DensGlass Sheathing Replacement in Sandy Springs

When water has been getting behind stucco or EIFS on a Sandy Springs apartment, condominium or office building, the sheathing is usually what has paid the price. We open the wall, replace damaged board with glass-mat gypsum sheathing and tie it into a new weather barrier.

Behind the facade

Wet board has to come out from the outside in

Many multifamily and low-rise commercial buildings in Sandy Springs were framed in wood with paper-faced gypsum or OSB sheathing behind the cladding. Those boards tolerate very little water. After years of slow leaks at windows, balconies and roof-to-wall joints, the board softens, the fasteners lose their grip and the framing behind can start to decay.

No coating or sealant can reverse that. The cladding has to be removed over the damaged area, and we keep opening until the moisture readings show dry, sound material. The damaged sheathing comes out, framing is inspected and repaired where needed, and glass-mat gypsum board goes in. It holds up to moisture much better than paper-faced board and gives the new weather barrier and cladding a stable base.

The weather barrier is lapped into the existing barrier around the opening, windows and penetrations are flashed, and the stucco or EIFS is rebuilt and finished to match. Every opening is photographed before it is closed, so managers and boards have a record of what was found behind the wall.

What we rebuild

Sheathing & substrate repairs in Sandy Springs

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.

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.

Sheathing repair in Sandy Springs

Where we find the wettest walls

Behind the cladding of Sandy Springs buildings, sheathing damage clusters at a handful of details.

On apartment and condominium communities, balconies and breezeways are the usual sources, along with windows stacked floor over floor. On office buildings, parapets and window sills are the common culprits. Shaded elevations under the tree canopy dry slowly and tend to show the most damage once opened.

Balcony connections

Water entering where balconies and breezeways tie into the wall on multifamily buildings.

Stacked windows

Leaks at upper windows running down and wetting the sheathing floors below.

Decay & termites

Framing softened by long-term moisture, sometimes with termite damage alongside.

Questions & answers

DensGlass sheathing replacement FAQ

What Sandy Springs managers and boards ask when a wall has to be opened.

How do you know how much sheathing needs replacing?

Moisture readings before work starts give an estimate of the affected area. Once the wall is open, we keep removing until readings and the board itself show dry, sound material, and we document anything beyond the original estimate before proceeding.

Do residents have to move out during sheathing replacement?

Usually not. The work happens from the outside. Openings are closed up or protected at the end of each day, and we coordinate with management on any unit access and on noise.

Does sheathing replacement need a permit in Sandy Springs?

Removing cladding and replacing sheathing or framing is more likely to require a permit than surface repairs. Check with the City of Sandy Springs building department for your scope before work starts.

Can a condominium association phase sheathing work?

Yes. We can prioritize the worst elevations and spread the rest over budget cycles. The survey and opening records help the board plan reserves.

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

Glass-mat gypsum sheathing resists moisture much better than paper-faced board and gives stucco and EIFS a stable substrate, which is why it is the common choice for commercial cladding today.
