WHAT WE DO

— 01 / SERVICES

01

Additions & New Builds

From in-law suites to full second stories — framed square, finished clean, permitted properly.

02

Kitchens & Bathrooms

The rooms you actually live in, rebuilt to work as hard as you do. Design help included.

03

Decks & Porches

Composite or classic lumber, built to shrug off New England winters for decades.

04

Roofing & Siding

Tight, dry, and done fast. Emergency repairs when the weather doesn’t wait for you.

05

Excavation & Site Work

Grading, drainage, foundations — we bring our own iron, so your schedule stays ours to keep.

06

Basement Finishing

Turn the storage floor into the favorite floor. Dry, warm, and up to code.

02 / ABOUT US

A pickup truck, a dream, and 38 years of keeping our word.

Stanley Kowalski Sr. started this company in 1987 with one truck and a simple rule: treat every home like it's your own. Two generations later, that rule hasn't changed — the trucks just got bigger.

We're not the biggest outfit in the High Country, and that's the point. When you call, you get a Kowalski. When we quote, the number holds. And when we leave, the site is cleaner than we found it.
