Case Study

We provide sealant applications, fire proofing and waterproofing for the construction industry. Our core business is sealant application. I quote for works to be carried out, conduct risk assessments and project manage the work from start to finish to ensure a high quality of work.

Our work could involve anything from sealing around marble worktops in a domestic property to large commercial sites that require floor joints or glass screens. We often use a mobile elevated working platform and sometimes a specialist abseil team.

Operatives are supplied with a company vehicle and jobs are sent daily to the satnav. They pick up materials from our network of stockists and get to site for 8am. Site inductions are carried out before an operative can start any site work. They look at the scope of works and areas and access.

After this they complete their work, clear up any waste materials, measure up works completed and fill in a job sheet. They report back to the client with feedback and any issues. Before leaving the site they report back to us by phone or the satnav system to arrange if they need to return the next day or have a new job.

How did you get started?

I progressed from working as a skilled person on the tools operating as a sealant applicator to heading up a sealant department within a large construction company.

What do you enjoy about your job?

I like the freedom to make my own decisions and choosing the type of work I do and customers I work for. In this role I can assess the work situation first and then decide if I’d like to do it, based on many factors. These would include issues of site condition, health and safety and working practices imposed by a particular construction site. 

What skills do you need?

I’ve acquired accredited construction qualifications to become an assessor for sealant applicators. I’ve also developed skills in running my own business and managing my employees. I have achieved this through training courses in management skills, appraisals, and employment law. As a company we have been awarded The Skills Pledge, we are an approved Arob Master, members of the Association of Sealant Applicators and winners of the Evening Echo Business Awards.

What makes you proud?

Remaining in business, keeping people employed, despite a major recession in the construction industry. I’d like to think I’m continuing to improve my business and providing my customers with a very good service. 

Any on how to get into construction?

Construction is a very good industry to work in if you’re prepared to work hard. The industry offers opportunities to develop your hands-on skills and can provide a great route for more training if you wish to develop those skills to a higher level. I’m concerned about the shortage of skilled labour now and in the future. We should provide opportunities for training to ensure we can meet the future demand for development in the construction industry.

Qualifications & Training

The Association of Sealant Applicators runs its own apprenticeship scheme, which leads to an NVQ Level 2 in specialist installation occupations – joint sealant application. You must be at least 18 years old to apply. 

The two-year apprenticeship includes a combination of 18 days' off-the-job training, 20 days' on-site training with an employer and five days' on-site assessment. Apprentices spend the remainder of the two years gaining experience on site and work towards the following qualifications:

  • NVQ Level 2 in Joint Sealant Application
  • CSCS Card
  • IPAF Certificated Mobile Access Plant Operator Scissor Lift
  • IPAF Certificated Mobile Access Plant Operator Boom Lift
  • PLASMA Certificated Mobile Tower Erection and Dismantler
  • Abrasive Wheel and Diamond Blade Certificated
  • First Aid at Work Certificated

It’s a good idea to have at least three to six months of on-site experience with an employer before starting this construction apprenticeship. If you haven’t worked in construction before you can start out as a labourer and your employer might train you in sealant application.
