What is the best way to insulate an old house?

That's a great project question! For specific renovation advice like insulation types, R-values, and installation methods, check out resources focused on energy efficiency and home improvement. Here at OCN, we focus on helping you find and work with the right contractor for your insulation project.

When hiring an insulation contractor in Ottawa, here's what you need to know about the process:

Permits and Code Requirements
Most insulation work in Ottawa doesn't require a building permit unless you're opening walls or changing structural elements. However, if you're adding insulation during a renovation that involves electrical or plumbing work, you'll need permits through the City of Ottawa Building Code Services (613-580-2424). Any electrical work to accommodate new insulation absolutely requires an ESA permit.

Finding Qualified Insulation Contractors
Look for contractors with WSIB clearance certificates and proper liability insurance. In Ottawa, many insulation contractors also handle air sealing and energy audits. Verify their WSIB status at wsib.ca/clearances - this protects you if someone gets injured on your property.

Getting Multiple Quotes
Insulation quotes should specify the type of insulation, R-values, square footage, and whether they're including vapor barriers or air sealing. In Ottawa's climate, proper air sealing is crucial alongside insulation. Get at least three detailed written quotes and be wary of door-to-door salespeople or high-pressure tactics.

Red Flags to Watch For
Avoid contractors who demand full payment upfront, lack proper insurance, or can't provide local references. Be especially cautious of companies offering "free" energy audits that turn into high-pressure sales presentations. Legitimate energy audits in Ottawa typically cost $300-600.

Energy Rebates and Inspections
Many Ottawa homeowners qualify for federal and provincial energy rebates. These require before-and-after energy evaluations by certified energy advisors. Make sure your contractor understands these requirements if you're pursuing rebates.

Payment and Protection
For major insulation projects over $50,000, Ontario's Construction Lien Act requires you to hold back 10% of payments for 60 days after completion. This protects you if there are issues with materials or workmanship.
