Good job, expensive. If you haven't called a plumber before be aware that there is a 30.00 if you pay after 15 days (I am probably at day 16). Also, a 2.5% charge for using a credit card. Is it worth it? Phone call to clear things up? Got a friendly response. So, yes, worth it, but be aware.

This company has been very reliable at times when we really needed help, including once when our boiler failed, and another time when our sewer line to the street became plugged. On each occasion, Carlson Brothers worked tirelessly to get our systems back, and they did it courteously and with good humor.

My husband and I were highly displeased with Carlson Bros. We used them for a water heater replacement and they left the place much worse than when it started.

I hired this company to do some plumbing work on a bathroom and kitchen job. They were super nice and came over to the job t he following week. Today I get the bill and I am charged almost 2000 dollars for a days work. $144.00 An hour overtime? They were there 6 hours. Truck surcharge $10×4 ??? AVOID this company. This is not a good way to do business at all!
