Replacement Windows in New Jersey

New Jersey homes get worked harder than almost any housing stock in the country, Atlantic coastal storms in the south, lake-effect snow in the northwest, 90°F-plus summers, and some of the highest property tax assessments in the U.S. Window quality shows up in every one of those: energy bills, storm performance, home value at resale.

Thompson Creek manufactures replacement windows in Maryland and installs them across South Jersey, including Cherry Hill, Mount Laurel, Marlton, Burlington, Medford, Sicklerville, and Trenton. Every window is built to NJ’s 2021 IECC energy code and backed by our 50-Year No-Hassle Warranty.

Custom Replacement Windows for New Jersey Homes

Thompson Creek installs custom replacement windows across New Jersey, including Cherry Hill, Trenton, Mount Laurel, Marlton, Burlington, Medford, and Sicklerville. Every window is Maryland-manufactured, built to NJ’s 2021 IECC code thresholds, and installed by our own crews under a 50-Year No-Hassle Warranty.

Engineered for New Jersey’s 2021 IECC Energy Code

New Jersey adopted the 2021 International Energy Conservation Code (IECC) in September 2023, one of the strictest residential energy codes in the Mid-Atlantic. The code requires U-factor 0.30 or lower and SHGC 0.40 or lower for replacement windows in NJ Climate Zone 4 (most of the state).

Our standard double-pane vinyl windows come in at U-factor 0.28 and SHGC 0.30, already below code minimum, with substantial headroom for the next code revision.

Built for Coastal and Inland New Jersey Both

South Jersey shore towns (Cape May, Atlantic City, Brigantine, Long Beach Island) need DP50+ wind ratings and salt-air-resistant hardware. Inland NJ (Princeton, Marlton, Lawrenceville) needs maximum thermal performance for harsh winters.

Thompson Creek offers both coastal and inland configurations from the same product line, same warranty, same install crew, different glass and hardware packages calibrated to your exposure.

Why New Jersey Homeowners Choose Thompson Creek

We Manufacture What We Install, Maryland to NJ

Our windows are made at our Upper Marlboro, MD facility. South Jersey is closer to our factory than half of Maryland is, Cherry Hill is 130 miles from the factory, vs. Salisbury, MD at 150 miles.

The vertical integration means premium-grade product at a fair installed price, with one company handling sales, manufacturing, installation, and warranty service.

50-Year No-Hassle Warranty That Transfers

NJ property turnover rates are 8% to 12% annually in most counties. Our 50-Year No-Hassle Warranty transfers to subsequent homeowners, which protects resale value in markets where buyers’ inspectors flag aging windows.

The warranty covers seal failure, hardware corrosion, frame distortion, and glass breakage, no proration, no exclusions for normal use.

20,000+ Five-Star Reviews Across the Mid-Atlantic

Thompson Creek has installed windows across NJ, DE, MD, VA, DC, and PA since 1980. Our review volume reflects scale; our consistent 4.5+ star rating reflects what we actually deliver on installs.

New Jersey Window Replacement: What to Expect

Permits and the NJ Uniform Construction Code

New Jersey requires a Uniform Construction Code (UCC) building permit for every window replacement, even like-for-like swaps. Permits are issued by the local construction office in each municipality.

Thompson Creek pulls permits as part of the project, no homeowner hassle. For homes in NJ historic districts (Cape May, Princeton, Trenton’s Mill Hill), we also handle Historic Preservation Commission review.

NJ Climate Zones and Window Selection

Most of New Jersey is in IECC Climate Zone 4, with the far northwest corner (Sussex County) in Climate Zone 5. Climate Zone 4 calls for balanced U-factor and SHGC; Climate Zone 5 prioritizes the lowest possible U-factor.

Coastal NJ from Cape May up through Sandy Hook has additional wind load and impact considerations under FBC-derived state amendments.

Our New Jersey Window Replacement Process

Step 1, In-Home Consultation

A Thompson Creek consultant visits your NJ home, measures every opening, and walks you through frame materials, glass packages, and grid options. Free, no obligation, no high-pressure tactics.

For coastal homes (Brigantine, Long Beach Island, Cape May), we assess exposure category and wind zone before recommending a glass package.

Step 2, Custom Manufacturing in Maryland

Once your order is confirmed, our Maryland factory builds your windows to the exact dimensions of your NJ home. Lead time: 4 to 6 weeks for standard products, 5 to 7 weeks for coastal package, 6 to 8 weeks for historic-profile orders.

Step 3, Single-Day Installation

Most NJ home installations are completed in one day for projects up to 12 windows. Our crews are Thompson Creek W-2 employees, trained on our complete install spec.

Frequently Asked Questions About Window Replacement in New Jersey

Do you need a permit to replace windows in NJ?

Yes, New Jersey’s Uniform Construction Code (UCC) requires a permit for window replacement in every municipality, including in-kind replacements. Permits are issued by the local construction office (CO) in each town.

Thompson Creek pulls every permit as part of the project. For historic district homes, we also coordinate Historic Preservation Commission review where required.

Are coastal NJ homes required to use impact-rated windows?

NJ coastal building code requires impact-rated windows or shutters in designated wind-borne debris zones, which include parts of Cape May County, Atlantic County, and Ocean County. Outside those zones, impact glass is optional but strongly recommended for oceanfront and bayfront exposures.

Inland NJ (Cherry Hill, Mount Laurel, Trenton) doesn’t require impact glass under code.

How long does the full NJ window replacement project take?

Plan on 6 to 8 weeks from signed contract to installed windows: 4 to 6 weeks for custom manufacturing plus permit processing and the installation day. Coastal and historic-profile orders add 1 to 2 weeks for specialty production.

NJ permits typically process in 2 to 4 weeks; we submit early so it runs in parallel with manufacturing.
