Our Process for Mississauga Renovations

Site Visit & Discovery

We come to your Mississauga home, take measurements, look at the existing structure, ask questions, and listen to what you want — not what's easiest to sell. This visit is always free and there is no obligation.

Written Quote with Real Numbers

You get a detailed quote within about one week. Materials, labour, timeline, payment schedule — all spelled out so you know exactly what you're agreeing to.

Permits with the City of Mississauga

Mississauga's permit process is more involved then some neighbouring cities, especially in heritage areas or near the lake. Our team handles all permits, drawings, and inspections directly with the City of Mississauga.
