Windows In Mount Forest

Whether remodelling, building a new home or adding to your existing home, our Mount Forest clients know that getting the right doors and windows can minimize heat loss and costly drafts.

At Clera Windows and Doors in Mount Forest, we manufacture and carry a wide range of vinyl windows, including single/double slider tilts, single/double-hung windows, casements, and awnings. Additionally, all our windows come with Low-E glass, and can be customized to your exact needs.

With Clera Windows and Doors in Mount Forest, replacing your windows is a simple three-step process:

  • First, you choose your style from an assortment of maintenance-free vinyl windows, including modern and classic designs or double hung and specialty shapes.
  • Second, you choose the glass you want. However, all our vinyl windows are engineered with Envirosealed glass to optimize energy efficiency. So, you only need to put other considerations into account, like security and privacy, and perhaps how much energy savings you want to achieve.
  • Third, you choose the colour of your custom windows to match your room decor. Most of our clients find our standard colour palette to be satisfactory. But to give you exactly what you want, we can invite you to our in-house custom paint facility. We use state-of-the-art colour retention technology to ensure that your colours won’t fade away.
