Doors Weston Downs & Surrounding Areas

Finding the right replacement entry door or patio door can help to improve the security and energy efficiency of your home. We have a wide selection of French doors, sliding patio doors, and storm doors, among others, that have been designed, fabricated, and tested in our factories to ensure that they are strong and sturdy enough to withstand continuous episodes of the harshest weather in Weston Downs.

Our doors come fitted with tempered glass as the standard because it is several times stronger than ordinary float glass. It is extremely resistant to impact and reduces the risk of break-ins through your garden or patio door. When the glass breaks, it shatters into tiny pebble-like pieces with no sharp edges, so it can’t harm you or your family.

We also offer the option of laminated glass, which is a blend of two or more sheets or glass with at least one interlayer of PVB plastic or resin. Laminated glass does not shatter like tempered glass when it breaks. Instead, the interlayer holds the glass fragments together as it continues to provide a barrier to entry. Besides its great security features, laminated glass is also a great noise reduction barrier, plus it blocks up to 99 percent of harmful UV radiation. This is vital when looking for peace and quiet on your patio, with minimal damage to the furniture from the sun.

We are proud to be recognized as a leader in the industry, a feat that we have achieved through the consistent delivery of quality products and commitment to customer satisfaction. We understand the value of having a skilled and dedicated team, and every installation comes with a lifetime warranty just for your peace of mind. If you are thinking about replacing your home or office windows in Weston Downs, contact Clera today to get the process started.
