We're building the future of construction
Introducing Chalkstring
Sarah Crawford, Co-Founder & Managing Director at Chalkstring, gives a short overview of our business and what makes us tick.

Our story
Chalkstring was created in direct response to the challenges specialist subcontractors face when managing project costs. With first-hand industry experience at its core, the idea was to streamline processes, maximise efficiency and boost profit – all within a single, integrated platform.
The functionality was carefully scoped to meet the real needs of subcontractors – from estimating through to final account – tackling everyday issues with practical, easy-to-use tools. The result is a cost management solution purpose-built for the construction industry.
From there, our management team formed and we now have millions of pounds worth of project costs being handled daily by Chalkstring, across a range of specialist subcontracting trades.
We are committed to helping our clients' business’ succeed and believe in fostering long-standing relationships. We listen and respond to product feedback. And we continually deliver unique solutions to construction industry problems, giving our clients a competitive edge.
We’re building both the future of Chalkstring and the future of construction.
