Jo and his son have been fantastic. The job has been completed to a very high standard - looks much better than I could have envisaged. The pair have also been a pleasure to have around. I can wholeheartedly recommend them. Jo was able to advise on what would be best (as we had no clue!) There is no way we could have completed this job without Jo's knowledge and expertise. Jo will always be my first port of call. Thank you for all your hard work.

Works consisted of hip to gable loft conversion under permitted development and a refurbishment of the first floor of a semi-detached house into a four bedroom/bathroom layout, including new windows, balconies, wiring and plumbing as well as sound proofing the walls. With 100m2 of works this was my first introduction to a major building project and I was worried by the horror stories I have heard about builders. From the outset Monika set my mind at rest, listening to what I wanted, making helpful suggestions, offering tips for instance on how to save on the scaffolding and always asking me when choices needed to be made. She took the trouble to ensure that I knew what was happening, with daily photos of progress without the need for me to climb scaffolding. I was working to a tight timescale and budget, which Monika understood, and even having accommodated a number of changes including some additions, the project came in on time and on budget. All of the workers on the site were very professional and the quality of the work and the attention to detail was exceptional. I have no hesitation in recommending Monika and her team - I went into this project apprehensive and not sure what to expect; thanks to Monika, I came out the other side delighted by and looking forward to working with her and her team again to renovate my ground floor.

Carpentry- 1 Jul 2019
Giles is a very capable carpenter/builder and in the end I was overall ok with the work done. However, his behaviour and care of property left a lot to be desired. He has no customer service skills and the loudness and nature of conversations were not appropriate in a small cul de sac. Despite being asked many times by myself and even his fellow workman he continued to shout and use inappropriate language. The thing that upset me the most was just the lack of professionalism and respect for property. The work required lots of sawing and cutting of tiles. This was done all over my garden lawn and has virtually ruined it, no work sheets under the work table to stop stuff going over lawn. Paint over floor and grass, cig buts everywhere, dried cement left all over road. To be fair Giles did offer to come back and sort stuff out after I had pointed stuff out to him but to be honest I don’t want him back here. He could not sort lawn anyway and I am having to get gardener to sort. He has left bags of sand at front of property which he promised to collect - they have been here for days now. There are other issues which I will speak to My builder directly about. It’s a shame actually because I can see that Giles is actually a pretty amazing carpenter and builder. If he can sort out the other issues I reckon that he will become a top rated.

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.

Questions to ask local loft conversion companies in Tonbridge

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 Tonbridge?

A local loft conversion company in Tonbridge 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 Tonbridge 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 Tonbridge 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.
