When homeowners start comparing bids for window replacement in Lexington SC, the license question should come up early, not after the deposit is paid.

That brings up another practical step: ask about permits. Homeowners often search "do I need a permit to replace windows in Lexington County" because the answer can depend on whether the work is a like-for-like replacement or a change to the opening itself.

A short checklist makes the verification step easier: - Match the company name and license number to the South Carolina LLR record. - Ask whether the license is active and whether there are restrictions. - Ask for insurance documentation before any materials are ordered or crews are scheduled. - Find out who is responsible for permits and whether the people doing the work are employees or subcontractors. - Get the scope in writing, including products, flashing, trim, cleanup, and warranty terms.
