Costello Windows Arvostelua 

My mam had 4 doors fitted 2 weeks ago all done in the horrible weather so they weren't the cleanest going in (though a canopy was used still dirty they are white doors). A black mark was made on a newly paint inside of the front door which she was told when she called up that she must have done this. The kitchen door doesn't shut properly you have to slam it. Someone came out last weekend to fix some of these issues but don't fix the kitchen door which also needed filling that wasn't door.
The person who installed the doors when leaving the first night was hitting off the new door while carrying stuff out.
Very unprofessional service.

This company is hands down the best. I have dealt with the entire time since moving here over 10 years ago. From my first contact just for information . All my questions were answered in a polite and concise way. They stayed in contact throughout the entire process just seeing if I had any other questions and even helpful hints to make sure things went smoothly on installation day. Its so refreshing to deal with a company who cares about their clients and it would appear we are not just a number. No pitches or upscale at all. That is very rare.

My installer James. You could not find a better representative for your company. He was on time, walked up thru the entire process and kept us updated along the way. He worked incredibly hard and it was lashing rain and to be honest I don't think he even took a lunch break he just kept working and I wish I could show you how great he was the door was fitted perfectly no gaps anywhere as opposed to our last door where you could feel the wind from the kitchen! That means huge savings on heat! James was kind, courteous, a perfectionist. I can't say just how good he was and his work speaks for himself.

I'll stop rambling but I would recommend this company higher than just a few stars as it was so beyond that. They have a life time customer in us and im hoping my 2 cousins that need new front and side doors listens to me and goes through this crowd.

Anyway thank you James for all the hard work you put in. I personally will be asking for him again when its time for windows and another side door.

My sincerest thank you to everyone. It's getting harderamd harder to find such an upstanding place of business like this.

Kind Regards,

We had a seamless experience with Costello. The sales call with Hayden, showroom with Justin, measurements with Derry, Brendan and Bruno who organized the fitting, and above all the fitters, Timmy and Michael - we couldn’t fault anything throughout the process. The lads are exceptionally hard workers and also super considerate, tidying after each fitting and clearly caring about how well done the job was. We had 9 windows and 3 doors, including removal of a large window and block wall to be replaced with a smart slide door. It was heavy work and they crushed it in the best way. Every step of the way made sure we were happy. Absolutely thrilled with the job, which was competitively priced too. Highly recommend Costello.

The installer, James, was very attentive and professional in his approach to installation our new door . He answered all our questions and offered good advice as regards maintenance. He did an excellent job. He also removed any debris that was left over from the work.
We are very happy.

Gerry and his co worker did a great job. Excellent workmanship, efficient and tidy.
Very pleased with the doors.

From the first point of contact Breda to the fitting James and Donal who came out to measure it was all seamless and an absolute pleasure.

Professional and reliable service from start to finish.
The job was completed to a high standard and everything was left clean and tidy

Very easy to order over the phone. I had done my homework so knew what door, colour and glass I wanted. Breda was on hand to answer any other questions I had. Brendan came and measured my door a few weeks after payment. James came and fitted my door. An absolute gentleman very helpful did a fantastic job fitting the door. Everything left nice and clean! Thanks everyone ☺️

Really happy with the service provided
The installation team were excellent
Very thorough and efficient
I’d definitely recommend them

Liam, Willie and the other chap that I can't remember his name were fantastic. The doors and windows are of excellent quality. I would highly recommend this company.

From the first point of contact the service was excellent. My windows were delivered when they said they would be. The fitters were so professional in their workmanship to their meticulous finish . Couldnt speak highly enough of them . Well done

James put in the door very well. I am very pleased with it. One small issue - a small bit of skirting board looks loose. Apart from that the work was excellent and James was very polite and professional

Fabio & his colleague fitted my beautiful door last week. They were very clean & quick in fitting it. They sealed it very well. I had an issue with the lock (my fault) & their serviceman came out this morning to recitfy it. Couldn't rate them enough. Very good service & aftersales.

I recently had the pleasure of working with Costello Windows, and I couldn't be happier with the results! From start to finish, the service was outstanding. The team was professional, knowledgeable, and attentive to my needs.

A special shoutout to James, the fitter, who did an exceptional job installing my new door.His attention to detail and craftsmanship were impressive, and he ensured everything was perfect before leaving. It’s clear he takes pride in his work, and it made all the difference.

Thank you, Costello Windows, and especially James, for transforming my home with such beautiful door I highly recommend them to anyone looking for quality service!

James from Costello Windows installed a new door for us. Very professional, had the whole thing done by himself on the day. New door is great, no issues at all. Would definitely recommended/use again.

Had the lads from Costello windows they done a good job im happy with it and they cleaned up well after the job was done would highly reccomend them

Very happy with the installation.Pedro and his colleague were good to deal with.

We are delighted with out windows and door. The whole process was very smooth. Willy and George were our installers and they were very good. Would recommend.

The installation team of Gerry & Jack were fantastic. Keen eye for the details in an old stone cottage that doesn’t have a square or true angle in it. The finish was extremely well done. We did have to wait for the doors longer than we were first quoted, but the sales team did say the combination of finishes we were looking for would increase the production time. Overall we were more than happy.

Found Costello windows very easy to deal with. Breda in sales was excellent and very responsive. Our fitter too did a great job. Very happy with it. Would definetly recommend.
