We are very satisfied with the quality of the product and the workmanship. The team of fitters arrived promptly and took time to ensure that our decor and furnishings were protected. Their work is excellent, the finishing on the interior windows is very neat and the overall look of the windows is pleasing. There were a couple of small areas of damage to concrete outside; these were mended within 10 days, no fuss. This was a good experience from beginning to end, the office staff were helpful, surveyor pleasant and informative, and fitters efficient and cheerful. Paperwork completed timeously with guarantee sent out in a couple of weeks. On our expereince, we can recommend CSJ.
