Insulation in Markham

RenoHouse installs spray foam insulation, blown-in cellulose and fiberglass, and fiberglass batt insulation. We recommend the best type based on the area being insulated, your budget, and the R-value required for Ontario climate performance.

Insulation costs depend on the type, area size, and accessibility. Blown-in attic insulation typically ranges from $1.50 to $2.50 per square foot, while spray foam insulation ranges from $3 to $7 per square foot. RenoHouse provides free on-site estimates with transparent pricing.

Ontario Building Code requires R-50 for attics and R-24 for exterior walls in new construction. For existing homes, upgrading to these levels provides the best energy savings. RenoHouse assesses your current insulation and recommends the optimal upgrade.

Spray foam provides the highest R-value per inch, creates an air-tight seal, and acts as a vapor barrier. While more expensive upfront than blown-in or batt insulation, it delivers superior energy savings and typically pays for itself within 3 to 5 years through lower heating and cooling bills.

In some cases, yes. Blown-in insulation can be injected through small holes into enclosed wall cavities. For unfinished basement walls, we can install spray foam or rigid foam board directly. RenoHouse assesses the best approach during the free estimate.

Yes, RenoHouse provides all necessary documentation for rebate programs including the Canada Greener Homes Grant, which can cover up to $5,000 of insulation upgrade costs. We walk you through the application process and ensure your project qualifies.

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.
