I have have just had my loft done by Selcom, a local firm with an office on Brockley Rise. They were brilliant. I left them with my keys and went to work every day, even on holiday and had no problems. Found them easy to deal with and they came up with solutions to a few issues in the house. All in all, a good company and no where near as stressful as I thought. Also not as messy - but they hoovered every night!
