John was very professional and courteous.
Andrew did a great job fixing a leaky toilet the same day I called.
I had my problem diagnosed and today was the day they replaced the plumbing under my sink. They were on time, friendly and efficient. I’m very pleased with the work that was done. I would definitely use them again and I thought the price was extremely reasonable.
Brandon W was very thorough, sought out the problem, and then replaced the outside spigot at our request. A year ago Brandon replaced our water heater that was leaking and replaced a poorly installed bladder done by another company. He has also replaced bathroom faucets and drains for us. He’s a great guy and does a…
Big job this week with replacing some old cast-iron pipe with PVC in a second floor drainage system down to the basement. They did a great job Cleanne efficient got done before their estimated time and then came back and serviced our hot water heater. Andrew was on both jobs and is always pleasant, polite,…
Great neighborhood firm. Prompt, professional service.
Another great job by Howald. John arrived in a timely manner, assessed the plumbing problem, and made prompt repairs, all for a reasonable price. I don’t call anyone but Howald because I know it will be a superior experience. Thank you!
John is a great person to have working on your plumbing issues - he explains everything clearly and is very friendly.
Fast. Professional. Price always reasonable.
Sam did a very professional job! We were pleased with the quick service from Howald and plan on using them more in the future!
I will always use Howald until I'm worm food, and maybe even then to make my eternal resting place more comfortable.
Outstanding as always
Sam showed up on time, was extremely knowledgeable, courteous and professional. Concluded work in a timely manner, and the result was better than expected.
The tech was friendly, professional, courteous, and and answered all of our questions. The work looks quality and he even gave us pointers on how to prevent additional issues in the future - five stars
Howald to the rescue once again! They got a plumber out within a few hours of calling to fix a water leak. As always, they're were beyond prompt and professional.
Update to my previous review: January 2026: Still very pleased with the excellent service provided by Howald. Today they fixed our leaky kitchen faucet & replaced our old water filtration system with a new one we had bought elsewhere. The technician was on time & worked hard to finish the job efficiently. Highly…
Howald always does an excellent job at a fair price. The plumber, John, was professional, knowledgeable, and fixed our issues in good time without rush or delay.
Knowledgeable and experienced
I was without heat and the same day service was very much appreciated. The service was exceptional starting with the call. The woman I spoke with was courteous and professional. She too, needs kudos as that first impression is so important! Dan Powers was courteous, respected my home and thorough. He was pleasant,…
Andrew came out to do some plumbing and was amazing to work with! Their quote was less than other plumbers. They are privately family owned (not owned by private equity) and have done a few jobs for us in the last 5 years. They’ve always done the job well and I’ve never needed someone to come back out and fix their work.
