“To be the first choice Construction & Maintenance contractor by providing exceptional customer care for the discerning client”

At Adamson Construction we have a vision of improving the standard of service a customer receives. We have built on this philosophy by selecting staff with similar aspirations and reinforcing this through training and guidance. We will not walk away from a problem and we will not be satisfied until you are.


At Adamson Construction we pride ourselves on customer care and go the extra mile, ensuring a user experience that is exceptional, with high-quality finishes to exceed all expectations. We maintain a clear focus on loyalty, trust and aftercare – this is why our customers stay with us. 

Our Values – to CARE

C – Care about the Client
A – Accreditations; A strong SHEQ culture
R – Relationship, respect and trust before profit
E – Excellence in Quality


Our Sole aim is to provide a service that our customers can completely rely on to deliver their construction, building and refurbishment needs, from full project management as the principal contractor to elements of sub-contracted works.

We are committed to providing you with the highest quality of service at all times – not only in the final result but throughout the project, this is reflected in our multitude of accreditations and certifications.

We believe we set the standard which a construction company should attain; through our collaborative working, regular communications and aftercare.


Adamson Construction was formed in 1989. The company has been located in Slough for the duration of its history and has established many long standing relationships, both on Slough trading estate and nationally, resulting in an ever growing client base. The wealth of experience gained in this time is considerable and Adamson Construction has established a wide variety of skills and abilities that allow us to undertake most jobs in many markets. 

Shortly after formation, the relationships established led to repeat maintenance work such as flooring, groundwork, concreting, painting & decorating. This soon developed into a much wider range of services which have been maintained until the present day and Adamson Construction now takes on many different projects because of the diversity of abilities and knowledge it possesses. 

The project management skills that have been developed have enabled the company to combine its resources and capabilities with other specialist sub-contractors, which allow the smooth running of projects. Adamson Construction has grown year by year and now employs a multi-skilled workforce, with the ability to project manage large projects, yet are small enough to offer tailor made services which genuinely satisfy every clients’ differing requirements.
