Renovation Contractor in Markham
Markham blends heritage streets in Unionville with large, newer detached homes in Cornell, Berczy, and Wismer — and both want more from their space. Blackstone General Contracting renovates Markham kitchens, bathrooms, and basements and fits out its commercial and professional spaces, with the trade coordination that larger, more finished homes demand.
Markham's newer detached homes are big and well-built, which changes the renovation conversation: it's less about fixing problems and more about upgrading finishes, opening kitchens to family space, and finishing large basements as in-law suites or media rooms. Older Unionville and Markham Village homes ask the opposite — careful work that respects an established house.
Markham also has a dense base of professional and retail businesses along its commercial corridors, and our commercial arm handles office and professional-suite fit-outs there, scheduled around business hours.
Equally at home upgrading finishes in Markham's large newer builds and working carefully in established Unionville homes.
