I had asked Lee to build me a media wall with a shelf behind the TV so the Sky Box could sit behind it, I also had asked for an electric fireplace to be fitted underneath the TV. Lee was so helpful leading up to the work being done and was always very quick to respond to any question I had. The wall looks incredible it’s everything I asked for and more. It’s so neatly done and I’ve had so many compliments on it already. Lee was so professional and everything was completed very efficiently. I am in love with it and would definitely recommend Lee and his team to everyone.

Loft Conversion- 14 Oct 2021
Zilvinas produced drawings promptly and at a very competitive rate. He attended several site visits and ensured to incorporate all of our ideas. We have received fantastic after sales service from GoldBerg Engineering throughout the project and would not have had the results we have, without Zilvinas. Goldberg Engineering has provided brilliant guidance throughout, through rapid response emailing, regular Skype and several site visits. Goldberg approved each work phase and continues to offer support. Thank you very much! Highly recommend, 5Star!

Restoration & Refurbishment- 1 Feb 2026
The WORST experience I have ever had with a tradesman. I would strongly advise others to stay clear. There was no schedule of works at any stage. Adrian failed to plan, failed to communicate agreed works, & did not even tell his own workforce what they were meant to be doing. There was no evidence of professional oversight or management, resulting in chaos & extreme delays. I was repeatedly misled. He stated that Building Control had been contacted & paid for; but when I contacted them directly they confirmed no application or payment had been made. He damaged my property & instructions were ignored. He was rude, aggressive & shouted at me in my own home, which I found intimidating as a woman. Neighbours also complained about his behaviour. Despite multiple extensions, the job was left unfinished with little communication. He caused significant stress & a serious loss of time & money. The matter is now being resolved through the courts. I would NOT recommend him under any circumstances

Hard Flooring- 23 Feb 2020
Andrei provides great communication and very professional service. He was very flexible and worked extremely hard to get all the work done in the shortest time possible, but he did not compromise on quality. He worked very efficiently and considering all the work he had to do, he still left the house clean and tidy. The attention to detail was second to none. I’m extremely happy with my new flooring and would definitely recommend.

I’m a fully experienced carpenter based in Kent with over 18 years in the trade, established in 2007. I cover all aspects of carpentry and general building, specialising in first fix work and loft projects including loft conversions, extensions and roof construction. I also undertake decking, fencing and structural timber work, along with smaller building projects and repairs. I now mainly focus on small to medium sized jobs, so I’m happy to help where bigger firms often aren’t interested. I take pride in tidy, reliable workmanship and practical solutions built from years of hands-on site experience. I’m always happy to offer advice and discuss options before work begins. Photos of previous work are available on request.

Loft Conversion- 2 Jul 2016
Top finish were ultimately hired to conduct this work. There was admittedly some job creep in this project. Alan came round and discussed our intentions and suggested a possible route forward. An architect (Red Squirrel Architects) was independently retained by us to work with the Top Finish team to deliver a Dormer conversion reorganization and significant structural works for a side return extension and installation of a new kitchen (13 steels were inserted and a sewer had to be bridge over, with permission) The job was completed to a high specification, particularly given some of the problems thrown at the team when dealing with a 150yr old property. I think it's important to understand that when undertaking jobs of this scale, and if you are planning to live in the property as we did, then you are effectively living with the team you chose. To that avail- ALL of the top finish team were always considerate and a pleasure to be around and happy to fix any concerns rapidly as required. I wish Alan and his team all the best going forward and I would recommend meeting Alan and including him in your shortlist for any job - large or small.

Conversions - General- 25 Nov 2019
Unreliable and ultimately completely let down by this builder. Very responsive during quote stage but when agreed start date approached no contact, upon chasing he advised of a weeks delay. Again no contact from builder and despite confining another start date and time no start or contact from builder. Having again agreed a third date, on the morning they were due to start we received an email cancelling agreement in totality. For the sake of completeness the specification of the job did change from that first posted but up until the time came to actually start he remained keen to undertake the work.

Restoration & Refurbishment- 8 May 2012
We hired Audrius initially as his quote was very competitive and I felt confident with his knowledge and practical approach to repair our roof, this was to remove all the slate tiles, lay new felt, new batons and replace with as many usable original tiles, this was organised and completed with as little disruption as possible to ourselves and we were highly pleased with the finished roof. We discussed further renovation works we wished Audrius to carry out so work continued with loft conversion, basement conversion, chimney brests removed, new boundary wall, replastered ceilings throughout, his team were polite and always cleared away when they left for the evening and they were always early in the morning. All problems were sorted quickly and the best solutions found always with costs kept to a minimum, we also changed things here and there and Audrius always had excellent ideas which would save costs and keep our budget in check. Audrius and his team are professionals and we have other work for them in the future and will not be using anyone else.

Questions to ask local loft conversion companies in Longfield

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 Longfield?

A local loft conversion company in Longfield 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 Longfield 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 Longfield 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 Longfield

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 Longfield before agreeing to start the work.

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

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