Extensions- 17 Aug 2024
Amazing 5* work! Highly recommend James and team. We had a kitchen ground floor extension completed last year; it has exceeded our expectations. James followed up all issues and questions in a professional manner. Jimmy fitted the flooring throughout the ground floor - perfect. Despite the appalling weather the work was completed on time. The extension is also built to such a high standard it weathered the Stalybridge tornado in December!!! Photos to follow 😊 we can’t thank you enough James!

Conversions - General- 5 Feb 2025
Carl discussed our requirements, offered suggestions and provided 3D plans. The quote was very competitive and even included a small utility room which we didn’t expect. Throughout the conversion Carl explained each stage of the process and everyone involved was polite and friendly. The work was carried out to a high standard and this has been commented on by others. We are delighted with our beautiful new kitchen diner. Thank you Carl and the team.

Extensions- 11 Apr 2023
Daniel and his team came in to complete an extension which was originally started by other builders. There were many issues left by the first builders but, Daniel tackled each one in a professional manner. I would highly recommend Valery Home Decor Ltd. If you are like me, after being badly let down by previous builders, I found it hard to trust anyone but, I found Daniel to be completely trustworthy, hard working, and stood by his word. He won't let you down!

Extensions- 16 May 2020
I've just had an extension built by Smiths Building Services. They are prompt, professional and very knowledgeable . The quality of work is excellent and very precise. Their knowledge enabled them to recommend alterations to the original plans, which not only made the project cheaper but also made the building stronger. Also despite difficulties outside of their control kept the price as close as possible to the original quote. I would definitely recommend them for your building needs.

Carpentry- 10 Aug 2026
Luke and his partner were really lovely and on time / great with communication. However the work completed really isn’t up to scratch. The stairs are all uneven, the door made doesn’t close and there are obvious nails pointing out of the unit. This is a little more worrying since this is for our babies room. Sadly we’re too late to feedback as we’ve not been in the house for weeks.

An extension builder in Oldham 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 Oldham 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 Oldham?

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