Quick answers

How long does a energy-efficient windows & doors project take?
It depends on scope, but most projects run between 2 and 8 weeks of active work. We'll give you a realistic schedule with your written proposal — and stick to it.
Are you licensed and insured?
Yes. We're fully licensed and insured in both Massachusetts and Connecticut. We'll provide proof of insurance and license numbers before any work starts.
Do you handle permits?
Yes — pulling permits, scheduling inspections, and meeting code is all part of the job. You don't need to deal with the town.
How do you price the work?
Fixed-price proposals based on your scope and material choices. The number you sign is the number you pay, barring scope changes you approve in writing.
