Conversions - General- 17 Apr 2026
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

Bricklaying- 24 Aug 2016
Nick has been an absolute pleasure to work with. He was always very polite, his work was neat and tidy and very considerate of others around him. He took the hassle out of building/renovation and even helped out with organising things once his job had finished. He originally came to quote on possible subsidance, which ended up not being subsidence at all and instead did some internal renovation for me by bricking up some doors and knocking through walls. I can definitely recommend Nick and will get him to do some work for me in the future.

I would like to say that this work was completed perfectly. They were always on time and cleaned up after themselves. The plumber was there all day and never stopped. We found them all very approachable and helpful. No pressure sales. Would gladly have them back for another job and would recommend them to others.

Bathroom Fitting- 30 Oct 2020
We can highly recommend Harpal, who completely refitted our old 1980s bathroom. I was anxious about starting this project, as I work from home and had heard horror stories from friends about length of time their bathroom refits took! Harpal said he could complete in a week and was true to his word. He showed up every day with his colleague and they worked long days, sticking to his quote and delivered on time. He stripped out the old bathroom fittings, tiles and flooring, skimmed the walls & built a box frame for the bath. He installed a new heated towel rail, replaced the bathroom fittings including vanity unit and wall cabinet and retiled to a high standard. Harpal is multi-skilled, quick working and reliable. We are so happy with our bright new bathroom and will certainly consider Harpal and team for any future work in the house.

Extensions- 20 Aug 2016
Fantastic service, Lucas and Darota are an amazing professional team always reliable and our kitchen extension is to an exceptional standard. Darota offers an amazing interior design service. The builders have been punctual, worked really hard and when we have come home from work the house is always tidy so we don't even feel the house is being renovated. We offered LD Property services more work after our kitchen extension/complete refurbishment to include a complete renovation of all our home including garden and driveway. The project has been managed brilliantly as we work full time this has been really helpful.

RS Building successfully delivered two full back-to-brick refurbishments and a new-build development for us in Greenwich, including demolition and construction of four new dwellings. Their level of workmanship is exceptional, and their attention to detail is second to none. As experienced property developers, we’ve worked with many contractors—but RS Building stand out for their reliability, quality, and professionalism. We have since recommended them to several colleagues, all of whom have been equally impressed. Our only regret is not finding them sooner. We look forward to working with them again on future projects.
