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

Bricklaying- 13 Oct 2018
Build wall at the side of the house on which a new wrought iron gate was to be hung and replace cracked and worn bricks along the top edge of the front garden retaining wall, with brand new blue engineering bricks. Daniel arrived to complete the posted job at the exact time we had previously agreed. He coordinated and worked in tandem with another (independent) tradesman I had appointed to remove the wrought iron railings from the front of the house, have them galvanized and powder coated and then replace them, when the new bricks had been installed. Daniel showed an ability to get with other tradesmen whom he had never met previously and still do an excellent job. I am really pleased with the end result and have no hesitation in recommending Daniel for other jobs, where brick laying is required. My front garden looks so much better now that all the work is finished and I cant thank Daniel enough for a job well done.

What experience do you have with similar extensions in St Helens?

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 St Helens extension builder’s ability to deliver a result that meets your expectations.
