Cost & Pricing
How much do replacement windows cost in New Jersey?+
It depends on the number of windows, the style, the frame material, the glass package, and whether it's an insert or full-frame installation — so we quote after an in-home measurement rather than guessing. To plan a range now, use our free window cost calculator, which uses real NJ market rates. Vinyl double-hung inserts are the value end; fiberglass, clad, or wood frames with triple-pane or laminated glass step up from there.
Why does the per-window price vary so much between quotes?+
Because 'a window' isn't one thing. Frame material (vinyl vs fiberglass vs wood), glass package (standard Low-E vs triple-pane vs laminated), the window style, and especially insert versus full-frame installation can easily double the per-opening price. Per-window cost also drops as the count rises, since the crew mobilizes once. Make sure competing quotes specify the same material, glass, and install method before you compare them.
Do you offer financing?+
Yes. We work with Hearth, a lending marketplace that shops several banks on one application — checking is a soft pull that does not affect your credit score. Precision is the contractor and referring broker, not the lender, and all financing is subject to credit approval by Hearth's lending partners. We also plan phased work when that is the better answer: worst windows first, or the roof this year and the windows next.
Is the in-home measurement and estimate free?+
Yes — free, in-home, and no obligation. Accurate window pricing requires measuring each opening and checking the frame and sill condition, which is exactly what a calculator can't do. We measure, recommend, and give you a written quote at no cost.
The Process & Timeline
How long does window installation take?+
Most homes are done in one to two days depending on the number of windows and whether it's insert or full-frame work. A handful of windows can be a single-day job; a whole-home full-frame project with trim work runs longer. We give you a realistic schedule at the quote.
Insert or full-frame replacement — which do I need?+
An insert (pocket) replacement fits a new window into your existing, sound frame — faster, less invasive, less expensive. A full-frame replacement removes everything to the studs and is the right call when the frame or sill is rotted, when you're changing the window size, or when there's hidden water damage to address. We confirm which your home needs at the measurement and never upsell a full-frame where an insert is correct.
Will I need a permit to replace windows in NJ?+
It depends on the town and the scope. Like-for-like insert replacements often don't require a permit, while full-frame replacements or changing an opening's size frequently do, and egress requirements apply to bedroom and basement windows. We know each town's requirements and pull permits where they're needed.
Do you remove and dispose of my old windows?+
Yes. Removal and disposal of the old units is included, along with cleanup and a magnet sweep for any fasteners. You're left with new windows installed and the old ones hauled away.
My home is older — what about lead paint?+
Homes built before 1978 may have lead-based paint, and window work disturbs it. We follow EPA RRP (Renovation, Repair, and Painting) lead-safe work practices on pre-1978 homes — containment, safe removal, and cleanup — to protect your family during the install.
Materials & Glass
Vinyl, fiberglass, or wood — which frame is best?+
Vinyl is the value leader and the right choice for most NJ homes — low-maintenance and energy-efficient. Fiberglass is stronger and more dimensionally stable (great for large openings and extreme temperature swings) at a higher price. Wood and clad-wood suit historic homes and buyers who want a specific look, with more maintenance and cost. Our vinyl-vs-wood-vs-fiberglass guide breaks down the trade-offs for the NJ climate.
What glass package should I get for New Jersey?+
Double-pane with a Low-E coating and argon fill is the sensible standard for NJ — it cuts heat loss in winter and heat gain in summer. Triple-pane is worth it for maximum efficiency, noise reduction, or north-facing exposures. Laminated/impact glass adds storm and security protection (and serious sound reduction) and is worth considering near the shore or on busy roads.
My windows are foggy between the panes — can that be fixed?+
Foggy or cloudy glass means the seal on the insulated glass unit (IGU) has failed and the gas fill is gone, so the window has lost much of its insulating value. In many cases we can replace just the glass unit rather than the whole window — keeping your existing frame and sash — which is far less expensive than full replacement. We'll tell you honestly whether glass-only replacement or a new window makes more sense.
What's the most energy-efficient window?+
Look at two numbers on the NFRC label: U-factor (lower is better — how well it insulates) and SHGC (solar heat gain — moderate is ideal for NJ's mixed climate). A triple-pane window with a low U-factor is the most efficient, but a quality double-pane Low-E/argon window captures most of the benefit at a lower price. Energy Star certification for the Northern climate zone is a reliable shortcut.
