Conversions - General- 29 Sep 2022
The job - gutting our living room. Tearing down the ceiling, removing all old wallpaper and ripping up the floor in order to insulate and add lighting. While we were doing this, we decided to replace the main steel in the living room (which was oversize and impacted the floor height in the guest room) and do remedial works in the guest room. The steel replacement was not time budgeted, but Oli and Tony didn’t hesitate to quote,To make time for us and bring in the structural engineer. Probably added 3 weeks to their time on site. The trades they brought in (plumbing for heating, electrician for downlighters, structural engineer and plasterers) were all professional, did an excellent job and were all unfailingly polite. It was easy to build a good, positive relationship with them, to the point we felt comfortable giving them the keys to the house so they could work while we went away for two weeks. They sent photos of their progress and showed up and worked as if we were there. I was very impressed by the state of the house when we got back. They watered our plants (I didn’t ask) and they cleaned the hallway so that it was spotless. They did a good job for a fair price, and were always cheerful and open to conversation. They came back to do a few snagging items without being chased (this is a huge thing for me, after having chased many builders to finish bits and pieces). I would definitely use them again.

Loft Conversion- 1 Mar 2026
We can’t recommend Gary highly enough! A couple of years ago, he transformed our old granny-style bungalow into our dream home. He managed the project, removing the roof, adding a second floor, and gutting the ground floor/adjusting the layout with impeccable craftsmanship. Every detail was carefully considered, from electrics to tiling to high-quality cladding. Gary kept everything on budget, and had clever ways of helping us to save money, for which we could spend elsewhere. He also had great advice for adjusting certain elements of the build which we decided to implement. Communication was great, and we loved Gary’s brother Jon who worked day and night on the project and was lovely to be around with a great sense of humour. Gary and his team were not just skilled, but genuinely lovely to work with. We’re blown away by the final result, and we’ll definitely be calling him for future projects. Thank you Gary, Jon and team!

Loft Conversion- 10 Jan 2023
The title “Above garage finishing” rather undersells the project. Coleman Construction installed a bathroom, gym/bedroom in a room above a double garage. This included creating a room with storage cupboards, insulation, plastering, painting and electrics. The standard of workmanship from the whole team was excellent. They started early each day and worked hard and efficiently. All of the team were friendly, helpful and careful throughout. If I was assessing Coleman Construction out of 1 to 10, with 10 being outstanding, I would award a 10. I can throughly recommend their workmanship and would be happy to show you the finished job if asked to do so by Coleman Construction. This is a company that cares about delivering a high quality product and who delivers what they said they would do.

Dennis gave a good quote, answered any questions I had, was understanding when the door was delivered damaged and had to put the job back a week. He arrived on time, he was clean and tidy in his work and made easy work of fitting our wheelchair access bathroom door (3ft wide). We are very happy with the finished result and will definitely go back to him if we need a carpenter in the future.

Questions to ask local loft conversion companies in Liss

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 Liss?

A local loft conversion company in Liss 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 Liss 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 Liss 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 Liss

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 Liss before agreeing to start the work.

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

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