Kitchen Fitting- 7 Jan 2021
My experience with Leszek was entirely positive and I wholeheartedly recommend him. I had recently moved property (converted victorian flat) and required a new kitchen installed, shelves built, radiators replaced, painting throughout and some changes to electrics. The work was undertaken around October 2020. Leszek completed the work to a very high and professional standard and I am really happy with the end result. He was easy to get on with, good natured and commutative which made the whole process easy and less stressful for my first experience in home improvements. Leszek was always happy to answer all my questions and further explain the fine detail from electrics to kitchen installation. When small problems arose, he always had a couple options ready to discuss and called promptly to keep me up to date. The kitchen installation is perfect which also included tiling a backsplash. Lezek built some lovely selves in the recesses either side of my fireplace which look brilliant and very smart. The painter and his work was really professional and speedy. Snagging was dealt with and two neighbours independently and proactively commented that the work was done with minimal disturbance to them. From quote to completion it was all in all an excellent experience!

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.

Carpentry- 7 Nov 2013
Ervins done a great job. The wardrobe is now repaired and sturdy. In fact it is much more solid than it was before. He was also able to attend at short notice as everything had been taken out of the wardrobe so needed the job done urgently. Would not hesitate to use him again.

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.

We had the pleasure of working with Alfa Style Limited on our loft conversion and we can recommend them highly and without reservation. Their work is incredible, attention to detail outstanding – our build was done with care and precision. They turned up on time every day, worked incredibly hard and quickly. In addition, they were extremely clean and tidy in the workplace – they never left the worksite in disarray. This is the first time we have done such a big project – Ruslan, Slava and their team were amazing. They were brilliant at explaining what was going to happen, day by day, week by week and translated the more technical information! No question or query was too much. The service after the build had finished has also been great, calls to check everything is OK and any queries we have, they are only a phone call away. We have had so many compliments from family and friends who have seen the finished build … it has made a huge difference to our house, we could not be happier.

Amazing guys. Hardworking, tidy, professional. They worked in our house for 3 months and we were super happy with the work and everything. We invited them to do more work later on. 100% probably the most sincere and trustworthy builders we met. Only them. No one else from now on.

Questions to ask local loft conversion companies in Banstead

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 Banstead?

A local loft conversion company in Banstead 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 Banstead 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 Banstead 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 Banstead

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 Banstead before agreeing to start the work.

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

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