Markham's blend of heritage homes in Unionville and contemporary builds in Cornell requires a contractor who's versatile. RenoHouse handles both with equal skill.
RenoHouse is the name Markham homeowners trust for quality work. Markham homeowners — experience the RenoHouse difference.
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 composite deck installation 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 Composite Deck Installation in Markham
Composite decks offer superior durability, require virtually no maintenance (no staining, sealing, or painting), resist rot, insects, and fading, and come with long warranties.
In Markham, composite deck installation typically ranges from $45-75 per square foot, including the frame. Most projects fall between $8,500 and $38,000, with an average around $18,000.
We specialize in installing premium composite decking from leading brands like Trex Transcend, TimberTech Azek, and Fiberon, known for their quality and longevity.
Yes, most deck installations in the GTA require a building permit. We can guide you through the permit application process to ensure your project complies with all local regulations.
The timeline varies based on deck size and complexity, but most standard composite deck installations are completed within 1-3 weeks from start to finish, once permits are secured.
We use robust concrete sonotube footings to ensure a stable and long-lasting foundation for your composite deck, designed to withstand Markham's climate.
While not entirely "maintenance-free," composite decks require significantly less upkeep than wood. Occasional cleaning with soap and water is usually all that's needed to keep them looking great.
We proudly serve Markham and the entire Greater Markham Area (GTA), including Etobicoke, Scarborough, North York, Vaughan, Mississauga, Brampton, and 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.
