Boards flex or feel soft
Softness can indicate prolonged moisture exposure.
Deck condition and repair
Deck repair and resurfacing across the Greater Toronto Area
Something has gone wrong with your deck and you want to know how serious it is. Send photos of what you can see.
We'll explain what the photos suggest, what needs an on-site assessment, and whether repair, resurfacing, or replacement makes sense.
Photos and rough measurements help. Include a survey or drawing if you have one.
Signs your deck needs an assessment
Some warning signs are cosmetic and others are structural. The difference may not be visible from above.
Boards split, cup, or lift
The damage may be limited to the surface, but the fasteners underneath should also be checked.
A railing moves
A guard that shifts under pressure is a safety issue, not routine maintenance.
Stairs flex or a tread is loose
Stairs take concentrated loads, so their support and connections need checking.
Fasteners rust or back out
Visible corrosion or movement can show that connections are loosening.
The deck sways or bounces
Movement may involve posts, beams, footings, or the house connection.
Staining or rot appears at the house
The ledger and surrounding flashing need attention because damage here can stay hidden from above.
The surface looks grey and worn
Weathering can be cosmetic, but it often prompts questions about resurfacing.
If a guard gives, a stair moves, or structural damage is visible, stop using the deck until it has been assessed.
Photos help identify what to inspect, but they do not replace an on-site assessment. Do not enter an unsafe area to take them.
Repair, resurface, or replace?
There is no square-footage threshold. The decision depends on what is failing.
| What is going on | Where it may point | Why |
|---|---|---|
| A few damaged boards with sound framing | Repair | Individual boards can be replaced when the structure below is sound |
| A loose railing, stair, or hardware item | Repair | Component work may be suitable when its supporting structure is sound |
| A worn surface with a sound frame | Re-decking or another resurfacing method | The frame may remain while the surface is addressed |
| Localized frame or footing damage | Assessment needed | Some framing can be reached and repaired in place; other damage requires wider removal |
| Frame movement, widespread deterioration, or failing footings | Replacement may be better | Repair costs can approach a rebuild without delivering the same usable result |
| Material is unavailable to match | Depends on visibility and goals | A repair may remain possible, but you should understand the mismatch first |
| The deck is sound but the layout no longer works | Replacement | This is a design decision rather than a condition problem |
What resurfacing means
Re-decking replaces the boards while keeping a sound frame. Refinishing cleans, sands, and re-stains existing boards. A coating covers the existing surface. The work, cost, and result differ, so our written scope names the method.
What we look at
We assess the deck from above and underneath.
Surface and fasteners
We check which boards are failing, how far the damage spreads, why it developed, and whether fasteners or hardware are corroding or loosening.
Frame
We check joists, beams, and posts, including whether damage is localized or widespread. Frame condition helps determine whether repair or replacement makes sense.
House connection
On an attached deck, we inspect the ledger and surrounding flashing detail for movement and water damage.
Footings
We look for movement, settlement, or deterioration and assess whether the footings can support the proposed work.
Stairs and guards
We review stringers, treads, risers, landings, posts, rails, and the connections that hold them rigid.
Material matching
We check whether replacement boards remain available and explain how visible a mismatch may be.
We'll explain what we found, what remains hidden, and what each option involves. If repair does not make economic sense, we'll say so.
Where surface work ends and structural work starts
| Scope | What it means | What it does not do |
|---|---|---|
| Board replacement | Replace failed boards on a sound frame | Does not address framing, footings, or the house connection |
| Full surface replacement | Install new decking while retaining the frame | Requires the frame to be assessed and suitable for the new surface |
| Stair work | Repair or replace treads, stringers, landings, and handrails | A moving stair may point to a footing or frame problem |
| Guard and railing work | Repair posts, rails, infill, and connections | A guard remains dependent on the framing supporting it |
| Localized framing work | Address joists, beams, or posts in a defined area | Does not replace widespread structural work |
| Fastener and hardware work | Secure or replace corroded or loose connections | Cannot restore wood that has deteriorated |
Pool-enclosure fence and gate work remains a separate safety scope. See pool fencing. Damage to a fence belongs with fence repair.
What can change once we open it up
Some damage is only visible after boards come off.
Joist tops sit under the boards, the ledger meets the wall behind finished surfaces, and footings extend below grade. A deck can look sound from above while hiding damage, or look worn on top while retaining a sound frame.
We assess visible conditions and prepare a scope. If opening the deck reveals something different, we stop, document it, show you, and agree on a revised scope before continuing. Additional work will not appear on an invoice unless you approve it first.
We cannot promise frame reuse before an on-site assessment.
When repair work needs approval
Permit requirements depend on the repair scope and municipality.
Confirm the written scope with your municipality, especially if work alters framing, changes the deck's size or height, or rebuilds stairs in a different configuration. Toronto's decks and porches guide explains its application requirements.
- Confirm whether the written scope needs approval and who makes that determination.
- Record who applies, answers comments, books inspections, and corrects any deficiencies.
What affects a deck repair quote
| Factor | Why it moves the price |
|---|---|
| Area affected | A few boards and a whole surface are different jobs |
| Component and location | Surface, stairs, guards, framing, footings, perimeter, and ledger areas require different access |
| Deck height | Low clearances and elevated work each add access requirements |
| Material matching | Availability and the acceptable visibility of a mismatch |
| Hidden conditions | Damage found after the surface is opened |
| Disposal and site access | How failed material leaves and new material reaches the work area |
| Approvals | Municipal steps required by the final scope |
| Repair versus replacement | At some point replacement may become the better scope; we explain when the assessment reaches that point |

Show the damage, stairs, railings, house connection, and underside where safely reachable.
- 2
Photo review
We explain what the images suggest and what they cannot settle.
- 3
Clarification
We may ask about height, attachment, age, materials, and where movement occurs.
- 4
Site assessment
Structural questions and hidden conditions usually require an on-site review.
- 5
Written scope
You receive the recommended work, inclusions, exclusions, and conditions that could change it.
- 6
Scheduling
If you proceed, scheduling follows the confirmed scope and material availability.
Sending the request starts the assessment. It is not a diagnosis, quote, or booked appointment.
Deck repair questions
Answers about repairability, resurfacing, permits, matching, and safe next steps.
It depends on the frame. If the structure and footings are sound and damage is limited to the surface or components, repair may be the right answer. A moving or widely deteriorated frame can make replacement the better value. The assessment settles that decision.
Only after the frame has been assessed. New boards can hide a failing structure, and the frame must support the chosen surface material.
It may mean replacing boards while retaining the frame, refinishing the existing surface, or applying a coating. Those are different jobs with different costs and results. Our scope names the actual method.
Permit requirements depend on the work and municipality, especially when a repair changes the structure, size, height, or stair configuration. Toronto's decks and porches guide is the starting point if you are in the city.
New wood starts a different colour from weathered wood and takes time to catch up. Composite matching depends on whether the same product line and colour remain available. We explain the likely match before work starts.
Yes, where the surrounding structure can safely support the repair. A moving guard or stair may point to a frame problem, so the assessment looks beyond the component itself.
Stop using it and keep children and pets off it. Send photos and identify the safety concern clearly. Do not climb under or onto an unsafe deck to take pictures.
Finishing work is separate from structural repair. Include it in your request and we will assess the condition and appropriate scope.
Photograph the damaged area close up and from a distance, plus the stairs, each railing, the house connection, and the underside if you can reach it safely. Wide shots show the scale of the deck.
