Commercial Waterproofing in Suwanee, GA
Most leaks we trace on Suwanee commercial buildings come in at a joint, not through the stucco. We replace failed sealant, correct flashing at windows and roof-to-wall transitions, and apply coatings that keep the envelope dry through Gwinnett’s storm season.

- Expansion joint repair
- Flashing & parapet details
- Elastomeric & breathable coatings

Suwanee storms find the weakest joint
Summer in Gwinnett means short, violent afternoon storms. Rain arrives sideways on a gust front, runs down the face of the building and collects at every horizontal ledge, window sill and joint. On a facade that is twenty years old, those joints are where the original sealant has dried out, lost adhesion or pulled away from one side, and the water goes straight in.
That is especially true on the mixed-use and multi-story buildings around Suwanee Town Center and along Peachtree Industrial Boulevard, where long runs of windows, balconies and storefront framing create hundreds of feet of joints on a single elevation.
A waterproofing program starts by finding which joints are failing and why. We inspect and cut test sealant for adhesion, check window perimeters, expansion joints and through-wall penetrations, and look at flashing where walls meet roofs and canopies. Then we remove failed sealant completely, prepare and prime the joint, install backer rod at the right depth and tool new sealant to the correct profile. Where the stucco itself is absorbing water, an elastomeric or breathable coating over the repaired wall adds a second line of defense.

Commercial waterproofing work in Suwanee
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.
Sealant programs sized for Suwanee buildings
A sealant program is planned around how the building is used and how much joint is on the wall, not just how old it is.
In Suwanee that ranges from a single-story strip center with storefront glazing to four- and five-story mixed-use and apartment buildings with balconies, breezeways and floor-line joints. We map every joint type on the building, test what is there, and phase replacement by elevation so the walls taking the most weather get done first.
Window & storefront perimeters
The most common leak source on Suwanee retail and office buildings, and the first thing we test.
Expansion & floor-line joints
Long horizontal joints on multi-story buildings move the most and fail across their full length.
South & west elevations
Afternoon sun and storm exposure age sealant on these walls first, so they often lead the phasing plan.
