Loft Conversion- 23 Apr 2019
A very positive experience. We are not going to say everything was plain sailing. We got there in the end. Arick & Greg, the joiners were especially brilliant. Office communication could be improved at times and the office could be more pro-active. All of the others Duanne, Wesley and Rocky were great. There are a few things ourselves we have to do but now have a extra room in which to live and work. The guys put in long hours and put up with interruptions from our three dogs. Arick & Greg work incredibly hard and put in long hours ; much more then perhaps anyone else we have seen. It is always difficult dealing with things at a distance and we appreciate the office sorting things out when minor issues have arisen (we know they have changed some of their procedures because of us!). Overall it has been a very positive experience. Just glad that soon things will be completely finished and our new floor will no longer be like a building site. We believe we have added value to our house with the help of econoloft and our looking forward to moving in soon.

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.

The guys did a superb job! Not only did they make everything I asked for a reality, they also guided me through decisions when I needed help. They put extra hours in to make it happen on time and I could not be happier with what feels like a brand new home. They were a pleasure to work with and we were great at communicating the progress giving me a peace of mind throughout the project.

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!

Questions to ask local loft conversion companies in Charterhouse

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 Charterhouse?

A local loft conversion company in Charterhouse 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 Charterhouse 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 Charterhouse 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 Charterhouse

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 Charterhouse before agreeing to start the work.

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

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