When does a basement need renovating?

  • Rising damp from the floor
  • Salt deposits on the walls
  • Water after heavy rain
  • Dark space that never gets used

What the basement renovation includes

  • Internal waterproofing

    A damp barrier on the walls and slab, applied from the inside.

  • Drainage and pumping

    Perimeter channels and a sump pump where the water calls for it.

  • Mechanical ventilation

    Forced extraction to refresh the air and prevent condensation.

  • Insulation and finishes

    Lined walls and an insulated floor for a dry, comfortable basement.

  • Lighting and electrics

    New circuits and lighting designed for a space without windows.

  • Fitted out for its use

    Wine cellar, gym, games room or workshop, each with the right finishes.

From diagnosis to finished basement

We start with a visit to find where the damp comes from, how the basement ventilates and how much headroom it has. Based on the use you have in mind, we prepare a detailed written quote.

The site manager follows a strict order: waterproofing and drainage, ventilation and services, then insulation and finishes.

We hand over a basement that is dry and clean, with lighting and ventilation tested, ready for the use you have chosen.

Frequently asked questions

01

Does the damp need fixing before the basement is fitted out?

Always. First we find out whether the water comes from the ground, a leak or condensation, and apply the right solution. Skip that step and the finishes will end up damaged.

02

Can a basement be used as a bedroom?

For habitable use the CTE requires daylight, ventilation and a minimum ceiling height, and local planning must allow it. We check this on the visit; if it isn't possible, we suggest uses such as a gym, wine cellar or play area.

03

How much does a complete renovation cost?

There is no single price. The estimate depends on the condition and size of the home, the scope of the project, materials and work required. Tell us your idea so we can assess your specific case.

04

How long does a renovation take?

It depends on the type of home, the scope of the work and the project's constraints. Once we have studied the renovation, we can give you a more accurate estimate.

05

Can a home be renovated while people still live in it?

It depends on the scope, estimated duration and condition of the home. When we study the project, we will assess whether it is feasible and what precautions or alternatives should be considered.

06

How can I request an estimate?

Choose what you want to renovate, tell us whether the work is partial or complete, and leave your name, phone number and email. This lets us provide initial guidance. You can also write to us directly on WhatsApp.
