Joinery & Cabinet Making- 30 Jan 2015
Robert is dependable, helpful and generally good to have in the house and on the job. Just one caution, my job was replacing kitchen worktops and he's not a plumber so we had some snags with the sink. Even so. I am a getting a quote from him for another woodworking job.

Extensions- 21 Jan 2023
I’m a bit late adding this review but Vasile just reminded me. We are really happy with the home that Vasile built for us. It’s a Victorian terrace over 3 floors that needed a full renovation including electrical re-wiring, new plumbing etc plus a gf side and rear extension plus a loft conversion. Vasile and his team worked really hard to get us the finish we wanted. He always was on-hand to solve problems from building control to water pressure. He was always very friendly to work with and extremely respectful. We always got the impression that he wants to make his customers happy and takes pride in his work. Because of Covid and issues with materials and the labour market, our job took longer than expected but I think this was really outside of anyone’s control. We now have a really beautiful house that we love living in and it’s in no small part thanks to Vasile. I have recommended Vasile to friends already and have shown some of his potential customers round our house. They were always really impressed and inspired.

Restoration & Refurbishment- 24 Apr 2019
I hired Dursun Altun and his team for a full refurb of 3 bed house. His business co-ordinator Ayse was helpful throughout the whole process and listened to the design requirements we had. Dursun provided full new plumbing and new boiler and all new electrical work. We had all our windows and doors replaced and are happy with the work done. His team fitted new bathroom, shower, toilet and also the kitchen. They also did some carpentry and provided shelves and doors for closets. His team decorated/painted and cleared up at the end of the job making sure it was all left clean and tidy. They did a good job and delivered on time! Dursun and Ayse made sure we were happy with the job and were lovely to work with. The job was done to a good standard and I would recommend them.

Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

Loft Conversion- 4 Apr 2018
We cannot praise Johnny and his team enough. They were simply fantastic throughout our project - they have done a beautiful loft conversion, and transformed the rest of the house.. installed two new bathrooms, opened up the downstairs and installed a new kitchen, installed new front and rear doors and bifolds, restored original fireplace, decorated. They are delightful guys to have around, Johny keeps a firm grip of the project and makes sure things don’t get delayed. They are proper craftsmen and real perfectionists. They work hard, they have an eye for detail, they are unfazed by problems, they kept to schedule - you couldn’t ask for more. Johny was around to give advice at any stage we needed, they left things clean and tidy and have a real pride in their work. We would highly recommend Johny to anyone - he’s a great, trustworthy, hardworking and genuine guy who does exactly what he says he will. This was our first major building project but we couldn’t have been in better hands.

Questions to ask local loft conversion companies in Barbican

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 Barbican?

A local loft conversion company in Barbican 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 Barbican 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 Barbican 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 Barbican

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 Barbican before agreeing to start the work.

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

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 Barbican 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 Barbican loft conversion companies offer strategies to minimise disruption, but in complex projects, temporary relocation may be advisable.
