Deck Building
Custom deck construction in London, Ontario
Building a new deck in London Ontario starts with picking the right material for your budget and how much upkeep you want to deal with. We handle everything from permits and footings to the framing, railings, stairs and any built-in features. You show us the space and we build something that fits it properly.
Material Options
Pressure Treated (PT)
Most affordable. Lasts 15 to 20 years. Rot and insect resistant.
Cedar
Naturally rot resistant. Weathers beautifully and takes stain well.
Composite (Trex / TimberTech)
Never needs staining. Lasts 25 to 30 years with almost no upkeep.
PVC
Fully waterproof. Top tier performance and longevity.
What Is Included
Permits and Planning
We pull permits and work through the layout and footing plan with you first.
Full Build
Frame, decking, stairs, railings, and built-ins all included in the quote.

Deck Restoration
Deck staining, repair, and new builds in London, Ontario
A quality deck restoration in London Ontario starts before the stain ever goes on. We pressure wash to strip out the dirt, mildew and old failing stain. Then we sand the surface smooth so the new finish actually bonds to the wood instead of peeling off in a season. Any rotten or split planks get replaced. Loose railings and balusters get tightened or swapped out. Then two coats of premium stain or sealant go on top. The result looks new and stays protected for the next 2 to 3 years. We also build decks from scratch — PT, cedar, composite or PVC, full permits and footings included.
Restoration Process
Pressure Wash
Strips dirt, mildew and old failing stain from every plank.
Sand
Smooths the surface so the new finish bonds properly and lasts.
Repair
Rotten planks replaced. Loose railings and balusters tightened or swapped.
Two Coat Finish
Premium stain or sealant in solid, semi-transparent or clear finish.
We Also Build Decks
PT, Cedar, Composite, PVC
We help you pick the right material for your budget and maintenance preference.
Full Build Included
Permits, footings, framing, railings, stairs — everything in one quote.

Interlock
Interlock releveling and polymeric sand in London, Ontario
If your interlock patio or driveway has sunken pavers, wide joints full of weeds, or sections that no longer drain properly, we can fix it without replacing the whole surface. We do full releveling jobs — lifting and resetting every paver on a fresh compacted base — and we also do polymeric sand top-ups where the structure is solid but the joints have filled with weeds. Either way the result is flat, weed-free and locked in properly.
What We Offer
Full Releveling
Every sunken or shifted paver lifted, base re-compacted, and pavers reset to a flat even finish.
Polymeric Sand Top-Up
Joints cleaned out and packed with fresh polymeric sand — locked with water to kill weeds for years.
Pressure Wash and Clean
Surface washed before and after so the finished job looks sharp.
No Full Replacement Needed
Most interlock problems are fixable without pulling everything up. We tell you honestly which approach fits.

Siding Wash
Exterior soft wash in London, Ontario
Soft washing siding in London Ontario is not the same as blasting it with a pressure washer.

The whole house looks 10 years newer and the job usually takes half a day.
Works On
Vinyl Siding
Low pressure soft wash removes algae and mildew without warping the panels.
Aluminum Siding
Matched detergent lifts oxidation and surface grime without scratching.
Brick
Removes moss, efflorescence and staining from mortar and brick face.

Exterior Painting
Exterior painting to keep your property looking its best in London, Ontario
A fresh coat of exterior paint is one of the best things you can do to keep your property looking clean and well-maintained. We pressure wash, scrape failing paint, sand rough areas, prime bare wood and caulk all the gaps before anything goes on. Then two coats minimum of Sherwin-Williams or Benjamin Moore — premium paint only, because builder-grade product does not hold up through Ontario winters. Properly done exterior painting protects wood from rot, moisture and UV damage and keeps your curb appeal sharp for years.
What We Paint

Clean sharp lines on every edge with proper prep so it does not peel.
Doors
Front doors, garage doors and any exterior door refreshed and protected.

Roof Cleaning
Soft wash roof cleaning in London, Ontario
Those black streaks and green patches on roofs in London Ontario are algae, moss and lichen feeding on the shingles. Left alone they trap moisture and shorten the life of the roof significantly.

The treatment is safe for asphalt, cedar shake and metal roofing and does not void manufacturer warranties. Our crew is Working at Heights certified so the job is done safely every time.
What We Do
Soft Wash Method
Low pressure treatment removes algae and moss without damaging shingles or voiding warranties.
Black Streak Removal
Gloeocapsa magma algae removed completely, not just rinsed off the surface.
Moss and Lichen
Growth killed at the root so it does not come back within the season.
