a color similar to that of wood, so it can be used to blend in holes when wood needs to remain visible in a room.

Can you patch up a wooden door?

Repairing a Split/Crack on Painted Wooden Doors – A painted door is probably the easiest to repair as you simply need to fill in the split or crack with the appropriate wood filler, wait for it to harden, sand it down and then re-paint the patch to match the rest of the door. Worst case scenario, you may need to re-paint the entire face of the door so that it matches.

How do you fix a deep scratch on a wooden door?

Fixing a Scratched Door Deeper scratches, however, will require more thorough treatment. To fix more serious scratches, sand off the paint around the damaged area (and a little untouched wood too), and then use a wood filler to mask the deepest scratches. Let the filler dry, and then repaint the door as normal.

How much does it cost to fix a door with a hole?

Holes, Dents, and Dings – Small dents and dings appear on doors from rogue baseballs, enthusiastic dogs, or even the occasional hail storm. If you have a small dent on a wooden door, pick up some wood filler putty for about $15. Larger holes and dents should be left to professionals, especially if you have a solid steel or glass door.

Are door holes standard?

What is Standard Door Prep Standard Door Prep for Door Knobs & Levers: Most interior doors are prepped with a single boor hole. The standard sized bore hole is 2 1/8″ in diameter. Through the edge of the door there is a 1″ cross bore that extends from the edge of the door through the bore hole. (This cross bore is where the latch is installed). In addition to the two cross bores, a door can be prepped for one of 3 different types of latches:


Drive-In Latches: The easiest style to install, as it doesn’t require screws. Simply slide the latch into the 1-inch predrilled cross bore hole and tap into place with a rubber mallet. The ribbed collar around the edge of the latch will hold it securely in place. Radius Corner Latches: Rounded corner faceplate latches are very common. The faceplates give the latch a quality look and hold the latch securely in the door. These faceplates are 2 1/4″ in height and 1″ wide with about an 1/8″ radius on the corners. Many door shops will use a router jig to prep the door for you so that all you have to do is install the latch. Square Corner Latches: Square corner faceplates are the same size as the rounded corner, they just have square corners. If you want faceplates, but your door is prepped for drive in latches you can easily prep your door for these using a 1″ chisel. Just mark the area 1″ wide and 2 1/4″ tall centered on the cross bore and chisel out about 1/8″ depth of material. These square corner faceplates give your door a refined clean look. If your doors are prepped for radius corner faceplates, but you prefer square – just chisel out the very corner.

Standard Door Prep for Tubular Handlesets/ Knob & Lever Deadbolt Combinations: Standard door preparation for a door with both a door knob/lever and a deadbolt or Tubular Handleset have two sets of bore holes and cross bores stacked on top of each other at 5 1/2″ from center to center (like the diagram shown below) It should have the exact preparation for the deadbolt, as the knob below with a 2 1/8″ diameter bore hole and 1″ cross bore. : What is Standard Door Prep

Can you drywall patch a door?

Metal Drywall Patches – Another option is to purchase metal drywall patches that are self-adhesive. These are fine metal meshes. The mesh can be cut so that it is just a little larger than the hole in the door. The patch is applied and allowed to cure. The patch will create a good base for a final coat of wood putty.

Can you use wood filler on hollow door?

