What we do

Every trade under one roof.

Everything below is done by our own crews on one schedule. You can hire us for one of them, or for the whole envelope and the rooms behind it.

Roofing

Repairs, full replacements, inspections and everything from a lifted ridge cap to a complete re-slating. We specify to the house rather than to whatever is on the truck — and if the field is sound and the failure is at a flashing, we will tell you that in writing.

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, 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.

Kitchens & bathrooms

Full renovations including the structural, electrical and plumbing work that sits behind the finishes. We open walls before we price them, because on a house of this age what is behind the tile is the part that decides the schedule.

Additions & decks

Dormers, rear extensions, second stories, porches and outdoor rooms — from drawings and zoning through framing, envelope and final trim. The roof and siding tie-ins are ours too, which is the part that usually gives an addition away.

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 bathroom 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 contractor for the roof, the walls and the rooms behind them.
