At Cocos Plumbing, we will always provide a competitive bid on any job we provide an estimate for. And we certainly beat our competitors sometimes on cost. But overall, we put our focus on Value, not just Price.

We will never strive to offer rock bottom pricing, because everything else we deliver to our valued customers would then suffer. What does the focus on Value mean?

It means we are incredibly responsive to our customers, there whenever you need us. It means we do the job right, and the first time. It means prompt and highly efficient service to you at all times. cocos-plumbing-st-louis-county-city-residential-commercial-plumbers

When you’ve been in business for over 90 years (we were founded way back in 1925), you learn a thing or two about what customers really want. And we’ve found that being the most knowledgeable, professional, well-experienced and relationship-based licensed plumbers in St. Louis and the surrounding region, especially south St. Louis County – Lemay, Mehlville, Oakville – has served us pretty well, over all these years!

And this focus on Value is one of the primary reasons that so much of our business comes from referrals.

Re: Recent Work

Joe:

Writing a $7,400 check for work performed on one’s house is not a pleasant experience. However, the expert work performed by and the professionalism of the Cocos workforce made writing the check very satisfying.

During my forty years in the construction industry I witnessed many workers who performed their work in a professional manner while working extremely hard. Chris, David and Joe are some of the best professionals in our industry.

The work; and tthe manner in which they installed it, performed in three days by these gentlemen is amazing. Cocos Plumbing is fortunate to employ such quality personnel. These three truly exemplify what the term “Build Union” really means.

Thank you for the great job and the “all new” sewer system. Please know that Cocos Plumbing will receive my highest recommendation to anyone needing plumbing services.

Sincerely,

Hear What Our Customers Say

  • Our pipes froze and burst in our garage. Cocos Plumbing sent someone over right away. I was relieved to have them fixed before any water damage occurred. Thank you for the prompt, courteous service!

  • Opening up a new restaurant is stressful enough without worrying about the quality of your plumbing contractor. I am extremely pleased with the work Cocos did at Epic Pizza.

  • We had a full kitchen remodel that we needed some expert help and advice on. I can’t think of what the guys at Cocos could have done better. They helped us pick out the exact faucet and sink to compliment the room perfectly, and installed a new garbage disposal that should give us many years of hassle free service. Can’t say enough good about them! 5- stars.

  • When we remodeled our bathroom we called Cocos, recommended by a friend, and were very pleased with their service. Very knowledgeable and professional, and had a great selection of products to choose from. When you need a plumbing contractor in St. Louis, these are your guys. Our bathroom gets compliments all the time - Recommended.
