When our dishwasher sprung a slow leak that leaked into our crawlspace, but evaded detection until our kitchen floor tile started cracking, we called around to various crawlspace companies. Crawlspace Doctor was by far the most responsive and took great pains to explain their philosophy and methodology and that earned our business. From the outset we dealt directly with company president Matt Bagdonas, who was extremely gracious and always quick to answer questions throughout the process. We ended up contracting them to remediate our crawlspace, by installing a dehumidifier and enclosing the crawlspace (we already had a good moisture barrier installed). We then utilized them to shore up our flooring and remove the old tile, and replace it with new.
We are completely satisfied with the state of our kitchen floor now. David, the gentleman who oversaw the concrete pouring for the support posts and beam they put in, and also the tile demo/installation, was just as responsive and available as Matt. The kitchen floor looks great (aside from our young kids immediately dropping food and so forth on it :-)).
We did have two complaints; one was that no effort was made to keep the dust from the demolition out of the rest of our house--this may have been due to a misunderstanding on our part though, we were under the impression that they would put up some barriers, but maybe we were supposed to plan for that on our own. In any event, we consider it unlikely that any barrier could have kept all the dust out, so some significant cleaning would have to be done after the install no matter what. The second was that someone used our clothes hamper as a garbage can, and I dumped it in the washer and then had to fish out chunks of masonry, nails, and sunflower seeds out of the washer tub once I realized what had happened.
We did not bring these matters to David's attention, as there was not really anything to be done about it after the fact--so we still feel good about giving a 5 star rating because the job really was done well and that's what we care about. When we did have an issue or concern and brought it to his attention, he and his fellow workers did everything they could to make it right, so we have no reservations recommending this business to anyone.
