D.L.CONS LTD
Rating: 5 out of 5
Extension Builder in Winchmore Hill
Hi, I’m Dan, the owner of D.L.CONS LTD – a small, skilled, and reliable building company based in E9, London. With 25+ years of experience, I’ve pretty much done it all – and done it well. I specialize in bathroom and kitchen fitting, bricklaying, painting & decorating, and carpentry, and over the years, I’ve worked on everything from domestic extensions to shop renovations. Whether it's transforming a small bathroom or building an entire extension, my team and I focus on quality, precision, and attention to detail—because great craftsmanship speaks for itself. We mainly work in E9 and the surrounding high-end postcodes—Hackney, Victoria Park, London Fields,and Islington. If you're looking for top-quality workmanship with no shortcuts, I’d love to hear about your project. Let’s build something great together.

Carpentry- 8 Apr 2026
I’m really happy with the work carried out. He came in to fix my steps after a previous builder had damaged them and left them unstable, and the difference is night and day. Everything now feels solid, secure and properly finished. He also fixed the skirting boards and installed my desk, all to a very high standard. What I really appreciated was how professional he was throughout and the advice he gave along the way, which showed real experience and care for the job. Overall, a really high-quality finish and a great attitude. I wouldn’t hesitate to recommend him.

Plastering- 26 Jun 2016
We hired Manu and his team to plaster our summerhouse, relocate two radiators and fit a new bulkhead ceiling in the lounge and install LED tape. He was knowledgable, professional and considerate and I highly recommend Manu and his team. Not only did he understand the project for the bulkhead, but he came up with another suggestion which we went with, and friends and family agree looks amazing. The finish on the plasterwork is perfect and Manu and his team worked hard and even left the summerhouse cleaner than when they started! It is great to work with a team who pay such attention to detail, listen to the client and get the job done to a high standard. It was a risk to go with Manu as he didn't have any feedback when I hired him. I actually got him to quote so I could compare prices with someone else I had in mind to do the job, but when I met Manu I felt he would be the better person to do the job as he listened and understood exactly what I wanted and so I ended up hiring him instead. I wouldn't hesitate to hire him for any future jobs. Thank you Manu and team!

Loft Conversion- 18 Sep 2024
He acted fraudulent and without due care and professionalism. Shortly after commencing the project, he came up with variations, denying several things were not included in quote when we asked for a complete quote for refurbishment. He then started cutting corners and did terrible unethical things which of course building controls refused to sign off and ran off with money paid to him then started threatening me which of course I had to report and document with the police. I had to correct what he did at great cost to me and waited this long just to complete the project first before taking up this matter. I kept all the records carefully and plan to sue. I recommend to stay away from Prep, his company, structural engineer etc.

Hard Flooring- 8 May 2019
I was very pleased with Igor’s work on the flooring and under floor heating, so decided to ask Raimundas to quote for a large bathroom, hallway, fitted kitchen, rewiring of all electrics and flooring throughout the rest of the flat. Due to work and my partner living overseas, I needed to trust somebody for a long length of time with my keys and my property. I was able to have a lot of the work done while not in the country, communicating with pictures, videos etc. Obviously this was important for me and made having the work done easier. There were also many problems with the kitchen delivery and other things that didn’t go according to plan. Raimundas was patient and polite at all times, even though it was sometimes rather frustrating. I highly recommend his services, and would definitely consider RR Construction for the next job

Jason and his team built to exact specifications an outhouse with in ground swim spa and decking. I am actually in love with the build and how it has positively impacted our lives. Jason and his team were great communicators and everything was built exactly how I envisaged. Building Control and council signed off everything with great ease and we now have pretty much a holiday home in our back yard. We've got a purpose built studio flat with private access, a spa style shower room and a large gym/games room. The team came up with innovative ideas to store the tank and the electrical cabling and it is a beautiful space to have. Would highly recommend them and would welcome working with them again in the future.

Groundwork & Foundations- 24 Jul 2026
A great team you can trust. I’m a cautious customer, but they immediately put us at ease with their professionalism and obvious experience. We needed a concrete slab pumped into a long, narrow extension with access from one side only, and they managed the entire process smoothly from start to finish. The result was a perfectly level, high-quality slab. Thank you!

Garden Maintenance- 17 Sep 2017
I hired DS Developments to completely landscape my small front garden. This involved clearing and levelling the area; moving and re-securing a bike shed; laying a patio and lawn; and a number of finishing touches. The area went from somewhat of an embarrassing eye-sore to an area of pride. One that several neighbours have already made compliments about. David provided a professional service from start to finish. His quote was more than I expected, but his knowledge and vision gave me the confidence to select his services. He provided a selection of options and stuck to budget; adapted well to new ideas/suggestions; and informed in advance where the cost would be impacted. He and his team also were as tidy and considerate as possible and I highly recommend their services.
