Extensions- 29 Nov 2023
We had the most fantastic experience with Sarunas. He was highly professional from start to finish and completed the work to the highest standard. We extended our project significantly once we realised how excellent he was and he has now renovated our whole home over an 18 month period. He was able to guide us through the process and help us make key decisions which made the experience smooth and efficient. He is extremely skilled in all aspects of building, has high attention to detail and is a pleasure to have in your home! I couldn't recommend him higher and look forward to having him back in future to convert our loft!

I have been in the carpentry game since the age of 12. Went to Richmond college to get my qualifications. I started on site for 4 years before going on my own. I have previously had a company on mybuilder doing flooring. Company was called L&Ds Flooring. Did this for about 3 years before having trouble with knees. Then went back to work with a family member doing extensions and refurbs and have been doing this ever since

Bathroom Fitting- 25 Sep 2018
Mustafa is excellent! He did a fantastic job on our bathroom - so much so, that when we decided on a more extensive construction project, he was our first call. He is communicative, friendly, and hardworking. All his team are sweet guys and they did a great job for a great price. I cannot recommend him enough.

Kitchen Fitting- 5 Nov 2020
An incredibly positive experience from start to finish. I found Robbie and team were hard workers, very likeable and provided brilliant results. Comms throughout were excellent. With Robbie happy to discuss the job over the phone beforehand and put our minds at ease. A big shout out to the team for undertaking this work during COVID. We understand the pressures this places on our tradespeople and we thank Robbie and his team for their diligence and commitment to wearing masks in our home and working safely.

Sean did a full refurbishment on our house. He is the most organised and customer friendly builder I have ever used. From start to finish there was a plan of action and then a great group of qualified tradesman to execute. Like every refurbishment, we asked for changes and he always made us feel like the extras were no problem. I have no hesitation in recommending CG Carpentry. They are now our go to builders and in our next move he will be the first person I call.

The job was to remove a stud wall with an archway between my kitchen and hall. Pawel was excellent from start to finish. He was good to communicate with before, and answered my questions fully. He turned up on time, was very neat and kept the noise down. He did a great job and cleaned up afterwards. I’d recommend!
