What customers said about sump pump repair
Karlsen Plumbing Inc.Great service. They did their best to give me a quick appointment. Very professional and kind service technicians.
Knight Plumbing & Drain CleaningResponse time from initial phone call to service call was extremely prompt. They arrived the next day. I was having backup battery to sump pump issues. The alarm would come on and you had to manually turn it off. He explained options and was very informative. I would recommend this company to everyone!
Karlsen Plumbing Inc.Karlson Plumbing is very professional. On time with an on the way courtesy call. Diagnosed our problem and then had the proper parts to fix things immediately. They are my go to plumber.
Karlsen Plumbing Inc.They had to come twice so I paid 2 service calls as they jiggled it first time and it began working only to fail again within 2 weeks. They also knew I requested the pump to get replaced in second call and I also had to pay time to warehouse to get a pump since those are not on their truck yet they knew it needed to be on the truck!
Karlsen Plumbing Inc.Scott installed a new sump pump for me, did a great job, very clean install and told me how I adjust water levels. Superb.
Knight Plumbing & Drain CleaningAndy came out to my home to provide an estimate. I thought he was very knowledgeable, professional and patient. I haven’t had the installation yet. This will be done in the near future.

How we grade

Reliability (24%) — How rarely jobs go badly: share of 1–2★ reviews — 60% the last 24 months (or the 20 newest if fewer), 40% all-time; 0% = 100, 15%+ = 0; the category percentile can only raise it.
Craft & service (penalty, up to −10) — Google review highlights: Quality, Professionalism, Responsiveness, Punctuality — how rarely reviewers flag them as a negative, per review since highlights began; 0% = 100, 5%+ = 0. Subtracted from the score (up to −10), never averaged in — clean highlights are the norm, not a bonus.
