Custom Decks in Massachusetts and New Hampshire by Lumi Construction
Licensed & Insured in MA & NH

Custom Deck Builder in Massachusetts & New Hampshire

A deck built for New England has to do more than look good in July. We design and build custom decks that handle freeze-thaw cycles, heavy snow loads, and humid summers, and still look great doing it.

Sound Familiar?

Most homeowners come to us after a bad experience, or to avoid one.

"My deck started warping and splitting after two winters."

Decks fail in New England because contractors use the wrong materials or skip proper fastening. We specify materials rated for MA and NH climate conditions.

"The permit process was a nightmare."

Decks over 30 inches require permits in most MA and NH towns. We handle every permit and inspection as part of every project.

"It looked nothing like the rendering they showed me."

We build what we design. Our project documentation is precise enough that what gets built matches what you approved.

At Lumi, we built our process around fixing exactly these problems. Here's how we work.

Why Choose Us

What Makes Lumi Different

Not generic promises. Specific reasons backed by real results.

Engineered for New England Weather.

Freeze-thaw cycles crack decks built with the wrong fasteners. We spec Trex, Azek, and other materials rated for MA and NH climate, and detail every connection point to prevent failure.

Permits and Inspections Included.

Every deck project we build is properly permitted and inspected. No shortcuts. No unpermitted structures that create problems when you sell your home.

Composite, Wood, or a Combination.

We build in Trex, Fiberon, Azek, pressure-treated lumber, cedar, and IPE. We help you choose based on budget, aesthetics, and how much maintenance you want to do.
