When Mr Nesimi came to undertake a pre-assessment for my front wall, he came across very professional and genuine and very honest about the work needed doing. He even suggested some changes to the work to reduce cost. The quote he gave me for the job was very reasonable and he was able to slot in my job within a week and arrive sharp on time at 8am and got on to the job straight away as I had a busy day at work for me to attend to. I notice that right from the start he was very clean and meticulous with the work and his job was of a very high quality ( compared to a job I had done by another builder 9 months ago). My neighbours also noticed this difference and were praising Mr Nesimi’s work. I would definitely recommend Mr Nesimi for any construction work as I felt he was very professional, reliable and honest and most of all the work was of high quality. I will be certainly calling him for my next job, most likely the driveway resurfacing and the attic conversion within the next year.

Restoration & Refurbishment- 6 Oct 2025
Rich and the team have done a fantastic job completing my kitchen and hallway renovation. His team guided me the whole process and were great communicators. No problem was too big or small to handle. There were some issues through the job (due to the initial poor design of the kitchen when it was first built) but the team were quick to resolve this professionally. I would not hesitate for a second to recommend Lux Contracts. Next year, I will be booking them for the rest of the flat! I’m happy to be contacted by prospective customers if any further information is needed. Rhys Gallagher

Extensions- 8 Dec 2021
Me and my wife are very satisfied with Prabbuilders work. What stands out with Prab builders is that they do every task as if they are doing it for their own house and with work they are meticulous and exceptional. What we started with and how our extension looks now is simply amazing and the way they explain about what will look good(Color/ the structure etc ) is commendable as we both were not sure what decision to make, but after completion we are overjoyed to see how excellent it turned out to be now. I would recommend them anytime based on their skill ,eye for detail, being punctual and the hard-work they invest into every task to make sure we are getting the final product the way we dreamt of.

Extensions- 28 Oct 2018
We appointed HWB to carry out a full refurbishment on our house, this involved re-gutting the interior and building an extension and loft conversion plus some landscaping in the garden. We spoke to many builders but finally appointed HWB based on their previous projects and professionalism. Appointing builders for any work is always difficult however we are delighted that we went with HWB. Throughout the project they have demonstrated high levels of professionalism, were very organised and worked to very high standards. They were collaborative throughout the whole project and kept us informed at every stage. As the project developed there were some changes made and HWB were flexible and open to new instructions made by us, as well as giving us valuable advice. Farag, Ayoub and the HWB team were always available to answer any questions and provided us with constant feedback on progress as well as identify new solutions to aid the development. They have a great team of workers who work to a high standard and are supervised throughout the project. We made the right decision going with HWB Construction and have no hesitation in recommending them.

Restoration & Refurbishment- 17 Jul 2016
Valter was very impressive on his initial visit with some exciting ideas for the house improvements and we had no hesitation in choosing Happy Building above the other two building firms who quoted. Having signed off on the budget and scope of work, Valter's team of builders arrived. We were hugely impressed with the skill, experience and work ethic of the team; the fact that they arrived early each morning smiling underlined the "Happy Building" epithet; Jarek, the site foreman, had an especially cheery demeanour. The work involved stripping the walls back to bricks, removing walls, reinforcing foundations, plastering, extending the bathroom and removing one bedroom to create a large ensuite bedroom. The latter certainly would not have been done without Valter's vision and patience in explaining how it would look. We were able to deviate from the original plans without any problem which was very important in achieving the final look which we had desired. Valter was very careful in sticking to time and budgets which I had never experienced before with builders. The kitchen, bathroom, two bedrooms, living room and hallways were finished to the highest possible specification within our budget. There were one or two small features which, with hindsight, we would have improved such as door handles and shower fittings, however this was down to us not specifying exactly what we wanted. These are very minor details and a tiny part of the overall picture.

Questions to ask local loft conversion companies in Aldersgate

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 Aldersgate?

A local loft conversion company in Aldersgate 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 Aldersgate 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 Aldersgate 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 Aldersgate

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 Aldersgate before agreeing to start the work.

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

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