You’re not lighting fires wondering if tonight’s the night something goes wrong. You’re not stressing about water stains spreading across your ceiling every time it rains. And you’re definitely not paying for a full chimney replacement when a solid repair would’ve handled it.
That’s what happens when your chimney actually works. The draft pulls smoke up and out like it should. Your fireplace heats the room instead of filling it with soot. Water stays outside where it belongs.
Florham Park winters are cold, and your chimney takes a beating from freeze-thaw cycles, ice storms, and wind-driven rain. Cracks in the crown let moisture in. Mortar joints break down. Flashing fails. These aren’t cosmetic issues—they’re structural problems that get worse fast and cost more the longer you wait.
We fix chimney leaks, cracked crowns, damaged flue liners, and deteriorating brick before they turn into expensive emergencies. You get a fireplace you can actually use and a chimney that protects your home instead of threatening it.
Proline Construction has spent over a decade working on homes in Florham Park and across Morris County. We’re certified masonry contractors who know how New Jersey weather tears chimneys apart—and exactly how to fix them so they last.
We’re not a national franchise or a referral service. We’re local contractors who show up, do the work ourselves, and stand behind it. Our team handles everything from minor mortar repairs to full chimney rebuilds, and we’ve seen every type of damage these winters can cause.
You’re hiring people who’ve worked on hundreds of chimneys in this area. We know the building codes, the common failure points in older homes, and what actually holds up long-term in this climate. That experience matters when you’re trusting someone to work on a structure that’s keeping smoke and carbon monoxide out of your house.
First, we come out and inspect your chimney from top to bottom. That means getting on the roof, checking the crown and cap, examining the flashing, and looking inside the flue. We’re checking for cracks, water damage, creosote buildup, structural issues—anything that’s causing problems or about to.
Then we walk you through what we found. No jargon, no upselling. Just a clear explanation of what’s wrong, what needs to be fixed now, and what can wait. You get a written estimate that breaks down the work and the cost so you can make an informed decision.
Once you approve the work, we schedule it and show up on time. Most chimney repairs take one to three days depending on the scope. We handle everything—masonry work, flashing replacement, crown repairs, liner installation, waterproofing. When we’re done, we clean up completely and walk you through what we did.
You’re not guessing whether your chimney is safe. You know exactly what condition it’s in and what was done to fix it.

Chimney crown repair is one of the most common jobs we do in Florham Park. That concrete cap at the top of your chimney cracks from freeze-thaw cycles, and once water gets in, it damages everything below. We rebuild crowns with proper slope and overhang so water runs off instead of pooling.
Tuckpointing and brick repair come next. Mortar joints deteriorate faster than the brick itself, especially on the side of your chimney that takes the most weather. We remove the damaged mortar and repoint the joints so your chimney is structurally sound again. If bricks are cracked or spalling, we replace them.
Chimney leak fixing usually involves flashing—the metal seal where your chimney meets the roof. When flashing fails, water pours into your attic and down your walls. We remove the old flashing, install new corrosion-resistant material, and seal it properly so it actually keeps water out.
Flue liner repair or replacement is critical for safety. A damaged liner lets heat and gases escape into your walls, which is a fire hazard and a carbon monoxide risk. We install stainless steel liners that meet code and protect your home for decades.
We also handle chimney cap installation, waterproofing, and full chimney rebuilds when the damage is too extensive to repair. Every job includes a thorough cleaning because you can’t assess or fix a chimney properly when it’s full of soot and creosote.
If the damage is isolated—a cracked crown, deteriorating mortar joints, failed flashing—repair makes sense. These are fixable problems that don’t require tearing down the entire structure. Most chimneys we see in Florham Park fall into this category.
Replacement becomes necessary when the structural integrity is compromised throughout. That means severe brick damage on multiple sides, a leaning chimney, or extensive interior deterioration that’s unsafe to patch. We’ll tell you honestly which situation you’re dealing with.
