Homes built before 1978 need lead-safe work practices, and homes from the early 1900s and before often hide plaster walls, knob-and-tube wiring, galvanized pipes, rotted sills and out-of-level floors. Our home renovation calculator adds an allowance for these based on the age of your home, and we confirm what is behind the walls on a free site visit.

It gives a planning range, not a quote. The ranges come from Cotton Construction's own crew rates and local subcontractor pricing for the NH and southern Maine Seacoast, updated for 2026. Your exact price comes after a free site visit, once we have seen the house and you have chosen finishes.
