Response from Klaus & Sons:

Thank you so much for taking the time to leave us this amazing review!

Review
We are extremely happy with Klaus & Sons. Their workers were on time, did what they were hired to do and cleaned up after themselves. That said, the men were friendly and attentive to any questions or suggestions we had. They laid protective padding over the entire work area, and after each days work (2 in our case), they put everything back in place, removed the coverings and vacuumed any materials left. They placed the things they removed in their truck (not in our bins like some workmen we have had)and took it away at the end of each day. We couldn't have been more pleased! Just noticed the question on rating the cost/pricing of their service. They were not the least expensive nor the most expensive, but they were well worth the price!

They continue to take good care of my 35 year old HVAC system, replacing some of the electronics in the blower that I'm pleasantly surprised they could still find. The tech was excellent at explaining what failed, how he was going to fix it and how much it would cost.

James was here on Tuesday. He got the screaming toilet to stop. But it has returned and someone will be out today, Thursday. I just don't think I should be charged another service fee $124.00 since the issue was not fixed.
