We’re all about you
We’re all about you
Transforming the look of your home, energy performance and security and boosting the value of your home is what we do. Our why is you. Our customers. We’re all about you. That’s the difference, the Global difference.
We’re all about you
Global’s founder, Tom Shevlin, set the bar high in 1980 when he established the company’s values of quality and customer service. The brand has continued to evolve while remaining committed to these core values. It’s all about the customer experience – before, during and after installation.
Unmatched aftercare service
Most companies have hidden charges in their guarantees, we don’t. We see every relationship with a new customer as entering a life-long partnership and offer free guarantees as added value. We want to ensure you enjoy complete peace of mind knowing you’ll receive the best level of service and care long after installation.
Trusted for 45 years
We’re proudly Ireland’s longest-established home improvements company – celebrating our milestone 45th anniversary in 2025! As a family-owned Irish business, we understand our customers and the importance of delivering on our promises.
For four decades, we’ve transformed thousands of customers homes (and lives!) as the proven reliable, safe choice. We offer expertly fitted quality solutions that last and stay looking great with minimal maintenance ensuring your home retains its value for years to come.
Made in Dublin, with care
Backed by the Guaranteed Irish symbol of trust, we’re one of the last Irish home improvement companies to manufacture our own windows and doors. At our factory in Glasnevin, Dublin, we tailor-make your windows and doors to perfectly fit your home. We source the best quality materials, locally whenever possible. We consider every detail so that we can stand over our unmatched guarantees – in other words, our promise to you.
We don’t use sub-contractors
Our installers are highly trained craftspeople, employed directly by us so they go the extra mile for you. You will be treated with care and respect and your home will be left spotless. Our training programs ensure our team remain on top of their professional game. You enjoy direct access to us before, during and after installation so any little niggles you may have can be fixed immediately to your satisfaction.

We continue to strive for awards because we care about quality and standards – and we know you do too. From Guaranteed Irish ‘Best Retailer’ 2024 to Q Mark Quality certification to Gold Trusted Service Awards and International Health & Safety standard, you are guaranteed the highest quality and care throughout your home transformation journey.

Yes, we install a wide range of home improvement solutions including roofline, fascia and soffit and flat roofs.
We only supply and fit as our installation system is an integral part of our overall product performance and can only be fitted by Global trained installers. Furthermore, as our guarantee covers installation, it would not make sense to buy the product only. We can not guarantee supply only as we would not be installing, and installation is crucially important.
Yes we do, but it must be linked to windows or doors that we are installing. In other words, if you want a window or door opening made bigger or smaller or you require a concrete lintel, step, concrete bases etc, we can do this as we have our own engineers and in-house expertise.
