We had two new Victorian-style wooden double-glazed sash and case windows made for our 1870s tenement flat. Jaymax removed and disposed of the inappropriate uPVC replacement windows that were previously there, installed the new windows and reinstated the original shutters. We chose Jaymax because they offered a superior product at a highly competitive cost. Whereas most new wooden sash and case windows rely on a single seal (brushes or plastic seals) their windows contain both, discreetly concealed so that the sash frames are visually nearly indistinguishable from Victorian originals. The double seal has significant benefits for draft sealing and noise reduction, especially important as our flat fronts directly to the street. We were also able to upgrade the bottom rails from softwood to hardwood, increasing the long-term durability of the windows at a cost that was still less than most other quotes. The design of the new windows is authentic, and closely matches the original style used in our block, and the standard of materials and craftsmanship is high. Installation was rapid and efficient, and the joiners who installed our windows were polite, friendly, highly capable, and went out of their way to ensure that they did a neat and thorough job. We were particularly pleased that they were able to reinstate and adjust the shutters so that they were fully functional again (they had previously been nailed shut), whereas other companies (including the most expensive) were reluctant to commit to doing this. Snagging (weights not perfectly balancing the upper sashes) was dealt with rapidly and effectively. My only minor quibble is that communications could have been more efficient and effective at times (I had to chase to get the initial quotation and it took some effort to finalise the installation date once the quote had been accepted). This was however more than outweighed by the quality of the product, the installation, and the friendly and trustworthy service. I would consequently strongly recommend Jaymax without hesitation.
