Loft Conversion- 31 May 2022
I agreed a price and schedule of works with Muli (Flamur Marku). The day before, he changes the start time from 9am to noon. On the day, I call him at noon, to ask if he is still attending. To which he replies, "I was just about to call you, I'll be there in an hour". I say to him that it is not a good start to our business relationship. That he should at least have informed me that he would not be attending. He said, just forget it then, and put the phone down. I want to warn other customers of his potential short comings, and to have other potential builders on hand.

Plastering- 4 Oct 2024
Mr Rifat did an excellent job for plastering rooms and i would recommend him to everyone highly. The work he has done is to a very high standard and completed in 3 days. His quote was very helpful and comprehensive and he was helpful and very kind and calm. He did not take a break from doing the work, even though i told him to take a seat for 5-10 minutes. He is a very hardworking person. I think anyone to catch him to do a job for themselves is very lucky. I recommend him to everyone because he knows how to do good job.

Ahmad and the Beam Developers team did an amazing job on my rear extension. We were very particular with our requests and are generally picky people but they were very patient and accommodating to our every request. We were shown the drawings, made adjustments and managed to tailor the project exactly to what we wanted. The finished results were amazing. No big project for us soon but should we plan to do the loft will definitely use Ahmad and his team again.

He fully explained the procedure from start to finish was always on time and tidied up at the end of each day.His work is second to none and the price was very very competitive in fact much less then the big companies were asking.I am extremely happy with the job and the standard of finish.

Restoration & Refurbishment- 8 May 2012
We hired Audrius initially as his quote was very competitive and I felt confident with his knowledge and practical approach to repair our roof, this was to remove all the slate tiles, lay new felt, new batons and replace with as many usable original tiles, this was organised and completed with as little disruption as possible to ourselves and we were highly pleased with the finished roof. We discussed further renovation works we wished Audrius to carry out so work continued with loft conversion, basement conversion, chimney brests removed, new boundary wall, replastered ceilings throughout, his team were polite and always cleared away when they left for the evening and they were always early in the morning. All problems were sorted quickly and the best solutions found always with costs kept to a minimum, we also changed things here and there and Audrius always had excellent ideas which would save costs and keep our budget in check. Audrius and his team are professionals and we have other work for them in the future and will not be using anyone else.

We recently had our bathroom refurbished by Cubitt Wren in London, and we couldn't be happier with the result. From start to finish, they were reliable, professional, and always turned up when they said they would. The work was completed quickly without compromising on quality, and the whole team was polite and respectful throughout. Communication was excellent the entire way through. They kept us updated at every stage, answered any questions we had, and made the whole process stress-free. The finished bathroom looks fantastic, and it's clear they take real pride in their work. I would definitely use Cubitt Wren again in the future and wouldn't hesitate to recommend them to anyone looking for a reliable and skilled company.

Questions to ask local loft conversion companies in New Wanstead

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 Wanstead?

A local loft conversion company in New Wanstead 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 Wanstead 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 Wanstead 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 Wanstead

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 Wanstead before agreeing to start the work.

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

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