Fence and Deck Building & Repair Experts
For small, surface-level repairs (tightening railings, replacing a few boards, re-securing stairs), Niagara-area pricing typically starts around $200-$400, quoted from photos. More generally across Ontario, minor deck repairs run roughly $10-$50 per square foot. Structural repair work (a compromised ledger board, joists, beams, or posts) is a different category, and we have not found a reliable Niagara or Ontario $ range to quote for it, honestly -- it depends heavily on scope, and pricing that kind of work by a fixed range would be a guess, not a real number. Book an honest, straightforward assessment and we will tell you what the actual scope looks like before any work begins.
The common-industry answer, and it is a genuine practitioner consensus rather than one source's opinion: replacing surface boards, fasteners, or railings on a deck whose underlying frame is sound generally does not require a building permit. Repairing structural elements -- the ledger board, joists, beams, posts, or footings -- generally does, the same way a new deck's structural work would. That said, this is a genuinely different, less settled question than a new build's permit rules. We checked directly, and Niagara Falls' own official list of projects that do not need a building permit names specific like-for-like exemptions -- re-shingling a roof with the same materials, replacing windows to the same size -- but does not mention deck repair at all, in either direction. That is silence, not a stated exemption and not a stated requirement. So the honest instruction here is the general rule above, plus this: confirm with your municipality before starting structural repair work, since no Niagara-specific repair-permit rule is published to point to. For the new-build permit thresholds that ARE directly codified per municipality, see the Niagara deck permit guide -- that is a separate, more settled question than this one.
The honest first question on any deck repair is whether it should be a repair at all. Two decision factors do most of the work. First, where the damage is: isolated rot in surface boards, loose hardware, or minor railing issues on a frame that is otherwise sound is repair territory. Damage that reaches the ledger board, joists, beams, posts, or footings generally means replacement, because at that point what looks like a repair is functionally a partial rebuild -- removing deck boards and fascia, exposing and often replacing the ledger, checking the house rim joist behind it, and reinstalling flashing and hangers. Second, a practical field test worth knowing: press a screwdriver tip into a joist, post, or the ledger board. If it sinks more than about a quarter inch without resistance, that wood is structurally compromised. A visible gap between the ledger and the house, water staining, soft wood, or failed flashing underneath the ledger are all safety red flags worth an honest look before anything else. There is also a rougher, longer-range heuristic worth knowing, stated honestly as an informal industry rule of thumb rather than a fixed number: when repair costs start approaching what a full replacement would cost, replacement is usually the better call. Typical material lifespans give some sense of where a deck sits on that curve -- pressure-treated wood commonly lasts 15-25 years, cedar and redwood 15-20 years, composite 25-30 years, and capped composite or PVC 30-plus years -- so an older deck needing significant work is a different conversation than a newer one with an isolated problem. None of this replaces an actual look at your deck. That is exactly what the honest, straightforward assessment is for.
It depends on where the damage is. Isolated rot in surface boards, loose hardware, or minor railing issues on an otherwise sound frame is usually a repair. Damage reaching the ledger board, joists, beams, posts, or footings is usually a replacement, because that level of work functions as a partial rebuild either way. A rough industry rule of thumb: once repair costs start approaching what a full replacement would cost, replacement is generally the better call.
A simple field test: press a screwdriver tip into a joist, post, or the ledger board. If it sinks more than about a quarter inch without resistance, that wood is structurally compromised. A visible gap between the ledger and the house, water staining, soft wood, or failed flashing under the ledger are also red flags worth an honest look.

The general practitioner rule: surface repairs (boards, fasteners, railings) usually do not need a permit; structural repairs (ledger, joists, beams, posts, footings) usually do, similar to a new build. This is a less settled question than new-build permit rules, though -- Niagara Falls' own official permit-exemption list does not name deck repair in either direction. Confirm with your municipality before starting structural repair work.
The ledger board is the piece that attaches the deck to the house. Damage here -- a visible gap, water staining, soft wood, or failed flashing underneath -- is one of the highest-stakes signals on a deck, because ledger repair usually means removing boards and fascia, exposing and often replacing the ledger itself, checking the house rim joist behind it, and reinstalling flashing and hangers. At that point, "repair" is functionally a partial rebuild.
Yes -- with an honest, straightforward assessment before any work begins, so you know whether you are looking at a real repair or something closer to a rebuild before any work starts.
