5.0 Robin M. Mc Lean, VA

Stop searching and hoping to find a good waterproofing contractor; you've found the best. Ernesto visited my property, prescribed a solution similar to others I had solicited, but was able to explain every facet of the project in a level of detail that telegraphed authenticity, expertise and real craftmanship. He and his crew completed a 25' under floor ("French") drain, sump pit, pump and discharge system. As is always the case with 60 year old homes, a few surprises were encountered during construction, but Ernesto deftly dealt with each curveball, explaining options clearly to me, answering numerous questions I had and gave his own recommended course of action. The day after installation, the system was put to the test by an all night deluge - which previously would have resulted in me on the floor cleaning up gallons of water penetrating from the floor/foundation. In this instance, the floor remained bone-dry and the elegance of the system shone through. Ernest installed the quietest sump pump I've ever encountered and the discharge solution was truly elegant - not even visible outside - everything concealed within my existing stormwater management system. Ernesto's ability to find and execute on solutions was remarkable. I would hire them again in a heartbeat and recommend them without reservation.

5.0 Barbara G. Reston, VA

Ernesto came out the same day I called to assess my basement water problem and propose a solution. When he and his team started the work, they found more contributing factors and were able to handle them in the original time estimate. They were very professional, clean, thorough, and most of all, patient with explaining my problem and solution.

5.0 Nick M. Centreville, VA

Ernesto and his team team was absolutely fantastic. We had water coming up from our concrete floor in the basement. He came in and explained exactly and clearly what the problem was and how to fix it. There was more water under the floor when he started working than he was expecting, so he recommended that we install a bigger drain. He showed me the water and told me exact cost it would be. Very honest and trustworthy. The final product is really beautiful. You never would have known there was an issue down there. I'm really thrilled with the job he did and I'd HIGHLY recommend Ernesto for your project.

Very reliable and friendly

5.0 Nayda F. Alexandria, VA

We were scammed by another waterproofing corporation that failed the Fairfax County inspection. Ernest Waterproofing came and saved our house from the mess the other company left. At the time of the inspection, the county inspector completed their work. They were on time, clean, and professional. We are grateful we did business with them.

Response from Company:

Thanks Mrs. Neyda , was a pleasure to assist you with the issue in your property. Great New Year for you and your family.

5.0 Marianne L. Arlington, VA

Ernesto was superb in explaining the process and his team was super-prompt and professional in everything they did. They were meticulous in making sure that the problem areas of the basement were covered. I am so glad I had this waterproofing done on the basement of my house, which was built in 1947. The basement is warmer now and doesn't have that constant damp feeling. It was well worth it to get this done before I invested in finishing the area.

5.0 Michael D. Vienna, VA

Ernesto was very professional throughout the process of waterproofing our basement. His pricing was very competitive and his office worked with me to schedule a timely start up and completion time for the work. Ernesto also arranged for another contractor to repair wall board and match paint with existing walls. All together The job was completed on time and the work was first rate. I would hire Ernesto’s firm again without reservation. 5 stars all around.

5.0 Brian F. Springfield, VA

Ernesto was the most prompt and responsive of the companies from whom I solicited offers, offered a very competitive price, and offered an outstanding product.

5.0 Olalekan A. Sterling, VA

Ernest did an awesome job.

3.0 Anthony M. Fairfax, VA

Ernest Waterproofing is knowledgeable about the work to be perform, however, the end result is questionable. This contractor will try to renegotiate after he has provided a contract - unprofessional.
