A whole-home renovation can give an older GTA property the layout, comfort and finish of a new home without asking your family to leave the neighbourhood it loves. It is also a major project with dozens of decisions and dependencies. Knowing what happens—and in what order—makes the process much easier to plan.
A realistic whole home renovation timeline is often six to twelve months from the first design meeting to the final walkthrough. Construction itself may take roughly 12 to 24 weeks for many projects, while additions, extensive structural changes or high-end custom work can push the schedule beyond that. The exact duration depends on the home, scope, approvals, selections and availability of labour and materials.
Here is a practical month-by-month view of a GTA design-build renovation.
Months 1–2: Discovery, Design and Budget Alignment
The project begins long before demolition. Your renovation team documents the existing house, discusses how your family uses it and translates your wish list into a workable scope. This is when you decide whether the project is primarily cosmetic or includes major moves such as removing walls, relocating a kitchen, adding bathrooms or finishing multiple levels.
Early design usually includes measured drawings, layout options, preliminary finish direction and a working budget. Structural engineers or other consultants may become involved when plans affect load-bearing walls, foundations or additions. A good design-build team will test ideas against the budget as plans develop, instead of designing an exciting project and pricing it only after every decision is made.
Use this stage to resolve the decisions that affect everything downstream:
- Which walls and rooms will change?
- Will plumbing fixtures stay near their current locations?
- Does the electrical service or HVAC system need upgrading?
- Which finishes have long lead times?
- Will the family live in the house or relocate temporarily?
The right partner matters. Review insurance, relevant experience, references, scope detail, communication practices and who will manage the site. Domilya’s overview of what to expect from a home renovation company is a useful starting point when comparing proposals.
Months 2–3: Construction Drawings, Selections and Permits
Once the concept is approved, the team develops permit and construction drawings. Cabinet layouts, lighting, plumbing fixtures, flooring, tile and appliances should also move toward final selection. Making choices now prevents crews from waiting for answers later.
Many whole-home projects require permits, especially where work affects structure, life-safety systems or the building envelope. Requirements vary by municipality and scope. Read Domilya’s Ontario renovation permit guide and confirm requirements with the local building department. Permit review can add several weeks, and revisions may add more.
During this pre-construction period, the contractor also creates the detailed schedule, orders long-lead products, confirms trade availability and sets site logistics. The schedule should show decision deadlines as well as build activities. A countertop cannot be templated before cabinets are installed; cabinets cannot be finalized before appliances are selected. Those links between tasks are what determine the critical path.
Month 3 or 4: Site Setup and Demolition
Before demolition, crews protect areas that remain, establish waste routes, isolate dust and disconnect affected services safely. Salvage items should already be labelled and removed. If you are staying in the home, temporary barriers and a clear access plan are essential.
Demolition commonly takes one to three weeks, depending on size and complexity. It exposes the actual structure and is often the first point where hidden conditions appear: old wiring, undersized framing, moisture damage, asbestos-containing materials or undocumented work. Responsible contractors pause, document the issue and explain options before proceeding.
Build a contingency into both budget and schedule. Older GTA houses can be full of surprises, and treating a contingency as optional makes every discovery feel like a crisis.
Months 4–6: Structural Work and Mechanical Rough-Ins
This is the least glamorous but most consequential phase. New beams, openings, stair changes, framing and additions are completed first. After framing passes the relevant inspection, plumbers, electricians and HVAC technicians install the systems that will sit behind the walls.
Typical work includes:
- relocating supply and drain lines;
- upgrading panels, circuits and lighting wiring;
- moving ducts or adding heating and cooling zones;
- installing bathroom exhausts and kitchen ventilation;
- running data, security or smart-home cabling; and
- completing insulation, air sealing and required fire separations.
Rough-in inspections must occur before drywall closes the walls. A failed or missed inspection can disrupt several following trades, so experienced project management is especially valuable here.
