Older Home, New-Build Performance
A whole-home renovation transforms an existing house from the inside out. At Mighton Construction, we take on comprehensive projects that go well beyond cosmetic updates — reconfiguring layouts, upgrading structural systems, replacing mechanicals, improving insulation, and delivering a home that looks and performs like a new build while retaining the character and location you value.
Many homes in South Georgian Bay were built as seasonal cottages, or date to an era when building standards were very different. These homes often have solid bones but outdated systems, poor insulation, inefficient layouts, and finishes that no longer meet the owners’ expectations. A whole-home renovation lets you keep the property and location you love while bringing everything up to modern standards.
When it makes sense
When a Whole-Home Renovation Makes Sense
Older homes here often have great bones but no longer fit how people live. A whole-home renovation is the right move when the issues run deeper than finishes:
- Converting a cottage to year-round living — insulation, heating, windows, and foundations upgraded for four-season comfort
- Aging-in-place modifications — main-floor primary suites, accessible bathrooms, wider doorways, and single-level living
- Outdated systems — knob-and-tube wiring, galvanized plumbing, and oil furnaces replaced with modern, efficient alternatives
- Layout improvements — opening up floor plans, adding natural light, and creating spaces that suit how you actually live
Built for South Georgian Bay
South Georgian Bay Considerations
Renovating in our climate uncovers challenges specific to older local construction — inadequate vapour barriers, insulation well below current energy codes, foundations never meant for full basements, and water management near Georgian Bay or high water tables. We anticipate these and plan for them before demolition, not after. We also manage the permit process across Collingwood, Wasaga Beach, The Blue Mountains, and Clearview Township — each with its own requirements and timelines.
Open-book pricing
Transparency Matters Most When Walls Come Open
Unforeseen conditions are a reality of whole-home work — which is exactly why we run every project cost-plus and open-book. You see the actual invoices, every change is priced and approved in writing before work proceeds, and there is never a number you can’t trace.
- Comprehensive assessment of structure, systems, and envelope before we price anything
- Detailed scope and budget, reviewed with you line by line
- Actual trade and material invoices, visible to you throughout
- A complete accounting of project costs at closeout
Why Mighton
A Renovation Team That’s Actually There

Our Whole-Home Renovation Process
Comprehensive Assessment
We conduct a thorough evaluation of your home's structure, foundation, mechanical systems, insulation, and building envelope to identify what needs to be replaced, upgraded, or preserved.
Design & Scope Development
Working with you and your design team, we define the full scope — layout changes, structural modifications, system upgrades, and finish selections — and develop a detailed budget.
Permitting
We prepare and submit building permit applications, coordinate with engineers, and manage any required inspections or approvals.
Selective Demolition
We carefully strip the home back to the required level — sometimes to the studs, sometimes preserving select elements — while managing hazardous materials like asbestos or lead paint if present.
Rebuild & Finishing
Structural repairs, new mechanical systems, insulation upgrades, drywall, flooring, cabinetry, and all finishing trades are coordinated and completed by our team.
