Very Professional, timely and cost effective service.
Proper quotation method, consultation and ordering process.
Very efficient fitting and finish to the work. 5 stars all round.

Costello windows were fantastic to deal with. From dealing with Eddie who organised the sales piece of the process to brendan in delivery they were so helpful and professional. The fitting of 10 windows and 1 door was for my elderly parents so it was important to me that the job was done right ✅️
To the two guys fitting Timmy Murphy and Michael O Connor thanks so much for doing an amazing job. Ye were a pleasure to deal with.

Installed a Palladio door for us and really delighted with the work. Everything about the door is well done, great workmanship and top quality materials used in the door itself.

Very helpful with arranging a replacement door due to a fault. Door fitters completed the replacement door fitting very efficiently. Overall, very pleased and happy with the service provided.

Ordered a composite half door with two colours exterior was Chardwell green and interior was cream. The finish to this project was excellent. The service was prompt and the only waiting time was the production of the door extremely happy with the outcome, many thanks to Costelloe windows.

Great experience from start to finish by Costello Windows with major refit. From initial contact through measurement & final fitting, everything occurred within specified timeframes. Installation was beyond expectations- Jerry & Jack did a fantastic job. Highly recommended all round (24 windows, 3 doors)

I got a new front door fitted today by Costello Windows, and I’m absolutely delighted with it! From start to finish, the service was fantastic. James, the fitter, was extremely professional, friendly, and did an excellent job. The attention to detail was second to none. I would highly recommend Costello Windows.

Had a patio door replaced with french doors by Costello windows….they done a superb job. Very professional from day 1 a fantastic service was offered and great workmanship provided by James! 10/10!

I had a great after sale service with Costello windows. They came and fixed the lock on the door as it was getting stuck trying to open it. I was met with a very kind man, he arrived punctual and was very helpful and fixed the problem immediately. I would highly recommend this company to anyone changing their doors or windows.

Very happy with the service and advice for my new front door . I would happily recommend Costello Windows.

The installation team for Costello Windows were first class, very friendly and carry out their work quickly and efficiently. Im very happy with the end result of the work carried out

Recently had a front door fitted by Costello Windows and couldn’t be happier with the fit. The installation was done when they said it would with an accurate lead time and the actually fitting was second to none. The day it was replaced wasn’t good weather wise but the job was still done and the sealing was done during dry spells. The area was left hoovered and cleaned up, very professional finish. Again thanks very much for the service

I had to have a window replaced and whilst I had to wait a while for it as it was manufactured by another company, Amelie kept in constant touch with updates. Today the amazing John and his team arrived to remove the old one & fit the new one. The windows were extremely heavy and difficult to manoeuvre but it was completed without a hitch. As always exceptional workmanship from the nicest crew.

Since we had our windows installed in January 2022, we have had an ongoing problem with the metal fittings on the window frames: they have rusted badly. This affects in particular the small upper windows which are opened regularly.

Just to say that the follow-up service from Costellos has been excellent. They have recently replaced the rusty fittings and the fitter, John O'Sullivan, was very thorough, oiled and serviced all the windows and gave us good advice on how to maintain them in future.

Costello window and door repairs are so helpful, obliging and professional. from the moment you pick up the phone, Amelia is so thoughtful and caring. She will really help out with window repairs and give accurate details on when call out will be. The company is very prompt with dealing with any repairs. John was also so helpful on call out. I am so delighted with the windows that they repaired in my house. They have done a brilliant and professional job. The price was excellent. I would highly recommend Costellos. Thank you Amelia and John.

Ordered 7 windows from costellos found them very easy to deal with and very price competitive. Derry measured up and called after job was complete to check quality, couldn't be nicer. The lads installing willie and his helper were very nice and did a great job. It was a long day for them but they installed it all in 1 day. Would highly recommend!
