Dovista, Rationel’s agents in my area, set up the warranty repair quickly. The technician arrived ontime, he replaced a faulty part in a window and fixed a more complex problem with a door.

High quality windows that we’ve had in our house for a number of years now. I recently needed to contact customer services. They replied very quickly and were extremely helpful. I recommend them as a company.

Absolutely no interest in after sales

Absolutely no interest in after sales, unable to supply replacement door seals, frame beads and has no service department. Look elsewhere if your looking for value for money

Extremely helpful

I contacted the company with a query regarding spare keys for existing doors for which I had had great difficulty getting cut accurately. They were extremely prompt and helpful with their response and were able to sort out my problem perfectly.

Not good windows

We installed Rationel windows into our home through a local installer. Given the location of our home we also paid extra for high salt permeable paint. Disappointingly we have noticed fading on all windows. Dovista have explained this as usual fading but we dispute this and feel given the value of the product quality issues of this nature should not be occurring within 5 years of installation. We have found Dovista to be less than helpful with this issue but recognised that the issue was present as they resprayed one door. This has noweft us with one door a different colour to all others. For us Rationel windows are sold as a expensive but high performing product but the reality is they are not worth the money.

Worthless Weasel Word Warranty

As I planned to invest a significant amount of money (£30k+) in my property to replace the windows and doors I searched for a reputable company in the expectation it would be a quality product. After selecting Rationel, I noticed a crack at the edge of the door glazing unit after fitting and contacted them through their retailer. Imagine my dismay when I discovered I had purchased a Worthless Weasel Word Warranty: Rationel’s response:

“the crack in your glazing is not product defect and therefore not deemed to be a valid warranty claim. As per section 2 of our warranty terms and conditions:This Warranty only covers that DOVISTA UK double or triple glazed units shall remain free of particles of dust or of humidity in the unit cavity for ten (10) years in the case of windows, patio doors, sliding doors and casement doors and five (5) years in the case of flush and glazed entrance doors.Therefore any replacement glazing will be chargeable.”

To translate: if Rational supply cracked windows, the Warranty you paid for is worthless but you can pay them for another. It seems the economic downturn we find ourselves in has converted this one-time reputable company which previously backed their products with a solid Warranty (see other reviews to confirm this), into a company that can no longer be trusted. Use at your own risk.

The only choice for premium doors

I reached out to Rationel and was quickly directed to a local supplier named Goose Joinery. They provided a quote within 24 hours and scheduled a showroom visit for the next day. The showroom showcased a wide range of Rationel windows, and the team was incredibly helpful without being pushy. The doors I bought were delivered as promised, and the installers were courteous, tidy, and took the time to explain how everything worked before leaving. Definitely deserving of 5 stars!

At first I struggled to sort the spare parts I needed I for my windows. Then I called and spoke to Lesley Millar. Lesley, listened, helped me to get the info she needed and then provided the most efficient service. The parts are on their way. Outstanding customer service, efficiency with a dash of human kindness. Thank you, please give this girl a raise!

The house with the lovely windows

We installed Rationel Domus timber windows, patio doors and front door (22 items in total) throughout our house 15 years ago and they've been brilliant. Look fantastic, thermally really effective on a 170 year old property, and acoustically really great too. We haven't yet needed to decorate the main frames after all this time, only the sills, due to the factory finish.

They windows receive lots of compliments from the villagers too and the house is known locally as 'the one with the lovely windows'!

Transformation of a listed building.…

Our Rationel Formaplus guided casement Windows and entrance door were installed by Goose Joinery of Carterton, West Oxfordshire.
We were very pleased and impressed by the service from start to finish, and with the quality, functionality and appearance of the newly installed windows and door.
Our listed building has been transformed in terms of exterior appearance, internal noise reduction and heat retention by the Rationel products.
We were greatly assisted by Bob and his staff in liaising with the Council planning officer for relevant consents, the installation was prompt and professional, and various access issues to the property were overcome by the installers.
Throughout,we were kept informed of the progress of our order, and the entire project was completed in good time.
Would definitely recommend Rational products and Goose joinery.

I am deeply unimpressed by Rationel customer service here-or more accurately whether they want to have more of my money in exchange for spare parts. I have received no direct reply to two different contacts regarding spare parts I need. I cannot open my front door, despite the installer trying for over an hour and haven't been able to for over 3 weeks now. The lock has failed (the metal has sherred) and it has been over a week since they handed on the contact to the third party who installed the doors to sort out. Putting complaints online seems to work but is a rather unusual way of handling things. One would have thought sorting issues out privately would be better for your brand.

Rotting from the inside out - flawed design

We had Rationel widows specified for our new build in 2016. From the outset, water appeared on the inside. They sent out an engineer twice and eventually replaced one of the 8 large courtyard windows. The issue of water appearing on the inside never went away, and despite regular internal and external painting with the factory supplied paint, rot is now apparent at the base of 5 of the windows - this is from the inside not the outside! We are now faced with either a tricky repair (if possible) or replacing all of the windows / sliding doors (13m by ~2m worth) at considerable cost. If asked, I would recommend staying well clear of Rationel - their 5y warranty on wood windows is a clear indication of the little trust they have in their own product.

Great after sales service!

There was some water ingress between a double glazed glass window pane 5.5 years after installation. The After Sales team verified the problem and ordered a replacement glass under warranty within days of being notified of the issue. A quality after sales service from a quality manufacturer of windows!
