Landscaping- 30 Mar 2024
Chris did a phenomenal job with our garden transformation. From the very beginning, communication was excellent and Chris put a lot of time and effort into making sure our plans were understood by him. The pricing was fair and the quality of his work was second to none. Timekeeping was excellent, and he was always open to questions/tweaks as we went along. Chris and his team were highly professional and I honestly can’t recommend them enough. I’ve had some bad experiences historically with work done at my property but Chris is an example of a true professional with integrity. Thank you Chris and the STL team, i’ll be recommending you to all!

Extensions- 26 Mar 2021
I'm so glad that I hired Wright Builders for my job. My visions of the build were made into reality and the quality of work is superb. Charlie and the team were fantastic and liased with me on every aspect of the job. The people used on the job for different trades e.g. plumber,joiner,electrician are all tradesmen who take pride in their work I felt in safe hands with people who knew what they were doing exceptionally well. I can't recommend them highly enough. I have already had so many people even passers by commenting on how fantastic the build looks. The service and commitment has been surpassed at all levels. Hiring a builder who can deliver your dream is very hard to come by. I have not been disappointed and am extremely happy with the outcome. From the initial meeting to discussing plans and making tweeks has been a stress free experience as they know exactly what to do and were polite and considerate. Wright Builders are a 10 out of 10. High quality work with fantastic results we will enjoy for a number of years to come. I feel proud of my home and how it is now and as we have spent so much time at home it makes you appreciate life and the little things. Home is home and when your dreams are delivered by trustworthy builders it's a special moment. Fantastic service and great customer interaction every step of the way.

Kitchen Fitting- 13 Oct 2018
We got a great feeling as soon as we met Steve, a very genuine and approachable guy, and the same for Leighton and the team. Steve did a good job of going through the design with us beforehand and communication was easy and stress free. The job started on time and was completed on time, there were extra touches done that we wouldn't have thought of that we are really pleased with. Any issues were quickly dealt with, i wouldn't hesitate in going to Marsden's Kitchens again or in recommending them to anyone else.

All mess was cleared away, the job was finished very quickly and overall, the team were super helpful and friendly. The cost was very reasonable, and the price quoted, was the price we paid.

Darren came round on a Saturday morning and fitted the TV bracket into a tricky wall material that he had not come across before. It was a clean polite install, had floor coverings down and bought his own hoover to clear up after himself. Will be having him back for other jobs, thanks.

Bricklaying- 10 Jan 2020
Garage conversion - January 2020 I found both Charlie & his Partner to be very professional and knowledgeable they completed brick work and installation of windows and patio doors. The works were completed within the time scale given, they kept me informed all the way and I found them to be extremely reliable, trustworthy and reasonably priced. The site was always left in a clean and tidy condition. I am 100% satisfied with the job undertaken by them and would not hesitate to look at using them again in the future.

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

An extension builder in Derby 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 Derby 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 Derby?

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

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Derby extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
