Work has been completed professionally and to a very high standard.Excellent reputation, so highly recomended!
Impressive. Recently this building company completed a bathroom remodel for us, and everything from the tile work to the plumbing was done with precision and care. Easy to work with, always answered our questions, and ensured we were happy with each step of the process. They went above and beyond just to make sure the job was done right!
We recently had a new kitchen done by this building company, and we couldn't be happier with the results. The team was professional, efficient, and kept us updated throughout the process. The quality of the work is excellent, and they really paid attention to the details. Our new space looks fantastic, and it's exactly what we envisioned. Highly recommend them to anyone looking to improve their home!
We were very impressed by Ionut’s professionalism, friendliness, and excellent communication skills. He was very responsive from the very start and advised us well on the work at hand during his visit to our property. Due to changing personal circumstances, we aren’t quite ready to proceed with our project at this time, but when we do, we will no doubt entrust it to Ionut and his team.
I can't recommend these guys enough, they work really hard and make sure everything is right. Really easy to get along with too and provide many different building services. I'll use them again. Thanks!
Very good and honestHe is excellent in planningTrustworthProvide excellent service
Very humble people. Provided me quotes without hassle. Highly recommended
I recently had my kitchen fitted by this company. Carpentry, tiling, electrics, plumbing, painting and flooring were undertaken to a very high standard. It far exceeded my expectations and I am delighted with my new kitchen. I highly recommend this company and will use this business for any future works I may need.
They turned our living space into a true work of art. Their meticulous attention to detail and unwavering dedication to quality shone through every step of the project. We wholeheartedly recommend them for any construction or renovation needs in the UK. If you're looking for skilled builders, professional construction services, or top-notch home improvements, this team is the best choice.
After building an extension for my daughter I have just had my garden completely landscaped. Everything I asked for nothing was a problem. Work was completed in time they said would take and the price was very fare.i have recommended this company already to neighbours and friends.
We engaged Sigma for a large single storey L-shaped extension. We chose Sigma as we found Ionut to be honest, hardworking and trustworthy and the quotation was very competitive. We are extremely happy with our extension and cannot recommend Ionut and his company Sigma Building enough.In particular, Ionut is extremely dedicated and works tirelessly to deliver a high-quality finish within or even earlier than his estimated timescales. Nothing is too much trouble for him, he is willing to go out of his way to deliver on what we as the customer wanted. He is highly communicative and he and his team are extremely helpful, polite and friendly. He is without a doubt extremely skilled and is willing to turn his hand to anything. As part of our work, Sigma built a large L-shaped extension, a garden gym, new patio, new driveway, new fences, LVT flooring, swapped our upstairs layout and installed a new bathroom. We are extremely happy with all of the work that Ionut and Sigma have delivered and have recommended Sigma to several of our friends.If you are looking for a hard-working, trustworthy and diligent building company, then Sigma is undoubtedly the best choice for you. Thank you Ionut and Sigma
We contacted Sigma building for some patio/garden work after seeing the fantastic job they had just done of our close friend’s extension! They matched the same quality and attention to detail they did on theirs, on our work and we can’t recommend enough. We gave them a bit of a brief and some pinterest inspiration pictures and they delivered over and above. To also mention a few important aspects you’d expect which they delivered on: friendly and personable, aswell as managing the project, (materials and skip delivery), and also speed and hard work. Will definitely be contacting again the next time we need some work done!
Sigma Building recently knocked an interior brick wall down for us, built a new stud wall and stripped out the bathroom. Ionut is a really nice guy and did a great job. Very responsive to messages and completed everything as said he would for a fair price. Would highly recommend.
I have used Sigma for a number of projects, and cannot recommend highly enough. Always punctual, work carried out to the highest standard, very tidy, nothing too much trouble and a complete perfectionist. From a complete kitchen install (including plumbing, electrical, tiling and lighting), ti patio construction and creating under stair storage solutions, Sigma did it all and I wouldn’t go anywhere else for home renovation work. Ionut is a lovely person and I recommend him and the business highly.
