When Replacement Windows Aren’t in the Budget

By Matt Weber

Wood rot is caused by a type of fungus that destroys wood. It is as damaging as termite or other insect infestation, and can wreak havoc on wooden windows. If the windows aren’t maintained with paint, caulk and glazing, then wood rot can take hold and completely ruin the casing.

However, in some cases you can catch the rot and make repairs before a complete window replacement is necessary. We’ll take a look at three options for making spot repairs on partially rotted windows. (Note that these fixes are intended for painted windows and not stained wood).

Durham’s Water Putty

Durham’s Water Putty is a powder product that is mixed with water on site and can be used to repair damaged wood if applied properly. The putty is also easy to use and easy to clean up. You also get a lot of product for your money.

Mix the Water Putty to the consistency of thick pancake batter.

First, remove all damaged material and wood rot with a screwdriver, chisel, shop-vac, etc. In a mixing container, add a little water at a time to the powder and stir with a paint stick until you achieve a consistency similar to thick pancake batter.  Apply the product in layers up 1/4-in. thick at a time. Allow each application to dry before adding more product. Once the damaged area has been completely filled and dried, sand the area smooth. It is important to finish the repair by sealing it with a waterproofing product such as exterior primer and paint.

Apply the Putty in ¼” coats, allowing the product to dry between applications

For a belt-and-suspenders approach, apply a thin coat of Gorilla Glue over the repair before painting to help seal out moisture. Visit www.waterputty.com.

Build up coats of Water Putty until the damaged area is filled just above the surface. Once dry, it can be sanded, primed and painted.

PL FIX 2-part Wood Repair

PL FIX is a two-part poly-urethane-based wood repair filler from Henkel Consumer Adhesives Inc. The resin and hardener are mixed together to create a light tan epoxy. The filler is thin enough to fit into small gaps and cracks, but thick enough that you can mold it. And unlike some other wood fillers, it doesn’t shrink or crack. The down side to the PL FIX is that it’s very sticky, which makes it tricky to work with and difficult to clean up. However, the up side is that the material can be molded into a three-dimensional wood replacement that can be cut or routed into shape. If you need to replace a damaged sill corner or chipped molding profile, you can form the repair from PL FIX and cut the final shape once it’s dry. Visit www.loctiteproducts.com.

The PL FIX product can be cut and shaped to match existing wood profiles.
