    Why Our Customers Choose Us

    blue tic Kim, Scarborough star

    A 4-story townhouse needed fresh caulking around all doors and windows. Not an easy job. Tom came to look at the job within a day or two of making the request. His experience and expertise set me at ease. The work was done by Jerry. He worked hard. He was polite, efficient and the work was of very high quality. It looks fantastic. I highly recommend this company.

    Tom was a pleasure to work with, he provided me with a quote on a timely manner and was in touch soon after to schedule the work.
    Showed up on time! And Jerry did clean and effective replacement of the window caulking.

    blue tic Eagle, Oakville star

    Tom and his team were very professional courteous. They executed all the work and cleaned up after it was completed. It has been couple months already and the job still looks great and clean. I would recommend this company to my friends and family who needs this service.
