What We Do

Glass Installation

From a single broken sash on a Cape Cod in Toms River to a full curtain-wall reglaze on a Newark office tower, our glass installation crews handle every category and substrate. We measure, fabricate to spec, and install glass that meets the New Jersey Uniform Construction Code's safety glazing requirements (N.J.A.C. 5:23) and the relevant ASTM standards for the application.

Glass installation isn't a single skill — it's a portfolio of techniques that change with every substrate, frame system, and code requirement. A frameless shower in a Bergen County master bath has nothing in common with a storefront reglaze in downtown New Brunswick or a historic wood sash restoration in Cape May. We do all of it because we've trained crews on each system and stock the fabrication equipment to match.

We work across all of New Jersey: from Atlantic, Cape May, and Ocean Counties down the shore, to Bergen, Hudson, and Passaic in the north, through Mercer, Middlesex, and Monmouth in the middle, and out to Sussex, Warren, and Hunterdon in the northwest. Coastal jobs use marine-grade hardware to survive salt air; pre-war homes in Princeton or Madison get historically appropriate divided-light glass; commercial jobs near Newark Liberty get acoustic IGUs to deal with flight-path noise.

What we install

Single-pane annealed glass for non-hazardous interior cabinet doors, picture frames, and shelving. Tempered safety glass (ANSI Z97.1) for shower enclosures, glass railings, sliding doors, and any pane within 24 inches of a doorway or 18 inches off the floor — required by New Jersey's adoption of the IRC's safety glazing rules.

Laminated glass with PVB or SentryGlas interlayer for security glazing, hurricane-rated openings on coastal properties, sound attenuation near rail corridors and Newark/Teterboro flight paths, and any overhead application like skylights and canopies.

Insulated glass units (IGU) — dual or triple pane with argon or krypton gas fill and Low-E coatings. Required for new construction and most replacement work to meet NJ's adopted 2021 IECC residential energy code (R402.1.3 prescriptive U-factor of 0.30 for our climate zone).

Custom-shape and oversized glass for picture windows, transoms, sidelights, store displays, and architectural features. We fabricate up to 96" x 130" in-house and broker larger panels through our IGU partners.

How NJ code shapes our work

New Jersey adopts the International Residential Code (IRC) and International Building Code (IBC) with state-specific amendments under N.J.A.C. 5:23. For glass that means: every pane in a door must be safety glazed; bathroom windows below 60" from the floor must be tempered; shower enclosures must be tempered or laminated; and railings must use heat-strengthened laminated glass per IBC 2407.

Energy compliance: most replacement projects require Low-E IGU with U-factor ≤ 0.30 and SHGC ≤ 0.40 for our climate zone (Zone 4 or 5 depending on county). We use NFRC-labeled product so the inspector can verify on site.

Historic districts: Princeton, Madison, Cape May, Lambertville, Frenchtown, and many others have certificates-of-appropriateness review for visible window changes. We coordinate with the local Historic Preservation Commission and source replicate divided-light or restoration glass when needed.

Residential vs commercial differences

Residential glass installation usually means single openings, framed sashes, and either a homeowner-driven aesthetic decision or an emergency repair. Average lead time from measurement to installed glass is 5-10 business days for standard IGUs and 1-3 days for stocked tempered shower glass.

Commercial work involves curtain-wall systems (Kawneer, YKK AP, EFCO), aluminum storefront framing (1-3/4" or 2" depths), and often after-hours scheduling to keep tenants operating. We schedule night and weekend reglazes for retail and office tenants in Newark, Jersey City, Hoboken, and Princeton.

Our Process

1
Site visit and measure
We come on-site within 1-2 business days for residential, same-day for commercial emergencies. Every opening is measured at three points (top, middle, bottom + height left/right) since few openings are square. For IGUs we record glazing pocket depth so the new unit fits the spacer.
2
Spec and quote
Within 24 hours you receive a written quote listing the exact glass make-up (e.g., '1/4" tempered low-E #2, 1/2" argon, 1/4" annealed clear'), frame work needed, and total turnaround. We list the product NFRC sticker so you can verify code compliance.
3
Fabrication
Tempered, cut-to-size annealed, and stocked shapes are fabricated in our shop. Custom IGUs go through our manufacturer partners with 5-10 day production. We track production daily and update you mid-week.
4
Install
Crew arrives in branded vans with complete tool kits, drop cloths, and dust containment. Old glazing is removed cleanly, the frame is inspected for rot or corrosion (we flag and quote any repair needed before reglaze), and the new unit is set with appropriate setting blocks, glazing tape, and sealant.
5
Cleanup and walkthrough
All shards and packaging leave with us. We walk the homeowner or facility manager through the install, verify smooth operation, hand over warranty paperwork (lifetime workmanship + manufacturer IGU warranty), and label the IGU with installation date for future reference.

