Mold on Siding, Not Just Unsightly

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 1950s, it became a favorite aluminum replacement due to 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 area that’s most susceptible because it gets the least amount of sun exposure. 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 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. Any of this debris will quite literally make a meal for spores to feast on. 

So what can you do to keep mold 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 bleach-containing materials to not harm the vegetation surrounding your home. 

Once your house is cleaned, 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.

Warped Siding is a Common Problem

A question I get from readers time and time again is about vinyl siding that looks “wrinkled” even when it’s new. Many people think warped siding is an environmental problem and that too much sun and heat or even the contrasting winter cold is what’s creating the damage. Little do they know that warping has very little to do with the weather and a whole lot to do with how it’s put on the home.

Let’s start with the real name of the problem. Siding that is wrinkling or warping 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 “breathe” 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.

Siding Trends for 2022

One of the best ways to instantly transform your home is with siding. As a durable, easy to clean, and highly customizable option, it’s no wonder why siding, and vinyl, in particular, is such a popular choice for savvy homeowners. Let’s have a look at what trends are popular now and what we’ll be sure to see in the years to come. 

Bold and Beautiful

While white will always be a classic color, darker shades of maroon, navy, green, gray, and brown are making a serious comeback. Popular in the 1980s, the dark look is being seen more and more in new construction and homeowners are making the choice to go bold with a deeper shade. Consider pairing a dark hue with a lighter trim for a nice contrast that will make the home stand out. 

Black and White

If a dark house isn’t your cup of tea, you might want to try the reverse. We’re seeing more and more light and white homes embrace dark color trims, especially black and charcoal. If you prefer to stick to a neutral siding tone, darker accents around doors, windows, soffits, and porch banisters can still add personality without being over the top. 

Texture

Another trend that’s gaining popularity is a textural finish on vinyl siding. Flat, smooth panels are making room for everything from wood shakes to stone and stucco finishes. Many people opt to use a designer finish in certain areas of the house to distinguish certain architectural features which add character and give a more polished, upscale look. 

Shading

While contrast certainly makes a statement, many people are opting to stick to one color family for a more subtle dimension. Plan to see siding, trim, and roofing in various shades of grays, browns, and greens, which give a home a warmer contrast that feels subdued yet polished. 

Vertical

Finally, now might be the time to consider vertical vinyl siding. This is a fantastic approach that gives a home height and it can be used in conjunction with horizontal siding for a unique look. Vertical siding is also easy to clean and slightly less resistant to mold growing in the seams. It’s slightly more expensive to install, so keep that in mind if you’re considering this look.

Speaking of cost, one last thing to consider is the cost of materials these days. Remodeling projects are in high demand and so too are supplies. Between manufacturing, transportation, and logistics, your project might take a little longer and cost a little more than you would expect. Ask your contractor about any potential delays or price increases while you’re getting your quotes to be sure your project runs as smoothly as it should.
