Why Upper Darby Homes Need an Experienced Local Plumber

Upper Darby is a densely developed Delaware County township where a large share of homes were built in the early to mid-20th century. Cast iron sewer lines, galvanized pipes, and older fixtures are common throughout the area. When one component begins to fail in a system with decades of use behind it, the problem can accelerate quickly if it isn’t caught by someone who knows what to look for.

The area’s clay-heavy soil shifts seasonally, placing ongoing stress on underground sewer and drain lines. Root intrusion and cracked lines are recurring issues for older properties. Winter temperatures that drop below freezing create real risk of frozen and burst pipes, particularly in homes where pipes run through uninsulated crawl spaces or exterior walls. Hard water deposits compound the problem over decades, restricting flow and shortening fixture and appliance life. McLoughlin Service Experts has worked through these exact conditions in Upper Darby’s homes since 1965.

What to Expect When You Call for Plumbing Service

Knowing what each step looks like takes some of the stress out of an unexpected plumbing problem. Here’s how a typical service call works.

First Contact
Live customer service is available 24/7. Whether you need emergency plumbing services or want to schedule a routine appointment, you’ll reach a real person who can dispatch a plumber or find the next available time.

FAQs We’ve Got Answers to Your Plumbing Services Questions

Yes! If you have an emergency plumbing problem, we can respond promptly and make any repairs needed.
It may be difficult to prevent leaks entirely, but you do have options for minimizing risk. Seals and valves are a common source of leaks, so keeping up with maintenance can minimize the risk. Letting professional plumbers handle projects like repair and repiping will also ensure the entire system is as tightly sealed as possible.
The total cost will depend on where the leak is in your home as well as the extent of the damage. A minor, dripping leak is more easily resolved than severe damage to the water main.
With all the locations where water is used in your home, there are a lot of areas you could uncover a leak.
Leaks can be triggered by a variety of plumbing issues. They are usually spotted:
- On water supply lines and connections underneath a sink
- In washing machines, especially old units
- In hot- and cold-water hoses linked to your washing machine
If you notice the signs of a leak, we can help. We back all of our work with a Service Experts Guarantee for a year.*
If you believe you have a leak but can’t see the signs, check your water meter:
- Make sure no water is being used inside or outside your home.
- Check the leak indicator on your water meter. The indicator is commonly a triangular dial or miniature silver wheel. If the dial is spinning, you probably have a leak.
We can find the origin of the leak and get it repaired before you spend more money or potentially damage your home.
