Extensions- 17 Aug 2026
I had a very poor experience with this contractor and would strongly advise potential customers to be cautious before paying substantial sums in advance. I paid £3,672 by bank transfer following an invoice for the supply of structural steelwork. There were significant delays and communication issues, and the steel was not supplied to me as agreed. After giving him opportunities and clear deadlines to resolve the situation, I terminated the agreement and had to make alternative arrangements to keep my project moving. Most concerningly, despite my requests, the £3,672 I paid has still not been refunded as of the date of this review, and I am now pursuing the matter formally. Based on my experience, I cannot recommend this contractor. I would advise anyone considering using his services to be extremely cautious about making advance payments. I will update this review if my £3,672 is returned.

Carpentry- 16 Apr 2017
For a number of reasons, Reinaldo is without doubt the best tradesman I have come across, After having Cowboy Builders ruin my brand new doors. The quality of his work was faultless, he was prompt, always on time and very efficient, his work and work area was always left clean and tidy, and his communication skills, with regards to problem solving and making sure that the work he was carrying out was to my requirements, was excellent. I gave Reinaldo a number of jobs to do over a few separate visits and was not let down once. I cannot recommend Reinaldo highly enough and will be using him again for any future carpentry & joinery works. Reinaldo is not a carpenter however a magician as he can spell his Magic on any given work with a smile.Thanks again ,Reinaldo great work!

Carpentry- 17 Jun 2026
I cannot recommend Atilla highly enough. I originally brought him in to help with the carpentry work on my house build following a full demolition. The plan was for him to assist for just a few weeks, but from day one it became clear that he was exceptional at what he does. He was reliable, hardworking, highly skilled, and always polite and professional. As the project progressed, I ended up keeping him on for the entire duration of the build—around seven months. During that time he worked alongside various contractors, carpenters, roofers, and other trades, consistently proving himself to be one of the most dependable people on site. He became involved in virtually all aspects of the carpentry work throughout the project and always completed tasks to a very high standard. His attention to detail, positive attitude, and willingness to help wherever needed made a huge difference to the success of the build. Thank you Atilla.

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.
