Excellent finish and the plasterer went beyond what was asked for by fitting the new light as well for me. There was some confusion over the materials to be used but luckily this was resolved. I would recommend First Fix Group

Loft Conversion- 3 Feb 2016
Ian did an excellent job with our loft conversion. He put us in touch with an architect who specialises in loft design and arranged all the council building inspection direct. He took full control of the building work and always arrived early and worked hard. He and his colleague carried out all the work themselves to a very high standard, making excellent use of the whole loft area. Our loft conversion required 5 large steels and these were all installed professionally without any problems. The dormer, new stairs and all woodwork was done excellently too. The plasterwork finish was also good, making decorating very easy for me. The ensuite is also great, very well tiled with a large shower and inset shelves. I am happy to recommend Ian for loft conversions.

Loft Conversion- 5 Dec 2018
Firstly the date of job posting and date of completing is all down to me not being ready with finances!! Secondly, and more importantly, GG Property were the most wonderful and professional bunch of lads you can hope to met. The work was done with such enthusiasm and to such a high level of detail. We could not be happier with the finished job. Thirdly, the great building work aside, GG Property were polite, happy, friendly, punctual and great communicators. All emails answered swiftly and with accurate information. No question was to silly and no concern (this was our first major building working) was to small to be addressed. Finally we are so pleased with work we are awaiting a quote for our bathroom and look forward to getting that job completed!! In short my experience with GG Property was nothing but top quality work and customer service. Any fears of the classic 'cowboy builder' could not be further from the truth; GG Property are a hard working truly lovely bunch and we would highly recommend them.

Latest review:
Works consisted of hip to gable loft conversion under permitted development and a refurbishment of the first floor of a semi-detached house into a four bedroom/bathroom layout, including new windows, balconies, wiring and plumbing as well as sound proofing the walls. With 100m2 of works this was my first introduction to a major building project and I was worried by the horror stories I have heard about builders. From the outset Monika set my mind at rest, listening to what I wanted, making helpful suggestions, offering tips for instance on how to save on the scaffolding and always asking me when choices needed to be made. She took the trouble to ensure that I knew what was happening, with daily photos of progress without the need for me to climb scaffolding. I was working to a tight timescale and budget, which Monika understood, and even having accommodated a number of changes including some additions, the project came in on time and on budget. All of the workers on the site were very professional and the quality of the work and the attention to detail was exceptional. I have no hesitation in recommending Monika and her team - I went into this project apprehensive and not sure what to expect; thanks to Monika, I came out the other side delighted by and looking forward to working with her and her team again to renovate my ground floor.

Latest review:
Fletcher and his team did a 5 metre extension on my kitchen, installed a new kitchen, new doors and new floorboards throughout the downstairs. All members of his team were absolutely outstanding. The workmanship looked extremely professional and it turned out so much better than I expected. If there was ever a problem, it was never a case of ‘we can’t do that’ there was always a solution and I never felt stressed as I knew that whatever cropped up, they dealt with it. They were all so friendly and I felt at ease with them all the time. When I went to work, I left them to their own devices and they always locked up perfectly for me. I can’t recommend them enough and I will certainly have them back when I need more work completing.

Kenny and team did a brilliant job replacing my old lean-to porch area for a new smart extension with windows, door and even a cat flap. They were on time, organised, efficient and took away all the old materials and rubbish. Kenny was helpful when he visited and prompt in replying to all communications and supplying quotes and invoices. I am very happy with their work and wouldn't hesitate to recommend their services.

What can i say, great guys to work with. Came round and quoted as planned. Good competitive pricing. Completed the job better than planned. Always advised and tried to improve on the plans, really have good attention to detail and take so much pride in their work. Job completed bang on time. Never had a issue whatsoever.

Questions to ask local loft conversion companies in Longfield

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 Longfield?

A local loft conversion company in Longfield 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 Longfield 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 Longfield 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 Longfield

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 Longfield before agreeing to start the work.

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

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