FAQs
Is It Good To Invest in Energy Efficient Windows?
With the highly competitive real estate market in GTA, any investment that can potentially add value to your home is worth it. Energy efficient windows are always considered a major upgrade and definitely will add substantial value to your property.
The energy efficient windows are no longer eligible for Ontario Energy Rebate Program, GreenON. However, they still have proven to be able to reduce your energy bills and HVAC spent significantly. They are designed for climate control and lower heat losses, thus preventing drafts, breakages and air leakage. With these windows you will never feel the harsh winters or the summer heat in Port Perry.
Why Vinyl Windows Are Your Number 1 Choice for Window Replacement in Port Perry?
Vinyl windows are a perfect choice for your homes in Port Perry. They are extremely energy efficient and have an air-tight seal between the glass and the frame. Not only are they economical but are aesthetically pleasing and allow you to choose between an array of colours, or paint over white vinyl windows to get the perfect style of windows for your home.
