Basement Finishing in Peterborough
In Peterborough, a finished basement is one of the most requested projects we quote, especially in older brick homes, established neighbourhoods and newer subdivisions. Families in Downtown, East City and Ashburnham use that space for a rec room, an office, a gym or a guest suite instead of moving to get more room.
We finish Peterborough basements from bare concrete to move-in ready: insulation, framing, bathrooms, wet bars, laundry, pot lights, drywall, flooring and trim, with the permit and inspections handled.
Building permits for basement finishing in Peterborough are issued by the City of Peterborough. We tell you up front whether your project needs one, prepare or coordinate the drawings, and book the inspections so the work is signed off properly.
Call (647) 424-1511 or send the form on this page for a free basement finishing quote in Peterborough. Tell us what you want to change, add a few photos of the space, and we will book a visit and send a written quote that lists the scope, the materials, the permits involved and the schedule.
Peterborough homes
What basement finishing involves in Peterborough's houses
Century and heritage homes in Peterborough
Basements in Peterborough's older homes often have stone, rubble or block foundations and low ceilings. They can be finished, but insulation has to suit the foundation so moisture is not trapped, and gaining height means underpinning or a bench footing, designed by an engineer and covered by a permit.
Post-war bungalows and back-splits in Peterborough
Post-war Peterborough bungalow basements are usually a single open space with the furnace in the middle and a side door at grade. They finish well, but ceilings are often low, so bulkheads around ductwork are planned carefully, and old clay weeping tile and foundation cracks are checked before anything is framed.
1970s to 1990s family homes in Peterborough
Many Peterborough basements from the 1970s to the 1990s were finished decades ago with wood panelling, drop ceilings and carpet on the slab. We usually take them back to the foundation, check for moisture, insulate properly and rebuild with a layout that suits how the family uses the space now.
Rules in Peterborough
Permits and approvals for basement finishing in Peterborough
Building permits
Building permits in Peterborough are issued by the City of Peterborough. Electrical work anywhere in Ontario is done by a licensed electrical contractor under an Electrical Safety Authority (ESA) permit. We confirm what your project needs before you sign and book every inspection.
Testing before demolition
Homes built before the 1990s can contain asbestos in plaster, textured ceilings, floor tile, vermiculite insulation and pipe wrap, and homes from before the 1960s often have lead paint. In Peterborough's older houses we test suspect materials before demolition and handle them by the regulations if they are found.
The service
Basements Finished Warm, Dry and Bright
A finished basement is often the most affordable way to add real living space to a home: a family room, a home office, a gym, a guest suite or a playroom. The difference between a basement that feels like part of the house and one that feels like a basement comes down to moisture control, insulation, lighting and ceiling height.
Before framing, we look for signs of water and fix the cause first. Then we insulate the foundation walls properly, frame, run electrical and plumbing, add pot lights, and finish with drywall, flooring suited to below-grade spaces, trim and paint. Many basements also get a bathroom, a wet bar or a laundry room.

Questions
Basement Finishing in Peterborough: FAQs
How do I get a basement finishing quote in Peterborough?+
Call (647) 424-1511, use the form on this page or email info@ontariorenovationcompany.com. Tell us what you want to change and send a few photos, and we will book a visit and send a written quote for your Peterborough project.
What kinds of Peterborough homes do you work on?+
All of them. Housing in Peterborough includes century and heritage homes, post-war bungalows and back-splits and 1970s to 1990s family homes, and each comes with its own considerations, from older wiring and foundations to builder warranties, septic systems and shoreline rules. We plan the work around the house you actually have.
Do I need a permit to finish my basement?+
In most Ontario municipalities, yes, particularly for new walls, bathrooms and bedrooms. A permit also protects you when you sell. We confirm the requirements and handle the application.
What if my basement has had water in it?+
We find and fix the cause first, whether that is grading, downspouts, a crack in the foundation or a plumbing issue. Finishing over an unresolved water problem just hides it.
Can you add a bedroom in the basement?+
Yes, as long as it has an egress window or exit that meets the Building Code, plus proper smoke and carbon monoxide alarms. We can enlarge an existing window opening if needed.
What flooring works best in a basement?+
Luxury vinyl plank is the most popular choice because it handles moisture and feels warmer underfoot than tile. We check the slab for moisture before recommending a product.
Do you offer basement finishing across Peterborough?+
Yes. We work throughout Peterborough, including Downtown, East City, Ashburnham, Westmount, Kawartha Heights, Northcrest and Otonabee, and in nearby Lindsay, Port Hope, Cobourg, Newcastle and Bowmanville.
