Sorry for calling Graham out for nothing, but when the pest controller's infra-red camera showed a variation at the top of our insulated walls (which you did in 2002!!), we assumed it was missing insulation. Turned out to be the timber lintel that was the variation, and the insulation was still right up to the top, exactly as your man, Simon, had pumped in the wall insulation in September, 2002!! Please thank Graham for his excellent service and calling to let us know he was held up for 10 minutes in the traffic. We will contiune to tell everyone how well your insulation and company has perfomed over the years!!
