4 Signs You Need Replacement Siding

Siding is one of the most essential features of your home’s exterior. Not only does it give your home style and appeal, but it also has the lofty job of protecting it from the elements.

That’s why it’s important to keep an eye on your siding’s health. Once siding starts to break down, it can no longer effectively protect the underlying framing and insulation. And that leads to all kinds of issues, like mildew, wood rot, and pest infestations. Yikes!  

Luckily, your siding will start dropping hints when it’s ready to be replaced. Here are some common warning signs that the time has come for replacement siding:

Mold

Mold is always a bad sign, no matter where in your house it pops up. Siding is no exception. When mildew grows on siding, it looks like gray or greenish stains. It may appear on all exterior walls of your home, or just in certain areas.

While mold doesn’t necessarily mean you need brand new siding (you may be able to powerwash it or scrub it off), it’s certainly a sign that your siding needs some TLC. However, if the mold is extensive or was left to grow for a long period of time, your siding may be damaged and need replacement. Especially if you have wood siding, which is more delicate and prone to weather damage than vinyl.

Warping

Healthy siding will lay flush against the exterior walls of your home, with each board stacked neatly atop the next. They should like the crisp horizontal lines on a piece of notebook paper. If your siding is instead bowing or arching away from the wall, that’s a serious problem. It usually means the siding has suffered from water damage, pest activity, or poor installation. Although warping is most common for wood siding, homeowners are often surprised that it can happen to vinyl siding as well.

Gaps and cracks 

Just like holes in a suit of armour, siding with visible gaps or cracks can’t protect what lies underneath. Water from passing rainstorms and melting snow will eventually make their way through the gaps. Insects and rodents may decide to seek warmth and refuge beneath your siding. Cracked siding can even lead to drafts, which make your home less comfortable and energy efficient. As you can see, siding gaps can lead to a whole trove of problems!

Discoloration

Siding is routinely exposed to wind, rain, hail, sunlight, and anything else mother nature can throw at it. All of that exposure will eventually take a toll on your siding. Each type of siding will react differently to the elements. For wood siding, you may see peeling paint like the image below. However, vinyl siding isn't painted because it's manufactured in a specific color. Instead, it fades in the sun, so certain areas of your home may look lighter or darker than others.

So, do any of these red flags sound familiar? If so, your home is an excellent candidate for replacement siding. Fortunately, there are lots of exterior remodeling companies out there that can help you upgrade your siding. Just be sure to check out their reviews before you let them anywhere near your house!
