Hillsdale, NJ Roof, Gutter and Foundation Contractor
NJ Gold Star Construction serves Hillsdale, NJ with roofing, gutters, siding, chimney repair, masonry and foundation repair. Hillsdale sits lower than Westwood on the Pascack Brook, so its flood warnings often come first, and we plan exterior drainage accordingly. Licensed (NJ HIC #13VH13359900) and insured.
Local reporting on the Pascack Brook notes that Hillsdale sits lower than Westwood, which is why flood warnings here tend to arrive earlier. A low lot changes the priorities: water has to leave the roof, the gutters and the foundation edge without finding its way back.
Our work in Hillsdale starts with an inspection and a written scope. The borough building office does not issue permits after 2:00 p.m., so we plan permit pick-ups for the morning.

Hillsdale sits lower than Westwood: what a low lot changes about a roof job
Local reporting notes that Hillsdale sits lower than Westwood on the Pascack Brook, so its flood warnings often arrive first. A roofing contractor in Hillsdale, NJ should therefore treat the roof, the gutters and the ground at the foundation as one drainage system, because a low lot has the least room to absorb extra water.
The Pascack Press reported that Hillsdale is lower than Westwood, which is why flood warnings often reach Hillsdale first. Hillsdale was also named in the 2024 request by Pascack Valley mayors asking the state to address flood mitigation. None of that tells us anything about your particular street, and we do not claim it does. What it tells us is how to prioritize.
On a low lot, small drainage mistakes cost more. A downspout that empties beside the wall, a patio that slopes toward the house, or a gutter that overflows at a corner can all put water where the ground is already saturated. The roof is the first step in a chain, and the chain is only as good as its last link.
Where we look first in Hillsdale
- Valleys and flashing, where concentrated roof water enters the gutter.
- Gutter size and downspout count, which fix how much water the system can move.
- Splash and soil line at the base of the siding.
- Grade at the foundation and the first ten feet beyond it.
Our roofing services, gutter services and foundation repair pages describe each of those steps, and a roof repair estimate begins with a hands-on inspection of all of them.
Grade, slope and wall cracks: reading the ground around a Hillsdale foundation
The U.S. Department of Energy’s Building America guide calls for discharge at a sloping grade at least 5 feet from the foundation, and for buried drains pitched at least 0.5 inch per foot away from the home for 10 feet. If soil slopes toward your wall, or cracks keep reopening, the ground is part of the problem.
A leaking vent "patch" we replaced
| What you see | Common cause | First step |
|---|---|---|
| Hairline vertical crack that does not widen | Normal shrinkage in concrete or block | Mark it, check it after a season, seal if damp |
| Damp stripe along one wall after rain | Downspout or grade on that side | Extend the downspout, regrade, re-test after the next storm |
| White crusty deposit on brick or block | Moisture moving through the masonry | Find and stop the water source, then clean |
| Stair-step crack in brick or block joints | Movement or settlement | Have it inspected before any cosmetic repair |
| Horizontal crack or bowed wall | Soil pressure on the wall | Treat as structural and call for an inspection |
Foundation work is the most expensive item in this section, so the first job is to separate drainage problems, which are cheap to fix, from structural ones, which are not. Drainage comes first for a simple reason: a wall that stays dry rarely gets worse.
The Building America Solution Center gives targets for how water should leave a house: discharge to daylight at a sloping grade at least 5 feet from the foundation, lateral pipe pitched about 5/8 inch per foot, and, if the pipe is buried, a slope of at least 0.5 inch per foot away from the home for the first 10 feet. Homes without gutters need splash protection, with foundation walls extending at least 16 inches above the final grade. Compare those figures with what you see outside your wall.
The 2:00 p.m. permit cutoff and the Hillsdale inspection windows
Hillsdale’s building office states that permits will not be issued after 2:00 p.m., and it posts inspection windows by trade: building inspections run Monday and Wednesday afternoons and Tuesday and Thursday mornings. Inspections are booked by phone. We plan permit pick-ups for the morning and schedule each stage inside those windows.

| Trade | Posted window |
|---|---|
| Building | Mon/Wed 3-7 p.m.; Tue/Thu 8 a.m.-12 p.m. |
| Plumbing / mechanical | Mon/Fri 1-5 p.m.; Wed 7-11 a.m. |
| Electrical | Tue-Thu 9 a.m.-1 p.m. |
| Fire | Mon/Wed 3-6 p.m. |
| Certificate of continued occupancy | Tue 4-6 p.m. |
Most delays in a permitted job are scheduling delays. Hillsdale’s department page makes the rules unusually clear. The office is open Monday through Friday, 8:00 a.m. to 4:00 p.m., but “permits will not be issued after 2:00 p.m.” The page also lists inspection windows, subject to change, and tells residents to call 201-722-2612 to make an appointment.

