Andrzej has done a number of jobs for us in our listed Georgian Farmhouse, we now would not use anyone else.

Andrew Jamieson

Andrzej has worked with us renovating a barn. It is difficult to explain how good he is. He covers all the aspects that you require to complete a fantastic job. Nothing phases him and his skill and knowledge is second to none. He is a pleasure to work with!

Phil & Caite Guest

Andrezj has renovated our farmhouse from top to bottom and done a great job. He also has given us some good ideas along the way.

We needed a wall and gateway to the rear garden of our property, and wanted to change an upstairs cupboard in to a toilet , got in touch with Andrzej who built our block wall and two facing brick pillars with gateway, and managed to fit a toilet and sink in the space that was a cupboard previously. very pleased with the results don’t know how we managed without it. We were so impressed with his work we enquired about what he could do regarding a shelter attachment to our garden house, Andrzej suggested a wooden gazebo and we are so pleased we went with his suggestion, we now have wonderful space for our hot tub and great area for socialising in the garden, thanks again Andrzej, a true craftsman.
Would definitely recommend.

Mr & Mrs Fleming

Contacted Andrzej regarding a problem we had with our chimney stack suffering from spalling on the brickwork and also the garden brick wall. Andrzej recommended we have it rendered and we had it done in grey render with base coat and mesh, and new coping stones fitted on the wall.
Excellent job, very pleased with the result.
A conscientious worker and would definitely use again, so many people have commented on our new wall !!.

I first met Andrezj in 2017 whilst he was doing some work for my brother-in-law on his new-build bungalow. From the work he was doing for my brother-in-law, I could see that Andrezj was competent in many building trades including joinery, plastering and plumbing.

My wife and I purchased our current property in 2016 which is a 4-bedroom country cottage. The property was in good condition but there were certain things needing modernisation and others that we just wanted to change. Using Andrejz for this work has been beneficial since he can turn his hand to Joinery and Plastering. He also has a lot of knowledge and experience in other building trades and so can provide some very useful advice.

Since 2017, Andrezj has done the following work for us;

Installation of an ensuite bathroom

Build and installation of fitted bedroom furniture

External rendering of garage

Installation of new kitchen

Forming walk-in wardrobes in son’s bedroom (1st & 2nd fix joinery and plastering)

Andrezj is a polite, friendly and hard working person. He goes about his work in a professional manner and always displays a high level of workmanship.

I would highly recommend Andrezj for any joinery, plastering or plumbing works. Last year I recommended Andrejz to two of my friends and he has since completed plastering works for them too.
