Waterproofing is what keeps water in the places it belongs. Banner Roofing & Construction installs and repairs waterproofing systems on commercial buildings, multifamily communities, and homes across North Texas — traffic-bearing deck and balcony coatings, above- and below-grade wall waterproofing, sealant and expansion joint replacement, and parking structure and podium deck systems.
Waterproofing rarely fails all at once. It fails at a joint, a termination, a penetration, or a transition — and it usually shows up somewhere else entirely. Our team traces the leak to its actual source before writing a scope, because coating over the wrong surface is the most expensive way to not fix a leak.
What waterproofing work do we do?
- Traffic-bearing deck and balcony coatings — pedestrian-rated urethane and acrylic systems for walkways, breezeways, balconies, and stair landings that have to shed water and take foot traffic.
- Above-grade wall waterproofing — elastomeric wall coatings, breathable water-repellent sealers on masonry and stucco, and through-wall flashing correction.
- Below-grade waterproofing — foundation walls, retaining walls, and planter boxes where standing soil moisture is working against the structure.
- Sealant and joint replacement — perimeter caulking at windows and doors, control and expansion joints, panel joints, and penetration seals. This is the single most common failure we’re called out for.
- Parking structures and podium decks — vehicular-rated deck systems, joint sealing, and drain-area detailing.
- Roof-to-wall and transition detailing — the seams between our commercial roofing scope and the wall assembly, where a lot of “mystery leaks” actually live.
Repair, maintain, or replace the system?
Waterproofing gets sold as replacement far more often than it needs to be. Our order of operations is the same one we use on roofs:
- Repair first. Isolated coating failures, blisters, delaminated patches, failed terminations, and split sealant joints can very often be cut out and re-detailed without touching the rest of the deck.
- Maintain second. Most deck coating systems are designed to receive a recoat well before the base layer is compromised. Recoating on schedule costs a fraction of a tear-off and resets the clock.
- Replace when it’s earned. When the substrate is saturated, the membrane has lost adhesion across the field, or the deck itself has structural damage, we say so plainly — and we show you the photos that led us there.
Signs your waterproofing is failing
- Ceiling stains on the floor below a balcony, walkway, or breezeway
- Bubbling, blistering, cracking, or chalking on a deck surface
- Sealant that has pulled away from a window frame, panel joint, or handrail post
- Efflorescence — white mineral staining — on masonry walls
- Standing water that doesn’t drain within a day of rain
- Soft, spongy, or flexing spots underfoot on an elevated walkway — this one is urgent; see life safety repairs
Why North Texas is hard on waterproofing
DFW puts unusual stress on exterior systems. Wide temperature swings drive constant expansion and contraction at every joint, so sealants that would last a decade in a mild climate fatigue and split here far sooner. Expansive clay soils shift with the wet-dry cycle, which moves foundations and opens cracks in walls and flatwork. And hail and wind-driven rain find every unsealed termination on a building in a single afternoon. Systems in North Texas need to be inspected on a real schedule, not when someone reports a stain.
Why Banner for waterproofing
- We find the source, not the symptom. Our assessments trace water to its entry point and document it with photos before anyone quotes a coating.
- Manufacturer specification, followed. Surface prep, primer, mil thickness, and cure times are where waterproofing succeeds or fails. We don’t shortcut them to hit a schedule.
- Occupied-property experience. We phase balcony and walkway work so residents keep safe egress throughout.
- Veteran-owned, 5.0 stars across 117 Google reviews, licensed and insured, serving North Texas from Frisco.
GAF Master Elite certification and RCAT License 03-0562 apply to Banner’s roofing operations. Waterproofing work is performed licensed and insured to the requirements of the trade and jurisdiction.
Waterproofing in North Texas — common questions
How long does a deck or balcony coating last?
Most pedestrian traffic coatings are designed for roughly 7 to 10 years before they need recoating, though heavy traffic, direct sun, and standing water shorten that. The important part is that these systems are meant to be recoated on schedule — recoating before the base layer is compromised costs a fraction of a full tear-off and replacement.
Can waterproofing be repaired, or does it all have to be replaced?
Very often it can be repaired. Isolated blisters, delaminated patches, failed terminations, and split sealant joints can usually be cut out and re-detailed without touching the rest of the deck. We only recommend full replacement when the substrate is saturated, adhesion has failed across the field, or the deck has structural damage — and we show you the photos that led us there.
Why does my balcony leak when the coating looks fine?
Because most waterproofing failures happen at the edges, not the field. Terminations at the wall, door thresholds, railing post penetrations, drains, and scuppers are where water actually gets in. A coating can look perfect across the middle and still be letting water into the structure at a detail you cannot see from standing on it.
What is efflorescence and should I worry about it?
Efflorescence is the white, chalky mineral staining you see on masonry walls. It means water is moving through the wall and carrying salts to the surface as it evaporates. It is cosmetic on its own but it is a reliable signal that the wall assembly is taking on water somewhere, and it is worth investigating before it becomes interior damage.
Do you waterproof occupied apartment buildings?
Yes. We phase balcony and walkway work building by building so residents always have safe egress, post advance notice for anything affecting access, and keep the site clean daily. Your on-site staff gets a supervisor’s direct number.
How much does waterproofing cost?
It depends entirely on the system, the square footage, and how much repair the substrate needs first — which is why we assess and document before quoting. A sealant joint replacement is a small line item; a full traffic deck replacement across a community is a capital project. You will get a written scope with the pricing broken out either way.
