7 Siding Problems Every Homeowner Should Know

Maintaining your home’s exterior isn’t just about looks—your siding plays a big role in fortifying your property from the elements, too. Over time, though, siding can start to show signs of wear and tear. The key is understanding the common issues that can arise so you can catch them early and potentially avoid costly repairs and tacky-looking siding.

In this blog, Powell Exteriors KC’s siding experts will discuss the top seven siding problems every homeowner should know about, along with practical solutions to address them. Whether you have vinyl, wood, or fiber cement siding, this guide will provide valuable insights to keep your home’s exterior in prime condition.

1. Cracking or Splitting

Cracking or splitting is a common issue with siding, especially in places where the weather tends to swing between extremes. When temperatures change, materials like vinyl or wood expand and contract, which can eventually result in the formation of cracks or splits. Additionally, things like hail, falling branches, or even accidental bumps can also cause cracks to form.

Signs To Look For

• Visible cracks or splits in the siding panels
• Small chips or fractures, especially near the edges or corners
• Gaps between siding boards

Solutions to Cracks in Siding

To repair minor cracks in your siding, use a siding repair kit with color-matched caulk or patching compound to fill the gaps. For more extensive damage, it’s best to replace the damaged panels, particularly with materials like vinyl, where cracks can affect structural integrity.

2. Warping or Buckling

Warping or buckling typically occurs in vinyl or wood siding due to improper installation or exposure to excessive heat and moisture. When siding isn’t installed with enough room for expansion, it can warp as temperatures change. Warped siding can lead to water infiltration, which can cause further damage to your home’s foundation and structure.

Signs To Look For

• Siding panels that appear wavy or uneven
• Gaps between panels or siding pulling away from the house
• Signs of water damage or mold underneath the siding

Solutions to Warped and Buckled Siding

To prevent these siding issues, make sure it’s installed with enough space for expansion and contraction, and keep your attics and crawlspaces well-ventilated to reduce moisture that can cause warping. You’ll need to confirm this detail with the installation contractor.

If panels are severely warped, replacing them is often the best solution to avoid further damage.

3. Fading or Discoloration

Fading or discoloration is a common problem across vinyl or painted wood siding. Prolonged exposure to sunlight, harsh weather conditions, and pollution can cause the color to fade, making your home’s exterior look dull and worn out.

Signs To Look For

• Noticeable color fading or uneven discoloration
• Chalky residue on the surface (common with painted siding)
• Stains or streaks that won’t wash off

Solutions to Faded Siding

To restore the color of wood siding, repaint using high-quality, UV-resistant paint, as this particular product prevents future fading.

For vinyl siding, consider replacing any severely faded panels to keep a consistent look. You should also consider applying a UV-protective sealant to help minimize damage from sun exposure.

4. Mold, Mildew, and Algae Growth

Mold, mildew, and algae can grow on any siding, particularly in damp or shaded areas. These growths are not only unsightly but can also cause damage to your siding and pose health risks to you and your family.

Signs To Look For

• Green, black, or white spots on the siding surface
• A musty smell near the affected area
• Warping or soft spots in the siding

Solutions to Mold on Siding

To keep your siding free from mold, mildew, and algae, clean it annually with a mild detergent, water, and a soft brush or a pressure washer on a low setting. Make sure your gutters and downspouts are clear and positioned to direct water away from your home.

5. Pest Damage

Wood siding is particularly vulnerable to damage from pests like termites, carpenter ants, and woodpeckers. Even other siding types, such as fiber cement, can experience problems if pests find their way behind the siding.

Signs To Look For

• Small holes or gnaw marks on the siding
• Sawdust or wood shavings near the base of your home
• Hollow sounds when you tap on the siding

Solutions to Siding Infestation

Regularly inspect your siding for signs of pests and promptly address any issues you find. Seal gaps and holes to eliminate potential entry points, and if you suspect an infestation, consult a pest control professional for an expert assessment and treatment.

6. Water Infiltration

While not particularly common, water infiltration is still a problem to watch out for. It occurs when siding is extremely damaged or improperly installed, allowing water to seep behind the panels.

Signs To Look For

• Water stains or discoloration on interior walls
• Soft or rotting wood near windows, doors, or corners
• Peeling paint or wallpaper inside your home

Solutions to Siding Water Damage

Regularly check your siding for damage or gaps, and use high-quality caulk to seal any cracks or openings. Ensure proper flashing around windows, doors, and other openings to keep water away from your home. If you notice any water damage, replace the affected siding to prevent further issues.

7. Loose or Missing Panels

Loose or missing panels are often caused by strong winds, impact damage, or improper installation. They detract from your home’s appearance and expose the underlying structure to the elements.

Signs To Look For

• Siding panels that rattle or move when touched
• Visible gaps or missing sections
• Drafts or increased energy bills, indicating a lack of insulation

Solutions to Siding Panel Damage

To fix loose siding panels, reattach them with nails or clips designed for your specific siding type. When you replace any missing panels, you’ll also want to check for any underlying damage that may have occurred due to the loose or missing siding.
