A valley, two hills, and three very different kinds of renovation
Bolton is built around the Humber, with the old village in the valley and the newer neighbourhoods climbing the North Hill and South Hill. Where your house sits changes what a renovation involves.
Down in the core, some of the houses have been standing since Bolton was a mill town. Beautiful streets, and behind the plaster you can meet wiring, plumbing and framing from another era. Properties close to the river can also fall under conservation authority jurisdiction, which means valley land rules get checked before anything structural is planned. Senso Design confirms that early, not after drawings are paid for.
Up on the hills it is a different conversation. The eighties and nineties subdivisions are hitting the age where the kitchen, the bathrooms and the basement all raise their hands at once, and the newer phases east of Highway 50 mostly want builder grade finishes swapped for something chosen on purpose. Same town, three different playbooks, and we carry all three.


The main floor is where Bolton homes earn their update
The classic Bolton project starts with a kitchen that still works and a family that has outgrown the way it is laid out. Two decades of cooking in a closed off room, a dining area nobody eats in, and a wall between them that may or may not be doing anything structural.
Our answer usually pairs a new kitchen with a rethink of the whole main floor. Where the wall can come out, an island takes its place. Cabinetry comes from Senso Design’s own facility in Markham, built on German and Italian equipment, which keeps the longest lead time of the project in our hands.
A mid range kitchen lands between $25,000 and $60,000 before HST, and taking out a load bearing wall adds engineering and steel on top. We tell you which kind of wall you have before you commit to the dream, not after.

What a renovation costs in Bolton
Figures below come from Senso Design’s completed 2026 projects, before 13% HST. The complete method lives in our renovation cost guide.
Read it this way: the scope you choose moves the number far more than the town you live in. Budget $50 to $95 per square foot to refresh finishes, $100 to $130 for a proper mid range renovation, and $150 to $300 when structure and premium materials enter the picture. Bolton’s housing stock leans toward roomy detached homes, which is why whole home numbers here look bigger than a downtown semi’s.
| Project | Typical range | What pushes it higher |
|---|---|---|
| Kitchen renovation | $25K to $60K | Load bearing wall out, custom cabinetry |
| Standard full bathroom | $12K to $25K | Relocating fixtures, glass and stone upgrades |
| Primary ensuite | $25K to $70K+ | Curbless shower, heated floors, double vanity |
| Basement, mid range with bath | $55K to $80K | New drains cut into the slab |
| Legal second suite | $90K to $140K+ | Egress, fire separation, separate entrance |
| Whole home, 2,600 sq ft | $260K to $338K | Structural work, premium finishes |
Put a ballpark on your Bolton home
Choose a size and a scope. The math behind it is the per square foot table above with 13% HST stacked on, so the second number is the honest one.
Per square foot: $50 to $95 cosmetic, $100 to $130 mid range, $150 to $300 high end or gut. Built from Senso Design projects completed across the GTA and Caledon side of the region.
Treat this as a compass, not a contract. The real figure comes from walking your home, free and without obligation.
Permits in Bolton run through the Town of Caledon
Bolton is Caledon’s largest community, so your building permit comes from the Town of Caledon, and homes near the river can involve one extra checkpoint.
- Caledon issues the permit for structural work, plumbing or electrical changes, basement finishing, added bathrooms and additions. Cosmetic swaps in the existing layout generally proceed without one.
- Valley land properties get an extra look. Near the Humber, the conservation authority can have jurisdiction over additions and structural changes. Senso Design checks that mapping before design money gets spent.
- Second suites follow the bylaw and the Building Code, with egress, ceiling height, fire separation and parking deciding what is possible.
- The old village keeps secrets. Core homes can carry generations of wiring and plumbing decisions, so we open budgets with a real contingency instead of optimism.
- Hill subdivisions are the easy customers. Eighties and newer construction rarely ambushes anyone, which is why budgets up the hill tend to finish where they started.
- Senso Design files the permit under our own name and meets every inspector, so the Town of Caledon deals with us, not with you.
Permit and conservation review time gets written into the schedule before demolition is booked. Discovering a review period mid project is the single most avoidable delay in renovation work, so we simply refuse to let it happen.

