Restoration & Refurbishment- 18 Feb 2021
Ray was an absolute professional. He fitted a new downstairs toilet which required a new soil pipe and associated groundwork as well as new stud walling to partition the space. He did most of the work himself, but brought in others for the pieces where he wanted an expert. He was flexible to small changes and was happy to take on additional work when unforeseen issues were discovered. The areas he had worked in were quickly cleaned before he left each day. Overall the work was completed to a good quality and at a reasonable price.

I received quotes from multiple builders to build a garden office, and choose Teodor as he provided the best quote. His workmanship is top quality and he built me a fantastic garden office which I am enjoying immensely. Teodor was very professional and reliable, keeping me involved throughout the whole project.

Loft Conversion- 29 Apr 2023
My house was totally renovated by this company. I was very satisfied with much of the work. I was informed that I would be given the buildings certificate and the electrical certificate for works completed once final payment was received. I was given the buildings certificate. I was not given the electrical certificate, although the house had been fully rewired as part of the work. I chased up for the certificate but my requests were ignored. I was aware an electrician had come to inspect the works, and the builder who had been on site indicated it appeared to go well. I have now just recently had the electricity in the house inspected by an electrician and have found there were issues that required rectifying.

I recently had a full kitchen installation carried out and I’m really pleased with the results. From start to finish, the work was completed to a high standard and everything was done with great attention to detail. The installer was professional, punctual, and easy to communicate with throughout the project. Any issues or questions I had were dealt with quickly and clearly, which gave me confidence that the job was in good hands. The workmanship is excellent – everything is level, neatly finished, and exactly as discussed. They also kept the workspace tidy each day and made sure everything was cleaned up properly once the job was complete. The kitchen looks fantastic and has completely transformed the space. I would happily recommend them to anyone looking for a reliable and skilled kitchen installer, and I would definitely use them again for future work.

Bathroom Fitting- 10 Jan 2025
I have no hesitation in recommending Shri Krishna builders - Gagan, and his team Nitin and Sonu for all building works. I initially requested a new downstairs toilet, but they utilised their expertise for other works - a new bathroom and electrical works throughout my house. I found their work to be of a high standard, and equally importantly their manner was trustworthy, obliging - no job was too small or too big, and they were very helpful with their guidance on materials and ideas. I am sure our paths will cross again, when I next require a builder.

Questions to ask local loft conversion companies in New Malden

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 New Malden?

A local loft conversion company in New Malden 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 New Malden 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 New Malden 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 New Malden

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 New Malden before agreeing to start the work.

Do I need planning permission for a loft conversion in New Malden?

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