Highlights
"Louis and his team did an outstanding job on our renovation. They are skilled, efficient, and always kept us in the loop. Every detail was finished to perfection, and the whole process felt smooth and stress-free. They stuck to the timeline, delivered amazing results, and were a pleasure to work with. We’ll definitely be calling them again for future projects — highly recommend!"
"we wanted to change our shower which involved new tray/shower/surround, new lights and fans in ceiling, micro cement walls, new shower rail, extended internal wall, decoration and removal of existing bath. Louis knew exactly what we wanted, was great to deal with, value for money, and completed the job in a very professional way where he explained what was happening and any decisions we had to make. Would definitely use again if we needed any further work done in the house"
"I had a burst pipe under my floors due to old pipe work and was left with no hot water or heating I had been given a couple of recommendations for people to do the work both turned up and looked they clearly decided they didn’t want the job . Sadly they kept me hanging on for over 2 weeks .Having used Louis several years ago for a garage conversion I contacted him He came round the following day and looked it wasn’t an easy job. But he appreciated the urgency of the and within the week 2 of his team arrived and the job was done . Definitely my first contact for future work . Thankyou"

Before you hire a builder
Never pay a large deposit up front — agree a staged payment schedule tied to completed milestones, and hold a small retention until snagging is done.
Get it in writing: an itemised quote with scope, materials, start and finish dates, and how any changes (variations) will be priced.
Be wary of a cash-only price or pressure to start tomorrow — both are red flags for an unaccountable job.
Ask to see a portfolio of completed work like yours, plus recent references you can contact.
Check the credentials and registrations that matter for this work — and that they are current.
