Loft Conversion- 15 Jul 2016
Florin recently completed a two bedroom and bathroom loft conversion. A previous 'builder' had started this job but turned out to have been a 'cowboy builder'. Florin took the job on, and in his own words to 'rehabilitate it'. However, some unforseen issues came to light which resulted in the loft having to be restarted. I am now left with a structurally sound loft conversion with very good external finish. Florin maximised the space. He and his team has very good technical skills, knowledge base and the potential to produce high quality work.

We recently had our bathroom refurbished by Cubitt Wren in London, and we couldn't be happier with the result. From start to finish, they were reliable, professional, and always turned up when they said they would. The work was completed quickly without compromising on quality, and the whole team was polite and respectful throughout. Communication was excellent the entire way through. They kept us updated at every stage, answered any questions we had, and made the whole process stress-free. The finished bathroom looks fantastic, and it's clear they take real pride in their work. I would definitely use Cubitt Wren again in the future and wouldn't hesitate to recommend them to anyone looking for a reliable and skilled company.

After a previous contractor took our money and left our loft extension unfinished, we were devastated and worried about how we would ever get our home back to normal. Then Lewis from Lebelle stepped in and completely turned things around. Lewis was patient, understanding, and incredibly professional. He worked quickly, kept costs under control, and finished the loft extension to a standard we’re so happy with. The stress he took off our shoulders was unbelievable. We honestly can’t thank Lewis enough. If you’re looking for someone trustworthy, skilled, and genuinely caring, Lebelle is the company to call.

We have contracted H&J Properties for our house refurbishment in London. I was impressed with the team's professionalism and project management from start to finish. We had no plans or planning approved, so we wanted a design and build company who will be able to look after the project from start to finish. They did just that. Working with the architects and the planning application before starting the project planning. As always, there are, of course, unforeseen issues arising with the old houses in london but I could't be happier with the communication received from the team. Thanks for the great job.

Extensions- 16 Nov 2019
I was very lucky to find Cornel for my building work. His team were extremely hard working, efficient and respectful and the work was done very quickly and to a high standard. Most estimates for the build time were between 8 and 10 weeks - my work was fully complete in 6 weeks. Building control passed all stages of the work without any issues. He is equally proficient at the plumbing, electrics, flooring, tiling and decorating as the heavy building work, even restoring my garden so that it looked better than it did before the build. I am in a conservation area with close neighbours on all sides and Cornel minimised the disruption as much as possible and made efforts to keep everyone happy. His attitude to overcome problems and make sure that in the end you are a happy client drives his approach to the work. I had 10 builders quote for the job and Cornels quote was very competitive and the final costs were exactly as we had agreed. I had spoken to a number of his previous clients before going ahead and they were all very impressed with his work and had good experiences. It can be a difficult decision to choose a builder if you have no previous experience and given the potential for things to go wrong - but we made the right choice. I wouldn't hesitate in recommending Cornel and his team.

Restoration & Refurbishment- 3 Apr 2016
Vidas and his team did a fantastic job with our property refurb project and I can't recommend him highly enough. He completely stripped out property back to brick and rebuilt if from the ground up. We had some quite particular requirements requiring the removal and creation of new partition walls and Vidas was able to accommodate and direct us in how we could address each requirement. We are very happy with the finish and have had many compliments from other tradesmen on the quality of the work. We did have some minor snagging after the project was complete but Vidas was very accommodating in coming back to rectify these issues. I would highly recommend Vidas and look forward to using him again in any future projects.

Edmond did stellar work on the full kitchen renovation of our central London flat, and I can't recommend him highly enough. His professionalism, expertise, and attention to detail are on another level, and he is an excellent communicator. The end result was meticulous; he worked efficiently within the agreed timelines while resolving unexpected challenges and providing solid guidance throughout the project. Edmond also has a strong network of professionals who were just as reliable and easy to work with as he is. We also appreciated how tidy our home was left every day and how well all areas were protected during the build.

Questions to ask local loft conversion companies in Deptford

Choosing the right loft conversion company for your job requires finding someone who understands your home and your goals.

Find out which company can share your vision by asking the following questions:

What experience do you have with loft conversions in Deptford?

A local loft conversion company in Deptford will know the types of properties and building styles common in your area, as well as the planning and building regulations that apply. Ask about similar projects they’ve completed locally.

Are you insured, and do you offer a warranty for your work?

Insurance protects your home during the loft conversion process, while a warranty shows the company’s confidence in the quality and durability of their work.

How do you handle planning permission and building regulations?

Established loft conversion companies in Deptford should understand local planning rules and building regulations. Ask how they’ll manage permissions, inspections, and compliance to avoid delays or legal issues.

What is included in your quote?

Ensure the quote covers all essential aspects of the loft conversion: structural work, windows or skylights, staircases, insulation, labour, and any additional fees. Understanding this upfront prevents unexpected costs later.

Do you manage the project from start to finish?

Some Deptford loft conversion companies offer full project management, coordinating architects, builders, and tradespeople. Others may only handle part of the conversion. Clarifying this early on helps you understand what support to expect.

FAQ: Common questions about loft conversions in Deptford

How long does a loft conversion take?

Typically, a loft conversion can take between 6 and 12 weeks, depending on complexity, planning permissions, and any structural work required. Be sure to discuss the timeline with any potential loft conversion companies in Deptford before agreeing to start the work.

Do I need planning permission for a loft conversion in Deptford?

Many loft conversions fall under permitted development, but some require planning permission, especially if you’re adding a dormer, extending the roof, or living in a listed building. A professional Deptford loft conversion company can advise and handle permissions for you.

Will a loft conversion affect my home insurance?

Yes, you’ll need to update your home insurance to cover the conversion. Inform your provider about structural changes, additional rooms, and any changes to utilities or heating systems.

Can I stay in my home during the loft conversion?

Many loft conversions allow you to remain in your home, though noise and dust are inevitable. Some Deptford loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
