Bathroom Fitting- 9 Mar 2026
I highly recommend Brett at Sussex Oak Carpentry and would not hesitate to use them again. Communucation was excellent throughout and the job was finished on time and in budget and they were a pleasure to work with throughout - nothing was too much trouble. They completed 2 significant - and very different jobs - for us in an impressively short space of time. Firstly they refurbished our tired bathroom, installing new shower panels and LVT flooring over existing tiles as well as installing a new shower, door and tray and all new taps. It looks like a new bathroom. And then built a set of excellent shelves and wardrobe for a bedroom as well as replacing a door and restoring some damaged exterior woodwork. Excellent work.

Loft Conversion- 23 Feb 2023
I trusted Robert's advice on what was needed to be done for this project which started with a loft conversion and progressed to include a ground floor extension. Robert is a very considerate guy and very accommodating although not the most organised or tidy. The loft conversion work went well and I was very please with the result and with Robert's communication, however Robert had massively underquoted for the project and some of the workmanship was very poor and had to be redone (i.e.: tiling in the bathroom that resulted in leaks and damage to the ceiling in other rooms). As it transpires a lot of the issues we have now are due to a combination of poor workmanship (Robert's workmen are just not as skilled as Robert and we noticed that Robert was pretty much a 'one man band' and he spent a lot of his time also fixing what they were not doing right), poor choice of materials and that there were a lot of cutting corners. I am now left with a roof and dormer that have been leaking and causing massive internal damage to walls, ceilings, door frames, window frames and outdoor fascia that insurance will not cover due to poor workmanship and installation. Specialist roofers have identified multiple unfinished small jobs and incorrect use of materials that caused these issues. I have been unable to contact Robert via phone or email to discuss these matters.

The team at Palm replaced all of our timber weatherboarding with Cedral cladding (I found them via the Cedral website). Joey was amazing to deal with right from the start. He turned a quote around fast, it was clear and competitive. His team arrived when they said they would, they worked incredibly hard and to a very high standard. They were really easy and pleasant to have around the house too. Joey managed the whole process impeccably, right through to Building Regs completion, snagging and providing a guarantee. I didn't think it was possible to enjoy having building work done, but Joey and team proved me wrong!

Carpentry- 23 Nov 2020
Adam did a great job - very thorough in checking details beforehand, arrived on time, very polite and courteous. The job turned out to be more complex than expected but he solved the challenge and did a great job. Very considerate as well by minimising noise while we were working from home and ensuring our cat didn't get out either. Final result was expertly done. Very happy, highly recommended. Thank you!

Extensions- 6 May 2026
We have just had a front porch extension completed by Collier Homes, along with work on another room, and a new soakaway and driveway remodelling. We were kept informed at all times of how things were going, and (very importantly) if they were not going to be on site we were notified ahead of time - no mystery disappearances. The work took longer than expected, partly due to weather conditions and also due to further unexpected work being needed (e.g. the soakaway). At all times Ben and his team strove to excel and were obviously intent on doing the best job possible.

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.
