Replacement windows are a great way to update the look of your home while increasing its curb appeal and value. Current replacement windows perform much better than older wood and single pane windows ever did. They are heat welded at the corners to form a structurally sound frame. The result is a strong, watertight and airtight window system. Vinyl windows installed by Jefnik Windows and Doors will never need sealing or painting since the vinyl is extremely durable and will withstand discoloration and fading.

Jefnik Windows and Doors is a local window and door company providing sales and installation services of new and replacement windows and doors for Mississauga, Oakville, Etobicoke, Toronto and the rest of the GTA. We have a wide selection of energy-star rated vinyl windows. At Jefnik Windows and Doors our goal is 100% customer satisfaction and complete peace of mind during your window installation project.

How to Tell if You Need New Windows

Difficulty Locking, Opening or Closing Windows
Opening and closing your windows shouldn't be part of your daily workout routine - they should open and close with ease. A proper functioning lock is an added seal against air escaping from your home, as well as providing additional security. Anything less could mean that it's time for them to be replaced.

Condensation Build up Between Glass Layers
Between the two panes of glass in double-glazed windows, there should be an airtight seal to reduce heat transfer. If this seal is broken, you'll get moisture build-up on the inside of the outside pane of glass because that has the coldest surface. A cracked seal is a sure sign that it's time to replace your windows.

You Hear a lot of Outside Noise
Do you really want to hear every single thing going on in your neighbourhood? Older windows do not provide very much sound insulation, so if you can hear your neighbour's car from way down the street, you might want to consider replacement windows to absorb those everyday sounds.

Window Frames Are Soft, Chipped or Water Damaged
Even high-quality window frames can rot and decay over time. Being exposed to moisture and dampness causes rot - and in some cases, mould can develop. Take a close look at your window frames and sills. If there are signs of decay or mould growth, it's time for replacement windows.

There's a Draft, Even When Your Windows Are Closed
Can you hear the wind whistling through your windows? Can you feel the cold air coming in around the frame? Or hold a tissue to the window frame and see if it quivers. If your windows are in really rough shape, you'll be able to see light coming through gaps in the frame. Drafty windows will definitely be more noticeable in the winter months when the cold air can be felt blowing into your home. This will have your furnace working overtime as it kicks in to keep the air inside your home at a comfortable temperature.
