Commercial Waterproofing in Alpharetta, GA

Most leaks we trace on Alpharetta commercial buildings come in at a joint: a window perimeter, an expansion joint, a parapet cap or a roof-to-wall transition. We find the one that is failing, replace sealant and flashing correctly, and protect the facade with the right coating.

Keep water moving

Sealant wears out. Many buildings are past due.

The office buildings, retail centers and apartment communities built around Alpharetta in the 1990s and early 2000s were mostly sealed once, at construction. Sealant on a south or west elevation that has baked through two decades of Georgia summers turns hard, pulls away from one side of the joint and lets water straight into the wall. Expansion joints between building sections and at parking deck connections have the same problem, only larger.

We start by locating the failure, not guessing at it. Moisture readings at window perimeters and joints show where water is getting in, and targeted water tests confirm it. Then we cut out the old sealant, clean and prime the joint faces, set the correct backer rod and install sealant at a profile that lets it move with the building.

Where flashing is missing at window heads, sills or roof-to-wall transitions, we add it. Where the stucco field itself is absorbing water, an elastomeric or breathable coating may be part of the scope. Larger buildings often benefit from a survey first, so the program is priced and phased by elevation.

What we waterproof

Commercial waterproofing work in Alpharetta

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.

Phased over budget cycles

Expansion joints

Failed expansion and control joints are rebuilt and sized so the joint can move with the building instead of tearing.

Joints that flex, not split

Window & storefront perimeters

Perimeter sealant, sill flashing and head details are corrected so water running down the wall is turned out, not in.

Water tested, then sealed

Parapets & roof-to-wall

Parapet caps, coping joints and roof-to-wall flashing are corrected where water enters the top of the wall.

Weak point on every roof

Elastomeric & breathable coatings

Elastomeric coatings to bridge fine cracks, or breathable coatings where the wall needs to dry outward, chosen for the substrate.

Matched to the wall

Penetrations & attachments

Tenant signage, light fixtures, mechanical lines, railings and balcony attachments are flashed and sealed where they pass through.

Sealed at every fastener

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.

Our process

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.

Moisture control in Alpharetta

Georgia weather finds every open joint

Wind-driven summer storms, long humid stretches and hot sun on exposed elevations make sealant the first part of an Alpharetta facade to fail.

On the taller office buildings along GA 400, driving rain hits the upper floors hard and tests every window joint at once. On low-rise retail, water collects at parapets and sign bands. On apartment communities, breezeway and balcony connections let water into the wall where residents may not report it for months. A sealant program matched to the building type stops each of these at the source.

Sun-worn elevations

South and west faces where sealant hardens and splits first.

Expansion joints

Joints between building sections and at deck connections, rebuilt to move.

Protective coatings

Elastomeric or breathable coatings chosen for the wall system underneath.

Questions & answers

Waterproofing & sealant questions in Alpharetta

What Alpharetta property managers ask about sealants, flashing and coatings.

How often should sealant be replaced on an Alpharetta office building?
There is no fixed number of years. It depends on the product, the exposure and how the joints were built. Once sealant is hard, cracked or pulling away on one side, it is no longer keeping water out, and a survey will show whether that is happening building-wide or on a few elevations.
Can you work on the upper floors of mid-rise buildings along GA 400?
Yes. Access is planned per building, typically with lifts or suspended access, and we coordinate with property management on parking, drop zones and tenant notices.
Will an elastomeric coating stop our leaks?
Not by itself. Coatings protect the stucco field, but most leaks come in at joints, windows and flashing. We fix those details first and recommend a coating only where the wall system and conditions call for it.
Do we need city approval for sealant replacement in Alpharetta?
Sealant replacement alone is usually treated as maintenance, but requirements vary with scope and location. Check with the City of Alpharetta if you are unsure, especially if the project also includes a color change.
How do you confirm where a leak is coming from?
We take moisture readings around the reported area, then water test suspect joints and openings one at a time until the leak reproduces. That way the repair goes where the water actually enters.

Stop the leak at the joint

Tell us where tenants or residents are seeing water. We will trace it, then send a written sealant and flashing scope for your Alpharetta property.