Materials We Use

Tempered safety glass

Heat-treated to be ~4× stronger than annealed. Breaks into small dull pebbles instead of shards. Required by code in shower enclosures, glass doors, sidelights, low-mounted windows, and railings.

Laminated safety glass

Two glass layers bonded with a PVB or ionoplast interlayer. Holds together when cracked — required for overhead applications, security glazing, and hurricane zones along the Jersey Shore.

Insulated glass unit (IGU)

Two or three glass panes separated by a sealed spacer filled with argon or krypton. Low-E coating on surface 2 or 3 reduces heat transfer. The default for any energy-code-regulated opening.

Low-iron (Starphire) glass

Specialty glass with reduced iron content for true clarity — no green tint. Used in custom shower enclosures, retail display cases, and aquarium glass where the green edge of standard glass is visible.

Acoustic laminated

Laminated glass with an acoustic-grade PVB interlayer that delivers STC ratings up to 50+. We install these regularly on properties under the Newark Liberty, Teterboro, and Atlantic City flight paths.

Frequently Asked Questions

About Glass Installation in NJ

What drives the cost of glass installation in NJ?+

Cost depends on the glass type (annealed vs tempered vs laminated), the glazing spec (single-pane vs IGU, Low-E coating, gas fill, warm-edge spacer), the opening size and shape, and the access requirements. Residential single-pane replacement is the cheapest scope; tempered safety glass for showers and doors costs more per square foot because of the heat-treating; IGU replacement varies widely with sash size and coating package. Commercial storefront reglaze is quoted per opening based on frame system and access requirements. Every quote we issue includes a written breakdown — no flat-rate guesses, and we don't publish pricing because every job is custom-scoped.

What glass is required by code in NJ for showers and doors?+

New Jersey adopts the International Residential Code Section R308 (safety glazing). Any glass within a shower or tub enclosure, in or adjacent to a door (within 24 inches of the door's vertical edge), within 18 inches of the floor, or in a window where the bottom edge is less than 18 inches off the floor and the top edge is more than 36 inches above the floor must be tempered or laminated. Glass railings on stairs and balconies require heat-strengthened laminated per IBC 2407.

How long does it take to get replacement glass in NJ?+

Stocked tempered shower glass: 1-3 business days. Standard IGU sashes: 5-10 business days through our manufacturer partners. Custom-shape, oversized, or specialty glass (Starphire, hurricane-rated, decorative): 2-3 weeks. Emergency board-up and weather-tight covering is available within 2-4 hours for broken windows on residential or commercial properties anywhere in our service area.

Do you serve all of New Jersey?+

Yes — we install glass in all 21 NJ counties, from Cape May and Atlantic in the south to Sussex and Warren in the north. Travel charges may apply for jobs more than 60 miles from our Garfield, NJ shop, but we don't decline jobs based on geography.

Can you replace foggy double-pane glass without replacing the whole window?+

Yes. The fog inside a double-pane window means the IGU's perimeter seal has failed and gas has leaked out. As long as the sash and frame are sound, we replace just the IGU and leave your existing window in place. This costs roughly 30-50% of full window replacement and takes a single visit once the new IGU is fabricated. See our dedicated double-pane resealing service for detail.

Do you handle historic district glass replacement?+

Yes. We've worked in Princeton, Madison, Cape May, Lambertville, Frenchtown, and other NJ historic districts. We coordinate with the local Historic Preservation Commission, source true-divided-light glass, restoration glass with period-appropriate waviness, and where needed match original putty glazing detail rather than modern glazing tape.

Are you licensed and insured to install glass in NJ?+

Yes. We carry an active New Jersey Home Improvement Contractor (NJHIC) registration, full general liability insurance, and workers' compensation. Documents are available on request and we provide them automatically with every written quote.
