Client Reviews


Very friendly and knowledgeable, quick turn around from survey to instalment. we had a front bay window fitted, the job was done professionally with quality workmanship clearly displayed.


I didn't realise they did building work so when we wanted a large bay window/small extension we thought we'd give them a call. It's just been completed and it is superb work.


J R Gilks have done a lot of amazing work on my property would highly recommend! Great Price and Service from the Team. More work planned in the future!


J R Gilks built our conservatory. Very professional and extremely tidy. Would recommend 100%.
