Your home's wood trim probably has wood rot. The rot will be obvious, hidden, or covered with paint. Rotted wood must be repaired or replaced to prevent water, air, and bug infiltration.
Wet or dry rot can affect any home's wood. A rotten wooden door, floorboard, trim, window sill, or column may signal serious problems. Rot spreads quickly if not treated as a fungal infestation. Replacing damaged wood is a hassle and can be expensive, but there's good news. Non-structural woodwork rarely needs replacement. Use easy-to-use products to strengthen the weakened area. How-to:

What products are out there?
There are two fundamental categories of products that are frequently utilised in the process of filling holes in wood. These categories are wood filler-type products and wood restoration products or kits. There are several different brands of each category.
Wood fillers are products like Bondo and Minwax that are designed to be multi-purpose fillers for wood that has gaps, holes, or has rotted. Examples of wood fillers include: They have a straightforward application process, a rapid curing time, and there is no indication that they will contract once they are dry. However, they will contract slightly and may begin to pull away from the edges of the wood, particularly in applications that place them in the outdoors where they are subjected to the varying conditions of the climate.
These kinds of products are common for a wide range of applications, but the results they produce aren't always perfect or particularly long-lasting. However, they do have a purpose; for example, they can be put to use to make quick fixes that are only intended to be temporary, and they are fantastic for performing simple tasks such as filling nail holes and other similar activities.
The bigger the projector and the more serious you are about a professional-looking finish, the better a wood restoration product or kit is. CSHardware recommends Abatron's wood restoration kit. These work for any wood-filling project (although filling nail holes with the stuff would be overkill). You can use it to repair damaged floorboards, wooden columns, or logs. These products are often used to repair rotted window sashes.
How to Check for Rotted Wood
Consider walking around your house a few times a year and inspecting the wood for rot.
- Look at the edges of the trim, especially where it meets the roofline or meets the ground.
- Look at window sills and other wood components that lay flat and allow water to settle on them.
- If you are unsure if an area is rotted, then gently push on the area with a small screwdriver; if it sinks in and the wood is soft, it's rotted.
Ok, so you've got rot! Let's talk about why it happened, what can be done to prevent it and options for repairs.
What Causes Wood Rot?
First, wood rot occurs for a couple of reasons but mainly due to the quality of the wood used and the installation method.
Most tract homes over the past twenty-five years used "finger-jointed" pine wood as the trim. This low-quality trim usually fails in a few years. Finger-jointed wood is a trim made from short, glued-together wood pieces. The wood is then machined and primed and looks great the first day it's installed.
When the wood gets wet (mostly the end grain) or the paint coating fails, the end-grain finger joints quickly soak up moisture and rot the wood. Force-grown pine trees produce pinewood that is softer and less dense than normal wood. Old-growth pine wood is denser and more durable than fast-grown species.
Improper installation methods, such as not priming or painting the wood's back and ends, also cause rot. I can't tell you how many homes I investigate and price a paint job for that have all of the ends of the trim wood exposed to the elements and unpainted. These ends soak up house and air moisture and start rotting.
If trim wood is installed on a roof without end grain sealing, guess what? Roof water will rot trim wood.
Same for wood on the ground or against masonry or stone. Masonry is porous, like a sponge: it soaks up water and transfers it to wood, which fails.
How to Fix Rotten Wood on a Roof
Whether you are repairing a small section of your roof or replacing the entire roof, fixing rotten sections of the roof decking, also known as the sheathing, is essential to creating a sound structure that is watertight. Roof decking, which is secured to the trusses of the roof using nails, not only serves to hold roofing materials such as felt paper and shingles, but it also helps to protect the structure of your home from the wind and makes it more rigid. Changing out the rotten roof boards can help protect the structural integrity of your home and protect it from water damage that may be caused by leaks.

Locate Dry Rot Roof Damage
If you are only going to replace the section of the roof that is damaged, you need to determine the scope of the damage as well as the specific location of it. Check to see if there are any cracks or holes in the interior of your home. When it has been raining, check the ceilings, attics, and crawl spaces of the home for discoloured drywall or wood.
In order to identify the location of water stains on the underside of the roof decking, it may be necessary to remove the drywall and insulation. After the shingles and underlayment have been removed from the roof during a re-roofing project, the decking should be inspected. Use a hammer to test the stability of the water-stained sections by tapping on them.
