Kitchen Fitting- 30 Jul 2023
I had a wonderful experience with Lanigans construction. Reece, Rob, Mike and the team did an extremely great job on my project which was my new kitchen, roofing, stairs, painting and decorating the whole house. There high attention to detail and quality sets them apart from the rest. They were always cleaning up after themselves, leaving the site neat and tidy. They were also very friendly and courteous, always listening to my needs and preferences. They were professional, reliable, and honest. I would highly recommend them to anyone looking for a builder who can deliver excellent results. Thank you for your amazing work!l

Carpentry- 16 Apr 2017
For a number of reasons, Reinaldo is without doubt the best tradesman I have come across, After having Cowboy Builders ruin my brand new doors. The quality of his work was faultless, he was prompt, always on time and very efficient, his work and work area was always left clean and tidy, and his communication skills, with regards to problem solving and making sure that the work he was carrying out was to my requirements, was excellent. I gave Reinaldo a number of jobs to do over a few separate visits and was not let down once. I cannot recommend Reinaldo highly enough and will be using him again for any future carpentry & joinery works. Reinaldo is not a carpenter however a magician as he can spell his Magic on any given work with a smile.Thanks again ,Reinaldo great work!

Blueline completed the work to the exact high standard i was hoping for, while remaining on budget and estimated timescales - the three things that were most important to us! They were punctual, practical, knowledgeable and willing to give advice when either needed or when something could potentially be improved. They were always available to talk through what was happening at every stage of our job, with any complications arising, and importantly solutions to any problems. They knew their stuff and got the job done without any hassle either. They even came back after the job was finished to shift some pipework which i had an extra requirement for. The best feedback i could give is that we will go straight to them for any work we require in the future, and have already recommended them to friends.

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.

Conversions - General- 15 Apr 2026
Luke and Diti are both amazing guys for this project. Honestly speaking they aren't the cheapest quote, but they are definitely beyond expectations. Luke was the only builder who gave a full transparent quote on each item and what was needed for the conversion. Really quick work and good planning because I have 2 cats and they did everything with enough people onsite to minimise the time. Speaking of work, it is good, we kept in communication and they were always happy to explain and adjust slightly according to my concern/question. Leave this comment after the work has been done for few months and everything is solid.

Questions to ask local loft conversion companies in East Finchley

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 East Finchley?

A local loft conversion company in East Finchley 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 East Finchley 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 East Finchley 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 East Finchley

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 East Finchley before agreeing to start the work.

Do I need planning permission for a loft conversion in East Finchley?

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