Everyone I dealt with from MASPER Build LTD was very responsive, professional, efficient. I can certainly say that my experience with them is extremely positive. From Veronica at the desk who was always prompt with her replies and very helpful; to Marian and Denis who came on site to rectify the huge problems caused by previous contractors who had made a real mess in our place. Marian and Denis were both great at their job, very polite, careful and respectful. I very rarely write reviews, but they really deserve to be praised.
Excellent installation of air-conditioning unit. Information was provided in advance concerning appropriate brand and installation process, and billing was clear in advance. On the day, they arrived on time, they protected all floors and surfaces, and the final finish is excellent.
Really great work. Easy communication and punctual.
Masper Build Ltd were excellent: A call / inquiry was quickly answered (Veronica), an appointment quickly done, and the engineer that came Mr. Marian Ciulei was on time, very thorough, explained clearly what is the job needed and proceed with it directly after agreement. Adding to that, he did everything with professionalism and left the area cleaned. We highly recommend the services of Masper Build Ltd. It is the second year we are dealing with them and we will continue for years to come.

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.
