"I found the leak in the attic and knew exactly where to find it. I had to let them go through my room ceiling after looking at where the burst was located. No way they could get to it any other way. Job done in an hour. Is $1k to expensive? When 1000's are experiencing the same issue? No you do what you need to do to come back online. I was happy with their business. They explained how to avoid this in the future."

Welcome to Resolute Plumbing and Heating. We have been in business since 2013, with over 20 years combined experience and are the answer to all your plumbing needs. No project is too large or too small. We strive for superior customer service and satisfaction is our guarantee to you. We are professional and friendly. Call us today!

"Jeff is amazing, transparent, thorough, and polite. Would 100% recommend him without hesitation. We had a different HVAC company out for the same issue. Their technician was here for ~4 hours, had little experience with boilers, and walked away quoting us $800 (in addition to the $150 it costs for the diagnostic) to replace a part he was "fairly certain" was the problem. Since that visit did not fill us with confidence, we looked for other companies and found Jeff and Resolute Plumbing and Heating here on Homeadvisor. Thank goodness we did!! From the first contact with him on the phone he was open about his thoughts on what might/might not be causing the problem. Clear about pricing, and very accommodating in scheduling. On the day of the appointment he was here for about 2 hours, much of that time he spent educating me about our system, and left having solved the problem with a simple repair he did on-site, not replacing the entire part. He was friendly, straightforward and a thoroughly enjoyable person to have around that entire time. His time and expertise to SOLVE the issue cost us less than what we paid the other company just to do a somewhat uncertain diagnostic. Thank you Jeff! You are our new go-to, and we are so grateful for your time and skill."

"We had a clogged pipe. Logan came out as part of their 93 or free deal they had for clogs. Logan was professional and did excellent work. He had to remove the toilet to clear the clog, which was discussed ahead of time and a reasonable fee on top of the 93. Clog was cleared and all went great!"

With 25 years of Industry experience we are here for all your Sewer System needs. From installations to repairs we handle it, and being locally owned and operated means that you get the highest quality service and response time every time. Give us a call today for your Sewer System needs!

"They helped fix an emergency sewage backup issue, but the external clean-out point should have been placed at the back-end corner of the house rather than the front. This placement missed access to the back-end area, which could be necessary if a liner installation is needed later. That said, hindsight is 20/20. They did a reasonable job based on their proposal, but at the time, we didn?t have enough knowledge to request a better plan. One issue I encountered was their tendency to revise estimates upward during the project, which I did not appreciate. Additionally, they were uncertain whether the sewage and storm drainage systems in my area were separate or connected. Compared to other providers I worked with later, this suggested a relative lack of experience or knowledge. Another concern was witnessing one of the workers urinating in the hole they had dug during the process. I found this unacceptable and feel it?s worth noting. Finally, I recommend checking out https://lni.wa.gov"

Holmstad Plumbing, Inc. is dedicated to providing our clients with the very best in service for your plumbing needs. Holmstad's Plumbing Inc. has been servicing the Snohomish County area since 1908. In 1993 we purchased Holmstad's Plumbing Inc. when the prior owner Larry Larson decided to retire. It was a no brainer considering I had already been working for Holmstad's for over ten years and had built a relationship with many of the Holmstad's customers. At the time Larry Larson was the third owner. We are a locally owned and operated company with years of experience in the industry. We specialize in a variety of residential and commercial services and take pride in the attention to detail put into each of the projects that we're involved with. At Holmstad Plumbing, Inc., we're known for the quality of our work, commitment to outstanding results, and the integrity of our business. We look forward to building long-term relationships with our clients, and guarantee your satisfaction.

"They did 2 projects for me: In 2022 they replaced my bathtub, and while doing that job discovered the floor under the toilet was rotten. They replaced the floor under the toilet, as well. While this added to the cost of the project, it was very reasonable. This year they installed a new dishwasher. When it appeared there might be a hidden leak, they came back out and ensured that everything was stable, and there were no leaks. They are very thorough and efficient. I also appreciate the senior discount."

A family owned business over 10 years of experience, I've done and loved all aspects of this job. We value intigrity and take pride in the attention to detail put into each of the projects we're involved with. We look forward to building long-term relationships with our clients.

"Optimal Sewer & Drain, LLC performed a hydro cleaning on my sewer line. They did a very thorough and professional job. The nature of the project changed as the discovery of a septic system, unknown to me, presented a big challenge for their equipment and to me as the homeowner trying to sell the property. Denzyl, the owner, was very kind and patient with me as I tried to understand the implications of their findings. We had to get another company involved and Denzyl went above and beyond to ensure smooth communication and full understanding of the issues was relayed. He and his crewman Dan demonstrated the highest levels of integrity and honesty in their dealings with me and I found it very easy to trust them. They helped turn a stressful situation for me, into a pleasurable one. They gave me a video of the cleared sewer line and cleaned up the crawlspace and worksite before they left. I would highly recommend this company."
