Scope & size
How many rooms, how much square footage, and whether it is a refresh or a full gut.
Layout changes
Moving walls, plumbing or gas lines costs more than keeping the existing layout.
Structure
Load-bearing walls, beams, foundations and additions need engineering and permits.
Materials & finishes
Cabinets, counters, tile, flooring and fixtures range widely in price.

Home Renovations in Dunnville: Kitchens, Bathrooms, Basements and More
Century and heritage homes in Dunnville
Dunnville's older homes, many built before the Second World War, have character worth keeping and systems that usually are not: knob-and-tube or early wiring, plaster and lath walls, stone or block foundations, and framing that is rarely square. We open these houses carefully, test for asbestos and lead paint before demolition, and plan for what is behind the walls instead of pretending it will not be there.
Rural homes on well and septic in Dunnville
Rural properties around Dunnville bring their own considerations. Homes on a private septic system and well need the system checked before adding bedrooms, bathrooms or a second unit, because more bedrooms means more daily flow, and a septic system has to be sized for it. Larger lots give more room for additions and outdoor space.
Lakefront and riverside properties in Dunnville
Lakefront and riverside homes around Dunnville deal with higher water tables, wind, ice and moisture. Work near a shoreline, floodplain or valley often needs a permit from the conservation authority as well as the municipality, and materials and fasteners have to be chosen for wet conditions.
Kitchen Renovations in Dunnville
In Dunnville, homeowners from Downtown Dunnville and Port Maitland call us when the kitchen no longer fits the way they live. Some want an island and an open sightline to the family room, others want the same footprint with better cabinets, lighting and counters. Both are worth doing well.
We handle the whole Dunnville kitchen remodel as one project: demolition, any wall removal or structural work, plumbing and electrical by licensed trades, cabinets, counters, backsplash, flooring and paint, in the right order and on a written schedule.
Bathroom Renovations in Dunnville
Whether it is a main bath in Downtown Dunnville or a new basement bathroom anywhere in Dunnville, we plan the layout, the plumbing and the waterproofing first, then the finishes you will see every day.
Every Dunnville bathroom we build gets a continuous waterproofing membrane, a properly sloped shower base and an exhaust fan sized for the room, with plumbing by licensed trades and tile set flat and true.
Basement Finishing in Dunnville
Dunnville basements vary a lot, from older foundations that need careful moisture work to newer poured basements ready to finish. We plan each one around the house it is in.
Every Dunnville basement we finish starts with a moisture check, then proper foundation insulation, framing, electrical and plumbing, drywall, below-grade flooring and lighting, with egress windows wherever a bedroom is planned.
Legal Basement Apartments in Dunnville
Demand for legal basement apartments in Dunnville is strong, whether for rental income, a parent moving closer or a young adult who wants their own space. Many older town homes, lakeshore cottages and farm properties in Downtown Dunnville, Port Maitland and Byng have basements well suited to a secondary suite.
Secondary suites in Dunnville are approved by the Haldimand County, which sets its own zoning, parking and entrance rules on top of the Ontario Building Code and Fire Code. We check what your lot allows, coordinate drawings and the permit, then build the suite and book inspections through to final sign-off.
Home Additions in Dunnville
In Dunnville, an addition is often the answer for families who love their street in Downtown Dunnville and Port Maitland but have outgrown the house. With older town homes, lakeshore cottages and farm properties, rear additions, second storeys and main-floor suites are all common.
Accessible Renovations in Dunnville
Many Dunnville homeowners want to stay in the neighbourhood they know, in Downtown Dunnville, Port Maitland and Byng and beyond, and the right changes to the bathroom, entrances and main floor make that safer and easier.
Renovating in Brant, Haldimand & Norfolk
Along the Grand River and down to Lake Erie, small-town homes, farmhouses and newer subdivisions share the same needs: updated kitchens and bathrooms, finished basements, accessibility upgrades and solid outdoor space.
