Restoration & Refurbishment- 27 Mar 2022
Ricky Reid I was looking for a company who could help me with a light refurbishment (kitchen, bathroom and full decoration) of a one bedroom flat in south west London to be ready for rental within 15 days. I posted my ad request on mybuilder.com and a few companies contacted me. Ricky Reid, was the third one I met and eventually the one I chose. Why? R. was straight forward, no gimmicks and did his best to understand what my needs were from day one. Especially when my vision at the start wasn’t that clear. Him and his team delivered within the time frame agreed as well as within the quote given plus a few extras that hadn’t been considered at the start of the project. He was always available for questions or clarifications needed over the phone at any time! A rare quality in itself in the building world. If there was anything that could be improved, this would be clarifying certain jobs that were on the quote (and I mean specifically what they exactly covered) from the start to avoid stingy or unexpected surprises cost wise. However this isn’t Ricky’s fault and I take my full responsibility as I should have done my homework before hand. Overall satisfied with the result and I would certainly contact Ricky and his team for my next future projects and so should you reading this review. Thank you Ricky and all the best in your company venture.

Restoration & Refurbishment- 16 May 2021
TLC have completed the first phase of the project which has involved a complete renovation and upgrade of the kitchen, bathroom, and rear garden area. A new contemporary staircase has also been fitted. The work has been completed well ahead of schedule, and this is testament to the planning and coordination skills provided by TLC. All of the work has been completed to a very high standard, and a great deal of care has been taken to ensure the minimum disruption to the local residents. We are extremely grateful for the advice and support provided to us leading up to the restoration work and whilst the restoration was underway, and we are absolutely delighted with the final results. Our house has been transformed into a contemporary family home. Many thanks to Bradley, Paul, and the rest of the team at TLC.

Latest review:
Peter was the on-site foreman on our complete house renovation, which took just over a year. This included an additional ensuite pod bedroom in the roof and a side-return and extension to the kitchen. Peter was totally reliable throughout the project and thoroughly professional. Throughout this time we were living in the house with the children. He was always on time, managed the on-site team well and communicated clearly with us. His workmanship is high quality and he was also a stickler for checking the work of others and getting it updated if it wasn’t up to scratch. I have no hesitation in recommending Peter.

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.

Questions to ask local loft conversion companies in Aldermanbury

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 Aldermanbury?

A local loft conversion company in Aldermanbury 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 Aldermanbury 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 Aldermanbury 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 Aldermanbury

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 Aldermanbury before agreeing to start the work.

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

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