House wrap and moisture barrier installation protects the wall assembly behind your siding. It's easy to overlook because it's invisible once the project is done, but it's often the deciding factor in how well your exterior holds up.
Water stains inside can sometimes trace back to a failed or damaged barrier layer behind the siding.
Persistent musty smells can indicate trapped moisture behind the wall surface.
Any full removal is a natural point to inspect and refresh the barrier underneath.
If a repair reveals torn or degraded house wrap, that's worth addressing along with the siding itself.
Every new wall assembly needs a proper barrier installed as part of the original build.
House wrap and moisture barrier installation covers applying a water-resistant, vapor-permeable barrier to the wall sheathing before siding goes on. This layer is designed to let moisture vapor escape from within the wall while blocking liquid water from getting in, which is a balance that depends on correct installation, including proper overlap and sealed seams around windows, doors, and other penetrations.
This service applies both to new installations, where the barrier is part of the original build sequence, and to situations where an existing barrier is being repaired or replaced during a siding project.
The wall surface is checked for damage or moisture issues before any barrier material is applied.
Any compromised sheathing found is repaired first, since the barrier depends on a sound surface underneath.
House wrap is applied working from the bottom up, with proper overlap at every horizontal and vertical seam.
Windows, doors, and any other wall penetrations are properly flashed and sealed into the barrier system.
Every seam is checked before siding installation begins, since this layer becomes inaccessible once covered.
Once the barrier is confirmed properly installed, new or existing siding is installed over it.
Scope depends largely on whether this is a new installation or a repair situation. New construction and full re-sides involve barrier work across the entire home, while a targeted repair may only require addressing the barrier in one specific area where damage was found.
The condition of the sheathing underneath also plays a role, since any repair needed there has to be completed before the barrier goes on. We'll assess this directly during the on-site visit rather than estimating scope from a description alone.
Barrier materials are chosen and installed to their published performance specification.
Seams are overlapped correctly to maintain the barrier's water-shedding performance.
Windows, doors, and other openings are flashed and sealed to manufacturer standard.
Parts and labor coverage is provided in writing once the project is finished.
House wrap is typically a vapor-permeable material that blocks liquid water while allowing moisture vapor to escape, whereas a true vapor barrier is less permeable. Product choice depends on your wall assembly.
Sometimes, if the affected area is limited. Widespread barrier issues typically require broader siding removal to properly address.
Interior staining, musty odors, or visible damage during a repair are common indicators, though barrier condition often isn't visible without opening up the wall.
Yes, a proper house wrap is a standard part of every new siding installation we perform.
Improperly overlapped seams or unsealed penetrations can allow water intrusion, undermining the protection the barrier is meant to provide.
Barrier product selection depends more on your local climate and wall assembly than the siding material itself, though we'll recommend what fits your project.
Yes, both material and labor warranties apply, documented in writing once the project is complete.
Persistent trapped moisture behind a failed barrier can contribute to mold growth, which is part of why addressing barrier issues promptly matters.
