    Marge and Ted C. of Tillsonburg, ON

    Customer Testimonial

              The job you did was excellent and the install crew were very polite, hard and quick working. Adam was informative and it was exactly what took place. He had good knowledge of the product. The clean up was spotless, you would never know that they had been here. We were very happy with the quick response 1) to have Adam here so quickly and 2) having the repair done. We had lost a house sale due to the crack (with a home inspector) so it was very important to us to have it attended to quickly.Thanks again.

    Problem: This home's basement seeped water in and did not have an efficient sump pump. There was carpet directly on the concrete slab.

    Basement Wall Restoration London, ON

    Before
    After

    Problem:  This drywall had some water damage. Drywall is made of organic material, which means it can rot and grow mould when exposed to moisture and water- which can be likely within a basement environment! The studs that hold the drywall up are made of wood, which can also rot. When this happens, a musty odour is noticed. 

    Solution: Our Everlast Wall Restoration System is completely inorganic! We also use metal studs. The chair rail and baseboard are made of PVC. The wall panels themselves are made of a concrete board with a textured vinyl finish that never needs to be painted!
