I have used Cardinal twice now, both times for plumbing issues. Their ustomer service was great. The first time was a more urgent issue and they had someone out the first day. Both times I had realy excellent plumbers, first Noah then Tom. I would be happy to have either of them come back. They were both very knowledgeable, helpful and friendly.

What a great recommendation! Both gentlemen were knowledgeable and professional. They explained everything to me, answered all my questions and definitely went the extra mile in finding things in my older house. Was glad to become a member of the Cardinal Family plan and have the ease of mind to have all my house needs taken care of by just one local company! Definitely call them for any household system repair or replacement or just professional ideas or answers!

Electrical Switches, Outlets & Fixtures - Install or Repair
We were very happy with the service we received from Cardinal in wiring a new ceiling fan and repairing some outlets and switches in our home. The electrician came on a Sunday evening and was was extremely professional, he discussed everything he was going to do and our options for meeting our goals and he was a creative problem solver as our old house posed some unique issues. In addition, he was quick and very pleasant, he cleaned up any debris generated during the call and worked very hard to make us happy. I was really happy with everything about the visit and will choose Cardinal the next time we have a problem.

The installation ended up beautiful. I had tried to get Sean and Nick to make some alterations that might have helped me to cover some defects left by the siding guys. I'm glad I decided to let them do it the right way, the intake and exhaust disappeared into the joist space and it really looks so much better than if they had accommodated my idea, both inside and out. They arrived on time to the minute, and probably would have finished a little sooner, had I not been pestering them so much. Very professional work. Cardinal needs some praise for training their installers so well. I received duplicate letters from the Building Inspection Division, and have an appointment with them tomorrow. Their "window" for when they will arrive is between 9:00am and 3:00pm (6 hours they expect me to wait). The person who took the appointment gave me a hint, If I call again after 9:30 she'll be able to give me a shorter time frame for when the inspector will show up. I got conformation of my extended

It is determined that the furnace is 10 years past its normal lifespan. They will send a second person later today to give an estimate for a new furnace.
