Highly recommend Molyneaux builders. We had an extension built by Gavin and his team who were brilliant - efficient, professional, high quality workmanship. Communication was excelllent. They worked extremely hard and the end result just exceeded our expectations and has given us a really great space. - Amy S

Gavin and his team did a fantastic job and we are so happy with the finished result. The price quoted was reasonable and it was all finished on time. They were punctual. Reliable and very tidy. Nothing was too much trouble and they were a pleasure to have in the house. Jo was excellent from the first contact and all queries were answered promptly. Would not hesitate to recommend them and will definitely use them again. - Gill Behennah

Would highly recommend Gavin and his team. We were recommended this team and waited 18 months for work to commence. We can now understand why! Throughout the build at every stage we were kept informed. Alternatives were offered and many excepted. Time away from site was minimal normally waiting building material special to site. All the team where polite when I butted my nose in and a pleasure to have around. We are now fully enjoying their hard work and we have no hesitate in recommending the company to all. Thanks Gav and the team.! - Pete & Anne

From all of us here we are over the moon with the work, the in-laws are absolutely delighted, and the kids cant stay out the playroom and I wont use any other builder for my next projects. You and Luke have made the whole process as easy as a build like this could be, many thanks. - Matt and Claire
