Perfect professionalism from first point of contact to cleaning up after work. Very consistent and thorough in communication. Prices are upfront and fair and most importantly - finished product is perfect. So happy I found them on Checkatrade and decided to solicit a quotation from them. Local London shops and nationwide leaders didn't measure up!
Customer, Dulwich, London
Three workmen carried the work out in just two days, friendly hard working.Douglas and Alastair very friendly and helpful salesmen - never pushy. Great family business - reliable and efficient from start to end.
Mr Jeeves, Croydon
We had a great experience working with Alaskan Windows. Great communication and friendly staff. The work was completed in a timeframe that suited us and to a high standard. No complaints and would recommend to anyone. Thank you.
Claire Archer
A very good experience from start to finish. Replacement of two old windows on 3rd floor of block of flats required advanced liaison with Block Management and scaffolders. The fitting day went well with all mess cleared away and finish well within the time quoted. Will definitely consider involving Alaskan in replacing two large living area windows at the property.
Jeremy Noble
Professionally run company, quality products, very high quality installation and also a competitive price. I have used them on more than one occasion and happily recommended them to friends and family. I would certainly use Alaskan Windows again in the future for all double glazing requirements.
Stuart Cooke
Absolutely thrilled that we chose Alaskan Windows for our window replacement! The sales team were fantastic—so patient and clear in explaining everything, especially since we didn’t know much about the different types of windows. No pushy sales tactics at all, and the price was surprisingly competitive. Huge thanks to the installation team—you did an amazing job! And a big shout-out to the admin team for making the payment process, documentation, and warranty follow-up effortless. Our home feels so much warmer now, and it looks incredible with the new windows!
Albert Salihu
We have been so pleased with Alaskan Windows. From start to finish they have kept us informed, been clear on everything, kept all appointments, worked tidily and respected the property. They are superb and hold the values needed for customers. We have no hesitation in recommending this company and would definitely use them again. Thank you.
