The existing plumbing company began in 1978 as Dave Filan Plumbing in Cherry Hill, NJ with over 38 years of experience in the tri-county area. Dave Filan's plumbing service and bathroom remodeling organization has one of the best reputations for service plumbing and residential bathroom design and bathroom remodeling. Brian Conner's Plumbing organization, started in 2002, as Brian Conner Plumbing and was in business for six years focusing primarily on the plumbing needs of residential new construction. Brian Conner Plumbing was known as one of the premier plumbing sub-contractors and worked with some of the area's best known and most well respected builders and remodeling contractors. In June 2008, Brian and Dave brought both plumbing companies, with overlapping but different plumbing service offerings, together to form Filan & Conner Plumbing, LLC. The combined experience, leadership, and expertise of both Brian Conner and Dave Filan creates a powerful team as they work together to direct this increasingly diversified plumbing company.

"It is unknown if ChristianConner has anything to do with this company , the previous review I posted about not being paid for services I rendered to Christian had absolutely nothing to do with this company after doing some research and conversing with Christian conner , I was paid for services, I am writing this review due to the Angi website for some reason not navigating the removal process of the prior negative review ! Filan and conner plumbing is a a+ company and was not involved with this service ."

The number one reason to hire a local plumber or home improvement contractor is proximity. While working with Alliance Service Pros, you're guaranteed to get that fast, attentive service, but you'll also receive a variety of additional benefits: Above & beyond service: We go that extra mile to ensure total, 100% satisfaction in everything we do. Community driven: As a locally owned & operated company, we always give back directly to the communities we serve. 5-star reputation: Our reviews are solely from customers in the local, immediate area, like you.

"AVIOD at ALL cost !!!! Jake is a fraud he delayed my entire project by three months. he was hired to make plans for project and give us kid drawings with pencils and crayons with all stains on them. delayed our project for over 3 months in over 20k in damages . and this man is nasty just takes money and hangs up . the city inspectora even laughed when we submitted his plans . This company is nowhere near professional and all they do is steal money . stay far away !!!!!! If anyone wants to join my lawsuit contact 848-248-6834"

"They did a great job on a sink and toilet installation. They noted some other plumbing issues I had, but, even though I followed up twice they never gave me a quote. Was pleased Werth work they did, but disappointed with lack of follow through."
