Get More From the Home You Already Have
Most homes have more space than they use. There's the basement that's only storage, the main floor chopped into small rooms, and the bedroom that hasn't worked since the kids were little. Sometimes the problem goes deeper: a floor that sags or a wall that's cracking.
An interior renovation turns that space into rooms you actually live in, and fixes what's wrong underneath so it stays fixed.
SRL Contracting handles interior renovations across Thunder Bay, from finished basements to full structural changes. We work with a structural engineer when the job calls for it, handle the permits, and handle every trade from start to finish.

QUESTIONS
Basement & Interior Renovation FAQs
It depends on size, whether you add a bathroom or bedroom, and finishes. Moisture or structural issues found during the assessment are priced separately and upfront.
Most can, including load-bearing walls. A load-bearing wall needs a properly sized beam and posts carrying the load down to the foundation. Our structural engineer designs that, and we build it with temporary shoring in place.
It depends on the span, what's above, and whether plumbing, ductwork or wiring runs through the wall. After the site visit, we give you a detailed quote that includes engineering and the permit.
Not always, but it's worth checking. Sagging can come from undersized joists, a failing beam or post, or foundation movement. We assess the cause and recommend the right fix, with an engineer where needed.
Yes. A secondary unit needs a building permit and has to meet Building and Fire Code requirements for separation, exits and ceiling height. We handle the design, permit and construction.
Usually, yes. We seal off work areas, protect floors and clean up daily. For larger structural work, we'll tell you upfront if any part of the house will be unusable for a few days.
