5.0 ★ from verified Google reviews · 23 years installing across Ireland

I would have absolutely no hesitation in recommending Airtight Windows to anyone looking to upgrade windows. Owen was friendly and professional from start to finish, much better value than any of the other companies who quoted. Installation went smoothly and Anthony cleaned up any mess that was made during the process. Very pleasant to deal with and we are delighted with the result!

Airtight Window Systems did an excellent job installing our new front door and casement windows. From the first contact through to the final fit and finish, their team was professional, punctual, and clearly knew what they were doing. The workmanship is top-notch. Everything feels solid, looks great, and the casement windows open and close smoothly.

Would highly recommend Owen and his crew! Felt really looked after from the initial email, to Owen coming out to measure and quote for our doors and windows. We received our quote on the same day! Took 6 weeks from ordering for the doors and windows to arrive and they were out just days after! The team installing were amazing, they arrived right on the dot each morning and had the entire house done in 3 days. Everything went so smoothly, talk about stress free!

Excellent company and an absolute pleasure to deal with. My family have had three front door installations by Airtight and all three were flawless from start to finish. Highly recommended.

This is the second job I have had done with Owen — his advice and guidance on the best solution is honest and the best. Prices are very keen. The door was installed by Anthony and what a brilliant job he did, with no mess, and happily did some other related jobs that had been requested. Very pleasant and trustworthy workmen to have around the house. Super door replacement, no more draughts, happy days!

If you're considering replacing your windows with uPVC panels, doing your research first is important. You can choose from different types of window panes, depending on your needs, and each type comes with its own set of benefits and drawbacks. Single-pane uPVC windows are made with high-quality materials and have the potential to last for many years without any damage. However, they may not be as energy-efficient as double pane windows or thermal break glass. Double-pane windows are great for energy efficiency because heat is dispersed more effectively through the panes. They also come with thermal break glass, which stops the windows from getting too hot in the summertime. If you're looking for a lasting, energy-efficient solution, then uPVC windows are a great choice!

If you're experiencing any damage or broken parts with your uPVC windows, it's important to call an expert. UPVC windows are delicate and can get damaged easily if not taken care of. By calling an expert, you'll be able to prevent any further damage and have the windows repaired in the most efficient way possible. Aside from window cleaning, it's also important to keep your windows clean. Dust, rain or snow can build up on the windows over time and cause them to become damaged. Regularly clean your windows with a window cleaning service to keep them looking their best.

Yes, uPVC windows are weatherproof. When installing windows, use a window sealant or protector to ensure that the windows remain weathertight for years.
