"Jim and Jordan were both professional and honest. They worked with us on installing an interior french/foundation drain around half of our basement into an existing, outside sump pump and did not try to oversell us on adding a second sump pump (as other companies did). Their crew were all polite, efficient and hard workers and left the area clean and finished off in a professional manner. For years, every time there was sustained rain we would have water seeping into our basement. Since their installation, we have had sustained rain a number of times and the foundation drain has worked very well. No more water in the basement. I would highly recommend them."

"Will & Frank were great. They dug up an area from the outside and installed a French drain that went all the way to my backyard fence. No leak with today?s rain! Works splendidly!"

"It was great. We had demolition on day one - removing old wall paneling and knocking out part of an interior wall. The crew was fast! Second day the first crew started in the morning with removing the concrete around the edges and dropping in the new drain and then sealing the walls. A second crew dropped in in the afternoon to help with the jacks in the crawlspace. These guys worked very hard and fast! Love the look of the new space. No more musty smells and everything is white and fresh and ready for a real remodel."

"I was very impressed with the finished product. I had this company just pour and finish my 30 x 60 slab. I put dirt in, leveled it and formed it, and put wire in middle and re-bar around the sides. I was worried they didn't have enough help, just 3 people. They worked well together and knew what to do. The surface was very smooth I have never seen concrete finished too smooth. I will use them again."

"Overall, it was a good experience. AAA put down a vapor barrier and installed a Santa Fe dehumidifier with sump pump. The result is that we can now use the stand-up basement/crawlspace to store things under the house without ruining them. This is the part that you need to know. The installation was not without problems. First, they broke an A/C drain pipe, second, they cut a sprinkler controller wire while running a PVC pipe. Here's my take, accidents happen but how does the business respond to these issues? Well, Donna was very quick to send her team out to correct the problems and they even paid for the damage to the sprinkler system. To me, that's top notch customer service. Any business can make a mistake, but how they handle it is the mark of a good company. Every time I lift the roll door and go into the basement now, I'm amazed at how cool and fresh the air is down there. No more mildew and no more smell."

"Awesome experience. Purchased home with open crawl space that was deteriorated with hanging insulation, and breeding ground for rodents and waste. Researched crawl space options and interviewed several companies to compare. Greg was honest, informative and provided an option that encapsulated the raised crawl space, complete with dehumidifier and thick vapor barrier. He promised to come by annually to check and make any necessary adjustments and stood by his word - we had the project completed in 2015 and he came back in 2016 adding some sealer to small gaps that occured and will be scheduled him again to return soon for 2017 service. VERY happy we completed - the house smells much better (they disinfected underneath and spent time ensuring joists were clean), air quality and comfort level is greater and greater peace of mind with rodent exclusion. Would HIGHLY recommend Greg and his crew"

"Eddie came out and gave an estimate. He was professional and personable and set a date and time for the following week to do the job. Due to other (larger) work obligations, Eddie wasn't able to keep the appointment. However, he sent his son, who was just as professional and personable! The job was completed without any issues. I was impressed (and grateful) that Eddie didn't put me on the back burner and reschedule because it was such a small job. This malady in my floor was preventing me from installing hardwood flooring so I am very happy it is done!

"It is the best choice for anyone needing to put in new heating and air. When my units were installed it was very cold and raining that day, They were so professional they covered all my floors from downstairs to upstairs to keep the floors safe. There was a crew working under the house putting in the downstairs unit in the craw space and another crew upstairs putting that unit in the attack. Their warranty program is the best and they always service both my unit every six months. It really is the best decision we ever made going with Ragsdale ."

"I commend Foundations Solutions 360 for their integrity, work ethic, and commitment to customer satisfaction. ony and Charles were at my home today. They were patient, professional knowledgeable, and creative in resolving an issue caused by the location of my gutters. They took time to explain the planned work; and, before beginning, clearly explained the process and even set up a configuration to enhance my understanding and to ensure satisfaction. I was impressed with their knowledge and communication. Again, I would like to emphasize their integrity and work ethic., Not being knowledgeable about foundation work and related issues, I must trust the knowledge, honesty, and commitment to excellence of those professionals who work on my home. I am fortunate to have chosen Foundations Solutions 360 and am especially grateful for Tonny and Charles and the work they completed today. Their knowledge and attention to detail are impressive and reassuring, and I am very grateful. The crew who initially worked on my home were also industrious and efficient and equally deserve commendation. Kudos, too, for Joek, the person who leads the Foundations Solutions 360 team. Despite his busy schedule, he always took tame to address my needs. He patiently and carefully addresses customers' questions and concerns and provides clear explanations. Finally, also worthy of recognition are Linda and Liz, the secretaries who receive customer calls. They promptly and cheerfully answer calls and efficiently addressc customers' needs. Waiting on hold is not a problem for Foundations Solutions 360 customers. Foundations Solutions 360 reflects the same commitment and integrity to homeowners with foundation problems as their commitment and integrity to serving our country, and I am grateful for their service."

Foundation Drain Installation FAQs, answered by experts

Some questions you should ask before hiring a plumber or drainage installation company include:

  • Are you licensed and insured?

  • Do you have any customer testimonials I can read?

  • How do you handle unforeseen challenges that occur during the job?

  • Is your fee a flat rate or hourly?

  • Do you do the work, or do you have subcontractors?

  • Is everyone who does the work licensed and qualified plumbers?

  • Is cleanup included in the quote?

  • Do you offer a warranty or guarantee on your work?

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.

In most cases, standard homeowners insurance policies do not cover damage from a sump pump failure or overflow. Coverage for water damage is often limited to sudden, unexpected events like a burst pipe that was not caused by negligence. To be covered for sump pump issues, you will likely need to purchase a specific rider, endorsement, or additional water backup insurance. If your insurer offers this type of coverage, they may require proof that your sump pump is regularly maintained.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.
