"Dave from Clifton Contracting/Exterior Waterproofing came out to diagnose a leak in our basement. He came out within 24 hours and quickly identified what was causing the problem (gutters). Although this is a job too small for Clifton Contracting/Exterior Waterproofing, I would not hesitate to contact them down the road if I ever had an issue they would be better suited for. Thanks!"

"Jeff came to give us cost estimate for fixing our basement leaking issue. He was one of most knowledgeable professional I ever meet during my initial move in to new house. He explained why it is leaking and what we can do about it in very detailed logical explanation with clear diagrams to assist my understanding. Jeff said to fix these issues if it still leaks than come back for further assessment. It was great help, and I can really work on source of this problem now. I will never use any other waterproofing company other than All Aspects Waterproofing, LLC."

"We had a basement waterproofing issue. Shopped around a couple of companies. With the best rating on google, and with good reason, Best Buy Waterproofing was our choice. Rob was knowledgeable, diligent, patient and open towards our questions and concerns. Best experience I had with any company rep to date. He came out twice to our place (once the first time to look at the issue, second before he took the work to make sure we all are on the same page.) And then he was there before the work was started to make sure all of us were on the same page. The crew that came out (Darwin, Juan, Raul, Hammie, Chilo) were very careful about their work, respectful, and meticulous. They plastic sealed the work area to prevent dirt, and broom cleaned the area after they were done. Even after the work was done and the transaction was completed, Rob came out to check the work and to make sure it was up to his standard. He olso brought with him the mold treatment up on my request and took care of that as well. Thank you Rob! I highly recommended Best Buy."

"They did an excellent job of waterproofing our foundation, burying downspouts, and replacing a patio to guarantee drainage away from the house. Most of our interaction was with the crew foreman. He spoke good English, showed attention to detail, and did a careful, professional job even when the weather got so hot we found ourselves urging the crew to take more breaks. They were not the cheapest bid, but worth it for the skilled workmanship. This is the second project we have hired them to do, and I would recommend them for any work where drainage is important."

"Lux foundation repair did a wonderful job at my home. I have 4 pipes coming into my home that had deteriorating seals around the pipe. The seals had deteriorated to the point that I had a large plastic box under the pipes so that after every rain I would collect the water that otherwise would have destroyed our finished basement. After small storms, I would collect a couple gallons, after very large storms, I would collect over 8 gallons of water in the box. I spoke to one contractor who suggested excavating the outside of the home. No small task since the pipes enter about 6’ below grade and it would have involved removing several established plants. I was surprised with the estimator from Lux informed me that they could solve the problem from inside the home. I was surprised that the estimator was very confident that he could not only fix the problem, but guarantee that it would fix the problem. The work team arrived on time, quickly did their work and left. When the next storm arrived, I checked the box….no water at all. Was it painless? Yes. Was it worth the money? Yes."

"Excellent. A breeze to schedule with, they texted a photo of the plumber and his name when he was on his way. Arrived on time and successfully unclogged basement drain, then proceeded to replace leaky kitchen faucet. I remodeled homes in a former life, but I did not want to pay for the parts/equipment as the majority of the cost of the work was covered under a home warranty. Therefore, I can't speak to the total cost or value, but I was satisfied by the work completed."

Basement Waterproofing questions, answered by experts

In Manassas, you can address minor basement moisture by running a dehumidifier, clearing downspouts, and checking that soil slopes away from your home’s foundation. For small, hairline cracks, apply hydraulic cement and use waterproofing paint on damp spots. Because Manassas often experiences heavy rainfall and clay soil, persistent leaks, musty odors, or visible mold should prompt a call to a local waterproofing expert.

Helpful?

In Manassas, basement waterproofing may impact your home’s HVAC, plumbing, or electrical systems, especially if these are located in the basement. Sump pump installation often requires electrical upgrades, and interior drainage work may run near plumbing lines. Before starting, discuss your home’s layout with your contractor to ensure all systems—like ductwork or water heaters—remain accessible and undisturbed during the waterproofing process.

Helpful?

In Manassas, basement waterproofing timelines depend on the chosen method and local factors. Interior sealants or crack repairs usually take 1–2 days, while installing an interior drainage system may require 3–5 days. Exterior waterproofing, especially with clay-heavy soil and unpredictable weather, can take 7–14 days. Permit requirements and older home foundations in Manassas may also extend the project during rainy or humid seasons.

Helpful?

In Manassas, the effectiveness of basement waterproofing depends on addressing the area’s high humidity, frequent rainfall, and dense clay soil. Success relies on quality materials, skilled installation, and integrating sump pumps or French drains with existing drainage systems. Regularly cleaning gutters, testing sump pumps, and inspecting for new cracks help maintain protection. Choosing a contractor familiar with Manassas’s unique soil and weather challenges is essential for long-term results.

Helpful?

Basement waterproofing in Manassas can boost your home’s value and attract buyers seeking dry, usable space for storage, offices, or recreation. Given the area’s history of moisture issues due to clay soil and seasonal storms, buyers appreciate documented waterproofing and transferable warranties. This investment can also help with insurance eligibility and loan approvals, making your home stand out in the Manassas real estate market.
