Encapsulated crawlspace

Jason and his crew did a great job encapsulating our crawl space. I had noticed condensation in the crawl space a few times and after some reading online, I realized that having a closed crawl space is the most appropriate way to deal with moisture issues. I interviewed 6 contractors and Jason won my business because of his knowledge and a fair quote. The job was done in a couple days and everythi...

I had a horrible experience with them.  He was just horrible.  I really just intended to sit down and write a novel about how horrible the experience was.  It's one of those things that's not readily awful until you realize something went wrong.  Then when you realize that something went wrong and you actually realize what he actually did it's like wow, your a scumbag. 

He did our basement waterproofing.

THESE DETAILS ARE A CONTINUATION OF MY LAST REVIEW: PERMITTING ISSUES: On October 14th, I sent Jason a text message asking when the job site would be cleaned up and when the job would be permitted. He tried to suggest that there was an issue with the permit – because I pulled it, not him. It took 5-6 text messages back and forth to get Jason to understand the Town of Cary issued me the permit base...

ESTIMATE MEETING: My first meeting with Jason Mullins of Crawlspace and Basement Technologies was on 8/28/13. After interviewing several top-rated Angie’s List companies, Jason was the final company to interview for the job of resolving the issue of moisture in our crawlspace. Some companies wanted to suggest vapor barriers; but the majority of the specialists I met with suggested a sealed crawlspace, which is what Jason also suggested. We discussed a plan of attack, timeframe, and what would be included in the job. We talked about costs, lifetime warranties, etc. There were two things I remember distinctly from my interaction with Jason that specifically won him my business, #1 he didn’t want a copy of the home inspection report we received in June, he wanted to take an independent look at our crawlspace. #2 he provided a list of references, provided copies of licenses and insurance, and provided all necessary paperwork during his initial estimate. Those two things, along with the fact he offered a fair price won Jason Mullins (and Crawlspace Basement and Technologies) my business. Jason was kind, friendly, and gave me reassurance that he was the right man for the job. CONTRACT & NEXT STEPS: We setup a contract at the end of August with an installation date of 10/11/13. We were told it would be a 1-day job and that payment was expected upon both job completion and permit approval.

We are surprised by this review and its content. This was a young couple that we tried to be flexible with and we tried to help them out. If you look at all of our other reviews on Angie's List, you will see that we have many satisfied customers who have given us very high ratings. In fact, our reviews are so good, that we are a past Angie's List Super Service Award Winner. We pride ourselves in d...
