They were quick to reply and take action. Did a great job. I would hire them again in a heartbeat.

I had a horrible basement flood in December 2018. I had had many such floods and I decided that I…read morefinally had to do something about this. I called a number of companies to seek an appointment for an evaluation of my situation and an estimate on how much it would cost to fix it. Harris promptly got back to me (only one other company returned my call) and we made an appointment. The estimator soon came out and evaluated my basement troubles. Developing an estimate took a few days - longer than expected - because he wanted to share the unique aspects of the problem with the company's owner, Tim, so they could best figure out the ideal solutions. I was happy to wait a few days for them to have more time to really think about the problem and what would be best: better than some "one size fits all" fix that wouldn't fix my basement problems. They determined what they thought would solve the problems, and that that it would be simpler (and more cost effective) than they originally thought. I hired them (I eventually had one estimate from another company - they came out after a few months; their estimate was much higher, $-wise, and they wouldn't be able to start work for a few months anyway). While there was a bit of a wait, given their other jobs, I got the work done quickly. Their employees were professional, and friendly, and really cared about doing great work. In the course of the job, they realized that the original plan wouldn't work out in one way, and again decided on a cheaper, more "conservative" respond to the problem which saved me money. All and all, I think Tim Harris and his crew really were just interested in solving my problems in a manner that would be effective and reliable, and at a fair price. Oh, my basement used to be a horribly disgusting place - dirty and dank! After what they did, it's now nice!! We can store things down there and the kids even have a play space. So my house has gained a lot of workable space because of what they did. And it smells better too! My only regret here is that I didn't know of them 10 years ago! If I had known about them then, I would have had a lot less frustration and expense along the way!

I was dreading having work done on the basement, but the team at Harris made it bearable. Angela in…read morethe office is very responsive. Each interaction was well informed. John came out to do my estimate and made me very comfortable with the process. He was great at explaining what would be done.Tim arrived to do the work and what I thought was a major undertaking, he saw as routine. He and his team were pleasant, professional and efficient. I am truly pleased with the outcome and look for to a leak free basement.

We paid $10,000 for our crawlspace to be encapsulated in 2023. I would think the key aspect of…read morekeeping the crawlspace dry is the dehumidifier. The one this company installed in 2023 quit working in 2024 after the one year warranty expired and I had to pay $1,000 to have another one installed. March 2025 the dehumidifier quit again. I called and they sent a technician out here and he said the company no longer uses those dehumidifiers. He inferred that they are of substandard quality and if I purchased another it would be quite expensive. He checked the dehumidifier and said my electrical outlet had switched it off. So, I paid an electrician to replace the outlet with one that doesn't automatically switch off. The dehumidifier continued to quit working. So, I asked an HVAC company to come and check it out. He said the dehumidifier is fills with water and cuts off because it isn't draining properly. He emptied it out and said it hadn't been correctly installed. He said it needed a condensation pump and the tubing needed to be replaced. I tried to reach someone at Crawlspaces and More and for weeks never received a return call. I finally received an email from Jim and he said he would come out and make sure the dehumidifier was on and charge me $200. I told them to forget it. I called a reputable company and they installed a very nice dehumidifier and replaced the door to my crawlspace. Ours was wood and rotted because it was decades old. They said Crawlspaces and More should have replaced it to thoroughly encapsulate the crawlspace. The new company installed a custom fit door that is air tight and sealed. I would not recommend Crawlspaces and More.
