Deck repair FAQ
Common questions about deck repair in the Niagara Region.
How much does deck repair cost in the Niagara Region?+
Small deck repairs like tightening railings, replacing a few boards or re-securing stairs typically start around $200–$400. Structural repairs, post replacement, stair rebuilds and larger surface replacements are priced by materials and labour. Send a few photos by text or email and we'll come back with a clear ballpark same-day or next-day.
Can you replace rotted deck boards without rebuilding the whole deck?+
Yes — this is one of our most common jobs. We lift the damaged boards, inspect the joists underneath to confirm they're dry and sound, then install matching pressure-treated or composite replacement boards. If any joists are compromised, we sister or replace those too so the repair lasts.
Do you repair deck railings and stairs?+
Absolutely. Loose railings are re-secured with proper lag bolts and blocking, wobbly posts reinforced or replaced, and damaged stair treads and stringers rebuilt. We also check railing height and picket spacing to make sure everything meets current safety standards.
Can you repair rental property decks between tenants?+
Yes — rotted boards, loose railings and structural issues are common turnover problems, especially in older rentals across St. Catharines, Welland and Niagara Falls. We document with before/after photos and provide itemized invoices that work for security deposit deductions or insurance claims.
How do I know if my deck needs repair or full replacement?+
If the underlying structure — posts, beams and joists — is sound, targeted repairs usually add many years of life. Signs that repair is enough: isolated rot in surface boards, loose hardware, faded stain and minor railing issues. We inspect honestly and tell you before quoting.
Can deck repair be combined with fence or exterior work?+
Yes. Deck repair pairs naturally with our fence repair, exterior paint and rental turnover services — one crew, one schedule, one invoice. Many Niagara landlords have us handle deck, fence and exterior paint in a single visit between tenants.
What areas of the Niagara Region do you cover?+
St. Catharines, Niagara Falls, Thorold, Welland, Fort Erie, Port Colborne, Wainfleet, Niagara-on-the-Lake and surrounding communities. If you have multiple properties across the region, we can roll service calls together.
