A renovation crew that actually shows up prepared
Most of the calls we used to get — before we switched to email so nobody has to leave a voicemail into the void — started with the same story. A reno that stalled halfway, a contractor who quoted low and then found 'extra work' every week, or a basement that got finished without anyone checking where the water was actually coming from. We run jobs differently. We look at the house first, not the invoice.
We work on what the GTA actually has
Sixties bungalows in Oshawa, seventies split-levels in Whitby, brand-new builds in Ajax with builder-grade everything — the fixes are different for each. We don't apply a Toronto condo playbook to a Durham slab-on-grade house.
Freeze-thaw changes how we build
Ontario winters push and pull at foundations, siding, and anything attached to the outside of a house. We account for that in additions and exterior tie-ins, not just in the parts you can see.
One crew, one point of contact
You're not handed off between a salesperson, a project manager, and a sub you've never met. The person who quotes the job is reachable by email through the whole thing.
The reno industry has a trust problem, and homeowners pay for it
Ask around Durham or Peel and you'll hear the same complaints — a deposit taken, a crew that vanishes for three weeks, drywall closed up over a problem nobody flagged. Renovation work in older GTA neighbourhoods runs into knob-and-tube wiring, cast iron plumbing, and foundations that were never meant to be finished spaces. Skip that inspection step and you're paying to redo it in five years.
We slow down at the start so the job doesn't stall later
Before we quote anything, we look at what's actually there — moisture, structure, wiring, the age of the house. You get a written scope that says what we found and what it costs to deal with it properly. If something needs an electrician or a permit, we say so up front instead of discovering it after the drywall's up.
What we build and fix
Six trades, one crew. Pick the room, we'll walk you through it.
Basement Finishing GTA
Turning damp, unused square footage into a room people actually use — done with moisture control first, finishes second.

Learn moreFlooring Installation GTA
Hardwood, engineered, tile and LVP, installed with an eye on subfloor condition and how Ontario humidity moves wood.
Learn moreGeneral Contracting GTA
One crew managing the whole job — trades, sequencing, permits — instead of you coordinating five different companies.
Learn moreHome Additions GTA
Second-storey additions and rear extensions tied properly into an existing structure and foundation.
Learn moreKitchen Renovation GTA
Layout changes, cabinetry, and full kitchen rebuilds that work around load-bearing walls instead of pretending they're not there.

We're not the biggest outfit in the region and we're not trying to be. We're trying to be the one you don't have to think about twice.
Straight answers
If a wall's load-bearing or a basement's got a water problem, we tell you before we quote, not after we open it up.
We work the GTA, not just one postal code
Oshawa is home base, but the crew moves through Durham, Peel, Halton and York on a regular rotation.
Built for the climate here
Materials and methods chosen for freeze-thaw cycles and humidity swings, not a showroom in a warmer province.
Timelines that hold
We sequence trades so drywall doesn't sit waiting on an electrician for two weeks.
Tools and trade knowledge, not scripts
The person quoting your job has swung a hammer on one like it. This isn't a call centre operation.
Written scope before a shovel moves
You know what's included, what's not, and what triggers a change order before work starts.
How a job with us actually runs

Questions we get asked before a first quote
Do you work outside Oshawa?
Yes. Oshawa is where we're based, but we run jobs across the Greater Toronto Area — Durham, Peel, Halton, York and the City of Toronto. Tell us your city when you email and we'll confirm scheduling.
Can I reach you by phone?
We handle everything by email. It keeps a written record of what was discussed and quoted, which protects both sides. Email us or request a quote through the site and we'll respond directly.
Do you pull permits?
Where the scope requires it under the Ontario Building Code — additions, structural changes, most basement finishes — yes. We flag this during the walkthrough, not as a surprise line item later.
What kind of houses do you work on?
Everything from postwar Oshawa bungalows to new-build subdivisions in Ajax and Whitby. Older housing stock and new construction need different approaches, and we adjust for that.
How do freeze-thaw cycles affect a renovation?
Ontario winters expand and contract foundations, exterior walls, and anything tied into them. It matters most on additions and basement work, where we build in drainage and insulation choices meant for this climate, not a generic spec sheet.