Remove the Shingles
Remove the shingles that are located around the damaged area. In most cases, eight nails are used to secure each shingle; four are driven through the middle of the shingle just above the tabs, and the remaining four are driven through the shingle that is directly above it. To remove the felt paper from beneath the shingles, pull it up.
As you make your way up to the roof, expose all of the wood that has rotted. By carefully removing the second set of four nails, you can maintain the integrity of the subsequent course of shingles. During the process of re-roofing, begin at the highest point of the roof and work your way down, prying up the shingles with a pitchfork as you go. Remove all of the shingles.
Remove the Rotten Wood
When replacing roof decking, you first need to get rid of the old, rotten section. You may need to cut a little extra to expose enough of the trusses and make sure you get rid of all the rotten wood. Your circular saw's depth setting should be adjusted to match the thickness of the roof decking. Remove the damaged tissue completely.
Use a claw hammer or a pry bar to pry out the nails, and then remove the piece that was cut off. You will need to uncover at least two trusses in order to secure the replacement section with the replacement wood by nailing it to the exposed trusses. If it is at all possible, you should keep the section that was cut out in one piece so that you can easily measure and cut the piece that will replace it.
Replace the Roof Decking
Choose a thickness of plywood or oriented strand board that corresponds to the profile of the wood that is being replaced. Take some measurements of the section that was cut out, assuming you were able to keep it in one piece. If this is not the case, you will need to climb up onto the roof and take measurements of the opening so that you can cut the replacement piece to be an exact match.
Orient a piece of the replacement material so that its grain runs perpendicular to the roof trusses, and cut it to the dimension of the opening. Insert the piece that has been cut into the opening, and then secure it to the trusses using nails that are spaced every 4 to 6 inches.
Replace Underlayment and Shingles
After repairing the plywood roof hole, seal the seams and re-roof. Bitumen tape the deck's seams. Overlap felt paper to cover the roof. Staple or nail it to the roof decking.
Replace the removed shingles. Under the top course, slide new shingles. First nail it through its centre, then through the one above it. Repeat the pattern until the repair is complete.
Fixing rotted wood on your roof prevents leaks and further damage. Whether you replace the whole roof or a section, you extend its life.
Wood Rot Prevention
Wood should be:
- Decoupled from the masonry with flashing or with an air gap and never rest on the masonry or the ground.
- Primed and painted on all six sides prior to installation.
That's right, the paint should go all the way through to the other side of the wood. In the event that it is not, the water and moisture from the house will seep into the wood through both the front and the back of the structure. You might be familiar with the concept known as "back-priming," which describes the process by which the component is primed on the backside before it is installed.
Another method for preventing wood rot is performing routine preventative maintenance on the structure. In New Jersey, depending on the condition of the wood trim, it should be cleaned, caulked, and repainted anywhere from every three years to every seven years. If the wood is not painted on a regular basis, the paint will eventually flake off, leaving the wood without any kind of protection from the elements; it will also be more likely to absorb water. If it is not painted on a regular basis, you have the option of "paying me now or paying me a lot more later."
Repairing Rotted Wood
You primed the back of the wood trim, painted it on all six sides, kept it away from masonry and roof surfaces, and painted it every five years, right? Ok, good job! It ought to hold up. In New Jersey's harsh and wet environment, even the best maintenance plan will sometimes result in rotted wood. Unfortunately. Let's have a conversation about the possibilities for making quick repairs, general repairs, and long-term fixes for rotten wood.
The Quick Fix
Dig out the rotted section, let it dry, then fill it with epoxy, prime, and paint it. This repair is good if you're trying to save money or the rotted area is hard to replace (and when the rotted area is dry enough to accept the filler). Wood filler is another option. Even exterior wood filler is porous and fails in a year, so use epoxy.
Pine is used for general repairs. Finger-jointed is worst, clear pine is best. Clear pine is knot-free. You could remove rotten wood, prime, paint, and instal a new piece. (It'll probably rot again.)
Permanent Wood Rot Solution
It is possible to make a repair that is not only functional but also long-lasting by removing the entire section of wooden trim and then installing a section of trim that is manufactured. The majority of man-made trim is made of PVC, which can be shaped and installed in the same manner as wood. One brand of PVC trim is called Azek. PVC does not need to be painted, but it looks significantly better when it is first caulked, then filled, and then painted white or another trim colour.
