The best by a wide margin. I've been on a condo board more than a decade in a challenging location built over Lake Washington in 1969. For more than 10 years we received bids and rejections from a half dozen plumbers large and small that hesitated to remove cast-iron drain lines embedded in our concrete slab. Some plumbers cherry-picked the easy parts and skipped sections that needed replacement. Others failed to meet building code but charged us anyway as the system continued to degrade. ProMax was the first company to carefully analyze and bid the entire job, and they completed 100% on time and on spec with zero hassles or mistakes.
We have switched all our Kirkland condo plumbing business to ProMax, and I'll be doing the same at a Seattle condo association.
High quality work! I’ve hired Evan in the past (water heater replacement, water supply line leak, a pin nail through a cold water line, and replacing old shutoff valves throughout the house) and always gotten high quality work and advice. Basically ask for his opinion and he will give you the reliable solution he would use in his own home rather than the most profitable solution.
Being without a kitchen for 4 months after a pipe break, I called ProMax and Evan answered the phone and immediately got me into his schedule which was the next day. Yay! He was friendly, efficient and got the job done. I cant recommend this business enough.
