  • 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.

    Replaced two wooden sash windows with PVC windows. Agreed a very reasonable rate compared to after quotes. Time schedule given was adhered to. Feedback given by their office staff whole way through process. Nice guys came to fit windows. They were efficient and left no mess at all!

  • AW installed secondary glazing for my box sash front windows, to schedule and on budget. The product uses acoustic glass and works very well to deaden noise from a busy road; the latch is simple to operate so that the front windows can be opened when required; and it's unobtrusive inside and out. They gave me a six week lead-in time and kept me informed by e-mail. The installers arrived on the day on time at 8 a.m. and completed the work in 90 minutes. Service was efficient and professional throughout from the first meeting with Doug the sales rep through to the installation. I didn't obtain alternative quotes but theirs seemed good value and matched my expectations. Overall it has been a smooth and stress-free experience and I would not hasten to recommend this excellent south-west London firm

    Mr Wright, London
  • Happy to recommend Alaskan to anyone looking to replace windows or for out a home - they’ve done a great job of replacing our 100yo original sash windows with a very elegant set of uPvc sash units. We were recommended Alaskan in the first place and they’ve been a pleasure to deal with. Michael firstly, with his understanding approach as we were looking at options. Nikki in the office who was always prompt to reply to our questions - and we had a few! And then Tony, who did a brilliant job with the install and finish. Very pleased with the Alaskan team, their products and service and have already recommended to neighbours.
