How do you keep a Lexington project from running over budget?

Two things: a genuinely itemised estimate up front (not a lump sum), and pricing the likely unknowns before we start rather than after we find them. Change orders happen when scope changes — they shouldn’t happen because the original number was optimistic.

Do you subcontract everything?

No. Framing and structural work — the phase most likely to go wrong — is our own crew. Electrical, plumbing and HVAC go to licensed trade partners we’ve used for years, scheduled and inspected by us.

What should I ask before signing with any contractor?

Their MA HIC registration number, a current certificate of insurance, references from projects like yours, a written itemised scope, and confirmation they’re pulling the permits. Anyone who hesitates on those five has told you something.

What does a general contractor actually do?

The general contractor is accountable for the whole project: scheduling and coordinating every trade, pulling permits and meeting inspectors, ordering and staging materials, keeping the site safe and clean, and being the single point of responsibility when something goes wrong. On a job with framers, electricians, plumbers, HVAC, and finish trades, the sequencing is most of the value.

What licensing should a contractor have in Massachusetts?

For residential work, ask for the Home Improvement Contractor (HIC) registration and confirm it is current with the state. Structural work also involves a licensed Construction Supervisor. Ask for the numbers, verify them yourself on the state's registry rather than taking a number on a truck at face value, and confirm liability insurance and workers' compensation coverage in writing.

How should a construction contract be structured?

In Massachusetts a home improvement contract must be in writing, signed by both parties, with a clear scope, a total price, a payment schedule, and start and completion dates. State law limits the deposit a contractor may require before work begins. Be wary of any contractor asking for a large payment up front or working without a written contract — that is the single most common pattern behind the complaints the state receives.
