Building services specialist guarantees future following management buyout
Stockport-based decarbonisation and building services design consultancy, S I Sealy, has completed a management buyout, for an undisclosed sum.
Daniel Madden, a director of the company since 2016, is now the sole director, having acquired fellow director David Stafford’s shares through the MBO and now owns 100% of S I Sealy & Associates.
David Stafford stands down as a director of the business to become a specialist advisor.
He officially retires in April 2026 and for the next 12 months, David and Daniel will finesse and implement a long term plan for growth.
During this period, the pair will work on transitioning key projects and business activities to Daniel. David’s advisory role will gradually reduce over the year.
They will continue with S I Sealy’s people-focused approach as their ‘home grown’, internal talent steps into wider roles. One outcome of this focus will be the creation of a strong management support team around Daniel.

Enjoying a relationship that spans 20 years, David and Daniel have significantly grown the business over this time. On retirement in 2026, David will have dedicated 40 years’ service to the company.
Daniel Madden said: “Staying independent, focused, and strong will remain our strategy for the foreseeable future as we continue to work across all sectors.
“Key sectors like healthcare and education where we have achieved market leadership will, of course, remain important as we attract new commercial, industrial, leisure, and residential projects.”
He added: “Remaining efficient and competitive in how we deliver building services design solutions which are ahead of the curve, will keep us profitable, sustainable and people focused. Our plans for growth give our fantastic team an opportunity to capitalise on our success as we continue to serve our loyal client base.
“David’s contribution has been instrumental in developing the company into what it is today, and I’d like to thank and congratulate him on his 40 years of dedication to the company.
“His guidance to the team and me, personally, especially as we’ve planned his exit over the last few years, has been and continues to be incredible.”
S I Sealy was formed 76 years ago. The management buyout gives the business long term security, stability and independence, while continuing to innovate and develop.
