How it's done - information about cellar conversion services we offer

We offer a complete solution for clients looking to convert an unused basement or improve an existing failed basement. All our contractors are NSBC (Newton Specialist Basement Contractor) scheme qualified and all our surveyors have passed the rigorous CSSW examinations (Certified Surveyors in Structural Waterproofing). These qualifications ensure everyone on site is competent and that your project is designed, installed and supervised to the highest standards.

Our services fit around five headings:

New basement conversions

Cellar Conversion - InteriorPerfect if you have an existing unused basement and wish to extend your living or working space. Converting this space is likely to add significant value to your building, and help you improve and expand your home or business without needing to move. We can provide one price for a start to finish job including electrics, plumbing, windows, bathrooms, kitchens plastering, decorating and all finishing tasks.

With one competent contractor you'll save the hassle of co-ordinating different companies, reduce the build time and simplify the project costs! We also take care of Building Regulations, Planning Permission, Health and Safety and all structural elements of the cellar conversion build.

We don't need to subcontract labour in as we use our own fully trained and insured basement conversion contractors. You'll be assigned a project manager who will ensure the job runs smoothly from the first day to the last finishing touch. We offer an industry leading insurance backed guarantee on the basement conversion to ensure you have total piece of mind in the future.

Remedial action for failed cellars

Cellar Conversion - InteriorThe UK has lots of failing basement conversions in both domestic and commercial applications. Some basement tanking projects have simply reached the end of their lifespan, some have been badly installed and some have been badly specified, meaning they are unable to withstand the water pressures placed upon them.

We're experts in solving problems with failed cellar conversions and with advances in technology many can be quickly and easily fixed. If your cellar needs extensive repair work, or just a new pump we are happy to quote and give you our advice. With the right technology and knowhow any failed cellar conversion can be watertight and fit for purpose.

Trade customers

For our trade customers, or customers who have their own preferred finishing trades, we're happy to provide a waterproofing solution encompassing all the elements necessary to make your cellar conversion dry. We'll then leave you to undertake the finishing tasks. All work is undertaken by our specialist full-time team of operatives. We do not subcontract work to other companies and you can be assured that your basement conversion project will receive our full attention from start to finish.

The basement conversions still benefits from our 10 year insurance backed guarantee scheme, and we are happy to provide further advice on finishing at any point in your build.

Above ground solutions

Cellar Conversion - InteriorDamp and water ingress can regularly affect houses that do not have cellars. Traditional damp proof courses which are applied by injection methods are unlikely to work on old properties with thick stone walls, such as barns or cottages. Traditional cementitious tanking solutions are time consuming and messy to install.

We supply and fit a range of specialist membranes that seal the damp in the wall out of the internal spaces without affecting the aesthetics of the internal or external wall. Once installed the membranes are completely covered in plaster and cannot be seen.

Installation times are shorter as plaster can be applied to membranes immediately and the reassurance of a physical barrier from damp gives superior lifespan and reliability when compared to traditional methods such as DPC injection or slurry applied tanking.

Our insurance backed guarantee and specialist knowledge make this an increasingly popular solution in the market.

New Build Basement Conversion Solutions

Perfect if you are planning a new build. We provide expert advice on incorporating a basement conversion into your new build, in order to gain the maximum space and value from your land.

Techniques on new build projects vary from converting existing basements and by employing us you will benefit from our specialist industry knowledge. With modern mechanical digging and advances in membrane technology the incorporation of a basement conversion could cost less than you think, whilst adding lots of valuable extra space.

We regularly work with architects to incorporate structural waterproofing into a variety of domestic and commercial projects. Our guarantee scheme can integrate with your NHBC guarantee and offers you piece of mind for the future.
