By Sam
The half-completed job by the first crew is really the only problem we had, and even though you did rectify it quickly, it was disappointing that it happened at all. But good job responding to the problem on the supervisory level and fixing it quickly.
By Bobby
Only negative comment is that I was told we could get a 6-month interest free loan to pay the balance. Never received information as to process--bank, paperwork, etc. Therefore, we had to pay the balance upon finish of job.

My basement is dry and the atmosphere in the rest of the house seems must more pleasant and warmer on the coolest of days before actually turning on the heat. Thanks for a job well done.
By Thomas
This company is owned by a very dear friend of mine. I know him and his family personally. I have highest regard for him, his integrity, work ethic, generosity and his care. This company did an excellent service for me and my family. They were very clean and efficient; very quick, and they stand behind there work with a guarantee. I give them the highest review.
By Scott
The only complaint that I have about the work done is that when it came time to return my hot water tank back to its location near the wall of the basement I found that the installers had placed the port hole for the system right where I needed to put my hot water tank in order to reconnect it. Luckily I can still gain access to the port hole and didn't end up having to re-route my piping but it is semi-covered by the tank which is a bit of a hassle. Other than that I was very happy to see that they were able to install the system without having to cut away my finished walls.
By Teija
The whole process was quick andprofessional.I have enjoyed a dry basement for almost a year now. Thank you!

By Roula
Mike was very friendly and explained everything he was doing and gave additional suggestions for things i could do around the property unrelated to the basement system put in.
By Lynn
I would like to take this time to let you know how impressed I was with Mike Dyer. He was prompt, knowledgeable and pleasant. He came to my home after the team installed your system. There were several items that needed to be addressed/changed/modified. Mike was able to do all of these. I am more confident about the system now. He explained what he did and why. He was very thorough. I would recommend him.
By Phyllis
By comparison to other companies, there was no hard sale which I appreciated. The salesperson from another company actually expressed anger when I said I needed 3 days to think about it, but the salesperson from Basement Systems even suggested himself I could take some time to think about it. The crew that came out seemed very knowledgeable with the lead guy explaining things in detail. I felt confident with that he was being truthful. We will see when we have a big rain.
By Robert
I could not be more satisfied with Base Systems. They came on time and were extremely courtious and polite. the work was done vey well and they cleaned up really did not leave a mess. All in all Willie Ransomand his crew did an excellent job .

By Lynda
Absolutely. Wish I had known about you years ago
By Greg
Basement Systems customer service is exceptional. They kept their appointment even tho there was a snow storm the previous night. The installers got stuck in the snow on the way to my home, they were towed out and still came to do the job and didn't leave until it was done.
By Beulah
Beulah Rimel is my aunt. I am filling this out for her. I went into the crawl space after a big rain and the updated system was helping a lot to evaporate the water that seeps in. My aunt's electric bill has gone up, but that was the \"trade-off\": Less water vs. more energy to get less water. (Deborah Harrison)

Jeff did a nice presentation with his recommendations and our budget. He responded to all emails and helped us to get the cost down.Jorge and his crew did an excellent job from start to finish. Jorge checked with us every day to ensure we were satisfied and to answer any questions.

I would like to personally thank you for your professionalism, understanding, and providing quality repair service outside of your normal servicing areas. In addition, the Service Technician (Dakota) who worked on the sump pump system was exceptional and should be commended for his skillful workmanship

The crew was very knowledgeable, positive, punctual, tidy, and hardworking They took the time to explain the process and it made sense. I expected it would take much longer than it actually did. So, it was a great overall experience, and, best of all, no more musty smell! They did a great job.

Gary arrived exactly on time. He is wonderful individual. I didn't feel any pressure with what was described to me for my basement. We discussed all of my option. I was happy with my decision during and after I signed the proper papers. My install was scheduled that very day and in less than 2 weeks I have a new basement.  My sump pump was installed without too much interruption to my family life. My basement looks amazing. The waterproofing material and chair rail looks great. It hadn't rained much since the installation, but I am confident that there will be no more problems in my basement with leaking.

