Crawlspace work. Insulation, etc. Got done on time, even with more needing to be done than we thought. Friendly workers, kept the rest of the house clean while working in a dirty crawlspace.

Jacob showed up when he said he would, and got done when he said he'd be done. They hand dug my subgrade first floor by hand and installed a new vapor barrier. I give him a 10 of of 5 stars.

EXCELLENT- Polyseal team with Trace and Logan were especially helpful, responsive and professional during a crawl space issue. Once I got scheduled, the job was completed in 4-days. Removed water, reinstalled insulation, new vapor barrier, piped in new drains and replaced sump pumps. I would definitely recommend them and call them again!

Yesterday, May 7, Jacob and Evan showed up at our warehouse to insulate the two ends. I was definitely impressed with the job they did. They wasted no time in getting started, covering things so that no overspray got on anything. Their ability to resolve problems in reaching some of the areas that were a bit difficult, was encouraging. They were friendly, professional, and a pleasure to work with. I would also like to thank Trace for coming in giving us a bid and then revising it a year and a half later when we finally decided to go ahead with the work. And I would like to thank Logan for scheduling and calling us when he had an earlier opening. Polyseal did a good job for us and I would like to thank all of them.
