Carpentry- 29 Apr 2018
The whole experience with Toby was fantastic. He was professional when he arrived for the quote and the way he advised us on a solution. The reason why I selected T.Wood Carpentry wasn't just their presentation when we met, but they way he conducted himself prior. Booking an appointment along with text/email reminders, also the way the quote was sent to us. It wasn't just a standard email it will cost x,y,z. It was a business email response along with an attached professional looking quote detailing the work to be done - as well as the cost of options of splitting the job if we wanted to. The cost also included a breakdown of labour and material charges. On the day, Toby and his team arrived promptly at 8am and worked solidly until 3pm! You can't fault how hard Toby works! One thing that stood out to me was also good use of H&S when floorboards were being cut outside, so many times you see tradesman cutting corners! When the job was complete, they tidied up and hovered (even the stairs carpet which was being taken up that afternoon!) The workman ship was fantastic, honestly I will not hesitate in using Toby again for my carpentry needs. It was reassuring that Toby said, if there were any problems he would come back round - even though he said there shouldn't be any now! The invoice arrived promptly, and again this was professional. It was clearly broken down, along with clear proof of purchase for additional insulation! Thank you Toby for sorting the squeaky floorboards out!

We chose Lee to carry out our dormer loft conversion shell build. Lee met with me first to go over the project, discuss timescales and shortly after provided a quote. Lee and his team completed all the work on time and on budget. In fact, they finished ahead of schedule. Lee had excellent communication throughout and was always available to talk to, which I really appreciated. Would happily recommend Lee :)

Fencing- 12 Jun 2020
From the time we engaged H&SCL until the completion of the job, we found Tommy very affable, and professional. We appreciated him coming to survey the job before commencement, and although we made a few adjustments to our original request, it was accommodated and priced within our budget. Our garden is more secure and aesthetically looks better thanks to our new fence panels. Tommy's 'above and beyond' mannerism ensured the job was completed to our expectations. Will definitely be requiring his services for the next phase of our little garden project. Tone & Claud

Questions to ask local loft conversion companies in East Sussex

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 East Sussex?

A local loft conversion company in East Sussex 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 East Sussex 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 East Sussex 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.
