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.

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.

Restoration & Refurbishment- 20 Jul 2015
We hired Zebra Property for a complete strip out and refurbishment of a GF flat. The JOB: The job included initial removal of existing bathroom, kitchen and flooring. The works itself were for a side return wrap around kitchen extension, basement refit, installation of new kitchen and bathroom, new windows (including velux) and bifold doors, tiling and complete decoration throughout. FEEDBACK: Zebra were a great company to work with on this job. Communication levels were clear. There were inevitable delays to the project but there was always a focus to get back on track and deliver as quickly as possible. The resulting finish is a high standard throughout the property, with any minor snags completed quickly. Thank you!

I recently had a bathroom and utility room refurbishment and am very pleased with the results. Hanif was fantastic, coming up with solutions to transform our bathroom from a tired room to a modern and stylish space. There were no problems that he wasn't able to fix and was great at making sure we ended up with the refurbishment we wanted.

Questions to ask local loft conversion companies in New Eltham

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 New Eltham?

A local loft conversion company in New Eltham 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 New Eltham 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 New Eltham 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 New Eltham

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 New Eltham before agreeing to start the work.

Do I need planning permission for a loft conversion in New Eltham?

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