About Us

Established in 1997, Clear Line quickly built up a solid reputation in the curtain wall installation market.

In 2001 Clear Line expanded its installation services to the European market and beyond. We extended our services the following year to cover the building maintenance market. This was a natural progression for Clear Line, utilising valuable skills gained from the installation business to develop innovative approaches to building maintenance.

Clear Line have worked hard to maintain an exceptional health and safety record. Achieving certification of ISO 9001, ISO 14001 and ISO 45001, Achilles Building Confidence and CHAS has enabled us to work with a wide range of Main Contractors and Facilities Managers in numerous sectors.

The building maintenance arm of Clear Line continues to stay ahead of the curve, developing bespoke solutions for a range of clients. We have a strong team of experienced managers and designers who have developed a variety of services to deal with a wide array of client issues. We solve problems ranging from simple glazing replacements and malfunctioning doors, to full building envelope refurbishment.  Our adaptability and willingness to go the extra mile for our clients has rewarded us with a strong position in this market.

Our ability to offer complex lifting solutions is assisted by our own equipment fleet.

This ranges from minicranes and glass vacuum suckers to specialist Winlet Glass Installation Robots that overcome more challenging site conditions where crane access is not possible or practical.

Our in-house design team, based at our Headquarters in Sheffield, provides us with greater control in ensuring our product is to brief and on time.

Our investment in the latest CAD software and high-end equipment gives our designers the flexibility to offer fast production of efficient schemes and schedules for projects.

Clear Line also utilise this design capability to undertake continuous R&D into new bespoke access methods and material handling systems, in an effort to make more streamlined and effective work.

By working closely with our project managers the team anticipates any unique challenges before they arise and starts work on solutions.

Building with complex architecture


Clear Line recognise that building design is constantly changing to meet new challenges. We continually seek to enhance our design capabilities by participating in industry conferences and events, which help ensure we are always at the forefront of developing technology.

As part of our commitment to ensure Clear Line are working in accordance with the latest industry expertise, we regularly organise a number of training courses for staff to undertake, which cover a range of fields including integrated façade & joint design, principles of weathertightness and different materials performance.
