Selcom completed a loft extension for us in 2019. They did a great job, everyone was really nice and friendly. They did a great job and worked with us to make sure we got what we wanted and quickly resolved any issues etc. About a year later and no issues to report all still looks great.

Super unreliable company - total time wasters! They came over to give me a quote, took some measurements and then never got back to me despite chasing them several time. Always said I'll have it soon. The following year I tried again, they always said they'll call me back to book an appointment but never did. In the end I got them to make one and the day before the appointment they cancelled and said they are too busy to come over.
