Conversions - General- 29 Dec 2021
We struggled to get anyone interested in our refurbishment project originally, Mark answered an ad for a small part of the job and ended up being able to take on the whole thing thankfully. Our project was to completely strip out a 1960's maisonette flat, install internal insulation which involved extensive battening of all the external walls, new plasterboarding & plastering finishes to walls and ceilings, tiling and a completely new bathroom and kitchen install. To complicate things further, as enthusiastic DIY-ers we wanted to do lots of works ourselves as well and few builders would have worked alongside novices as well as Mark did. He was always happy to give advice or take over works when we realised they were beyond our skills or time ;-) Our project was constantly evolving and challenging - as we discovered hidden rotting floor joists and the joys of 60's engineering - door lintels - who needs those?! Mark was always there to help us problem solve and get the job done professionally and to high standards and this was all done throughout the challenging last year of lockdowns etc. Without hesitation we'd recommend Mark and his team. He was always reliable, flexible as the project developed and had excellent attention to detail and we couldn't have completed our project without him. Thank you Mark!

Painting & Decorating- 17 Jan 2019
We engaged Maciej for a plastering and painting job to repair damage following a roof leak. He also sorted out replacing some of our roof insulation that had also been damaged. Maciej was very efficient and creative in what he proposed. Even though there were unforeseen issues with the job he kept to his original quote. He was tidy and managed to complete the job without putting us to any great inconvenience. Maciej is trustworthy and reliable. I would have no hesitation recommending him.

Conversions - General- 15 Apr 2026
Luke and Diti are both amazing guys for this project. Honestly speaking they aren't the cheapest quote, but they are definitely beyond expectations. Luke was the only builder who gave a full transparent quote on each item and what was needed for the conversion. Really quick work and good planning because I have 2 cats and they did everything with enough people onsite to minimise the time. Speaking of work, it is good, we kept in communication and they were always happy to explain and adjust slightly according to my concern/question. Leave this comment after the work has been done for few months and everything is solid.

A great experience. Work was completed quickly and to a good standard with an unexpected extra (sorting out the electrics for a light in the crawl space). Most tidy builders I have ever employed. Quick responses and good communication. I'd happily use Prime Contractors again
