Extensions- 11 May 2018
After a rogue builder left me with 18 (eighteen) structural issues. Lez and his crew came in transformed my failed extension into a masterpiece. All aspects of the job was done to the highest quality and utmost care and attention to detail was shown to building control needs. They cleaned up after every day and made sure the house was habitable, as I had to live there. Every aspect of the build, from the carpentry, plastering and tiling was first class and their recommend electrician and plumbers were from the same stock. Total professionals. My only regret is that I did not use this builder the first time. The prices were reasonable and even building control had good word to say about their work. Thanks Lez

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.

Bathroom Fitting- 14 Jan 2015
Highly recommended. Work was done on budget and on time. Narcis and Levi always happy to help and listen to any queries and adapt as the job went on. Left the place clean at the end of each every day. We had a small leak under the sink after the job was finished which was sorted out promptly. The finish (painting/tiles etc) was of decent quality. Bathroom was completed 6 months ago and no problems since.

This builder works really hard and time efficient. He has helped transform my house into a luxurious living space and I am not exaggerating when I say that the price is very fair, I have had three times the quotes for less the quality.

Landscaping- 16 May 2026
Very professional quotation, I chose over two others because he was very clear on where extra costs may arise and was very straightforward. He advised a different finish than I originally thought I wanted with cut stone edges and it looks even better with his suggestions. His crew were very friendly and professional. Would definitely work with him again in the future.

Restoration & Refurbishment- 25 Sep 2025
We were over the moon with our kitchen once Zihni and his team had finished. We had never used this firm before but we will definitely be using them again for future projects. Zihni is calm, knowledgeable, and went over and beyond in helping us not just complete our kitchen project, but in helping us move into a new home smoothly. We are also really appreciative of the rest of his team, as they were all so serious, professional and perfectionists. Zihni's communication was probably the single reason why the completion of our kitchen was such a success.

Questions to ask local loft conversion companies in Stockwell

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 Stockwell?

A local loft conversion company in Stockwell 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 Stockwell 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 Stockwell 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 Stockwell

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 Stockwell before agreeing to start the work.

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

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