From Willow Bend to West Plano, we shield sound brick chimneys from the clay-soil shifts and spring hail that quietly wear masonry down year after year.
Plano's chimneys take a beating that isn't always obvious from the ground. Between the clay-soil movement that shifts foundations across West Plano and Los Rios, and the freeze-thaw swings that crack open tiny gaps in mortar joints, brick chimneys are absorbing moisture long before anyone spots a stain on the ceiling. Chimney waterproofing is how Lowes Chimney Sweep gets ahead of that damage — a preventive, vapor-permeable sealant applied to sound masonry so water can't soak in, while the brick still breathes normally.
This isn't a leak repair. If your chimney is already letting water into the firebox or attic, that's a different job — often chimney leak repair or crown repair first. Waterproofing is a protective step applied to brick that's structurally sound, usually as a follow-up to tuckpointing once joints have been repaired. The sealant we use is vapor-permeable, meaning trapped moisture inside the masonry can still escape as vapor, while liquid water from rain and humidity is repelled at the surface.
Plano's chimney stock is a mix worth understanding. Many two-story homes built through the 1980s, 90s, and early 2000s in neighborhoods like Willow Bend and around the Legacy area were built with prefab factory-built fireboxes and metal chase chimneys — where the real vulnerability is the chase cover and flashing, not brick. But historic downtown Plano and pockets of West Plano still have full masonry chimneys, and those brick stacks are the ones that benefit most from waterproofing. Add in North Texas's expansive clay soil, which shifts foundations and opens hairline mortar cracks, plus the spring hail and wind that regularly batter chase covers and crowns, and you get chimneys that absorb moisture faster than homeowners expect. Waterproofing sound brick before that cycle starts is far cheaper than repairing spalled masonry later.
If you're not sure which category your chimney falls into, a chimney inspection is the fastest way to find out before any sealant goes on.
Protect sound brick now — before freeze-thaw cycles and hail season do their damage.
(214) 225-8874We start by confirming the brick is sound and dry, since sealant applied over active leaks or damaged mortar just traps the problem. Any needed repointing or chase cover work happens first. Then we apply the vapor-permeable sealant evenly across the masonry, letting it cure fully before the next rain. It's a straightforward service, but timing and prep matter — which is part of why we recommend pairing it with a routine chimney sweep so everything above the roofline gets looked at at once. For more on how this fits into a full maintenance schedule, see our post on the signs a chimney needs waterproofing and how freeze-thaw cycles damage Dallas-area chimneys.
Pricing depends on a handful of real factors: the height and accessibility of the chimney, how much surface area needs sealant, whether prep work like tuckpointing is needed first, and the current condition of the brick. A single-story masonry chimney in an older downtown Plano home is a different job than a tall two-story stack in West Plano. Our services start at $99, and we give every homeowner clear, upfront pricing before work begins — no surprises.

No. Waterproofing is a preventive step applied to sound, dry brick to stop future absorption. If your Plano chimney already has an active leak, that needs to be diagnosed and repaired first, often through crown repair or tuckpointing.
Not usually the metal chase itself, but many Plano two-story homes built from the 1980s through early 2000s have a mix of chase chimneys and masonry accents, and any exposed brick sections can still benefit from sealing.
Most sound masonry chimneys in the Plano area hold up for several years before resealing is needed, but homes exposed to more direct weather in West Plano or Willow Bend may need it sooner given regular freeze-thaw cycles.
No, we use a vapor-permeable sealant that blocks liquid water from soaking in while still letting existing moisture escape as vapor, which matters given how much Plano's clay soil and seasonal swings already stress the brick.
Before spring hail and wind season is ideal, since that's when chase covers and crowns take the most damage. Getting brick sealed ahead of those storms gives it a better chance to shed water instead of absorbing it.
