"hands down the best in northwest NJ! Seidel electric was referred to me by a coworker with raving reviews when I was looking to put a generator into my newly purchased home. The owner (Steven) sat down in my kitchen for a long and thought out conversation and ended up doing a wonderful job for way less than the competition. Most recently my transfer switch was blown out by a power surge during a brown out. Steven and one of his electricians came out on their off time to make sure his customer was taken care of. They do great work, for great prices, and have even better customer service."

Energy Aide, Div. of Coastal Windows/Doors/Exteriors
ENERGY AIDE a division of COASTAL WINDOWS DOORS & EXTERIORS has been serving Monmouth, Ocean and Middlesex counties in New Jersey for over 40 years. We are the premier home improvement contractor for ALL the energy efficient products and services you may need . Let us show you how blown in cellulose insulation in your attic and non masonry walls will help you be more comfortable in your home while reducing your energy bills for heating and air conditioning. In addition to blown in cellulose insulation we offer energy efficient windows, doors and siding with lifetime guarantees (products & workmanship) to make your home the envy of all your neighbors .
"Do not use Energy Aide for replacement windows! The rep that came out to measure my windows measured incorrectly by one inch. He assured me that they could build out that one inch space and that it wouldn't be a problem. The piece of wood they placed in the space below every window has rotted out. In addition they did not seal and insulate around the windows. So every winter I have to jam paper towel into the tracks on the sides of the windows to try to keep the cold air and wind to come through the windows. I had siding replaced and the contractor showed me this shoddy work. I have a lifetime guarantee on the windows from Energy Aide that states. "Energy Aide guarantees all workmanship for as long as you own your home! All guarantee work is 100% free covering both the cost of labor and materials. We will repair or replace anything found incorrect due to the original installation." I called and the owner refused to fix the horrible installation workmanship! Horrible service! Do not use Energy Aide for replacement windows. Not only did they install the windows improperly, they DO NOT back up their work! I am now replacing my windows with Anderson with a professionainstaller."
