Rationel レビュー 

My experience of Rationel / Dovista, having had windows and doors installed five years ago, is that product quality is good, installation and fitting is excellent, and after-sales service is very good when it is needed. However, Rationel / Dovista's sales process is inflexible, not customer friendly and totally focussed on their internal procedures. The Operations 'Manager' in Edenderry could certainly benefit from some customer service training. Rationel / Dovista expect full payment three days before installation, leaving the customer with no leverage or comeback in the event of an unsatisfactory installation. Installation of a door was cancelled without notification because I withheld 10% of the cost pending a satisfactory installation. I am still awaiting a rescheduled installation date. This is not customer focussed organisation, and I suggest avoiding them and going to a company where your business is valued. Ciarán

I contacted rationel windows ireland on July 2 2026 by phone. A sales rep was to respond. Understanding Business in that area is busy I left it for a couple of weeks. I made contact again to be told that I would be contacted, but no such joy. It is now July 29. I emailed last week, 3 people including one of the directors in Cork office and no response. That is my experience with rationel. Who needs that sort of service when retrofitting 12 windows and a sliding door?

Spent thousands with this company on our windows and doors for our new home and have been treated terrible. Dealt with the manager in Galway office who is yet to return any of our calls and has blocked my husbands number, real good customer service. They installed the wrong front door on our house and assured us they would replace it and never did not only that but it’s damaged so on our brand new forever home after spending thousands with this company we are left with the wrong front door. After our window cleaner had been he told us a lot of our windows need sealing and haven’t been done properly. We have tried to contact rational a number of times no response. He should not be in a management position. We are extremely upset over this. We have had lots of interest from people about our windows when they pass our house but when they ask we tell them not to go near rational. Save yourself money and hardship don’t go near them

Poor customer service and middle of the market product.
We had a service call for wind noise on a large fixed window. Technician call out (very nice guy) and replaced external beading. He identified he needed to call back for glass compression as the adhesive holding the glass to the frame moved during manufacture (Service date 13 March 2026). He advised that the call back would be arranged by him and the office. We heard nothing and I rang on the 29th June spoke to Maria who was pretty rude but assured me I would get a call back later that day. Its now the 13th July after leaving messages I finally got through and Maria who was again pretty rude and couldn't give me a date for repair. Extremely disappointing for the supposed top of the range window manufacturer.
We paid out close on €40k for windows and doors with rationel between 2020 & 2021. The price does not reflect the quality of windows. 100% I would not use them again.

Rationel supplied and installed French (Casement) Doors in my home. After a few days the wind caught the door and the lever arm broke damaging and breaking off the wood as it detached. It was not a particularly windy day and the force was not excessive. It became apparent that the wood of the door frame was very low quality. This is despite the doors costing Euro 4800. I had been informed that they were top quality which is why I paid this price. Eleven days ago I contacted the sales rep James Devlin, who sold me the doors and he informed me that it was nothing to do with him but that he would submit a service call request. I have since heard nothing. Yesterday, I telephoned Maria at their service department twice and no answer. I left 2 voice messages and still no response. I will never do business with this company again and the quality of their product and after sales service is awful.

Very unhappy .
No reactivity .
They came to install a big sliding window .
I got the old doors and windows removed the day before as requested .

They came and said they could not install the sliding window because there was not a base of concrete to support the window . I managed to organise that done on the same day .
But they didn't react and decided it was ok to let me have an open room on the outside for a week .
And the usual " he is on the meeting and call you after " and of course he does not call back ..
I have a child with Down Syndrome and can't have an open room on the outside .
No response , 0 communication , and no empathy to a difficult situation which arose because they didn't communicate .
Avoid them . They are extremely expensive and their customer service is 0 ..
I'll spread the word ..
starting here .

We were there in person in Galway to consult.... man was very nice & helpful, but we NEVER heard from him again. We called him several times, he kept putting us off.....until today, months later, no feedback, very unprofessional & dubious.
(The same thing happened with NorDan, it's next door, I just can't believe how unprofessional both companies are)

5 weeks late on delivery at install time. (Nov 2018). Main pain installed with busted seal and scratched. Its replacement also delivered scratched. Had to chase for two months to get gubbins to fill frame mounting screw holes. 5 years later a pain shatters for no obvious reason. Contact them and they won’t come out to investigate. Just blanket glass not covered under warranty. Then they ghost my emails. I write a review incorrectly on Rationel UK, they instantly contact me and them a different entity. They contact me and I provide clear evidence of a poorly fitting window opening that’s allowing water get in on top of it (the same one that broke for no reason) and I am ghosted again. A pretty poor experience to which they’ll probably not even respond to here and if they do, it will be to say ‘reach out to us’ despite them not now answering three different email threads.

We recently replaced all our doors and windows using this company. The service and quality of fitting was excellent. We are very happy with the finished product which is of high quality than most we viewed. There were some hiccups but once their customer service manager called out these were resolved very quickly and to our complete satisfaction. Highly recommended.
