Get matched with top water treatment & purification system repair or service pros in Horsham, PA

"They were very nice and explained everything. I have them back every year to service the water softener and change the appropriate filters on the reverse osmosis water filter system. They always share what they are doing and seem ok if I did it myself, which is one of a few reasons I keep having them come back. Yes, more expensive then DIY, but the fact that they know what they are doing and are honest is more then enough for me to have them doing the work."

"Joe was responsive, showed up on time, and made sure the installation was done right. Very happy with my water softener and treatment system."

"Steve replaced our water heater, his service was quick, he was helpful explaining all the details and had a great personality as a whole."

"The team of four guys worked very hard over the course of two days to do all of the above work.  They were professional and explained everything to us.  The used tarps and cleaned up after finishing each day.  In addition, two different supervisors stopped by multiple times over the two days to check in on the progress of the work. <br /> We were extremely pleased by the excellent work and customer service.  We had been in our home for about a year and the air conditioning has never worked as well as it does now. <br /> We would highly recommend this company! <br />"

"Quickly. The plumber was here at the scheduled time and completed the repair within minutes. It's the second time we used the services of Valdel Plumbing. Another fellow installed a kitchen sink and we would highly recommend this service for other households."
