If you’re looking for a trustworthy and transparent waterproofing and conversion specialist, you’ve come to the right place – and here are a few more reasons to choose us...
Our basement waterproofing contractors have all undergone extensive training with Triton Chemicals, a leading supplier of superior standard waterproofing materials – making us an approved contractor and genuine specialist.
Our contractors also offer a friendly and professional service at all times, keeping noise, mess and disruption to an absolute minimum.
Because of our approved contractor status for Triton waterproofing systems, we’re able to offer their 10 year insurance backed guarantee on all structural and cellar waterproofing work, alongside our own 10 year guarantee.
All second fix work for your cellar conversions will be backed by a 12 month guaranteed issued by Below Ground Interiors.
Sometimes cellar conversions can fail, due to poor initial waterproofing, subsidence or underground vibrations caused by heavy traffic, trains etc. We’re experts in identifying the problem and designing a repair solution in these cases.
So if you need help to repair a failed basement conversion, we’ll be happy to help you restore your cellar into a dry, functional room once more.
We offer an end-to-end service, from initial concept designs, to waterproofing and 2nd fix, creating a completely bespoke cellar conversion, tailored to your specific needs – we’ll make the best use of the space for your budget.
If you’re looking for something a little different, we can also create beautiful spiral wine cellars or convert your cellar for any purpose.
Our contractors never cut corners, and all waterproofing and conversion work is completed to the highest possible quality, complying with all health and safety regulations and delivered at a competitive price.
You’ll receive an official report from an independent CSSW surveyor to ensure any work undertaken by our cellar conversion specialists and basement waterproofing contractors is designed and completed to the highest standards.
