    This is our second time hiring Alex and Heritage Home Design to replace the second half of our windows and the front door, and we were, once more, extremely pleased with the work done. Alex is professional and easy to communicate with. The Heritage Maximum window style is similar to our original wood windows and fits our home's traditional design. The new front door with full sidelites and semi-circular transom window significantly improved the look of our home. The installer Roman and his team worked diligently to match the original window and door trim, and did an excellent job. We definitely recommend Heritage Home Design.

    I am beyond impressed with Mohamed and his team. I would say the thing that really sets him apart from others is, he really truly cares about his clients, and goes well beyond the call of duty to ensure that things get done properly and on time. He also is the only contractor that I interviewed that took the initiative to come up with creative ideas on how to make my shower bigger in my very small dated en suite bathroom. Bottom line, he truly cares and has an amazing eye for design. The entire process from the beginning to the end was completely stress-free, and he was a joy to work with. He also has amazing trades that have been with him for many years, which says a lot about him. They were all very professional and respectful. The end result is an absolutely stunning beyond my imagination en suite bathroom. This could not have happened without Mohamed and his dedication and great ideas. He was always very communicative throughout the entire process and always onsite to supervise to ensure everything got done properly. He was truly a joy to work with. Needless to say, I would use him again in a heartbeat, and I would not hesitate to recommend him to family or friends.

    Install Vinyl, Linoleum or PVC floor-
    Although Declan was hired initially only for flooring, I expanded the scope of the project as he stated he was a GC. I was disappointed with the work. He was onsite for a few minutes some days and late a lot, even though we planned our meetings around my work schedule. The flooring/stairs was below standards I would expect from other contractors I worked with. Top nosing broke and tenant fell. He didn't even respond to texts or offer repair. He eventually agreed to refund 25% owing on the flooring as I would need to get someone else in to fix this but he never refunded this back. His subcontractor came 3 times and did not fix the stairs. Left the stairs unglued with my tenant's mover and my handyman tripping and falling. Ikea kitchen installer he hired left all boxes thrown in a closet. I was told that as he did not buy the kitchen, he did not have to dispose of them. Came back and cleaned poor grout lines and some grout was even missing. Left open drywall behind stove (not code).

    Install or replace roof-
    Outstanding Quality, Professionalism, and Fairness - Highly Recommend! I am absolutely thrilled with the incredible job Jin Tai Roofing did on our home. We hired them for a full replacement of our shingles, soffits, fascia, eaves troughs, and leaf guards. From the very beginning, their team was professional, efficient, and exceptionally fast. The true measure of their expertise came when they stripped the old roof and discovered significant, unexpected problems, including extensive rot that required replacing 23 sheets of plywood and repairing a damaged section of fascia. They handled this challenge seamlessly. What impressed me most was how fair and competitive their pricing was for this substantial extra work. There was no pressure, just a clear explanation and a very reasonable cost. The crew's work ethic was outstanding. They were incredibly clean, and you would never know how much work had just been done. The final result is simply amazing—the new roof, vents, and all the black

    We are very excited to introduce and share with you a unique new product called Security Window Film! This film will add security to your home, protecting you and your family from forced entry, vandalism and projectiles. It will also protect your children and family from possible injuries from broken glass from your windows and doors. Window security film operates by reinforcing your existing window glass with a sturdy, protective layer. This film, composed of high-tensile polyester and special adhesives, fortifies the glass pane, creating a resilient barrier. Upon application, it enhances the glass’s ability to withstand significant impact, making it more challenging for burglars to break through. In case the glass does break, the film holds the pieces together, maintaining the pane’s integrity. It’s designed to absorb and distribute impact energy, whether from attempted break-ins or environmental factors. While it doesn’t render the glass unbreakable, it significantly boosts the window’s resistance, adding a crucial layer of security to your home. Please visit securityfilmcanada.ca for more information.

    Install or renovate bathroom-
    We hired SLG to renovate and repair water damage in our ensuite bathroom as well as update a portion of our basement including a washroom. We are extremely pleased with the quality of the work, the speed that it was completed in and the flexibility of the team to deal with issues that arrive renovating a 1950's home. Electrical, framing and plumbing issues were quickly addressed and little extra touches were added with no additional expense to us to update our home. We can not say enough positive things about Jack, Joe and his team. They are the best most courteous people and we would not hesitate to hire them again or recommend them to anyone else. Great job and wonderful staff!!! Thanks.
