Trusted construction & renovation experts serving the GTA and Ontario. From concept to completion, we build with precision and deliver with pride.
When you choose Proventa Construction, a general contractor in Mississauga, one team handles design, permits and construction. As a result, homeowners and real estate investors get clear pricing, a firm schedule and one point of contact.
Renovating in Mississauga takes more than good tools, because many homes date from the 1960s to the 1990s and carry dated layouts. For example, a bungalow in Cooksville, a two-storey in Erin Mills and a condo near City Centre raise very different challenges. Therefore, Proventa Construction Inc. plans each project around the property, not around a template.
Coordinating separate designers, trades and plan examiners often becomes a headache, but we remove it. Instead, our team manages every phase, from architectural concept drawings to the final coat of paint. As a result, you get consistent craftsmanship, a clear timeline and one point of contact. Before you decide, browse our recent projects or learn more about our company.
First, we prepare custom 2D and 3D concepts, structural drawings and zoning reviews. Then we handle City of Mississauga permit applications and Committee of Adjustment variance requests, so your project starts smoothly.
Many Mississauga kitchens date from the 1970s and 1980s, so we plan open layouts, custom cabinetry and quartz or granite counters. Moreover, we upgrade the electrical and plumbing rough-in for modern appliances.
Because moisture is the biggest risk, our bathroom renovations include waterproofed, curbless walk-in showers, quartz vanities and heated floors. Then we replace the plumbing fixtures, so everything works together.
When you want a secondary suite, a home theatre or a recreation room, we design and build it to code. As a result, you add living space or rental income, with fire separation, egress windows and framing done right.
Once your lot passes setback checks, we build a code-compliant concrete or masonry basement entrance. In addition, we install paver or asphalt driveways, retaining walls and drainage that keeps water away from the foundation.
Before laying hardwood, luxury vinyl plank, laminate or tile, we check and level the subfloor. Then we sand, refinish or restore existing floors where they are worth saving.
Because Mississauga homes from the 1970s and 1980s often have small panels, our electrical team upgrades service, lays out pot lights and installs EV chargers. We also rewire older systems to code, so your power stays reliable and safe.
Since basement flooding causes costly damage, we install backwater valves and sump pumps, and we handle rough-ins, drain repairs and fixtures. As a result, your plumbing works well and your basement stays better protected.
After careful prep and drywall repair, we apply premium, low-VOC paints with clean lines. Besides walls and trim, we can refinish cabinets for a fresh look.
Because many Mississauga kitchens are small and enclosed, we redesign the layout and open walls where the structure allows. We also add better lighting and storage, as our Mississauga kitchen renovation page shows.
First, we trace the source of the moisture. Then we correct drainage, add a sump pump or backwater valve where needed and finish the space with moisture-resistant materials. Because both trades matter, our plumbing team and basement renovation team work together.
Because legal suite rules confuse many owners, we review zoning, ceiling height, egress and fire separation before we design. Then we prepare the drawings and manage the permit with the City of Mississauga, so you avoid costly mistakes.
Because older houses often have outdated wiring and undersized panels, we assess the system first. Then we upgrade the service and add circuits for EV chargers and other modern loads, as our electrical services page explains.
Before you start, we check your project against City of Mississauga rules and tell you exactly what you need. When a permit applies, our architectural drawings and permit team prepares and submits it.
Instead of juggling five contractors, you deal with one team and one schedule, because we manage design, trades, inspections and clean-up. For larger projects such as additions, we also act as a full building construction company.
As a general contractor in Mississauga, we adapt our approach to each area, since housing varies from the lakeshore to the north end.
When you need a specific project type, visit our Mississauga kitchen renovation page or our Mississauga permit drawings page.
Because structural changes and legal secondary suites in Mississauga must follow the Ontario Building Code (OBC) and City of Mississauga zoning bylaws, our team handles the administrative burden for you.

It depends on the scope, because structural changes, plumbing or electrical alterations, new basement suites and additions usually need a City of Mississauga permit. However, simple cosmetic work like painting does not. Since rules vary, we check your project and handle the drawings and applications for you.
Because a legal suite must meet the Ontario Building Code, it needs a separate entrance, enough ceiling height, safe egress windows, fire-rated separation, sound control and suitable heating and ventilation. However, requirements vary by property and zoning, so we assess your home first. After that, we handle everything from drawings to final inspection.
Kitchen and bathroom renovations often take about 3 to 6 weeks once construction starts, although custom cabinets can add lead time. Meanwhile, whole-home remodels and legal basement conversions often take 8 to 16 weeks. Before you sign, we give you a precise timeline.
Because every project differs, the price depends on size, materials and how much structural, plumbing or electrical work you need. For example, a cosmetic refresh costs far less than a full redesign. After we visit your property, we give you a written scope and a clear estimate.
Yes, we have an office in Mississauga, and we work across the city, from Port Credit to Meadowvale and Malton. Because we also serve nearby cities such as Brampton, Oakville and Toronto, we can handle projects across the GTA.
Yes, and most condo buildings require board approval, a deposit and set work hours. Therefore, we prepare the paperwork, book elevators and follow your building’s rules from start to finish.
Yes, our team prepares architectural design and building drawings and also builds the project. As a result, nothing gets lost between the plan and the finished work.
Before you hire anyone, ask for a written scope and schedule, a clear explanation of permits and a plan for handling surprises. Also, check how the contractor manages trades and inspections. Although vague answers are a warning sign, we gladly answer all of these during your consultation.
Often, yes, although kitchen renovations are the main exception because you will lose the room for a while. Meanwhile, we protect the rest of your home and suggest a simple temporary setup. In addition, basement and exterior projects usually let you stay comfortably.
Many Mississauga homes from the 1970s and 1980s hide surprises such as dated wiring or old plumbing, so when we find a problem, we stop and explain what we found. Then we give you cost and timing options. Since nothing extra goes ahead without your approval, you always stay in control. You can also read more answers on our FAQ page.
When you tell us about your project, we explain your options in plain language. Then request your free quote or call us at (437) 210-0511. Meanwhile, you can read renovation tips on our blog.
