ProVia fiberglass and steel entry doors with 236% ROI.







About this product
A new entry door is the single highest-ROI upgrade in the 2024 Remodeling Cost vs. Value report — 236% at resale. We install ProVia fiberglass and steel entry doors, both certified by the manufacturer for our region. Fiberglass gets the most realistic wood-grain texture and holds up best to coastal moisture; steel is the most secure and budget-friendly. Both are ENERGY STAR® certified with foam-insulated cores.
Our process
Free in-home consultation and exact door-opening measurement
Style, glass, hardware, and finish selection
Custom manufacture of the door and frame to your opening
Removal of the old door and inspection of the framing and sill
Install of the new unit: shimming, insulation, weatherstripping, and flashing
Hardware set, cleanup, walkthrough, and warranty registration

Reviews
★★★★★
"I had a terrific experience with Frank planning the sliding door and window replacement and installation in our sun room. He was extremely knowledgeable and personable and we arrived at a perfect solution for our needs at a reasonable price. Frank even offered very helpful advice related to an unrelated home improvement issue that was much appreciated. Frank is a true professional."
★★★★
"Carter and Ewan spoke to me about replacing storm doors. They were very helpful and explained anything I had questions about. It was a very pleasant experience. Thanks guys!"
★★★★★
"Today we had the pleasure of meeting with Frank and Mark to discuss a siding project for our home. Both Frank and Mark were very professional and knowledgeable. They answered all our questions and took time to explain everything to my husband and I. They offered so many options of beautiful colors which made it a little difficult for me to decide on the color but they were extremely patient with me.☺️. I highly recommend giving them a chance if you’re interested in having work done on your home . Roofing siding, windows, and doors is what they do best. We are excited and can’t wait to see the finished results of our home siding project."

Cost
Entry-door pricing depends on the material (fiberglass versus steel), whether you're adding sidelites or a transom, the glass and hardware you select, and the condition of the existing frame, sill, and surrounding framing. Rot repair or resizing an out-of-square opening adds labor. We measure on site and quote the complete installed unit — never a slab-only price that hides the real scope.
