Undertook extensive building work - a rear and side extension, built a summer house, landscaped the garden and paved a new driveway. They are the best building company I have ever worked with. Courteous, tidy, excellent quality, considerate of our family and our neighbours. Afrim consistently gone went and beyond to ensure that my renovations were completed to a high standard and at a fast pace. I am so pleased I made the decision to let him manage the building work from start to finish as his electrician, plumber, tilers, kitchen fitters have all been fantastic. Building works can be extremely stressful but Afrim did everything to make sure it has been as smooth as possible - would highly recommend

Extensions- 13 Jan 2019
George was excellent throughout - would highly recommend. Although I did not hire George to complete the whole job (as someone in my family is a bricklayer) he was instrumental in completing the build. A few points to demonstrate: - Fair and transparent quote (which was stuck to); - Flexible throughout delays caused by me (planning, etc.); - Supportive (advice on what he would do if he was running whole job); - Professional (including team). I will use him again.

What to ask a Redhill extension builder before hiring?

Before hiring an extension builder in Redhill or extension building company in Redhill, 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 Redhill?

An extension builder in Redhill 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 Redhill 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 Redhill?

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 Redhill 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 Redhill 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.
