"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!"

"We are the 2nd owners of a 15 year old home. Don't know why the original owner/builder did not put a sump pump in the basement, as it would have been a cheaper option in the end. If you are building a new home with a basement, put a sump pump in, don't scrimp on what is a very valuable insurance policy. After looking at a handful of other companies to retrofit a sump pump in our cellar, we picked All Aspects Waterproofing, LLC. They did a great job! Very high quality work, and outstanding service. They did a great job! We enthusiastically recommend All Aspects Waterproofing to any homeowner!"

"We moved into new house and quickly found out the basement had major water issues due to years of neglect (including a clogged and poorly installed English drain from years ago, and a sump pump that while it worked, never pumped water.). Given the investment we made in buying the house, we wanted to make sure we left no doubt in our mind that we were fixing it for the long haul so we could use the basement without worry of mold/mildew for our kids. We had NV Waterproofing install perimeter wide gutter guards, and a new sump pump system and drainage pipes. As soon as the work was done we got rain, and for the first time in the 4 months since we have lived here I saw the water that otherwise would be in our basement actually in the rear of our backyard by the discharge pipe. We have had a few more rains and even one snow and there is nothing better to look at then when I see the water that is coming out of the discharge pipe that I know otherwise would be pooling in my basement and cynderblocks walls, and how that was the case for many years before we moved in. Also, the team that did the work was extremely professional. We have 3 kids and pets and the team was extremely courteous. We tried to stay out of their way during the week they were doing the work, however there were times when we couldn't and the team was extremely courteous and professional. The team lead did an amazing job of explaining to me the work he was going to do, showing me updates, and then afterwards explaining in detail what was done, why it was done, and things for me to look for for in the future. I would highly recommend NV Waterproofing to others based on my experience with them. They did high quality work and were extremely professional."

"Exceeded my expectation with waterproofing my entire basement + window wells. These guys are the real deal! I worked with Rob and I was educated and all my concerns were addressed. They do it right by you, the contract missed a window well and they were able to addressed that without having to go through a whole new quote/contract. Helped move some furniture around and left the place clean."

"I highly recommend DES! I arranged a consultation after a home inspection report indicated that there was moisture in our basement walls. I was worried that costly mitigation efforts would be required. A friend who had previously used DES for a basement water problem highly recommend them, telling us that they were an honest company that only does what is necessary to solve a problem. Happily, Mark Fine from DES inspected both our basement and our exterior grounds and reported that there was no indication of cracks in the foundation or water intrusion, and that no work needed to be done. It is so refreshing to have a company that doesn't try to sell expensive services when they are not necessary!"

"I hired Alex three years ago to stop the water from coming into our Florida room. After going threw four other contractors he was the only one that took care of the problem. Now we hired him again 7/19/18 to take care of the water coming into our basement. He sent out Tyrik, Corey, Nathan, Casey J;mony, Cody and Joe. They were very professional and and kept informing my husband of the progress they were making. At the end Tyrik explained everything they did and told us if we are not happy with any of the work they will fix it right now."

"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, 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?

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, 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?

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.
