Hartlepool firm Ableclean can proudly look back on six months of continuous growth at a time when others are struggling to survive.
But managing director David Haggan is not resting on his laurels. He said: "I am looking to buy other companies.
"There are 100 companies in this country that are vulnerable. They are cleaning companies which are vulnerable and are in danger of going under."
Ableclean is going from strength to strength and is ranked as one of the top 70 in the UK.
Mr Haggan said: "We employ nearly 400 people all over the country and we have expanded in the last six months. We have taken a lot of major contracts on."
Ableclean operates from Lowthian Road and was founded in 1990 before being taken over in 1996 by Mr Haggan.
He now runs the firm with his two sons David and Lee.
There's more good news. The company has gained the ISO 9001 2008 certification to ensure customers receive excellent quality of service.
The firm handles everything from small contracts to huge orders for major companies.
Their services can range from daily office cleaning to window cleaning, contract cleaning to one-off graffiti removal.
Mr Haggan added: "One aspect of the work which is becoming more and more in demand is builders cleans which is going in after building work and giving the area a thorough clean.
"We have achieved our success after a lot of hard work and dedication.
"We pride ourselves on our utmost commitment to clients, not only to win contracts but also to meet and exceed their contracts on an ongoing basis."
