Basement Conversion Professionals in Mexborough, South Yorkshire

“James and Pat and the team built our two storey extension in 2015. They did a great job, on budget (always extra costs for unexpected work or changes to our ideas)! We were really pleased to have JP McDonagh do the work having approached half a dozen builders locally for quotes. The team were reliable and considerate (our 2nd child was born halfway through the build in true Grand Design's style!). They were on site every day they said they would be. It was good to have a single point of contact in James and the breakdown of quote and invoices meant we knew exactly where we were with the costs. There were minimal issues and the minor problems with sub contractors were all resolved through James or Pat which meant a hassle free build for us. They are clearly experienced and knowledgeable and were able to suggest different ways of doing things which made the outcome even better. Would use again and have recommended to others.”

“Excellent and professional great lad's did a fantastic job for me and my husband will definitely recommend you thanks for everything”
