We fabricate and install custom ventilation solutions (sheet metal ductwork) when installing a new unit to meet code requirements and while performing HVAC work in new builds. This guarantees that the work is done properly and can reduce your expenses.
We replace hot water heaters, including the latest tankless models, provide new water and sewer connections when required and address any plumbing issues you encounter, from leaky pipes to toilets that continuously run. We also replace any needed fixtures.
Back in May 1967, Augustine ""Augie"" Calfo and Donald ""Slim"" Haight started Calfo & Haight, Inc. In the beginning, there were three employees: Augie, Slim, and Gerry Calfo (Augie's wife). Gerry handled the phones and bookkeeping. As demand grew, so did the number of employees. Over time, Augie's children entered the family business, with two of them, Nick and Dawn, working alongside. Augie's oldest grandson also joined the plumbing trade and joined the team.
We take pride for our honesty and friendliness with clients. We are proud that we still have long-standing relationships with some of our original customers.
Even though Augie and Slim have left us, Nick, Gerry, and Dawn continue the legacy. We employ long-time plumbing and HVAC technicians handling the fieldwork. All of our staff are treated like family, which is why they stay with us for many years.

Recommended Customer Reviews
This is the first time I have EVER written such a negative scathing review of a contractor, but I am doing it because 1) they are supposedly a 5-star plumber and 2) they totally diss'ed me this morning. I contacted them almost two weeks ago, but they could not respond before I went away, so we scheduled their visit to my property for today. They contacted me yesterday to confirm the appointment that we made about 10 days ago. I was impressed, and I thought I had finally found a reliable plumber to take care of my 18 rental units around north Wilmington, DE. We discussed the appointment and I was told that they would be there at 7:30 AM. That's a little early for me but since I was the first call for the day, I set the alarm for 6:00 A. I arrived at the location at 7:20 AM and proceeded to prepare the work site (i.e. Open basement Bilco doors, hook up garden hose to wash off their equipment after clearing the sewer line, etc). I then sat in my car and waited, and waited. Finally, at 8:00 AM I called their office and after being told maybe they stopped for coffee, I reminded the lady that it doesn't take 1/2 hour to get coffee. She put me on hold for about 1 minute then came back on to tell me that one of their plumbers didn't show up for work today and could we reschedule the appointment for tomorrow... Needless to say I cancelled the service call and told them that I need a company that's more reliable than them. Fortunately, it wasn't an emergency problem, but be forewarned that this plumbing company is totally unreliable and must fall apart when JUST one plumber doesn't show up for work. Since it's impossible to give negative stars, I had to give it one which is 5 times better than they deserve.....
John S.I was in need of HVAC services for my business and had called locally for several quotes. Calfo & Haight responded immediately (first). Their quote was detailed and fairly priced. Their representatives professionalism gave me confidence in the organization as a whole and I chose them. Their crew was incredibly professional and work quickly and respectfully. The job was done perfectly, quickly and on schedule. I've since used them again and received the same level of service. They know customer service and quality. These guys are reals pro's and they ""get it"". In fact, a friend of mine who is in the HVAC business referred me to these guys... That says a lot.
