Wonderful work by Conrad to make a small box room into a decent size bedroom by demolishing our existing brick wall between two bedrooms and replacing with a stud work one. Removal of all the rubble, plumbing, electrics and plastering were included in the work and it was all done cleanly and swiftly. I would recommend Conrad highly, he's a lovely chap and very reliable

Hector and his team did a full renovation of my 1960s flat, including boiler, central heating, electricity, bathroom, kitchen, plastering of walls, floors, and painting. From the start Hector impressed me with his attention to detail. He suggested good improvements to the original plans, and had solutions to problems that had stumped the other builders I had been talking to. I trusted Hector to delivery premium quality rather for my home and his team lived up to that expectation. The plastering was especially good. Hector is well organised and advised to have every little detail written down so we can ensure we were on the right page. Along with clear timelines for when materials needed to be ordered for this kept everything running smoothly, and the build completed on time. Hector's man Wilson managed the team day to day. He was always polite, friendly, and helpful when I dropped by to see how the work was going. There were a few small snags after the build (perfectly normal and to be expected for this kind of work) and Wilson and his men sorted them out quickly without any hassle. No complaints from me, I would recommend Hector and his team for your home renovation.

Ermir, Vlad and the Nami team are not only skilled craftsmen, they’re trustworthy and incredible to work with. They turn up on time, they stick to their promises, they proactively communicate to make sure you’re up to date, and they are joyful lovely guys to be around. There were problems with my project due to my building being old & some things being unforeseeable but with every hurdle they came up with practical solutions to make it work. The situation could have been incredibly stressful and upsetting, but Nami worked with me every step of the way with great kindness & a can-do attitude. The final result is gorgeous - even my downstairs neighbours love the work Nami did for me. I cannot recommend them more highly, hire them, you won’t be disappointed.

Ged is the perfect builder for someone who does not know what to do, who to trust, or what you might need to do to achieve your ambition. We have used many different trades people, ranging from cowboys to good workers that rip you off. Ged was better than anyone we have used before.

He help with loads of advise, worked hard and to a good time table. I cannot express how happy we were to have Ged on our job. He and his team had amazing attention to detail. Polite and helpful. I look forward to having Ged Work on future projects soon. You are in good hands. High praise, but Ged deserves it.

Radilina and the team were very clear on progress and issues during a difficult full house renovation, with all potential amendments to scope always fully explained, detailed, and costed. The materials and suppliers recommended and liaised with were always high quality, and Radilina was able to successfully source discounts and alternatives where appropriate. The team were also honest and proactive with damage and snagging (inevitable in a build of this scale), which has been very helpful and much appreciated.

The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!

Zen came round to see job and returned competitive quote quickly. He was able to start a few days later, turned up on time and completed the works with the designated 2 day time frame, working essentially 2 full days (not my experience of builders in UK who are only onsite for 5 hours a day). He cleaned up the site and did a good job. Would use him again.

Conversions - General- 20 Oct 2014
I can highly recommend Wayne and his team for their recent work. Our job was the conversion of our home from two flats into one house and the job included: - removal of artex and re-plastering - removal of partition walls and re-building of new room corner and door rehang - building spindles and links etc on wooden staircase - fitting electrics: switches and pendants - fitting trims and replacing moldings to match those damaged by previous conversion to two flats In terms of price, I found their quote to be competitive - not the highest and not the cheapest but we chose them as we were impressed by Wayne's attention to detail when he came to look at and price the job. This approach continued throughout and ensured that we were very clear on costs and detail of each element of the job. Also impressive was the job timeline - the team started the day we agreed and finished a day early! (This is a first for any builders we've hired!) And in turn, when it came to the follow-up snags (of which there were just a couple and one was down to faulty product, not an error in build) Wayne was very quick to respond, getting back to us within 24 hours on a weekend too! I will definitely invite them to quote again.

External Works and Repairs on Large House for Freeholder We had hired Chiro to complete External Works and Repairs on the Exterior of a building that comprised 2 flats on behalf of the Freeholder. From the outset Octavian and his crew were very professional to deal with in terms of negotiating the price, start date and the works to be completed. The project involved repairing brickwork, roof tiles, ridge tiles, parapet walls, pointing, facia, plaster work, fixing windows/sills and finally sanding and painting etc and required a comprehensive repair of the exterior of the building. Much of the work was quite intricate and required careful repair of damaged areas and often coming up with creative solutions to get a good finish. The workmanship and attention to detail was very impressive and even involved them doing online research to find an alternative to old ridge tiles that were no longer available. Any issues or additional requests that arose were favourably received and dealt with immediately. The project started and was completed on the agreed dates and the site was left clean and looking well. Overall I would highly recommend Octavian and his crew to other clients.
