Norva24 Grenland

Norva24 Grenland offers a wide range of services within operation and maintenance, industrial and facade cleaning, high pressure flushing, pipe inspection, concrete rehabilitation and vacuum suction. The machines and vehicles are half the job, the rest our professional operators take care off. A good professional environment and equipment investments are two of the reasons we are constantly developing.

Norva24 was established in 2015, when a wide range of small local companies merged and formed a larger group across regions.

Today, we provide a wide range of services to the industrial and corporate market, government agencies and private actors.

Today, we are the largest in the Nordic region in our field of service, and have a wealth of customers - big and small.

Young company - long story

Despite Norva24's young age, our story extends far back in time. Our oldest local department started up with septic services on horse and carriage - already in 1919.

All our departments have their unique and exciting history, and together we have approx. 300 years of experience!

Wide range of services and quality in every aspect

Our multitude of skilled employees make every effort to deliver top quality work - at the agreed time.

We have a wide range of services in the field of high pressure cleaning, drainage, tank cleaning, piping and industrial services.

We clear passage where it is tight, flush where it is dirty and empty where it is full - we maintain and clean up.

Local knowledge and national strength

Our local presence is important to provide the best service to all our customers.

We know the local markets well and quickly fit into place when the need arises.

At the same time, our national breadth enables us to offer our customers even more services than before.

You can count on us - we will always help!
