Frazer completed our loft conversation for us and we cannot recommend him highly enough. Nothing was ever too much trouble and his skill-base in what he does is very impressive. The work he carried out for us in the end ranged from a loft conversion with en-suite to the removal of two walls on ground and first floor and even re-laying solid oak flooring throughout our ground floor for us too. Not only did he do the work above but he helped us achieve our dream space by being so amenable to our requests to make adjustments as we went along, even creating a bespoke crafted skirting board so that we could have our picture window at the height we wanted. In addition he designed and created beautiful fitted wardrobes into our eaves space and wooden windowsills through-out using wood we had sourced and wanted to use. Throughout the work he was always professional, considerate and communicated continually with us around what we were wanting. He stayed with us the entire time, focused on getting our job completed rather than jumping onto other jobs and he worked so hard every day, always available throughout the work taking place if we needed to check anything. What we appreciated the most from Frazer was how regularly he communicated with us about what was coming up so that we could make the decisions we wanted to make along the way, without feeling as though changes were being made outside of our preferences. The work being done was made to feel very easy from our side where Frazer is so experienced and self-directed, arriving promptly every morning and working hard all day whilst always being open to talking anything through whenever we wanted which was so reassuring for us. Frazer is professional and warm as an individual and we were really grateful for how he communicated and liaised so politely and considerately with our neighbours throughout the work. He is always happy to be guided by his customer which we found a huge benefit as we often had our own ideas of what we wanted but when we encountered problems we found him to be very creative and he often found solutions to problems that we hadn’t thought of. He suggested using the dead space we had in our en-suite to create a tiled recessed space for our toiletries and also suggested adapting another dead space in the bedroom by making a hidden shelving space which has been invaluable to us as we work from home. Frazer’s work ethic is instantly evident and by working as hard as he did every day it meant that he finished the job ahead of schedule which we were so grateful for. We are utterly delighted with the work he has done for us and we have requested him back since to do some additional smaller jobs. As someone who is extremely reliable and skilled, we wouldn’t hesitate to recommend him to anyone needing work done.

Loft Conversion- 7 Aug 2019
When we invited Rae into our home to view the possibility of what we might be able to achieve, we were extremely impressed by the extra scope and insight he gave us. It went far beyond what we envisaged and he was able to create a lot more living space for us. When you undertake a project this big you never really know how it will appear as a final result, Rae was able to deliver a brilliantly finished loft conversion and keep our peace of mind throughout the whole project. When we look at it now we really can't believe what we have gained! Much more than we expected and I think this was the most impressive thing about choosing Rae and his talented team, it was that they were able to go the extra mile to get everything out of the area being worked with! Its that personal touch that made us ask Rae back a few months later to knock through the downstairs bathroom and put in a new suite. Again the same team did an excellent job and no task was too much for them to deal with. Rae and his team of confident builders were easy to work with from day one and were early on site and worked hard through out the day to complete the loft conversion and porch in 8 weeks, Which in our opinion was a very impressive turn around! They were clean and tidy every day and respectful of our neighbours. If we had to choose to do it all over again I would choose Rae. Thank you Rae and your team for improving our lifestyle beyond what we could have imagined :-)

Handyman- 17 Apr 2026
We couldn’t be happier with the amazing work Matt has done for us. What started with fitting a new bathroom sink and putting up some shelves quickly turned into several more projects because we were so impressed with his workmanship and reliability. He then installed a bathroom cabinet, sanded and restored our original floorboards beautifully, bringing them back to life and making them look brand new again. Matt also painted our entire house from top to bottom, and the finish is absolutely fantastic, we love how everything looks. On top of that, he put up mirrors for us and later installed a stunning Belfast sink in our kitchen along with a tiled backsplash, which has completely transformed the space. Matt is a lovely, polite, and incredibly hardworking and takes real pride in his work. Nothing was ever too much trouble, and every job was completed to a high standard. We are super happy with his services and would highly recommend him to anyone looking for someone trustworthy.

Bathroom Fitting- 6 Dec 2025
To answer your response :The original delay was due to a mix up on the company's part - the workman hitting his head came much later while work was being carried out on my bathroom. I was promised a start before last Christmas and instead work started in January, but that was nothing to do with an accident - it was an oversight on the company's part. Two different incidents have been mixed up and reported inaccurately. The blocked toilet should not have broken so quickly - I have now had to call plumbers out 4 times since it was installed due to it backing up. I never had this problem with my previous toilet. Two plumbers have now said it wasn't installed properly. Not only that, they had to rip off and break the tiles to get to the toilet because the tiles were glued too tightly around the toilet. To say that I should have been charged for your call out is laughable - I spent thousands on a substandard system which has broken down yet again this week and have spent hundreds since.

I am so glad that I have found Martin and his brother to complete my house refurbishment. Previous builders had walked off the job, Martin helped to finish plastering, changing windows, new roof, laid down laminate flooring, refurbish wooden balcony, and worked with building control in putting up the necessary metal support in place of the original garage wall. They are up front with everything, clear billing every fortnight. Cannot thank them enough.

Conversions - General- 21 Feb 2019
Steve was really friendly and made us feel confident that the job would be done well. The job was finished in one day as Steve had suggested, even with an unexpected situation arising during the job (a cable running straight through where we wanted the hole) he helped resolve it by finding the right person to fix the problem. We are so happy with the end result, it is exactly what we wanted and would recommend Steve.

Questions to ask local loft conversion companies in Newhaven

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 Newhaven?

A local loft conversion company in Newhaven 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 Newhaven 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 Newhaven 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 Newhaven

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 Newhaven before agreeing to start the work.

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

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