Highly recommend! Jake has provided access to other tradesmen, repaired our plumbing, done tile, plumbing and painting projects in our home, and done field mowing with his own equipment. He does the job and more. He is especially considerate of seniors. Jane & Don Palmer (Damascus)

Destroyed property with equipment and has refused to fix it and complete insurance bid. This has been going on for over 5 months. He did this to a widowed 90 year old. Unprofessional and aggressive manner.

.Also highly recommend! Jake completed a number of home improvement projects for us and did an outstanding job. He is an extremely precise, creative, and artful carpenter. All who worked with Jake — electricians, plumbers, tilers, dry wallets, painters, landscapers, etc, — were highly qualified and professional, as well. We could not have been more satisfied. Jake treated us with great respect and went out of his way to listen and give us exactly what we wanted and more. All of our friends and neighbors are impressed with the work Jake did for us — as are we. You will not be disappointed.
