Windows In Listowel

Our replacement windows are sized to fit into existing openings. When you contact Clera Windows and Doors in Listowel, our professional technicians will engage you to measure the size of your current windows.

Careful and accurate measurements are critical because your replacement units are designed to fit securely inside the jambs that remain after your old sash is removed.

Our replacement windows are entirely made from vinyl, which helps to improve energy efficiency and provide superior resistance to the elements for maximum durability. Also, our vinyl replacement windows are low maintenance, and won’t require any painting except to change them to a different colour.

Our windows are available in any colour and style you want, from classic to contemporary. Clera’s window selection includes end vent sliders, double-hung windows, and awning windows, which can be customized to include any features you want.

Doors In Listowel

Clera’s replacement doors in Listowel can be used to reduce drafts while improving curb appeal.

Modern exterior doors offer a range of benefits that were previously not available. Today, obsolete solid wood entry doors have been largely replaced by vinyl, fibreglass, and steel doors, some of which are filled with foam insulation.

We have a range of high quality doors that have the same appearance as traditional timber versions, but deliver weather resistance, improved energy efficiency, and exceptional dimensional stability (ability to withstand cracking and warping).

When looking for a new entry door, you should consider getting a pre-hung unit or a door that comes installed in its frame, with the exterior trim, weatherstripping, and threshold attached. Many exterior doors are also fitted with sidelights that increase the side of the door’s rough opening, such that light and views remain available around the door itself.

At Clera, we offer a range of door styles to choose from, so you can find one that matches your exact design and functional needs.

Call Us Today

At Clera Windows and Doors in Listowel, we prioritize customer service – a value that has been recognized by HomeStars and Top Choice Awards. Our recognition by these bodies is due to our satisfied customers, who repeatedly recommend us to their friends, family and colleagues.

We personalize your design to your needs and manufacture the doors and windows as per your requests in our own factory. Our experienced installers then handle the installation process, and backup our service with a lifetime warranty that is unmatched in the industry.
