You light your fireplace without worrying if smoke will back up into your living room. You stop seeing water stains on your ceiling after every rainstorm. Your chimney actually does its job—pulling smoke out, keeping carbon monoxide away from your family, and holding up through another freeze-thaw cycle without crumbling apart.
That’s what happens when the repair is done right. No more wondering if you’re one cold night away from a chimney fire. No more calling someone back to fix what should’ve been handled the first time.
Most chimney problems in Roxbury don’t announce themselves until it’s too late. A small crack in the crown lets water in. That water freezes, expands, and turns into a $3,000 problem by spring. We catch that stuff early, fix it correctly, and give you one less thing to worry about when the temperature drops.
Proline Construction has been working on homes in Morris County long enough to know what breaks, why it breaks, and how to fix it so it doesn’t break again next winter. We’re not a franchise or a call center—we’re local contractors who live and work in the same area you do.
Most of the chimneys we repair were built in the ’60s and ’70s, back when homes in Roxbury were going up fast. That means a lot of brick and mortar that’s been through 50+ freeze-thaw cycles. We know how those chimneys age, where they fail first, and what it takes to bring them back.
You’ll work with certified contractors who show up on time, assess the damage honestly, and explain what needs to happen without the runaround. We give you a free estimate based on what’s actually wrong—not what we wish we could sell you.
First, we come out and inspect your chimney from top to bottom. That means getting on the roof, checking the crown and cap, looking at the flashing, and examining the brickwork and mortar joints. We also inspect the flue liner and check for creosote buildup or blockages that could cause problems when you use your fireplace.
Once we know what’s wrong, we walk you through it. We’ll show you photos if needed, explain what’s causing the issue, and tell you what happens if it’s not fixed. Then we give you a written estimate that breaks down the work and the cost—no surprises, no upselling.
When we do the repair, we use materials that match your existing chimney and hold up to New Jersey weather. If it’s a brick chimney repair, we match the mortar and brick as closely as possible. If it’s a chimney leak, we address the root cause—whether that’s damaged flashing, a cracked crown, or failing mortar joints. The job gets done right, cleaned up completely, and you’re back to using your fireplace safely.

We handle chimney crown repair, which is critical in Roxbury because that’s where most water intrusion starts. A cracked or deteriorating crown lets moisture seep into your chimney, causing freeze-thaw damage that gets worse every winter. We rebuild or resurface crowns using weather-resistant materials designed for Morris County’s climate.
Chimney flashing repair is another common job here. Flashing is what seals the gap between your chimney and your roof, and when it fails, water pours into your attic and down your walls. We remove old, corroded flashing and install new material that’s properly sealed and secured.
Brick and mortar work is something we do constantly. Older chimneys lose mortar over time, especially on the side that faces prevailing winds and weather. We repoint those joints, replace damaged bricks, and restore structural integrity so your chimney doesn’t lean, crack, or collapse. If you need a full chimney installation or rebuild, we handle that too—from foundation to cap.
We also coordinate with chimney sweep companies when needed, especially if there’s heavy creosote buildup or an obstruction we find during inspection. Clean chimneys perform better and last longer, and we make sure yours is in good shape before we close out the job.
It depends on what’s broken. Small repairs like repointing a few mortar joints or patching a minor crown crack usually run between $400 and $800. Chimney flashing repair typically costs $600 to $1,200 depending on the size of your chimney and how much flashing needs replacement.
If you’re dealing with a chimney leak that’s caused structural damage, or if large sections of brick need replacement, you’re looking at $1,500 to $3,500 or more. A full chimney rebuild—which is rare but sometimes necessary on older Roxbury homes—can run $5,000 to $10,000 depending on height and materials.
We give you a free estimate after inspecting your chimney, so you’ll know exactly what the job costs before we start. No hidden fees, no change orders unless you ask us to do additional work.
If you’re seeing water stains on your ceiling near the chimney, or if you notice pieces of brick or mortar in your fireplace, that’s a repair issue—not something a chimney sweep can fix. Same goes for visible cracks in the chimney crown, gaps in the flashing, or bricks that are crumbling or pulling away from the structure.
Cleaning is what you need if your fireplace smokes back into the room, if you smell a strong odor when it’s not in use, or if it’s been more than a year since your last chimney sweep. Creosote buildup is a fire hazard, and blockages from animals or debris will keep your chimney from drafting properly.
Sometimes you need both. We’ll inspect your chimney and tell you what’s a structural problem and what’s a maintenance issue. If you need a cleaning, we’ll let you know—but we’re not going to sell you a repair you don’t need just because we’re already there.
Not if the crack is in the flue liner or if it’s allowing smoke or gases to escape into your home. Even a small crack in the liner can let carbon monoxide seep into your living space, and that’s not something you want to gamble with. If the crack is only in the exterior brick or crown and the flue is intact, you might be okay for a short time—but it’s going to get worse.
Freeze-thaw cycles in Roxbury make small cracks bigger. Water gets in, freezes, expands, and breaks the surrounding material. What starts as a hairline crack in November can turn into a chunk of missing masonry by March.
The safest move is to have it inspected before you use your fireplace. We’ll tell you if it’s safe to operate or if it needs immediate repair. If it’s a quick fix, we can usually handle it within a few days so you’re not stuck without heat all winter.
Most chimney leaks in Roxbury come from one of three places: damaged flashing, a cracked chimney crown, or deteriorating mortar joints. Flashing is the metal seal between your chimney and roof, and when it corrodes or pulls away, water runs straight into your attic. We fix that by removing the old flashing and installing new material with proper overlapping and sealant.
Chimney crowns crack over time, especially if they were poured too thin or without proper slope for drainage. Once the crown cracks, water sits on top of your chimney and soaks into the brick and flue. We repair crowns by resurfacing them with a waterproof mortar mix or, if the damage is severe, rebuilding the crown entirely.
Mortar joints break down from weather exposure, and once they’re compromised, water seeps into the chimney structure. We repoint those joints, removing old mortar and packing in fresh material that’s mixed to handle freeze-thaw cycles. In most cases, fixing the leak also means addressing the water damage inside—whether that’s replacing rotted wood in your attic or repairing stained drywall.
Most repairs take one to three days depending on the scope of work. A simple crown patch or flashing repair can be done in a day if the weather cooperates. Repointing mortar joints or replacing a section of damaged brick usually takes two days—one to prep and remove old material, another to rebuild and let it cure.
Larger jobs like a full chimney rebuild or extensive masonry work can take a week or more, especially if we’re waiting for materials or dealing with weather delays. Roxbury winters don’t always cooperate, and we’re not going to do masonry work in freezing temperatures if it means the mortar won’t set properly.
We’ll give you a timeline when we provide your estimate, and we’ll keep you updated if anything changes. Most homeowners are surprised at how fast we move once we’re on site—we’re not the kind of crew that starts a job and disappears for days at a time.
Yes. If your chimney is actively leaking during a storm, if you’re seeing smoke or sparks coming from cracks, or if part of your chimney has collapsed or is visibly unstable, call us right away. We’ll get someone out as quickly as possible to assess the situation and make it safe.
Emergency repairs usually focus on stopping immediate damage—tarping a leaking chimney, sealing a dangerous crack, or stabilizing loose brickwork. Once the urgent issue is handled, we’ll schedule a follow-up to complete the full repair when conditions are better.
We’ve been called out for everything from chimney fires to storm damage, and we understand that some problems can’t wait until Monday morning. If it’s a true emergency, we’ll do what we can to help—even if that means temporary measures until we can get back and finish the job properly.
