Carpentry- 15 Aug 2025
I would 100% recommend John and his team. We have been really unlucky with 3 other builders taking off with our money and not completing the work. John is very professional, took on someone else’s mess and done a brilliant job. We wanted exposed oak rafter detail and the team done an excellent job. John is very good at problem solving on the spot when there are issues, he is very approachable and keeps you updated with the progress throughout the job. What he has been good at is also talking through different options with us before doing different sections of the work and he does not take short cuts. If you need excellent honest builders John is your guy! We will get the decorations done and post the end product.

We honestly can’t thank the team enough for everything they’ve done. From the very first day to the final handover, they have been incredibly professional, knowledgeable, helpful and so patient. They always took the time to answer our questions, offer advice and make sure we were completely happy every step of the way. Building work can be stressful and unexpected challenges are inevitable, but every obstacle was met with a smile and a solution. No problem was ever too big or too small, and nothing ever seemed like too much trouble. Their experience and attention to detail gave us complete confidence throughout the project. The quality of the workmanship is outstanding, and it’s clear they take enormous pride in what they do. They treated our home with respect, kept us informed throughout, and genuinely cared about delivering the very best result rather than simply finishing the job. They haven’t just built an extension and renovated our home—they’ve created a space that our family will enjoy for many years to come. We are absolutely delighted with the finished result, and it has exceeded everything we hoped for. If you’re looking for builders who are trustworthy, reliable, highly skilled and genuinely care about their customers, we couldn’t recommend them more highly. Thank you for making our dream home a reality.

Landscaping- 17 Mar 2024
Very pleased with the work undertaken by Centurion Building Services. Mark and Neil were very professional and courteous. They arrived early each morning and worked in very bad weather to get the job completed. Ben was on hand to oversee the job and to complete the pointing. We could not have asked for a better team of builders. They cleaned up after every days work and left everything neat and tidy. These guys are the best!! I would certainly recommend them and they are now my 'go to' builders. Thank you Grant, Ben, Mark and Neil for a superb job that has certainly enhanced the kerb appeal to our house.

Questions to ask local loft conversion companies in Redhill

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 Redhill?

A local loft conversion company in Redhill 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 Redhill 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 Redhill 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 Redhill

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 Redhill before agreeing to start the work.

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

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