Kitchen Fitting- 31 Jul 2019
Can't recommend this guy enough! Pat is a professional from start to finish. He came to quote me for a complete kitchen refit, within a few days he had emailed me a detailed quote and we agreed a date. My kitchen came with many unforeseen problems and challenges but Pat rose to them all. Aside from being a skilled carpenter and a skilled builder he is a great problem solver. He is reliable,trustworthy and very approachable. When I was getting stressed out he would calm me down and reassure me that everything would be ok. Sounds silly but my kitchen issues would have stressed a saint out! To summarise, my kitchen has turned out beautiful! Pat has done the work to a very high spec and gave it the wow factor! I absolutely love my new kitchen and am so happy that I chose Pat to come and do it for me. Look no further!!! Hope he posts my before and after pics on here and you can see for yourselves!

Extensions- 29 Apr 2026
Heera, Jagthar and team was my first personal experience with builders. Let me tell you, it was a pleasure to have them do our porch and other renovations in the house. They are so courteous, hard working and provided a great service. Firstly, I had a comprehensively written quote breaking down all of the steps required. Heera then ensured to keep me in the loop of any developments/any changes of plan required, outlining the reasons why and options, making it easy to understand and work together to completion. Their finish was to a high quality and they would always go the extra step to ensure this. I highly recommend AS Builders for any job and will definitely use them again in the future, and would recommend to my friends and family also. If you are considering them, grab a free quote and go from there... That's what I did! Thank you AS Builders for our renovations!

What to ask a Ashtead extension builder before hiring?

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

An extension builder in Ashtead 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 Ashtead 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 Ashtead?

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 Ashtead 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 Ashtead 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.
