10 Signs Your Siding Needs To Be Replaced ASAP

Do you know when is the right time to replace the siding of your house? This is a huge home improvement project that you should not take lightly. First of all, it will cost you a lot – especially if you need to replace the whole thing. Not only that, if it does need replacement, this is something that you cannot put off for long. If the outside is compromised, it will not be too long before the inside will also be damaged.

This is the reason why you need to regularly inspect your house to check if you have to replace the siding. It is not that complicated to do. You just have to get to know the various indications that prove your sidings are showing signs of damage.

Here are 10 of the most popular signs that you need to look out for.

Dry rot

This is tricky to detect because there are sidings that look really good on the outside but is already rotten on the inside. You want to be able to detect the rot before it becomes visible to the naked eye. So how do you find out if there is dry rot somewhere in the exterior of your house? You get a tool with a rubber handle and use it to tap on the siding. Use the handle part and listen to the sound that is being emitted. You will know if it is rotten when it sounds different – like soft or dull. If it is not rotten, the sound should come back sharp. In case it sounds rotten, you need to have it replaced.

Warped and rotted

Sometimes, if you failed to detect it early, the siding will look rotten or warped on the outside. This is a visible sign that you need to have it replaced. You can also use a screwdriver to poke a part of the siding to see if the rotting has gone through. If it is still solid underneath, there is no need to have it replaced – at least not yet. But you might want to have it inspected anyway.

Cracked or loose siding

If you see a couple of boards that are loose or cracking – you might want to have these replaced immediately. You do not want it to fall off and possibly destroy other parts of the house. But if you notice that a big portion is coming loose, it might be best to have your sidings checked. There might be a bigger issue lurking underneath that has to be solved. You want to deal with this so you do not have to worry about any leaks coming into the house – specifically where the boards are loose.


Small holes are fine but you need to keep an eye on it. That hole can get bigger and that will pose a bigger problem. You want to make sure that it will not reach that point. You should also figure out the cause of the hole. If it is insects, you need to do something about it. But if it was caused by a debris hitting it hard, that should be an isolated case.


If your siding is showing bubbles underneath, that means it is trapping water. That is not a good sign. Sidings are used to keep the moisture away from the interior walls of your house. If the bubbles are there, that means it is not doing its job. You want to make sure this is corrected.


Some people like it when their original siding fades over time. There is nothing you can do to completely stop this. Sometimes, it looks really well – especially when you maintain it properly. However, you also have to realize that the fading means the material has lost its waterproofing abilities. You either replace the siding or make sure the existing one is waterproofed.

Regular repainting

Have you been repainting the sidings more frequently than before? Usually, if you have to repaint the siding every 5 years or less, that is a sign that it might need replacement already. If the material is still of good quality, you do not have to repaint until after 8 to 10 years. But if the peeling and cracking happen within 5 years, then it means the quality of the material is compromised.

Molds and mildew

A fungus is never a good thing. If you find any sign of molds, mildew, or fungus anywhere in the exterior of the house, you need to look further into it. This means water is passing through and is trapped somewhere inside the walls. This has to be investigated further. You need to call a professional to help you out.

Peeling paint inside or loose wallpapers

Apart from looking outdoors, you should also inspect the inside of your house. If you notice a specific place where the paint is always peeling or the wallpaper is coming loose, that might be an indication that the siding outside is damaged. Of course, it could be something else, but you might want to consider it being connected to the sidings of the house. The problems inside the house could mean that moisture seeped under the siding and is already affecting the interior walls.

Higher electric bills

This is specifically for your cooling or heating bills. A good siding means proper insulation for the house. If you notice a higher heating or cooling bill, that means the insulation in your house might be compromised. It could be caused by something else like a dirty filter or damaged HVAC system but if these checked out, then it might be your sidings that is causing the higher bills.


These are the common signs that the siding of your house needs to be replaced. Now that you know, it is time to take a walk around your property. You need to inspect the exterior of your house to see if any of these signs are true. If yes, then you need to make plans to have it replaced. If you act quickly, you might be able to salvage the other parts and only need to replace a smaller portion.
