"Services: Unclog drain, Repair toilet, Repair pipe. // Positive: Professionalism, Punctuality, Quality, Responsiveness // Haines was recommended to me saying they were good at their job. I called them Monday, Feb 15th about a clogged drain, they came out Tues Feb 16th at the time I was told they would be there, which was great! They were there from 3:30 pm to 6:50 pm. Some repairs had to be made to the laundry tub drain and my toilet had to be lifted so they could access that portion of the drain. After the toilet was replaced, the shut-off valve leaked, so I asked them to replace that also. The work that was done created quite a mess... BUT, when they were finished you would never know that. Everything was cleaned up so well and disinfected, it looked nice and smelled nice. The workmen were very professional and knowledgeable about their job. I will add this company to my contacts as a reliable source for repairs."

"I cannot recommend this company highly enough. Chris was very professional, nice, informative (without seeming condescending), polite, clean, and fast. He came out the next morning and fixed my problem before noon. Look no further, this is definitely the company you want."

"I thought my kitchen was the only problem but it wasn't. Mario was so patient and fixed more than my clogged drain. The plumbing was messed up really, really bad. He spent some time trying to correct the mess from pipe being improperly installed and the many leaks it created before he could unclog the drains properly. I would use him again and I have highly recommended him to others already."

"James was very nice and professional. He was very punctual anf informed. He told me that there may be a spot that needs to be redone and they would come back. I called and sent pictures. Talk to owner Marc and was like he would be coming out thr following week. Nonetheless never head back. Money down the drain. I've called several times and now not answering my call."

"Performance Plumbing provided professional and prompt service. They quickly assessed the issue, provided an upfront quote, completed the work (cleared a clog in the sewer line between the house and the main, then cleared another clog in the internal line leading from the kitchen), and charged exactly what they had quoted. I would definitely use them again. Thank you, Jesse and Drew!"

Drain Cleaning FAQs, answered by experts

If you’re not using a septic system, problems with your home’s plumbing won’t cause this—it’s a city problem. A large blockage in the municipal sewage lines may cause those lines to back up into your home. This is extremely unpleasant and can be a serious health risk due to bacteria and other contaminants. If this occurs, call a pro (or your city) immediately.

When you put baking soda and vinegar down the drain, they chemically react and help break down clogs. It’s not going to work for every type of clog, however. For example, it’s not the best way to get rid of grease buildup. For grease, you should try boiling water and white vinegar instead.

Baking soda and vinegar is a great solution for cleaning your sink drain; in fact, it’s our preferred method. Here’s how to unclog your drain with baking soda and vinegar: Pour in a half cup of baking soda, then 1 cup of white vinegar, and let the two bubble for 15 minutes. Then rinse out with boiling water. This method is much safer than using a chemical drain cleaner gel.

No, you should avoid using liquid drain cleaners. These chemicals, often packed with sulfuric or hydrochloric acid, can wreak havoc on your pipes, causing erosion and potential leaks. They’re also dangerous to your health. If you’re dealing with a stubborn clog, manual removal or a professional plumber is your best bet. Chemical drain cleaners can often make things worse, especially if the clog stays put and the chemicals linger in your pipes.

Grease buildup, tree roots, and foreign objects often cause blockages. Regular maintenance prevents major issues.
