Top Reviewed Foundation Companies in Ashburn

Everything went fantastic, and the crew was great! I was so glad to have waterproofing done on the outside so that no more water would be coming in -- and to have the driveway/sidewalk work done at the same time. Very few companies could do both jobs, and many companies wanted me to do an interior sump pump instead. I've had plenty of neighbors stop by to tell me how great it looks!

I was very happy with the work done. It wasn't cheap, but it's very good work. I now have a dry crawl space and peace of mind that my foundation will last for many years to come and I'm not constantly pumping out my crawl space every time it rains. They installed additional supports, poured a new footer, created an exterior entry into the crawl space, installed a sump pump and a dehumidifier as well as lining the interior brick with a waterproofing compound as well as installing drainage interior to the house. They even reinforced all the joists, both at the lateral and perpendicular, and installed lots of insulation. I can actually sleep well at night, for the first time in 9 months.

Overall, services were performed well. The engineer sold us on the sump pump with their company versus other pump/drain types and versus excavation based on their quality and warranty. The main issue we had was responsiveness. After the pump install, I was informed the discharge pipe would be installed that saturday. They didn't show up and ended up completing the job 2 weeks after the pump install. The drywall re-install was completed ~ 1 week after pump install. However, it seems the general install quality was good. We shall see what happens when we have another downpour! Another issue we're running into is that we now need another contractor to reinstall the carpet, prep/paint the walls, and restain the baseboards. This isn't an issue with Value Dry; it's the expensiveness of fixing up everything to make it look the way it did before. I think prospective customers should understand there is a lot of work that needs to be done after Value Dry completes their job to make the rooms look like they originally did.

B-Dry extended the drain system in our basement including installing new drains in 2 window wells. This involved removing dry wall, floor covering and cement, installing the drain approx. 10'x 2' , replacing the concrete floor and connecting all drains together. They cleaned and repaired a third window well drain that they had installed in the 90's. They enlarged the sump pump well and provided and installed a new, more powerful pump and a back up battery system. They covered everything so that the concrete dust did not get on any of our belongings. They were prompt and professional and accommodated our schedule when we needed a delay. During the heavy rains of the past few days we remained dry as a bone in areas of our home that have been flooded in the past. We have learned to check our sump pump periodically to make sure it functions properly.

I was very happy with the experience. They installed a drain system around my basement with a sump pump and installed a waterproof barrier on the walls. They also sealed a crack with epoxy as well. I am so happy not to have to worry about this problem anymore! All in all it was an easy going and convenient experience.

Very pleased. Had to move all my shrubs to seal outside and install pump. Replanted everything beautifully and it all survived.

The work went well. Manning, Alex, and Ro did a very excellent job on installing my sump pump system. Their work was excellent and professional and we are very satisfied with everything they did.

Excellent, everyone was happy! Most impressive was the finish work. The sod was healthy and plush and the details down to the small gravel rocks in between the fence and railroad ties installed evenly. On to the next project, thank you!

I would use Premium Drainage & Erosion Solutions in a heartbeat. One side of my yard, which is a low grade, was waterlogged, creating a lot of standing water. Premium Drainage located all of the standing water and recommended a great solution.

from a portion Initial contract was for S&I up to 4-6" bubler pots in conjunction with install of buried discharge line,supply and install bentonite injection ,supply and install 13ft. channel drain etc.Some water still leaking after very heavy storms.total cost $11,700.Next Supply and install custom catch basin in ceilingw/drain system.Demo drywall and framing,a one way move,plumb both discharges into sanitary line. Cost $15000.This job took about 5 days of substantial work,was it necessary ,I do not know.Next a drain pipe froming a small portion of a flat roof was found to be the cause for most of if not all the water coming into the house ,that was repaired well ,by only one very competent worker in two full days at a cost of $5900.As I comment I was add the work quality was excellent however the cost was an outrage.

Two sets of piers (one on front side and other on the side) were installed 4 months a part. Both installations went well. One side of the house was 1 3/4" lower than the other. JES was able lift that side 1" to reduce asymmetry. Jaime and DeShawn were incredibly professional and detailed in their explanations when we had questions.

