We don't install oddball custom sizes or specialty architectural doors - that's a different trade with different suppliers, and we'd rather tell you that up front than take the job and make you wait on parts we don't normally stock. We also don't do general construction, framing repair, or siding work around the opening; if your header or jamb is damaged, that's a carpenter's job first.
Here's the honest limitation: parts for the older end of our service area's housing stock - doors and openers from the early-to-mid 1960s through the 70s - can take longer to source than parts for anything built after 1983, since that's closer to the median build year and the more common hardware. If your door falls into that older bracket, we'll tell you at the time we quote it, not after we've already started.
We don't offer emergency guarantees or same-day promises as a blanket policy, because that's not something we can honestly commit to on every call, every day. We'd rather give you a real estimate on when we can get there than a line that sounds good on a page.
