Quality standards

In our industry, you’re nothing if you can’t prove the quality of your work. At John N Dunn, we’re committed to delivering work of the very highest quality, without fail.

But we also realise that achieving these standards is an ongoing process and we can’t afford to stand still. So we maintain progressive, proven systems for monitoring the quality of our working standards and materials.

And beyond that…

In 1990, our North East Division was the first construction company in the region to obtain BS5750 Part 2 accreditation. It's an achievement the division has built on since and currently operates to ISO9001 standard.

Finally, to ensure we’re matching and exceeding industry standards and staying abreast of developments in our sector, we’re a member of all of the major trade associations and are highly regarded right across the industry.
