Toilet leaking from base and wobbling needs reset

2 - 4 (REQ FRIDAY & after 1pm). COD. Spoke to Diane. She received a coupon for $149 exterior drain cleaning and something about a camera inspection included. Please look at coupon. She isn't sure if this will work for the issue she has, but she said that her toilet has been gurgling for a few weeks and especially after the washer drains. She said the gurgling recently stopped but would like it checked out and is also curious what this coupon does entail.

8 - 10. NET30. Spoke to Maria. Need to hydro jet plaza, main line on south side. 2 tenants have places with toilets backed up. We did north side couple years ago and it's been great. This is going to be for 12634, 12632, 12639, make sure all toilets flowing afterwards. Go to 12634 back side first, alley between plaza and saint Maragaret Marys – the cleanouts are there. Mary is going to come put cones where clean outs are so no one parks there. If you have any questions - Call Mary @ (909) 957-3077. You will be billing El Central Real Plaza.

Rescheduled for 10-12 on 4/15/25

8 - 10. Moved call to Friday per Sal.

Klaus and Sons provided great customer service from my call to request service to completion of the job. Thank you!

Nothing was wrong with toilet. Tested multiple times


8 -11. Per Wes, customer approved estimate and scheduled for Friday.

2 - 5. COD. Spoke to Eddy. PM on unit. He did say there is an odor when they run the unit, musty smell. Our install (it looks like we only did the AC and not furnace?) but he hasn't had maintenance with us in 3 years so I recommended he do that, and we can check out the smell. Quoted $158 for the maintenance. Please confirm if he would like to do a full system maintenance or just on the unit with the smell and adjust the price quote accordingly before performing any work.

8 - 12am. David picked up thermostat, coming back to install. Scheduled with customer - REQ Tuesday morning
Excellent communication arrived on time gave us a detailed description of the problem
Thank you so much for your 5-star review! We will share this with the team to let them know to keep up the amazing work!

Updated customer that Wes will be there closer to 9am


1-3. COD. I spoke to Marvin, their water heater is not working right, he thinks the pilot light went out. He wants to see if it can be fixed or if he needs to replace it as it is about 12 years old.


8-10. COD. Call when in route. I spoke to Mitch, they have a leak under the kitchen sink. Attached photos.

2/19/25 The client refused to pay. Unit has numerous issues. We advised to call the company who installed. Please do not send us back.

10-12. CC on file. COD. I spoke to Michelle (909) 628-5501, she is a manager and can give approval for work. The womans restroom has a toilet that will not flush at all and they have a toilet in the mens restroom as well.

4-6. COD. I spoke to Helen, their drains in the bathroom are all backing up, and so is the washer line, she said this has happened since they put her new washer in.
Thank you!
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