From start to finish, I received stellar customer service from everyone I encountered when inquiring information about my crawl space...from every person who answered the telephones and my accompanying questions, to the person assessing the situation to the actual team completing the job. This company employs PROFESSIONALS!!!!Thankfully, they were able to schedule an appointment quickly. After assessing the situation, Jeff recommended encapsulation of the crawl space, providing multiple views via supporting photographs to further explain their services and the process.I then contacted Amanda, who performed a miracle and scheduled the encapsulation quickly in less than 2 weeks, April 8, 2022 to be exact.Throughout the process, they kept me informed via telephone calls, emails, and text messages. Due to their sustained excellence and quality customer service, I was fully prepared and had no doubt the tasks would be completed efficiently.Bernie, the foreman, called me April 8 to provide his estimated time of arrival. I met him at my house along with Fernando and Edgar around 9:15 a.m. All three men were pleasant and I felt comfortable with the information and explanations they provided.I left my house while they performed the tasks at hand. Since the house is vacant and the chemicals, etc. they were using can be harsh, I left them to their own devices. Bernie telephoned me around 1:40 p.m. to say they were finished, cleaning up, which was much sooner than their earlier estimated completion time of 6 p.m.When I returned, Bernie provided explanations of the work provided as well as photos of their work and a tour of the exterior work completed. I am beyond pleased with the service I received and HIGHLY RECOMMEND them to my friends, family, and enemies too. Everyone should support this company, as they are credits to their profession.Karrie, Amanda, Ashley, Tina, Jeff, Bernie, Edgar, and Fernando did phenomenal work and I'm glad they were assigned to handling this job! Thank you for every kindness you extended and all our professional encounters.

My experience with them was very good. They were very professional. They were very knowledgeable about what was happening in my house and about the issue that we were having. They didn't try to get us to spend needless amount on items that were not going to do anything different. We had someone come earlier and they were charging arm and leg for the job. But the gentleman from Basement Systems came and checked everything out.He had a computer with him and he pulled out everything and explained all the stuff for about two and half hours. He seemed to be pretty relaxed. I thought that it was expensive but it was fine for what we got.
Lisa S.

I like working with Dave, he is very responsive to my concerns. I dealt with him alot on the phone. Because they are such a good company, they are giving me great warranties. I like the workmanship of the job so far. The technician that came out found out that the motor in my sump pump was not working, he is very thorough. They would always keep me up to date on what was going on, when they would be arriving, and any new information regarding my service.

Jessup, MD
After a long night of manually pumping water out after a power outage rendered our sump pump useless, we hired this company to install a new sump pump pit with a waterproof housing and install a second pump and a battery back up. This was in 2012 and we have never had another sleepless night manually pumping again. Jorge, the installer completed the job quickly and professionally. Since then, they have been back to service and maintenance our entire sump pump system and Jorge always comes. I appreciate that they send the person who installed the system because he knows what to look for. They have honored their warranty and we were able to transfer the remaining warranty to a new buyer after we recently sold the home.

    This homeowner in Westminster, MD reported their old sump pump was no longer working properly, so they called us for a solution. We knew since their sump pump was old, they would benefit from installing our TripleSafe Sump Pump System. This system is lined with three pumps that will effectively pump water out of the basement and also has a backup battery that will kick in if the power goes out. We also installed our SaniDry Dehumidifier to circulate the air in the basement. Thanks to our System Design Specialist Jeff, and our foreman Bernie, the homeowners' peace of mind was restored!

    Customer had a standard basement window that was cracked and allowing water to get into the finished basement, the customer reached out to us because they wanted to update the standard window to an Egress with hopes that it would help stop the water from getting into the basement. 

    For this basement project we installed an Egress Window a Wellduct, Waterguard and a SuperSump Pump. The well duct will direct any water getting in through the window well, down the Waterguard which will then flow to the SuperSump to be pumped out of the basement.
