Conversions - General- 3 Sep 2025
Big refurb of 1650 sq ft flat, plus building 2 additional ensuites. Initial quote seemed reasonable but then once in, costs started to rise exponentially. Some work was done well, like the building component and flooring, but finishing was poor. Painting, particularly of internal doors, was done poorly, without removal of fittings first, so lots of overpainting and insufficient prep and coats. Regrouting and redecoration of front and rear patios was done poorly, with weeds already poking through. There was damage to existing bathtubs and WCs by not protecting surfaces and pouring waste materials down the pan. Everything was an argument with constant demands for more money e.g. front door only painted one side as the other side not included under "paint door". Lots of "snagging" - I only have manual on/off control of heating and hot water as "smart" thermostat won't connect, there are odd water pressures through some fixings...and now there's a leak under one of the WCs...

Conversions - General- 4 May 2025
I Hired Em to do my ground floor reno, which included a garage conversion and remodel of my kitchen where 2 internal walls were removed. Very glad I found Em to do the job. Him and his team was efficient, friendly, tidy and hard working. We encountered obstacles along the process (which is normal for any renovation) but Em gave his opinion, listened and we came to the best solutions. Very happy with the result. Em is a reliable, punctual, knowledgeable, fair, down to earth guy and one of the best if not the best contractor I have hired. Highly recommend. Some before and after pictures.

Extensions- 9 Feb 2019
I had the pleasure of working with Habib on the renovation of my house. My review of his work during renovation: 1- He has done excellent job in rewiring the house. he segmented each floor and kitchen and put them on separate ring, he expanded consumer box for future growth as well as installing wired smoke and security alarms 2,3 - He fitted pipe and installed unvented cylinder system with water softener perfectly including multiple heating control zones which I can control each floor individually (I love it). 4- he built a beautiful and prefect extension in garden, he considered all building regulations such as structural integrity, fire safety, energy efficiency, damp proofing, ventilation and other key aspects that ensure a building is safe. In addition to above he has very good personality and he is approachable to discuss changes or add new tasks to job (unlike some builders whom don’t like it). Throughout the course of the renovation, Habib was a consummate professional. He was accurate in his initial assessment of the scale and cost of my project. Good work takes time to complete. Patience is required when you work with a perfectionist. Although my project took time to complete, I have a wonderful outcome and a work of art now. I can recommend him highly and without reservation. Thank you, Habib, At the end I would like to thank Jake for his part and hard-working during renovation of my house. Hamid

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

Bathroom Fitting- 27 Mar 2024
Driton was able to give me some great advice, fix the problem on the spot and stop me paying out for a new cistern and toilet. So he saved me a lot of money and the inconvenience of having my bathroom turned upside down with building work, re-tiling etc. I'm very grateful.

I originally contacted Joe from Orama to fit a new kitchen for me. When he came to give me a quote, I hadn't yet chosen what I wanted. He really took the time to make several recommendations and so I decided to go ahead with him to design my kitchen fully and fit it. The team were so easy to work with and most importantly respectful in my home! Their attention to detail is second to none. He really understood the style I liked in one conversation. The finish is flawless. I highly recommend them!!

Quality Builders completed a remarkable domer and loft conversion for us on 2/10/2023, and we couldn't be more pleased with the results. From the outset, their professionalism and attention to detail were evident. The initial consultation was thorough, and they took the time to understand our vision for the space. Throughout the project, communication was excellent, with regular updates on progress and any necessary adjustments. The craftsmanship displayed by Quality Builders was exceptional. Every aspect of the conversion, from structural work to finishing touches, was executed with precision and care. Their team of builders and contractors demonstrated expertise and skill, resulting in a finished product that exceeded our expectations. Not only did Quality Builders deliver on time, but they also adhered to budgetary constraints without compromising quality. Their transparency and honesty throughout the process gave us peace of mind and confidence in their abilities. The transformation of our space is truly remarkable. The addition of the domer and loft has added both aesthetic appeal and practical functionality to our home. The new space is light-filled, spacious, and seamlessly integrated with the existing structure. Overall, we cannot recommend Quality Builders highly enough. Their commitment to excellence, attention to detail, and professionalism set them apart in the industry.

Khin and Senh did an amazing job redoing all the skirting in our home. Their quote was competitive and their workmanship outstanding. They helped us source the materials to our specification for a great price, handling all the delivery details and were happy to pick up any bits and bobs to get the job done. Each day they arrived on time and often worked late to accommodate the fact we had carpets coming in the following week. After each day tools and materials were squared away and they would send updates on progress. The final product was top quality and has nicely finished off our home as part of a large book of renovations. Finally any snags that I did notice they were happy to come back and address, I couldn’t have wished for any more from these guys. All the best !
