Behind the facade

When the problem is behind the cladding

A soft spot below a window, cladding that bulges between joints, or moisture readings that stay high after a dry week are signs that the sheathing behind a facade has been taking on water. On Milton buildings from the late 1990s and 2000s, that sheathing is often OSB, plywood or paper-faced gypsum, all of which lose strength once they stay wet.

Sheathing cannot be dried out or sealed from the surface. The repair is to remove the cladding over the damaged area, cut out the wet board back to dry material, and inspect the studs and framing behind it. Damaged framing is reported to you and repaired before closing up.

We install glass-mat gypsum sheathing, commonly known by the brand DensGlass, because its fiberglass facing does not feed mold and tolerates moisture far better than paper-faced board or wood panels. The new board is tied into the surrounding sheathing, the weather barrier is lapped into what remains, flashing at windows is corrected, and the stucco or EIFS is rebuilt and finished to match the rest of the wall.

What we rebuild

Sheathing & substrate repairs in Milton

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.

Substrate repair in Milton

Wooded sites, wetter walls

Milton's tree cover is part of its appeal. It also changes how long a wall stays wet and what can get into it.

Many Milton commercial and multifamily buildings sit near tree lines and planted buffers. Walls on those shaded sides dry slowly after rain, leaf litter and mulch build up against the base, and irrigation often sprays the lowest course of cladding. Termites are a fact of life in Georgia, and wood sheathing that stays damp near soil gives them an easy route. When we open a wall in these conditions, we look for both water and termite damage and report what we find.

Shaded elevations

Walls along tree lines that stay wet longer and show substrate damage first.

Termite damage

Damaged sheathing and framing documented and replaced; treatment coordinated with your pest provider.

Mapped readings

Moisture readings define where the wall is opened, so removal stays as small as possible.

Questions & answers

Sheathing replacement questions from Milton

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

Does sheathing replacement on a Milton building need a permit?

Work that opens walls and replaces sheathing or framing may require a permit. Check with the City of Milton's building department for your scope; we provide a written description of the work.

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 of it. We use glass-mat gypsum board because it handles moisture better than paper-faced gypsum or wood panels.

How do we know the sheathing behind our facade is damaged?

Moisture readings taken through small probe holes at windows, joints and the base of walls show where the substrate is wet. Soft or bulging cladding is another sign. We map readings before recommending any removal.

Do you have to remove the cladding from the whole building?

Usually not. We remove cladding only where readings and probing show damage, then extend the opening until we reach dry, sound board.

Can our Milton tenants or residents stay in place during the work?

Yes. Openings are kept as small as possible, the wall is protected from weather while open, and work is phased so occupied spaces are not left exposed.

How is sheathing replacement priced?

By the area of cladding removed and rebuilt, the sheathing and framing replaced, flashing corrections, finish matching and access. Hidden framing damage is priced as found, and we explain how before work starts.
