Bricklaying- 20 Dec 2016
Ashley & his team did a outstanding job doing our porch. After we got let down by another contractor in the summer & was about to give up on doing the works this year. Found Ashley on my builder, it was the best thing that happened, he managed to turn it around & get it all done before Christmas for us. Excellent work from start to finishing. Prompt & reliable. Would definitely recommend Halsey construction.

Loft Conversion- 23 Jun 2024
Singh builders was contracted to do the shell of my loft conversion. It was a daunting task at first choosing the right contractors but Singhs builders were reassuring right from the start as well as knowledgeable and reasonably priced. They have gone above and beyond to meet my needs and ensure I was pleased with everything every step of the way. The quality of their work is to an extremely high standard. To say I am pleased is an understatement! I would definitely recommend again!

Handyman- 11 Feb 2025
Brady & Cesar did an excellent job hanging/painting six internal doors. The door frames weren’t straight, which made the job more challenging, but they took the time to get everything just right. They were meticulous in their work, covering the floor to protect our home and ensuring everything was clean afterward. Both explained what they were doing throughout the process and provided a personable, professional service. Would highly recommend Davis-Brady Construction Limited

I am a carpenter and roofing specialist with over 20 Years experience, over the last 15 years I grew a construction company with many employees and many happy customers, but found at times that this format lost the personal touch with the client. I recently decided to bring the business to a close and start again doing the smaller projects with direct contact which each customer, to enable me to provide a consistent and tailored service to each customer with client satisfaction being the main priority. I specialise in loft conversions, small extensions, all aspects of carpentry, garden buildings, decking, roofing, insulation, tacking and project management. I also have a large contact list of all trades so can manage all parts of any project, however I generally look for projects with enough works suitable for me to complete personally so I can be present and working on the project from start to finish.

Extensions- 14 Jul 2021
Juro and his team completed a total refurbishment of our house that included removing all internal walls, along with a double story side extension, a huge job involving lots of steels, re-roofing, new construction, new bathrooms and kitchen, new windows and rendering along with all the plumbing and electrical work and decoration. They did the most incredible job, working efficiently, adapting to any problems that came along and working really hard to create the best finish possible at the budget we had. Despite the pandemic arriving just after the demolition stage, they didn’t miss a day on site, and worked tirelessly to get materials to keep the project moving. Incredibly they still managed to finish the project on schedule and to a standard that was exceptional. Juro is honest and upfront, didn’t ever add costs or ‘unforeseeables’ and was an absolute joy to work with. He also stuck to a very clear payment schedule that was easy to follow and always meant we only paid when we were absolutely 100% happy. My only reservation in writing this review is that I would like to selfishly hang on to him and keep his schedule clear for future jobs with family and friends!

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

An extension builder in Betchworth 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.

What experience do you have with similar extensions in Betchworth?

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