DensGlass Sheathing Replacement in Marietta

When water has been getting behind stucco or EIFS on a Marietta building for years, the sheathing is usually where the real damage is. We open the wall, replace soft or rotted sheathing with glass-mat gypsum board, repair framing as needed and rebuild the cladding.

Behind the facade

What a Marietta recoat can uncover

Many sheathing problems in Marietta are found by accident. An owner plans a facade refresh on an older apartment community or office building, the crew starts preparing the wall, and a section of EIFS gives under a hand or a probe goes straight through the board behind it. Decades of slow leaks at windows and joints have turned the original sheathing soft, and sometimes the framing behind it too.

That damage cannot be repaired from the outside. We remove the cladding in the affected area, cut back to dry, sound sheathing, and check the framing for rot or termite damage. Damaged studs and plates are repaired. New glass-mat gypsum sheathing goes in, followed by a weather barrier lapped into the existing barrier and flashing at the window or detail that caused the leak. Then we rebuild stucco or EIFS and finish it to match.

The best time to find this is before a recoat, not after. A moisture survey shows where the sheathing is wet so the budget and schedule include it from the start.

What we rebuild

Sheathing & substrate repairs in Marietta

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.

Hidden damage in Marietta

Older Marietta buildings hide wet sheathing

The buildings most likely to need sheathing work here are the ones that have gone longest without envelope maintenance.

Garden-style apartment communities and condominiums from the 1980s and 1990s, and office buildings of the same age along Marietta’s east-side corridors, often have original sheathing behind barrier EIFS or stucco. Where window flashing was never installed, the damage tends to be concentrated below window corners and along balconies and breezeways. We map it with moisture readings so the repair is limited to the walls that actually need it.

Find it first

Moisture readings below windows, at balconies and along the base of the wall before any work is priced.

Framing & termites

Rotted or termite-damaged studs and plates repaired once the wall is open.

Rebuilt right

Glass-mat gypsum board, lapped weather barrier and flashing, then matched cladding.

Questions & answers

Sheathing replacement FAQ for Marietta

What Marietta owners and managers ask when damage is found behind the wall.

Does replacing sheathing on a Marietta building need a permit?

Opening walls and replacing sheathing or framing usually goes beyond maintenance. Whether a permit is required depends on the scope and whether the property is in the City of Marietta or unincorporated Cobb County. Check with that building department; we will provide a written scope to support the application.

Can residents or tenants stay in their units while you replace sheathing?

In most cases, yes. We open one area at a time, close it in the same day or protect it overnight, and coordinate with management about interior protection where the wall is open.

What is DensGlass?

DensGlass is a brand name for glass-mat gypsum sheathing, a board with fiberglass facings instead of paper. It resists moisture and mold better than paper-faced board, which is why it is commonly used behind stucco and EIFS.

How do you know how much sheathing to replace?

Moisture readings map the wet areas before work starts. Once the wall is open, we cut back to sound, dry board and document what we find with photos.

Will the new section match the rest of the wall?

We match color and texture, and on weathered walls we may recommend recoating to a corner or joint so the repair blends in.
