Be careful, the good reviews (from before December 2022) refer to the old business owner. In mid-December this changed and had to postpone existing dates. He simply didn't show up at the agreed appointment without canceling. He would have forgotten it. But he would come later on the same day. So keep waiting. Then I got a call saying he couldn't make it. Unfortunately very unreliable. It's a shame because we were very happy under the old managing director.

KFVG did a great job. They are super easy to reach, communicate clearly and promptly and are easy to deal with. I had to leave the house for a meeting when KFVG were supposed to clean the windows and we managed to make arrangements for them to get into the house and get the job done. I can recommend them without any hesitation.

We hired the company for the first time and are very satisfied. The friendly young man arrived punctually at the agreed time and had all the necessary work equipment with him. The work was carried out quickly and neatly. The price-performance ratio is absolutely appropriate. Gladly again!

(Translated by Google) Excellent window cleaning. Great value for money, even got a 30% discount for new customers! Very nice contact and competent specialist. We would be happy to use it again. (Original) Ausgezeichnete Fensterreinigung. Super Preis-Leistungs-Verhältnis, haben sogar 30% Neukundenrabatt bekommen! Sehr netter Kontakt und kompetente Fachkraft. Nehmen wir gerne wieder in Anspruch.

What great service! Very competent and friendly chaps who you can trust in your home. Also, the pricing is very reasonable. There is a bit of a wait to get an appointment as they are very busy but we have regular appointments booked and that works well.

Really great, quick service! A nice English as well!! Same day service and my windows sparkle!! He went over and above!! Super job plus very professional!!

If you need your windows clean, stop searching. You are on the right place this guy is just a pro and extremely cheap!!

Beste Fensterreinigung aktuell in Aachen. Zuverlässig und sehr freundlich. Preisermittlung sehr transparent durch Aufmaß der Fenster und des Wintergartens. Die Qualität der Arbeit war sehr gut - wir werden zu Stammkunden.

(Translated by Google) Very uncomplicated and quick appointment. Estimate on site and it was cleaned immediately. Windows and frames are clean and have no streaks, although some stubborn stains had to be fought. Top price-performance ratio! (Original) Sehr unkompliziert und schneller Termin. Kostenvoranschlag vor Ort und es wurde sofort gereinigt. Fenster und Rahmen sind sauber und haben keine Schlieren, obwohl teilweise hartnäckige Flecken bekämpft werden mussten. Top Preis- Leistungsverhältnis!

Zuverlässig und super freundlich! Ich lasse mein Schaufenster von KFVG reinigen und bin äußerst zufrieden!

Zwei Stunden gute und professionelle Arbeit für 15 F. Ich wurde sogar darauf hingewiesen, dass ich zu viel Fläche angegeben habe. Somit wurden die Leistungen zu einem günstigeren Preis erbracht. Einfach Top!

Ich war auf der Suche nach einem zuverlässigen Fensterputzer und wurde im Internet auf die Firma KFVG durch positive Bewertungen aufmerksam. Ich kann dies ohne Einschränkung bestätigen. Herr Khasib arbeitet sehr sauber, deckt alles weitläufig ab, so dass auch keine Wasserflecken auf Parkett etc. entstehen können. Er ist sehr gewissenhaft und auch einfühlsam und hat kein Problem damit, wenn z.B. ein Haken am Fenster nicht entfernt wird. Das haben wir schon anders erlebt. Auch nimmt er sich viel Zeit. Unsere Fenster strahlen, was sogar meinem Mann von der Straße aufgefallen war. Sie sind immer noch sauber und strahlen, obwohl es schon mehrmals geregnet hat und die Fenster sehr nass waren. Wir sind sehr froh, diese Firma gefunden zu haben. Wir können sie sehr empfehlen.

Unfortunately extremely unreliable! Today was the 4th appointment in 8 weeks, which was canceled at very short notice, just 3 hours in advance, even though we had spoken on the phone yesterday and he even wanted to come 2 hours earlier. It's extremely annoying when you clear over 20 window sills the evening before, tell the tenants in the house that someone is coming, the stairwell needs to be cleaned urgently and then no one comes. Unfortunately I cannot recommend this company! Reliability is key and I'm super disappointed! PS: The company appears to have been resold. The former owners, who had done their job very well in the past no longer exist. Maybe that explains a lot and the recessions here.. :(

Sehr freundlich und zuverlässig, haben sich viel Zeit für die Reinigung genommen und der Preis ist fair. Ergebnis auch gut, wenn auch nicht überall ganz perfekt (zT Wasserränder in den Ecken), was aber vermutlich auch daran lag, dass es zum Schluss schon dunkel und nicht mehr alles gut erkennbar war. Und ich hätte mit auch die Reinigung der Rahmen von außen gewünscht, das ist nicht überall erfolgt.

(Translated by Google) Commissioned the company for the first time. The young man was on time and had everything with him. The conservatory has never been so clean, we are thrilled!!!! Price performance is completely ok. (Original) Haben das Unternehmen zum ersten mal beauftragt. Der junge Mann war pünktlich und hatte alles dabei. So sauber war der Wintergarten noch nie, sind begeistert!!!! Preisleistung ist vollkommen ok.

Very good cooperation with KFVP! We were able to take advantage of the window and facade cleaning services. Particularly noteworthy is the uncomplicated and friendly contact with Mr. Khasib. All appointments were kept and additional services were announced and billed fairly in advance. Summary -> TOP satisfied, gladly again! Thanks.

Nice Window Cleaning Company. Very fast students!

Under the old managing director (until the end of 2022) I gave it 5 stars: thorough window cleaning and friendly service With the new managing director, agreements were not kept several times and he didn't come at all or came too late with very short-term cancellations...it's a shame. Since the actual work was good, 2 stars.
