Came out on a Saturday with only a moments notice. Had to unclog a drain in a home with plumbing so old they had to make sure they did not crack the ancient pipe. Super efficient and with great success. And a very pleasant plumber. Totally reliable and would highly recommend. Thanks

When we had a sink leak, I called several plumbing companies to schedule an appointment. Klaus & Sons were the only company to answer their phone and schedule someone the same day. The plumber was friendly and got the job done quickly. The price was good and we have called them a few times since.

Best plumbing and air conditioning place ever! I have used them for years and dont have plans to call anyone else. They are personal professional their prices are comparable to others but their expertise far surpasses others. Call them before anyone else!!

I've used them twice, first time, great service, fair price. Second time, plumber had no people skills, seemed indifferent. Work was ok, price was overpriced. Only did half of what I wanted due to his over priced quote

We had a leaky toilet that our local water company alerted me to; I'm a DIY type homeowner, but I don't have much trust in plumbing parts from big box stores.

Klaus & Sons has done previous plumbing jobs for us and we've had no issues with their workmanship. So, a quick call to Klaus & Sons, a friendly, professional receptionist scheduled me for a next day appointment. Job well done! Thank you Klaus & Sons!!

The plumber was respectful and very helpful. The cost to put a snack down one drain with a plumber in my home for maybe 30mins was $179. The owner said they waived the after hours fee but it did not feel like that. Then to go into my bathroom and see that he put the overflow drain back on with the drain access on the side not the bottom was frustrating. I want to call and have him return but it is just easier to do it myself.

Sal came out to check some work they did spent a couple hours finding it was our main line he was very thorough he fixed it the next day and they did a great job. Can't hardly even tell where they had to dig up our yard. And they fixed our concerns. I would recommend them to everyone
