Bricklaying- 21 Feb 2024
Kips Builders were the first to reply to my job request and came.out promptly to survey and quote. The communication was clear and concise and a very competitive quote came in just as promptly. Stephen came when promised, completed the work and when the weather prevented him clear communication was received. His work was tidy, excellent repairs made to our old stone wall and a thoroughly decent job all round. I would definitely recommend and use Kips Builders again. Mick NOTTINGHAMSHIRE MIND

Had my patio done by Declan, couldn’t recommend him more. Looking to get him back this year to do another patio area and block pave my drive way. Talked me through the whole job from start to finish, completed the job in good timing. After being messed around by other companies I’d never use anybody again. Great workmanship would definitely recommend!

I recently had an extension and renovation completed by Snowball Invest, and I couldn’t be happier with the results! From start to finish, their team was professional, reliable, and highly skilled. They listened carefully to my vision, offered valuable suggestions, and kept me informed at every stage of the project. The quality of their workmanship is outstanding, with attention to detail that truly transformed my home. The project was completed on time and within budget, despite a few unexpected challenges that they handled with ease. The entire process was stress-free, thanks to their clear communication and dedication. I highly recommend Snowball Invest to anyone looking for top-notch building services!

Extensions- 3 Jul 2024
Very satisfied with Will, Luke and their team. It took 4 months over winter to complete the project using poor architectural drawings supplied but their knowledge and expertise overcame any issues that arose. Communication was excellent where we were updated regularly so we knew what was going on. They ensured everything was tidied up at the end of the day and the work was completed to an excellent standard. They also co-ordinated the plasterer, electrician and plumber so we didn’t have the stress of arranging them ourselves. We are very happy with the finished result and would happily recommend them, thanks guys 😊

What to ask a Southwell extension builder before hiring?

Before hiring an extension builder in Southwell or extension building company in Southwell, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Southwell 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 Southwell 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 Southwell?

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 Southwell 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 Southwell 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.
