Commercial Waterproofing in Kennesaw, GA
Most commercial leaks in Kennesaw enter through a joint, not through the stucco itself. We replace failed sealant and expansion joints, correct flashing and apply the right coating, so storm water stays out of the wall and out of tenant spaces.

Kennesaw commercial stucco & EIFS. Property managers, boards, owners & builders.
Sealant joints are the first to go
Every commercial facade in Kennesaw depends on a few hundred feet of sealant. It closes the joints between EIFS panels, the perimeters of storefronts and windows, expansion joints between building sections, and the transitions where stucco meets metal coping, brick or fiber cement. On a south- or west-facing elevation, years of sun and heat harden that sealant until it pulls away from one side of the joint, and the next storm runs straight in.
We look at the whole water-management system, not just the beads you can see. That means checking that joints were built with backer rod at the right depth, that windows and storefronts have sill and head flashing, that roof-to-wall transitions have kickout and counterflashing, and that the base of the wall can drain.
From there the scope can be a targeted repair, a full joint replacement program phased by elevation, or an elastomeric or breathable coating to tighten up a wall with widespread hairline cracking.
Commercial waterproofing work in Kennesaw
These are the details we check and correct on office, retail, multifamily and hospitality buildings.
Sealant replacement programs
Old sealant is cut out, joints cleaned and primed, and new backer rod and sealant installed, building-wide or elevation by elevation.
Expansion joints
Failed expansion and control joints are rebuilt and sized so the joint can move with the building instead of tearing.
Window & storefront perimeters
Perimeter sealant, sill flashing and head details are corrected so water running down the wall is turned out, not in.
Parapets & roof-to-wall
Parapet caps, coping joints and roof-to-wall flashing are corrected where water enters the top of the wall.
Elastomeric & breathable coatings
Elastomeric coatings to bridge fine cracks, or breathable coatings where the wall needs to dry outward, chosen for the substrate.
Penetrations & attachments
Tenant signage, light fixtures, mechanical lines, railings and balcony attachments are flashed and sealed where they pass through.
Choosing the right waterproofing scope
A coating can’t fix a missing flashing, and new sealant won’t help a parapet whose cap is open. We start with the details where water is actually getting in, and only recommend a coating when the face of the wall needs one.
Coating choice matters too. Elastomeric coatings bridge hairline cracks and shed rain well, but a non-breathable film over a wall that is already wet can trap moisture. Where readings show wet areas, we repair those first.
For sealant, the question is usually full program or targeted repair. If the joints are the same age everywhere, replacing them in one program is usually the better value. If failures are concentrated on one or two elevations, we can phase the work so it fits operating budgets or reserves.
| Scope | Best for | Result |
|---|---|---|
| Targeted sealant repair | Failures on one elevation | Leaks closed |
| Full sealant program | Joints the same age everywhere | Building resealed |
| Flashing correction | Parapet & opening leaks | Water turned out |
| Elastomeric coating | Sound wall, many hairline cracks | Cracks bridged |
| Breathable coating | Dry stucco needing protection | Sheds rain, dries out |
How we waterproof an occupied building
Sealant and coating work depends on weather and cure time, so we plan the sequence and access with you before work starts.
Survey & test
We walk every elevation, check sealant adhesion and condition, take moisture readings at windows and joints, and water test where tenants have reported leaks.
- Sealant condition by elevation
- Moisture readings mapped
- Leak points confirmed
Scope & phasing
You get an itemized scope that separates active leak repairs from preventive work, with phasing options by elevation or by building.
- Itemized by elevation
- Program or targeted options
- Access & scheduling plan
Seal, flash & coat
Failed joints come out and are rebuilt, flashing is corrected, any wet substrate found along the way is replaced, and coatings go on where the wall needs them.
- Joints primed & tooled
- Flashing corrected
- Daily cleanup
Tenants reporting leaks after storms?
That usually points to a joint or flashing detail. A water test can confirm the source before you commit to a full program.
Often paired with waterproofing
Sealant and flashing work often turns up damage that has to be repaired first, or a wall that should be tested before anything is sealed.
Envelope Inspections
Moisture surveys, water testing and written condition reports for owners, boards, lenders and buyers.

Kennesaw’s summers bring heat, humidity and fast-moving thunderstorms, and that combination is hard on exterior joints.
Wind-driven rain hits tall, exposed elevations harder than sheltered ones, which is why we often find failures concentrated on one side of a building. Large retail and office buildings along the I-75 corridor, apartment buildings on open sites near Chastain Road and three- and four-story buildings with flat parapets all show the pattern. We map failures by elevation so the scope targets the walls that are actually leaking.
Heat & UV
Sun-facing elevations age sealant fastest; joints harden, crack and lose adhesion.
Wind-driven rain
Storm rain is pushed sideways into joints, window perimeters and parapet caps.
Movement
Daily heating and cooling stretches expansion joints that were built too narrow or too shallow.
