What Is Dry Rot
While wet rot requires a significant water source to grow and create damage, dry rot is more resilient. Dry rot can go undetected for long periods of time because theres often very little indication of its development until major damage has occurred.
Dry rot is caused primarily by the fungus Serpula lacrymans coming into contact with unsealed wood that has a moisture content of around 20-30%. This level of moisture can be caused by small leaks, poor ventilation, or humid climates.
Creating A Wood Patch
Step 1 Use a Japanese hand saw to cut the wood smoothly and straight.
Step 2 Cut a piece of cedar to the size of the hole you want to fill.
Step 3 Wet the exposed wood with a damp cloth
Step 4 Apply polyurethane glue to the wood and place the patch
Step 5 Drill two screws on each side of the patch to hold the patch in place
Step 6 Remove excess glue from the patch after 6 hours
Proper Rotten Wood Repair By Professional Contractors
Correct methods to repair rotten wood begin with assessing the damage to decide which parts of the wood need to be repaired or replaced. Missing a single piece of rotten wood may harm the rest of the structure depending on the core reasons for the initial rot. Proper wood selection and preparation is essential to make sure the repair matches the current carpentry, thereby maintaining the overall appearance of the property. Properly prepping and sealing the wood will ensure that the repaired pieces are long-lasting.
Working with the professionals at CertaPro Painters® always helps to ensure that your commercial exterior wood surfaces are properly repaired and sealed with the correct products.

Can I Repair Rotted Timber
The answer is yes, maybe. Theres generally something that can be done to rid your home of rotten timber, but whether it can be repaired or needs to be replaced entirely depends on the level of decomposition.
If the timber is soft to the touch, crumbling apart, or has fungi sprouting out of it, its beyond saving. All the rotten parts will need to be removed and replaced. It might not be necessary to remove the entire piece, though. If only part of the piece is affected, it may be possible to remove just the rotted parts and fill the holes with epoxy or polyester filler.
If the timber is in the beginning stages of rotyou might see some discoloration, but its not soft or crumblyit may be possible to apply a fairly simple treatment to stop it from spreading.
But, before you run out to the hardware store, be aware that theres some potential pitfalls to amateur repair. When youre not experienced in finding and eliminating rot-causing fungus, its easy to miss patches or fail to treat them properly, meaning that all your hard work will be in vain and your home will continue to be damaged.
It can actually end up costing you more than a professional handyman, if youre not being thorough enough or you accidentally damage your home attempting your own repairs. Youll also need to purchase tools and repair materials if you dont already have them.
Remove The Rotten Part Of The Wood
Step 1 Scratch the rotten wood and dig up loose rot using a claw hammer. Place the hammer claws at the root of the rot. Apply pressure when pulling the nail back toward you. Remove as much rotten wood as possible without causing any damage to the good wood. Simply remove the soft and rotten wood only.
Step 2 Remove the remaining rotten wood using a router with a V-shaped bit and hold it while keeping the drill bit 3.2 mm or 18 inch from the woods back edge. Use short back and forth movements to remove rot that the hammer did not reach. Keep grinding the wood until you have a healthy, solid wood because any it of rotting is left behind, it will cause damage again. Hardwood is more difficult for routers to cut. Wooden beam.
Step 3 Remove the paint and surface rot as several touch-up solutions do not adhere to existing paint and must be removed. Use a paint scraper or coarse 60 grit sandpaper to remove any residue or dirt, rust, or primer on the wood surface. Apply equivalent pressure when working in a circular motion.
Step 4 Apply 4-6 coats of wood repair agent to the area. Use the included brush to paint the entire surface of the restorer. Work the restoration between layers for 2 minutes so that it can be immersed in the wood. Allow the repair agent to dry completely for 2 hours before retreating. When using the repair agent, wear rubber gloves to avoid contact with the skin.

How To Recognize Dry Rot
Dry rot is the cause of the most frequent issues that arise with lumber in homes. It is wise to inspect your home once a year to detect any weaknesses in the wood. It is important when examining the wood that you look for soft or damp wood that also has a look of decay.
Once you have uncovered an area that you think may be infected, use a screwdriver to poke the wood. If the timber in the poked area feels soft, then you may have discovered dry rot. It is recommended to hire professionals who can check for rotting wood, and they will also be equipped to fix wood rot before it becomes a larger problem.
Diy Vs Professional Assistance
There are a few things you can do to try and fix the damage yourself, but in some cases it may be necessary to call in a professional.
If the rot has only affected a small area, you may be able to cut away the rotted or damaged wood and treat any remaining healthy wood. If the rot has spread, however, youll need to remove all traces of it and rebuild the damaged area, which may require professional assistance.
Whatever you decide, make sure you act immediately as wood rot tends to spread quickly and become a real problem if not treated.

Apply A Wood Preservative To Minor Damage
If youve caught the decay early on and the timber is only discolored, not soft or crumbly, try applying a wood preservative product that contains copper or borate. Follow the manufacturers instructions carefully. For the white variant, that may be sufficient to stop the fungi from spreading but youll need to monitor the treated area because itll be susceptible to future fungal infestations.
When youre dealing with brown rot, make sure to treat the wood with fungicide and sterilize any surrounding materials with a biocide, because brown rot is capable of traveling on or through materials like brickwork and plaster.

How To Easily Repair Rotten Wood :
I was surprised at how easy it is to repair and clean up rotten wood. All three of our outdoor gates were in major need of some wood repair.
First, I used a scraper to remove all the old rotten wood from our gates. It easily fell out, so this was a simple task.
Next, I used Mirwax Wood Hardener to secure all the remaining wood in the open gapping area. I applied it with a disposable sponge brush until the wood had a shiny finish.
One the wood appears shiny, its time for it to dry. Allow to dry for 2 to 4 hours.
After you wait the allotted time, you apply Mirwax wood filler. Using a plastic spreader, apply the filler and spread it smoothly across the wood. Sand as needed.
You can see the wood filler below in the orange/wood color. Its difficult to tell from the photo, but it has been sanded smooth to the touch. I started playing around with paint colors, gray or blue.
And our front screen door got a little wood repair and paint job, too.
After you have repaired your wood rot issues, its time to give those gates and front doors a new coat of paint. Check out how I went from raspberry red to a soft moody blue!

Patching Or Replacing Rotted Wood
When it comes to repairing wood rot, you can either repair the wood by applying a strengthening or filler to the damaged wood or remove the rotted wood and completely replace it. How do you decide?
Consider the following when deciding to repair wood rot:
- How large is the rotted area? If its a small area, repairing might be easier.
- Is it historical? When you have historical elements, either in style or building materials, it might be better to take the time to repair and make sure the historical significance is not lost.
- How hard is it to replace? Window sills are something that is typically easier to repair than replace. They are more difficult to remove and reaching the area to repair is often fairly simple.
When should you replace the wood:
- Is it structurally important? Repairing wood is not going to give the same strength as a new piece of wood. Replace that wood if it is any way important to the structure.
- What will it look like after? If the repair cannot be covered up, then it should be replaced. For example, a beautiful stained piece of wood might be better off completely being replaced because you would see that patching under the stain.
- Is the wood replaceable? Headers, footers or other building materials are easily replaced with lumber yard wood. Replacing the damage with a 1 foot 2×4 is a fairly straight forward project. Trying to match a specialty wood might be harder.
