Markham's suburban properties are perfect for outdoor living upgrades — composite decks in Angus Glen, cedar fences in Cornell, and professional gutter systems in Raymerville. We handle City of Markham permits and build outdoor structures that meet Ontario code while maximizing enjoyment of your yard.
Mature tree coverage in established Markham neighborhoods like Unionville and Thornhill-Markham makes gutter maintenance and leaf guard installation essential. We install seamless aluminum gutter systems with leaf guards to keep Markham homes protected from water damage year-round.
Newer suburban homes benefit from deck construction, fence installation, and landscape hardscaping that builders typically don't include. These additions create functional outdoor living spaces and increase property value — composite decking and vinyl fencing are popular choices for their durability and low maintenance requirements.
Average deck building & construction cost in Markham and the GTA: $2000–$15000 per project, depending on scope — deck staining starts around $2,000, while full deck builds and siding replacement run $8,000–$15,000+.

Frequently Asked Questions About Deck Building & Construction in Markham
Deck costs in the GTA vary based on size, materials, and design. A basic 10x12 pressure-treated deck starts around $3,000-$5,000. Cedar decks cost $5,000-$10,000+, and composite decks range from $8,000-$20,000+ depending on size and features.
In most Markham municipalities, decks over 24 inches above grade require a building permit. RenoHouse handles the permit application process as part of our deck building service.
Pressure-treated lumber is the most affordable, cedar offers natural beauty and rot resistance, and composite is low-maintenance and long-lasting. Each has pros and cons — RenoHouse will help you choose based on your budget and preferences.
A standard deck takes 3-7 days to build depending on size, complexity, and weather. Multi-level decks with features like pergolas or built-in seating may take 1-2 weeks. RenoHouse provides a timeline during your consultation.
Composite decking offers the best weather resistance and lowest maintenance for Markham's freeze-thaw climate. Pressure-treated lumber is the most affordable option. Cedar offers natural beauty but needs regular maintenance.
Yes, RenoHouse provides a structural warranty on all deck construction. Composite decking manufacturers typically offer 25-50 year product warranties. We build to code and stand behind our work.
While possible for handy homeowners, deck building requires knowledge of structural engineering, building codes, and permit processes. Professional construction by RenoHouse ensures safety, code compliance, and lasting quality.
Yes, RenoHouse builds decks across Markham, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, and all surrounding communities.
New pressure-treated wood decks should weather for 3–6 months before staining to allow the wood to dry and accept stain properly. After that, we recommend semi-transparent stain for a natural look or solid stain for maximum UV and weather protection. Re-staining every 2–3 years keeps your deck looking great.
Vinyl and composite fences are the most popular for newer suburban homes — they require zero maintenance, won't rot or warp, and come in styles that complement modern architecture. Cedar is the premium wood choice, offering natural beauty with proper annual maintenance. We help you choose based on budget, privacy, and aesthetic preferences.
In Ontario, decks higher than 24 inches (60 cm) above grade or attached to the house typically require a building permit. Most suburban backyard decks fall into this category. We handle the permit application process and ensure your deck meets current Ontario Building Code requirements for structural integrity and safety.
