I had a 30 year old air conditioner that finally gave out. I was worried it was going to cost a fortune... one estimate was over $6,000! Knight came out and literally saved me thousands of dollars. Michael knows his stuff, thanks!

My main water line recently started to leak and I had to have my water turned off on a Saturday. I was able to get 3 quotes for my issue, one of them being from Mike at knight plumbing. I decided to go with knight plumbing because he was honest and didn't try and push me into replacing the whole water line like the other companies wanted to do. The prices are fair and I never felt like I was being overcharged... His price was less than half of what Mr. Rooter wanted to charge me for the repair. I was able to get the leak fixed and water turned back on the next day. Great service and great pricing. I would highly recommend this company.

Knight Plumbing answered the call from our insurance. The willow tree roots damaged the main line to the house. They were cheerful even when the leak spotter put them 6 foot off the leak and needed to dig another big hole.. They sawed many roots some as big as 4 inches across and worked in freezing and muddy conditions at times. Courteous always. Cleaned the area up when done. Highly recommend them to all. Thank You.
