Before starting any basement extension work, it’s best to check if you are permitted to do so. If you’re refurbishing an already-existing basement, you might no longer need a permit. You’ll have to talk to your neighbors too if your house is a terraced or semi-detached house.
The next thing you have to check is whether there are any pipes on the ground that will prevent the digging and construction of your basement. It’s important to see if your area is fit for excavation work and whether it’s close or far from the road as this can help speed up or impede excavation.
Waterproofing your basement is also essential. Not long ago, basements were constructed simply by excavation and cement finishing, without all the necessary waterproofing measures. In this case, the basement becomes prone to leaks after years. When this happens, the basement becomes at risk during a flood, which causes the basement to become moist and damp.
To know if your basement is safe for extension, contact specialist building services in London to have your property assessed. They will not only make sure the construction is safe and well-executed, they will also make sure your basement goals are realized.
