The old patio door was drafty, hard to slide, and worn out after years of use. When we removed it, we found what many homeowners don’t see until it’s too late: serious wood rot in the framing beneath the door. We fixed the problem the right way, from the structure up, and installed a new energy-efficient door with better thermal performance.

- **Hardware:** Signature satin nickel handle with keyed lock
- **Screen:** Top-hung screen with BetterVue mesh for a clearer view
- **Finish:** Clean white inside and out
- **Ventilation:** AccuVent multi-venting system, so the door can lock while partially open for fresh air

 **What We Found: Hidden Wood Rot Under the Patio Door**

After the old door came out, we found significant rot in the wood framing below the opening. Water had been getting in for years, quietly weakening the structure. Many installers would cover this up with wood filler or simply set the new door on top of the damage. That’s not how we work.k

Our policy is simple: **Replace, Don’t Hide.** Before any repair began, we stopped work, walked the homeowner through the damage, and got their approval.

**How We Repaired the Rotted Framing**

 **1. Complete Removal of Damaged Wood**  
 We removed every piece of loose, rotted, and structurally compromised wood until we reached solid, healthy material.

**2. New Pressure-Treated Lumber**  
 We rebuilt the framing beneath the door with new pressure-treated lumber and structural fasteners, creating a strong, level base for the new patio door.

**3. Professional Flashing &amp; Waterproofing**  
 We installed OSI butyl self-adhesive flashing tape at the sill and transition points, layered shingle-style so water flows away from the house, not into it. We added sill protection where needed and integrated it with the existing water barrier.

 **4. Precision Installation**  
 We set the new door with laser leveling so it’s perfectly plumb, level, and square. Then we secured it with corrosion-resistant fasteners and composite shims, and insulated the full perimeter with low-expansion spray foam for an airtight seal.

 **5. Sealing &amp; Finishing**  
 We sealed the exterior with OSI QUAD MAX professional-grade sealant, finished the inside with new white casing, and installed clean, rot-resistant exterior trim.

The result is a patio door built on a solid foundation and properly sealed against water. It’s protected the way it should be, so the homeowner won’t face the same rot problem again.
