One of the biggest returns on investment any homeowner can experience when upgrading their house is through the wonders of vinyl siding. Aside from adding instant durability, versatility, and enhanced curb appeal to your home, vinyl siding requires minimal maintenance to preserve its integrity, providing your house with added protection and aesthetic appeal for many years.

However, as with all components of housing materials, it is inevitable that your vinyl siding will ultimately endure some wear and tear, especially after enduring several Minnesotan winters. But how do you know when it’s officially time to repair your home’s vinyl siding or replace it? Our siding experts at Window World Twin Cities will tell you when.

Vinyl Siding Damage That Requires Repair

Here are a few prevalent signs that your vinyl siding desperately needs some repair work.

Mold & Mildew

One of the common forms of vinyl siding deterioration is the growth of mold or mildew. Therefore, any signs of white, black, or grey spots that appear to be growing more frequently by the week are a sure sign that moisture buildup is impacting the longevity and integrity of your vinyl siding.

While washing off any patches of mold or mildew before it gets out of hand can spare you from having to get your siding repaired, the water you’re using could further infiltrate the insulation of your siding and walls, causing the moisture to increase and expand. The longer you leave mold or mildew unattended, the quicker you’ll start to see your vinyl siding rot.

Chips, Cracks, & Dents

While you might think a few dents in your vinyl siding are nothing to worry about, the fact is that the more chips, cracks, or dents your vinyl siding accumulates, the weaker its structural integrity becomes.

Any gap or holes endured by your vinyl siding can lead to a variety of housing issues, ranging from:

●        Leaks or flooding

●        Insulation inefficiencies

●        Possible critter or insect infestation

●        Higher energy and utility bills

●        Reduced curb appeal and home value

The bottom line is that no amount or size of chip, crack, or dent on your vinyl siding is too insignificant to consider getting it repaired.

Infestation Issues

The longer you’ve gone without repairing or replacing your home’s vinyl siding, the more susceptible you’re leaving it to insect, bird, or critter infestation.

Vinyl siding repair should be the first thing on your mind if you ever start to notice signs of any of the following pest infestations:

●        Termites

●        Bees, wasps, or yellow jackets

●        Carpenter ants

●        Powderpost beetles

●        Woodpeckers

Any indication that any of these pests are starting to accumulate within the exterior or interior of your home should warrant an immediate inspection for vinyl siding repair work.

Melting, Bubbles, or Blisters

Extensive heat and repetitive water exposure are primary suspects for causing signs of melting, bubbling, or blistering vinyl siding. Whenever moisture gets trapped under your vinyl siding and begins to evaporate due to sweltering heat, it causes your vinyl siding to expand, typically causing evident indications of exterior damage.

Leaving such blemishes unattended will only accentuate the deterioration and ultimately reduce your home’s structural integrity.


Any type of rot indicates that your siding needs to be replaced. Rot is a symptom that your siding is decaying badly. Rot in your siding is not something you should neglect. If you promptly replace your siding when you notice rot, you can prevent structural damage to your home from spreading and causing more extensive damage.

Visible Water Stains

If you see streaking or discoloration on your siding, this can mean that water is getting inside and harming the interior of your home. If you are faced with this situation, it’s a sign that your siding needs to be replaced.

Higher Than Normal Energy Bills

Siding helps your home retain heat, protecting it from the elements all year. Your energy cost will be affected if your siding doesn’t insulate well anymore.

Although, your energy expenditures may spike above average for various reasons. Once you’ve ruled out attic leaks, drafty windows, and poor insulation, you should evaluate whether damaged siding might be the possible cause. We recommend that you have a qualified siding replacement contractor examine things for you.

Frequent Maintenance

If you have to clean, repaint, or fix your siding every few years, that is an obvious indicator of a siding that has to be replaced. Ideally, siding should maintain its shape and color for at least eight years and sometimes longer. Siding is past its prime and has to be replaced if it is frequently chipping, peeling, or splitting, leading to regular fixes.