The price you agree on before we start is the price you pay.
Senso Design has spent two decades becoming one of the Toronto home renovation experts people refer to their own family, and the formula has never changed. Design and build under one roof, and nobody quoting what somebody else has to deliver.

Caledon permits, our problem
Filed in our name, inspected with us on site.
“Another contractor quoted me a lot less.“
Three questions usually explain the gap. What are the cabinet and tile allowances? Are permits, bins and disposal inside the number? Is HST included? Cheap quotes get expensive precisely where they went quiet.

How a Bolton renovation runs
What clients say
A 4.9 rating across 115+ Google reviews, HomeStars Best of Awards five years running, and Best of Houzz in 2025 and 2026.
We did a major renovation, kitchen, multiple baths, family room, and still love the work they did. From incorporating new ideas to sticking to budget and timelines, they were on point. Their after care has also been superb.
The teams were well coordinated, small issues were resolved quickly, and the final cost matched the original quote. That last part is rarer than it should be.
Mark patiently explained everything to us, from planning, design, choices of materials and timeline. Everything went extremely well, from a great design and layout to the hardworking, efficient, well mannered construction crew. The finished product looks fantastic.

Bolton renovation questions, answered
How much does a home renovation cost in Bolton?
Using Senso Design’s 2026 figures, plan on $50 to $95 per square foot for a cosmetic refresh, $100 to $130 for a mid range full renovation, and $150 to $300 for high end or gut work, before HST. Bolton’s typical detached home is on the larger side, so a mid range whole home renovation of 2,600 square feet works out to roughly $260,000 to $338,000. One room at a time is gentler, a kitchen at $25,000 to $60,000 or a full bathroom at $12,000 to $25,000.
Who issues building permits in Bolton?
The Town of Caledon, since Bolton is part of Caledon rather than a municipality of its own. Structural changes, plumbing and electrical alterations, basement finishing and additions all need one. If your property sits near the Humber valley, conservation authority approval can be a second gate for additions and structural work. Senso Design confirms both before the design phase, and every application goes in under our name.
Is it worth renovating an older home in the Bolton core?
Usually, and often spectacularly. The village core has character no subdivision can copy, and buyers pay for it. The honest part: budgets there need breathing room, because opening century old walls reveals the decisions of every owner before you. Carry 15 to 20 percent contingency in the core versus 10 to 15 up on the hills, and choose a contractor who prices the surprises in from the start.
Can you open up the main floor of a 90s Bolton home?
This is the most requested project on the hills, and yes, nearly always. The question is whether the wall between kitchen and dining carries load. If it does, an engineered beam takes over, which adds engineering and steel to the budget but rarely kills the project. We assess the structure during the free consultation, so you know which scenario you are in before falling in love with a layout.
How long does a whole home renovation take in Bolton?
Plan on 3 to 6 months of construction for a full house, with design and the Caledon permit stage in front of it. Single rooms move faster, roughly 2 to 4 weeks for a bathroom, 3 to 5 for a kitchen and 4 to 8 for a basement. Where conservation review applies near the valley, that window is scheduled up front too.
Do you handle design as well as construction?
That is the whole point of how Senso Design is built. Designers, project managers and crews under one roof, with cabinetry produced in our own Markham facility. You approve layouts and 3D renderings before the quote is final, and the people who drew the plan are accountable for delivering it.
Can we stay in the house while you work?
For a bathroom, a basement or even a kitchen with a temporary setup, most Bolton families do. A whole home renovation is a different animal, and we would rather tell you at the quote stage that moving out for part of it will save your sanity and shorten the build. You will always get that answer straight, before you sign.
What does the fixed price actually cover?
Everything on the itemized list you sign, labour, materials at the allowances you chose, permits, disposal and project management. It is the amount due at handover, full stop. Anything you add mid project becomes a written change order with its own price, approved by you before it happens. Financing up to $100,000 is available if the timing of the spend matters.
What is the first step?
A free consultation at your Bolton home. We look at what you want to change, point out where the money concentrates, and send a budget range within five business days. If the numbers work for you, design starts. If they do not, you have lost nothing but an hour.
