"I had a water main break at my house. It needed to be taken care of immediately. I found 8995 Sewer Drain through the Angi service. Carl came to the house the same day, looked the work over and gave me an excellent price. He was there the next morning working the job at 7:30am. Knocked it out in no time. Very happy with his workmanship, promptness and pricing. Would definitely use Carl and 8995 again!!!!"

"Hands down best contractor we have ever worked with and highly recommend. Anthony was honest and determined to repair our horrible plumbing that we have had problems with for years. At 61 years of age I know excellence and integrity and Anthony has both in loads. He is a master plumber and his work ethic far exceeded our expectations. Red Lion provided excellent expert service at a fair price and we are grateful to have e found them."

"We had John do our plumbing job. He was excellent. We had a hose that was attached to the outside of our house, that would not come off. We had several people try to take it off, no use. He was able to take it off without breaking the pipe. If i need a plumber again would definitely ask for him."

"After 35 years as home owners on Long Island, this was our best plumbing experience ever. Nothing was too much trouble for Frank. Our downstairs bathroom is in an annex to the main house, built over a crawl space accessible via our basement ... if you are agile and determined. Frank crawled in there on his back to check there were no leaks from the work he'd done above. (There weren't any.) There were a couple of parts he didn't have in the van: he said he'd come back in a few days to instal them. He did -- no extra call-out charge. Great customer service; great workmanship; great plumbing; THANKS!"

"Anthony and his crew did a great job in providing and installing the exact system that I had requested.  
They were thorough, professional and very neat and very easy to work with.  The installation was completed in one day.
The pricing was more than fair.  I couldn't be happier with the new A/C system.  I highly recommend APV to anyone in need of a new central A/C system.

"A real find! We've had many plumbers, good and bad, but by far, Clearway was the best! I called them yesterday with two issues: a leaking relief valve on our water tank, and a slow draining toilet that coughed up grey gunk after 2 days of Draino Max Buildup treatment and plunging, yet wouldn't drain properly. Jim Montalbano got back to me very quickly, gave me the low-down on what was most likely happening, and sent his team over bright and early today. Paul and Adam were polite and very easy to talk with. (We've experienced plumbers who treated us with condescending attitudes, so this was a pleasure!) They explained what was wrong, what needed to be done and did it so quickly and professionally, we were astonished! We would definitely have these guys back for future projects, and we thank them and Jim for a job well done. Highly recommended!"
