From the time Chris replied to my enquiry till the end of the second skylight he installed he was completely professional. His workmanship was superb...very clean and tidy in my house...and at all times professional. Best of all was the incredible amount of light that poured into my kitchen after he installed my skylight. It was so good that I booked a second installation for the bathroom. this was a resounding success also. I would highly recommend affordable skylights
