Why this matters more in Lawrence
Lawrence's housing stock leans heavily on older triple-decker and multi-family buildings from its mill-city era on the Merrimack River. Older multi-family buildings like these are often where air sealing and insulation make the biggest visible difference in comfort and monthly bills, since a lot of that stock predates modern building codes.
Because Eversource delivers gas in Lawrence (having taken over the former Columbia Gas of Massachusetts territory in 2020) and National Grid delivers electricity, insulation work here can be funded through either side of the Mass Save program depending on your heating fuel, though you don't need to sort that out yourself before applying.

Common questions
How much does insulation cost after the rebate in Lawrence?
Mass Save covers 75% of attic, wall, basement, and air-sealing costs for all Lawrence homeowners. Income-eligible households (below 60% Area Median Income) pay $0 out of pocket.
Do renters in Lawrence qualify?
No. Insulation rebates go to the property owner. If you rent, the free Mass Save home energy assessment is still worth requesting through your landlord.
Your utility: National Grid
National Grid is the local electric utility for Lawrence. The insulation rebate above comes from a state-wide program, so which utility bills you doesn't change what you qualify for. Where it can matter: National Grid is who to contact about your home's electrical service capacity if your installer flags an upgrade, and who bills the electricity your new equipment uses once it's running. Some utilities layer their own incentive on top of the state rebate, so it's worth a quick call to National Grid to ask directly.
What Lawrence's winters mean for this upgrade's payback
Lawrence's average January daily low has been -5.9°C over the last 10 winters (2015-2024), with a coldest recorded day of -26.7°C , based on real measured data. The colder it gets outside, the more a poorly insulated wall or an old window actually costs you in heat loss, which is the real math behind why this rebate exists and why the payback tends to be faster in a climate like Lawrence's than in a milder one.
