Loft Conversion- 21 Sep 2024
First of all, Manuel, Mike and the team are life savers. They took on our small but rather complex loft conversion after we were badly let down by the previous builders. The job involved the replacement of the whole roof structure including the installation of steel beams, adding Velux roof lights, an ensuite bathroom, electrics, plumbing, skimming and decorating plus installing a whole new staircase. Despite various challenges the team stayed positive throughout and always managed to find a solution. We did have limited space and lived and worked onsite alongside the works which was not an easy undertaking. Manuel and his team managed to get the job completed to our satisfaction and we are very happy with the results. Naturally, with a complex project like this there is always room for improvement in terms of planning and communication and working efficiently with the various trades. Ultimately, if you're looking for reliable and outcome-focused builders we can only recommend MMMB.

Restoration & Refurbishment- 25 Feb 2026
The job was going good then we had an issue with a leaking soil pipe which had rotted the floor boards and a joist Dave and his team then removed the floor boards and then the found another 2 leaks coming from old pipework. Dave and his team then found that the wall was sitting on the rotten floorboards. After taking a look at the situation Dave came up with the idea to build a frame under the wall to support it. This was quickly done at a reasonable cost the rest of his work was done to an excellent standard any issues we had Dave and his team sorted them out, the work overran by a few days due to plaster taking longer than expected to dry out. Very pleased with Dave's work, nothing was a problem that couldn't be solved . I would recommend Dave and his team

Loft Conversion- 18 Mar 2019
From the first visit to the completion of the work, Greg was first rate! We had a number of companies quote for the job but Greg was the only one who seemed honest about what was needed and his pricing was very competitive. He turned up on time and finished the job within the agreed budget and timescale. The work is to an incredibly high standard. Not only that but he and his team fixed a number of bodged jobs from previous work on the property. Friendly, hardworking, polite and professional... I would not hesitate to hire him for future work.

Plastering- 23 Nov 2016
Bill quoted for the rendering job but I also had him quote for some internal plastering. He has completed the plastering with the rendering on hold for now. I would highly recommend Bill who provided a detailed quote and when asked to do a bit more kept me informed of the additional costs. He was reliable as in turning up when arranged and worked hard. Having used Plasterer's before I can say Bill was the tidiest I have experienced and obviously respectful of working in someone else's home. His work was to a high standard and I got the impression that he wouldn't be happy if a job wasn't done right. I would recommend Bill for your plastering needs.

Questions to ask local loft conversion companies in Winchester

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 Winchester?

A local loft conversion company in Winchester 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 Winchester 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 Winchester 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 Winchester

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 Winchester before agreeing to start the work.

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

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