Condo Renovation Contractors in Toronto & the GTA
Planning a condo renovation Toronto or GTA-wide? Renovating a condo isn’t a smaller version of renovating a house — it’s a different job. Building rules, elevator bookings, noise windows, board approvals and concrete slabs all sit between your plan and the finished space. GMC Construction Inc. renovates condos across Toronto and the GTA with the paperwork and building coordination handled, on a fixed-price quote backed by a written workmanship warranty and 500+ completed projects.
Most delays in condo work aren’t construction problems — they’re approval problems. With 10+ years across the GTA and an owner who holds a Master’s degree in Structural Engineering, we know what property management will ask for, what can and can’t be moved inside a concrete building, and how to plan a schedule that survives contact with a condo board.
Our Condo Renovation Services
Condo Kitchens
Custom cabinetry planned around tight footprints, quartz countertops, and appliance packages sized for condo living — installed with building access rules built into the schedule.
Condo Bathrooms
Full bathroom rebuilds with proper waterproofing — critical in a building where a leak becomes your neighbour’s problem and your liability.
Layout Changes
Opening up a closed kitchen or reworking a floor plan. In concrete buildings some walls can move and some absolutely cannot — we establish which before anything is promised, and bring in a licensed professional engineer for stamped drawings when the building requires it.
Flooring & Sound Control
Most buildings mandate a minimum acoustic rating for flooring underlay. We install to your declaration’s requirements so you pass inspection and keep the peace downstairs.
Electrical & Lighting
Pot lights, under-cabinet lighting and added outlets — worked around concrete ceilings and slab conditions where you can’t simply run wire wherever you’d like.
Board Approvals & Building Coordination
Submission packages, insurance certificates, elevator bookings, service-corridor protection and working within permitted hours — handled so you’re not chasing property management.
How Much Does a Condo Renovation Cost in Toronto?
Condo renovations typically run 10–20% higher than the same scope in a house, because of building access requirements, protection of common areas, restricted working hours and material handling. Most GTA projects fall into these tiers:
Cosmetic Refresh
$15,000 – $30,000
Kitchen or Bathroom
$30,000 – $55,000
MOST COMMON
Full Unit Renovation
$60,000 – $110,000
With Layout Changes
$110,000 – $160,000
Luxury / Penthouse
$160,000+
These reflect complete, turnkey condo renovations in the GTA for 2026 — including permits where required, board submission packages, building protection, and all trades and finishes. A full unit renovation typically covers kitchen, bathroom, flooring, lighting and painting in a 700–1,100 sq ft unit.
Key factors that affect condo renovation costs:
- Building requirements — insurance certificates, deposits, elevator fees, restricted hours and common-area protection add real cost and time to every condo project.
- Layout changes — moving plumbing in a concrete slab is limited and expensive; keeping wet locations where they are saves substantially.
- Flooring acoustic rating — most declarations mandate a minimum underlay rating, which affects both material choice and installed cost.
- Access & logistics — a service elevator, loading dock and parking make a project cheaper; a walk-up or single elevator with tight booking windows makes it slower.
- Finish level — cabinetry tier and countertop material drive the budget in condos exactly as they do in houses.
We assess your unit and read your building’s rules before quoting, so the number accounts for the real constraints. You get a fixed-price, itemized quote after a free in-suite consultation.
Why Choose GMC for Your Condo Renovation?
Structural expertise behind every layout change
In a concrete building, knowing which walls are structural and which are partition is not a guess. GMC is led by an owner who holds a Master’s degree in Structural Engineering — so layout changes are assessed properly before they’re proposed.
We handle the building paperwork
Submission packages, insurance certificates, deposits, elevator bookings and corridor protection — prepared and managed by us, so approvals move instead of stalling in someone’s inbox.
Waterproofing that protects you
A bathroom leak in a condo isn’t just your damage — it’s the units below and your liability. We waterproof to a standard that assumes the worst, because in a stacked building the stakes are higher.
Fixed-price quotes
Condo budgets get squeezed by fees most homeowners don’t expect. We price the building requirements into the quote up front — so the number you agree to is the number you pay.
Respectful, tidy worksites
You share hallways, elevators and walls with neighbours. We protect common areas, work within permitted hours, control dust and clean daily — so your renovation doesn’t become the building’s complaint.
Licensed, insured, proven
Fully licensed and insured with WSIB coverage — the documentation every condo board requires before you get approval — plus 500+ completed projects and a 5.0-star rating from 85+ Google reviews.
What Makes Condo Work Different
Four constraints shape every condo renovation. Understanding them before you start is the difference between a smooth project and a stalled one.
Board Approval Process
Most buildings require a submission package with drawings, contractor insurance and a deposit before work starts. Review can take weeks — starting it early is the single best thing you can do for your schedule.
Concrete Slabs & Plumbing Limits
You can’t cut drainage into a post-tension slab. Wet locations are largely fixed, which means kitchen and bathroom layouts have real limits — and anyone promising otherwise hasn’t checked.
Acoustic Requirements
Declarations typically mandate a minimum sound rating for flooring underlay. Installing below spec can mean being ordered to tear it out — so we build to your building’s number, not a generic one.
Access, Hours & Logistics
Elevator bookings, loading windows, permitted working hours and debris removal routes all shape the schedule. We plan deliveries and disposal around them rather than losing days to a missed booking.
Condo Projects We Take On
Most condo projects in the GTA fall into one of three shapes. Here’s what each typically involves:
Refresh & Update
Flooring, paint, lighting, fixtures and cabinet refacing without moving anything. The fastest, least disruptive way to modernize a unit — and often the easiest to get approved.
Full Unit Renovation
Kitchen, bathroom, flooring, lighting and finishes throughout, with wet locations staying put. The most requested scope — a complete transformation without fighting the slab.
Layout Reconfiguration
Removing partitions to open the plan, reworking the entry or combining spaces. Requires structural assessment and board approval — and it’s where our structural background matters most, with a licensed professional engineer engaged for stamped drawings where required.
How Long Does a Condo Renovation Take?
A cosmetic refresh typically runs 2 to 4 weeks on site. A kitchen or bathroom takes 4 to 6 weeks. A full unit renovation runs 8 to 12 weeks, and layout changes add 2 to 4 weeks on top. Board approval happens before any of it and commonly takes 3 to 8 weeks — which is why we prepare and submit that package as soon as the design is settled.
