A selection of 212 homeowner reviews:
“Their customer service, quality of work, politeness, promptness, and follow-up are second to none. Within the next few weeks I will need some plumbing work done. Henderson will be my only call—the most honest service company I have ever dealt with.”
“We had a pipe burst during one of the coldest winters on record in Pennsylvania. We contacted them, and a plumber was dispatched within half an hour. He arrived, identified the issue, and fixed the problem in record time. Great service—A+.”
“Henderson Plumbing staff were very good at communicating the options we had for a shower replacement. The workers were very professional as was the quality of the work. We are very pleased with our new shower and would highly recommend Henderson Plumbing.”
“Wm. Henderson is an honest, fair, quality organization.”
“We had WM Henderson do the plumbing for a new bathroom in our house. They worked very well with me (I did the carpentry) and helped make the permitting process seamless. Several other area companies didn't want the job because it was 'too small' (rough in, then install a toilet and pedestal sink), so I was pleased to find a company that did a small job very well and with good customer service.”
“Always punctual, courteous, and skillful.”
“Wm. Henderson did fine—no problem.”
“They are very responsive, and they come quickly. The work they did was plumbing, and recently, they worked on our air conditioner. The plumbing was done as an emergency call at night when we had a backup. They do air conditioner maintenance, and now we're going to have an installation soon. I would say they're an A grade.”
“They're thorough. They come in, they do the work, and they don't rush out. They stay a little bit extra to make sure everything is right and that I understand what's going on. They fixed my central air unit. They had actually done all my plumbing, too, and they did good work on the plumbing as well. I would give them an A grade.”
“I found that Wm. Henderson was knowledgeable and straightforward. We had a water heater that went out, and they came to fix it literally within the next day. I chose them because of a recommendation by a neighbor. I can give them an A.”
