Problems caused by cavity wall and Loft insulation

There are millions of properties in the country which have had cavity walls or loft insulation installed and of course insulation is one of the greatest and cheapest way to keep homes warm and cut your energy bills, but there are instances where insulation is not the right solution and can actually lead to bigger problems. It may take a few years before you notice anything but damp could still be damaging your home before it becomes obvious. It’s likely your energy costs will be rising too, as your heating will have to work harder to maintain a comfortable temperature.

Why Should We Remove Cavity wall insulation?

You will have to remove your cavity wall insulation (if installed by incompetent, non-accredited installers or unscrupulous companies) because this could cause penetrating damp, mould and condensation if:

☛ It’s old and worn out
☛ Homes with stone guttering
☛ Urea formaldehyde used for wall insulation
☛ Timber & metal frame properties
☛ Homes in high exposure area (Find out if yours is)
☛ Damaged walls such as cracks in the brickwork, render or pointing
☛ DPC (damp course proof) minimum 6 inches above the ground
☛ Muck/Loose Mortar not removed before the insulation was installed
☛ Structure of the home is not suitable for walls insulation
☛ Blockages have entered in the walls due to building work

As:

  • Gaps in the insulation allow heat to escape and damp to penetrate
  • If the insulation gets wet it will act as a sponge, drawing water across and holding it against your walls
  • The insulation can prevent adequate ventilation and cause damage to, for example, a steel frame, suspended wooden floors and wall ties





These warning cannot be ignored, if you suspect your home might be affected or if you can see if there are cold spots on walls in your home or unexplained patches of damp then we would advise to call a professional as soon as possible. It may take a few years before you notice anything but damp could still be damaging your walls before it becomes obvious. It’s likely your energy costs will be rising too, as your heating will have to work harder to maintain a comfortable temperature.





Why Should We Remove loft insulation?

Loft insulation is the cheapest way to save money and energy on your bills. However, incorrect loft insulation can cause problems such as penetrating damp, mould, condensation, ventilation If:

  • It’s old and worn out
  • It’s been damaged or has become wet
  • Condensation due to lack of ventilation in your loft space
  • Badly fitting or loose insulation material will allow heat to escape
  • Water damage due to roof leaks or burst tanks/pipes
  • Up to 25% of a household’s heat loss can be through a poorly insulated roof!
  • It was installed incorrectly and, for example, doesn’t reach the internal leaf of the wall plate

As:

  • If the insulation gets wet it will act as a sponge, holding water against your ceilings
  • An old and worn out insulation will not have the same effect as the new insulation
  • Heat will escape if installed incorrectly or by incompetent, non-accredited installers
  • A lack of air flow will cause condensation which will eventually lead to mould and damp
  • Gaps in the insulation cause cold spots that allow heat to escape and damp to penetrate






These warning cannot be ignored, if you suspect your home might be affected or if you can see if there are cold spots on walls , ceiling in your home or unexplained patches of damp then we would advise to call a professional as soon as possible. It may take a few years before you notice anything but damp could still be damaging your walls before it becomes obvious. It’s likely your energy costs will be rising too, as your heating will have to work harder to maintain a comfortable temperature.


Reduce your energy bills

The gradual increase in energy prices over the years created a huge financial burden on many low income households. However, homes are not installed properly will take longer to heat and indirect result of higher energy bills means resident will be paying more to heat. There are many reasons homes shouldn’t have been insulated, but they have due to bad installer those have not assessed properly. Insulation has also been installed on not suitable properties meaning heating will have to work harder to maintain home temperature. Now the best way to save money on your energy bills is to remove old insulation so the house can maintain better living environment.

Areas of the UK exposed to wind and rain

The principal change was that the use of full-fill cavity wall insulation was not permitted in areas of very severe exposure to wind-driven rain where fairfaced masonry is used for the outer leaf. However, the rules also reflected the reduced risk where impermeable and rendered outer leaf constructions were used and therefore permitted the use of full fill insulation.

Exposure Zones   Approximate wind driven rain
(Litres/m2 per spell)
Sheltered 1 Less than 33
Moderate 2 33 to Less than 56.5
Severe 3 56.6 to Less than 100
Very Severe 4 100 or more

How can I be sure that all the insulation has been removed?

Once we’ve removed the insulation from your walls we inspect them using a 360o video boroscope. This allows us to see 2m into the cavity in every direction. When the works are complete our technical manager will sign a report to confirm that all materials and obstructions have been removed.

Can flooding affect my cavity wall insulation?

Yes. Flooding can saturate the insulation. When this happens the insulation must be removed and the cavities allowed to dry out before any replacement insulation is installed.

Moving into a property with cavity wall insulation

If the property has cavity wall insulation and is cold the insulation is likely to have been wrongly or poorly installed. We can advice about the property to see if there are problems with the insulation and recommend how it can be put right. We have found that even new build properties can have very poor standards of insulation.

What are the signs of failed cavity wall insulation?

Penetrating damp and mould are the main signs that you should contact a professional to assess your existing cavity walls insulation. You may also notice that your home is experiencing more heat loss, although this will be gradual and remains overlooked by many property owners.

Is cavity walls insulation suitable for all type of homes?

No, cavity walls insulation is not suitable for certain type of homes such as damaged walls, timber frame cavity, metal frame cavity, cracks in the brickwork, damp course proof below the line and many other factors.

Why do I have to remove my loft insulation?

Incorrect loft insulation fitting can cause problems such as penetrating damp, mould, condensation, ventilation which is not good for property.

Do we need to remove degraded loft insulation?

Yes, loft Insulation removal required if your loft has lack of airflow, wet insulation due to water leaking tanks/pipes, degraded as laid some years ago, heat escape due to incorrect fitting.

Do we need to remove insulation after work carried out?

Yes, if plumbing work carried out in the loft space may have resulted a damage or, if your loft has been subjected to woodworm treatment and the old insulation was not removed first as often new insulation is simply laid on top of the old existing material and residents don’t know what is underneath.

What warranties should I expect?
