Window Replacement & Installation — South Jersey, NJ

Window Replacement Contractor in South Jersey

Old windows cost you money every month — drafts in winter, heat gain in summer, and energy bills that don't reflect what you're actually using your HVAC for. Legacy Contracting installs replacement windows across South Jersey that seal properly, perform long-term, and actually look good doing it.

We work with homeowners in Camden, Gloucester, and Burlington counties. No subcontractors, no high-pressure sales process — just a straight conversation about what you need and a clean installation from a crew that's done this hundreds of times.

Window Types We Install

We install the full range of residential window styles — whatever fits your home's architecture, your energy goals, and your budget. Every window is installed with proper flashing, insulation, and trim so there's no air infiltration and no callbacks.

  • Double-hung windows — the most common replacement; tilt-in sashes for easy cleaning
  • Casement windows — crank-out style, excellent seal and ventilation
  • Sliding windows — great for wide openings and contemporary homes
  • Bay & bow windows — adds depth, light, and curb appeal
  • Picture windows — fixed pane, maximum light, zero drafts
  • Egress windows — basement bedroom code compliance
  • Storm windows & inserts — budget-friendly efficiency upgrade over existing frames

Energy Efficiency & Performance

In South Jersey, summers are humid and winters are cold enough to matter. The windows we install are selected for New Jersey's climate — double or triple-pane glass, low-E coatings, argon gas fill, and insulated frames that don't conduct cold the way aluminum does.

Most homeowners see a measurable drop in energy bills within the first year after a full window replacement. Beyond efficiency, well-sealed windows reduce outside noise, eliminate condensation on the glass, and stop the UV fading that damages flooring and furniture.

  • Energy Star certified options available
  • Low-E glass with argon fill — standard on most installs
  • Vinyl, fiberglass, and composite frame options
  • Sound-dampening glass for busy streets

Frequently Asked Questions — Window Replacement

How do I know if my windows need replacing?

+

Drafts around the frame, condensation between the panes, difficulty opening or closing, visible rot or warping, and noticeably higher energy bills are all signs it's time to replace. If your windows are original to a home built before 2000, they're almost certainly costing you money every month.

How long does a window replacement project take?

+

Most whole-home window replacement jobs take one to three days depending on the number of windows and any structural modifications required. Single-room or partial replacements are often done in a day.

Do window replacements require a permit in New Jersey?

+

Like-for-like window replacements in the same opening typically do not require a permit in New Jersey. If you're changing the size of an opening or adding a new window where there wasn't one, a permit is usually required. We handle that process when it applies.

Are there tax credits available for energy-efficient windows?

+

Yes. The federal Energy Efficient Home Improvement Credit (25C) covers up to 30% of the cost of qualifying Energy Star windows, up to $600 per year. We can identify which products qualify when you're selecting windows.

Do you serve my town in South Jersey?

+

We serve all of Camden, Gloucester, and Burlington counties — Cherry Hill, Moorestown, Mount Laurel, Haddonfield, Marlton, Voorhees, Medford, Washington Township, Sewell, Mullica Hill, Haddon Heights, Runnemede, Woolwich Township, and surrounding areas.

Well done guys. Thanks for the friendly service and saving not only my deck but my house. Would absolutely recommend Legacy to anyone looking for quality work done right.

Fabulous job. Very detail oriented and efficient. The crew was professional from start to finish and the final product exceeded expectations. I would not hesitate to recommend them.

Great work and the final product was beautiful. They communicated clearly throughout — we always knew what was happening and when to expect the crew.

Great service, super friendly. They treated my home like it was their own — that's exactly what you want from a contractor. I'll definitely use them for other jobs in the future.

Great group of people. Never had a bad experience. Hired them twice — both times the crew showed up on time, worked clean, and left the property in better shape than they found it.

Experience was refreshingly informal — the team kept things casual and clear. No sales pressure, no runaround. They quoted it, built it, and it looks exactly like we discussed.
