Chimney Repair
Watertight from the cap down.
Landstar handles crown repair, flashing replacement, masonry repointing, waterproofing, and liner installs, short-scope chimney work that fixes leaks without a full rebuild. Licensed and insured.
Landstar repairs chimneys across New Jersey, repointing failed mortar joints, sealing and re-flashing against leaks, and replacing cracked crowns and rusted caps, so you can avoid a full rebuild when the brick below is still sound. Most New Jersey chimney repairs run roughly $500 to $3,000; a new crown or stainless cap is typically $300 to $1,500.
Most chimney calls don’t need a rebuild, they need a repair. Crown cracked through, flashing pulling away from the brick, mortar joints opening up past a quarter inch. We see all of it, and most of it gets fixed in two or three days.
The leak that shows up six feet from the chimney on a bedroom ceiling almost always starts at one of three places: the crown, the flashing, or the masonry above the roofline. We inspect all three on every visit and tell you which one is the actual problem. No upselling a rebuild when a crown pour will do it.
For deeper structural damage where the brick above the roofline is failing, see our chimney rebuild page. For routine cleaning and Level 1 safety inspections, see chimney sweep.

Chimney Repair questions.
- How much does chimney repair cost in New Jersey?
- Most New Jersey chimney repairs run roughly $500 to $3,000, depending on the work: repointing failed mortar joints, a new poured crown, new flashing, or a stainless cap typically fall in that range, and a crown or cap on its own is often $300 to $1,500. A full rebuild costs more. Landstar tells you which one your chimney actually needs after a free inspection.
- Repair or rebuild, what's the threshold?
- Repair territory is a cracked crown, failed flashing, or mortar joints needing tuck-pointing. Rebuild territory is brick spalling above the roofline, mortar joints gone past a quarter inch on more than half the stack, or a crown cracked through with daylight visible from the firebox. The Landstar chimney-rebuild page covers the rebuild decision criteria in full.
- Do you replace the liner too?
- Yes. If you're burning wood or running a high-efficiency gas appliance, the original clay liner is often cracked or undersized. We install UL-listed stainless steel liners sized to the appliance manufacturer's spec.
- What's the warranty on a chimney repair?
- Workmanship is warranted by Landstar, and the stainless liner and caps carry their own manufacturer coverage. All warranties are project-specific and provided in writing with the contract.
- Will my fireplace still work the same after the work?
- Better. A properly sized liner improves draft, reduces creosote buildup, and brings the chimney up to current code. We do a draft test before we leave.
