We wanted three new Velux windows fitted, two 'balcony' type and one larger replacement. We live over 140 miles from Graham, yet he was happy to come and fit the windows based on drawings we supplied. Work was carried out on time and for a fair price. The house was left tidy at the end of every day. Work was carried out to a high standard, the two lads were polite and quiet, just getting on with the job, very rare these days! I can see why Graham is a certified Velux installer. You may have to wait a while to get an installation date because Graham is so busy, that tells you all you need to know.
