Concrete footings with rebar poured for a new home foundation on a Cabra Prestige Group site in Nassau County
Footings and rebar — new construction, Nassau County

A foundation is the one part of a house nobody sees and everybody depends on. We build it to the engineer's drawings, waterproof it, and have it inspected before a single stud goes up.

Every Cabra Prestige Group new home starts in the ground, and so do most extensions and full-dormer projects. We excavate, form, and pour footings and foundation walls to the engineered plans, coordinate the inspections the town requires at each stage, and waterproof the exterior before backfill — so the basement stays dry through the Long Island water table and freeze-thaw seasons.

Our foundation work in Nassau County includes full poured foundations for ground-up homes, frost-protected footings and foundations for extensions and additions, piers and footings for decks and porches, garage and basement slabs, foundation waterproofing and drainage, and structural repairs — cracked or bowing walls, settled footings, and the sill and framing damage that follows water intrusion.

Because we are the general contractor and not just the concrete sub, the foundation is coordinated with everything that comes after it: anchor bolts and sill plates placed for the framing crew, sleeves and penetrations set for plumbing and electrical, and elevations checked so the finished floors land where the plans say they will.

Questions, answered

Foundations & Concrete FAQ.

The questions Long Island homeowners ask us most about this work. Anything else — call or text (516) 343-2806.

Do you do foundation repairs, or only new foundations?
Both. We repair cracked and bowing foundation walls, settled footings, and water-damaged sills, and we pour new foundations for homes, extensions, and dormers. If you are not sure which you need, we will look at it and tell you honestly.
Does an extension need its own foundation?
Almost always. Any addition with living space above it needs frost-protected footings and a foundation or crawl space built to code and tied into the existing house. We handle the engineering coordination, permits, and inspections as part of the project.
How do you keep a new basement dry?
Exterior waterproofing on the foundation walls, proper drainage at the footing, correct grading away from the house, and sealed penetrations. It is far easier — and cheaper — to do this before backfill than to fix a wet basement afterward.
