Customer Testimonials

We have grown over the course of our 65-year history because of our dedicated employees and loyal customers. We are always grateful for the kind words of those who place their trust in us.


Recent major work on our hotel, in conjunction with our owners utility team, was excellent. The Schlosser team, led by Andy, were amazing and they replaced a key part of our utility supply with ZERO impact on our guests! Now that is SERVICE and SKILL, thanks from the Courtyard Newark at the University of Delaware!


“The two gentlemen that came were friendly and knowledgeable. They were also very professional and made me feel like they knew their stuff. It didn’t take them that long but my sink is working and so is my dishwasher so I’m beyond ecstatic. I can see why they have been in business as long as they have.”


“They were friendly and professional. I was told they would be here between 10-12. They were prompt, they unclogged my kitchen drain and cleaned up after. They were great.”


“First class service at a budget price. We had to install a gas line for an outdoor electrical generator. Estimate was accurate, complete with information on the type of piping and how it would be installed. Service was prompt, people were friendly, and the finished product blended very nicely with our home. One of the rare few companies we’ll be contacting again for our next project.”


“Thank you for setting up the HVAC service for us. It was super speedy. Your crew brought the contract out last week when they performed the service. They did a wonderful job. Thanks again, and as always, for your quick and quality service. You do a great job.”
