We found an unexpected water leak, called Stang Plumbing and they responded within the hour on the same day. Jeff arrived promptly and was very knowledgeable and helpful. He got right to work and helped us start digging into the problem. The problem ended up being more complex than anticipated and we got extra help from John, who was also fantastic. They recommended a restoration company for us to work with and made sure we understood all elements of the issue. Very happy with the service and would 100% recommend or hire them again.![]()

This was our first time using Stang Plumbing for a problem in our upstairs shower - replacing an old broken diverter valve in an extremely tight space. To say we are happy with the results would be an understatement. Jason Morris, the plumber Stang sent over was not only personable but focused, professional and efficient. This is a guy who knows exactly what he's doing! To make things even better, the cost was by far the lowest from over a dozen calls I made to other services. We are "5-star" happy with the results! A huge shout out to the crew at Stang.![]()

Second time using Stang Plumbing & Heating and very pleased with their service! Jaison was very dutiful and polite. He took the time to explain things and was very knowledgeable and nice. His experience definitely shows. He got both jobs done in no time. Also, the front desk lady's reception was very pleasant and welcoming. This is a company run by and comprised of good, honest working people who value professionalism and transparency. (A rare find these days.) Happy to call on Stang Plumbing & Heating again and again =)![]()

During a recent major snowstorm, my water heater failed due to a blocked roof vent. I discussed my problem with Dawn of Stang Plumbing and John and Rob arrived the very next day to analyze / troubleshoot the problem. As a result, they formulated a plan to identify / remediate the problem. I’ve used their plumbing services many times in the past and I’ve always been very satisfied. They are all extremely friendly and very competent professionals. I would highly recommend to my family and friends!![]()

This is the fourth time over the years, that I have used Stang Plumbing. One time for a leak in the basement, once for a new kitchen sink and faucet install, with me supplying the faucet and the sink, another time for repair of a leak under the kitchen sink. And this time for a garbage disposal install, with Stang plumbing supplying the disposal. Each time they were responsive with an upfront price quote. Each time they arrive the next day as promised. All their personnel are polite and professional. Each time the job was done right and the technician left the job site neat and clean when they finished. I think their prices are resonable and competitive, and I do like that they have senior citizen's discount. Stang Plumbing will always be my first choice, when it comes to my needs for any plumbing work.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.

| Feature / Consideration | Professional Stang Mechanical Cabling | Chemical Drain Cleaner Bottles |
|---|---|---|
| Clearing Action | Physically cuts, breaks up, and pulls out dense grease, paper, and hair blockages | Uses corrosive acid or caustic lye to dissolve organic top layers while leaving hard plugs intact |
| Pipe Safety | Safe for all pipe materials, including PVC, ABS, copper, and original cast iron lines | Chemical reactions generate intense heat that can soften plastic pipes and corrode old metal joints |
| Long-Term Effectiveness | Clears full internal pipe diameter to prevent rapid re-clogging and recurring backups | Briefly melts a tiny channel through the clog, allowing the blockage to close back up within days |
| Health & Air Quality | Completely chemical-free process that keeps indoor air safe and toxic fumes out of your home | Emits noxious chemical vapors into small bathrooms and risks splashing skin or eyes during use |

Avoid washing cooking grease, coffee grounds, and stringy food scraps down kitchen sinks. In bathrooms, place hair catchers over tub and shower drains, and flush only toilet paper down toilet lines.
No. Chemical drain openers typically melt a small hole through soft organic clogs without removing wall-to-wall buildup or root intrusions, while exposing your pipes to corrosive chemical heat.
Recurring clogs in older residences are often caused by interior pipe scale buildup on cast iron lines, deteriorating pipe slopes, or invasive tree roots penetrating main sewer lines underground.
Yes. A slow drain indicates a narrowing pipe passage. Addressing it early prevents sudden overflows, unpleasant sewer odors, and complete wastewater backups into lower-level fixtures.
