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

It was year 2000 the founder, owner and CEO André Jensen created a second company, namely in the construction sector, which immediately reflected the ethos of the group, following the need to differenciate the two sectors. These building works were and continue to be undertaken by Protec Construcciones S.L.

In the year 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 not available so far 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 complete 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.

Taking into account our corporate philosophy, these are our trusted team members who are always willing and available to liaise with you:
