One General Contractor for Your Whole-Home Renovation

    A whole-home renovation is different from updating one kitchen or bathroom. Once work reaches several rooms, walls are moving and electrical, plumbing, flooring and finishes overlap, every decision affects the next trade.

    Deomax Group provides home renovation and general contracting services in Mississauga and across the GTA, coordinating the project under one scope rather than leaving homeowners to manage separate contractors themselves.

    We can coordinate demolition, framing, drywall, electrical, plumbing, flooring, kitchens, bathrooms, trim, painting and finishing as part of one renovation plan. Where drawings, permits or specialized trades are required, those pieces are coordinated with the construction schedule.

    The result is one project with a defined scope, sequence and point of responsibility from the first walkthrough through final finishing.

    What Does a Full Interior Renovation Include?

    A full interior renovation may cover most or all of the finished space inside a house. The exact scope depends on what can stay and what needs to change.

    Typical whole-home renovation work can include:

    • Interior demolition and removal of old finishes
    • Wall removal and new interior layouts
    • Framing, drywall and insulation
    • Electrical and lighting upgrades
    • Plumbing changes and fixture installation
    • Kitchen renovation and cabinetry
    • Bathroom renovations
    • Flooring throughout the home
    • Staircases, railings, doors, trim and baseboards
    • Painting and final finishing
    • Basement renovation when included in the project

    Some homes need mostly cosmetic work while others are stripped back much further. That difference in scope has a major effect on both cost and schedule.

    How We Phase a Whole-Home Renovation

    A large renovation needs to be sequenced so trades are not working against each other and finished work is not damaged by work that should have happened earlier.

    1. Planning and scope: we walk through the house, establish what is changing and identify structural, electrical, plumbing and finish requirements.
    2. Design and pre-construction: layouts, material selections, drawings and required approvals are addressed before the affected work begins.
    3. Demolition and rough construction: demolition is followed by framing and structural work where required.
    4. Mechanical rough-ins: electrical, plumbing and other services are completed while walls and ceilings are accessible.
    5. Close-up: insulation, drywall and preparation work bring the interior back together.
    6. Finishes: kitchens, bathrooms, flooring, doors, trim, painting, fixtures and other finish items are installed in sequence.
    7. Final review: remaining details are reviewed before project completion.

    Can You Stay in the House?

    For a limited renovation, sometimes. For a true whole-home renovation, moving out is usually the more practical option.

    If the kitchen and bathrooms are unavailable, utilities need to be shut off at different stages, or demolition affects most of the main living space, trying to live around the work can create significant disruption. We discuss this during planning so you know which parts of the house will be usable and when.

    How Much Does a Home Renovation Cost in Mississauga and the GTA?

    There is no useful single price for a whole-home renovation because replacing finishes in an existing layout is fundamentally different from opening walls and rebuilding the interior. The following are 2026 GTA planning ranges, not a quotation for your property.

    Cosmetic Renovation

    Rough planning range: $50–$100+ per sq. ft.

    Typically involves keeping the existing layout while updating items such as flooring, paint, trim, doors, lighting and selected fixtures.

    Full Interior Renovation

    Rough planning range: $100–$225+ per sq. ft.

    May include a new kitchen, multiple bathrooms, new flooring, electrical and plumbing work, extensive finish replacement and some layout changes.

    Gut or Structural Renovation

    Rough planning range: $225–$350+ per sq. ft.

    Applies when substantial areas are opened to the studs, layouts change significantly or the project includes structural work, major mechanical upgrades and higher-spec finishes.

    Planning ranges current as of September 2026. Actual pricing depends on the size and condition of the home, demolition required, structural work, kitchen and bathroom count, electrical and plumbing scope, finish selections and other site-specific conditions. A written project estimate is prepared after the scope has been reviewed.

    Fixed Scope, Payments and Change Orders

    A renovation contract should make it clear what you are paying for before construction begins. The written scope should identify the work being completed, significant materials and allowances, payment terms and the project schedule.

    What Does a Fixed-Price Contract Cover?

