21st Century Waterproofing

They are very neat and clean! I didnâ t have to clean up after them at all! Thatâ s a plus!

21st Century Waterproofing is the best waterproofing company in the LA area. William Kleeberg knows his stuff and prices his work fairly. Looked all over for a waterproofing company, checked out many companies and found 21st Century Waterproofing to be No. 1

I would highly recommend Bill. He correctly water proofed my foundation. He and his crew are true professionals as well.

Anyone who has waterproofing needs should hire Bill and his team. They are fantastic. I am the President of our HOA ( 5 townhome building) and a resident in one of the 5 units. The building had a number of areas in our underground common area and one resident's garage in particular where water was draining from outside of the foundation of the building. There were no less than 4 separate areas where water was entering the interior of the building. Of all the contractors we interviewed for the job, Bill was the most honest, practical, thoughtful and analytical in his approach to the job. He was more like a surgeon carefully dissecting the problem and then fixing the issues, one a time rather than what most of the other contractors wanted to do, which was tear up the east side of the building and "we'll then see what the problem is." He and his team showed up everyday they said they would - on time. They worked hard and cleaned up their work area every time they were there. He tested his work (flooding areas and letting the water sit for 48+ hours) to make sure he had done the job right and completely. He explained what he was going to do and then he did it. I highly, highly recommend 21st Century Waterproofing. One of the best contractors I have ever hired - for ANY JOB - in my 30+ years of managing properties.

Bill and his crew were extremely professional and helped assess the issue and fix my waterproofing problems quickly. Highly recommend.

Recently did a full waterproofing treatment for a new-construction basement. Called me back following my initial inquiry on a Sunday. Fit me into his busy schedule and expedited our installation to keep our construction on track. Would definitely recommend them.

They help me with all my commercial properties. They do an excellent job and warranty their work. They are an excellent company
