Sinco did a fantastic job sealing my kitchen and bathroom countertops and doing some minor repair. Highly recommend.

Sinco Marble and Granite Countertop is really good. Last week we had scheduled cooktop installation from Miele and the contractor came with cooktop and found the current granite countertop is too small for it so he recommended HomeStars and we immediately went to the website and found Sinco Marble and Granite Countertop. we send quick message to this company and within 30minutes we got reply and two guys from this company came with all equipments and started the service immediately and after 2hours the job was done perfectly. They covered my floor and countertops when they were cutting the granite to minimize the dust and vacuum the dust for us. Very nice job and after that we called Miele contractor and he said the cutting job is perfectly done so my new cooktop fits perfectly. Thank you so much Sinco Marble and Granite Countertop! Your guys are awesome.
Great workmanship. Very professional. Knowledgeable and patient with our needs. On time and no surprises. Thanks Sinko.
Not a huge job, but we needed our granite countertop cut to fit our new sink. Got a good price from Sarmen and crew. They did a great job, cleaned up, and communicated well throughout. I'd use them again.
Very happy with quality of material, meticulous attention to detail and with their wonderful customer service. It was a great experience to have dealt with the awesome family and staff of Sinco. We will definitely refer them to all. Teresa and Tony

Worth checking yourself
Their public evidence comes from a single source. Look them up on another site before deciding.
No credentials are shown here and the business has not claimed this profile. Ask to see certificates and insurance directly.
Trade licensing in Canada is set by each province or territory. Electrical, gas and plumbing are licensed trades almost everywhere (for example ESA for electrical and TSSA for gas in Ontario), so check your provincial regulator that the contractor is certified for the work before you hire.
A construction lien is a real risk: in every province an unpaid subcontractor or supplier can register a lien against your home even if you already paid the main contractor. Hold back the statutory amount (commonly around 10%) and get signed lien waivers as you pay.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
