Could not fault the team from start to finish. The garage has been transformed from an old, cold, concrete jungle to a fully functional garden room. They took care of the roof, wiring, internals and new sliding doors and it has all been done to a very high standard. Me and the wife are very happy and would definitely recommend Dynamic.

I received quotes from numerous companies for a complete house renovation including a double story side/rear extension and single story kitchen extension to completely transform a property from an old 3 bed semi to a modern 4 bed. Paul from PMCS Joinery came out as scheduled and was quick to provide a comprehensive quote that was broken down and detailed so I was clear what was included/not included and it was transparent. The quote was competitive and as Paul had come highly recommend and I’d seen some of his work I went with them. A start date was agreed and work commenced on time. Paul managed the project ensuring all work was at a high standard, Paul was always on site. All trades he brought in were professional and quality. Paul and his teams joinery was exceptional, all his staff polite and courteous. Any extras or challenges Paul managed and talked me through any ideas, options and costs. The quote was honoured despite materials rising. I’ve recommended PMCS to many friends, neighbours and family. The house has been complete to a high standard and I’ve been pleased from start to finish and highly recommend them. Many of my neighbours also commented on the standard of the property and how professional they were. Thank you to PMCS joinery

2 story extension front and back. Luke built the shell up for our 2 story extension, was very professional and knowledge, there was a few unforeseeable issues with the build that he came across which he was able to fix very easily, workmanship was extremely neat and pretty much everybody who has seen the work has commented on how neat it has been, our plasterer who came in afterwards has he's taken a lot of care not just inside but also on the finish inside as a lot of builders only care about outside and leave other to sort the inside out but luckily not luke, he also helped out massively when let down by other trades to help catch up and get ready for 1st fix trades, we also added in a lot of extras which weren't originally discussed but the work got carried out as usual to a very high standard at a very reasonable cost. They work very fast only really being held up by weather. I would definitely recommend Lh builders for any building work you need.

I work as a sole trader with a passion for what I do, no matter what. I have been in the building industry since leaving school in 1990, attended college to do a bricklaying course while working for my father who was also a bricklayer/ builder, who could turn his hands to other trades, and I am the same, with one thing in mind, to do a good job at a fair price. I am hardworking, reliable and trustworthy above all.

What experience do you have with similar extensions in Southport?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Southport extension builder’s ability to deliver a result that meets your expectations.
