FAQs for Basement Renovation & Refurbishment London

How can I maximise the use of the small space under my house?

When it comes to basement renovation in London, extending beyond the boundaries of your house, and an open excavation into the garden can create a larger basement. For basement contractors in London, conversions within the existing boundaries are preferable, but getting approval for an extended boundary is always necessary.

How long would a typical basement renovation take to complete?

Basement construction work in London can take a number of weeks and depends on basement sizes. For any basement renovation, time is needed for completion of underpinning, excavating and ensuring the area is watertight. These are big changes to a home, so let our basement contractors make your London home your dream property.

We live in a terrace house. Can we do a basement renovation?

Yes but basement construction work should be consulted on with neighbours, especially as terraced houses include party walls, or walls that are shared between you and your neighbours. Before you do any work you must have the consent of your neighbours.

How can I get adequate light into my basement?

For basement  renovations in London that open onto a garden, installing floor to ceiling sliding or bi-fold doors can let in natural light. If your basement is surrounded by soil,our basement contractors in London can install solar tubes to channel natural light into the room.

Our basement refurbishment work in London often includes open plan basements with fewer dividing walls, which aid the flow of natural light throughout the space. For a light filled basement construction at your London home, select a light colour palette when painting and decorating, and/or a large mirror to reflect light.

Do I need basement waterproof ?

Basement waterproofing in London properties is below ground level work, so water will naturally enter a building through the walls. Our basement contractors in London will waterproof the basement by sealing the walls using a surface coating. In basement construction work, this is known as ‘tanking’. This basement waterproofing in London properties doesn’t remove water, it creates a barrier between the wall and the water. Our basement contractors in London will get that done for you.

How can I ventilate my basement to prevent a build up of mould?

For all basement construction projects in London, ventilation is a critical factor. Using natural ventilation by installing windows that can open and close, allow our basement contractors in London to create cross-ventilation.

With a professionally done basement construction in London, mechanical ventilation can be achieved through the installation of an exhaust fan to remove moisture and pollutants from the air, equipment often equipped with a humidity sensor to activate the fan when moisture is detected. Our basement contractors in London can ensure the fan is vented to the outside of your building.

For customers who want basement finishing in their London home because of damage done by old materials, we will get it done.

Windows, Wells, & Staircases Installation
