Wood Rot Repair in Boston & South Shore Areas
The Boston and South Shore areas are notorious for their Colonials and Cape-style homes with exteriors made of wood. Most South Shore clapboards and trim are made of wood, and some South Shore homes even have cedar roofs and wooden gutters!
While wood exteriors offer a classic look, our cold and wet winters combined with the salt air cause wood rot to be an issue on the South Shore.
Signs of Rotting Wood on your South Shore area home:
We see wood rotting in areas of high moisture first: trim, sills, and areas close to the ground are target areas for rotting wood. Of course, if a tiny bit of rot is ignored, it becomes a bigger problem.
This is a classic case of “a stitch in time saves nine.” We have carpenters on staff to replace the rotted wood before painting. About 1/3 of the homes we paint need some wood replaced beforehand – something we’re used to handling.
We have carpenters on staff, so our busy Clients don’t have to hire a separate carpentry company before we paint for them.
Trim board options for your home’s exterior
Many South Shore/Plymouth area customers replace their trim with PVC trim (such as Azek). While PVC trim is more expensive than wood trim, it does not rot or decay and does not expand and contract as much as wood.
The good news is that while PVC material is more expensive than wood, the labor to install it is about the same.
Most of the time, some of your wood trim will not be rotted at all and won’t rot for years. Wood trim is most vulnerable to rotting in areas of high moisture (like toward the ground).
In most cases, we replace only the rotted trim boards with PVC and leave the wood in good shape in place.
And since PVC is 100% paintable and looks just like wood trim. This way, when we splice in a few PVC trim boards to your otherwise wood-trimmed home, the PVC blends right in once it’s painted, and you can’t tell the difference between the wood and PVC trim on the home.
We can even use PVC trim boards in historical profiles, so you get PVC’s durability while keeping your home looking historically authentic.
What about the cost to replace trim with PVC vs. Trim?
The PVC boards will slightly more expensive in the short term, but since the labor is the same as installing wood, you’ll save money and hassle in the long run by never having to replace those trim boards again.
Preventing exterior wood rot on your home.
Especially in the Northeast, the exterior wood on your home needs serious protection from wood rot. Houses may experience structural damage if wood rot is left unchecked. Fortunately, there are a few ways to prevent wood rot – let’s dig in:
Why does exterior wood rot?
Wood rot is a form of decay triggered by moisture. For example, in the Boston area, water may puddle on your deck floorboards and take a day to dry after a rainstorm. Or your exterior trim near the ground might soak up moisture and take a while to dry out. When this happens, microscopic organisms that can get inside the wood can cause it to rot. This, in turn, weakens the fibers of the wood and causes the integrity of the wood to be compromised.
If you already have wood rot on your home’s exterior, you must replace the wood in those spots. Nonetheless, it cannot be stressed enough – if the wood on your home’s exterior is rotted, you cannot paint over it to “fix” the rot. If you paint over wood rot, the paint will peel, and more moisture will seep into the wood.
“What parts of my exterior are most vulnerable to wood rot?”
Most of the time, moisture gets into cracks in the wood and underneath cracked or peeling paint. The photo below gives you a sense of many vulnerable areas for wood rot on your home’s exterior:
“How many sides of the wood should I paint when installing new wood?”
Prime all 6-sides of the board – even the cuts – the primer will help keep moisture out and prolong the longevity of the wood.
If you’re installing a new wood deck, staining the underside is not a common practice, but it will help protect the wood.
Is pressure-treated wood less prone to wood rot?
Yes. Pressure-treated wood undergoes a chemical process in a pressure chamber to make it more durable and less prone to decay.
As a result, decks, fences, floating docks, and other structures are prime uses of pressure-treated wood in Massachusetts.
Should I install a wooden deck or use synthetic wood like Trex?
As much as we’d like to paint your deck year after year, we recommend synthetic woods like Trex because:
While more expensive to install, Trex decks need no ongoing staining.
Wood decks – especially Mahogany decks – need to be stained every year to keep them looking great and protected. The minute you stain them, the clock starts ticking, and the foot traffic, hot sun, and water puddling fade the stain, so the next summer, it needs to be restained. Staining a deck is usually $1,000+ and requires time that we just don’t think you need to spend. Go with Trex.

Applying caulk to prevent wood rot
To prevent wood rot, seal all cracks in the wood and around exterior doors and windows with a latex exterior caulk.
If you notice dry, old, hardened caulk in the gaps or seams, dig or scrape it out as best you can before applying a bead of new caulk.
How do paint and stain prevent wood rot?
Your home’s wooden exterior is painted or stained to help protect the wood and keep the moisture out.
Stains penetrate the wood while paints sit on the wood’s surface.