The cost difference is significant. A typical repair runs a few hundred to a couple thousand dollars depending on the scope. A full rebuild starts around $8,000 to $15,000 or more. We’re not going to recommend replacement if a solid repair will give you another 20 years of safe use.
Once a year, ideally in late summer or early fall before you start using your fireplace. That gives you time to handle any repairs before heating season hits.
Chimney sweep companies near me will tell you the same thing—annual inspections catch problems early. Creosote builds up every time you burn wood, and it’s flammable. A quarter inch of buildup is enough to cause a chimney fire. Regular cleaning removes that risk.
The inspection part matters just as much as the cleaning. We’re looking for cracks, water damage, animal nests, and structural issues that you can’t see from the ground. Catching a small crack in the crown now saves you from major water damage repairs later. If you use your fireplace heavily or burn a lot of green wood, you might need cleaning twice a year.
Most chimney leaks in Florham Park come from failed flashing, cracked crowns, or missing chimney caps. Flashing is the metal seal where your chimney meets the roof, and it takes a beating from our weather. When it corrodes or pulls away, water runs straight into your attic.
Cracked crowns are just as common. That concrete top is supposed to shed water, but freeze-thaw cycles crack it. Once water gets into those cracks, it seeps down into the brick and mortar, causing interior damage and staining.
We fix leaks by addressing the source. If it’s flashing, we remove the old material, install new step flashing and counter flashing, and seal everything properly. For crown damage, we rebuild the crown with the right slope and overhang. If your cap is missing or damaged, we install a new one with a spark arrestor and animal guard. Waterproofing the brick is the final step—it lets the chimney breathe while keeping water out.
We repair the sections that need it. If your crown is cracked but the rest of the chimney is solid, we fix the crown. If the top ten courses of brick are damaged but everything below is fine, we rebuild that section.
Partial repairs are common and completely appropriate when the damage is localized. There’s no reason to tear down and rebuild an entire chimney when the problem is isolated to one area. That’s a waste of your money and our time.
The exception is when we find multiple failure points or structural instability. If the damage is widespread—deteriorated mortar throughout, severe brick spalling on multiple sides, a compromised foundation—then a more extensive repair or rebuild makes sense. We assess the entire structure during inspection and recommend the most cost-effective approach that keeps your chimney safe and functional.
Most repairs take one to three days depending on what needs to be done. A crown repair or repointing job might be a day or two. Flashing replacement, liner installation, or more extensive masonry work takes longer.
Cost depends entirely on the scope of damage. Minor repairs like replacing a chimney cap or fixing small sections of mortar might run $300 to $800. Crown rebuilds typically cost $1,000 to $2,500. Flashing replacement runs $800 to $1,500. Flue liner installation is $1,500 to $4,000 depending on the height and type of liner.
Extensive brick repair or partial rebuilds cost more—anywhere from $3,000 to $8,000 depending on how much of the chimney needs work. We give you a detailed written estimate before starting so you know exactly what you’re paying for. No surprises, no hidden fees. The price we quote is the price you pay unless we uncover additional damage once we start the work—and we’ll discuss that with you before proceeding.
Yes. If your chimney is actively leaking, damaged from a storm, or creating a safety hazard, call us. We prioritize emergency situations because we know water damage and structural issues get worse by the hour.
Emergency repairs might mean temporarily sealing a leak, stabilizing damaged brick, or making your chimney safe to use until we can schedule the full repair. We’re not going to leave you with water pouring into your house or a chimney that’s unsafe to operate.
That said, most chimney problems develop slowly. The crack in your crown didn’t appear overnight—it’s been growing for months or years. The earlier you catch these issues, the less they cost to fix and the less likely you are to need emergency service. If you’re seeing water stains, noticing pieces of brick or mortar in your fireplace, or smelling smoke inside your house, don’t wait. Those are signs of problems that need attention now, not next season.