Foreman, co-foreman and installer were very efficient, arrived promptly for three days, were very knowledgeable. Answered all my questions and concerns

Perfectly. Levelift was easy to work with and very accommodating to my crazy schedule for a start date. In the end it turned out perfectly because even the weather agreed last week after a brutal winter. Monday morning the crew showed up as agreed and showed me the plan. The immediately began working on the outside part of the job, pulling out necessary shrubs and buses, digging holes for pier installation. The first day they installed 2 or 3 piers. Second day a crew came to take out part of the living room floor (this is another company I hired to do the inside finishing work once all the foundation work was completed) so that the fireplace and chimney could be stabilized properly. Later in the day the foundation crew began digging inside that hole. Third day they drilled out two holes in another adjoining room to install piers (that part of the house in built on a slab, remainder of house has crawlspace) as well as another hole under the back patio for final pier. They also began installing piers inside as well as completing pier installation on outside front of house. Fourth day they completed all pier installation and began refiilling holes with dirt, compacting each one tightly. Fifth day they poured concrete back over the two side room holes, replanted shrubs they had removed, and put topsoil over outside work area (could have chosen topsoil or mulch). Then they cleaned up everything. It looked better than when they started. The second crew from another company came in and began installing the new joists under living room floor and closing up the hole for the weekend. Levelift did a great job. Before deciding on a contractor I had also hired an individual structural engineer to evaluate the situation. The proposal Levelift presented was in sync with that report. I had also had two other companies bid on the job, but Levelift turned out to be the best fit. And the job they did was excellent.

JES installed a sump pump and french drain encapsulated system in my basement crawlspace to correct repeated flooding in my basement. I asked them to come back out a week after installation because heavy rain again flooded my basement. JES figured out what was causing the problem and completely reworked the system and eliminated the flooding. There was no additional charge at all; they stood by their work and were not satisfied until I was satisfied! I highly recommend them.

The assessment went great! The engineer was very professional and inspected my home and designed drawings for permitting. They then cut open my foundation wall and installed a large staircase and french doors at the bottom. All the work was exceptional quality and they even put grass seed down on the disturbed areas of my lawn. I show everyone that comes over our house! A++!!!

We had an engineering inspection performed and they determined we should seal the cracks with epoxy and install a drain and pump. They gave me a lifetime warranty on the repairs and the drain system so I am happy as can be!

Highly professional. The job went very well, they were fast, did a good job and thoroughly cleaned up the job site after completing the work.

My experience with CENTERSCAPE went exceptionally well!!! A little history: a few years ago, I had a very expansive patio installed in my backyard by (another company). I was so disappointed with that project, that I finally dismissed the contractor from the job and demanded he not return. He cut corners on many things and installed other things incorrectly. Very unprofessional. I WAS NOT looking forward to having another encounter with a hardscaping company. I needed, however, drainage holes installed, since the initial company installed NONE seven years ago!!! In walks Frank of Centerscape into my life!!! Not only was he professional and extremely knowledgeable, he was on time, cleaned up after the job, a good conversationalist, and despite running into some unforeseen problems that the initial company created, he stayed true to his price quote from a few days prior. Without a doubt, I will use CENTERSCAPE for ANY AND ALL other masonry/paver/hardscape projects in the future. Frank, I can't thank you enough. You're MY GUY, and have single-handedly restored my faith in your industry!!! BRING ON THE RAIN!!!

The inspector found the source of the moisture in the wall to be a tiny leak dipping from the connector in the sewer pipe. Then he told me that 3 small puddles of water that I had found weeks earlier on the floor in the middle of the basement were NOT caused by seepage. Another company was not sure, but did not have the experience to decide for sure that it was not a seepage problem, since there was no buckling of the laminate flooring. The workmen were prompt and efficient. The did a good, neat job.

Matt is a very kind person whose team was very nice to work with. They were respectful, clean, trustworthy, and made sure they listen to our wishes and concerns. They worked very hard so we could move in before Christmas. The projects after that were slower but we had added several projects in the process and overall they got everything accomplished in about 4 months. Matt always reacted on time to e-mails and calls. Sometimes is was hard to reach his team to find out when they would be coming and what they would work on but one call to Matt and he made sure we got a reply. Green products and limited chemicals were very important to us and his team not only respected that but also collaborated with us which products to use. We had a major water problem in the basement and they were able to fix it with additional drains, a sump pump and a successful concepts to redirect the water from the house. We have had a lot of rain so far and the basement has been dry, yeah! The built-in closets were done by a different team and took more time than we expected. They didn't turn out the way we wanted but Matt worked with us on that, reduced the price and had the team do some changes. We heard many horror stories about other contractors from friends so we were worried starting this big project. Overall we had a very good experience with Willis Builder. The majority of projects were done very nicely and to our satisfaction and Matt was willing to work with us on the couple things we were not so satisfied with. We also know, should there be anything in the future, Matt will not hesitate to come and fix it. We would work with him and his team anytime again.
