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,"

Here at Zoom Drain, we are best known for fast response times and our ability to provide focused solutions to drain & sewer problems. If you are having issues or planning for future maintenance, call us now at 610-628-3360 for a FREE on-site estimate. From sinks, toilets and tubs to main lines and sewers, our team of drain & sewer professionals are ready to provide you with fast, expert services.

"They truly live by the code of "you get what you paid for". The price was cheaper than expected (and they included a free estimate too). So ultimately, our slow bathtub drain was cleared. However, the technician had terrible housekeeping. After stripping the caulking around the overflow valve, they left the caulking pieces in the bathtub and told us to flush them down the drain (?!). They said the provided bio solution would clear the pieces just fine...but why do that when a trash can is less than a foot away?? Then, they did not offer to reseal the valve they just opened...just left a mess for us to pick up. As such, we will not be using them again next time...free estimate or not. If we wanted the bare minimum, we would have done it ourselves."

FAQs for septic tank service projects in King Of Prussia, PA

Yes, most states require septic tank installers to have a license, and for good reason. Hiring an unlicensed septic tank pro could lead to poor quality work, costly future expenses, and potential code violations. 

As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: 

  • The owner, principal, or relevant manager passed a criminal background check

  • Required to have applicable state and local licenses

  • Maintain an average star rating of 3.0 or better on our network, if they have at least one review

  • Paying to advertise their services

  • Meeting any other eligibility criteria required by Angi

Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.

The cost to replace a septic tank is $7,350 for the average homeowner. This cost can range, however, from $470 to $22,500, depending on several factors. Your house size is a significant factor in the overall cost, but other things like material type impact the final price tag. For example, installing a new septic tank in a one-bedroom house typically costs $500 to $900, whereas installing a new septic tank in a five or six-bedroom home is generally $1,200 to $1,600.

The cost of septic tank repair is $1,775 for the average homeowner. However, depending on a few elements, you might pay as little as $170 or as much as $6,100. Location, repair type, and tank material all determine the final cost. For example, replacing the septic tank filter can be as little as $200 to $300. However, repairing septic lines costs more, averaging around $1,500.

A septic tank can typically last 15 to 20 years on average, though your system's lifespan will vary depending on the type of septic system and the materials used. To help increase your septic tank's lifespan, schedule routine maintenance and do not flush items like cat litter, cigarette butts, or paper towels.

Repairing or replacing a septic tank is a job best left to a professional. Your septic tank is an essential part of your home, and if installed or repaired incorrectly, it could lead to significant problems. Things like polluted water, property damage, and health risks to your family could all happen as a result of an improper septic tank repair or installation.
