Before listing a New Jersey house, fix the things a buyer's inspector will write up in bold: active leaks, a roof at the end of its life, a water heater or furnace past 15 years, an outdated or recalled electrical panel, missing GFCI outlets, bad grading and gutters that dump water at the foundation, and a sewer line that has never been scoped.

Before listing a New Jersey house, fix the things a buyer's inspector will write up in bold: active leaks, a roof at the end of its life, a water heater or furnace past 15 years, an outdated or recalled electrical panel, missing GFCI outlets, bad grading and gutters that dump water at the foundation, and a sewer line that has never been scoped. Every New Jersey sale also needs a smoke detector, carbon monoxide alarm and fire extinguisher certificate from the town before closing.
Here is the list in the order that matters, with 2026 prices and a plain answer on what pays back.
The certificate every NJ sale needs
New Jersey requires a Certificate of Smoke Detector, Carbon Monoxide Alarm and Portable Fire Extinguisher Compliance before a home changes hands. Your town's fire official inspects for smoke alarms on every level and outside sleeping areas (10-year sealed battery units are required where they are not hardwired), a CO alarm within 10 feet of bedrooms, and a 2A:10B:C fire extinguisher, usually in the kitchen. The fee is small, the inspection takes 15 minutes, and a fail delays the closing. We bring the right alarms and extinguisher and mount them in an hour.
What inspectors flag most, and what it costs to fix
| Item | What the inspector writes | Fix before listing (NJ 2026) |
|---|---|---|
| Roof at 20+ years, curling or missing shingles | 'Roof at end of service life'; buyers ask for $10K+ credits | Repair $450 – $2,500; replacement $9.5K – $45K+ |
| Water heater over 12 years | 'Beyond typical service life' | Replace $1.8K – $4.5K |
| Furnace or boiler over 20 years, cracked heat exchanger | 'Recommend evaluation by HVAC contractor' | Replace $3.8K – $12K |
| Federal Pacific, Zinsco or Sylvania panel, or a fuse box | 'Known safety hazard, recommend replacement' | New 200A panel $1.8K – $2.8K; service upgrade $3.5K – $6.6K |
| Missing GFCI outlets in kitchen, baths, garage, outside | Cheap fix that shows up on every report | $180 – $650 for a house |
| Double-tapped breakers, open junction boxes, reversed polarity | 'Deficiencies noted by licensed electrician' | $150 – $500 |
| Grading toward the house, downspouts dumping at the foundation | 'Potential for water intrusion' | Extensions $150 – $400; regrade $800 – $3K |
| Wet basement, efflorescence, sump with no cover or backup | 'Evidence of moisture' | Sump and backup $900 – $3.5K; waterproofing $3K – $15K |
| Sewer line never scoped (pre-1975 house) | Buyer's sewer scope finds roots or a break, deal stalls | Scope it first $275 – $550; repair only if needed |
| Dripping faucets, running toilets, slow drains | Small, but they make the whole house look neglected | $150 – $450 each |
| Rotted trim, peeling paint, cracked caulk | 'Deferred maintenance' | Handyman half day $450 – $600 |
| Missing handrails, loose deck boards, deck not flashed to house | Safety items; deck ledger is a big one | $250 – $2,500 |
Fix it, or price it in? The honest math
Fix anything under about $2,000 that shows up as a safety item or a leak. Buyers do not discount a $600 problem by $600; they discount it by $3,000 and start wondering what else is wrong.
For the big items, roof, furnace, panel, you have two good choices. Replace it and market the house as updated, which usually returns most of the cost in the sale price and a faster close. Or get a written, itemized quote from us now and hand it to buyers, so the negotiation is about a real number instead of a guess. What does not work is ignoring it; the inspector finds it every time.
Skip the full kitchen or bath remodel before selling. You will not get the money back. Paint, lighting, hardware, a new faucet and a deep clean do more per dollar.
The pre-listing inspection: worth it in NJ
Paying $400 to $600 for your own inspection before you list, including a sewer scope on any house built before 1975, lets you fix things on your schedule with your contractor at normal prices, instead of in a panic ten days before closing with the buyer's contractor pricing the credit. It also removes the biggest deal-killer in New Jersey sales: the surprise.

Questions people ask next
What repairs are required to sell a house in New Jersey?
The only state requirement is the smoke detector, carbon monoxide alarm and fire extinguisher certificate from your town. Everything else is negotiated, but safety items and active leaks are the ones buyers walk away from.
Should I replace my roof before selling?
If it is at the end of its life, either replace it or get a written quote and price it into the deal. A 25-year-old roof is the most common reason buyers ask for a large credit or back out after inspection.
Do I need to fix everything on the inspection report?
No. Fix safety items, leaks and anything cheap. Big-ticket items can be replaced or credited. Cosmetic items rarely matter as much as sellers think.
Is a Federal Pacific panel a deal breaker in NJ?
It is close to one. Most inspectors flag it as a known hazard, some insurers will not write a policy with one, and buyers ask for a replacement. Swapping it for a new 200-amp panel is $1,800 to $2,800 and takes a day.
Should I get a sewer scope before selling?
Yes, on any house built before about 1975 or with big trees near the line. It costs $275 to $550, and finding roots or a break on your terms is far better than finding it in the buyer's report.
