Behind the facade

The damage is behind the wall

Mid-rise offices, hotels and multifamily buildings in Dunwoody often have gypsum sheathing behind their stucco or EIFS. Older buildings may have paper-faced gypsum, which loses strength fast when wet; newer ones usually have glass-mat products such as DensGlass. Either can be damaged by years of slow leaks at window perimeters, parapets and joints.

From the outside, the signs are subtle: EIFS that flexes when pressed, cracking along board joints, staining below windows or a wall that sounds different when tapped. Inside, tenants and residents may notice musty odors, stained drywall or recurring leaks that repairs have not fixed.

We start with moisture readings to map where the sheathing is wet, and open test areas to confirm what we find. The cladding is then removed only in damaged areas, the wet sheathing is cut back to dry material, and any damaged framing is reported and repaired. New glass-mat gypsum sheathing is installed, a weather barrier is lapped into the surrounding wall and into window flashing, and the stucco or EIFS is rebuilt and finished to match. Correcting the original leak path, usually a sealant or flashing detail, is part of every scope.

What we rebuild

Sheathing & substrate repairs in Dunwoody

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.

Behind Dunwoody’s facades

Occupied buildings, open walls

Replacing sheathing means opening the wall of a building people are using. We plan for that first.

In Dunwoody, sheathing replacement usually happens on buildings that stay open: offices with tenants working behind the wall, hotels with guests, and apartment and condo buildings with residents in their units. We open only what can be closed the same day or protected overnight, keep the interior weathertight, and coordinate with property managers on noise, dust and access to units or suites when interior inspection is needed.

Offices & hotels

Sheathing replacement on mid-rise buildings, phased so guests and tenants are not disturbed.

Multifamily buildings

Wet substrate at balconies, breezeways and windows replaced unit stack by unit stack.

Framing & termite damage

Damaged studs and plates found behind the sheathing reported and repaired before the wall is closed.

Questions & answers

Sheathing questions from Dunwoody properties

What Dunwoody owners, managers and boards ask when sheathing damage is suspected.

What is DensGlass, and is it the same as denglass?
DensGlass is a brand of glass-mat gypsum sheathing, and denglass is a common misspelling. Glass-mat sheathing resists moisture better than paper-faced gypsum, which is why it is used behind stucco and EIFS.
How do we know if the sheathing on our Dunwoody building is damaged?
Soft or flexing EIFS, cracks along board joints, staining under windows and recurring interior leaks are common signs. A moisture survey with targeted openings confirms it.
Can the building stay occupied during sheathing replacement?
Yes. We open limited areas at a time, keep the building weathertight and coordinate noise and access with the property manager.
Does sheathing replacement in Dunwoody need a permit?
Work that removes cladding and replaces sheathing or framing often does. Check with the City of Dunwoody building department about your scope; we provide written scope details for the application.
What if the framing is damaged too?
We document framing damage with photos as it is uncovered and discuss the repair before closing the wall. Framing repairs are priced as described in the quote.
How is sheathing replacement priced?
By the area of cladding removed and rebuilt, the extent of sheathing and framing damage, access and finish matching. We provide a written, itemized quote, with unit pricing for hidden conditions.
