Does cavity wall insulation work?

Yes. It basically works the same as a jumper or your overcoat does to keep your body heat in. Insulating the walls will reduce the rate at which a house loses heat making your home a lot more comfortable and cheaper to run.
 

Does it give off any smells or fumes?

No. The product is installed dry. No liquid or chemicals are involved in the installation therefore  no smells or fumes are given off.
 

I can’t see it, how do I know the right amount of material has gone into my property?

The installing machines are set to ensure that the material is installed to the correct density. Before any work is carried out, our surveyor will also visit the property to take measurements. As part of the quality control procedure the size of the property is cross checked with the materials used from stock to ensure that the property has been fully insulated.
 

How long does it take to install?

Around 2 to 2.5 hours for a semi detached or a bungalow and about half a day for a standard detached property.
 

Does cavity wall insulation cause damp?

No. If the property has no damp problems before the installation of cavity wall insulation, it will certainly not have any afterwards. Our site survey visit will check to ensure that the property is suitable. In addition the product has been independently tested by The British Board of Agreement (BBA) and has been successfully awarded a BBA certificate.
 

Does cavity wall insulation prevent damp?

Dampness in buildings can be caused by a variety of things. If the property is suffering from condensation, which normally shows as black mould on cold wall external walls, then yes insulating the walls will help. This problem is caused by warm moist air hitting a cold surface and condensing which makes it the ideal condition for mould spores to start growing in which will then be seen as a black stain on the wall. The mould can be cleaned off and decorated and will generally stay away during the summer months but usually reappears once the temperature drops, around October and November time.

The insulation will make the wall surface temperature warmer and a lot less likely for moisture to condense. However, it is not a guaranteed cure by itself, as the property also needs to have adequate heating and sufficient ventilation to allow moisture to escape.

A survey of the property will identify the cause of any damp and whether insulation will help.
 

I have noisy neighbours will insulating the wall between the properties help?

NoThe wall between the properties is called the party wall. Sometimes this is cavity sometimes its solid. The way sound travels is a complicated issue. Sound can be transmitted through the fabric of the building therefore insulating this wall will give little, if any, sound improvement
 

Do you offer any guarantees?

Yes.  A 25 year  CIGA guarantee is offered on all full installations. See more.
 

How many holes do you need to drill?

This depends on the dimensions of the property. Small holes are drilled between the mortar joints to a specified pattern. The holes are only 22mm, about the size of a ten pence coin View picture.
 

How do you stop the insulation going into my neighbours’ property?

A cavity barrier is inserted into the cavity which ensures that only the property being insulated is filled.  View picture.
 

I only want one wall doing can I have only this done?

If this is the only wall that can be done on the property, then yes. If other areas also needs doing, then no. We can only issue CIGA guarantees on complete installations.
 

I have a painted rendered house, can you guarantee an exact match with my paintwork?

No guarantees can be made in obtaining an exact match. We do however carry the most common range of Sandtex external paints. Every endeavour is made to obtain as close a match as possible.
 

I have vents around my property what will happen to these?

Our fully trained installers will ensure that all essential vents are kept free which may mean removing the vent and sleeving it and replacing it with a new one. If the vent is a non essential vent then this can be safely sealed up.

Some examples of essential vents are those supplying air for a fuel burning appliance, larder vents, and vents for suspended timber floors.
 

How long will the insulation last?

For the lifetime of the property.

Every property is different and a survey will assess the suitability of your home for cavity wall insulation. There is no charge for a survey.
