Carpentry- 15 Aug 2025
Could not recommend or rate Karl higher if I tried, after recently becoming a homeowner I had Karl come and give me prices for some jobs I wanted doing, initially the skirting boards, after talking to him and realising just how versatile he was he ended up doing most of the house. He’s completed a media wall, moved a stud wall, completed panelling in a dining area, fitted wardrobes and acoustic panels, laid flags in the fireplace and in an emergency he managed to fix a massive cracked pipe with a leak behind a wall and saved me a fortune. His prices are so fair, especially for the quality of the work, he treats the job as if he was working on his own home, nothing is rushed and his focus is on doing the job properly. Really nice fella and easy to talk to about the work that’s going on, already have him booked in to do more jobs, my house would be nowhere near where it’s at now without him

Extension Builder in Runcorn
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 Runcorn?
