We are WSIB cspaat compliant for your protection, and we guarantee all of our work. We are dedicated to maintaining a healthy and sustainable environment, which is one reason why we use only environmentally sensitive products in all or our sealing and commercial concrete power washing procedures. We have made it a point to research many sealing products to ensure our customers that we are using the most durable and safe sealants and stains. The surface is first cleaned with power washing and then sealed. If it is sealed without cleaning, it will always look dirty and the sealant will not penetrate and adhere properly. It will start to peel and flake and not last as long as it should. Our commercial concrete power washing and sealing is designed to be an industry leader in the field. We clean the exterior of low-rise commercial buildings and fences as well as underground parking garages. We completely remove graffiti for a sparkling fresh surface.
