What We Build

Capabilities

New England-style home exterior at dusk — decorative photo, not an MCG project

Built For New England

Every project is planned for the weather, code, and site conditions it actually has to hold up to.

From framing through final finish, MCG coordinates the trades and details — flashing, fasteners, and structure — that don't show up in a photo but decide whether the work lasts.

One point of contact

A single project contact from your first estimate through final walkthrough.

Clear scope in writing

You'll know what's included, and what isn't, before work starts.

Built for New England

Work planned around real Massachusetts and New Hampshire weather and code.

Serving the Merrimack Valley region of Massachusetts and New Hampshire.
