Company History

Global are an award winning home improvements company.

For the past 40 years Global has been providing the widest choice of maintenance-free windows, doors, roofline and flat roofing.

Our history

Global Home Improvements is an award winning home improvements company founded in 1980. For the past 40 years Global has been providing Dublin and the surrounding counties with a combination of high quality craftsmanship and the latest innovations in home improvement products.

Underpinned by quality and customer service, we are dedicated to the highest standards of professionalism from recommending the right products for your home to manufacturing and installing the widest choice of maintenance free windows, doors, roofline, flat roofing, attic insulation and conservatory tiled roofs.

Global has become a market leader and has been recognised among home owners in Ireland as the place to go for high quality home improvements. As a result the company attracts a high volume of repeat and referral business accounting for over 60% of our total sales.

Global is an Irish family owned business and was founded by Tom Shevlin in 1980, originally manufacturing and installing windows and doors. In later years we diversified into other home improvement products and as a result the name was changed from Global Windows to Global Home Improvements to represent the wide range of products and services the company now offers.

They in turn are backed up by our consultant team of architects, engineers and quantity surveyors. The company is headed up by Managing Director Barry Shevlin who has gained invaluable experience throughout the company over the past 17 years.
