Conversions - General- 26 May 2010
Thanks to Lester and Chris, all work completed, very easy to work with and any questions/queries we had were always addressed. Left the place tidy each time and kept us informed of what was happening. Last few little bits tidied up and any problems have been told to get in touch with them. Out of four builders contacted on here only Lester turned up to quote and once his quote was approved he rang to organise start date, they were here every morning at 8am without fail. Really pleased with end result, thank you.

Extensions- 12 Jan 2023
Philip, Chris and Ollie were a pleasure to have working on our house. They were very efficient and answered all questions with ease and great explanation. I cannot fault their work as even though it was an easy looking extension, it actually had a few issues. Philip’s quote was perfectly broke down and detailed. This was 1 of the deciding factors for us because of the detail in the quote. All 3 were also brilliant with my kiddos and my dog (who kept getting let out). I am very happy with the work that has been done, it has created a beautiful space that makes a huge difference to the house. We cannot wait to have them back to do our back extension.

P r tiling ltd
Rating: 5 out of 5
Extension Builder in Malmesbury
Hello everyone, Firstly my name is Paul Rozycki. For the last 20 years I’ve been involved in many aspects of tiling, carpentry and wet room/bathroom installations across Wiltshire and throughout the Cotswolds. I have been fortunate enough to have never needed to advertise throughout this period. The last 10 years I have been solely focused on what I referred to as my bread and butter working at The Lakes by Yoo in Lechlade. Unfortunately this work has sadly come to an end and so have decided to change direction in my approach to acquiring work. If I were to describe myself I would say I’m a specialist in wetroom installations, standard tiling and specialist tiling, including large format, all types of stone etc I have many years experience in general carpentry as well as plumbing and general building works. I’m very approachable, offering my clients my knowledge and expertise to achieve their visions to the highest of standards. I’m more than happy to provide images of my previous projects and references from my clients, as well as offering a free visit and quotation for any potential works.

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

An extension builder in Malmesbury 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.

Will my home extension meet all building regulations and planning requirements?

Your Malmesbury 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 Malmesbury?

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