Keep Your Home Mold Free This Summer

Hot weather is on the horizon and it won’t be long before we begin complaining about the humidity. I don’t mind the heat, but like most, the sticky moisture that comes along with it can be a real bummer in the summer.

A lot of homeowners combat humidity by using air conditioners in their houses, 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 your 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.

A Vinyl Siding Conundrum

A reader recently wrote to me about a problem with her vinyl siding. The siding, which was only a few years old, had warped and started looking “wrinkled”, as she described it. At first, the reader thought it might be from direct sun exposure, but the wrinkling became visible all over the house, even in shady spots. What was she to do?

Warping is a fairly common problem with vinyl siding and it has nothing to do with the sun. The issue is actually called “oil canning” or “stress buckling” and it happens when the siding isn’t installed properly.

All homes are made of natural materials such as wood, which expand and contract with seasonal changes. People love vinyl siding because it’s very low maintenance and offers fantastic curb appeal, but a DIY or inexperienced install can actually make a house look much worse, even with very new siding. 

Every house needs to expand and contract. While it might seem logical to nail vinyl siding tightly to make sure it doesn’t come loose, doing so will actually cause the panel to buckle because it can’t expand and contract with the house. That’s why most vinyl siding panels come with longer nail slots instead of small holes. It gives everything room to move and shift. 

Another possible siding installation pitfall is leaving too much overlap between panels. While you might think this creates a stronger bond, it actually restricts movement, causing the siding to stretch and then buckle in the same way.

Back to my reader’s question. Is there ever a time when the sun might cause siding to warp? The answer is not really, although I have seen damage from sunlight reflecting off an adjacent window. The only other thing that could cause an issue is your gas grill, so keep it far away from the house. 

Once oil canning happens, the siding has to be replaced. Because the issue is installation, the product’s warranty is worthless and the manufacturer isn’t going to be responsible for the defect. While removing panels is pretty straightforward, it can be tough to get a color match if the siding is a bit older. 

These are all the reasons why it’s so important to work with a contractor who knows what he or she is doing. If you’re going to tackle this job on your own, make sure you do your research and know all the common mistakes that can be made. You don’t want all that hard work to result in a home aesthetic that’s anything less than perfect.

Do You Need Your Roof Cleaned?

Do you see black, streaky stains on your roof? Is mold or moss starting to spread across your shingles? If these issues are creeping up on you, a roof cleaning might be just what you need to maintain the health and aesthetic of your home. 

Stains on a roof are generally algae, which gets carried by wind or birds from roof to roof, and may not be visible until there is enough moisture, heat, and humidity for it to grow and spread. Homes that aren’t properly insulated and ventilated are also susceptible to the problem because they retain moisture a lot more than houses with proper airflow.  

If you’re worried that your stained or moss-covered roof is doomed, don’t panic just yet. While too much moisture is a major problem that needs to be dealt with, algae that is deposited externally from the elements can be removed with a simple cleaning. That being said, the first thing you want to do is find out if your issue is cosmetic or something more serious. 

Ideally, I recommend that a homeowner gets a roof inspection at least once a year and the late spring is one of the best times to do it. During an inspection, a roofing professional will check the entire surface area for shingle deterioration or damage, cracking around the flashing, and will also ensure that water is draining properly through the gutters and downspouts. Something as simple as debris build-up can void the warranty of a roof, so it’s well worth having an expert come and take a look. They will be able to tell you if your stains are something that can be taken care of with simple cleaning or if there is a bigger picture issue.

To get rid of discoloration, mold, and mildew, we use a professional roof cleaner that adheres to the growth but doesn’t harm the roof or any vegetation below it. A roof cleaning takes a few hours depending on the size of the area and one application does the job without the need for pressure washing which can damage the shingles. 

Working on a roof is a very dangerous job and I never recommend for a homeowner to do a task like this themselves unless they are very comfortable on a ladder and with heights. No home maintenance task is worth a trip to the emergency room.
