Once you’ve had your external wall insulation installed, it should last for quite a while without needing replacing, unless of course you fall victim to the elements or damage. There are lots of signs that your external wall insulation will need replacing and you’ll need to search for external wall insulation near me, so here are a few of them…
How long should my EWI last?
First things first, it’s important to know exactly how long you should expect your insulation to last. Each manufacturer offers a different guarantee on their work, both for the installation and the actual product. The guarantee for the labour comes from the installer and the guarantee for the system will come from the manufacturer. Your EWI system should last for decades, with most installers giving a 25 year guarantee.
If your EWI was installed using ECO funding, a 25-year insurance backed guarantee should also be provided. The guarantee is insured by your installer, but will also be underwritten by an independent insurer, meaning you are protected if your installer or system manufacturer ceases to trade later down the line. The terms of your guarantee will still be met by your insurer.
The temperature in your house isn’t right
This is a vague statement, but an important one to keep in mind. If the temperature in your home is inconsistent (changing often), always too hot or too cold, or certain rooms are draughty, it could be a sign that your insulation needs replacing. Moreover, if you’re seeing a change (rise) in your energy bill, this could also be a sign that your insulation needs to be replaced, as your energy bill should remain consistent.
Someone is suffering from an allergy
This reason sounds ridiculous, but ageing, damaged or improper insulation can be a breeding ground for mould, allergens and bacteria. These allergy symptoms could include itchy, watery or irritated eyes, throat or nose. Sometimes, homeowners will report difficulty breathing, but this is usually when they have a pre-existing asthmatic condition or breathing disorder. Someone in your home could also suffer from itchy skin or a rash.
You’re struggling with leaks or infestation
If you’re regularly finding damp or condensation in your home, it could mean there is an issue with your insulation. When moisture fills the air pockets between the fibres, it means the transfer of heat gets slower and your house will get colder. Once the insulation is wet, it’s truly about as much use as having no insulation at all, and will need replacing. However, you are not likely to come across this issue unless you live in an area that is prone to extreme weather.
If you find evidence that some little critters have been in your home (e.g. mice, rats), you might be in need of an insulation replacement. The creatures could have nibbled their way through your insulation and into your home, or property damage could have left your building with enough access for them to get in. After all, a mouse can get through a 6-7mm hole and a rat can squeeze into a 20mm one. If you notice any small holes, it’s time to get your insulation replaced immediately!
