Day 5 of the black out after a storm and thanks to our insulation we are warm in the house. We don't even have a stove or fire only candles lit and we are warm. This is the best upgrade investment we've made to our house.

Kudos to these guys. They came out, lifted the roof tiles to 3 roofs with no access and for the first time I saw how bad the insulation was in there (some had no insulation....) They topped up my attic insulation, re-floored and pumped the cavity wall in both my house and garage. Highly recommended this team, great team spirit on site.

We were looking to get our cavity walls insulated and heard about West Coast Insulation from a friend who had their house done in Galway. They had got their attic insulated with Rockwool and walls with ecobead bonded bead insulation and were very pleased. So we gave West Coast Insulation a call and they did a great job and the house is a lot warmer now; saved a fortune on oil, this winter. We would recommend West Coast Insulation to anyone looking to get their attic insulation or cavity wall insulation in the Galway Mayo area. John was very helpful and sorted out the grant paperwork also.
