Professional Project Management, Open Books
Mighton Construction is a full-service general contractor serving homeowners throughout South Georgian Bay. We manage residential construction projects from initial consultation through final walkthrough — handling budgets, permits, schedules, trades, and quality control so you can focus on the decisions that matter to you.
Building well here takes local knowledge: our building departments, conservation authorities, soil conditions, and a shorter building season all shape how a project runs. With decades of work across Wasaga Beach, Collingwood, and the wider Simcoe County area — and a cost-plus, open-book approach that keeps every invoice in front of you — we keep your project moving and your budget transparent.

What we manage
Every Part of Your Project, One Accountable Team
As your general contractor, we take responsibility for the whole project — so you make the decisions that matter and we handle everything else. From the first permit to the final deficiency walkthrough, one team owns the outcome.
- Budget management — detailed cost tracking, regular financial reporting, and proactive communication about any changes.
- Permits & approvals — building permits, conservation authority applications, site plan approvals, and every required inspection.
- Trade management — scheduling, supervising, and quality-checking every subtrade, with relationships built over decades of local work.
- Material procurement — quality materials at competitive prices through established supplier relationships.
- Schedule management — a realistic timeline maintained through our shorter building season, with changes communicated promptly.
- Quality control — daily site oversight and a deficiency-free standard, so the work is checked before you ever have to ask.

Cost-plus, open-book
You Pay Actual Costs. You See Every Invoice.
A fixed-price contract builds the contractor’s risk into your price. Cost-plus works differently: you pay the actual cost of materials, labour, and subcontractors, plus a clearly defined management fee. Our interests are aligned with yours — we don’t profit from cheaper materials or hidden markups, so every decision is made on quality and value.
- Every trade and material invoice shared with you
- A management fee defined upfront, in writing
- No inflated allowances, no contingency padding
- A complete accounting of all costs at closeout

Client reviews
What Our Clients Say
We just finished building our new custom home with Mighton Construction, and honestly, the whole process was fantastic. The final craftsmanship is beautiful — you can tell they only work with the best, most reliable local tradespeople. If you’re looking to build new in Tiny Township, Wasaga Beach, or surrounding areas, you won’t regret hiring Mighton.
From our first conversations with Jeff and Adam, we knew they understood our vision for a multi-generational cottage. The skilled team demonstrated remarkable craftsmanship in every detail of our 3,500 sq ft home, and the quality is evident throughout. They built more than a cottage — they built the foundation for countless family memories.
