Transform your cellar into a practical living space

Unused cellars and vaults often sit dark and forgotten, but we convert them into bright, comfortable rooms designed for everyday use. With Waterproof Systems Ltd, these spaces can become bedrooms, gyms, home cinemas, or wine cellars, tailored to your lifestyle. Our team works on both period and modern properties, ensuring every conversion is carefully designed to suit the building. We combine specialist damp proofing and waterproofing to keep your space dry and usable throughout the year. From a quiet home office to a family playroom, we create practical solutions that add comfort and extra value without altering your property’s footprint.

Tailored cellar conversion solutions for homes and businesses 

Waterproof Systems Ltd delivers cellar conversions for both residential and commercial properties, with a focus on safety, functionality, and design quality. Our team is experienced in working with heritage buildings, carefully retaining original features such as brick arches and vaulted ceilings where possible. Each project is fully considered from the ground up, including lighting, ventilation, and insulation, to ensure the space feels welcoming and usable. Our insured guarantee covers all work, giving you confidence at every stage. For property owners, we provide compliant, long-lasting conversions built to current standards.

Unlock the hidden potential of your property

A cellar conversion is a practical way to gain extra living or storage space without extending your home. This is especially valuable in urban areas where limited space exists. Our work helps increase property appeal while preserving original character where present. With effective damp proofing and energy-efficient upgrades, your cellar becomes a comfortable, year-round space. We help you turn underused areas into a valuable asset for both home and business use. 

Giles and his team provided an excellent service. Fully investigated the problem and recommended an appropriate solution. They regularly updated me on each phase of the work which was completed to the highest standard. They were considerate and helpful throughout. Highly recommended company

Giles and the whole team were super friendly and professional. Tom is the tidiest workman I’ve ever met! They have had to do multiple stints to get the work done with the least impact on me, and each time they are so easy to have in the home. Always super respectful.
