The Third Estimate Corporation

The Third Estimate Corporation is a full-service exterior remodeler—Siding contractor, Contractor, Gutter cleaning service, PVC windows supplier, Roofing contractor, Window installation service, and Window supplier—so you can tackle multiple projects with one team. Request an itemized proposal (ask if they offer a free estimate) that compares material and design options like vinyl vs. fiber cement siding, asphalt vs. metal roofing, and double- vs. triple-pane PVC windows to balance curb appeal, durability, and energy efficiency. Before you book, confirm installation timelines, on-site project management, permit/HOA handling, and written warranties that cover both labor and manufacturer defects. To maximize value, ask about financing, seasonal promotions, and bundled pricing for roof-siding-gutter-window packages, and schedule a thorough inspection to catch leaks, rot, or ventilation issues early.
