Homeowner Reviews

“#1 plumbing company in Northern Virginia.”

“100 percent satisfied with their work. They were on time. They fixed my air conditioner quickly and did not 'over repair.' This reflected their high ratings online. I immediately signed up for their annual heating/cooling inspection.”

“The service individual wore shoe covers to protect my carpet, listened to my concerns/problems, and quickly went to work. He thoroughly explained what the problem had been, what steps he took to repair, and asked for any questions/concerns I might have before departing. Great service!”

“We are so thankful that Long's is a part of this program, as they were prompt, efficient, knowledgeable, and friendly.”
