Extensions- 26 Jun 2018
Andy and his team came to build my single story extension. Could not recommend him highly enough for his high quality work and finished product. Finished all the work to the time scale he told me and turned up everyday from start to finish. Always communicated with me to understand what was going on with each stage and went above and beyond to help me. Very clean and tidy. I still have lots of work to do with a garage conversion for one, and will not hesitate to use Andy again. Brilliant. 10/10

Extensions- 30 Jan 2020
We cannot thank Danny and Constructek enough for our beautiful extension. From his first visit to look at the project and quote through to the last this week to complete Danny and his team have been amazing. All of the trades people were so friendly and accommodating. Danny handled all of the tradespeople and deliveries for us, making the whole process such a job. The standard of his work is beyond exceptional and it is clear why he is a Master Builder. Nothing is too much trouble and Danny accommodated our every request. He and his team made our project a joy to have built. We really cannot recommend his company enough. We would be more than happy for any of his potential customers to come to our home and see the exceptional work they have done. We are over the moon with our finished project and will be using Danny and Constructek again. Thank you so very much more making our dream a reality.

Plastering- 4 Aug 2021
Nick decorated the outside of our house including some rendering around the windows that had been left unfinished by the previous builder. I explained to Nick I have very high standards and the work must be very neat.He assured me it would and he didn’t let me down. Plenty of communication before the job due to bad weather the job was delisted and throughout the job he kept me updated. Extremely pleased with the result and would be happy to recommend Nick to anyone. A pleasant and trustworthy guy, who I will use again.

Had wood delivered. Did not turn up to start the job. I tried calling and it sounded like he was asleep. Would not take any further calls. I asked for wood to be collected as he is unreliable but it is still here.

What to ask a Guildford extension builder before hiring?

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

An extension builder in Guildford 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 Guildford 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 Guildford?

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 Guildford 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 Guildford 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.
