Dumont, NJWindow Installation & Glass Repair
Dumont is a twenty-minute run northeast from our Garfield shop, up on the low ridge between the Hackensack and Tenakill valleys — the borough was incorporated as Schraalenburgh (Dutch for 'low ridge') in 1891 and took the name of its first mayor, Dumont Clarke, in 1898. Today it fits just under 18,000 residents into two square miles, and the housing math is what matters to a window shop: of roughly 6,500 units, nearly a quarter predate 1939 and about six in ten went up between 1940 and 1969.
That mix generates two distinct call types. The postwar Capes, colonials, and split-levels are on their second or third round of windows, so fogged insulated glass and stiff early replacements dominate the schedule. The prewar quarter of town still carries weighted wood sash, where the honest choice between restoring and replacing changes house by house — we quote it that way.
What We Work On in Dumont
A fully built-out grid of 1940s-60s Capes, colonials, and split-levels, with prewar blocks threaded through. Washington Avenue is the commercial spine and Madison Avenue the principal east-west street, while Knickerbocker Road (CR 505) traces the eastern border past the 66-foot Camp Merritt Memorial obelisk — the granite shaft at the Dumont-Cresskill traffic circle, dedicated by General Pershing in 1924, marks the center of the WWI embarkation camp that moved over a million soldiers through this ground. Two 18th-century Dutch stone houses on Washington Avenue survive from the Schraalenburgh era — the 1780s Derick Banta House at 180, serving since 1926 as the Dixon Homestead Library, and the 1724 Daniel Demarest House at 404 — and the 1801 sandstone Old North Reformed Church stands at 120; all are on the National Register, but Dumont has no historic district.
Common Dumont Jobs
- Second-generation replacement of tired early vinyl in postwar Capes and split-levels
- Sealed-unit swaps in postwar homes whose builder-grade double panes have hazed over
- Weighted wood sash repair and IGU retrofit on the pre-1939 blocks
- Laminated acoustic glass for bedrooms near the CSX freight corridor
- Small-storefront glass along the Washington Avenue business district
Dumont's landmark buildings — the Banta and Demarest stone houses and Old North Church — are individually listed on the National Register rather than grouped into a district, so no preservation board stands between a homeowner and a window permit anywhere in town. When the scope calls for filing, we handle it under NJHIC #13VH13970900 through the Building/Zoning Department at Borough Hall, 50 Washington Avenue.
No interstate or state highway crosses Dumont, so the borough's loudest neighbor is the old West Shore Railroad line: passenger service ended in 1959, but CSX River Subdivision freight trains still roll through at all hours, and their low-frequency rumble reaches bedrooms near the corridor. Laminated glass and asymmetric pane thicknesses handle that band far better than standard double panes. The other exposure is water from below — Hurricane Ida damaged the borough's sanitary sewers badly enough in 2021 that federal funding was later secured to modernize the system, upgrade pump stations, and add emergency backup generators, and basements that backed up that September are where we now find rusted, rotted, or racked basement window frames.

Dumont Window FAQ
We're near the freight tracks and the trains rattle the house at night — will new windows help?
With the right glass, yes. Freight rumble is low-frequency, which equal-thickness double panes barely touch; laminated glass with two different lite thicknesses damps it meaningfully, and an interior insert adds a second air gap where frames are sound. We're honest about limits, though — vibration carried through the foundation isn't a window problem.
My 1948 Cape got replacement windows decades ago and half are fogged now — new glass or new windows?
Depends on the frames. Where sash and frame are still square, we replace only the failed sealed unit — templated at the measure visit, fabricated within the week, and set in about half an hour per opening. Where the vinyl has warped or sills have gone soft, full replacement beats paying to fix the same window twice.
Does Dumont require a permit for window replacement, and is there any historic review?
Same-size insert replacement usually doesn't need one; enlarging an opening or converting to egress does. The Building/Zoning Department at 50 Washington Avenue — (201) 387-5034 — handles filing, and since the borough has no historic district there's no preservation review to clear, even on the oldest Washington Avenue blocks.
