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.

Frequently Asked Questions About Siding Installation & Repair in Markham
Siding installation in the GTA costs $5-$15 per square foot depending on material. Vinyl siding is the most affordable at $5-$8/sq ft, aluminum runs $7-$10/sq ft, and fiber cement (James Hardie) costs $10-$15/sq ft. A typical home costs $8,000-$22,000 fully installed. Contact RenoHouse for a free estimate.
Vinyl siding is the most popular for its affordability and low maintenance. Fiber cement (James Hardie) is the premium choice — it resists rot, fire, and insects, and lasts 50+ years. Aluminum is excellent for durability and fire resistance. The best choice depends on your budget and aesthetic preferences.
A typical home siding installation takes 1-2 weeks depending on house size, siding type, and weather conditions. RenoHouse works efficiently to minimize disruption while ensuring quality installation.
Yes, significantly. New siding with proper insulation board and house wrap improves your home's R-value, reducing heating and cooling costs. Insulated vinyl siding and fiber cement with foam backing provide the best energy performance for Markham's climate.
Replacing siding with the same material typically doesn't require a permit in Markham. However, if structural changes are involved, a permit may be needed. RenoHouse advises on requirements during your free estimate.
RenoHouse provides a workmanship warranty on all siding installations. Manufacturer warranties vary: vinyl siding typically carries a lifetime limited warranty, while James Hardie fiber cement offers a 30-year non-prorated warranty.
Yes, in many cases we can repair or replace individual damaged siding panels without a full replacement. We carry common siding profiles and can often match existing siding. RenoHouse assesses the damage during a free inspection.
RenoHouse installs siding from top manufacturers including James Hardie, KP Building Products, Gentek, Kaycan, and Royal Building Products. We help you choose the right brand and product for your home and budget.
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.