    A fixed price applies to the work and selections defined in the contract. That is why the scope needs to be detailed: flooring, cabinetry, fixtures, demolition, trade work and other included items should not be left to assumptions.

    Items specifically excluded from the contract, owner-requested additions and conditions that could not reasonably be confirmed before opening the building may need separate treatment.

    How Do Change Orders Work?

    If you decide to add work, upgrade a selection or change an agreed part of the renovation after the contract is signed, the change should be documented before that extra work proceeds. The change order records what is changing and any effect on price or schedule.

    How Are Payments Handled?

    The contract sets out the deposit and subsequent payment schedule rather than leaving payments informal. Larger renovation projects are typically divided into defined stages so the payment structure follows the progression of the work.

    This makes the financial side of the renovation visible from the outset instead of relying on verbal agreements as construction progresses.

    Who Is Actually Working in Your Home?

    Whole-home renovation requires several different skills. Some work can be completed by the general renovation crew while specialized scopes require the appropriate trades.

    Rather than asking the homeowner to independently schedule each contractor, the general contractor coordinates the sequence.

    Depending on the project, that may include:

    • Demolition, framing, drywall and carpentry crews
    • Electricians
    • Plumbers
    • HVAC trades
    • Tile and flooring installers
    • Cabinet and countertop suppliers/installers
    • Painters and finishing trades
    • Structural or design professionals when required by the scope

    The important distinction is accountability: the individual trades may change from stage to stage, but the project remains coordinated through the general contractor.

    Insurance, WSIB and Our 2-Year Installation Warranty

    A contractor is responsible for more than the finished appearance of a renovation. The business and the trades working on the project also need to be managed properly behind the scenes.

    Deomax maintains appropriate business insurance and manages WSIB requirements applicable to the people and subcontractors working on our projects. Where subcontracted construction work requires clearance, that documentation forms part of proper trade management.

    Our renovation work also includes a 2-year installation warranty. The written agreement identifies the warranty applicable to your project so you know what is covered after construction is complete.

    If you are comparing general contractors in Mississauga, ask each company about insurance, trade responsibility, warranties and who is accountable for subcontractors before comparing the bottom-line quote.

    Whole-Home Renovation & General Contractor FAQs

    A whole-home renovation can include demolition, layout changes, framing, drywall, electrical and plumbing work, kitchens, bathrooms, flooring, staircases, doors, trim, painting and other interior finishes. The exact scope depends on which parts of the existing home are staying and which are being rebuilt.

    As a rough 2026 GTA planning guide, cosmetic renovations may fall around $50–$100+ per sq. ft., more complete interior renovations around $100–$225+ per sq. ft., and extensive gut or structural renovations around $225–$350+ per sq. ft. These are planning ranges rather than project quotes; the final cost depends on the house, scope, finishes and amount of structural or mechanical work required.

    It depends on the size and complexity of the project. A renovation that keeps most of the existing layout can move considerably faster than a full gut renovation involving structural work, several bathrooms, a kitchen and major electrical or plumbing changes. We establish the sequence and project schedule once the actual scope is known.

    Sometimes, but a full interior renovation often makes moving out the more practical choice. If kitchens and bathrooms are unavailable, utilities are interrupted or construction affects most of the home’s living areas, remaining in the property can be difficult. We discuss occupancy during the planning stage.

    The contract should define the work, included materials or allowances, trade scopes, payment terms and other agreed project items. Work outside that documented scope should not simply be assumed to be included, which is why a detailed written agreement is important on a large renovation.

    Changes should be documented through a change order before the additional or different work proceeds. The change order identifies the revised scope and any impact it has on the price or project schedule.

    Whole-home renovations require specialized trades, so some stages are completed by the appropriate subcontractors or specialists. Deomax coordinates those trades as part of the overall general contracting scope rather than requiring the homeowner to independently schedule each part of the project.

    Yes. Deomax provides a 2-year installation warranty on its renovation work. The applicable warranty terms are identified as part of the project agreement.
