Window & Door Installation in Charleston, SC
Window and door replacement is where a lot of Lowcountry water damage starts. The unit itself is rarely the problem. It's the flashing, the sill pan and the sealant joint that fail, usually somewhere you can't see until the drywall tells you.
We install to the manufacturer's flashing spec, not to whatever's quickest, and we finish the interior and exterior trim so the new work doesn't look like a patch.
- Typical timeline: 2 days to 2 weeks
- Best for: Drafts, fogging, rot and storm hardening

We have used Pascoal Carpentry for three large projects in our home. They have created a beautiful built in office cabinetry for our main floor office.
Professional Excellence. I am extremely impressed by their knowledge, skill, and professional and polite crew. I had been having ongoing roof leak issues for two years.
Absolutely amazing team. Very polite and extremely professional. I can't describe the level of attention they put into building this lovely porch roof from scratch.
