Basement Wall Sealing Richmond VA Waterproof Your Basement With Our Wall Sealing Services

Darryl and his crew did an outstanding job encapsulating our crawlspace - I highly recommend Kefficient!

We used Kefficient for mold remediation and basement crawl space encapsulation. They are one of the few companies that we have used for house projects that consistently communicated about the progress of job (we are so grateful for this). Super professional, thorough and tidy.

We had a perfect storm recently with a failing sump pump in our crawlspace, improper previous setup, and a baby about be born. After reaching out to Kefficient, we were linked with Brad who has been our personal champion. He made us multiple quotes for our project to set up the crawlspace properly and fully encapsulate the space. Unfortunately with the baby coming, we did not have the budget for a full encapsulation project and ended up walking away with no solution. Brad called us back the following day with a proposal to properly set up a new sump pump with a robust drainage solution to address our immediate need. This new proposal was well within our budget, especially with the "same as cash" funding option and it has brought our family peace of mind moving forward in this new adventure. The sump works perfectly, the drainage ditch and new discharge line are innovative and incredible, and the quoted five day project was finished in two days!!! We have a lifetime guarantee on the drainage system and we have the ability to continue the encapsulation project at a later time. Look no further for your waterproofing needs, these guys are the top of the industry and worth every penny. I cannot recommend them enough and if you want a stress free experience then make sure to ask for Brad!

Kefficient did a great job on work needed in crawl space to secure flooring with a new steel beam and boards. Friendly staff and systemized teams per stage in work done. Easy to get in touch with if had questions along the way.

Fantastic Comoany to work with. On time, quick quality work that combo is not easy to find. My crawl doze looks like a new construction m. Thanks Mark and the whole team!

Brad came to our house for an inspection and estimate for crawl space moisture remediation. I was quite pleased with his thoroughness and careful explanation of what was needed. He was quite pleasant to deal with, and Kefficient's estimated price was far lower than the "big-name" competition for the same services. Once the approval for a home improvement permit was received at the beginning of October 2023, Kefficient began working on our crawl space remediation the very next Monday. Kefficent's owner, Mark Keffer, was on site nearly every workday to supervise the crew, update us on progress, and answer any questions. On the days he wasn't here in person, he spoke to us on the phone. The primary work crew of Ernesto, Alexander, and Delmar were professional, courteous, and extremely hard-working. They were assisted by several others on a couple of the days, including a Saturday when they all worked until 6 pm. It took a total of 7 days to complete the project, consisting of a proper drainage system with gravel trenches, pipes, 2 sump pumps, and a drain pipe exiting the house. Also the crawl space was completely encapsulated and a dehumidifier was installed, complete with duct work and vents into the first floor of our house. We were very happy with the quality of the work -- our crawl space was totally transformed! Last, considering all the work that was done, the total price of the project was very reasonable.

Brad came to my house and told me my job was really too small and he didn’t want to take my money. He was upfront and honest about everything. He told me what product to get and what to do exactly. It’s hard to find a good honest company these days. Thank you Brad Conner!

I had a great experience with Keffecient. Daniel was wonderful explaining the process and showing me pictures and videos of what actually would be happening. He took the time to make sure all my questions were answered. Price was very reasonable. The men showed up when they said they would to complete the job. Very respectful of my property. Left the area in great shape. Very professional. Daniel followed up with me after the job was completed sending me pictures of the work they had done. I highly recommend this company.

Recent experience was excellent. Communication from the sales office allowed me to get the project started ahead of initial schedule. Team that did the crawl space work was on time each day and worked non-stop to get the project completed. I have nothing but positive comments on the work and the results

Kefficient did an excellent job at the best price. And the get-it-done mentality made it happen. Here are some suggestions. We had a contract in May 2023 but the contract was not fulfilled until the end of Sept 2023. Partly my vacation and partly their problem. Kefficient kept saying that VA couldn't give us the Permit until later. I complained and the Permit came the next day. They sent us the bill before they finished the task. (They finished it very well.) When they finished the task, dust was every where in the basement. We complained. They came the next day and REALLY cleaned it and it was done by a very cordial man and asst. Last they have a machine in one corner and I'm not sure of the purpose. Probably my problem but info would have been helpful And the owner was the nicest and came to visit every day except the last. All of this said, I loved their work.
