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 qualifications and experience do you have as an extension builder in East Cowes?

An extension builder in East Cowes 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?

What experience do you have with similar extensions in East Cowes?

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 East Cowes extension builder’s ability to deliver a result that meets your expectations.