Months 6–7: Insulation, Drywall and the “Closed-In” Milestone
After rough-ins and inspections, insulation and vapour-control work are completed where required. Drywall is hung, taped, mudded and sanded. Rooms finally begin to feel like rooms again.
This phase can appear slow because joint compound needs drying time and a quality finish requires multiple passes. Rushing it often creates visible seams under paint and cabinetry. Primer typically follows, giving the team a consistent surface and making imperfections easier to spot.
Months 7–9: Floors, Cabinets, Tile and Finish Carpentry
Now the visible transformation accelerates. The exact sequence varies with materials and site conditions, but it generally includes flooring preparation, tile, cabinetry, interior doors, trim, built-ins and the first coats of paint.
Cabinet installation unlocks several dependent tasks. Countertops can be templated only after cabinet boxes are fixed and level. Fabrication may then take a few weeks. Backsplash, sinks and final plumbing connections follow. Custom millwork, specialty stone and imported fixtures can extend this stage if they were not ordered early.
Protect completed finishes as trades overlap. A clean, well-sequenced site is not only more pleasant; it reduces damage and rework.
Months 9–10: Fixtures, Final Paint and Commissioning
Electricians install devices and light fixtures, plumbers connect faucets and appliances, and HVAC equipment is balanced and tested. Hardware, glass, railings and final millwork details go in. Painters complete touch-ups after the last installations.
The contractor then reviews each room, creates a deficiency list and arranges final inspections. Homeowners should learn how new systems operate, receive warranties and care instructions, and confirm that permits are closed where applicable.
How Long Does a Whole-Home Renovation Usually Take?
For planning purposes, a substantial interior renovation may take three to six months of construction after design and approvals. A multi-floor gut renovation, addition or highly customized project may require six to nine months of construction or longer. Domilya notes that many home renovations fall within 12–24 weeks, with whole-home projects and additions commonly extending beyond 20 weeks. Explore its complete home renovation services to see how a coordinated design-build process works.
Common causes of delay include:
- permit comments or inspection availability;
- hidden structural, moisture or hazardous-material conditions;
- homeowner changes after construction begins;
- late fixture and finish decisions;
- custom or backordered products;
- trade dependencies and failed inspections;
- winter weather for additions or exterior work; and
- expanding the scope once walls are open.
The most controllable delay is late decision-making. Approve selections by the dates in the schedule, respond quickly to questions and route changes through the project manager.
Living Through a Whole-Home Renovation
Living on site can save temporary housing costs, but it is not always practical. Noise, dust, service shutdowns and restricted kitchen or bathroom access are unavoidable. Relocation is often the better choice when most levels are affected, mechanical systems will be offline, hazardous-material remediation is required, or young children and pets cannot be kept safely away from work.
If staying is realistic, agree on a livable zone, work hours, temporary kitchen, bathroom access, cleaning routine and advance notice for shutdowns. Store valuables and sentimental items off site. Keep one channel for decisions so instructions do not get lost between homeowners and trades.
Frequently Asked Questions
Can design and permits happen at the same time?
Some selections and procurement can continue during permit review, but the permit set must be sufficiently complete before submission. Starting demolition before approvals are in place can expose the homeowner to stop-work orders and costly redesign.
When should we order appliances and finishes?
Choose layout-critical appliances during design. Order long-lead cabinetry, windows, doors, fixtures and specialty finishes once specifications are confirmed. Your contractor should provide required-on-site dates.
How much contingency should we carry?
The right amount depends on the home and completeness of the plans. Older homes and structural projects need more protection than cosmetic work. Discuss a dedicated contingency with the contractor and keep it separate from upgrades you simply want.
Will a renovation finish on the exact date in the first schedule?
A professional schedule is a forecast based on known conditions. Good teams update it as information changes, explain impacts and protect the critical path. Ask how progress and changes will be reported.
Do we need to move out?
Not always. A contained main-floor project may be manageable, while a whole-home gut renovation often is not. Decide based on safety, access to essential services, project duration and your tolerance for disruption.
