Exterior Waterproofing Experts, A Division of Clifton Contracting

Highly recommended. We spoke with over 10 contractors to get an egress window installation in our townhome but none matched the professionalism and service offered by Clifton Contracting. The process was explained upfront, the quote and contract were clear, and the team was professional and delivered excellent quality. What seemed like a complicated job to us (and the other contractors) was a straight-forward project for this team, and it was the best value overall to include quality materials. In fact, the end cost was less than half of what one contracting team wanted. All in all, these are the specialists you want if you're adding a basement bedroom, egress window, or similar.

My basement had a moisture problem in one corner. I had a number of contractors look at it. Most proposed trying to fix it from inside by installing a french drain and one or more sump pumps, and quoted $10 to $18 K. They seemed reluctant to address what was causing the problem, a crack in the foundation. Evan from Clifton took what I thought was a more logical approach, i.e. excavating around the corner and patching the crack from outside. His estimate was so much lower than the others that I felt certain he had left something out. That was not the case, so I signed the contract. His crew showed up on time and immediately began excavating all the way to the footing of the foundation. They were very courteous and answered all my questions. Soon the large foundation crack became vi

We had a small leak that grew into a big problem but Kenny handled it. The crew worked late to finish the same day and the results are solid. I recommend them to anyone in the Fairfax area who values honest work.

Evan and his crew came out to even out the grade in our front and back yard. Evan gave me a great price for the work. They removed existing plants, added dirt, fixed the grade, added plants, and added mulch. His crew was on time and hard working. Highly recommend!

I chose Clifton to do our BMP - rain garden and permeable paver driveway - because of the experience I had with them building my house years ago. Chris is a great guy, explains things clearly, and has very competent workers on staff to do the job. They were very creative - using some of their own supplies to make the driveway look better than the plans!
