Deck Repair and Staining Cost Guide for Handymen
Price deck board replacement at $15–$35 per board, railing repairs at $100–$300 per section, and structural repairs at $200–$500+. Deck staining runs $2–$4 per square foot for labor and materials. A typical 300-square-foot deck staining job should be quoted at $600–$1,200. Always inspect the substructure before quoting surface-level repairs.
Deck repair and staining is seasonal gold for handymen — demand spikes every spring as homeowners prepare their outdoor spaces. The work ranges from simple board replacements to full railing rebuilds and refinishing. Pricing deck work accurately requires understanding material differences between pressure-treated lumber, cedar, and composite decking, and knowing when a repair job is actually a rebuild that should be referred to a deck contractor.
Deck Board Replacement Pricing
Individual deck board replacement is straightforward and profitable. Pressure-treated 5/4x6 decking boards cost $1.50–$3.00 per linear foot, and cedar runs $3–$6 per linear foot. Composite boards from Trex, TimberTech, or Fiberon cost $5–$12 per linear foot. Charge $15–$35 per board for removal and replacement, depending on length and material. For composite decking, add a premium because hidden fastener systems (like Trex Hideaway clips or Camo screws) take longer to work with. When replacing boards, always check the joists underneath — a rotted board often means moisture damage to the joist below. If you find joist damage, add $75–$200 per joist for sistering (bolting a new joist alongside the damaged one) or full replacement. Carry a few common board sizes in your truck for same-day repairs.
Railing Repair and Replacement
Railing repairs range from tightening loose balusters to rebuilding entire sections. Tightening or replacing individual balusters (spindles) costs $10–$20 each — a quick job with excellent margins. Replacing a full railing section (6–8 feet of rail with balusters) runs $150–$350 depending on material and style. Code compliance is critical for railings: residential deck railings must be 36 inches high (42 inches in some jurisdictions), with balusters spaced no more than 4 inches apart. If you are replacing a railing, bring it up to current code — this protects you from liability and adds value for the client. Pre-made railing kits from Deckorators or Fiberon simplify installation and come in wood, composite, and aluminum options. Aluminum rail sections cost $50–$100 per 6-foot section and install quickly with bracket mounting.
Structural and Substructure Repairs
Structural deck repairs include joist repair, beam replacement, post replacement, ledger board issues, and footing work. These are higher-complexity jobs that command premium pricing. Joist sistering costs $75–$200 per joist — bolt a new pressure-treated joist alongside the damaged one using structural lag bolts or carriage bolts. Post replacement runs $150–$350 per post including the footing. Ledger board issues (where the deck attaches to the house) are serious safety concerns — if the ledger is pulling away, the entire deck is at risk of collapse. Ledger repair or replacement costs $300–$800 and often requires removing and reattaching the deck framing. Know your limits: if the substructure has widespread rot or structural failure, refer the job to a licensed contractor. Document the damage with photos and explain the safety concern clearly to the client.
Deck Staining and Sealing Pricing
Deck staining is one of the most profitable handyman services when priced correctly. Charge $2–$4 per square foot for staining, which includes surface preparation (cleaning, sanding, and light repair) plus one coat of stain. A 300-square-foot deck runs $600–$1,200 for a complete refinish. Premium stains like Cabot Australian Timber Oil ($40–$55 per gallon), TWP 1500 Series ($45–$60 per gallon), or Armstrong-Clark ($50–$65 per gallon) cover 150–250 square feet per gallon and last 2–4 years. Budget 2–3 gallons for a 300-square-foot deck. Solid stains provide more coverage and hide imperfections but peel over time, while semi-transparent stains show the wood grain and wear more gracefully. Recommend semi-transparent for well-maintained decks and solid for older or heavily repaired surfaces.
Surface Preparation and Cleaning
Proper surface prep is 60% of a good stain job and should be priced accordingly. Pressure washing the deck before staining costs $75–$150 as a standalone service (see pressure-washing-pricing for details). Use a deck cleaner/brightener like Behr Premium All-in-One Wood Cleaner or Olympic Premium Deck Cleaner ($15–$25 per gallon) before washing. For previously stained decks, you may need to strip the old finish with a chemical stripper ($20–$35 per gallon) — add $1–$2 per square foot for stripping. After washing, the deck needs 24–48 hours to dry before staining. Light sanding with 60–80 grit paper on a pole sander smooths raised grain and helps stain adhesion. Factor in this multi-day timeline when scheduling — you cannot wash and stain the same day.
Composite Deck Maintenance and Repair
Composite decking (Trex, TimberTech, Azek, Fiberon) requires different maintenance than wood. Composite does not need staining, but it does need cleaning — charge $0.50–$1.00 per square foot for composite deck cleaning using manufacturer-recommended cleaners. Scratches on composite can be repaired with a heat gun technique for uncapped boards or touch-up kits from the manufacturer — charge $25–$50 per repair. Board replacement on composite decks is more expensive due to material cost ($5–$12 per linear foot) and hidden fastener systems. One challenge: matching color on aged composite boards is difficult because UV exposure changes the color over time. Recommend replacing boards in pairs or full sections for a consistent appearance. Some manufacturers like Trex offer individual board replacements through their warranty program — check if the deck is still covered before quoting.
