How much thought do you actually give your siding? Sure, you probably wash it often (you should), you probably notice if it’s become very noticeably degraded, but does it occur to you how the slightest defects in it, as is the case with most components of your home, can have far-reaching problems for your peace of mind.

Siding is one of those things that can look just fine but have all kinds of problems going on. Since people are reluctant to just randomly ask for an inspection unprovoked, we felt it was high time that we revealed some obvious symptoms of siding needing to be replaced – problems that you may be a bit surprised by.

At JDT Construction, we’ve been working with siding for years, and we’ve seen the long-run innovations in the materials, and the many ways things can go wrong over enough time. In that time, we’ve noticed these particular symptoms being the most common harbingers of siding in need of replacement, so if you spot any of these, you shouldn’t wait – you should call us right away. We’ll install the best siding you can get on the market, and we’ll make sure it can last for years to come and put an end to these symptomatic problems.

Energy Problems

A troubling sign of problems taking hold often reveals itself in the form of energy bill concerns. Are your heating or cooling bills getting higher? It may seem like increasing expenses would be the culprit, and that can contribute to it, but there are other potential causes for this.

This could be a problem with your roof, your windows, or your doors as well. However, often times, this is your siding. Like the rest of your exterior, your siding is a line of defense against the elements, and as your insulation is compromised and the seal is broken, you can lose heat or air conditioning through these weaknesses.

Recurring Need for Repainting

Does it seem like you need to paint your siding way more often than makes sense? This is something that, with modern quality paint, shouldn’t need to be done but maybe every five years or even ten years. If your paint is peeling, bubbling or fading more often, this means the siding itself is degrading.
Bonds between the paint and the siding are not effective anymore, the siding is warping and outgassing as it breaks down, and when this all begins to happen, a paint job just won’t hold up over the long term anymore.

Siding is Loose or Cracked

Now we’re getting into the more visible signs of siding being due for replacement. If your siding is getting loose or showing cracks, it means the entire façade is getting old, and in need of replacement.
Homeowners make the mistake of thinking this just means replacing a couple of panels, and moving on. If the crack or looseness is due to something hitting the siding, that may be true, but if it just seems to be doing this of its own volition, then the rest of your siding (which would be the same age) is not far behind it.

Rotting and Warping Siding

Similarly, if some of your siding is showing signs of decomposition or warping, simply replacing those offending panels isn’t going to cut it. This would be a costly way to maintain your siding in fact, as not long after, more and more of them will begin to show distortion and decay, and the whole thing can become quite a nuisance – a costly nuisance.

Mold or Mildew

Is mold or mildew beginning to grow on your siding? It may be easy to think a careful and somewhat gentle pressure wash, and perhaps some fungicide would solve this problem. In fact, it will probably seem to for a time. However, if these organic growths are that capable of taking root on your siding, it means that the integrity has been compromised, and the siding has become porous.
If things are growing on your siding, it’s time for new siding, period.

Siding is Fading

UV radiation from the sun has a tendency to fade things. It shows a lot in shingles, but also in siding. If your siding has begun to show signs of this fading, it means it’s endured too much UV at this point, and it will grow more brittle, it will begin to warp, and possibly dry rot as well.

Of course, it looks awful too, which hurts your resale value and curb appeal.

Dry Rot

Dry rot is the natural breakdown of materials like rubber, plastic, fiberglass and the like. Over time, UV radiation, outgassing, and just natural entropy will cause these substances to come apart and crumble.
Some kinds of siding (fiberglass and vinyl especially) are prone to this over enough time. If any of your siding shows this, you can be sure that, while not yet visible, this decay has begun in the rest of it too, and it’s time to remediate your exterior. This also often attracts pests which like to build nests out of dry rot debris, or are drawn to it as a sign of ways to get into places.


Are holes beginning to appear in your siding? This can be caused by weather, but these holes can also form from dry rot or simple breakdown over enough time. Even if one or two holes are all you see, expect more to appear on the rest of the siding.

Bubbles and Buckles

If your siding’s beginning to buckle, bulge or bubble up, that means that the sun has once more taken its toll, more in the form of thermal expansion compromising their integrity. It looks bad, it compromises the insulation, and it will cause the rest of the siding to suffer similar warping due to the pressure they will apply via the overlap.

Interior Paint or Wallpaper Peeling

It may seem like your interior paint or wallpaper wouldn’t be affected by your siding breaking down. However, damaged siding lets moisture and hot or cold air in, which can lay waste to your interior rather quickly.
