Cavity Wall Insulation Costs


The cost of having your home insulated with cavity wall insulation depends on a number of factors.

How much does cavity wall insulation cost?

Cavity Wall Insulation Costs Depend on:

1. The type of home to be insulated and when it was constructed.

There are a few different periods when cavity wall insulation was used in home construction, pre-1978, 1978-1982, 1983-1993, 1994-2004, 2005 - onwards, so the period of construction will determine how much bonded bead is needed. Also if it is a detached home or bungalow.


2. The size of the cavity to be filled.

We will need to determine the size of the cavity to be filled. We do this by drilling a hole in the wall or looking at the gap behind your electrical box to determine the area needed to be filled.


3. How long it takes to do the job.

This is very obvious but the more time we spend on site the more labor cost we have to pay which increases the price for you. We are thankfully very efficient and spend as little time as needed on site reducing the overall costs for you.


4. How long it take for us to get to travel to your home.


The length of time it takes us to get to and return back to base will add to the price of insulating your home. We are based on the Mayo Sligo border in Barrackstown, Corballa, so the closer to us you are the less time we spend traveling.
