Protect your home from rain, animals, sparks, debris, and costly chimney damage with professional chimney cap installation & repair from ALC Chimney Service. A damaged or missing cap can allow water into the flue, weaken masonry, block airflow, and invite birds, squirrels, or raccoons into the chimney syste. Whether you have a rusted cap, a cracked crown, or squirrels in the flue, we will get your chimney sealed and protected.
A chimney cap is one of the most important protective parts of your fireplace system. It sits at the top of the chimney and helps block rain, leaves, pests, downdrafts, and flying sparks while still allowing smoke and gases to vent properly. If the cap is rusted, loose, missing, poorly fitted, or damaged by storms, your chimney can quickly develop leaks, odor issues, nesting problems, and masonry deterioration.
Our chimney cap installation & repair service includes a full top-side evaluation, measurement, material recommendation, fitting, sealing, and final safety check. Whether you need a new stainless steel chimney cap, a custom cover, or minor chimney cap repair, our goal is simple: protect your chimney before small issues become expensive repairs.
The cap is the cheapest part of your chimney and the one doing the most to protect everything beneath it. A sound cap keeps rain out of the flue and the masonry, which is what prevents the slow freeze-thaw cracking that destroys brick and mortar over time. It also stops sparks from reaching the roof and keeps birds, squirrels, and raccoons out of the firebox. Skip it, and you are looking at water damage, blocked flues, smoke backing into the room, and eventually a chimney rebuild that costs far more than the cap ever would. Airflow matters here too, since a properly fitted cap protects the draft instead of choking it.

Homeowners usually call us when they notice water stains near the fireplace, rust on the damper, animal noises, smoke drafting problems, or pieces of masonry around the chimney. These issues often start at the top of the system. A cracked crown, broken screen, loose fasteners, missing cap, or damaged rain cover can expose the flue to moisture and pests.
Rust is the most common issue we see, since cheap galvanized caps corrode within a few years and streak the brick.
Storms regularly blow caps loose or off entirely, leaving the flue open to rain and nesting birds.
Older homes often have cracked or spalling crowns that let water seep into the chimney structure.
When critters keep getting in, our animal proof chimney cap installers fit a tight mesh screen that stops them without hurting the draft.
If the existing cover is too far gone, we replace it with a stainless steel cap for chimney tops that outlasts the rest of the roof.
Water leaks often start around damaged flashing where the chimney meets the roof, allowing moisture to enter the walls.
Smoke entering the roomA blockage or draft issue is likely present — an inspection will locate the source and a thorough cleaning will restore proper airflow.
Black buildup inside chimneyThat dark coating is creosote — a flammable byproduct of burning wood that must be professionally removed to prevent chimney fires.
Water leaking near fireplaceWater intrusion usually points to damaged flashing, a cracked crown, or deteriorating masonry — each of which lets rain travel directly into your home.
Chimney leaning or badly damagedA leaning or severely compromised chimney is a structural safety hazard. A full rebuild is the appropriate solution when repairs are no longer sufficient.
For new construction or a first cap, our chimney cap installation service fits the right cover to your flue and seals it to handle wind and rain. Most installs wrap up in one visit.
If your cap is loose, dented, or just missing its screen, our chimney cap repair services refasten, rescreen, and reseal the existing cover when it is still worth saving.
A cap that has rusted through or cracked is past repair, so we handle both chimney cap repair and replacement and fit a quality stainless unit sized to your chimney.
Cracks in the crown let water straight into the masonry. Many of our visits combine chimney crown repair and cap installation so the entire top is protected at once.
Once a crown is crumbling beyond patching, our chimney crown replacement rebuilds the top with fresh, weather-rated masonry that sheds water properly.
On a new or rebuilt chimney, our chimney crown installation pours a sloped crown with an overhang that pushes water away from the brick for added protection.
Need a chimney rain cap? We install durable caps that keep rain out of your firebox while protecting proper airflow and draft performance.
To keep birds and squirrels out of the flue, our animal-proof screens and chimney top protection services seal the opening without choking airflow.
A stainless steel cap resists rust and lasts for decades, making it a smart upgrade that offers reliable protection in all weather conditions.

We have spent years working on chimneys, so we know what weather does to a cap and which ones actually survive it. When people look for the best chimney cap installers near me, what they usually want is someone honest, and that is the part we take seriously. You get straight answers, photos of the real problem, and a price that does not change after the work is done. We install quality stainless rather than the thin galvanized caps that fail in a few seasons, and we stand behind the workmanship. If a repair will hold, we will tell you, instead of selling you a replacement you do not need. And when a cap blows off in a storm, we answer the phone and get out fast.
Our technicians understand how North Texas weather, wind, storms, heat, and seasonal animal activity affect chimney systems. We use strong materials, proper sizing, careful installation methods, and clear communication from inspection to final check.

ALC Chimney Service proudly serves Dallas, TX and surrounding areas. When you need help with a chimney cap, you usually want someone local who responds quickly, explains the issue clearly, and shows up when they say they will. Whether it is a new chimney cap installation or a repair for an existing one, our team makes the process simple. We schedule at a convenient time, keep you updated, and make sure your chimney is properly protected without wasting your day.










For a standard single-flue cap, chimney cap installation cost usually runs about $150 to $400 installed, depending on size and material. A basic chimney cap repair cost is lower, often $75 to $250 if the existing cap just needs refastening or a new screen. A full chimney cap replacement cost lands closer to $250 to $700 for a quality stainless unit, and large multi-flue or custom covers can run higher. We give you a firm number after we see the chimney, so you are never guessing.
A single-flue cap usually slips over the flue tile and tightens with screws or clamps, while a multi-flue cap is anchored to the crown with masonry fasteners and sealant. It sounds simple, but roof access, the right fastener for your tile size, and a proper seal are where DIY attempts tend to fail. We bring the correct cap and weatherproof everything so it does not lift in high wind.
Replacing a cap means removing the old unit, cleaning the flue tile or crown surface, and fitting a new cap sized to your opening. If the old fasteners are rusted into the masonry, they often have to be cut out, which is the part most homeowners would rather hand off. We size and install the replacement in a single visit for most homes.
A cracked metal cap is usually replaced rather than patched, since welds and coatings rarely hold once they split. A cracked concrete or masonry cap can sometimes be sealed with a flexible crown coating when the damage is minor, but deep cracks call for a rebuild. We will show you the crack and explain which route actually lasts.
Surface rust on a stainless cap can be cleaned, but a galvanized cap that has rusted through is past saving and should be swapped for stainless. Rust usually means water has already been getting into the flue, so we check the liner and crown while we are up there.
Repairing a concrete chimney cap, often called the crown, starts with clearing loose material and filling cracks with a flexible crown sealant rated for masonry. Badly deteriorated crowns are rebuilt with fresh mortar or a poured cap. A patch buys time on small cracks, while a rebuild is the right call once chunks are missing.
Minor chimney crown repair, like sealing hairline cracks, often runs $200 to $500, while a full crown rebuild can range from $1,000 to $3,000 depending on size and access. Homeowners searching chimney crown repair near me are sometimes quoted a flat patch price when they really need a rebuild, so we inspect first and recommend only what the chimney needs.
If the cap is loose, missing a screen, or lightly rusted, a repair is usually enough. Once the metal has rusted through, cracked, or blown off, replacement is the safer spend. People who search chimney cap replacement near me after a storm almost always need a new unit rather than a patch, and we can confirm that in a few minutes on the roof.
Yes. Short-notice repairs are available for storm damage and animal intrusions, with same-week appointments and emergency service when a missing cap is letting rain into the home.
