Home Renovation in Mississauga
Complete interior transformations from the studs out.
A home renovation in Mississauga most often means reworking a house from one of three eras: a village-core home in Port Credit or Streetsville, a post-war bungalow or split-level, or a 1970s–80s two-storey in Meadowvale or Erin Mills. Each hides different problems, so we scope a full home renovation from the structure and services outward before anyone picks a finish.
Nexon Build delivers whole-house renovations as one fixed-price contract, with demolition, structural work, plumbing, electrical and HVAC rough-ins, insulation, drywall and custom millwork run by a single renovation contractor team. We file drawings through the City's ePlans portal, coordinate tree and heritage approvals where they apply, and track schedule, selections and change orders in Buildertrend.

What Mississauga Houses Reveal Once the Walls Open
In the post-war belt around Applewood, Cooksville and Clarkson, opening walls typically exposes electrical panels sized for a smaller household, corroding galvanized pipe, original cast-iron stacks and little wall insulation. Bungalow interior walls often carry ceiling joists, so open plans need engineered beams. The usual order of work is laid out in our post-war bungalow renovation guide.
Meadowvale and Erin Mills houses from the 1970s and 1980s need layout work more than rescue: removing the wall between kitchen and family room, rebuilding stairs and bathrooms, replacing original windows and turning the basement into living space. Village-core homes call for the opposite order: survey the structure first, then design around what it can carry.
Permits for a Whole-House Renovation in Mississauga
Cabinetry, painting and same-spot fixture swaps don't need a permit, but a full home renovation almost always crosses the line. The City requires one whenever structure changes, a window or door opening is added or widened, a plumbing fixture is added or moved, ductwork is altered or a basement is finished. Applications go in through ePlans with an Applicable Law Form, and each resubmission can add two or more weeks, so complete drawings matter. Submission requirements are explained in our Mississauga permit requirements guide.
Two approvals sit outside the building permit. If excavation, scaffolding or a new rear door could injure a private tree 15 cm or larger, a tree permit comes first. Inside Mississauga's three heritage conservation districts, exterior changes may need heritage approval, so we confirm status before design. Our Mississauga renovation guide maps every overlay.
Full Home Reno Budgets in Lorne Park and Meadowvale
A mid-level refresh of a Mississauga house starts around $150K, a full gut with standard finishes runs $450K and up, and premium work passes $800K, or roughly $200–$450 per square foot for a full gut. Larger Lorne Park houses drift upward because there is simply more to rebuild. The line-by-line picture is in our GTA renovation cost breakdown.
If the scope reaches the foundation, compare renovation against an addition or a rebuild before committing. A bungalow on a wide RL lot may gain more from a second storey, covered on our home addition Mississauga page, than from a gut alone. Putting both paths on paper lets you choose on numbers rather than instinct.

Common questions
Does a home renovation in Old Port Credit Village need heritage approval?+
It can. All properties within the Old Port Credit Village Heritage Conservation District are designated under the Ontario Heritage Act, and the district plan in force since January 2020 guides change there. Before design is fixed, we confirm with the City's heritage planners which parts of your scope need a heritage permit.
Which Mississauga renovations trigger a private tree permit?+
Any work that would injure or remove a private tree 15 cm (6 inches) or more in diameter, including a dead or dying one. Typical triggers are new footings, a rear walkout, service trenches or machinery over the root zone. Each removal generally requires one replacement tree per 15 cm of diameter.
Can I add a basement unit during a whole-house renovation in Mississauga?+
Yes, and combining them is efficient, since walls, plumbing and HVAC are already open. The unit needs its own permit scope, a below-grade entrance at the back or along an interior side yard, and registration as a second unit once inspections pass. The City also refunds the building permit fees on an ARU after its final inspections.
