My experience with my order

Hello,
Just ordered two beautiful doors from Klarvindu in Norway.
I must admit up to now the customer support I received in clearing up a small issue that was caused by a third party during the payment procedure was so professionally and fastly solved ,it gave me the customer the feeling of relaxation and comfort .Klarvindu fixed this issue easily and the reason I purchased from Klarvindu is because my son bought two times two large orders and he is so pleased with the performance of the products ,I too have seen his windows and they are very well made ,you can see and feel the quality.
So my next order I will be ordering 10 large windows in the coming months and it will be a pleasure to choose Klarvindu again .
Shaun ,very happy 😊.

I love the product

I love the product, but service is extremely poor.

I am very sad to write this, because klar has the best product in the market, but sadly they are very hard to work with.
they did not fulfill initial timelines, and only delivered under a lot of pressure from my end, installation was chaotic and the repairs needed after istalatio took over 3 months to be done.

hope they fix these issues

Klar delivers good windows

The windows that I received from Klar are rock solid and very well made. All parts appear to be very strong and over-dimensioned- There are absolutely no jiggling or undefined movements. I am very happy with the windows from Klar, and I will buy from them again soon. However, the delivery was delayed for several weeks. Fortunately, it arrived the day before the installer was to embark on another project, which would have pushed our project into 2026. Luckily Klar did a good job issuing information about the progress. In conclusion, I am very happy with the windows that I received, and I recommend buying windows from Klar (if you are not under too much time pressure).

Dear klar

Dear klar

I would like to kindly suggest that you include clear pictures and detailed size information of the windows — both with and without frames — shown separately on your website or product listings. This would help avoid confusion for customers when placing orders.

I recently ordered a window without a frame, but the one I received came with a frame and unfortunately did not fit. It could not be refunded, which resulted in a loss for me. Providing separate and clearly labeled images would make it much easier for customers to choose the correct product.

Thank you for your understanding and for considering this feedback.

Best regards,
Tek

Dear Tek

Thank you for your input.

On our page the products are clearly shown with a frame, and all product we sell are also with a frame included.

We have a measuring guide online, which shows how to take the correct measurements step-by-step, which also relates to the frame.

I'm sorry to hear there has been some misunderstanding, and that you didn't get the window you though you have ordered. I hope that you will be able to use the window somehow anyway.

Best regards

I was told more then a week ago that my order was on its way, great I thought I’m going to get it on my promised delivery week. Last week on received this Email asking me what I thought, my reply is simple. You told me I would get a call from the company chosen to deliver my order I’m still waiting. I have no contact to this delivery company. If it’s like the last time it will just turn up. Which is no good to me as I live in a rural area where I wil probably find the guy delivering my windows will refuse to drive down my lane, not a happy customer..

Hi John

I'm sorry to hear, if there has been any issue with your delivery. I can see you got an update from our customer support yesterday, and I feel confident that everything has worked as it should from there.

I hope that once you have received your order, it might be worth more than just the 1 star.

Very poor customer services

Very poor customer services - I received an incomplete and damaged order, contacted Klar many times about this, however, they are either non-responsive or send holding responses such as "i am still waiting for an answer".

I'm now in the first stages of legal action against them.

This is particularly disappointing, I have spent about £10,000 with Klar to date and the windows themselves have been good quality until the issue with my last order.

Hi Matthew,

Thank you for your feedback. I want to sincerely apologize for the delayed response to your claim. The delay is due to a vacation period during which our production team has been away. We're now officially back and reviewing all cases. Please rest assured that we’re taking your case seriously and will get back to you very soon with a response.

Kind regards,

awful experience

awful experience
the manager made a size mistake in my order
agreed color option was finally rejected
time delay 1.5 months
ordered on the week 17 2025, delivery was agreed on week 26 2025 latest, now they announced that beginning / middle of august
so, 3.5 months since the order date if they still deliver
do not recommend because of the total brainf-k this organization provides

Hi Aleksander,

Thank you for your feedback. I’m truly sorry about the experience you’ve had. It was an unfortunate mistake that your order was cancelled, which led to the delay.

I want to assure you that this was a one-off incident. This is not something that normally happens, and it will not happen again should you choose to place your trust in us once more.

We look forward to delivering your products and are confident that you’ll be very satisfied with their quality.

Please don’t hesitate to reach out if you have any further questions.

Kind regards,
Klar🪟

Very good service.

Very good service. I was particularly happy about your representative's offer to send me an email confirming the details of your bank in Lithuania. And your IT system made sure he had my email address at hand without me telling him (nice detail!).

The one thing I am slightly unhappy about, is that your system never "warned" me (as far as I can remember) that the bank transfer was supposed to go to a non-Norwegian bank (I only became aware of this AFTER the order was placed).

This made me wonder if perhaps your system had been hacked, and someone was attempting to fool me into sending the money (just over 100k) to another entity.
