DensGlass Sheathing Replacement in Peachtree City

When moisture readings show wet sheathing behind the stucco or EIFS of a Peachtree City office, retail or multifamily building, surface repairs will not hold. We open the wall, replace damaged sheathing with glass-mat gypsum board, tie it into the weather barrier and rebuild the finish.

Behind the facade

Rotten sheathing won’t hold a patch

Behind most commercial stucco and EIFS is a layer of sheathing that the cladding is fastened or bonded to. On many older buildings that layer is paper-faced gypsum or wood-based panels, and once water gets past a failed joint or flashing, it soaks in, softens and loses its strength. The finish may still look intact while the board behind it is crumbling.

That is why we take moisture readings before scoping a repair. On Peachtree City buildings, wet sheathing shows up most often below window corners, under parapet and roof-to-wall transitions, beside balcony and breezeway connections, and along the base of the wall.

Where readings are high, we remove the cladding in the affected area and cut back to dry, sound sheathing. We check the framing, replace damaged board with glass-mat gypsum sheathing such as DensGlass, which resists moisture far better than paper-faced board, and lap the new weather barrier into the existing one so water drains out instead of behind it. Then we correct the original leak source and rebuild the stucco or EIFS to match.

What we rebuild

Sheathing & substrate repairs in Peachtree City

The facade only tells you there is a problem. These are the layers we rebuild once a wall is open.

Water-damaged sheathing

Swollen OSB, delaminated plywood and softened gypsum board cut back to sound material and replaced with glass-mat board.

Moisture readings guide the cut

Weather-resistive barrier

New barrier lapped over the sheathing and tied into the existing barrier at every edge of the repair.

Every lap sheds water down

Window & storefront openings

Sill pans and jamb flashing integrated with the barrier so water that reaches an opening drains out.

Where most damage starts

Parapets & roof-to-wall joints

Flashing corrected where a roof, balcony or breezeway meets the wall, a common source of wet sheathing.

Coordinated with the roofer

Termite-damaged substrate

Sheathing and trim damaged by termites replaced, and cladding that runs below grade corrected.

Treatment stays with pest control

Framing documented

Corroded steel studs or decayed wood framing are photographed and referred to the owner’s engineer before the wall is closed.

Engineer decides structure

Choosing the board

Why glass-mat board goes back in

Putting new OSB or paper-faced gypsum back behind the cladding puts the same vulnerable material in the same spot on a wall that has already shown it can get wet. Glass-mat gypsum sheathing has fiberglass facings in place of paper and a moisture-resistant core, so a wet spell does not break it down or feed mold the way wood and paper can.

It is not waterproof on its own. The weather barrier, flashing and sealant joints are still what keep water out, and every replacement we do includes them. Where the sheathing is part of a building’s structural design, or where we find damaged studs, tracks or framing, the owner’s engineer specifies that repair and we rebuild the wall to it. You see photos of the open wall before anything is closed.

Our process

How a sheathing replacement runs on site

The wall is open for as short a time as possible and protected at the end of every day, with the work phased around tenants and residents.

Survey & map

We take moisture readings across the elevation to find the edges of the wet area and the leak source before any cladding comes off.

Readings mapped on photos
Leak source identified
Itemized written scope

Open & replace

Cladding is removed over the damaged area, wet sheathing is cut back to sound material, and glass-mat board is installed.

Daily weather protection
Framing issues documented
Changes approved first

Barrier, flash & finish

New barrier and flashing are lapped into the existing wall, then the stucco or EIFS is rebuilt and color matched.

Barrier lapped correctly
Flashing at every opening
Color & texture matched

Soft or bulging areas on your facade?

The longer sheathing stays wet, the more of the wall it takes with it. A moisture survey shows how far it has gone.

Substrate repair in Peachtree City

Opening walls on occupied Peachtree City buildings

Sheathing replacement means opening an exterior wall, often right outside an occupied office suite, storefront or apartment.

On Peachtree City office buildings along the highway corridors, village center retail and multifamily communities, we plan wall openings so they are closed back up and weather-tight at the end of each work day, or protected if they cannot be. Interior finishes stay in place where possible, and we coordinate with your property manager so tenants and residents know what to expect.

Georgia’s afternoon thunderstorms are the main scheduling factor. We keep openings small, watch the forecast and keep tarps and temporary protection on site.

Mapped before cutting

Moisture readings define the repair area so we open only what is needed.

Closed each day

Openings made weather-tight or protected before crews leave the site.

Lapped to drain

New weather barrier lapped into the old so water runs out, not in.

Questions & answers

Sheathing replacement FAQ for Peachtree City

What Peachtree City owners and managers ask when a survey finds wet substrate.

Do we need a permit to replace sheathing on a Peachtree City building?

Opening walls and replacing sheathing or framing may require a permit depending on the extent. Check with the Peachtree City building department before work starts; we can provide the scope for the application.

Will tenants or residents have to move out during the repair?

Not usually. The work is done from the outside. We protect interior spaces, keep openings small and close them up quickly, and coordinate access with your property manager.

How do you know how far the damage goes?

Moisture readings map the wet area before we cut. Once the wall is open, we cut back until the sheathing is dry and sound, and we document what we find with photos.

What if the framing behind the sheathing is damaged too?

We check the framing whenever the wall is open. Damaged studs or plates are repaired or replaced, and we tell you before proceeding if that changes the scope.

Why use glass-mat gypsum instead of the original sheathing?

Glass-mat gypsum board resists moisture and mold much better than paper-faced gypsum and is widely used behind stucco and EIFS. It gives the repaired wall a more durable substrate.
