Your backyard,
elevated.
Custom pools, natural swim ponds, and complete outdoor living spaces — designed for New England families and built to last a lifetime.
Complete outdoor transformation.
Built for New England.
Built to last.
We design and build custom pools and outdoor spaces that survive NH and MA winters as well as they perform on a summer afternoon. Every project starts with a real conversation — not a sales pitch.
Based in Alton, NH, we serve the Lakes Region, Seacoast, and into Massachusetts. When you work with Summit, you work directly with the people who build it — and through our sister company American Landscape Construction, we handle your pool and your patio.

A pool that works
with nature, not against it.
Natural swimming pools use biology — not chlorine — to keep water crystal clear. They're stunning, sustainable, and better for your whole family. Summit is one of the very few builders in NH and MA who truly knows how to build these right.
Built on trust.
Proven by results.
We're not a national chain. We're your neighbors — and we build every project like our reputation depends on it. Because it does.
One Owner. Two Companies. Total Transformation.
Summit builds your pool. American Landscape Construction builds your patio, coping, and outdoor space. Coordinated under one roof — no hand-off headaches.
Licensed & Insured in NH & MA
Fully licensed in both states. You're protected from the first day of excavation through your final walkthrough.
Winter-Ready Construction
Every build is engineered for freeze-thaw cycles and New England soil. Your investment is protected long after the season ends.
Transparent Pricing. No Runaround.
Honest budget ranges, clear timelines, direct communication. We tell you what things cost before you commit — not after.
The pool is just
the beginning.
Every great pool needs a great surround. American Landscape Construction — our sister company under the same ownership — handles everything around the water: patios, pool coping, granite steps, retaining walls, and full backyard hardscaping.
One vision. One owner. One seamless build.
Why bundle pool + hardscape?
One point of contact — same owner manages both scopes. No finger-pointing between contractors.
Seamless scheduling — pool excavation and patio work are coordinated from day one.
Consistent quality — same standards, same accountability across every square foot of your backyard.
Better design outcomes — pool and patio are designed together, not bolted together after the fact.
Simple. Clear. No surprises.
