Historic Home Wood Restoration

Older homes are built with irreplaceable materials — old-growth lumber, unique trim profiles, hand-built windows, and architectural details no longer in production. Preservan specializes in preserving original heritage elements rather than replacing them.

Why Historic Homeowners Trust Preservan:

  • We protect original craftsmanship instead of removing it
  • We replicate historic profiles using sculpting and millwork techniques
  • Our epoxy system reinforces aging lumber without altering its appearance
  • We avoid invasive demolition that can compromise historical value
 
Whether it’s a 1920s bungalow, a Victorian, or a mid-century home, we help preserve its identity — one careful repair at a time.

Termite & Insect-Damaged Wood Repair

Termites hollow out wood, leaving brittle surfaces that can fail without warning. Preservan’s restoration system stabilizes and rebuilds damaged fibers using a penetrating consolidator and structural epoxy designed for deep reinforcement.

Why Termite Infested Homeowners Trust Preservan:

  •  Termite tunneling and hollowed sills
  • Soft, crumbling door frames
  • Damaged porch posts and trim
  • Window components compromised by insect activity

 

We’ll also help identify moisture issues that attracted insects in the first place — preventing future damage and saving you thousands.

How Preservan’s Wood Rot Repair Works

Step 1: Assessment & Digital Quote

We inspect, document, and photograph all damage. You receive a clear, itemized digital estimate.

Step 2: Wood Stabilization & Rot Removal

We safely remove rotted fibers and stabilize anything salvageable using a marine-grade wood consolidator.

Step 3: Structural Epoxy Application

We rebuild missing or weakened sections using a chemical-bonding epoxy system that becomes stronger than the original lumber.

Step 4: Sculpting, Sanding & Finishing

We shape the repair to match original contours — perfect for windows, sills, casings, and decorative trim.

Step 5: Priming, Sealing & Protection

We finish the area with high-quality primer or stain to lock out future moisture.

Step 6: Final Walkthrough & Warranty

We review the project with you, share before/after photos, and activate your 10-year warranty.

FAQ: Wood Rot Repair

Can rotted window frames be repaired?

Yes — in most cases. Preservan’s epoxy restoration method allows us to permanently rebuild window sills without replacing the entire window. This saves time, money, and the hassle of matching existing windows.

Yes. Our system chemically bonds to the existing wood, creating a structurally superior, waterproof repair. With proper maintenance, epoxy repairs can outlast the surrounding lumber.
Common signs include:
  • Soft or spongy wood
  • Flaking or bubbling paint
  • Cracks, gaps, or discoloration
  • Musty or damp smells
  • Crumbly or hollow areas near windows or doors
If you’re unsure, we offer a free inspection.
Usually not. About 80–90% of wood rot cases are repairable without replacement — especially sills, sashes, jambs, and trim.
Most projects take 1 day, sometimes less. Larger or multi-area projects may take 2–3 days.
Yes. Our epoxy system stabilizes and strengthens termite-weakened wood, eliminating the need for major reconstruction in many cases.
Absolutely. We specialize in retaining original materials, profiles, and architectural character.
