Converting your cellar is a smart investment as it is an affordable way to expand your living space that will also increase the value of your property. There are lots of different reasons to convert your cellar; some of these cellar conversion ideas are to create extra bedrooms or extra living space, create a home office or even a gym.

Consideration for your cellar conversion

Step 1 – Is your cellar suitable for a conversion?

If you are thinking of having a cellar conversion you will need to find out if your cellar or underfloor is suitable. By organising a basement & cellar survey you will be able to consider all of your possible options and cellar obstacles. You can also gain a better insight towards basement waterproofing regulations and what work is really involved to take the cellar conversion from plan to reality. All of our surveyors are trained to CSSW (Certified Surveyor of Structural Waterproofing) standards and are highly experienced and qualified in the area of cellar conversions.

Step 2 – Preparing your cellar for conversion

You will need to clear out your cellar completely of anything that was previously in it. Depending on the height of your cellar you may need to excavate the floor to increase the height and also make safe the foundations of your property.

Step 3 – Waterproofing your cellar

This is the most important step in any cellar conversion project. If your cellar is not waterproof then water will find a way in which can potentially ruin any upholstery, carpets, wallpaper and decorations you have in your new cellar. You should consider a modern cellar waterproofing system such as water management system which channels the water as it enters the cellar and disposes of it safely.

Step 4 – Finishing your cellar conversion

Depending on what you want to use your newly converted cellar for different considerations need to be made towards plumbing and electrical alterations. If you are planning on using your cellar for storage then it would be an idea to put down waterproof floor tiles or even waterproofing carpet tiles. If you are looking to use your cellar as extra living space then you could put down our specially designed floor waterproofing and plasterboard on the walls so you can paint or wallpaper them.
