From start to finish the comms, install and more importantly the chaps doing the work were all excellent. Cant recommend them enough. House was looking a bit "tired" and now back to near new. I opted for the Doff treatment which even hired equipment cant touch for the temperature twinned with low flow (i did a fair bit of research myself). Didn't want to crudely "home pressure wash" the house/roofs as i know this can damage bits easily. The chaps with the Doff machine worked a treat!!! They also do soft washing if that's your thing. Thanks all!!
