What Our Customers Say

We called Walter Moran Insulation to see how to insulate our holiday home on Achill to ensure its longevity. We were very pleased with the solutions provided and the price asked for.

Works had been planned taking into account our limited availability as we live away and, finished accordingly, when the weather allowed it. The house enjoys a new youth and should be protected for the next 10 years, knowing it is in front of the sea and the Atlantic wind.

We already have been able to feel the difference inside, with less heating needed. We are very pleased with the final result and would recommend Walter Moran’s work without any doubt.
