Loft Conversion- 27 Apr 2022
Completely Surpassed Expectations! We had Williams and his team in to do some under eaves storage. We had what we had in mind, which they quoted for, and whilst doing the work, they identified better ways of doing things, implemented them and still stuck to the agreed price. As these guys do this more than me, they are able to use that expereince, educate the client and achieve phenomenal results. Great value for money, now i have a large, light and usable storage space where I had next to none, my only problem is finding the stuff to fill it with. They even installed lighting meaning it works that much better. Get them in for a quote, if for no other reason than just to understand your options. His team are hardworking, friendly and do the work with a great sense of humor, taking pride in what they do. Gracias Williams!

Handyman- 24 Sep 2025
I initially called Klodi to repair the kitchen stove extractor pipe, but after seeing their professionalism, I entrusted them with additional tasks, including painting the ceiling and walls in the kitchen and installing a brand new fire door. Throughout the project, they worked quickly and efficiently without compromising on quality. Their team was highly professional, friendly, and very communicative, always keeping me informed about what they were doing and explaining each step of the process clearly. I was impressed with their attention to detail and the care they took to ensure everything was perfect. The finished work transformed my kitchen, and I wouldn’t hesitate to recommend Klodi for any home improvement tasks. Their dedication to customer satisfaction truly stood out. I will definitely use them for more jobs and recommend them.

Restoration & Refurbishment- 19 Apr 2026
Didn’t return to finish the job, respond to calls or messages in response to finishing the job. Sadly wouldn’t hire Ovi & Mihai (O&C) again. Friendly & responsive initially. Worked well, on time, eager to please, did a good job - not perfect but adequate, average attention to detail but corrected when asked. We initially had a faux chimney put in, they touted for more work & provided alcove shelving/cabinet ideas which we subsequently hired them for. They worked intermittently (dad around for first half of job then left for Romania) as this was agreed as best for both parties. However they left the job incomplete once paid (were paid on time, each time, with no bargaining). Didn’t respond to texts or calls, leaving cabinet doors unfinished, large chips & cracks unfilled. Laminate was also poorly cut around hearth stone, left chimney cutout unfinished with no cement to the base. Lack of respect and wouldn’t hire again as cannot trust they won’t disappear. Note previous reviews.

Restoration & Refurbishment- 20 Jul 2015
We hired Zebra Property for a complete strip out and refurbishment of a GF flat. The JOB: The job included initial removal of existing bathroom, kitchen and flooring. The works itself were for a side return wrap around kitchen extension, basement refit, installation of new kitchen and bathroom, new windows (including velux) and bifold doors, tiling and complete decoration throughout. FEEDBACK: Zebra were a great company to work with on this job. Communication levels were clear. There were inevitable delays to the project but there was always a focus to get back on track and deliver as quickly as possible. The resulting finish is a high standard throughout the property, with any minor snags completed quickly. Thank you!

Restoration & Refurbishment- 31 Aug 2015
We have had quite a bit of work on our property in the last few years and the final project was to be our bathroom with the focus around a beautiful copper bath which has been sitting in the spare room waiting to be installed for nearly a year. We needed a company that could deliver a very high standard of work at a competitive price. Top building were not only very fair and competitive but wonderfully detailed in their approach both in quoting and their workmanship which is second to none. Vladimir and team understood the project from day one – made a few trips before hand which built the relationship and made myself and my husband very comfortable with our decision to instruct Top Building. What I enjoyed most is that Vladimir made great suggestions and offered money saving advice. Nothing was too much trouble and I really felt the team got behind the project. The knowledge and expertise is of an exceptional level. We had a few odd jobs that needed to be done which the team (Evo and Dimitri) welcomed and efficiently completed. I very much appreciate the patience and flexibility shown by the team and Vladimir’s brilliant way of keeping us informed every step of the way. Bathroom was totally refurbished including new Walls, plastering, electrics, tiling and new boiler. It really has been a pleasure working with the team – I will most certainly be recommending them.

Loft Conversion- 9 Sep 2018
My brother and I met with many builders when looking to complete our project, a full renovation of our house and loft conversion. When we met with Stephen it was clear from the start that he has huge experience in the industry and we both felt an instance confidence in him, Stephen is a quiet man that lets the quality of his work do the talking. Stephen and his team carried out a complete renovation of the property including stripping out, structural steel installation, new roof, fitting of windows & doors, plastering, decorating, electrical rewiring, plumbing & heating, all carried out with no fuss and to a very high standard. We needed a builder that we could trust with our project as we both work full time and could not be on site every day to supervise the work. Stephen took charge of the project and his communication was excellent, always making a phone call to check any queries and to let us know how things were progressing. He was also happy to suggest changes and improvements to our plans with great vision for what would improve the end result. Minor mistakes were made during the project, but Stephen was always honest and takes a real pride in the work that carries his name, so things were always put right and with minimum fuss. Overall we feel very lucky to have found such an honest, hard working and reliable builder, we would not hesitate to recommend Stephen and if we ever carry out another project, he will always be the first man we would go to for a quote.

I had my double side and single rear L shape Extension which had kitchens and bathrooms with bedrooms. It was turnkey project and didn’t know them before but they are Pro Contractor as they got all planning permission approved with structural calculations. They completed work in time with high standard quality and regulations and got my certificates from council. I would recommend them as Pro builder all the time.

Questions to ask local loft conversion companies in Upper Tooting

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 Upper Tooting?

A local loft conversion company in Upper Tooting 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 Upper Tooting 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 Upper Tooting 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 Upper Tooting

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 Upper Tooting before agreeing to start the work.

Do I need planning permission for a loft conversion in Upper Tooting?

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