Restoration & Refurbishment- 2 Apr 2026
Really pleased I chose Leigh Matthews for this job. We were taking over a building that was unoccupied for 18 months and there were some issues with that, The team were excellent, and they finished the 4-week job on time, and right on budget. They were helpful and considerate and left the premises clean and tidy. They were also able to help out with some problems with the plumbing that were not in the original scope. I loved the way they did the estimate and the invoicing. Breaking all the items down into the individual tasks and at the end of each week, itemising which tasks were complete and a %age on those in progress. I would not hesitate to employ them again

Extensions- 27 Jun 2022
Very very happy with Michael's work. From the day one of the meet till end of the project, he and his team been quite professional and have been working with high standards. We received range of quotes from different builders and Michael's quote was somewhere in middle with good quality of work which we have seen during our site visit for his other projects. So, decided to go with him. One really good thing you get from Michael is plenty of ideas and options. From our original drawings, he suggested some changes which were really useful. Being a lay people, During the project we were confused in some design options and Michael really assisted with 3 to 4 options and he suggests which one is the best from his view point but also been flexible if we wanted to do in specific way. He was daily coming to the site to monitor quality and progress of the work. All his team is highly skilled and experienced. The all do general building but when it comes to specific, they have specific tiles, electrician, plumber, painter etc etc who finishes the job at very high quality. They work flexible to complete the job on time and keep the area safe and tidy. In terms of managing project in budget, we had a good experience where Michael will in detail explain what is covered in agreed amount and where the extra cost will incur if there are major changes. I am taking this much time to write this review so that it can help others to see my good experience with Michael. 100% best.

Extensions- 15 Jul 2019
Norbert and his team have transformed our house to the most amazing standard, we would recommend them to all our friends and family. The work schedule was managed so well, with minimal disruption to us with two young boys. We had a loft conversion, main bathroom renovation, utility room, downstairs toilet and a 4 meter kitchen extension. We stayed in the house whilst the work was being completed and Norbert and his team fitted in so well, it actually feels weird not seeing them in the house. They are such a lovely bunch of people. We are over the moon… on time, on budget and finished to a high standard. If we ever undertake renovation work again, Norbert and his team would be our 1st call!

Restoration & Refurbishment- 17 Jul 2016
Valter was very impressive on his initial visit with some exciting ideas for the house improvements and we had no hesitation in choosing Happy Building above the other two building firms who quoted. Having signed off on the budget and scope of work, Valter's team of builders arrived. We were hugely impressed with the skill, experience and work ethic of the team; the fact that they arrived early each morning smiling underlined the "Happy Building" epithet; Jarek, the site foreman, had an especially cheery demeanour. The work involved stripping the walls back to bricks, removing walls, reinforcing foundations, plastering, extending the bathroom and removing one bedroom to create a large ensuite bedroom. The latter certainly would not have been done without Valter's vision and patience in explaining how it would look. We were able to deviate from the original plans without any problem which was very important in achieving the final look which we had desired. Valter was very careful in sticking to time and budgets which I had never experienced before with builders. The kitchen, bathroom, two bedrooms, living room and hallways were finished to the highest possible specification within our budget. There were one or two small features which, with hindsight, we would have improved such as door handles and shower fittings, however this was down to us not specifying exactly what we wanted. These are very minor details and a tiny part of the overall picture.

Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

In fact the old cracked rendering was completely removed and a new base rendering applied. The cracks could have been patched but the problem would have come back. So not the cheapest solution but the work was very professional and to a high standard.

Questions to ask local loft conversion companies in Leatherhead

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 Leatherhead?

A local loft conversion company in Leatherhead 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 Leatherhead 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 Leatherhead 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 Leatherhead

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 Leatherhead before agreeing to start the work.

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

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