Siding at the base of a wall: where low, wet lots lose it first
The bottom three feet of a wall take the most abuse on a wet lot: splash from the ground, lawn spray, snow piled against the house and water running down from a failed gutter. Siding that sits too close to grade, or that lacks proper flashing behind it, rots the sheathing quietly for years before a stain appears.
Brick stoop and white rails
Siding looks like a cosmetic layer, but its job is to shed water over a hidden water barrier. In a low-lying town like Hillsdale, the failures cluster near the ground, around windows and doors, and under roof-to-wall intersections where roof water hits the wall instead of the gutter.
Checks you can make without a ladder
- Soft or discolored boards within a foot of the soil line.
- Lifted or cracked courses beside downspouts, where water arrives in volume.
- Gaps around window and door trim where caulk has failed.
- Siding that touches mulch, soil or a patio surface instead of clearing it.
A small area of damage is a siding repair job, and the repair should include a look behind it at the sheathing and flashing. A larger problem, or siding at the end of its service life, is a siding installation conversation. Older homes may also trigger federal lead-safe rules for work that disturbs paint, which we cover in the FAQ below.
Selling a Hillsdale house? Exterior items buyers' inspectors flag first
Hillsdale posts a certificate of continued occupancy application for one- and two-family homes and a zoning requirements sheet, so a sale involves borough paperwork. We have not reviewed the borough’s CCI checklist, so ask the building office what it includes, and fix visible exterior defects before listing.
Full re-roof with the landscaping tarped
The borough’s page lists a “CCI application form” for change of occupancy and one- and two-family dwellings. We have not opened the form and do not state what it requires, so the first call for a seller is the Building Department. What we can say from experience is where buyers’ inspectors usually look.
- Roof. Missing or lifted shingles, exposed nails, and damaged flashing at the chimney and vents. A roof repair before listing is cheaper than a credit at the table.
- Chimney. Cracked crowns, loose bricks and missing caps; see our chimney services page.
- Gutters and grade. Overflow, loose hangers and downspouts that dump at the wall.
- Steps and walks. Cracked treads and loose railings; our masonry steps and walkways work addresses both.
- Decks. Loose guards, soft framing and ledger problems; deck repair pages explain the fixes.
We give written estimates for each item so you can decide what to do before an inspection report decides for you. Neighboring towns have their own paperwork; compare Westwood and Park Ridge if you are weighing a move within the valley.

Frequently asked questions
Does Hillsdale's flood history change how you price a job?
It changes what we inspect, not the price formula. Because Hillsdale sits lower than Westwood on the Pascack Brook, we look harder at gutter capacity, downspout discharge and grade, and we say so in the written scope. Any extra drainage work is itemized separately so you can decide.
What time must I pick up a permit in Hillsdale?
The borough states that permits will not be issued after 2:00 p.m., although the office stays open until 4:00 p.m. on weekdays. We plan permit pick-ups for the morning. Check the department page or call the borough, since posted hours can change.
How do I schedule an inspection in Hillsdale?
The borough tells residents to call 201-722-2612 to make an appointment, and posts building inspection windows of Monday and Wednesday afternoons and Tuesday and Thursday mornings. We book each stage of our jobs inside those windows and tell you the date in advance.
Do you repair foundation cracks in Hillsdale?
We repair cracked, spalling and water-damaged foundation walls, and we start by finding why water is reaching the wall. A hairline shrinkage crack is a different job from a bowed wall, so we inspect first and give a written scope before any work.
Is lead paint a concern if my Hillsdale house is old?
Possibly. The EPA’s Renovation, Repair and Painting rule requires contractors paid to disturb paint in homes built before 1978 to be lead-safe certified and use lead-safe work practices. If your house predates 1978, ask any contractor for that certification before siding or trim work.
Can you repair siding without replacing the whole wall?
Often yes. We replace damaged courses, check the sheathing and flashing behind them and match the profile as closely as the product allows. If the rest of the wall is near the end of its life, we say so, and give both options in writing.