Do you do custom shapes and specialty glass?+
Yes. Beyond standard windows we do architectural and specialty shapes (arches, round-tops, trapezoids), glass railings and balconies, shower enclosures, storefronts, tabletops, shelving, and decorative, frosted, tinted, tempered, and laminated glass. Our Garfield glass shop is a full custom fabrication shop, not a reseller.

Energy & Rebates
Are there rebates or tax credits for new windows in NJ?+
Not for windows, as of 2026. The federal Energy Efficient Home Improvement Credit (Section 25C) was repealed for any property placed in service after December 31, 2025, so a window installed in 2026 earns no federal credit. And none of the NJ utility programs we checked — PSE&G, JCP&L, Atlantic City Electric, Rockland Electric — pay a rebate for replacement windows; they pay for air sealing, insulation, ducts, HVAC and water heating, which can be real money if your project is bigger than windows. If your windows were installed in 2025, ask your tax preparer about the 2025 return. We provide the product documentation (NFRC ratings, Energy Star certification) either way. See our NJ window rebates guide for the program-by-program detail.
Will new windows actually lower my energy bills?+
If you're replacing old single-pane or failed double-pane windows, yes — drafty, leaky windows are a real source of heat loss, and sealing the envelope with efficient units reduces heating and cooling load. The honest caveat: windows are one part of the envelope, and the payback period varies with how bad your current windows are. We'll give you a realistic picture rather than overpromising.
Licensing & Service Area
Are you licensed and insured?+
Yes. We're registered with the NJ Division of Consumer Affairs as a Home Improvement Contractor (NJHIC #13VH13970900) and carry full general liability and workers' compensation coverage. We'll provide our certificate of insurance on request — a legitimate NJ contractor always can.

What areas do you serve?+
All 21 New Jersey counties from our Garfield shop, same-day, including the shore and south.
Do you do commercial glass and storefronts?+
Yes. Beyond residential windows, we install and repair commercial storefront glass, glass partitions and doors, and handle commercial window leak repair for retail, office, and institutional buildings across NJ — including emergency board-up and reglaze after a break-in.
What is a window repair person called?+
A glazier — the trade title for someone who cuts, fits and installs glass, including replacing a broken pane or a failed insulated glass unit. Broader window work spans more than one trade: a glazier handles the glass, a window installer sets the unit in the opening, and a carpenter deals with a rotted sill or a rebuilt jamb. In New Jersey the title is not the thing to check. Anyone offering or performing home improvements here has to be registered with the Division of Consumer Affairs under N.J.S.A. 56:8-138, which has no dollar threshold, and 56:8-147(b) bars a municipality from issuing a construction permit to a contractor who is not registered. So ask for the registration number rather than the job title.
Roofing & Exteriors
Do I need a permit to replace my roof in New Jersey?+
Usually not, if it is just the covering on a detached one- or two-family home. N.J.A.C. 5:23-2.7(c)1x calls that ordinary maintenance — no permit, no inspection, no notice — and an attached row home or a three-family is outside the exemption from the start. It covers the covering only: the moment we replace decking or touch framing, 5:23-2.7(b)4 puts the job back under permit. The part nobody mentions is that no permit also means no town inspector ever looks at the work, so the contractor is the only check there is.
How much does a roof replacement cost in New Jersey?+
We do not publish a roof price here, because the number moves with things only a measurement settles: roof size, pitch and how cut up it is, how many old layers have to come off, decking rot that only shows after tear-off, material grade, access and permits. Our roof cost calculator carries market ranges by county for sanity-checking a bid you already have — those are estimates, not our quote. A real figure comes from a free on-site measurement, and we line-item it so you can compare it against another bid item by item.
Do I need a whole new roof, or can it be repaired?+
Almost any single failure can be repaired — the real question is whether repairing is the smart spend. A roof with years of life left and one localized failure, a flashing, a valley, a pipe boot, a run of nail pops, is an easy repair. A roof on its second or third layer, shedding granules across the whole field, with shingles that crack when walked, is a patch that buys months. We give you the cost and the years bought for each path on-site. If a small flashing fix gets you five more years we will say so, even though the tear-off is the bigger ticket for us.
Roof repair, and when it's the right call · What a free roof inspection covers
Can you put a new roof over the old shingles?+
Sometimes legally, usually not wisely. Under the NJ IRC (R908.4) you cannot add a layer where the roof already carries two, where the deck or existing covering is water-soaked or deteriorated, or over slate, clay or cement tile — two layers is the hard ceiling. Even where an overlay is allowed it buries deck rot instead of fixing it, hides the flashing, traps heat that shortens the new shingles' life, and adds roughly 200 to 250 pounds per square. We tear off to the bare deck, and on the rare roof where an overlay genuinely makes sense we say so and show you what you are giving up.
