London Deck Builder
London Deck Builder constructs pressure-treated, cedar, composite and PVC decks for homeowners across London and Southwestern Ontario. The company backs its work with a 5-year workmanship warranty and is known for permit assistance alongside the build itself.
Strengths
- Builds in four common decking materials, from budget pressure-treated wood to low-maintenance composite and PVC.
- Includes permit assistance, which removes a common friction point in Ontario deck projects.
- Backs new builds with a 5-year workmanship warranty.
- Handles deck repair and maintenance, not just new construction, useful for extending an existing deck's life.
- Reviews specifically mention successful blending of new construction onto an existing deck, a harder job than a fresh build.
Considerations
- Best suited to full deck builds or additions rather than very small repair jobs; ask if minimum project size applies.
- Composite and PVC decking cost more upfront than pressure-treated wood, so budget-focused homeowners should ask for a like-for-like comparison.
- Permit timelines are set by the municipality, not the builder, so expect the permit step to add lead time before construction starts.
- Not a fit if you need fencing or retaining wall work in the same visit; this business is deck-focused.
- Very small repair or single-board fixes may fall below the company's typical project scope, so ask before booking.
Best for
- Homeowners planning a new deck build in pressure-treated wood, cedar, composite or PVC
- Anyone extending or blending new construction onto an existing deck
- Homeowners who want permit handling included rather than managed separately
- Properties needing deck lighting, added features, or repair to an aging deck
What they do
London Deck Builder builds decks in pressure-treated wood, cedar, composite and PVC, plus deck lighting and features, and offers repair and maintenance on existing decks. That range means a homeowner can go from a first consultation through material choice, permit application, and eventual upkeep with the same company.
How they work
The company includes deck permit assistance as a named service, which matters in Ontario since most raised decks require a building permit from the local municipality. It backs new builds with a 5-year workmanship warranty and is described as transparent on pricing, which homeowners should confirm covers materials and labour separately.
What homeowners say
One review describes a project where the builder doubled the size of an existing deck and blended new construction seamlessly with the old, a harder technical job than building from scratch. A second reviewer highlighted the planning stage specifically, saying the team's input shaped a design that was both practical and visually finished.
