Benefits
Why Markham Contractors & Developers Choose Bluestone
50+ York Region post-construction projects and a simple reputation — the cleaner Markham GCs hand a friend's number for.
Comfortable On An Active Site
Our crews know how to work a live or just-finished build — proper PPE, site safety protocols followed, and clean phases coordinated with your GC's supervisor so we never cross the trades.
HEPA Dust Removal
Fine construction dust travels everywhere and lingers in the air. We run HEPA-filtered vacuums and a top-down capture method so the particulate actually leaves the building, including out of the HVAC, rather than getting stirred back up.
We Speak GC
We deal directly with Markham developers, general contractors, and PMs. We read a schedule, fit between trades, and understand exactly what a missed handover date costs you.
Mobilize Fast
Markham's pipeline does not wait. From our east-GTA base we can get a post-construction crew moving on short notice to hit your occupancy, inspection, or handover date.
Room-By-Room Checklist
Every clean follows a written, room-by-room checklist we have refined over 15+ years of site work. The supervisor signs off at the end and nothing gets left behind.
LEED-Compatible Cleaning
For LEED-certified or LEED-pursuing Markham projects, we use low-VOC, green-certified products and follow the LEED construction IAQ management guidelines, with product documentation on request for your submission.
FAQ
Frequently Asked Questions
What Markham developers, GCs, and owners ask us most about scope, scheduling, and getting a crew on site.
What's included in post-construction cleaning in Markham?
Bluestone Janitorial's Markham post-construction cleaning typically includes: removal of construction debris and packaging; HEPA vacuuming of all surfaces including walls, ceilings, and floors; cleaning of all windows, glass, and mirrors; cleaning inside all cabinets, closets, and built-in storage; cleaning and polishing all fixtures and hardware; scrubbing all bathrooms; mopping and polishing hard floors; and a final walkthrough with the site supervisor to confirm completion.
How soon can Bluestone Janitorial start post-construction cleaning in Markham?
From our east-GTA base we can usually have a crew on a Markham site within 24-72 hours, depending on scope and what is already booked. If your occupancy date is tight or the project is large, call us early so we can hold the dates and staff it properly.
Who typically books post-construction cleaning — the general contractor or the property owner?
Both. Bluestone Janitorial works with general contractors who include post-construction cleaning in their project scope, as well as property owners and tenants who arrange cleaning directly after construction is complete. We're flexible and can coordinate directly with whoever manages site access.
Do you offer LEED-compatible post-construction cleaning in Markham?
Yes. For Markham projects pursuing LEED certification, Bluestone Janitorial uses low-VOC, Green Seal or EcoLogo certified cleaning products and follows LEED for New Construction Indoor Air Quality (IAQ) Management Plan guidelines. We can provide documentation of products used if required for your LEED submission.
Does Bluestone Janitorial serve all of Markham for post-construction cleaning?
Yes. We cover all Markham construction and development areas including Cornell, Unionville, the Highway 7 tech corridor, Markham Village, Buttonville, Cathedraltown, and commercial and industrial projects near Markham Stouffville Hospital and Highway 407.