Is ice-and-water shield actually required on a New Jersey roof?+
In one county, strictly speaking. The model text of IRC R905.1.2 names no temperature; the 25°F figure is New Jersey's, added at adoption. New Jersey's amended Table R301.2 points to DCA Bulletin 07-3, which requires the barrier where the average daily January temperature is 25°F or less and states that for the State of New Jersey that area is Sussex County. So outside Sussex a cheaper bid can leave the membrane off and still pass. We install it on every roof anyway, because not required and not needed are different sentences — and it is a line you are free to strike.
Are you certified by the shingle manufacturer?+
We are a GAF Certified roofing contractor — the entry tier of GAF's certification ladder, listed in GAF's own contractor directory under our Garfield address, and our only manufacturer credential. Be clear on what it buys: it registers GAF's System Plus Limited Warranty, while the Silver Pledge and Golden Pledge sit above it on higher tiers whose requirements we have not met. We install Owens Corning and CertainTeed shingles too, but we are certified with GAF only — on one of those roofs you get the standard product warranty plus our own ten-year workmanship warranty, not an enhanced registered system.
What warranty comes with a new roof?+
Two, and they fail differently. The manufacturer's covers the shingle — a defect in the product, which is rare — and it only stands if the roof was installed to spec with balanced ventilation and code-grade underlayment; inadequate ventilation is one of the most common grounds a manufacturer cites for denying a claim, so it is a condition of the coverage, not an upgrade. Ours covers the hands that put it on: flashing, fasteners, seams and transitions. It runs ten years and transfers with the property. Ask every bidder for both in writing — under N.J.A.C. 13:45A-16.2 a warranty offered verbally has to appear in the contract anyway.
Will my homeowners insurance pay for a new roof?+
NJ policies generally cover sudden accidental damage — wind, hail, a tree strike — and generally not wear, age or deferred maintenance, and every denial turns on which of the two an adjuster thinks it is. On a replacement-cost policy the carrier pays actual cash value first and releases the withheld depreciation only after the work is finished and invoiced; an ACV-only policy never reimburses full replacement. N.J.A.C. 11:2-17.7 gives you dates to hold them to: investigation commenced within 10 working days, pay or deny within 30 calendar days of a properly executed proof of loss. We document the damage and stand on the roof next to your adjuster. We will not promise your claim gets approved — no roofer honestly can.
My insurer says my roof is too old to renew the policy. What can I do?+
There is no roof-age cutoff in New Jersey law and no state agency publishes one — it is an underwriting guideline your carrier chose. N.J.A.C. 11:1-20 sets the rules around it: a non-renewal notice has to arrive not more than 120 nor less than 30 days before the policy expires and has to state the factual basis, and your policy entitles you to the written underwriting guideline on request. Ask for it. Two things not to do: do not file a claim to solve an age problem, and do not assume a new roof guarantees renewal. It often helps. It is not a promise.
Is there any New Jersey program that helps pay for a roof?+
One that we can verify, and only in Bergen County. The county's Home Improvement Program names Roof, Leaders, Gutters among its eligible improvements for low- to moderate-income owner-occupants — up to $17,500 for a one-family home or condo interior and $25,000 for a two-family, interest free with no monthly payment. Read the structure before celebrating: it is not a rebate and not a grant. Nothing is due until the home is sold or title transfers, which makes it a lien rather than money off the job — good if you are staying put, worse if you are about to sell. We cannot bill against it or apply on your behalf; you apply to the county directly.
What is roof repair, and how is it different from a roof replacement?+
Roof repair fixes an isolated failure on a roof that still has life in it — a split pipe boot, a length of step or counter flashing, a valley, a run of backed-out fasteners, a few shingles a storm took. Replacement strips the covering to the deck and rebuilds the whole assembly. The dividing line is not age, it is whether the failure is in one place or everywhere: a roof with one bad detail and years of field left is an easy repair, while a roof shedding granules across every slope with shingles that crack when walked is a patch that buys months. New Jersey treats both the same way for permitting — N.J.A.C. 5:23-2.7(c)1x calls the repair or replacement of existing roof covering on a detached one- or two-family dwelling ordinary maintenance, so no permit, no inspection and no notice — unless the work touches decking or framing or adds a penetration, which puts it back under permit at 5:23-2.7(b)4. If a small flashing fix gets you five more years we will say so on site, even though the tear-off is the bigger ticket for us.
