Home repair costs in Boston, MA

The house this page is using

If you are pricing a water heater, a mini-split, or a move to Boston, start with the house this page uses as an example: built around 1940, about 1,400 square feet. triple-deckers and older wood houses, oil and gas, expensive crews You will see a low, a typical, and a high. A fair bid for that same job should land inside the range. A bid far above the high number is either a different job or a number you should question.

Jobs people actually price in Boston

A straightforward 40-gallon electric water heater replacement in Boston typically costs $2,000, with a range of $1,560 to $2,690. A window air conditioner for one room is typically $700. A single-zone mini-split for the example home is typically $8,140, from a cooling sketch of about 31,600 Btu/h. A local move for a two-bedroom household is typically $1,840. Those are installed or move-day figures, not a re-pipe, not a whole-house air conditioner, and not a cross-country truck.

An 80,000 Btu gas furnace, same ducts, typically costs $5,350 in Boston. A roof on the example home — planning area 1,610 square feet, not a measurement — typically costs $12,870 to tear off and reshingle. Open-attic cellulose aimed at R-60 typically costs $3,330. A planning year of gas heat is about $1,420 at the $1.50 a therm you typed in the bar. Heat-pump heat at the local electric rate is about $3,140. Cooling is about $370. Each of those has its own page so the numbers are not mashed into one “home cost.”

What is local here, and what is not

Boston is in IECC climate zone 5A. A typical year here has about 5,630 heating degree days and 750 cooling degree days, against 4,000 and 1,400 in the national reference. Local labor is 1.32 times a national crew, which is 32% higher. Planning electricity is 29.5¢ per kilowatt-hour, 12.7¢ above 16.8¢. Eversource and National Grid split the region. Electric rates are high. Oil heat is still in the older stock.

Boston combines a high labor factor with a high electric rate and an old wood building stock. Triple-deckers mean stairs, shared chimneys, and water heaters that serve one floor but vent into a stack nobody has lined since 1970. Wellholt prices one in-unit swap. A building-wide conversion off oil is not this page. Permits are not optional.

Rent, sitting next to the repair on purpose

A one-bedroom planning rent is $2,500 a month. A two-bedroom is $3,200. These are not listings. They sit next to the repair prices so a low labor rate is not mistaken for an affordable city. On a $72,000 household income, that two-bedroom is about 53% of gross monthly income. Put your own income in the move calculator. If you rent, a window unit and a move are usually your decision. A water heater, an electrical panel, or a mini-split on the outside wall belongs to the owner. Use the range to read their quote.

How to use this without fooling yourself

Set your city to Boston at the top of the page, then open the calculator for the job you are actually pricing. Your square footage replaces the 1,400 square foot example. The gas line follows the price per therm in that same bar. Low means an easy version of the same scope. Typical means the example house. High means the same machine with worse access, a code fix, or a second trip. Reviewed 2026-09-01.

Installed costs start from published national ranges and scale the labor share. Rents are planning medians, not listings. Reviewed 2026-09-01. Ask for the written scope before you compare any bid with the high number.
