Conversions - General- 13 Jun 2026
Tibi Construction transformed our home, and the standout areas were the open-plan living space, en-suite renovation, and extensive plastering work. The quality of the plastering throughout the house was exceptional, with perfectly smooth walls and ceilings that have completely modernised the property. The open-plan living area was a major project, and the team handled everything professionally, creating a fantastic space that has become the heart of our home. Their attention to detail and workmanship were outstanding from start to finish. They also completely stripped out and rebuilt our en-suite, installing a new top-fed shower, toilet, sink, and full tiling. The finish is superb and looks far more expensive than the cost of the project. What impressed me most was their honesty and transparency. Material costs were always clearly explained, there were no hidden charges, and communication was excellent throughout. The team were reliable, hardworking and overall outstanding

Bathroom Fitting- 19 Aug 2020
Mark gave me a price and a date for a bathroom refit. A week before the bathroom was due to be started Mark did not reply to any phone calls, messages or e-mails. Knowing that we were taking tiles off in preparation for the job, he never turned up. Mark has left us with no bathroom and no reason as to why the job could not be completed. Extremely unprofessional. Would definitely not recommended.

Plastering- 28 Apr 2021
Jay came to price the job after making contact and his communication was clear. We live in a very old house with lots of quirks; he took this into account and saved us a bit of money with the plastering. Plaster was falling off the ceiling and a couple of walls and he inspected the whole room, telling us we were fine to leave two of the walls as they were, as all seemed solid. I imagine he could have told us to have the whole room done, but instead we only had done what was needed. Jay managed to slot us in quickly, completing the work over two half days (allowing the pre-plaster adhesive coat to dry over night), finishing the job on a Saturday morning as a team of two. The price quoted was what we were charged. It's now been about a month since the work was completed, and we're very happy with the results. The room was skimmed nicely and the surface was very smooth. We coated it with Screwfix bare plaster paint before giving it a top coat, and the finish is great. We'll be using him again for future jobs and I have no problems recommending him.

Questions to ask local loft conversion companies in Berkeley

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 Berkeley?

A local loft conversion company in Berkeley 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 Berkeley 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 Berkeley 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 Berkeley

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 Berkeley before agreeing to start the work.

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

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