- Wood is the most common material in older South Florida homes — and the most vulnerable to the region’s humidity, salt air, and year-round UV exposure. Rotten window frames, deteriorated sills, swollen door casings, and failing fascia boards are everyday findings on homes throughout Palm Beach and Broward counties. Atlantic Window Repair operates an in-house woodworking workshop, which means we fabricate, restore, and replace wood components ourselves — no subcontractors, faster turnaround, and direct accountability for the finished result.
Rotten Windows Repair
Rot in window frames and sills typically starts where paint has cracked or caulk has failed — moisture gets in and breaks down the wood fiber from the inside. Left unaddressed, what starts as a soft spot spreads into the surrounding frame, the rough opening, and eventually the wall structure. Early intervention costs far less than frame replacement, and frame replacement costs far less than structural remediation.
Our rotten window repair process:
- Probe and assess the extent of rot before quoting — no surprises on-site
- Remove deteriorated wood fiber and dry the area thoroughly
- Apply penetrating epoxy consolidant to harden remaining sound wood
- Fill voids with two-part epoxy filler, shaped to match the original profile
- Sand, prime, and apply a finish coat matched to the surrounding surface
- Seal all joints with weather-resistant caulk to prevent re-entry of moisture
Rot that keeps coming back is usually a sealant problem rather than a wood problem, and window caulking service is what stops the water getting behind the frame in the first place.
When rot has compromised structural integrity — meaning the frame no longer holds the sash securely or has allowed water behind the wall — we replace the affected frame sections or the full frame rather than filling over a compromised substrate. We make that determination on-site and explain the reasoning before any work begins. Where the unit is past saving as a unit, the work continues as new window installation with the opening rebuilt to take it.
Wood Window Restoration
Restoration differs from repair: the goal is to return a deteriorated wood window to full function and original appearance without replacing it. This is particularly relevant for historic homes, Mediterranean Revival and mid-century properties throughout Boca Raton and Delray Beach, where original wood windows have architectural character that standard replacement units cannot replicate.
Wood window restoration includes stripping failed paint and glazing compound, re-puttying the glass, replacing broken sash cords and weights, repairing or replacing hardware, and refinishing the entire unit to a weathertight condition. When sash components have deteriorated beyond repair, our in-house workshop fabricates replacements to match the original profiles. Where the old pane is cracked, single pane glass replacement into the restored sash finishes the job.
A properly restored wood window, sealed and maintained, will outlast most vinyl replacement units in a coastal climate. We work with pine, mahogany, and cypress depending on the application and the client’s preference for longevity vs. cost.
Sometimes the wood is fine and only the glass has gone. Both get handled in one visit. We repair the sash and re-putty it, and the pane goes in as glass replacement.
Rotted Fascia Board Repair
Fascia boards are the horizontal boards that run along the roofline and close off the rafter ends. In South Florida, they are almost always painted wood — and among the first exterior components to show rot, particularly where gutters overflow or where roof flashing has failed. Compromised fascia is both a cosmetic problem and a structural one: water that passes behind the fascia board reaches the sub-fascia, rafter tails, and wall framing.
We remove rotted fascia sections, inspect and treat the sub-fascia and rafter ends, install replacement boards in matching width and profile, prime all cut ends before installation, and finish with an exterior-grade paint coat. Where the existing profile is non-standard, our workshop mills replacement stock to match.
Fascia repair is frequently combined with window casing and exterior trim work — if the fascia is failing, the window casings on the same elevation are often in similar condition. We assess the full elevation and quote the combined scope where it makes sense.
Custom Millwork and Exterior Trim
Our in-house workshop produces custom wood components that are no longer available off the shelf — a requirement on older homes, historic properties, and high-end custom builds where standard profiles do not match existing architectural details. Millwork capability also means that when a single damaged piece needs replacement, we fabricate the exact profile rather than substituting something close.
Custom millwork we regularly produce:
- Replacement sash components for historic and non-standard windows
- Window sills and stool profiles matched to existing dimensions
- Interior and exterior casings matched to original molding patterns
- Wood grilles and muntin bars for multi-lite windows
- Door thresholds, sweeps, and astragals
- Custom exterior trim, corbels, and decorative elements
- Sub-sill and pan flashing components in wood or composite
We work from measurements, drawings, or photos of the original. For historical restoration projects requiring documented profiles, we can work with preservation guidelines and HOA specifications.
Frequently Asked Questions
Can rotted window frames be repaired without replacing the whole window?
Often yes. If the rot is localized and hasn’t compromised the frame’s ability to hold the sash or glass securely, epoxy consolidation and fill is an effective long-term repair. We assess each situation on-site before recommending repair vs. replacement — the determining factor is structural integrity, not the appearance of the damage.
How do I know if my fascia boards need repair or full replacement?
A fascia board that feels soft when probed, shows visible rot or crumbling wood fiber, or has pulled away from the sub-fascia needs replacement rather than surface treatment. Boards with surface paint failure and no structural softness can sometimes be sanded, primed, and repainted. We probe and assess before quoting so you know which category you’re dealing with.
What wood species do you use for repairs and replacements?
We work with pine, mahogany, and cypress. For coastal applications where the wood will be exposed to driven rain and salt air, we typically recommend cypress or a composite material for superior rot resistance. For interior millwork or painted exterior trim, pine is the standard choice. Mahogany is appropriate for high-end or historically accurate restorations.
Do you paint or finish after woodwork repairs?
We do, yes. All exterior woodwork repairs include priming and a finish coat matched to the surrounding surface color. For stained wood, we match the stain as closely as possible. We do not leave bare wood or primer exposed — the weatherproofing of the repair depends on a proper sealed finish.
Can you replicate custom or historic window profiles?
Yes, we can. Our in-house workshop can fabricate custom profiles to match existing historical or non-standard millwork. We work from measurements, existing pieces, or photographs. For complete sash reproduction, we need the original unit on-site or detailed dimensions of all profile elements.
How much does wood window or rot repair cost in Boca Raton?
Cost depends on how far the rot has spread, which we can only confirm by probing the actual wood on-site. Localized epoxy repair costs far less than replacing a frame section, and a frame section costs far less than structural repair once water reaches the wall. We give a written price at the free on-site assessment.
Do you repair wood doors and door casings, not just windows?
We repair and rebuild rotted wood door casings, jambs, and thresholds and mill custom replacement pieces in our own workshop when the profile is non-standard. The same epoxy and millwork methods we use on windows apply to wood doors.
