Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

Carpentry- 2 Feb 2022
I used Crown Carpentry for the first time and found Nick to be very good at his work. He knew exactly what needed doing with the three internal doors we had problems with. We thought two of them would need replacing but Nick was able to fix them quickly and securely with no need for replacement which we were very pleased with! His work was tidy and he thoroughly cleaned up at the end of the job. It took as long as Nick had estimated, he charged accordingly and at the price quoted. We were very pleased with Crown Carpentry and will be using them again if needed. I would highly recommend them to anyone.

We hired Sam to build us some shelves and storage units in our two alcoves. He was very professional throughout and performed an excellent job whilst keep the house clean and tidy considering the weather conditions. He even assisted with extra design elements that were not part of the original scope. Overall the work was done on time, to the amount quoted and to a high standard. A very friendly and helpful service and always willing to go a step further than required. We would recommend Sam if you require any sort of carpentry assistance around your home.

Questions to ask local loft conversion companies in Kennington

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 Kennington?

A local loft conversion company in Kennington 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 Kennington 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 Kennington 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 Kennington

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 Kennington before agreeing to start the work.

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

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