Vapor-permeable protection for Irving chimneys facing hail, wind-driven rain, and shifting clay soil — from Las Colinas high-rises to central Irving's mid-century brick.
Irving's chimneys take a beating from two directions at once: hail and wind-driven rain hammering exposed brick, and the slow, grinding movement of North Texas clay soil beneath the foundation. Whether it's a tall stucco chase on a Las Colinas high-rise, a stone chimney in Valley Ranch, or original brick on a mid-century home in central Irving, sound masonry that looks fine today can be quietly absorbing water with every storm. Chimney waterproofing is the preventive step that stops that absorption before it becomes cracked mortar, spalling brick, or interior staining.
This service is not a leak repair. It's a vapor-permeable sealant applied to structurally sound brick and stone, designed to shed water while still letting the masonry breathe. That distinction matters — a non-breathable sealant can trap moisture inside the brick and accelerate freeze-thaw type damage during our occasional winter cold snaps. We only recommend waterproofing on chimneys that are already in good repair, which is why it's often paired with tuckpointing to fix mortar joints first, or follows a full chimney inspection to confirm the structure is sound.
Irving's housing stock spans several eras, and each one interacts differently with water. Newer builds in Las Colinas and Valley Ranch often feature tall, exposed chimney chases finished in stucco or EIFS — systems that look solid but can absorb moisture at seams and corners if left untreated. Older mid-century homes in central and historic downtown Irving typically have traditional brick chimneys that have already weathered decades of storms, and the mortar joints in these older systems are frequently more porous than they appear. Add in Irving's regular hail events, sideways rain during spring storms, and the way expansive clay soil shifts foundations and chimneys slightly over time, and you get small stress cracks that become entry points for water. Waterproofing seals the brick surface against that intrusion while the chimney is still healthy.
Waterproofing works best as a protective measure, not a rescue plan. Good candidates include chimneys with recent chimney repair or tuckpointing work, chimneys under five to ten years old that haven't been sealed, and any chimney where inspection reveals sound brick but signs of surface moisture absorption. If your chimney already has active leaks, a damaged crown, or missing components, those issues need to be addressed first — waterproofing over damage just delays the real fix.
We serve Las Colinas, Valley Ranch, and every Irving neighborhood in between, seven days a week.

Pricing depends on a handful of real factors: the height and accessibility of the chimney (tall Las Colinas chases take more time and equipment than a single-story central Irving home), the surface material being sealed (brick versus stucco/EIFS chases behave differently), how much prep or tuckpointing is needed beforehand, and the overall square footage of masonry being treated.

Waterproofing is preventive — it's applied to brick that's already sound to stop future water absorption. If your Irving chimney is actively leaking, that's a repair issue that needs to be resolved first, since sealing over damaged mortar or cracked brick won't fix the underlying problem.
No, we use vapor-permeable sealants specifically so the brick can still breathe. This matters in Irving because trapped moisture combined with occasional freeze-thaw swings can actually worsen cracking, so a breathable product is essential.
Yes, though stucco and EIFS chases common on newer Las Colinas and Valley Ranch homes are treated a bit differently than traditional brick. These systems can develop hairline seam cracks that let water in, so we evaluate the surface before recommending a sealing approach.
It varies by exposure, material, and how much hail and storm activity the chimney has taken, so we assess each one individually rather than quoting a blanket timeline. A periodic inspection is the surest way to know if resealing is due.
If your mortar joints are deteriorated, yes — waterproofing should go on sound masonry, not over damaged mortar. Many Irving homeowners, especially with older central Irving brick chimneys, pair tuckpointing and waterproofing together in one visit.
