I recently hired a contractor to replace a french door due to water issues. It turned out to be a mistake, because when we found out there was a flashing issue, they would not guarantee their repair against future water leaks.
"We install doors and windows, we won't warrant repairs outside of general installation."
I need to get some windows replaced due to water leaks in the frames (some wood rot, stains).
I need to find a contractor with expertise in all areas (siding, windows, and flashing). I want to find someone who has the confidence to back their repair with a written guarantee against future leaks.
Does anyone have any advice? I am in the Northern VA area, and have contacted Case Handyman as a start, because they have a good reputation.
Are there any national certifications for Windows / Siding / Flashing / waterproofing that I should be looking for?
