I hired Paul to do the refurbishment work of my property in early 2023 and paid the deposit as requested. He asked for money to buy material for the kitchen in Jul 2023. I paid and informed him my choice of items as requested. The work then stopped. He has not returned the money to me until now.

Extensions- 27 Apr 2026
We enquired about a front porch installation and were impressed to receive a prompt response from Ascension Property Developments & Construction. From the outset, they were responsive, professional and easy to communicate with. After scheduling a call, they took the time to clearly and thoroughly explain the entire process, answering all of our questions and ensuring we felt confident moving forward. They were also very accommodating with scheduling, arranging for the work to begin while we were on annual leave, which made things incredibly convenient for us. Once the project started, the team worked efficiently and kept us informed every step of the way. They even set up a group chat to provide daily updates and create a space where we could easily ask questions or raise any concerns. This level of communication made a big difference and gave us real peace of mind throughout the entire process. The end result is fantastic and our new porch looks beautiful!

We recently had the pleasure of working with Lakshmi Vilas Ltd, and we couldn’t be happier with the results! They undertook a major project for us in Reading, which included extending our house with bathroom, renovating the entire interior, and paving tiles in our backyard. Every aspect of their work was carried out with professionalism, attention to detail, and exceptional craftsmanship. The house extension was seamlessly integrated with the existing structure, and the renovations transformed our home into a modern, comfortable, and beautiful space. The team was punctual, respectful, and kept us updated throughout the process, ensuring that everything was completed on to a high standard.

Extensions- 14 Nov 2023
Russell and his team have been brilliant throughout. You take a punt when hiring a builder and we couldn’t have chosen better. From the initial meeting right the way through he was communicative and very clear with regards spend and schedule. He was very conscientious about being tidy which, given building an extension is a messy process, says a lot. We had a single story side extension and the whole process from start to finish was very speedy. We never felt like there was a lull in progress and things always seemed to be moving in the right direction. I would highly recommend Russell and his team if you’re looking at having an extension. I don’t have a negative comment to make. All positive. 👍

Gas Work- 27 Nov 2013
I thoroughly recommend Mr Tim Friedenheim. He is multi-skilled, prompt and reliable. He demolished a very large stone fireplace, rebuilt the hearth and chimney surround, made good the walls, installed a new gas fire and gas run, and carried out associated electrical work. All this was done quickly and efficiently. He is also an extremely clean worker and carried out a big and potentially very messy job with the absolute minimum of disruption. An excellent all round, reliable and many-skilled tradesman. Highly recommended. 27 November 2013

Bricklaying- 31 Oct 2019
Nic, did a super job. The finish detailing of the brick wall connections look great. He went above and beyond in regard to making sure he did what I wanted, each step of the way, and didn’t assume anything. He tidied up afterwards, helped with getting materials sorted, offered to drive unused materials back to the builders yard for me, turned up on time, and was pleasant and friendly to have around. I would highly recommend him to anyone.

Hard Flooring- 30 Nov 2024
Very disappointed,they are not answering my calls anymore.At the first time I was happy-the builders seems polite and professional .After they left I realised that the work wasn't done properly i noticed bumps all over the floor,making look terrible.when.They had to comeback and finish the job that I already paid them for the silicone around the edges.when they returned they just completed the half the work and they told me they will finish the kitchen after.When I pointed out the bumps everywhere they claimed because they had walked on it.But after checking the bumps are everywhere on the floor and the issue was uneven subfloor.They had told me they were trying to flatten the surface before installing the floor and they just added more glue instead of properly levelling it,as professionals they should have fixed this before laying the LVT. Now I’am left with a poorly finished floor.Very disappointed,frustrated.Would not recommend unless they fix their work .

Your Berkshire 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 Berkshire?

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