Made-to-measure uPVC, aluminium, sash and flush windows, surveyed and fitted by our own experienced team since 1987.
Replacing your windows is one of the best upgrades you can make to a home. The right windows keep the heat in, the noise out and intruders away, and they change how your house looks from the street.
Excellent Windows has installed windows since 1987, and today covers homes throughout Hampshire, Berkshire and Surrey. Our installers have between 20 and 38 years’ experience each and are trained to NVQ standards. We give honest advice and never use hard-sell tactics.
Every window is made to measure. We survey your openings with laser measurements, check the lintels and frame condition, and recommend the style and glazing that suits your property. That might be a straight swap of tired casements on a 1980s semi or period-correct flush sashes for a Victorian terrace in a conservation area.
Every installation is covered by our 10-year insurance-backed guarantee and registered with CERTASS for Building Regulations compliance.
What you get with Excellent Windows
Most homes in Hampshire and Berkshire suit more than one style. We’ll show you samples at your survey and explain the trade-offs in cost, looks and ventilation.
The most popular window style in the UK. Side- or top-hung sashes suit almost any property, from new-builds to 1930s semis. They’re cost-effective, open wide for ventilation and come in any colour we offer.
The sash sits flush with the outer frame, recreating the look of traditional timber casements. A good choice for cottages, character homes and anyone who wants a cleaner, less bulky frame. Available in our Residence 7 and Residence 9 ranges.
Vertical sliding sashes for Victorian, Edwardian and Georgian homes. They keep the original character of a period property while getting rid of draughts, rattles and rotting timber. Choose from uPVC and timber-alternative options with authentic period detailing.
These open inwards, either tilting at the top for secure ventilation or swinging fully open. That makes the outside glass easy to clean from indoors. They’re ideal for upstairs rooms, flats and wide openings, and can double as a fire escape route.
Slim frames, bigger glass area and a crisp modern finish. Aluminium suits contemporary homes, extensions and properties where you want the frame to almost disappear. It is very strong, won’t warp and comes powder-coated in a wide range of RAL colours.
Replace tired bay windows without losing their shape. We survey bays carefully, including the structural posts and roof, so your new windows fit accurately and last.
Whether you’re after classic charm, contemporary style or cutting-edge performance, we’ve got the perfect window for your home. Explore our collections below to find your ideal fit.
