A proper chimney replacement stops water from destroying your ceilings and walls. It eliminates the carbon monoxide risk that comes with cracked flue liners. And it means your heating system works safely all winter without you wondering if something’s about to go wrong.
You’re not just fixing visible damage. You’re addressing what’s happening inside the chimney stack—the freeze-thaw cycles that crack masonry from the inside out, the salt air that corrodes metal components, and the moisture that’s been seeping into your home’s structure for months or years.
When the work’s done right, you get a chimney that handles Long Island winters without falling apart. No more emergency calls during nor’easters. No more water stains spreading across your living room ceiling. Just a system that works the way it’s supposed to.
Home Team Construction has spent over a decade working on homes in Mastic and throughout Suffolk County. We’re licensed, insured, and we don’t use subcontractors—every person on your property is trained by us and held to our standards.
We’ve seen what coastal weather does to chimneys here. The freeze-thaw cycles that crack brick in January. The salt air that rusts chimney caps and accelerates spalling. The spring storms that turn small leaks into major interior damage.
Our reputation is built on doing the work right the first time, because we’re not disappearing after the job. We’re local contractors who live in this community, and our work reflects that.
We start with an inspection to determine if you need a full chimney replacement or if specific components—like the chimney cap, flashing, or liner—can be addressed individually. If the masonry is crumbling, the stack is leaning, or water damage has compromised the structure, replacement is the only option that makes sense.
Once we’ve given you an upfront estimate, we schedule the work during dry weather with moderate temperatures. That’s critical for proper mortar curing and waterproofing. We carefully dismantle the existing chimney down to a stable point, usually the roofline or below, depending on the extent of damage.
The rebuild uses materials specifically chosen for Suffolk County’s coastal conditions—impact-resistant components, properly sized flue liners, and weather-resistant masonry. We install new flashing that actually seals against your roof, a chimney cap that won’t rust out in two years, and a crown that sheds water instead of absorbing it.
The final step is a thorough cleanup and a walkthrough so you understand exactly what was done and how to maintain it. You’re not guessing about whether the work was completed properly—you can see it.

Every chimney replacement includes a complete rebuild of the chimney stack using masonry designed to withstand coastal moisture and temperature swings. We install a stainless steel flue liner that resists the corrosive byproducts of combustion and provides a proper draft for your heating system.
The chimney cap we install is built to keep out rain, snow, and animals while allowing proper ventilation. Flashing is custom-fit and sealed to prevent the water infiltration that destroys so many Long Island chimneys. The chimney crown is sloped and sealed to direct water away from the masonry instead of letting it soak in.
In Mastic, where salt air accelerates deterioration and freeze-thaw cycles happen dozens of times each winter, these details matter. Homes here face harsher conditions than most of the country, and your chimney needs to be built accordingly. We’re not installing a generic chimney—we’re building one that accounts for the specific weather patterns, humidity levels, and coastal exposure that define Suffolk County.
Most complete chimney replacements in Mastic run between $10,000 and $15,000, depending on the height of your chimney, accessibility, materials, and how much of the structure needs rebuilding. If we’re only replacing the chimney stack above the roofline, costs are lower. If the chimney needs to be rebuilt from the foundation up, or if there’s extensive interior damage to repair, costs increase.
Suffolk County pricing tends to run higher than national averages because of stricter building codes, higher labor costs, and the need for coastal-grade materials that can handle salt air and freeze-thaw cycles. But that upfront investment prevents the exponentially higher costs that come from repeated patch repairs or structural damage to your home’s interior.
We give you a detailed, upfront estimate before any work starts. You’ll know exactly what you’re paying for and why, with no surprises when the job’s done.
If your chimney is leaning, has large cracks running through multiple bricks, or shows signs of spalling—where the brick surface is flaking off in chunks—you’re likely looking at replacement. Water stains on your ceiling near the fireplace, pieces of brick in your yard after storms, or a chimney that looks visibly tilted are all signs the structure is failing.
Minor issues like a damaged chimney cap, small mortar cracks, or flashing that’s pulled away from the roof can often be repaired. But if the masonry has been absorbing moisture for years, or if freeze-thaw damage has compromised the structural integrity, repairs just delay the inevitable. We’ve seen too many homeowners spend thousands on repairs only to need a full replacement two years later.
During the inspection, we’ll tell you honestly whether repair makes sense or if you’re throwing money at a chimney that’s beyond saving. Our goal is to give you the most cost-effective solution, not to upsell you on work you don’t need.
Long Island’s coastal climate is brutal on chimneys. Salt air draws moisture into brick like a sponge, and when temperatures drop, that moisture freezes and expands. Each freeze-thaw cycle—and you get dozens per winter here—widens existing cracks and creates new ones. The salt accelerates everything, causing brick to literally crumble in chunks.
Coastal storms dump rain horizontally into chimney structures, and the constant humidity means masonry never fully dries out. Chimney caps rust faster here. Flashing deteriorates quicker. Mortar joints break down at an accelerated rate compared to chimneys inland or in drier climates.
That’s why chimneys in Mastic and throughout Suffolk County require more frequent maintenance and often need replacement sooner than the national average. It’s not poor construction—it’s the reality of building materials constantly exposed to salt, moisture, and temperature extremes.
Water finds a way in, and once it does, the damage spreads fast. You’ll see stains on your ceiling and walls near the fireplace. Your insulation gets soaked and loses its effectiveness. Drywall starts to deteriorate. Wooden structural elements can rot. And all of this is happening behind walls where you can’t see it until the problem is severe.
A compromised flue liner means combustion gases—including carbon monoxide—can leak into your home instead of venting safely outside. Creosote buildup accelerates in damaged chimneys, increasing your risk of a chimney fire. And if the chimney structure is unstable, you’re looking at a potential collapse that could damage your roof or worse.
The cost to fix these problems grows exponentially the longer you wait. A $2,000 repair ignored today becomes a $15,000 emergency next year, plus the cost of repairing interior water damage. We’ve seen it happen repeatedly, and it’s always more expensive than addressing the issue early.
Most chimney replacements take three to five days, depending on the size of your chimney, weather conditions, and the extent of the rebuild. We need consecutive days of dry weather for proper mortar curing and waterproofing, which is why spring and fall are ideal times for this work in Mastic.
We’re not rushing through the job to move on to the next one. Proper chimney construction requires time for materials to cure and for each phase to be completed correctly. Flashing needs to be installed and sealed properly. The flue liner has to be sized and fitted correctly. The chimney crown needs time to cure before it can effectively shed water.
You’ll have full access to your home during the work, though there will be noise and activity on your roof. We protect your property, clean up daily, and make sure the site is secure each night. When we’re done, you’re not left with a mess to deal with.
Yes. We offer flexible payment plans including 18-month interest-free financing options, because we understand that chimney replacement is a significant investment. A $12,000 chimney rebuild is a lot to pay upfront, especially if the problem caught you by surprise during winter.
Financing lets you get the work done now—before water damage spreads or a failing chimney creates a safety hazard—without draining your savings or putting off other necessary expenses. You’re not choosing between a safe chimney and your financial stability.
The application process is straightforward, and we’ll walk you through the options that fit your budget. Our goal is to make quality chimney replacement accessible, not to price you out of the work your home actually needs.
