My husband and I are very impressed with the turbo power cleaning, calcium removal, silicone restoration and grout colour seal (with 15 year guarantee) done in our ensuite. The work was done by Andy Knights (GroutPro Mindarie) and we would highly recommend him to anyone looking to have similar work done in the bathroom. Andy is very professional and extremely helpful. The GroutPro maintenance cleaning products are pH neutral, work fantastic and can be used around the house. Thanks Andy!!
