Cal Coast Waterproofing

Mike is meticulous in his process and does a superb job. He’s like the leak whisperer, somehow can understand where they originate, and if he can’t figure it out, he goes step by step until the leak is found. We had him waterproof our inner courtyard, it leaked for decades, it was the second time we’ve had it done (first time by another guy), and it’s fixed, we no longer have a river pouring in to our garage when it rains, thanks to Mike! I’ve had 8 men look for those leaks over the years, all claiming it was this or that, blah, blah, blah, egos flying everywhere. All I can say is that I highly recommend Cal Coast Waterproofing. Just realize he only does the waterproofing, you’ll need a contractor or handymen to remove existing materials and haul them away. He also fixed the bathroom light well leaks after decades! It’s time to head up to the roof now… God, I love when it rains.

Mike O’Donnell did a waterproofing job for us on March 2010, and it worked out fine.
We have the same problem leak again, and he came over to look at it. It looks like it may take a while to manifest itself
the rain, but he said to call immediately and he’d come by.
I had another leak and he’s recommended we find an exterior guy to fix it.
So far so good.

These guys were very professional. Certainly will have them back if I need the service again.
