Window Sill and Door Frame Rot Repair
Window sills and door frames are among the most common entry points for wood rot because they face weather exposure year after year without adequate caulking or paint maintenance. New Leaf removes compromised wood, treats the surrounding area, and rebuilds the sill or frame to match the original profile.
Signs You Need Window Sill and Door Frame Rot Repair
- A window sill that is soft, spongy, or crumbles when pressed with a screwdriver
- Paint that is peeling, bubbling, or blistering on a window or door frame
- Visible discoloration, darkening, or staining at the base of a window sill or door jamb
- Gaps forming between the window frame and surrounding trim where caulk has failed
- A door frame that is no longer square and is causing the door to stick or latch poorly
- Exterior door threshold that is soft or has separated from the floor or sill plate
Typical Cost Range
$500 - $600 per opening (minor) | $600 - $2,000 (major)
Based on rot extent, wood type, and whether frame is salvageable
Can rotted window sills be repaired with epoxy filler instead of replacement?
For surface rot that has not penetrated deeply, two-part epoxy wood filler can be a durable repair option. We probe the sill to determine how deep the rot goes before recommending filler versus replacement. If the rot has reached the structural members of the window buck or jack stud, the wood needs to come out.
Do you caulk and paint after a window sill or door frame repair?
Yes. All repaired wood is primed, caulked at seams and frame junctions, and painted to match. Skipping these steps after a rot repair allows moisture to re-enter and the cycle to start again.
How do I prevent my window sills from rotting again?
Keeping paint and caulk intact is the primary defense. Check caulk lines around windows annually and touch up any cracks or gaps before water can get behind them. Grading soil away from the foundation and keeping gutters clean also reduces the moisture load on window and door surrounds.
Exterior Trim and Siding Rot Repair
Exterior trim and siding rot typically begins at end grain, where paint and caulk have failed, allowing Cincinnati rain and humidity to penetrate over successive seasons. New Leaf removes affected boards, addresses the moisture pathway, and installs replacement material that matches the existing profile.
Signs You Need Exterior Trim and Siding Rot Repair
- Trim boards along rooflines, corners, or window surrounds that are soft to the touch
- Siding boards with visible cracks, cupping, or staining concentrated at the ends or lower edges
- Paint failure on wood siding or trim that returns quickly after repainting
- Boards that have separated from the wall surface, leaving a gap where water can enter
- Visible dark streaking or discoloration running down the siding from a failing board above
- Sheathing or housewrap visible through gaps in deteriorated siding boards
Typical Cost Range
$500 - $2,000 (spot repair) | $2,000 - $8,000+ (section replacement)
Varies by linear footage, siding type, and underlying sheathing condition
Do you replace the sheathing if it has been damaged by rot?
We inspect the sheathing behind siding once the affected boards are removed. If the sheathing is soft, compromised, or shows mold, we replace the damaged sections before installing new siding. Installing new siding over damaged sheathing leads to the same failure in a short time.
Can you match existing wood siding profiles?
Most standard wood siding profiles including clapboard, bevel siding, and trim board sizes are available at lumber suppliers. For discontinued or custom profiles, we mill or source as close a match as possible and disclose any visual difference before starting the repair.
Should I replace wood trim with a PVC or fiber cement product to avoid future rot?
PVC trim board and fiber cement are both excellent options for high-moisture or ground-contact areas that are prone to rot. They cost more than wood upfront but do not rot, hold paint well, and reduce maintenance over time. We can use rot-resistant alternatives in place of wood on any repair where it makes sense.
Structural Wood Rot Repair
Rot that has reached floor joists, rim joists, sill plates, or support beams requires careful assessment and staged repair to maintain structural integrity during the work. New Leaf approaches structural rot repairs methodically, replacing compromised framing and blocking while supporting adjacent structure as needed.
Signs You Need Structural Wood Rot Repair
- Floors that feel soft, springy, or bouncy in a localized area near an exterior wall or crawl space
- A rim joist or sill plate that is visibly deteriorated when viewed from a crawl space or basement
- Moisture intrusion in the crawl space or basement that has been ongoing for multiple seasons
- Joist hangers or beam connections that are pulling out because the wood beneath them has softened
- Visible mold or dark staining on framing members in a crawl space or basement
- An exterior door threshold with underlying sill plate rot that has caused the floor to drop or feel unstable
Typical Cost Range
$500 - $2,000 (joists/blocking) | $2,000 - $8,000+ (beam or sill plate)
Scope-dependent; requires assessment before final pricing
Do structural rot repairs require a permit in Cincinnati?
Structural repairs including sill plate and beam replacement typically require a permit in most Cincinnati-area municipalities. We clarify permit requirements during the consultation based on the specific scope and your jurisdiction, and can assist with the permitting process.
How is the structure supported during a sill plate or beam repair?
We use temporary jack posts or shoring to support the floor or roof load above the repair zone before removing compromised members. This keeps the structure stable and prevents movement while the new wood is installed and fastened.
Can structural rot repairs be done in a crawl space?
Yes. Crawl space access is a common part of sill plate and rim joist repairs. We use appropriate ventilation and protective equipment when working in confined crawl space environments and document conditions for the homeowner.
Deck and Porch Rot Repair
Deck and porch rot is common in the Greater Cincinnati area due to the region's humidity, rain, and freeze-thaw cycles. Decking boards, support posts, ledger boards, and joists are all vulnerable, and rot found in one area often signals moisture issues worth inspecting throughout the structure.
Signs You Need Deck and Porch Rot Repair
- Deck boards that are soft, spongy, or crumbling at the ends or along fastener lines
- Post bases that are dark, soft, or show visible rot at or below the deck surface
- A ledger board that is pulling away from the house or shows signs of moisture damage behind the flashing
- Joists that are visibly deteriorated or show dark staining when viewed from below the deck
- Porch flooring that flexes excessively underfoot, indicating joist or beam compromise
- Stair stringers that have cracked, softened, or shifted due to rot at the ground contact point
Typical Cost Range
$500 - $1,500 (spot repairs) | $1,500 - $6,000+ (structural replacement)
Based on rot location (decking, posts, ledger) and material
How do I know if my deck is safe to use if I suspect rot?
If you notice soft spots, excessive flex, or visible rot at posts or beams, limit use of the deck until it has been assessed. We can evaluate the structure and identify which members are compromised before recommending a repair scope.
Should I replace rotted deck boards with composite decking?
Composite decking is a practical option for rot-prone areas because it does not absorb moisture. It costs more than pressure-treated lumber but significantly reduces maintenance and future rot risk. We can install composite decking boards on existing framing when the structure itself is sound.
How is a rotted ledger board repaired?
Ledger repair involves removing the affected section, inspecting and drying the house wall behind it, installing or restoring proper flashing, and replacing the ledger board with pressure-treated lumber fastened per current code. The ledger connection is one of the most critical structural elements of an attached deck and needs to be done correctly.
