Basement Renovation in Cambridge, Ontario
Cambridge is a city of three distinct characters — the historic brick streetscapes of Galt, the riverside charm of Preston, and the village energy of Hespeler. Whether your home is a century-old Grand River-side property or a newer build in Fiddlesticks or Blair, its basement holds real untapped potential. We transform underused lower levels into polished, liveable spaces built for how your family actually lives — home offices, rental suites, rec rooms, and more.

Frequently Asked Questions About Cambridge Basement Renovations
Answers to the questions Cambridge homeowners ask us most before starting their renovation.
For most Cambridge homes, basement renovation projects range from $35,000 to $80,000+, with the final cost depending on square footage, layout complexity, and your choice of finishes. A basic open-concept finish typically starts around $25,000, while a fully equipped space with a bathroom, kitchenette, and separate entrance can exceed $100,000. Older Galt-area homes may require additional foundation or moisture work that affects the overall budget. We provide a free, detailed estimate for every project before any work begins.
A typical basement finishing project in Cambridge takes 6–10 weeks once work gets underway. Projects that include a bathroom addition, separate entrance, or legal secondary suite may require 12–16 weeks to complete properly. During your free consultation, we'll map out a realistic schedule so you always know what to expect and when.
Yes — in Cambridge, a building permit is required for most basement renovation work, including framing new walls, adding or altering electrical and plumbing, installing egress windows, and any change to the HVAC system. The City of Cambridge's Building Division oversees approvals, and permit applications for basement apartments typically take about 3 weeks to review. We handle the entire permit application and inspection process on your behalf.
Absolutely. We build fully legal secondary suites and basement apartments that comply with Cambridge's Zoning By-law 108-18 and Ontario's building code. Every detail is covered — separate entrances, full kitchen installations, fire-rated wall assemblies, egress windows, and all required safety features — so your suite is both legal and ready to generate rental income. Note that Cambridge permits a maximum of 2 bedrooms in a basement apartment.
Moisture management is the foundation of every project we take on — especially in Cambridge where many older homes in Galt and Preston sit close to the Grand River. Before any framing begins, we conduct a thorough moisture and foundation assessment. We then install the appropriate combination of vapour barriers, drainage membranes, and sump pump systems, and select mould-resistant materials throughout. The result is a finished basement that stays dry and healthy for the long term.
Your basement can become practically anything. Cambridge homeowners commonly choose home theatres, private gyms, home offices, kids' playrooms, guest bedrooms, wet bars, wine rooms, rental suites, or a combination of uses. We design the layout around your lifestyle so every square foot is working for you.

Trusted by Cambridge Homeowners
"We have a 1940s semi-detached in Galt and were nervous about what the foundation would look like underneath. The Peace of Mind Interiors team did a thorough moisture assessment upfront and addressed everything before starting. The finished basement is now our favourite room in the house — a proper home office and a guest suite combined. Couldn't be more pleased."
"We moved to Hespeler two years ago and finally pulled the trigger on finishing our basement. Peace of Mind handled everything from the 3D design right through to the final inspection. The crew was professional, tidy, and always on schedule. We now have a kids' playroom and a home gym downstairs — the family loves it. Highly recommend to anyone in the Cambridge area."
"We wanted a legal basement apartment in our Fiddlesticks home to help offset the mortgage. Peace of Mind Interiors walked us through the permit process, explained the Cambridge by-law requirements, and built exactly what we needed — a bright, fully self-contained one-bedroom suite. It was rented within a week of completion. Absolutely worth every penny."
