We are a family run waterproofing specialist company, owned and operated, since 1976 by A.J. DiElsi. We have one crew, one truck and start and finish one job at a time. We are completely insured with general liability and workman's compensation. There is no charge for estimates and we take no deposits on any job. You pay us upon completion of the job. We do not have salesmen. A.J. is the gentleman that comes out to deliver each estimate and he is on each job. We excel in impeccable workmanship, and the jobs are always left cleaner than when we arrived. We give a lifetime guarantee on our French Drains and it is transferable to each new homeowner. Please feel free to call with any questions 610-527-9444 or 610-409-0888, Additional phones: 610-960-1589. Or feel free to email us at : ajwaterproofing@verizon.net, you can also check us out on YouTube and our website, ajwaterproofing.com.

"QUICK, FRIENDLY, and CHEAP!! First, AJ called me within 30 seconds of me texting him asking for an estimate. I sent him a photo of our water leak issue and he immediately responded. He actually explained that we could probably handle the repair ourselves if we were up for it, instead of paying him or someone else. He then walked us through every step in detail and made sure we were comfortable with the directions. So in the end, it cost us $0 in labor and only a small amount for materials, and really demonstrated AJ's integrity and generosity!"

He was able to address the cause of the malfunction; much to our relief, as we thought we might have to have a new toilet installed or a much more complicated repair. Tom also came out to our home before the start of his official workday, to make sure that the issue was handled immediately. THANK YOU, TOM!!"

Horizon Services is the region’s largest and most well respected plumbing, heating and air conditioning company, with nearly 600 employees serving tens of thousands of homeowners throughout Delaware, Southeastern Pennsylvania, Southern New Jersey, and Northeastern Maryland. After a quarter of a century in business, Horizon Services remains fully committed to setting the industry standard for customer service, installation, and focusing on things that are important to busy homeowners: respect for their time, their home and their property; up-front pricing, and an unconditional 100% money back guarantee. Horizon Services is the Heating Company Your Friends and Neighbors Call to Keep Warm All Winter Long!

"I wouldn’t be writing this Review if one thing would have happened, TALK TO ME. Don’t place the answering service in the position of telling a Customer that the Supervisor has left for the day at 2.45p on a Thursday. Especially when the Horizon repairman had just fried our whole cooling system, including the thermostat!! What started with a bad fan motor in a new AC system that was only 3.5 years old in a $10,000 system, for which we had waited 4 days for the new motor to be installed. Add to that the fact that the repairman told me he would be at our home at 8.30a and didn’t arrive until 11.30a - after having to use a vacation day to wait at home for them to arrive. Then telling me this will be ‘quick’ all I have to do is switch out the motor by mounting it and plugging in the new one. Hours went by, nothing. He comes in to test the thermostat and it is non-responsive. He tells me to get new batteries, which I did. Then asks me, “these are new?” To which I say, ‘of course’ - you watched me take them out of the box. Then he goes out to his truck for the next 1.5hrs, supposedly speaks with his Supervisor and comes in and tells me that he has fried the system. I reply by saying I will be calling a senior person to speak with them. Called 4 times and never spoke with anyone. Each time I waited on hold for an extended period of time. Each time, I was then told by the answering service that someone would call and never did. Then at 2.45p I am told “everyone has left for the day” and no one would be calling. This was a Thursday, I had been home all day and no one would speak with me. We remain without an AC system, no plan, no calls - - nothing!!! If I could rate them a ZERO, I would,"