Instructions –

Repair splinters and cracks: It’s not uncommon on hollow core doors for the bottom of the door to start to splinter off and leave some uneven surfaces. The best way to repair that is to get some wood filler and a putty knife to fill the splintered areas. Put a layer of wood filler that’s a little higher than the surface of the door so you can sand it down to a level surface once the wood filler has dried. Paint the door: The color and tone of the wood on hollow core door is always a dead giveaway that it’s a cheap door, so painting it helps to hide those splintered areas you just repaired and makes it look like it could be a solid slab door. I like to sand down the door lightly with a medium sandpaper to rough up the surface and then do a coat or two of a stain-blocking primer to keep the wood stains from bleeding through (if painting the doors a dark color, you can probably get away with a paint/primer in one rather than separate coats). Then use a semi-gloss paint in the color of your choice (I usually do white) to refresh your door with a low nap roller for smooth surfaces. Replace the hinges: A lot of the time, an older hollow core door will also have older hinges that could use a swap for something nicer and newer. Our doors had really clunky heavy hinges that are meant for outdoor doors (very heavy duty) and they were also rusty and splattered with several colors of previous trim paint colors. Getting a pack of sleek modern hinges can go a long way in modernizing a door and making the whole thing feel refreshed (you’ll want these if your hinge cutouts are rounded). Switch the door hardware: Now this is the final step in making your door makeover a real success! Getting some sleek modern door hardware will be a giant leap forward for your hollow core door project. I wanted to spend a little more on the hardware to really make the end result feel more luxe (and since we saved so much on rehabbing the doors that was possible), so I bought this one that has a 5-year finish warranty for the finish color I wanted (a nice thing to have for brass hardware) and here’s a pretty budget-friendly option too, If you are wanting to save all around, they have more budget-friendly options that are similar like these and these that would be beautiful too! Add some custom trim: Now that you have a repaired door with a fresh coat of paint and new hardware, you can call it a day and admire your new door, OR, you can go one step further and make the door pretty special with some custom trim additions. I’ve made quite a few basic doors feel much more special with either wooden trim or wooden cutout designs, but in this house I added an arched half-round trim design to the back and all the main interior doors with flexible moulding and I just LOVE how it made the doors feel so much more luxe and custom.

Can I fill a hollow door with spray foam?

Fill a hollow core door with insulation foam – This option is not frequently discussed, but you can turn a hollow core door into solid by filling it with insulation foam. Make small holes on the edges of the door. Start from a low point on the door and let the foam expand and solidify.

  • Eep progressing to the top of the door, spraying foam every 12 inches.
  • Plug the holes using tape so the foam doesn’t release outward.
  • Remove the lock mechanism during the treatment to avoid damaging the hardware.

How do you know if a door is hollow or solid?

What Are Solid Core Doors? – It’s impossible to tell just by looking at a door whether it has a solid or hollow core. Both construction types are available in a variety of attractive designs to complement any style of home. Inside, Masonite solid core doors are constructed with 70 percent more sound-dampening material than our standard hollow doors. This offers many important benefits:

Sound Dampening: The thicker, denser material of solid core doors deadens sound more effectively, so you can focus on work or rest and relaxation. Weight: Solid core doors feel more substantial than hollow core doors when you open or close them, and they have a solid sound when you knock on them.

Durability: The heavier weight of solid core doors also makes them more durable than hollow core doors. They can better withstand all of life’s bumps and bruises. They’re also more resistant to expansion and contraction than traditional wood doors, making them a better choice for hot and humid areas like the bathroom. Value: Solid core doors are more affordable than solid wood doors. And, once all their advantages are considered, they can offer better value than hollow core doors.

What can I use to fill a hole in UPVC door?

If so you want the best filler that most closely matches the finish of the door. Upvc is difficult to get something to match the finish of with a filler, I’d say your best bet would be decorators caulk or general purpose filler. It will be messy and go everywhere but should do what you need. Hope that’s helpful!

What can I use to fill screw holes in metal door?

Supplies Needed: –

  • Bondo
  • Bondo spreader
  • Mixing surface (I use scrap cardboard so I can throw it away)
  • Something to mix with (I use small scrap wood or plastic cutlery)
  • Primer

To repair the holes, I’m using one of my favorite DIY products, Bondo. In the past, I’ve used it for filling holes in furniture, but it’s perfect for this too! If you’ve never used Bondo, it’s a bit messy and stinky, but it’s pretty easy to use. Bondo is a 2-part compound that you mix and apply.
