Frequently Asked Questions

Do you use wood filler or replace the wood?

For minor surface damage, we use high-performance epoxy wood fillers. However, if the structural integrity of the sill is compromised, we cut out the rotted section and splice in new treated wood or replace the entire sill for a permanent fix.

Can you wrap old sills in aluminum?

Yes. After repairing the rot, we can install custom-bent aluminum capping (cladding) over the exterior frames and sills. This provides a maintenance-free finish that never needs painting and protects the wood from weather.

Will the repair match my existing trim?

We strive for a seamless look. We select wood species or composite materials that match the dimensions and profile of your existing trim, leaving the repair sanded, primed, and ready for paint.

Why is a Technical Visit necessary?

Wood rot is often like an iceberg; what you see on the surface is only a small part of the problem. Water intrusion can travel inside the wall, affecting the structural studs and insulation. Our Window Frame & Sill Repair assessment involves probing the wood to determine the depth of the decay and identifying the leak source (like missing drip caps) to prevent recurrence.
