How do you keep a Chelmsford 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 is a change order, and how should it work?

A change order documents any change to the agreed scope, its cost, and its schedule impact — signed by both parties before the work happens. Verbal changes are how projects end in disputes. If a contractor is doing extra work without written change orders, neither of you can prove later what was agreed.

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 should I check before hiring anyone?

Current HIC registration and Construction Supervisor licence, a certificate of insurance sent directly from their insurer, references from jobs of similar scope and age, and photos of their own completed work. Ask to speak to a client from a job that had a problem — how a contractor handled the difficult project tells you far more than a showcase reference.
