2 -4. Spoke to Zoe. Per Jesse, send Sal. Same toilet we have worked on before a few times is still leaking from very bottom from the tank. Old tech Bryan installed this back in Nov. 2023. Amen came out a few times for leaking of it and spoke to Jesse about how the gasket can't be reached because of how it was installed. They have called back multiple times for it leaking. It probably needs to be completely replaced. Please take a look at it and see what's going on and ask Jesse what he would like to do.

2 - 4. Spoke to Keith. Call when on the way!!!! - (909) 938-2564. Possible call-back?? Andrew was out last on April 29th, installed new TMP valve for water heater. Keith said: Valve was holding for a while, not holding any more, might be issue with regulator valve from city that goes to street. It was fine for a few days but now leaking… too much pressure coming through water heater to line. Also, about a year ago, we changed the pressure control valve to house, may need to be readjusted or failed. Hears water and air escaping through the relief valve. Please check out

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.
