Valcast Construction handles the complete basement finishing process from start to finish, so you’re not juggling four different contractors.

We bring together framing, insulation, drywall, flooring, trim carpentry, and painting under one roof — delivering a turnkey finished basement on time and within your budget, anywhere in Toronto and the Greater Toronto Area.

Frequently Asked Questions Regarding Basement Flooding and Restoration

Q: Do I need a permit to finish my basement in Toronto?

A: In most cases, yes — if you're adding walls, bedrooms, or a secondary suite, a building permit is required. We'll help you understand what's needed for your specific project and can coordinate with the city on your behalf.

Q: How long does a basement finishing project take?

A: A typical basement of 600–900 sq ft takes 3–5 weeks depending on scope. We'll give you a realistic timeline before work starts.

Q: What type of insulation do you use in basements?

A: We recommend closed-cell spray foam on foundation walls for moisture and thermal performance, combined with acoustic batt insulation in interior partition walls for sound control.

Q: Can you build a legal basement apartment or secondary suite?

A: We handle all the interior finishing work required for a secondary suite — including fire-rated assemblies, egress framing, and soundproofing. You'll need a separate electrician and plumber, but we coordinate closely with those trades.

Q: Do you handle flooding restoration before finishing?

A: Yes — we offer basement flooding restoration services. If your basement has had water damage, we can remediate and then finish it. See our Flooding Restoration page for details.
