Dalgan are a family-run business who compete on the international level. We cover a wide variety of clients throughout Ireland, north and south, and produce excellent quality products for all sorts of clients. There are no damaged or aged doors and windows we can't replace easily, our trained engineers will minimise any disruption to your home or business. We supply windows and doors in aluminium and PVC, giving you the most modern materials which offer many advantages in terms of longevity, maintenance, and appearance, and style them to match your environment.
Window coating and argon gas spacing between panes of glass multiply the advantages of your Dalgan window. Regardless of the environment for your windows and doors, we build to last in good and bad weather, sun snow or rain, year after year. Our windows won't ever need painting and their upkeep is as simple as a wipe with a soapy cloth. Dalgan is the name for experience that you can trust, reliability is our central value. Every client is different, and everything we produce is made to order when asked for, whether that's a contemporary look or something more traditional.
We've been in business for forty years because we have a reputation for looking after our customers and maintaining a top quality standard. Working hand in hand with you is how we get the results and success that have made us the people to call for windows and doors.
We'd heard that Dalgan were good but wow! You wouldn't know the place after they were done. The doors are replaced and the new conservatory gives us lots of space to watch telly and play with the kids. Good work.
