Pawel and the team did a fantastic job. The bathroom looks superb and the whole team took time to finish the job to a very high standard. There was a narrow timeframe in which to do the work and this was met (despite more effort than first thought with respect to strengthening the floor). Pawel was easy to deal with and contacted me after the job to ensure everything ok. Highly recommended.

Restoration & Refurbishment- 19 Apr 2025
Positively, certain aspects of the finishing, particularly tiling, were carried out to a good standard. However, the overall experience was mixed due to significant issues. There were notable challenges during the project involving basic logistics and site management, leading to considerable inconvenience that seemed avoidable. Furthermore, the quality of workmanship was inconsistent; while some parts were good, other areas involving fittings and fixtures showed a lack of attention to detail in the finish, requiring later adjustments. Communication during the process could also be difficult, particularly regarding problem-solving and planning for materials. While we appreciated the parts done well, the project was let down by these inconsistencies and process issues, leading to some ongoing snagging and disappointment.

Extensions- 11 Jan 2018
This was our first project, and we were exceptionally fortunate to find Bujar. We're actually getting tired of hearing our family and friends tell us how lucky we are and how amazing he sounds. One of the most honest, trustworthy, and genuine people I've ever met. If I had a problem, he'd be one of the first people I'd call! In fact I did last week and he came to the rescue :) His team were all friendly, polite, conscientious and very tidy. They worked around us as much as they could, always making sure we had access to what we needed which sometimes meant it took them longer to work. Bujar is a perfectionist and is so proud of what he does, he made sure everything was done to a high standard - the estate agent who came round after we were done was impressed! His prices are very fair (better value than other quotes we got and much less time). We couldn't believe it was done in the 3 months he said it would take, and we managed to fit in a few extra bits and pieces after that. He was so helpful throughout, took all project management on and didn't bother us unless an important decision needed to be made. He drove us around all over the place to sort kitchens, bathrooms, etc. and gave us really helpful advice throughout the process. Highly recommend him and his team. I can't imagine ever wanting to look for another builder unless I had to - something that is quite common amongst Bujar's clients. We are extremely pleased with everything about our new house.

Questions to ask local loft conversion companies in New Southgate

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 Southgate?

A local loft conversion company in New Southgate 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 Southgate 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 Southgate 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 Southgate

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 Southgate before agreeing to start the work.

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

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