Bathroom Fitting- 20 Sep 2017
We hired Luca for a job that involved a variety of work across our entire flat. Being totally new to renovation work and having been stung by other builders, meeting Luca was a breath of fresh air – he was friendly, helpful and honest. Luca did an great job for a very reasonable price. He’s fairly new to contracting bigger jobs, but he’s got a lot of previous experience as a tradesman and his plastering in particular was perfect – we’ve had loads of compliments on the quality of his walls and ceilings. He was always on time, always communicated with us fully, and was a pleasure to have around the flat. He made a real effort to keep disruption as minimal as possible and was very patient with us about stuff needing to be moved from one place to another. It wasn’t the easiest job and there were a couple of problems and extras, but Luca takes a lot of pride in his trade and worked extremely hard to keep us happy. We had a couple of plumbing issues arise but he went well above and beyond to resolve them, coming back for 2 days after the job was due to be finished to make sure that everything was working properly. This is far more than we expected, and we did really trust that Luca wasn’t the sort of person that would leave anything unfinished. We’re so chuffed that we met Luca and with the excellent work he did, and would love to work with him again. Luca is going to go on to big things, so if you get the chance to hire him now, we'd recommend him without hesitation.

Loft Conversion- 7 Sep 2020
JMD demonstrated the upmost professionalism in delivering this one of a kind Architect designed roof and kitchen extension. They delivered on budget, communicating clearly any problems and agreed additional costs as the project went on. The project presented a very difficult logistical problem with limited access which JMD handled with great care and consideration in difficult circumstances. The whole team have remained positive, friendly and helpful throughout one of the most testing times in living memory. Covid extended the period of work beyond anyone's control, but JMD managed the situation dilligently and through sheer hard work reduced delays as best they could. We are absolutely delighted with the finished product which ended up better than we could have imagined when we started. It looks stunning. Well done to everyone who worked on it.

Loft Conversion- 22 Aug 2024
From start to finish, we had a wonderful experience with Alin of Smart Builders. He took us a show some of his previous work and we felt confident in giving him the job of our loft conversion and garden gym building. He has a team of hard-working professionals and they made the job go very smoothly and efficiently, from day one. He started his timeline and even though we had small issues along the way which is to be expected he always had a solution or more than one solution for us and was mindful not overspend on our behalf. Honestly, we could not have asked for a Builder and the end result is really beautiful. The team were very friendly and polite and cleaned up behind themselves every single day. I wouldn’t hesitate to recommend Alin to anyone who is lucky enough to book him for their job.

Questions to ask local loft conversion companies in Twickenham

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 Twickenham?

A local loft conversion company in Twickenham 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 Twickenham 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 Twickenham 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 Twickenham

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 Twickenham before agreeing to start the work.

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

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