Gorham is one of the better value markets in Greater Portland. It is inside the commuting radius for Portland crews, lots are open and easy to work on, and site logistics rarely add cost the way peninsula jobs do.
Our Haus isn't a contractor directory. We give you the local cost math, the permit reality, and the paperwork tools — the scope, the proposal comparison, and the vault your records live in.
Based on a 1,800 sq ft siding replacement scope, adjusted by the Maine regional cost index and a Gorham metro multiplier of 0.99×. A 10% contingency reserve is included. These are budgeting estimates, not quotes.

Farmhouses and capes in the village and along the older road frontages, large 1990s–2010s subdivisions toward South Gorham and Little Falls, and student-adjacent rentals near the university. The subdivision stock is now old enough to be hitting first-generation roof, siding, and kitchen replacement.

Building permit for additions, structural work, and decks, with zoning review on setbacks. Many properties are on private well and septic, so bedroom-count changes require septic capacity sign-off. Shoreland zoning applies along the Presumpscot and at Little Sebago.
Maine requires a written contract for home-construction or repair work over $3,000. The contract must include the contractor's name and address, the work and materials, the total price, a payment schedule, start and completion dates, a warranty statement, and notice of the state's contractor-dispute mediation program. Maine does not license general contractors, so verify insurance directly with the carrier.
Exterior work runs April through November. Inland Gorham freezes a little earlier than the coast, so excavation and foundation work should be scheduled with October in mind.
Typical duration: 1–3 weeks on site for a typical single-family.
Wall area, openings, and a teardown assessment of the existing cladding layers.
Fiber cement and special-order colors carry lead times; confirm before teardown.
Old siding off, sheathing inspected, repairs at the stated unit price.
The phase that decides whether the job lasts. Housewrap, tapes, pan flashing at openings.
Product installation with proper clearances at roofs, decks, and grade.
Siding is a weather-barrier job wearing a cosmetic costume. The product line on the bid matters less than the flashing, housewrap, and window-integration details underneath — and those are exactly the lines that disappear from the cheapest quote.
Full checklist: what should be in a contractor's estimate.
We don't keep a contractor directory, and we won't pretend to. The dependable process is to gather two or three referrals locally, check the Maine registration or license rules above, confirm general liability and workers' compensation directly with each carrier, then compare the written proposals side by side against the ranges on this page.

Run it through the quote range checker. We compare it against the Maine cost index, flag line items that look high, and review the contract against Maine home-improvement rules.
Check my quoteSometimes — over one sound layer of flat siding, with the right preparation, it is legal and can be reasonable. Over multiple layers, over rot, or where window flanges need re-flashing, strip it. Any honest answer requires looking at what is on the house now.
Quality vinyl and fiber cement are routinely rated for decades, and both handle freeze-thaw well when the weather barrier underneath is detailed correctly. Cedar performs beautifully but wants a maintenance cycle. The failure mode in New England is almost never the product — it is the flashing.
