DensGlass Sheathing Replacement in Newnan

Behind the facade

The damage is behind the finish

Behind every stucco or EIFS wall is a layer of sheathing fastened to the studs. On many commercial and multifamily buildings around Newnan that board is OSB, plywood or paper-faced gypsum. When water gets past a window perimeter, a parapet or a failed sealant joint, the sheathing absorbs it, and the cladding in front slows it from drying out. In humid west Georgia air, a wall that takes on water can stay damp for a long time.

Wood sheathing swells and delaminates, paper facings break down, and fasteners lose their hold. No coating or sealant fixes that from the outside. We remove the stucco or EIFS over the damaged area, cut the sheathing back to dry, sound board, check the framing behind it and install glass-mat gypsum sheathing, best known by the DensGlass name, in its place.

The new board is tied into the weather barrier and flashing so water that gets in later can drain out, and the stucco or EIFS is rebuilt and matched to the surrounding wall. Where framing is damaged, we identify it so the owner can bring in the right trade or engineer before we close the wall.

What we rebuild

Sheathing & substrate repairs in Newnan

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.

Sheathing damage in Newnan

Where we find wet sheathing around Newnan

Sheathing damage tends to cluster in a few places on Newnan buildings, and moisture readings usually confirm it before the wall is opened.

The buildings most at risk are those with barrier EIFS or older stucco details from the decades when Newnan’s commercial and apartment stock grew fastest. Water enters at windows, breezeways and roof lines, and the humid climate keeps it there. Georgia termites can add to the damage where wood framing stays wet.

Barrier EIFS buildings

No drainage behind the board, so every open joint sends water straight into the sheathing.

Breezeways & balconies

Apartment and condominium connections where ledgers, railings and door sills let water into the wall.

Termite-related damage

Wet wood framing and sheathing that termites have reached, repaired once the moisture source is stopped.

Questions & answers

Sheathing replacement FAQ for Newnan

Questions Newnan owners and managers ask when a wall has to be opened.

Does sheathing replacement need a permit in Newnan?

Replacing sheathing, and especially framing, often does. Requirements differ between the City of Newnan and unincorporated Coweta County, so check with the building department for your address. We provide the scope and details they need.

Will a Newnan inspector need to see the wall before it is closed?

If the work is permitted, the City of Newnan or Coweta County may require an inspection before the wall is closed, and we schedule around it. If we find damaged framing, the owner may also need a framing contractor or structural engineer before we rebuild.

How do you know how much sheathing is wet before opening the wall?

Moisture readings at probe points map the wet area. Once the wall is open, we cut back until we reach dry, sound board, so the final area can be larger or smaller than the readings suggested.

Why glass-mat gypsum instead of plywood or OSB?

Glass-mat gypsum sheathing resists moisture and mold far better than wood or paper-faced board, and it is widely used behind commercial stucco and EIFS.

Will the repaired area match the rest of the facade?

We match color and texture to the surrounding wall. On prominent elevations we may recommend recoating the full elevation so the repair does not show.
