What our Clients Say

We at 20/20 Window & Glazing Systems have engaged and worked with Excell Sealants for many years since our company was formed in 2009. As our company grew, we recognised that we would be requiring the services of quality silicone applicants for our larger contracts. Excell Sealants were a locally based company and provided a service which met our needs, in both a timely and professional manner. Excell Sealants have been an integral part of our ability to complete many projects throughout the country. They have always been very helpful and understanding to our requirements with regard to timelines and resources when under pressure to complete these projects.


I would have no hesitation in recommending Excell Sealants as their work is always excellent and professional.

Ken Matson
Director, 20/20 Window & Glazing Systems

I have had the pleasure of working with Excell on a number of projects over the past number of years. In all cases the works completed by the Excell team was completed to a very high standard and in a timely manner. I have had feedback from our clients and design teams regarding the quality of the mastic works carried out on our projects and this is a testament to the professions working at Excell. The team are very flexible and work with our site teams to complete projects on time for us, even when timelines are reduced due to site constraints.


I would have no reservations in recommending Excell for projects both within our company and others in the future.

We have recently finished a commercial office project in the brand-new mixed development in Cherrywood in South County Dublin. On this project we engaged Excell Raised Access Flooring to carry out a package of flooring. This was a large package of flooring spread over 5 storeys in Block F2 of the commercial campus in Cherrywood. It was a pleasure to work with Excell from the outset, their professionalism and workmanship was visible from the start. The entire installation ran smoothly thanks to excellent collaboration between Excell's site team and our site management. 


I would happily recommend Excell for projects both with our company and others in the future.

I got to know Excell Sealants from contacts in the construction sector and I have found them to be an exemplary company to work together with. I found their service to be excellent in planning projects and having staff available to complete large and small scale projects. Its great when a company and its employees (that I have met) all take pride in their work and want to ensure what they are doing has a quality finish and meets the clients requests.

Monami recently engaged Excell’s Raised Access Flooring division to supply and install a PSA MOB Medium Grade Corner Lock system within a global logistics development in Shannon, Co. Clare. This was Monami’s first encounter with this particular Excell branch. We have engaged Excell’s silicone services numerous times in the past and have always had a great experience as they continue to deliver on budget, to the highest quality and always meet our requirements. Our past experiences with their company made our decision with regards to a RAF sub-contractor simple. 
Monami would highly recommend Excell Raised Access Flooring. It was a pleasure to work with them on this project as everything was delivered as promised, in addition to value being added, which exceeded our expectations from the outset.
