Insulation-first home performance
Jersey Home Performance helps New Jersey homeowners get more from their homes — through professional insulation, air sealing, and window & door upgrades backed by available utility incentives and federal tax credits.
Licensed & insured in New Jersey · Serving Northern & Central NJ
What we do
Most older NJ homes lose a significant amount of heat and cooling through the attic, walls, basement, and around windows and doors. We identify where that is happening, recommend the right upgrades, and handle the installation.
Quick answer
Many comfort issues come from air leakage and missing insulation rather than the visible parts of the envelope alone. Fixing the hidden problems first often delivers better results at lower cost than jumping straight to window replacement.
That does not mean windows don't matter — it means there is usually a smarter order to address things.
See what is happening
Most homeowners feel the symptoms before they understand the cause. These visuals walk through where homes lose energy, how the envelope gets fixed, and why the right order of operations can improve comfort before you spend money in the wrong place.
Where homes leak
Attics, recessed lights, rim joists, basement transitions, window gaps, and wall penetrations all add up. The result is drafts, uneven temperatures, and HVAC systems working harder than they should.
What changes
The goal is not just adding material. It is tightening the envelope, reducing uncontrolled airflow, and helping the whole home hold a more stable temperature.
Why it pays off
When the envelope performs better, rooms feel more even, drafts calm down, and your heating and cooling system is not fighting the house all day.
Start with an assessment
The point of a home performance assessment is to explain what is happening in your specific home, prioritize the biggest wins, and avoid expensive upgrades that do less than expected.

Why Jersey Home Performance
We are not a jack-of-all-trades GC. Home performance and envelope upgrades are our focus — more expertise, better outcomes.
PSEG and federal tax credits can make upgrades significantly more affordable. We help you understand what may apply before you spend anything.
We look at the whole envelope — attic, walls, basement, windows, doors — and recommend what actually moves the needle for your home.
Clean installation by people who communicate clearly, show up on time, and do not leave a mess. That is not the standard. It should be.
We know NJ housing stock — colonials, split-levels, cape cods, and ranchers with the same drafts, cold floors, and inefficient attics.

FAQ
The most common signs are uneven temperatures between rooms or floors, drafts near exterior walls or windows, high heating and cooling bills, or a home that feels cold in winter despite running the heat. Many older New Jersey homes were built before modern energy codes and are significantly under-insulated. A home performance assessment is the most reliable way to know for sure.
Yes — often more than adding more insulation alone. Insulation slows heat transfer, but air sealing stops air from physically moving in and out through gaps and cracks. In most older homes, both matter. We typically recommend doing air sealing before or alongside insulation upgrades.
For most homes, insulation and air sealing deliver a better return than window replacement alone. Windows do matter — especially older single-pane or poorly sealed units — but they are rarely the highest-priority upgrade. We give you an honest assessment of what will make the biggest difference.
PSEG offers utility rebate programs for qualifying energy improvements, and the federal Inflation Reduction Act provides tax credits for insulation, air sealing, windows, doors, and certain equipment. Amounts and eligibility change, so we discuss current programs with every homeowner.
We serve Northern and Central New Jersey, with a focus on Essex, Morris, and Union counties. Our core service area includes Montclair, Maplewood, South Orange, Millburn, Summit, Livingston, West Orange, and Morristown — plus surrounding communities.
It is a professional evaluation of how your home performs — where it loses energy, what causes comfort problems, and which upgrades are most likely to make a real difference. It is not a sales visit. It gives you a clear picture before you commit to anything.
Yes. Window and door upgrades are part of our whole-home envelope approach. We offer them as a meaningful value-add, especially for homeowners who want to address multiple performance issues in one project.
