Water Stains on the Ceiling: What’s Going On?

leak-in-pipeIt’s not always easy to know where something is amiss with your household plumbing system. Sure, when you suddenly have no water coming out of your taps or the toilet starts to overflow, you’ll be certain you have a problem. (Thankfully, you can reach us 24 hours a day for emergency plumbing service.) But leaks and corrosion in plumbing can often go undetected for weeks, months, or even years before people notice them—and by that time serious damage and massive water waste will already have occurred.

We’re going to take a look at one sign of plumbing trouble you might see in your house; it’s a common one, the stain on the ceiling. When you suspect it’s time for plumbing repairs in Pomona, CA, give us a holler and we’ll be there to help out.

What Water Stains on the Ceiling May Mean

Let’s try to understand why this is happening and find out the source, which will make repairs go smoother.

First, if you live in a two-story house, what room is directly above where the stain is appearing? If it’s a bathroom, you almost certainly have a pipe leak in the bathroom plumbing. But the location of the stain won’t help you know exactly where the leak is coming from; the water might be running along wood beams or through insulation. It requires leak detection services from licensed plumbers. They can pinpoint the precise location and then go up through the drywall to repair the problem with minimum disruption to the building materials. Please don’t let amateurs attempt to fix a leak based just on a ceiling stain.

We’ve often found that bad pipe installation is the source of the ceiling spots. The caulking going bad on bathroom plumbing pipes is one reason for these leaks. In these cases, our plumbers will have to do some repiping to help keep the plumbing system in good shape going forward. A quick patch isn’t always the best solution.

If you live in a one-story home, or the only space above the water stain is the roof, then the problem may be with the roof itself because of rain and snow, and you’ll need a roofing contractor. It still might be a plumbing issue, however, depending on the layout of the plumbing in your home.

Here’s something to keep in mind: the water stain isn’t the real problem. We know it looks ugly, but the first job is to find out why there is moisture creating the stain. Fixing the stain is actually pretty easy once the pipe leak or other source of water is dealt with.

Now the worst thing you can do—and unfortunately this occurs often with homeowners—is just to ignore the stain. “Huh, cost of living in a home, right? Depreciation and all.” Don’t let yourself think this way! You’ll eventually end up with a ceiling falling apart bit by bit and massive unseen damage occurring the wood and insulation. The worst-case-scenario is part of the floor above collapses. Make sure you heed the warning and call on professionals when you notice a stain on the ceiling.
