Hi, my name is David Tarrence.

I began working for Crawlspace Doctor as an evaluator in October 2006. Since that time I have really enjoyed working with and improving the conditions of my customer’s homes, helping them get a healthier and more energy efficient home.

It is my top priority to always deliver a very thorough and professional evaluation of the homes I inspect; providing honest, professional, dedicated, and timely service to each of my customers’ crawlspace concerns. I look at every customer as not just a client but as a friend for life, and always make sure they know not to hesitate to call me if they ever have questions.

So if you live in Hendricks, Morgan, Vigo, Parke, Putnam, Sullivan, Clay or Vermillion Counties, contact me today for a free evaluation and let me help you with your crawlspace concerns!

  Our experience working with Dave Tarrence and the Crawlspace Doctor was EXCELLENT.

Dave is very knowledgeable, friendly and HONEST. He went out of his way to explain the process, and spent several hours on the phone with us to clarify plans and procedures. We considered quotes from 5 other crawlspace companies, and were never confident that they were telling us the whole story. We never got this “run-around” during our conversations with Dave.

In terms of the actual work, the foremen on the job were prompt, polite, and hard-working. We are extremely pleased with our crawlspace and would not hesitate to recommend Crawlspace Doctor, but more specifically, Dave and his crew, to anyone considering encapsulation.

  Dave and his team were awesome! Dave showed me pictures of the crawl before the work, talked me through everything we needed to do, and quoted a very fair and detailed price.

Dave was very accessible through the whole process, and his team was so professional. They were courteous, cleaned up everything, did an amazing job, and even hand dug our sump pump line! Dave came back and went through the whole space with us.

So, what was a damp, dirty crawlspace is now a dry, insulated, beautiful crawlspace! I am worry-free now about mold and standing water under the house, and on top of that I have a beautiful crawlspace door and new insulation.
