How we work

Every client is assigned a project manager at the start of the process. Your project manager will be your main point of contact and will keep you fully involved and informed of progress at every stage of the build, working with you to ensure your project runs smoothly.

We like to operate a clean and tidy site and employ staff who share our values. We always work to fixed price JCT contracts and offer a full ten-year insurance backed guarantee on all of our restoration and renovation work.

FAQs

Have a question? We are here to help!

Building regulations apply to all basement construction. This covers areas such as fire escape routes, ventilation, ceiling height, damp proofing, electrical wiring and water supplies. Underpinning and foundation work may also be needed. You must also consider the Party Wall Act 1996 if other properties adjoin yours and you share walls.
Planning regulations covering the creation of living space in basements is evolving and under review and can vary from county to county and from borough to borough in London. Converting an existing residential cellar or basement into a living space or excavating below the footprint of the original house is, in most cases, unlikely to require planning permission. However, excavating to create a new basement which involves major works, a new separate unit of accommodation and/or alters the external appearance of the house, such as adding a light well, is likely to require planning permission. If you live in a listed building you are likely to need consent for internal or external work. In all circumstances you are advised to contact your local planning authority for guidance on local policy before starting any work. At Cool Basements we have a dedicated team of architects and planning consultants who will advise and take care of planning requirements on your behalf.
Our aim is to give our customers complete peace of mind so we go above and beyond the usual guarantees. We work to strict JCT building contracts, set out by the joint Contracts Tribunal, which means we ensure every element of the build is accounted for and completed on schedule. In addition, we can offer a full ten-year insurance backed guarantee on all our basement constructions, which covers labour and materials. We use state-of-the-art tanking systems that come with a ten-year warranty and we offer a one-year warranty on minor defects such as cracking.
Adding a basement to your property can bring fantastic benefits. We can help you to explore the options so you get the most out of your new living space. The first step is to get in touch. We will then arrange a free site survey and initial consultation to understand more about your requirements. Every client is assigned with a dedicated project manager who will manage your build from the design stage through the planning process to the final construction and fit out.
