What reviewers report — the concerns
Other directories bury these. We think you should read them before you call. Every concern below comes from the reviews it cites.
Red flag
Written estimate for 'broken, exposed, and collapsed' sewer pipe at $5,300 — second opinion found no such damage, pipe just needed cleaning. Scare tactic accusation substantiated by customer's own inspection
“WARNING! DO NOT USE THIS COMPANY! I received a written estimate from Kwik Serv Plumbing to have my sewer line repaired. They insisted and put in writing that I had a 'broken, exposed, and collapsed' pipe that needed to be repaired for about $5,300. After receiving a second opinion and seeing with my own eyes that there was not a 'broken, collapsed, exposed' pipe. It simply needed to be cleaned.”
Red flag
Improper HVAC wiring during installation caused pipes to freeze 8 months later; Kwik Serve then quoted $3,300 to fix damage they caused while denying responsibility
“Our home warranty company sent Kwik Serve to replace our HVAC unit, and within 8 months the outside pipes froze. Kwik Serve then gave us an outrageous $3,300 estimate and claimed we'd need to tear open our walls to expose all the lines. Thankfully, we brought in a different HVAC company for a second opinion — and they discovered the real problem was that Kwik Serve had improperly wired the system during installation.”
Red flag

The evidence — in reviewers' own words
Critical
“Leaking still happens after so long time.....I stop using the upstairs bathroom and keep changing paper towels to absorb the water....It took weeks for get the broken parts replaced (it's not installed well; it's loose and I suspect it may still cause leaking). While leaking continues, it took so many calls to secure another appointment and wait all day at home for technician showing up. No one showed up for the …”
“WARNING! DO NOT USE THIS COMPANY! I called this company to help with a blocked sewer line and the nightmare began. This company will use scare and fear tactics to trick the customer in believing they have more of problem that actually exist. I received a written estimate from Kwik Serv Plumbing to have my sewer line repaired. They insisted and put in writing that I had a "broken, exposed, and collapsed" pipe that …”
“Kwik Serve was dispatched to our house via Home Warranty of America. After one cancellation they showed up the next day with only a 20 minute notification - only because we called to reschedule ourselves (never got a call from them to setup the reschedule at all). We were told that they couldn't move forward until we paid a $120 toilet removal fee (which seemed high as other plumbers we have used in the past haven't …”
