No entrance,
no suite

A legal secondary suite starts at the door: tenants need their own private, code-compliant way in. Cutting a foundation is serious structural work involving engineering, excavation, drainage and waterproofing.

We handle side entrances end to end: engineered concrete cutting, excavation and stairs, frost-protected footings, drainage that keeps water out for decades, and a finished entrance that looks like it was always part of the house.

  • Engineered concrete cutting
  • Proper drainage and waterproofing
  • Frost-protected stairs and landings
  • Code-compliant doors and lighting

Good to Know

Frequently asked questions

Don't see yours? Call us, we're happy to help.

Do I need a permit for a side entrance in Calgary?

Yes. Cutting a foundation requires engineering and City of Calgary permits. Both are included and managed by us.

How long does a side entrance take?

Typically 2 to 3 weeks including excavation, cutting, stairs, drainage and finishing, weather depending.

Will the stairwell flood or fill with snow?

Not built our way: proper drainage to weeping tile, frost-protected construction and optional covered entries handle Calgary weather.

Can a walkout replace a side entrance?

On sloped lots, yes. Walkout entrances at grade are ideal; we have built many across Calgary and Chestermere.
