Costello Windows Arvostelua 

I, was given a 6 week time to get my windows installed, after repeatedly been given new dates i got them installed. Never again.

Really happy with my new front door. Seamless procedure from initial inquiry to the last phase of fitting door. Great value. James, the fitter, did a fantastic neat job and was a very nice gentleman. He vacuumed my hall and swept my front step! You wouldn't believe I had a new door fitted. Thanks to all at Costello Windows.

It was a pleasure to work with Costello Windows and we received an excellent service from start to finish. We are delighted with the exceptional quality of our new front door and glazing. The workmen were highly skilled, friendly and installed the door & glazing to a high standard finish. Good housekeeping and they left the house spotlessly clean. I would highly recommend Costello Windows to family & friends.

I had a great experience with Costello Windows, and I would highly recommend them. We had all the windows in the house changed, and also 2 PVC double doors installed. The people we dealt with in the office were very accommodating and helpful, also the guys who installed the window were very efficient. We will definitely be using Costello windows again.

We recently had our windows fitted by Costello Windows and couldn’t be happier with the result. Gerry and Jack were excellent — professional, efficient, and really went above and beyond. They worked quickly, installed everything perfectly, and even took the initiative to fill in small cracks that could have caused problems later. Their attention to detail and helpful attitude made the whole experience stress-free. I’d happily recommend Costello Windows to anyone and would definitely have them back again in the future.

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 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.

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
