Cost to Install House Wrap Weather Barrier
Installing house wrap weather barrier means covering the home’s sheathing with a weather-resistant layer that directs water away from the structure. The work starts at the bottom of each wall and depends on consistent overlaps, sealed seams, and proper flashing around windows, doors, and other penetrations.
Common reasons homeowners do this job
- An existing weather barrier is worn.
- An existing weather barrier is damaged.
- An exterior-wall upgrade is underway.
- Water infiltration is a concern around windows, doors, or other penetrations.
- Damaged or protruding wall sheathing needs attention before a new barrier is installed.
DIY or call a pro?
This is a moderate DIY project, but a professional is worth considering if there is uncertainty about measuring wall area, maintaining the required overlaps, sealing seams and edges, or flashing penetrations. Use stable ladders or scaffolding, wear gloves and eye protection, and avoid installing house wrap in high winds or inclement weather.
Frequently asked questions
- Can I install house wrap myself, or is hiring help the better choice?
- A homeowner can take this on with a staple gun or hammer tacker, utility knife, tape measure, chalk line, and stable ladder or scaffolding. Consider professional help when the flashing details, seam sealing, or work at height feel beyond your comfort level.
- What makes house wrap installation cost more?
- The price scales with total wall area, labor time, and materials. Removing old material can add haul-away or disposal work, while a small wall section may be affected by a minimum or trip charge.
- How does house wrap keep water from getting behind the wall?
- Water shedding depends on starting at the bottom and overlapping every higher layer over the layer below. Seams and edges need manufacturer-approved seam tape, and windows, doors, and other penetrations need proper flashing to limit water infiltration.
- What should I check before buying house wrap?
- Measure the total wall surface area first so there is enough wrap. Inspect the sheathing for damage or protrusions, then review the manufacturer’s installation instructions for its overlap and fastener requirements before selecting cap staples or nails.
