Exceptional Craftsmanship Proven by Our Clients Since 2008

Really pleased with the work completed. I hired High Grade Carpentry to fit some contemporary baton fencing across my garden wall, create some benches with storage and lay garden decking all using an exotic hardwood. The team were extremely knowledgeable and recommended the best way to go about everything. They ordered in materials for me and finished the job on time within the figure they quoted for the work. I would highly recommend them.

Customer from Southsea

Had High Grade Carpentry carry out significant building work last year to improve a loft conversion and install new stairs. Matt and team were brilliant – very professional, approachable and helpful. Minimum disruption to us and neighbours, always leaving the place clean and tidy at end of the working day. Would highly recommend.

Claire Pollard

Matt and the team did a great job on our loft rework/extension. He sets high standards of himself and the team and was communicative and timely in completing the job, with the quote being both accurate and comprehensive. The final result is exactly what we were hoping for.

Everyone who came to work on the house was friendly and happy to work around us living there still, and they made sure to keep mess to a minimum as a result.

Hope to one day get you back to complete the second part of our planned work!

I have just used Matt of Highgrade Carpentry to correct a previous builders dreadful work.

Matt and his team were very professional and skilled craftsmen, very knowledgeable and helpful at all times. They completed the work well within the timeframe and with a minimum amount of fuss and disruption. They did an excellent job in transforming the appearance of our home to something which we can now be truly proud of. Thank you Matt, Richard and Dean. I would not hesitate in recommending them to anyone.

Roy Steele

Matt has been an absolute pleasure to work with over the past few weeks and never fails to impress. He has undertaken a few jobs for us recently, responds quickly and professionally and costs are always reasonable. Work is always completed to a very high standard. I could not fault High Grade Carpentry and would recommend to all!
