We contacted Gab to undertake a two stage waterproofing repair both internally and externally over a number of weeks after storm damage had flooded the lower level of our house. At each stage of the process Gab was extremely reliable, used high quality products and best of all was a great communicator. I would highly recommend Gab for any of your waterproofing needs. If you want the job done right first time then Gab is the right person for the job.

GMG Waterproofing Solutions came up with a effective solution regarding water seepage issues which our insurance company would not cover.
Gab spent a considerable amount of time getting the preparation right, before applying and detailing a high quality membrane system that effectively stopped the issue causing any further damage. This business is locally based in the Blue Mountains, has outstanding knowledge, is customer focused, takes great pride in their workmanship and ensures the job is done right.

If quality workmanship, knowledge and customer service is anything to go by these days, then i would recommend you get in touch with Gab from GMG Waterproofing Solutions for your next upcoming waterproofing project. We honestly could not be happier with the service that this local water proofer has provided. Would recommend and use again.

We were recommended Gabs from GMG Waterproofing Solutions from our friends who previously used them and inquired to have their services undertake a number of external areas that required waterproofing. I found his workmanship to be of high quality, as he went above and beyond to ensure the job was done right, as a lot of man hours went into getting the job up to standard, due to the preparation that was involved.
Gab is customer focused, highly knowledgeable and actually took the time to listen on what our job required. A great experience using a local business, and one that i would recommend
