About Us

Since our formation in 1993, Williams Sealants have dedicated ourselves in providing a high quality product at a competitive price.

Historically, sealant application was carried out by any tradesman. However as bespoke design began to incorporate metals, stone, glass, timber and brickwork, the need for quality sealant application became apparent.

Mastic Man has evolved from a product of that need, continually developing on skills in the commercial and domestic market.



Farnborough Business Centre

This prestigious development is one of two remaining World War 1 air bus shelters brought back to its former glory.

This site is part of the on-going rejuvination to the business park and surrounding area.

As part of this project we were asked to provide a flexible, water-resistant sealant to the junction of the concrete feet that supported this enormous structure.

The Mountbatten Building – Southampton University

This project commenced for us in November 2007, and was completed by April 2008.

With over four and a half thousand linear meters to structural glazing, this is a terrific example of how technology and skills in sealant application has developed to keep up with progressive building design

Pall Europe Limited – Portsmouth

This project is a great example of the diversity of work that Mastic Man has enjoyed over the past 15 years.

This was the complete facelift of three elevations of the Pall Europe Building in late 2004.

Access to the 22 storey building was via the use of 12m cradles suspended from the roof of the building. With the removal of the existing sealant and replacement of new, the works were carried out over a 10 week period.

Typical Housing Development

As with Typical Housing Development, with many sub-contractors, we have enjoyed a share of the housing boom over the past decade.

No more so can we see the need for gun applied sealants than the housing industry. With the constant updating of NHBC regulations in acoustic and thermal air testing to reduce gases and heating efficiency, our service is energy efficient and cost effective.
