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.

Moldy Siding? Don't Leave It Alone

Here in this part of Connecticut and in most of New England, vinyl siding is a popular cladding option for many homeowners. Starting in the 1950’s, it became a favorite aluminum replacement for its low maintenance and high durability. With a wide variety of colors and textures, it continues to be a fantastic option, offering personalized style without having to worry about sanding, painting, or major maintenance. 

While vinyl siding is beneficial in so many ways, one complaint is the potential for mold growth, often on the north side of a home. To be clear, mold can grow anywhere, but the north side is the most susceptible because it gets the least amount of sun exposure. Mold, mildew and fungus thrive in dark, damp places, which is why the north side of any home is generally the most vulnerable. Constant shade, high vegetation, or anything that stops a house from getting regular sunlight is an invitation for mold to grow in that area, whether it’s clad in vinyl or not.

In addition to a lack of sunlight, excess moisture is another mold inhibitor. The cause could be as simple as trapped rainwater that’s unable to drain properly. Another possible issue could be a faulty drain pipe or a gutter that’s dripping on the siding, causing constant dampness. Either way, a moisture problem is something you’ll definitely want to deal with as the water will continue to feed the mold, which will then spread. 

Another reason for mold growth on siding is a build-up of dirt, which is actually a food source for all different types of fungus. Something as simple as a dryer vent can cause dirt and dander to stick to the siding. Tree sap is also common and can be tough to remove. Homes on high traffic roads tend to get dirty more easily as well. All of these causes quite literally make a meal for mold spores to feast on.

So what can you do to keep mildew at bay and ensure your vinyl siding looks great for years to come? Assessing your sunlight and moisture exposure is key, but what if you don’t want to cut down a tree or you happen to live in an area where moisture is a problem? A professional will be able to inspect your siding and treat the mold using a cleaner and blocker that removes spores and keeps them from coming back. It’s important to use a specially designed cleaner that is strong enough to tackle mold but not too harsh that it will damage the house. You also want to be careful not to use any bleach-containing materials so as not to harm the vegetation surrounding your home. 

Once your house is cleaned, be sure to maintain your vinyl siding by assessing your home for moisture, treating leaks promptly, and keeping your gutters clear and free of debris. An annual inspection will help to ensure that any problems are dealt with promptly so they don’t get out of control.

Decorate Safely This Holiday Season

Now is the time of year when we begin to get into the holiday spirit. From trimming the tree to decorating the house, adornments of any kind are a sure fire way to feel festive, even in this current COVID environment. But for all the fun, holiday decorating should be taken seriously to ensure that no one gets injured and you’re not at risk for a potential fire. Here are some things to consider. 

Ladder Safety

When hanging lights and decorations outside of your home, be sure to use a safe ladder that sits on level ground and can hold your weight properly. Always have someone with you to act as a spotter and don’t ever attempt to hang décor that’s out of your reach.

Circuit Breaker

If you’re going for the Griswold effect, make sure you read the labels on your lights to ensure you have the right wattage levels and that they are certified for outdoor use. The last thing you want to do is overload your circuits and end up in the dark or with a nasty shock. Inspect older lights for bad bulbs and stripped wires, and replace problem strands with new ones. I recommend LED lights, which run cooler, are more energy efficient and will have less of an impact on your power bill. Make sure all your lights are plugged into ground-fault circuit interrupters (GFCIs), which can be found at the local hardware store.

Avoid Siding Damage

When hanging heavy décor such as wreaths, do not drill holes into your vinyl siding. Once the wreaths have been removed, the holes will enable water to get underneath the material, causing potential mold, mildew, and leaks. Instead, purchase some heavy-duty siding hooks, which can be found at any home goods store this time of year. They will be able to withstand the weight of your decorations without damaging your home.

Roof Caution

If you’re putting Santa and his sleigh to top of your roof, make sure to secure him and any other inflatables tightly to withstand any wind and bad weather. Also, use the opportunity to inspect your roof for any missing or damaged shingles. Finally, take a look at your gutters to make sure they are free from debris and ready for the winter. Roof and gutter wear can cause leaks during the snow season, so it’s better to get them repaired now before it’s too late.

One Last Tip

Speaking of preparing for the snow, here’s one last tip. Grab some reflecting stakes from the hardware store and place them along the perimeter of your yard where it meets the road and your driveway. These place markers will help snow plowers see where your lawn begins and can help them navigate their snow removal without tearing up your grass.
