Exterior door replacement in Sun Prarie 

If you notice any of these signs about your exterior door, it may be time for a replacement. Doing so will save you more in the long term.

  1. The door becomes difficult to operate
    A door that has trouble opening, closing or locking properly may need to be replaced. This may show that your door is simply too old or needs to be realigned.
  2. Cracks or holes in the door
    An exterior door that is breached by cracks or holes are immediate grounds for a replacement. The door will provide little to no protection from the elements and its integrity will rapidly diminish.
  3. Visible gaps or holes around the door
    Even if the door itself is sound, it won’t do much against the outside world if there are holes or gaps around the door frame. A contractor may be able to realign your door to close those gaps, but some cases may require you to replace the entire frame.
  4. Drafts and uncomfortable temperatures
    Interior drafts while the door is closed can be caused by small gaps in the door or the frame. This can lead to significant increases in energy bills and rapid changes to your home’s temperature.
  5. Moisture buildup
    Water buildup around your door can also be a sign of gaps in the frame. Make sure to call a contractor to reset your door or replace your frame to keep your home nice and dry.
  6. Outdated design
    Your patio door may simply not match the color scheme or style of the rest of your home. Browse through Infinity’s trusted brands to find a new door with the perfect color and style you’re looking for.
