About Us

An Irish family business with three and a half decades of quiet excellence.

We’ve been making Irish buildings quieter, warmer and more comfortable since 1989 — from one-bedroom homes to the country’s best-known hotels.

Built on craft, kept by trust.

Wind-Do Seal Ltd is a wholly Irish-owned and managed company. We’ve been the leading Irish manufacturers, suppliers and distributors of quality secondary glazing systems, window sound proofing systems and our own patented fly screens since 1989.

 

We manufacture and fit a premium range of products for both commercial and domestic markets, with an emphasis on quality at an affordable cost. Roughly half of our work is for businesses — hotels, hospitals, government buildings, offices, restaurants — and the other half is private homes.

 

In 1995, in response to client requests from the Irish food sector for a more robust fly screen system, we became the first Irish company to design, patent and produce our own fly screen range and accessories for all window and door types. That same range — refined every year — is still made and fitted by us today.

 

We’re a small enough team that you’ll deal with the same people from survey to handover, and large enough to deliver nationwide. Most of our new work still comes through word-of-mouth from clients we worked with a decade or more ago.

Our values

The simple principles that keep clients coming back.

Quality before quantity

We'd rather fit one job properly this month than rush three. Our systems are designed to disappear into your building and just keep working.

Honest advice

If secondary glazing isn't right for you, we'll say so. Our surveys are free and our quotes are fixed — no upsells, no surprises.

Designed in Ireland

Our fly screens were patented in Ireland. Our secondary glazing is sized to suit Irish window stock — including the sash and casement windows older homes still rely on.

Got a noise, draught or insect problem? Let's solve it.

We’ve been doing this since 1989 — from one-window homes to nationwide hotel rollouts. Tell us about your project and we’ll come back within one working day.

Where you'll find us

Wind-Do Seal operates out of two bases — one in the east, one in the west — so we can reach any address in the Republic of Ireland without long delays or travel surcharges.
