About Crystal Damp Proofing & Basements
Why Choose Crystal Damp Proofing & Basements?
Crystal Damp Proofing & Basements is a family-run business specialising in reliable, long-term damp solutions — and we take pride in making the process completely stress-free for our clients. With over 20 years of experience in the construction and waterproofing industry, we’ve built up the expertise to diagnose and treat a wide range of damp‑related problems. Over the years, as construction methods have evolved, so have we — constantly refining our techniques and adopting the latest technologies to tackle even the most persistent moisture issues.
Specialists in Damp
We use cutting-edge crystalline injection technology, a modern method that creates a permanent, mineral-based damp-proof barrier within walls. This technique is eco-friendly, cost-effective, and long-lasting — providing a real solution rather than a temporary fix.
Basement Waterproofing Experts
In addition to treating damp in walls, we are specialists in basement and cellar waterproofing. Whether your underground space is used for storage or being converted into a liveable room, we design and install waterproofing systems that meet BS 8102:2022 standards.
Where We Work
Based in Croydon, we operate across London and the South-East, typically within a 50-mile radius. We serve a wide variety of properties — from domestic homes to commercial premises like schools, pubs, shops, and offices.
Our Approach
- Customer‑first: We treat every property — and every customer — with respect and care, tailoring our advice and solutions to suit your budget and needs.
- Permanent Solutions: We don’t believe in quick fixes. Our crystalline injections and waterproofing systems are designed to last, giving you peace of mind.
- Eco‑friendly: Our damp proofing technology uses mineral‑based systems that are more environmentally friendly than many traditional chemical alternatives.

Customer's Testimonials
What People Say About Us
They carried out basement damp-proofing for us and did a fantastic job. I had a lot of issues with damp and the basement was in very poor condition, but fortunately I found this company.
They did an excellent job — very professional, courteous, and always on time. I also used them for my daughter’s flat in Brighton.
Once again, they did a fantastic job. She also had serious damp problems, which is common for anyone living near the sea, but they managed to resolve everything and delivered a really high-quality finish.
Well done — I highly recommend them.
Don’t often give reviews, but after several botched attempts to fix the damp problem in our flat by other companies and spending a considerable amount of money, Lucasz finally managed to solve the problem.
There were multiple issues & Lukasz sorted them all out, from a dodgy DPC, damaged render, installing additional ventilation etc.
So big thanks for finally getting rid of all that horrible black mould.
We used Crystal Damp Proofing for comprehensive damp-proofing work on our ground floor property, including DPC injections and waterproof render systems. From the first detailed consultation through to completion, their professionalism and workmanship were outstanding. Although we had cheaper quotes, the quality Crystal delivered was on another level — worth every penny. They were friendly, reliable, and exceptionally thorough. What we thought would be a one-month job became three due to hidden issues, but they handled everything brilliantly. I genuinely cannot recommend Crystal Damp Proofing enough.
