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
★★★★★
"We are so happy with our decision to use Coastal for our entry door. From the initial meeting with Roger to the measuring to the communication while waiting for the door to be built to the install, everyone we encountered was professional and friendly. Our new door is beautiful and well made. We love it!"
★★★★★
"My husband and I met with Erik in looking for a quote for siding, replacing a door along with two windows. He was wonderful and a pleasure to work with. And patient as we made a few changes and few different times. He was very good at explaining pricing and how things are broken down. We felt comfortable and signed contracts for our home project. Looking forward for job completion and seeing before and after.TC from Lowell"

"This is a pre-install review. Amazing experience with Coastal Windows and Exteriors so far. Ewan was our product specialist. He has been extremely helpful and responsive in the whole process. Our communication throughout the project was very smooth. At this point, we are looking forward to our new patio door installation with Coastal Windows and Exteriors.We have completed the patio door installation in April. I am very satisfied with the service, the team was professional and efficient. They were great to work with."

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.
