Highlights
"Brilliant job. I can happily recommend this company .Reliable. Tidy .In time for the work, Very happy"
"GL Mason refurbished my home. They replastered in 3 rooms. Redecorated through out and also fitted a new bathroom and kitchen. I was very happy with the finished product."
"Mark and his team were excellent with painting I needed for my house. A previous builder left my home in terrible shape and Mark and his team were able to get the job done, they even went above and beyond and did some extra work for me in the bathroom. They arrived on time and finished on time, incredibly polite and left my home very clean when they finished. I will be using them again for another job for my mother."

This trade isn't licensed in the UK, so anyone can set up. TrustMark is the only Government-endorsed quality scheme for work in and around the home - check whether they're registered, or find a TrustMark-registered business.
Check the TrustMark registerNever 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.
