Wood Exterior Repair

Siding, trim, fascia, eaves, soffits — we stop deterioration at the source and restore your home’s exterior with precision-matched wood that blends seamlessly with existing profiles.

Exterior Restoration

Stop the Damage Before It Spreads

Exterior wood damage rarely stays contained. What starts as a small patch of soft siding or a cracked fascia board quickly becomes a pathway for moisture, termites, and dry rot to penetrate deeper into your home’s structural envelope. Left unchecked, cosmetic damage on the outside often leads to framing damage, mold growth, and far more expensive repairs behind the walls.

BPP Construction specializes in identifying the full extent of exterior wood damage, tracing it back to its source, and performing complete repairs that address both the visible deterioration and the underlying cause. With 35 years of experience working on homes throughout Riverside and San Bernardino counties, we have repaired every type of exterior wood issue Southern California homeowners encounter — from sun-bleached and cracked siding to termite-ravaged fascia boards to moisture-damaged eaves that have been silently deteriorating for years.

Every repair we perform uses lumber that matches the original dimensions, species, and grade of your existing woodwork. We do not take shortcuts with mismatched materials or quick-patch solutions that look obviously different from the rest of your home. The goal of every exterior repair is invisible integration — when we finish, you should not be able to tell where the old wood ends and the new wood begins. This attention to detail is what separates a professional repair from a patch job, and it is what protects your home’s curb appeal and resale value.

How We Restore Your Exterior

01

Comprehensive Assessment

We probe every square foot of affected area to determine the full extent of damage — not just what is visible on the surface. We identify moisture intrusion points, check for termite activity, test wood firmness behind paint, and assess whether structural members behind the exterior skin have been compromised. You receive an honest assessment and a clear scope of work before any repairs begin.

02

Source Elimination

Replacing damaged wood without fixing the cause guarantees the damage will return. We trace every deterioration pattern back to its origin — whether that is a failed flashing detail, a missing drip edge, a plumbing leak, poor grading that directs water toward the foundation, or a ventilation gap that traps moisture in the wall cavity. We correct the source before installing new material.

03

Precision Repair & Match

We remove damaged sections cleanly and install new lumber that matches the original profile, dimensions, and wood species. Every joint is tight, every transition is flush, and every surface is primed and prepared for finish coating. We use galvanized or stainless steel fasteners rated for exterior exposure and apply appropriate sealants at all vulnerable connection points to prevent future moisture entry.

What We Repair

Our exterior repair service covers every wood component on the outside of your home. We repair and replace horizontal lap siding, tongue-and-groove siding, board-and-batten siding, cedar shingle siding, fascia boards, barge boards, rake trim, corner boards, window trim and casing, door trim, eave soffits, porch columns, decorative brackets, exposed rafter tails, and any other exterior wood element that has suffered damage from moisture, sun exposure, insects, or age.

We also repair wood damage caused by failed paint coatings, improper caulking, deferred maintenance, and previous repair work that was done incorrectly. If a past contractor used the wrong lumber grade, left gaps at joints, or failed to properly flash transitions, we correct those deficiencies as part of our repair scope.

Common Questions

Wood Exterior Repair FAQs

Does exterior wood repair require a building permit in California?
In most California jurisdictions, minor cosmetic repairs like replacing a few siding boards or a section of trim do not require a permit. However, if the repair involves structural components — such as replacing load-bearing posts, repairing framing behind the exterior skin, or altering the building envelope in a way that affects weather resistance — a building permit is required under the California Building Code (CBC Title 24, Part 2). BPP Construction evaluates every project and pulls permits when required. We have 35 years of experience navigating the permitting process in Riverside and San Bernardino counties, and we maintain established relationships with local building officials to ensure smooth inspections.
What does California code require for exterior moisture protection?
The California Building Code requires a weather-resistant barrier behind all exterior wood cladding. Section R703.1 mandates that exterior walls provide weather protection for the building structure. This means all siding and trim installations must include proper flashing at windows, doors, and wall penetrations, a code-approved weather-resistant barrier such as building paper or house wrap, and appropriate clearance between wood components and the ground. When BPP Construction performs exterior repairs, we verify and restore all moisture protection layers — not just the visible wood surface. This comprehensive approach prevents the repaired area from developing the same moisture problems that caused the original damage.
How do I know if my exterior wood damage is cosmetic or structural?
Cosmetic damage is limited to the surface layer of exterior cladding — cracked paint, minor splits in siding boards, or surface-level weathering that has not penetrated into the wood fiber. Structural damage means the wood has lost its load-bearing capacity or its ability to protect the building envelope. Signs of structural damage include wood that is soft or spongy when probed with a screwdriver, visible fungal growth or dark discoloration indicating rot, framing members that flex or deflect under normal loads, and gaps that allow water behind the exterior surface. BPP Construction performs a thorough assessment using probing tools, moisture meters, and visual inspection techniques developed over 35 years to determine the full extent of damage and provide an accurate repair scope.
What type of lumber should be used for exterior wood repairs in Southern California?
The California Building Code requires that wood used in exterior applications be naturally durable or preservative-treated to resist decay and termite damage. For exterior siding and trim in the Riverside area, we typically use select-grade Douglas fir, western red cedar, or redwood depending on the existing materials and exposure conditions. All lumber in contact with or within six inches of the ground must be pressure-treated per CBC Section R317.1. We match the species, grade, and dimensions of your existing woodwork to ensure visual consistency and structural compatibility. Using the wrong lumber type is one of the most common mistakes we see in previous repair work — it leads to differential expansion, mismatched weathering patterns, and premature failure.
Can exterior wood damage indicate a termite infestation that needs to be addressed?
Yes, and in Southern California this is extremely common. Drywood termites and subterranean termites are both prevalent in the Riverside and San Bernardino county areas. Signs of termite damage in exterior wood include small piles of frass (termite droppings that look like sawdust), hollow-sounding wood when tapped, visible mud tubes on foundation walls, and wood that crumbles when probed. California Civil Code Section 1099 requires sellers to provide a Wood Destroying Pest and Organisms Inspection Report during real estate transactions, but proactive inspection and repair protects your investment year-round. BPP Construction identifies termite damage during our assessment and coordinates with licensed pest control professionals when active infestations are present, ensuring the infestation is treated before we install new material.
How does BPP Construction ensure repaired sections match the rest of my home?
Profile matching is one of the most critical aspects of exterior wood repair, and it is where many contractors fall short. We start by identifying the exact siding profile, trim dimensions, and wood species used on your home. For common profiles, we source matching stock from specialty lumber suppliers. For discontinued or custom profiles, we can have matching pieces milled to replicate your existing woodwork exactly. We also carefully plan transition points so that joints between old and new material fall at natural break points — inside corners, butt joints at stud locations, or behind downspouts and trim pieces. Once installed, new wood is primed on all six sides before finish coating to prevent future moisture absorption, and finish paint is applied to blend seamlessly with adjacent surfaces.
