How Can We Help?

Some Mercer projects are additions to established yards in older neighborhoods, others are newer homes with a blank backyard. Either way we design the pool and everything around it, then build it with one crew.

We design and build inground pools, four fiberglass pool brands we install and BaduJet swim jet.

Mercer County Pools

A Pool Built for the Way You Actually Use Your Backyard

Northern Mercer around Hopewell and Princeton sits partly on Newark Basin shale and diabase rock, while southern Mercer around Hamilton and Robbinsville is sandier Coastal Plain soil. Sandy ground digs easily but needs support for the excavation walls and a plan for groundwater.

Fiberglass works well on both kinds of ground when the base and backfill are done right. We are an authorized dealer for River Pools, Imagine Pools, Latham and Glimmerglass, and every build gets a Pentair equipment package.

Every project starts with a clear plan. We look at your yard, how you want to use the space, and what your budget is, then handle the permits and the build so you’re never left guessing. The goal is simple: a pool that looks right, works right, and holds up for years.

Outdoor Living

Your Backyard Is Where Real Life Happens

We build paver and stamped concrete patios, pavilions, walls and lighting. In historic districts, like parts of Princeton, extra design review can apply to visible work, so we check before planning.

Seasonal Care

Keeping Your Mercer County Pool Easy to Own

We handle spring openings and fall closings and check the Pentair equipment both times so small problems get caught early.

We take care of the regular upkeep and the seasonal work, openings, closings, and equipment checks, so there are no surprises and nothing falls through the cracks. You always know exactly who’s looking after your pool, because it’s us.
Your pool is where a lot of family memories get made, and it’s worth protecting. We show up when we say we will and keep your pool in the kind of shape that makes you glad you built it.
