Extensions- 15 Dec 2022
Recently had an extension undertaken by C&C. I put the feelers out for contractors and they were fast in quoting and managed to squeeze me. I'd had massive issues with my previous contractor so I was a bit wary at 1st but the lads were spot on. Kept in constant contact, updated me on any issues, worked with me on any changes that needed to be made and did what they said they would, at a very fair price. The lads took ownership of contacting building control, grabbing materials where required and also drafted in additional help or trades when needed. Even after completion the lads have said they will come back and do any snags required if I spot anything. Can't recommend them enough.

Hybrid Builders
Rating: 5 out of 5
Extension Builder in Bolton, North West England
Hi, I’m Darren - a skilled builder with over 20 years of hands-on experience, currently serving the Wigan area and beyond. I’ve worked on a wide range of projects and have a strong grasp of all aspects of building work, including electrics, plumbing, joinery, plastering and structural alterations. Whatever the job, there’s a good chance I can get it done. I’m known for being reliable, approachable, and easy to work with (and I brew a mean cup of tea too). When I’m not on the tools, you’ll likely find me out kayaking or riding the waves on my jet ski. If you have a project in mind or simply a few questions, don’t hesitate to reach out - I’m always happy to chat. Looking forward to hearing from you, Darren

Groundwork & Foundations- 26 Jun 2017
Rob and his team are by far the best tradesmen I have ever worked with. They listened to my ideas and brought their experience to bear on the project. Their estimates were competitive and accurate and their work ethic was fantastic. They even managed to save me a bit of money with their innovative thinking and product suggestions. I probably wasn't the easiest client to deal with... last minute changes etc... but the team were extremely accommodating and understanding. I highly recommend Groundworks & Civils for any kind of similar work you are thinking of undertaking. The test of a good tradesmen is whether of not you would use them again. I will and I did. Thanks for doing such a fantastic job, Rob! On a personal level, they are a great set of guys too. What more could you want :-)
