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 have been finding it a bit overwhelming to take care of my almost 20 year old house. I am so pleased to have found a company that seems to care about my needs and my complete understanding of the project. I am impressed with their professionalism, knowledge, and helpfulness, as well as with the quality of their product. I asked for and received valuable advice even a bit beyond the scope of the project. The price was very fair for the high quality of the doors and windows (and was lower than other quotes I received). I would definitely recommend consulting Coastal Windows and Exteriors on any door or window project. They do high quality work."
★★★★★
"Coastal windows replaced our front door. They did a fantastic job. Professional, courteous, and stand behind their craftsmanship. We are thrilled with our new front door!"
★★★★★
"Very professional and knowledgeable staff. We have worked with the team at Coastal for some time now and couldn't recommend them any higher for anyone looking for new windows, doors or siding in the MA / NH area."

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.
