At Crownstone Group, we work with residential and commercial clients to survey, plan and construct basements as well as working in drainage and damp prevention and protection.
Whatever the work undertaken, we place our reputation and the happiness of our clients above all else. Our team adhere to our core values of fairness, humanity, excellence and collaboration in all that we do.
Everything we do is to the highest possible standards, both in terms of quality and in terms of adhering to building regulations and British Standards. Every basement we work on and every damp and drainage issue we address is resolved and left robustly watertight – as you would hope it would be.
