" Thank you for completing this highly technical and major job to such an exacting standard. We particularly appreciate the aftercare too. Coming such a long distance to check and maintain means that you have high standards. The electronic openings work smoothly. There is no condensation at all. You really know and care about what you are doing. Further you took such care of the property and never left any mess at all. All in all everything you fitted was a premium product and the way the team conducted themselves and did their jobs would be hard to better. "
