I live in a 1903 SF house and needed to replace the tankless water heaters in both flats. I contacted Renstrom and contracted to have them install 2 state-of-fhe-art tankless water heaters. The tiny spaces and the minefield of peculiarities in the house seemed to me formidable. I was fortunate enough to have Steve and his sidekick Ray to do the job. Steve supervised the job, and both men worked non-stop with perfectionist attitudes and did a super job, despite the fact that anything that could go wrong because of the old house did go wrong. Steve and Ray were a pleasure to have around, and I felt their workmanship, their punctuality, their dedication to doing everything absolutely to the best of their superlative ability, and the all-around great job made my choice of Renstrom about the best decision I've made in a long time. Their prices are competetive, and I have nothing but praise for my experience with these folks.
