1. Do you handle permits and inspections in Ottawa?

We advise on code requirements and can assist with what to put on your permits. For complex projects, we coordinate with local inspectors and contractors.

2. How long does a typical job take?

Small basement sections can be done in a day; most full-basement projects take 1–2 days depending on size and scope. Spray-foam requires homeowners and pets to be out of the premises for 24-48 hours after installation – so we calculate this into the time when creating estimates

3. Do you offer warranties

Yes. We provide workmanship warranties and help with manufacturer warranties where applicable.

4. Should I insulate my concrete basement walls?

Yes, insulating concrete basement walls is essential to improve energy efficiency, prevent moisture and mold growth, and enhance overall comfort. Spray foam insulation is particularly effective for concrete walls due to its ability to create an airtight seal and provide excellent thermal insulation.

5. Can you insulate a finished basement without major demolition?

In many cases, yes. We’ll evaluate and recommend the least-invasive method that meets safety and code requirements.

6. What are the basement insulation requirements in Ontario?

In Ontario, basement insulation requirements are governed by the building code, which specifies minimum R-values for different types of insulation. For example, spray foam insulation may have different requirements compared to fiberglass or cellulose. At Spray-Tech Insulation, we ensure all installations meet or exceed these requirements.