Boral For Trim
Boral brand trim is yet another type of material that is permanent. This material is brown in colour and is suitable for painting with darker colours such as Tudor Brown. Boral is a material that is made up of partially recycled poly-ash, it is simple to instal, and it takes paint very well. When it comes to top coating these alternative trim products, the best option is typically a premium lifetime paint such as Sherwin-Williams Duration.
If you are looking for a solution that does not involve the use of any plastic on the house, then you should think about replacing failed areas of wood with cedar trim wood. Cedar does not decay easily and will serve its owner well for a very long time if it is installed and cared for in the correct manner.
Wouldn't it be nice if, in the United States, the standard was to build homes to last hundreds of years, rather than just twenty, thirty, or forty years, before having to start stripping off cheap finger-jointed trim and/or cheap siding? Those are the numbers that are typically used. Why our building codes even permit such subpar products to be sold is beyond my comprehension.
What You Should Know About PVC
PVC, another material that appears to be a permanent solution, has been on the market for a relatively short period of time, and there is a possibility that it, too, will not be permanent. Ozone and ultraviolet rays could cause it to deteriorate. If it is installed too tightly or with the wrong fasteners, PVC has the potential to warp, twist, and move when subjected to significant temperature changes. If you decide to go the route of using high-quality materials, you should make sure that you invest in a skilled contractor as well so that you can receive sound advice and installation.
How to Repair Rotten Wood Without Removal
If the damage is caught early enough, removing the rotten wood and using an epoxy filler strengthens the damaged area. Once the wood is repaired, take the necessary precautions to ensure more moisture cannot cause further damage.
- Place a wood chisel near one end of the damaged area. Use a hammer to tap the chisel's back end and push it through the rotten wood, removing it. Continue hammering the chisel through until as much of the rotten wood as possible has been removed.
- Rub a wire brush over the damaged area to remove any loose wood pieces. Drill shallow holes into the damaged area using a one-quarter-inch drill bit. Space the holes approximately 1 inch apart.
- Mix a liquid wood epoxy according to the manufacturer's directions. Pour the liquid into a squeeze bottle. Apply the liquid to the damaged area and squeeze it into the holes you drilled in Step 2. Use a small paintbrush to spread the mixture over the damaged area's entire surface. Continue to apply the liquid wood epoxy until the area is fully saturated.
- Mix a wood epoxy according to the manufacturer's directions. Scoop a small amount of the mixture up with a putty knife. Use the putty knife to apply the mixture to the damaged area. Press the mixture firmly in place, so it gets into all the gaps and adheres to the surface.
- Use either the putty knife, a small strip of wood or your gloved fingers to smooth and shape the wood epoxy to closely match the damaged area's surrounding surface. It does not have to be perfect at this point. Allow the epoxy to dry for approximately 4 hours.
- File down any ridges in the epoxy with a rasp or piece of 80-grit sandpaper. Try to get it to match the surrounding area as closely as possible. If you sand away too much epoxy, mix a little more following the manufacturer's directions and apply it.
- Smooth out the repaired surface with 120-grit sandpaper. Use a paintbrush to apply a coat of alkyd primer to the epoxy and surrounding area. Allow the primer to dry before painting fully.

FAQs About Wood Rot
Some find painting rotten wood a quick and easy fix. However, it only hides the rot and makes the wood visually appealing. It ignores the underlying causes that can lead to severe issues down the line. Painting does not stop wood deterioration; it simply delays the process of the wood falling apart.
The common type of wood rot you may encounter and what is often confused with termite damage is dry rot. Dry rot is caused by fungi that attack wood and destroys its interior structure, hollowing it out from the inside.
'Dry rot' is an 18th-century term that generally described what is now called brown rot. The term was used because the damage was present in cured or dried timber of ships and buildings and was thought to be caused by internal 'fermentations' rather than water.
Sand the damaged area with medium-grit sandpaper, following the direction of the wood grain. The goals are to smooth the wood, remove loose paint, and prepare the surface for accepting new primer and paint.
Can Rotten Wood Be Repaired? Rotting wood can be repaired by first removing any rot from the original board or beam of wood. Once that has been done, you can fill the area with a wood-patch or polyester filler. This material will fill the area and harden to provide strength and durability.
