"It was a pleasure working with AA Action Waterproofing. We had issues with water seeping through our floor after rain and had no idea where it was coming from or why. Then we saw mold! We needed new sump pump and drainage and 1 wall crack addressed. From the estimate to job completion AA Action Waterproofing was thorough at explaining our issue, the cause, and answered any questions we had. The team was punctual, clean, and did not remove anything other than what was needed (flooring, drywall, etc.). They also did a walk through with us and explained all the work done before they left! Since the work was done, it has rained, and our basement is dry! For the cost, it was great value for the quality of work. Highly recommended!"

"As someone who has dreaded going to the basement for 20 years, I am now incredibly thrilled with how dry and clean the space has become thanks to the excellent work by Gary, Benjamin, and Edgar at Basement Systems USA in Elkton, MD. These men were polite, respectful of everyone's time, left the place cleaner than they found it, and were thorough! Each step was carefully explained to me and confirmed throughout the process. There are no more ugly, mold-stained walls or beams; water runoff outside the house was diverted; and a new, size-appropriate sump pump and dehumidifier were successfully installed. I couldn't be more pleased with the professionalism of this team (and they finished sooner than quoted)! Thank you Basement Systems USA and especially to Gary, Benjamin, and Edgar!"

"I was having some issues with water coming into the basement through the foundation and walls during rainy weather. Not flooding, or even shop vac-able volumes, just enough to be annoying and require mopping. Dominic and his crew were here today to install an under-floor drainage system and a new sump pump. I was dreading the demo (I have a concrete floor) and the mess involved, but these guys came prepared for everything! They used dust abatement measures to protect all my basement-stored items, and they removed and hauled all the debris away when finished with the excavation. What really impressed me was the concrete restoration upon completion. I've previously had a sewer line replaced through the basement floor, and the contractor really "botched" the floor repair. I can't describe how different this experience was! The concrete installed today is immaculate! Dominic takes pride in his work and with good reason! The new concrete is perfect! I am thrilled!"

"Our foundation was seriously compromised due to water intrusion. Steve responded quickly and gave us an estimate at a great price. He was knowledgeable and informative. Dan and his team repaired our foundation, installed a drainage system and pump, as well as a vapor barrier. Our basement has been dry and free of mold since. The project was completed in a matter of days. I couldn’t believe how quickly they worked. I recommend the gurus to everyone who needs basement repairs. Thank you again!!!"

"We have been working with Affordable for a couple of years now. To put it lightly, we have the basement from hell. When they arrived, we had some water in the basement and they quoted us based on their normal pricing. Once the concrete came up, we couldn't believe what we were dealing with. It is a constant flow of water that required two sump pits and an insane amount of work to install our drainage system. Every time they tried to dig a pit it would backfill with sand and water- they had to dig this up painstakingly- foot by foot. We thought for sure we were in for additional costs, but they stuck by the original estimate. Since then, any time we have had an issue or a question, they are quick to answer. Poor Kelly and Bobby probably recognize our number on the caller ID but whenever we make a call or send an email, we always get a response- usually with a visit on the same day. We highly recommend this company for their honesty, customer service, and quality work."

"My sup pump failed and they came out the same day. They replaced the sump pump and spent hours getting the water up. It was great they could get this all taken care of on a Saturday. They are just great. Reasonable prices and they are always good."

"I had a great experience with Best Buy waterproofing. I contacted them for inspection due to water rising underneath my tile in the basement. They responded very quickly and had someone out for the inspection a day later. Ed completed my inspection and was very informative and communicative throughout the whole process. He didnâ t try to scare me into getting any services and was very patient with me. Any questions I had he was on it and available. When I made my final decision it was quick and a painless process. The crew cleaned up well and walked me through the work they had done. They installed a new drain and sump pump. Might I add they made my installation very esthetic by placing the line in the wall to hide the pipes when the dry wall is replaced. I will definitely recommend to friends and family!"

"They installed our sump pump system with backup battering very efficiently and professional and in less than one day. After discussions on the correct equipment, they provided additional effort to be sure the wi-fi backup equipment was installed and was working efficiently. Any questions on installation and operation I had were answered on-the-spot and with ease. System seems great and I now have peace of mind during a bad storm or if the power should go out. I would recommend them to anyone."
