Our loft insulation needs were explained in detail along with a breakdown of costs. The job involved climbing through five hatches into each of the different areas of the attic to discard old obsolete insulation and lay fresh 300mm insulation. They managed to get the whole attic done as specified with raised platforms to the water tanks etc in a day ! They worked constantly with only one lunch break. Afterwards they tidied up - you would not know they had been ! It is nice to know friendly after care is always there. Excellent service - would recommend.
