DASA: Leading the Way in Drainage Solutions

Founded in 1982 by Darryl Gartley, DASA began as a specialist provider of essential property services, operating from small premises in Manchester. From the outset, Darryl focused on delivering exceptional service, embracing new technologies, and building a team of skilled professionals to uphold the highest standards.

As a family-run business, DASA’s success is built on those strong values of innovation, expertise, and outstanding customer care. 

Today, DASA is a trusted name across the business, residential, and insurance sectors. With ongoing investment in technology and a commitment to excellence, we deliver reliable, high-quality solutions that consistently exceed our customers’ expectations.

The DASA Difference

At DASA, continuous investment and innovation drive everything we do. For over 40 years, we’ve delivered forward-thinking solutions, underpinned by thousands of hours of specialist training, to ensure exceptional service across the residential, business, and insurance sectors.

Our engineers are among the most skilled in the industry, prompt, professional, and equipped with the latest technology to quickly diagnose and resolve a wide range of drainage and plumbing issues. From routine repairs to complex challenges, we respond with speed and precision.

We’re here whenever you need us, 24 hours a day, 365 days a year, delivering reliable maintenance, repairs, and installation services with minimal disruption.

By combining deep technical expertise with a relentless focus on innovation, DASA provides smarter, more sustainable solutions that deliver long-term value for every customer.

Sustainability & ESG: Leading the Way

At DASA, sustainability and ESG are embedded in everything we do. As CEO Darryl Gartley states, “Underground services don’t have to cost the Earth.” For over 40 years, we’ve remained ahead of the curve, ensuring our services benefit both clients and the environment.

Our Head Office runs entirely on renewable energy, reflecting our commitment to sustainable operations. We conduct Life Cycle Analysis on claims to understand and minimise their environmental impact. By reducing site visits, using local contractors, and investing in cutting-edge technology, we lower emissions while improving service efficiency. Our Zero to Landfill policy ensures all waste is either treated or recycled.

DASA upholds the highest ESG standards, working with CHAS, Constructionline, and Safecontractor. Our Science Based Target has been officially recognised. We also give back to our communities, proudly supporting charitable organisations such as the Trussell Trust.
