Conversions - General- 23 Nov 2017
Calvin and Jimmy have been absolutely brilliant, and have been the best builders that I have employed. So much so, that I have subsequently asked them to do a whole shopping list of things, from fitting a kitchen to removing an old fireplace. They are always on time, very polite, kind and knowledgeable. Best of all, they get things done quickly without any fuss. Calvin has been invaluable in sourcing items from trade required for the latest project, and clearly talks through requirements of any project. I would very happily recommend them for the excellent value they offer and fantastic level of workmanship.

Carpentry- 27 Mar 2026
The job was executed to the highest standards. Tzouliano was clearly very knowledgable and experienced. He explained what work needed to be done, what he would do and was very honest about what was possible and how durable it would be. He was also very polite and respectful (he took his shoes off every time he walked around the flat without needing to be asked). I would definitely recommend him for any carpentry job.

Loft Conversion- 22 May 2015
Hiring a good builder with all your expectation can be a very difficult experience. Especially to those who never done large scale building work. Having herd of people nightmare is one that you always dread that you may be the next victim. With George and Stephen there is probably few of a kind out there. I did three major work with George and I cannot highly thank enough of the quality of their work. George is very knowledgeable in the trade and has huge experience in getting the perfect loft. The added extra quality he has done on the gable end is something special. He is a multi-skilled tradesman and did all the work on his own with electric, plumbing, tiling, rendering etc. He also did good job in my bathroom too but that wasn’t an easy job having a bay window. The other work he did was the rendering whole of my external building. Again I did not expect this sort of rendering but the end results was exceptional. George kept his schedule and timing and finished within the predicted timescale. He was always on time and finished the daily with good clean and tidy of the whole area of his work. There was minimum disturbance throughout the house in the entire 8 week of his work. Lastly the professionalism within his work was always kept to the agreed standard, he always updated me with written work every week which I founded very helpful. I can recommend George to anyone and definitely too friends and family. Thanks again to G Lofts for everything.

Restoration & Refurbishment- 19 Apr 2026
Didn’t return to finish the job, respond to calls or messages in response to finishing the job. Sadly wouldn’t hire Ovi & Mihai (O&C) again. Friendly & responsive initially. Worked well, on time, eager to please, did a good job - not perfect but adequate, average attention to detail but corrected when asked. We initially had a faux chimney put in, they touted for more work & provided alcove shelving/cabinet ideas which we subsequently hired them for. They worked intermittently (dad around for first half of job then left for Romania) as this was agreed as best for both parties. However they left the job incomplete once paid (were paid on time, each time, with no bargaining). Didn’t respond to texts or calls, leaving cabinet doors unfinished, large chips & cracks unfilled. Laminate was also poorly cut around hearth stone, left chimney cutout unfinished with no cement to the base. Lack of respect and wouldn’t hire again as cannot trust they won’t disappear. Note previous reviews.

Hard Flooring- 23 Feb 2020
Andrei provides great communication and very professional service. He was very flexible and worked extremely hard to get all the work done in the shortest time possible, but he did not compromise on quality. He worked very efficiently and considering all the work he had to do, he still left the house clean and tidy. The attention to detail was second to none. I’m extremely happy with my new flooring and would definitely recommend.

Questions to ask local loft conversion companies in Blackheath

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 Blackheath?

A local loft conversion company in Blackheath 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 Blackheath 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 Blackheath 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 Blackheath

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 Blackheath before agreeing to start the work.

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

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