The Protec Group was first launched in 1996 as a windows company under the name Protec Ventanas S.L.

By 2000, the founder, owner and CEO, André Jensen, had created a second company focused on the construction sector. Since then building works have been undertaken by Protec Construcciones S.L.

In 2002 Velisa Negocios S.L. was formed as an autonomous Real Estate company but still operating under the umbrella of the Protec group. This enabled us to cover a new sector with additional services for our clients who are  always our main priority.

Last but not least, a new pillar for the group was established with CT1 Spain a company dedicated to the acquisition and distribution of high-quality construction products unavailable in mainland Spain. This company operates nationwide and is expanding yearly.

Now we would like to introduce ourselves to you. We see ourselves as a team, in which individuals are connected to each other as an efficient group of professionals. We offer, with commitment and passion, an exceptional and comprehensive service to all our clients. We are a thriving company within the building sector because we consistently produce outstanding results which will last for generations. Our priority is to always provide our clients with the highest quality products and services available.

Here are our trusted team members who are always willing and available to listen to your enquiries.
