From Las Colinas high-rises to mid-century homes in central Irving, a properly sized cap is often the one thing standing between your chimney and Texas weather.
Drive through Irving on a windy afternoon and you'll notice something a lot of homeowners never think about until it's too late: the top of the chimney. Between the newer stucco and EIFS chases rising over Las Colinas and Valley Ranch and the older brick stacks scattered through historic downtown Irving, an uncapped flue is more common than most people realize — especially on homes built before caps were standard, or additions and remodels where the chase was never finished out properly. If your chimney has never had a cap, or you've simply never noticed one up there, this is the service that closes that gap before hail, wind-driven rain, or a curious squirrel finds it first.
A lot of the calls we get in Irving aren't about fixing a broken cap — they're about a chimney that was never capped to begin with. This happens often on older central Irving homes where the original construction skipped it, and on newer Las Colinas builds where a tall, exposed chase was framed and stuccoed but the finishing metalwork at the top got overlooked. Either way, an open flue means rain falling straight down the liner, embers escaping without a spark guard, and an open invitation for birds, raccoons, and squirrels looking for shelter.
Before we install anything, we look at the flue itself — its shape, its size, and how it ties into the rest of the system. A quick chimney inspection at this stage confirms there's no existing damage to the crown or liner that should be addressed first, since a cap installed over an already-cracked crown won't solve the underlying problem.
Not every chimney needs the same cap. A single-flue home just needs one properly fitted cap sized to that specific opening — too small and it won't seal out wind-driven rain, too large and it can rattle loose in Irving's spring storms. Multi-flue chimneys, which show up often in Irving's older neighborhoods where a furnace flue and fireplace flue share one chase, usually call for a single larger multi-flue cap or a custom-built cover, depending on flue spacing and chase design.
Getting this right the first time matters more than people expect. A cap that's the wrong size either restricts draft or leaves gaps animals can squeeze through — we've seen both on homes across Irving where a previous owner installed something off-the-shelf without measuring.
Irving's chimney landscape is genuinely varied, and that shapes how we approach a first-time cap install. In Las Colinas, tall, exposed stucco and EIFS chases catch wind and hail differently than a low-slung brick chimney — the height alone means more exposure to driving rain, and hail impact on the surrounding chase can eventually work its way toward an uncapped opening. Valley Ranch's newer construction often has similar chase styles, and the flat, open roof lines common in these subdivisions give wind more of a runway straight at the flue.
Central and historic downtown Irving tell a different story. Mid-century homes here frequently have masonry chimneys built decades before capping was routine, and clay-soil movement across the DFW area over the years can shift a chimney's crown just enough to open small gaps that an uncapped flue only makes worse. In all these cases, the fix is the same category of problem — no cap, or the wrong cap — but the sizing and mounting approach differs based on chase material, flue count, and roof pitch.
A properly installed cap does three jobs at once, and all three matter in Irving's climate: it blocks rain from tracking down the flue during wind-driven storms, it stops birds and animals from nesting in an open chimney, and it holds sparks and embers back with a mesh screen so they don't land on a roof. If any of these have already caused damage — a stained crown, a chewed-up damper, or a liner that's seen too much moisture — that's a separate repair, often covered under chimney crown repair or animal removal, rather than a first-time cap install.
Whether it's a Las Colinas high-rise chase or a central Irving brick stack, we'll size and install the right cap the first time.
(214) 225-8874Cap installation pricing depends on a handful of real factors rather than a flat number: whether the chimney is single-flue or multi-flue, the flue's shape and size, roof pitch and chase height (a factor that shows up often on Las Colinas' taller stucco chases), the cap material — stainless steel, copper, or galvanized — and whether any crown repair is needed alongside it. Homes in Valley Ranch's newer subdivisions with straightforward single-flue setups typically install faster than an older central Irving chimney needing a custom multi-flue cover.

For homeowners weighing this against ongoing upkeep, our guide to what a chimney cap actually protects and our notes on spotting hail damage on a chimney are worth a look, and pairing the install with a chimney sweep or chimney waterproofing service is common for homes that haven't had recent maintenance.
"Very pleased with the professionalism and promptness of service. The chimney sweep was done quickly and efficiently at significantly less cost than the first quote I got from another company. Happy to recommend Lowes Chimney Sweep to anyone in Plano!"

The easiest way is to look from the ground with binoculars or check from a second-story window facing the chimney — if you don't see a raised metal or mesh cover at the top of the flue, it's likely uncapped. This is especially common on older central Irving homes and on some newer Las Colinas chases where the cap was overlooked during construction.

Yes. Homes with a shared chase for both a fireplace and furnace flue, which we see often in older Irving neighborhoods, usually need either one larger multi-flue cap or a custom-built cover sized to both openings rather than two separate single caps.
A properly sized cap keeps rain from tracking straight down the flue during Irving's storms, which is one of the most common causes of interior water staining on uncapped chimneys. It won't stop hail from hitting the chase itself, but it does protect the opening that hail damage can eventually work its way toward.
Yes, though taller exposed chases typically need extra attention to mounting and flashing since they catch more wind. We factor chase height and roof pitch into the sizing and installation approach for these homes.
Most single-flue installations are completed in one visit. Multi-flue or custom covers on older central Irving chimneys can take a bit longer depending on flue configuration, and we'll walk you through the timeline as part of your Free Online Quote.
