Extensions- 6 Jan 2023
I am doing a double storey L shaped extension and the experience has been great so far. Vascontractors have been open, transparent, clear in communication. Have always understood the customer need. The quality of workmanship seen so far has been great be it building work, tiling, joinery or painting. Always provided a detailed timeline and schedule about the work. They even put extra hours and days for us to move back home. Everyday after work they tidy up. Even neighbours have given good feedback that they are unlike other builders who make lot of noise. Those minor things really matter when it comes to big jobs. They are fully committed to the job. I would highly recommend Vascontractors to anyone looking for big/small builds and making it a joyful experience for them.

Joinery & Cabinet Making- 7 Feb 2019
I had three quotes and Chris was the most competitive for the job. He was able to come and assess the job soon after making contact and provided a quote quickly afterwards. He was accommodating on timescales and on the day he and Dylan turned up bang on time and got to work quickly. He took care with mess and cleaned up well after the job. Chris consulted with me on little design decisions that needed to be made on the day and the end result is a very good job boxing in my Ikea bookcases that I just need to paint (I hadn’t asked him to do this for me). I’ve got the result I wanted for a fraction of the price of custom built cabinets. Chris is a super friendly guy who was happy to advise me on some questions I had about possible works in my home. We have two nosy dogs who love to acquaint themselves with whomever comes to the house and he and Dylan were great with them. I’d definitely hire him again.

Latest review:
We have contracted H&J Properties for our house refurbishment in London. I was impressed with the team's professionalism and project management from start to finish. We had no plans or planning approved, so we wanted a design and build company who will be able to look after the project from start to finish. They did just that. Working with the architects and the planning application before starting the project planning. As always, there are, of course, unforeseen issues arising with the old houses in london but I could't be happier with the communication received from the team. Thanks for the great job.

Latest review:
After a previous contractor took our money and left our loft extension unfinished, we were devastated and worried about how we would ever get our home back to normal. Then Lewis from Lebelle stepped in and completely turned things around. Lewis was patient, understanding, and incredibly professional. He worked quickly, kept costs under control, and finished the loft extension to a standard we’re so happy with. The stress he took off our shoulders was unbelievable. We honestly can’t thank Lewis enough. If you’re looking for someone trustworthy, skilled, and genuinely caring, Lebelle is the company to call.
