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.

Extensions- 9 Feb 2026
Firstly I would like to thank Scott and his team for their hard word completing our Porch build on schedule despite the cold and very wet weather throughout January. Scott is excellent at his job ( ground works and bricklaying ) and knows when he needs to bring in other trades to complete the project. Always on site when he said as with the other trades he booked. He kept me up to date throughout the build. We are very pleased with our new Porch and impressed with S.K Building Services work ethic and would highly recommend given them a chance to quote your building project. I will definitely use them again for any future projects at home or garden . Once again thanks Scott and team from a very happy customer - IAN & GINI -

Restoration & Refurbishment- 5 Sep 2020
Hubert and his team did an excellent job. We moved walls, relocated cloakroom, had a new kitchen installed, underfloor heating, megaflo and new flooring downstairs and everything that goes with it. They always showed up on time, neat and tidy and kept the overall timelines as agreed even though the refurb had to be managed during lockdown and we asked for additional works which they fitted in.

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

Will my home extension meet all building regulations and planning requirements?

Your Crowthorne 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 Crowthorne?

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

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 Crowthorne 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.
