When you need AC heating or plumbing services, look no further than Horizon Services. For nearly 30 years, we’ve been the trusted name in plumbing heating, and air conditioning, offering an unmatched level of service at reasonable rates.

"Less than 5 years ago, I spent in excess of $10,000 to have a new unit installed with a 10 year warranty. I should have seen the red flags from the very beginning. The sales representative told us additional vents would be installed and when the installation crew showed up, that did not happen. Fast forward to the present and I am now on my 4th phone call for an appointment this season, 3 days so far of not being able to work as I waited for a technician to come diagnose the problem. The 3rd. tech came last night and indicated that the work the other tech did was not for the root of the problem. (I was told in front of witnesses that the work needed to be done, was not covered under warranty, would cost me $367 and would fix my issues)In fact, the 3rd tech only made the issue worse by leaving our attic return unscrewed and overfilling our unit with Freon that the 4th tech had to remove from our system. Upon leaving last night I was told that everything was corrected. Today - my home is slowly creeping up in temperature (presently 80 degrees inside, while set to 72). The company keeps trying to sell me a "maintenance plan" and I keep reiterating to EVERY one who pushes it that we have been getting tune ups/cleanings elsewhere and will only use them for warranty issues since we have had NOTHING but problems with them."

Wilmington, Newark, Middletown and Dover DE and Cecil County, MD areas Plumbing & Drain Cleaning Services. Professional, Friendly, & Knowledgeable Plumbers. Your plumbing system is one of the most important components of a properly functioning home or business. When your plumbing system is facing issues, who do you call? Whether you’re dealing with a toilet that won’t stop running or a faucet that won’t stop leaking, it’s important to turn to true plumbing professionals to ensure you’re getting the best service available. At Mr. Rooter® Plumbing, we offer honest and reliable plumbing repairs and services to the locals of Wilmington, Newark, Middletown and Dover DE and Cecil County, MD the surrounding areas.

"First, can I just comment on how professional Mr. Rooter was from the very first phone call to schedule service. Since it wasn't an emergency, they had me choose from selected "2 hour windows" where they were committed to arriving. They sent a text with a photo of my expected tech (what a great feature so you know for sure who is coming to your house, especially these days), and emails as reminders. Plus the tech (Zach) called when he was ready to come and asked me if the time was still ok with me. How convenient! He put little booties over his shoes each time he entered my home. He was clean in appearance and personable from the start. Truly very friendly and I felt comfortable having him in my home. Zach has 15+ years experience according to the little bio Mr. Rooter sent me ahead of time, and it shows. Jacob, his trainee with a few years experience, was on his way to becoming independent very soon. Just needing to learn the Mr. Rooter ropes. I wanted a kitchen sink sprayer installed. Love those handy things but never had one because for some reason my dishwasher's aerator was located in that same spot. Zach explained to me how things have changed over the years, showed me how the sprayer and hose would connect under my sink so that nothing would back up, and all in a manner that I actually understood! Then he and Jacob worked together very quickly to get my sprayer installed and and working. Who knew such a small thing could bring so much joy. While he was there, Zach asked if he could inspect my plumbing or if I had any other concerns. I mentioned my toilet made bubbling sounds for quite awhile. He said he would take a look. I thought maybe something was caught in the line. He inspected with a camera but told me he doubted that was the case as usually if there was an air pocket or something with the sewer, I would also hear bubbling in my shower and sink in the same bathroom, which I never have. After camera inspection was complete and nothing was in the line, and since my toilet was 22 years old, he suggested a new one might be in order since I didn't like plunging it. He told me he could install it at that time if I wanted it since it was in the window of time allotted for me and he didn't have another call to attend to right away, or he could come back at another convenient time, whichever I chose. (There is some sort of good discount to have work done in the same day, so that was a plus!) Well, he and Jacob had 2 styles (round or oval) of Kohler toilets to choose from on his truck, high efficiency (half-flush and full-flush) with "quiet-close" toilet seats included to boot. Those seats are awesome when you have kids who just slam everything down, ha. I think they had that toilet done within an hour from start to finish! BTW, this was written by the woman of the house, but Zach willingly spoke to my husband over the phone about the toilet while he was here, so I didn't feel any pressure to make a decision on my own. So now I am scheduling a time for Mr. Rooter to come and install a sink basin in my garage for dirty clean up jobs. Zach was able to figure out how everything would connect from my basement and inside bathroom to my garage. He also said he would do a full sewer inspection with his camera when that happens. Can't wait....really. They are knowledgeable, professional, respectable, and very nice too!"

Percolation Tests questions, answered by experts

Services test for allergens, mold, VOCs, and carbon monoxide levels to ensure a healthy indoor environment.

Depending on the size of your home, the inspection process could take a few hours or a few days. While inspecting your home, the asbestos specialist will take small sections of the potentially contaminated material. They will then send the sample to an accredited laboratory or the local health department for testing. 

The cost of asbestos testing depends on your location, the home's size, and the testing area's complexity. Plan to spend between $230 and $800 for testing. During testing and while handling potential asbestos, the specialist may wear protective gear, including gloves, overalls, appropriate footwear, and respiratory equipment.

Asbestos was commonly used in cloth wiring, but not all types of cloth wiring contain it. The age, condition, and appearance of the wiring can provide clues as to whether asbestos is present or not, but the only way to know for sure if the wiring has asbestos is to have it tested.

Costs range from $400 to $800, depending on the number of samples and property size. Larger or older properties may cost more.

You shouldn’t see a difference in your home’s value from your local property assessor if you have asbestos. Does asbestos affect home value when you are selling the home, though? If you are planning to sell the home, most jurisdictions require you to legally disclose the presence of asbestos to any buyer. Most buyers would have reservations about purchasing a home with asbestos, so they may offer less for the home. If you hire a pro to completely remove the asbestos, you do not have to disclose to buyers that the home once had asbestos.
