Window & Conservatory Installations

Insulating Windows Ltd

It’s now 5 weeks since my initial installation date, which was cancelled with zero notice.  They have taken over £1200 and show no signs of actually installing and haven’t even bothered to contact me.  Their initial excuse was supply issues, but this seems more to be about the company not paying their suppliers than an issue with manufacture or delivery.  Awful customer service.  Legal action seems the way to get my money back.

New kitchen window and door.

We are completely satisfied with the installation by Insulating Windows and our dealings with the company at each stage of the process.  There was no hard sell and the replacement windows and doors match the original windows like-for-like, but with significantly improved double glazing and insulation.  The two fitters who installed the windows were thoroughly professional, working quickly and cheerfully in at times challenging conditions, and adjusting their plans to cope with scaffolding erected for another job.  A minor problem with one glazed unit was quickly fixed.

Installation of Residence 7 uPVC replacement windows and doors

We've had the windows almost a year now and cannot fault them.  They have greatly improved the look of our home and made the property warmer and quieter.   Excellent service from the team with the installation being undertaken over 3 separate visits to suit building works I had ongoing at the same time.  Thanks to the team for the good work and great product.

Replacement glazing and doors

Excellent service from start to finish.  Competitive price.  Workmanship to the highest standard.  Product supplied excellent and robust.

Replace front door and panel.  Replaced blown pane of glass in window.

New front and back door.

Clean and tidy workmen and very satisfied with finished windows.  Did feel that the work could have been completed in two days rather than three.

Replacement of five windows.
