Know the Risks First
Mississauga Home Renovation Problems We Fix Up Front
The local problem
A basement apartment you cannot register or rent with confidence
What you seeThere is a kitchen and bedroom downstairs but no permit on file, so insurance, a future sale and the tenancy all rest on a unit the City has never inspected.
Why it happens hereSecond units here are registered under By-law 114-16, and any suite built after July 14, 1994 needs a building permit before it can be registered. That covers most suites added to the area's 1970s-2000s homes.
How we fix itOur basement renovation team brings the suite to code with egress, fire separation and alarms, files the permit (fees are refunded for additional units) and guides the registration.
Budget killer 1
Permit + Committee of Adjustment delays
6-16 weeks of approvals and $8K-$40K in consultant fees when design ignores zoning, heritage and conservation rules.
Budget killer 2
Hidden conditions behind old walls
Knob-and-tube wiring, asbestos, 60-amp service, lead solder and rot found after demolition with no agreed pricing.
Budget killer 3
Material scope creep
Unrealistic allowances for tile, fixtures and flooring that double mid-build.
The Whole House Renovation Fix
In-house permit coordination, a 5-8% discovery contingency on Tier 2+ contracts, and materials allowances locked in writing with a signed change-order protocol.
Before You Start
What to Plan For Before You Renovate
Mississauga renovation work splits two ways. In Erin Mills, Meadowvale and Churchill Meadows, owners of 5 to 15-year-old builder-grade homes want better kitchens, baths and a basement that earns its keep. In Mineola, Lorne Park and Port Credit, owners on large lots are planning additions or full luxury rebuilds. Both need the same thing from a contractor: a fixed price before design, a realistic timeline and someone who knows the City of Mississauga permit process.
Heritage + older homes
Older Port Credit and Streetsville homes with original systems.
Heritage restorationInfill, additions + upgrades
Builder-grade upgrades in Erin Mills and Churchill Meadows; luxury infill and rebuilds in Mineola and Lorne Park.

What Our Clients Say
Names are shown as initials and neighbourhood to protect client privacy.
"Registered second-unit suite with a written warranty. Rental income started month 5. Inspection passed first visit."
"Our 1940s kitchen had a wall in exactly the wrong place. They brought in the engineer, put in a beam and moved the sink to a new island without opening the dining room ceiling twice. The written scope listed every allowance, so we knew where all $96K was going. Done in nine weeks."
"Small job for them, big deal for us. New tile, vanity and fixtures in our ensuite and powder room for $24K, finished in five weeks, and the crew cleaned up every single day."
Local Knowledge
Local Renovation Experience in Mississauga
How We Deliver From the Lakeshore to Meadowvale
We reach projects along the QEW, the 403 and Highway 401, with most sites in Erin Mills, Meadowvale and Churchill Meadows reached from Erin Mills Parkway, Winston Churchill Boulevard and Mississauga Road. Lakeshore work in Mineola, Lorne Park and Port Credit comes off Hurontario Street and Lakeshore Road.
Permits are filed with the City of Mississauga Building Division. Second units need a building permit and inspections, and the City has its own second unit registration step once the suite passes. We guide you through both so the unit can be rented legally.
In Mineola and Lorne Park, large lots and mature trees mean infill and additions can need site plan or tree permit review. We confirm the requirements during feasibility, before you spend money on full drawings.
The Homes We Upgrade
Erin Mills, Meadowvale and Churchill Meadows are dominated by 1990s-2010s builder-grade two-storey homes: thermofoil cabinets, laminate counters, builder tubs and unfinished or half-finished basements with 8 foot pours. Those homes respond well to Tier 1 and Tier 2 work: a full kitchen to the studs, a primary ensuite with a curbless shower and a legal basement suite with egress windows.
Mineola and Lorne Park bring 1950s-60s bungalows and ranches on deep treed lots, where the conversation turns to large rear additions, custom rebuilds and luxury finishes like rift white oak, Calacatta and Wolf/Sub-Zero packages. Port Credit and Streetsville add older village homes with original wiring and plumbing that need a careful whole-house approach.

Got Questions?
Mississauga Renovation Questions Answered
Can you build a legal basement suite in Erin Mills?
Yes. Our Erin Mills suite cost $62K, passed inspection on the first visit and started earning rent in month 5. It included egress windows, fire separation, smoke and CO alarms and a separate entrance, all built to OBC second-unit requirements.
Do Mississauga second units need to be registered?
Yes. Second units are registered under By-law 114-16. Registration is free, but any unit built after July 14, 1994 needs a building permit first, and the City refunds permit fees for additional units. We handle drawings, the permit and the inspection the registration relies on.
Do you do luxury infill builds in Mineola and Lorne Park?
Yes, custom rebuilds and large additions, typically $400K-$1.2M+ for custom homes. Both are Neighbourhood Character Areas in the Official Plan, so we review the area policies, tree and grading requirements early so approvals do not hold up construction.
Can you upgrade a 10-year-old builder-grade home?
Yes. Kitchen, bath and basement refreshes are common in Churchill Meadows and Meadowvale, with fixed pricing up front. Kitchens typically run $35K-$140K, primary baths $18K-$65K and basements $45K-$180K.
How long does a Mississauga basement take?
Around 8 weeks for a suite like Erin Mills; longer with underpinning. Permit time is planned into the schedule before work starts, so the date you see at signing is realistic.
