Basement Finishing

Turn an unfinished basement into a warm, dry, code-compliant living space: family rooms, bedrooms, bathrooms and more.

A finished basement adds usable space without changing your home's footprint, but basements need extra care: moisture, ceiling heights, egress windows, fire separation and mechanical access all affect how the space is built.

ControBuild assesses your basement before quoting, identifies problems like moisture or low headroom early, and builds the space so it stays comfortable and compliant for years.

What's included

Framing, insulation and subfloor systems

Frequently asked questions

Do I need a permit to finish my basement?

In most cases, yes, especially if you are adding bathrooms, bedrooms, or altering electrical and plumbing. We help you determine what is required.

What if my basement has moisture problems?

Moisture should be solved before finishing. We assess it during the site visit and recommend the right approach before building anything.

Can you add a separate entrance or secondary suite?

That involves zoning, fire separation and permit requirements. We can discuss feasibility with you and coordinate the relevant approvals.
