10-12. CALL WHEN IN ROUTE. I spoke to Robert, they have a slab leak occurring in their bathroom.

(8-10) Mario ONLY. Possible callback. Spoke with Debbie, Mitch's wife. Mario was out to fix a toilet leak and she said that the toilet tank currently feels pretty loose. They don't know if it's possible to get it tightened or if it's even related to the previous work done. Please get approval on any pricing BEFORE performing any work!

8-12. Call the daughter (909) 331-7499 | Daughter Elizabeth when in route. I spoke to Elizabeth the thermostat is not working right to the ac unit. She also mentioned maybe trying to get the fireplace cleaned out? Said we did it the last time we were out there. Will confirm with Dan before the appointment.

12 - 2. COD. Spoke to Daniel. Sink backed up needs to be unclogged, started about 3 or 4 days ago. Please provide pricing before performing work!

12-2. COD. Call when in route. I spoke to Mitch, they need their toilet to be reset as it is leaking from the base.
From the time that I called to ask for service in a stressful situation in regards to my plumbing, I was kindly acknowledged and given a same day appointment. The technician, Mario, was professional in assessing my plumbing matter. I was referred to Klaus and Sons by a friend and I’m very very satisfied with my appointment outcome so far.

2-4. COD. Call when in route as she is a teacher and needs to leave work to get to property. I spoke to Sandy, when they run their washer there is water coming out of her light fixtures and she doesn't understand why.
Jake arrived on time and replaced my leaky valves promptly! Gave me great advice and answered all my questions! Thank you Jake!!
Service was fantastic! Same day service. I was definitely impressed how fast they came out and called me back right away. He inspected everything. Highly recommend!
Had little bit problems with faucet size, but at the end he resolved the problem.

This is my second time using Klaus & Sons for plumbing issues. Both times they were able to send a tech on same day and fix the issues I had. Would absolutely recommend and use again!
This is our second time using Klaus & Sons. First time was for an AC issue and this time was to install a new water heater as are old one died. We are extremely happy that we found them on Nextdoor and called them for our service needs. They have reasonable prices, they are honest and explain everything so that we understood what was going on. Jake, who came out to install the new water heater was great!
I had a new gas line run through the attic to the kitchen and a couple of leaks repaired on an outdoor gas line. The technicians arrived promptly when promised, performed the work efficiently, and were mindful of the cleanliness of my home.
Professional service
