Kitchen Fitting- 29 May 2020
From initial contact to completion of the job, Sawyers Kitchens were thorough, efficient and professional. Tommy and Jake are good, honest, highly skilled tradesmen who were a pleasure to work with. This job involved fitting a new kitchen from scratch and the guys did it with ease. Even additional jobs that were required along the way were no hassle or issue for them. I couldn't be happier with the work carried and would highly recommend Sawyers Kitchens. 10/10.

Painting & Decorating- 29 Apr 2025
Nathan, Daisy, and Dan renovated and redecorated the front of my neglected Edwardian detatched house. Nathan replied to all my posts on Mybuilder.com immediately. He visited the property at the agreed time, and gave a thorough and detailed analysis of extra problems I had not forseen. He emailed a very reasonable quote the same day. The team started work within a week after I accepted the quote. They worked unobtrusively, doing a thorough job, explaining at the end of each day what had been done, and explaining the next stage. I would recommend them.

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.

What to ask a Havant extension builder before hiring?

Before hiring an extension builder in Havant or extension building company in Havant, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

What qualifications and experience do you have as an extension builder in Havant?

An extension builder in Havant should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Havant extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Havant?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Havant extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Havant extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
