What we do · Bergen County, NJ

The whole exterior, and the house behind it.

Roof, walls, windows, gutters and decks by our own crews on one schedule, across Bergen County — and kitchens, additions and new homes, run the same way with licensed plumbers, electricians and HVAC contractors where the job needs them. Hire us for one of these, or for the whole house.

Urgent repairs

Wind, hail, ice and fallen limbs. We hold a 24-hour assessment window for Bergen County year-round, dry the building in first, and document the damage properly — photographs, measurements and a scope your insurer can actually process.

Siding

Cedar, fiber cement, vinyl, engineered composite and clapboard, installed as part of the building envelope rather than as a facelift. What goes on behind the siding — the housewrap, the flashing, the drainage plane — is the part that decides how long the front of it lasts.

Windows & doors

Full-frame and insert replacement, entry doors and sidelights, and repair of the original wood sashes that are worth keeping. On a 1920s colonial, replacing every window is often the wrong answer — and it is the expensive one.

Gutters

Seamless aluminum and copper, formed on site and sized to the roof area actually draining into them. Most gutter failures in this county are not the gutter — they are a downspout discharging two feet from a foundation, or a valley dumping four hundred square feet into a five-inch K-style.

Decks

Composite, cedar and hardwood decks on pressure-treated framing that is through-bolted and flashed to the house — the connection almost every deck failure traces back to. Rebuilt on the old footprint or new, with the permit filed and the inspection booked as part of the job.

Kitchens

Full kitchen renovation, from the wall that comes out to the trim that goes back on. The things that decide whether a kitchen works — what carries the ceiling once the wall is gone, where the water and waste run, whether the panel can take the range — are settled before anything is ordered.

Additions

Rear extensions, second stories, dormers, sunrooms and porches. It starts with a current survey and your zone's setbacks and coverage limits, before anyone draws something the lot will not allow, and it ends with a roof line and trim that look as if they were always there.

New construction

Custom homes built from the ground up, managed from the foundation to the certificate of occupancy. The house pictured is one of ours in Wyckoff, photographed as it went up; this year we have also been building a custom home on the Hudson in Edgewater.

Not sure which of these you need?

Most people call us about a symptom, not a service.

A stain on a bedroom ceiling could be the roof, the flashing, the gutter, an ice dam or a plumbing line above it. Tell us what you can see and we will work out which one it is — on site, for free.

Stain on a ceiling

Usually flashing, an ice dam or a plumbing line — far less often the field of the roof.

Shingles in the yard

After wind, the damage that matters is usually the lifted ones still on the roof.

Water in the basement

Start at the downspouts. Foundation water is a roof-drainage problem more often than a foundation one.

Drafty, cold rooms

Could be windows, could be the attic. We will tell you which before you spend on the wrong one.

One company for the roof, the walls and everything between them.

Free written estimate with photographs, usually within a couple of days of the visit.
