Things don’t last forever. On top of that, insulation is the same. Even though it lasts a long time, it won’t last forever. Depending on the type of insulation, it loses its heat resistance (R-value) over time as it settles. This makes your insulation less effective, which could lead to higher energy costs. When the insulation in your home goes out, bad things happen. Some of these problems are annoying, like a house that drafts. Others can cost you a lot of money in the form of high energy bills… or they might even be bad for your health because of mould, mice, and allergens. How do you know when to replace old insulation?
Insulation should be changed or added every 15 to 20 years. But depending on the type of insulation installed, its rating, how much it has compressed and moved over time, and whether any damage has been done, it may need to be replaced or retrofitted sooner.
Switching out insulation is complex and might be hard in many older houses in the UK. You just don’t know what kinds of problems or chances to insulate you might find.
Read this blog to learn when to replace old insulation? And start over. Let’s look into the details.
Is It Worth Replacing Old Insulation?
To be worth replacing old insulation, it might only be dry, dust-free, and squished. Removing it isn’t needed in this case. Letting old insulation stay in place can be extremely helpful. If you leave the old insulation in place, it will continue to help you insulate while serving as an extra layer. Therefore, if the old insulation is up to the depth of the joists, try to lay new insulation across the board.
Because of this, they will fill in any holes in the old insulation. Wet old insulation, on the other hand, should be replaced. Placing new insulation over old, damp insulation will spread the moisture around. Unfortunately, this will only cause mould growth, resulting in higher gas bills. Insulation replacement is always a good idea, significantly since heating costs increase. It’s also worth considering more because the money spent on new insulation will pay for itself in future years.
Common Signs When to Replace Old Insulation?
Several things can harm insulation or make it less effective over time. Knowing these things can help you figure out when to take it off and put it back on.
Moisture
One of the most common things that damage insulation is water. Leaks in the roof, walls, or base can let water into your house. This water can soak into your insulation and make it less effective. This can also cause mould to grow, which is dangerous for your health and worsens the insulation.
Pests
Rodents, bugs, and birds are some of the pests that can damage your home’s insulation. They might build nests or holes in the insulation, weakening it and making it less effective at stabilising the temperature. Their urine and droppings can also make the insulation smell bad and get dirty.
Age
Insulation has a lifespan, just like any other material. If it settles or gets squeezed, it might get thinner and less able to insulate. This is especially true for free-fil insulation, like fibreglass or cellulose.
When Is Insulation Removal and Replacement Necessary?
Sometimes, insulation must be removed and put back into place to keep a home warm and energy-efficient.
Damage
If your insulation is worn down from water, bugs, or old age, it won’t keep your home at a comfortable temperature and could even harm your health. In these situations, removing the broken attic insulation and installing new insulation to keep your home safe and comfortable is very important.
Renovation
You might have to remove it and put it back in insulation if you want to change your home. This is very important if you change the layout by adding new walls or making current ones bigger. Getting rid of old insulation and putting new insulation in the right place can help your newly rebuilt area be as energy-efficient as possible.
Upgrading Insulation
Because insulation technology has improved, newer insulation materials use less energy and cost less. If your current insulation is old or doesn’t meet current standards, you should eliminate it and add something more energy-efficient.
Why Hire Professionals for Insulation Removal and Replacement?
While some homeowners may attempt to remove and replace insulation, hiring professionals for this task is highly recommended. Here are a few reasons why:
Safety
Insulation can be hazardous if it’s not used correctly. When you move some things, like asbestos insulation, they can release dangerous fibres. Professional engineers ensure proper safety measures are taken to protect the workers and the people in the house.
Efficiency
Insulation removal and replacement are labour-intensive processes that require specialised equipment and techniques. Professionals have the knowledge and experience to efficiently complete the job while minimising disruptions to your daily routine.
Quality Installation
If insulation is not placed correctly, it can leave holes, spaces, or compression, which makes it much less effective. Professional placement ensures the insulation is spread evenly and put in the right place to maximise effectiveness.
Peace of Mind
If you hire professionals to replace your old insulation, you can rest easy knowing the job will be done safely. This allows you to work on other projects or jobs while trained professionals handle this important task.
Quality Assurance
Companies that professionally replace old insulation often offer contracts or promises. This gives you more confidence that any problems will be dealt with quickly and correctly if they do happen.
You can ensure your home is comfy and energy-efficient by knowing how important it is to maintain your insulation and getting professionals to replace it.
What Does It Cost to Replace the Insulation?
The cost of insulating a home depends on many things, such as the type and material used. Glass wool or PIR is most prevalent in UK lofts.
Before you start insulating your loft to the recommended 270 mm thickness, you should know that the whole job will not cost more than £1200. Fibreglass shielding is part of this choice.
A PIR stiff board is the standard way to insulate your loft. Once more, get ready to spend about £2500, twice as much as fibreglass. Conversely, PIR is often used because it has better heat performance with less material (100mm+50mm).
Government Support Schemes For Free Home Insulation
The UK government has also set up free home insulation schemes to help low-income homes that can’t afford it. You can improve your house and lower energy bills by getting free insulation through the Great British Insulation Scheme.
- You can be eligible if your house has an energy performance certificate (EPC) of D to G (check your EPC).
- Eligibility criteria falls between Council Tax bands A and D in England or bands A and E in Scotland or Wales. Check your Council Tax band as well.
You can own your home and rent from a housing group or a private rental. If you already rent, talk to your owner before applying. You’ll need to get their clearance before you can put up any insulation.
Home Insulation Types Covered By Scheme
You might be able to get free insulation to install the following:
- Cavity wall insulation
- Solid wall insulation (internal or external)
- Loft insulation
- Flat or pitched roof insulation
- Underfloor insulation
- Solid floor insulation
- Park home insulation
- Room-in-roof insulation

Summary
In summary, insulation replacement is an essential aspect of home maintenance that should not be overlooked. Hiring experts to do the work ensures it is safe and done quickly and saves you money on your energy bills over time. Choosing the right insulation according to your needs and budget is also essential. The government’s Great British Insulation Scheme is here to give you free insulation if you are a low-income household.

People Also Ask
Fibreglass insulation typically needs to be replaced 15-20 years into its life, as it can quickly become dirty, wet, moldy, and ineffective if there’s a roof leak or water damage.
Unless damaged, insulation can last 80 to 100 years in most houses before needing to be replaced. However, insulation can start falling from fibreglass batts after 15 to 20 years. So if your insulation was installed well over a decade ago, it might be time for an inspection or a home energy audit.
Most of the time, you can put new insulation on top of old insulation as long as the old insulation isn’t wet, mouldy, or made of. If the old insulation is dry now but looks damp, you should figure out what went wrong and fix it.
