Quick Quotation Form

Matt and his team converted our garage into a dining room and built a detached double garage in 2013. The standard of work was excellent and has received many favourable comments from our friends and neighbours. We have no hesitation in recommending Matt to carry out any type of building work.

Eric and Ginny Sanderson

MJH Builders did our 2 room side extension with vaulted ceiling, we were extremely happy with it. This in turn lead to Matt and his team doing all the hard landscaping in our garden, it was no small job, but due to Matt's attention to detail, knowledge and hard work it looks amazing. we would highly recommend MJH Builders.

Jill & Mike

Matt and his team have built an extension, deck and porch for us over the last few years. We have recommended MJH Builders to several friends. All work is carried out to an excellent standard, pricing is very fair and transparent and the work is done very quickly to minimise disruption. Matt's team are friendly, trustworthy and reliable. We wish that we had found MJH Builders before when we had other building work done!

David & Vicki

The work was well planned by Matt and he always talked me through what would happen and when. I was very comfortable working with Matt and his team. Always punctual, always polite/courteous and always very tidy with their work and with the working area. All work was completed on time. I would have no reservations in thoroughly recommending Matt for his building work – very professional


Matt and his team did a fantastic job of our extension. They were prompt, tidy and nothing was too much trouble. The quality of the work is outstanding and our neighbours even commented on how organised and efficient they were. They are lovely guys and they felt like part of the family. We would highly recommend Matt.
