Jerzy carried out several jobs for us. He has completely refitted our bathroom, he's rebuild a wall, laid front of house path, restored old front door, installed solid wall internal insulation, rebuild window frames, plastered a room and few other bits and pieces. He is extremely reliable and trustworthy. He's always been on time, works really hard and has always been honest about things and up front with any issues. Always consulted us for possible solutions. His work is to the highest standard and if I want a job done well, I always go to Jerzy.

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

Restoration & Refurbishment- 16 Feb 2018
Adam and his team did a brilliant job! My flat was in very bad condition. They gutted the whole flat and refurbished everything to a very high standard. Work performed included, new boiler and radiators installation, complete refit of bathroom and kitchen including all tiling, plumbing and electrics, new spotlights and wooden flooring throughout, new doors and skirting boards and all painting and decorating. They also arranged for all skips and rubbish clearance. I simply left the keys with Adam and he performed all work with minimum guidance. I would touch base a couple of times every week or when things needed to be discussed. He was happy to purchase most materials and provide receipts. I would highly recommend Adam and will definitely use him again for future work.

Extensions- 11 Oct 2023
We recently completed an extension at the rear of our property, along with a kitchen renovation and refurbishment of our reception hall. Abdallah and Hesham were instrumental in this project, providing us with a comprehensive work plan. Their labor costs were exceptionally reasonable, and they demonstrated unwavering dedication to the job. Their hard work was evident throughout the project, not only in the construction but also in coordinating plumbing, electrical work, and kitchen fitting through their skilled team. Abdallah co-ordinated well with building regulations, ensuring that our project complied with all the necessary standards. What truly stood out was their flexibility and willingness to adapt to changes and adjustments, especially when dealing with variations in material sizes. This adaptability greatly facilitated the project's progress and success. Thank you Abdallah and Hesham.

Restoration & Refurbishment- 3 Jun 2021
Enrico pulled in a great team to refurbish my bathroom. It wasn't a straighforward suite swap out as I added a window, switched from an electric to plumbed shower, properly plumbed in the sink and changed the orientation of the shower and bath. Enrico took all of the stress out of ordering and receiving all the different elements, he added in some great suggestions of final touches and kept close to all aspects of the project until I was fully satisfied with clear timings and payment plan etc. on top. It's an old house and there were curve balls from time to time but Enrico and the team took them in their stride and made it a great experience. I'm totally thrilled with the end result.
