Extensions- 20 Feb 2020
Decent builders but with extremely poor communication skills. First the good points: 1. They are good at internal finishes 2. They create and use a Statement of Work (SOW) to track all costs of the project, so there were no major surprises in the project 3. They are friendly and hard workers - who arrive on time Gotbath UK Ltd used subcontractors to build us a 6 meter rear extension. Although they had an in-house architect, they did not know the law around boundaries which resulted in a conflict with our neighbours. After spending hundreds on hiring a boundary surveyor, the initial wall had to be re-built within our boundary. Gotbath did not take any responsibility for the wrong information they provided to us regarding boundaries and charged us for the rebuild. When discussing how to finish the inside of the extension, GotBath were extremely slow in ordering supplies and in general responding to us, so we took matters into our own hands and ordered materials ourselves which were removed from the SOW provided to us. At the end of the project, finishes took a long time and required constant chasing. Final gas, electrical and warranty documents took a long time to reach us and required a lot of chasing too. I have very little confidence that GotBath will honour the warranty document they have provided to us. It's a shame because I can see GotBath have a lot of potential as a builder. However, their lack of communication has really let them down.

Extensions- 13 Nov 2020
Avoid these traders. They are amateurs and have caused me no end of pain with a small single storey front extension. I sacked them in the end as we just could tale anymore of their slap dash approach.

Conversions - General- 6 Feb 2023
Sorry this is long: our experience differs to most on here. We chose Better Living to do our side and rear extensions from start to finish. All was good until the subcontractors finished the main structures, then it all went downhill. Ben rarely answered his phone, texts, emails etc., and because they had started a bigger project elsewhere they repeatedly abandoned ours, often for weeks at a time. Even when we went on holiday, they had the complete run of the house for two weeks but did very little. Ben deliberately held up work for two weeks after receiving a stage payment a day late, having given us one day to pay after emailing an invoice. Beyond the main structural jobs their work was often sub-standard and our instructions were not followed due to poor communication between the team. Out of frustration we eventually took a lot of work off them and drafted in other tradesmen to complete the project, also doing some of the work ourselves. We have since had to have some of their heating work rectified by engineers. Not saying everything was bad, but fact is the list of problems and poorly completed jobs is too long to list here. They finished at our property over three months ago and have still not sent us the completion documents. As usual, Ben is not responding to our attempts to contact him. Despite being hospitable to their team, we feel we were treated shabbily by BL and sadly would not recommend them.

The project lasted from July 2023 to Feb 2024 and comprised of: 1. Single story rear extension with new kitchen and underfloor heating 2. 75m2 patio 3. Internal reconfiguration including removal / installation of walls, new flooring, plumbing (including new boiler), new door frames, doors and skirting, redecoration, carpentry for cupboards 4. Ventilation of existing roof The team are both friendly and professional with Alin always on hand to manage any questions / situations as they arise. The work is clearly costed and every two weeks a valuation takes place to ensure transparency of work undertaken both in original scope and any extras. The quality of the build was excellent, something the building inspector commented on. Alin was recommended to me based on past work, and I in turn would highly recommend him.

What to ask a Windlesham extension builder before hiring?

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

An extension builder in Windlesham 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 Windlesham 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 Windlesham?

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

Do you offer a guarantee for your work? Most Windlesham 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.
