🟧 Sarnia Windows
Sarnia Windows is a local Guernsey-based business specialising in window repairs, servicing, and glass replacement. We focus on practical solutions—repairing where possible, replacing where necessary, and always aiming to provide reliable, straightforward service.
Our Services
We replace worn or failed friction hinges on uPVC windows, restoring smooth opening and secure closing. Over time, hinges can stiffen, drop, or fail completely, causing draughts, poor sealing, and difficulty in use. We supply and fit the correct hinges for your window, ensuring proper alignment, improved insulation, and reliable day-to-day operation.
We repair and replace spiral balances in sash windows, allowing them to open and close smoothly again. When balances fail, windows can become heavy, drop suddenly, or refuse to stay open. We install the correct tensioned balances to suit your window, restoring safe movement and proper function without the need for full replacement.
We replace failed or misted double glazing units, restoring clarity and thermal performance. If your glass is fogged, broken, or no longer insulating properly, we can remove the old unit and fit a new one to match your existing frames. This is often a cost-effective alternative to replacing the entire window.
