A Crack in the Ceiling? Here’s When to Worry

You’re sitting in the living room, you happen to look up, and there it is… a crack in the ceiling. Maybe it’s brand-new, or maybe you’re just noticing it for the first time. Either way, it’s natural to wonder whether your ceiling needs a little patching or your house is trying to tell you something.

The good news is that most ceiling cracks aren’t a reason to panic. Houses move a little over time. Wood expands and contracts, drywall settles, and changes in temperature and humidity can cause small cracks to appear.

Still, some cracks deserve a closer look. The trick is to pay attention not only to the crack itself, but also to what’s happening around it.

First, Look at the Pattern

A thin, fairly straight crack often follows the seam between two sheets of drywall. The tape or joint compound covering that seam may have loosened as the house moved. If the ceiling is otherwise flat, dry and solid, this is usually a cosmetic repair.

Cracks also show up where the ceiling meets an interior wall. Sometimes this is caused by seasonal movement in the roof trusses. You may notice the gap more during the winter and less during warmer months. It can look alarming, but it doesn’t necessarily mean the roof is failing.

Older plaster ceilings tend to develop their own collection of fine cracks. A few small, stable cracks may simply be part of the home’s age and character. Loose, sagging or bulging plaster is a different story and should be checked.

Here’s a good rule of thumb: a small crack that hasn’t changed in years is usually less concerning than one that appeared overnight or keeps getting longer.

Take a Look Around

Before grabbing the spackle, give the whole area a quick inspection. Is the ceiling flat and firm? Do you see a stain, bubbling paint or peeling? Does anything feel damp or soft? Has the crack grown? Are doors suddenly sticking, or are new cracks showing up on nearby walls?

One little crack may not tell you much. Several changes happening together can.

For example, if you have ceiling cracks along with sloping floors, sticking doors or cracks around windows, there may be movement elsewhere in the house. That doesn’t automatically mean you have a major structural problem, so don’t assume the worst. It does mean you should have someone take a look before simply covering everything with paint.

Don’t Ignore Water Stains

If there’s discoloration around the crack, water moves to the top of the suspect list. The source could be a roof leak, damaged flashing, an upstairs bathroom, a plumbing line or even condensation around ductwork.

Remember, the stain isn’t always directly below the leak. Water can travel along a pipe or ceiling joist before it finally finds a place to show itself. A brown ring, musty smell or bubbling paint should be investigated even if it feels dry today. Some leaks only appear during a hard rain, when snow melts or when someone uses a particular sink, shower or bathtub.

If the ceiling is sagging, bulging or holding water, keep everyone, including your pets, out of the room. Don’t stand underneath it, and don’t poke the bulge with a broomstick. Wet drywall can be surprisingly heavy and may come down without much warning. Water near a light fixture can also create an electrical hazard.

When Should You Call Someone?

It’s time to bring in a qualified contractor, home inspector or structural engineer if:

• The ceiling is sagging, bowing or pulling away

• A crack appeared suddenly or is growing quickly

• The crack runs across the ceiling and continues down a wall

• Several new cracks appear around the same time

• The drywall feels soft or the plaster is coming loose

• You see water stains, dampness or active dripping

• The damage appeared after a storm, roof impact or heavy snow

• Cracks are accompanied by uneven floors or sticking doors

If you’re not sure whether a crack is changing, take a picture with a ruler next to it and write down the date. Check it again in a few weeks. A couple of small pencil marks at the ends can also help you tell whether it’s getting longer. Of course, monitoring is only appropriate when the ceiling is dry and solid. If it’s wet, sagging or dropping material, don’t wait.

Most ceiling cracks turn out to be ordinary wear and tear. The important thing is to slow down, look at the whole picture and use a little common sense. A coat of paint can hide a crack, but it can’t stop a leak or correct movement behind the ceiling.

And if your gut tells you something doesn’t look right, make the call. It’s usually easier, and less expensive, to check a small problem today than repair a much bigger one tomorrow.

Dehumidify Your Home For Cool, Clean Air

Summer weather is nearly upon us and it won’t be long before we start to complain to each other about the humidity. For the most part, I enjoy the heat, but the hot, sticky moisture that comes along with it can be a real drag this time of year. 

Most people combat humidity by using air conditioners, and while they can reduce the moisture in the air to some degree, this is by no means their primary function. An air conditioner works by sucking the air from your home, cooling it, and blowing it back into the house. That process does reduce the humidity slightly, but pairing your air conditioner with a dehumidifier is the best way to cool down your home so you can sleep more comfortably at night.

A dehumidifier works by pulling the moisture out of the air and storing the excess water in a holding tank. Many people keep dehumidifiers in their basement all year long to control the dampness that can often be felt in these underground areas. This is a great idea because controlling the humidity in the dampest part of your home will very likely help to regulate the rest of the house.  One way to know if you’re house is holding a lot of moisture is to purchase a simple five-dollar humidity gauge from the local hardware store. Ideally, you want the humidity to be under 50%. If it’s higher, you might want to consider using a dehumidifier in the main part of your home, especially on hot summer days and in areas where you spend the most time.

In addition to cooling the air and decreasing moisture, running a dehumidifier during the hottest parts of the hottest days can also prevent mold and mildew growth, eliminate musty odors in the home, and prevent old pipes from sweating. Plus, you can use the water collected in the tank to give your outdoor plants a good drink! Dehumidifiers generally run on about half the energy of an air conditioning unit, so as long as you don’t run them all day, using one shouldn’t affect your energy bill. Just be sure to keep windows and doors closed when you run your unit, and only switch the power on during the most humid time of the day, or when the air is above 50 percent humidity.

Be aware that dehumidifiers by nature are drying, so try not to run them while you’re occupying the room over a long period of time, like when you’re sleeping at night. Also, be careful about using dehumidifiers in conjunction with an attic fan. I see people do this all the time and they unintentionally throw the excess moisture from their home or basement up into their attic, where it has no place to escape.

 If you’re thinking that a dehumidifier might be a good solution for you, they come in different sizes and can be used for residential or commercial purposes. Generally, a unit will come in 25, 30 and 40-pint models, and on average a 25-pint unit will be sufficient to operate in a 1,000 square foot area.

 Finally, if you have a dehumidifier, please be sure to keep the filter clean. Dust, dirt, and debris can get caught in the filter, preventing air from flowing freely and potentially circulating mold spores throughout the home. A simple wipe down with a damp cloth and spray bottle will do the trick to keep you breathing freely and ensure a longer life for your appliance.
