Scarborough is the fastest-growing town in Greater Portland, and that demand shows up in contractor availability more than in hourly rates. Crews are booked deep, so the practical cost of waiting — or of paying for an off-season start — is often the real variable here.
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.

A wide spread: 1960s–1990s subdivisions inland, older farmhouse and cottage stock in Dunstan and Oak Hill, and coastal homes at Higgins Beach, Pine Point, and Prouts Neck that sit in flood and shoreland zones. Beach-area properties carry elevation, flood-vent, and salt-exposure requirements that inland quotes never include.

Additions and structural work need a building permit plus zoning review. Coastal and marsh-adjacent parcels — a large share of the town — fall under shoreland zoning and FEMA flood-zone rules, which can dictate elevation and construction method, not just approval. Confirm the flood zone before design.
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.
Coastal exterior work concentrates from late April through October. Summer traffic and beach-season parking around Pine Point and Higgins Beach genuinely slow deliveries and crew access, which is why some contractors price shoulder-season work lower.
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.
