Carpentry- 10 Sep 2016
I'm just discovered that through some oversight I've neglected to leave feedback on this job - replacing an old garden pergola, quite a large one. Lucas and his colleagues did excellent work and we were very happy with everything. We would certainly hire him/them again - if he's not too booked up, that isc! Highly recommended. Christopher Sykes

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.

I recently had a full house refurbishment completed by KKR Builders Ltd, and I am extremely satisfied with the results. The project included a complete bathroom renovation, full house rewiring, plastering, painting, and replacing all doors throughout the property. All work was carried out to a high standard with great attention to detail. The bathroom looks fantastic, and the plastering and painting have completely refreshed the home. The new doors have added a modern finish throughout. A special highlight was the beautiful temple they built for me — it is truly stunning and crafted with great care. The team was professional, reliable, and easy to work with from start to finish. I would highly recommend KKR Builders Ltd for any full home refurbishment.

Loft Conversion- 10 Nov 2016
Paul and his team were able to complete the work within the 6-8 week timescale. They were efficient, clean and overall very pleasant to work with. This was our first renovation project so I was really nervous given all the horror stories you hear about builders but Paul was superb to work with. He kept us in the loop throughout the build and if there were any issues he made sure they were dealt with them without troubling us too much. The quality of their work is outstanding and we are so pleased with the turnout. We had a few add ons to the job which Paul accommodated and nothing seem too much for him and his team. He is highly recommended and we will be calling him to come back and do further work on our house.

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.

I am extremely pleased with the loft conversion completed by Mr. Jasvir and the team at Naksh Construction Limited. They transformed our unused loft space into a beautiful self-contained studio apartment, including a bedroom, bathroom, and kitchen area. The team carried out all the work exactly as instructed and made excellent use of the available space, ensuring the layout was practical, spacious, and comfortable. They also installed cupboards and storage solutions that fit perfectly and enhanced the overall appearance of the studio. The quality of workmanship was excellent throughout, and the finished result looks fantastic. The team was professional, reliable, hardworking, and kept us informed during every stage of the project.

We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.

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!

Questions to ask local loft conversion companies in Chessington

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 Chessington?

A local loft conversion company in Chessington 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 Chessington 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 Chessington 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 Chessington

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 Chessington before agreeing to start the work.

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

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