Windows protect us from bad weather while also giving us the chance to witness wonderful outside views. Unfortunately, with time they wear and tear, making our lives more difficult and filled with worries. On top of everything, we usually don’t see the consequences of common window problems until they appear on a larger scale.

Why do windows need to be replaced? Here are the 5 common window problems which most often than not signify that you need a window replacement:


We love windows and doors. They come in all shapes, colors, and sizes. But sometimes beauty turns into rage and usually, it’s when they start to become drafty. Apart from damaging your comfort, draftiness damages your electrical bills.

The more outside air windows let through, the more often we will turn on our HVAC’s and furnaces. New windows don’t cause such problems. In fact, a new vinyl framed window can cut 15% of energy spending.


Nobody likes to put towels and buckets beneath the window every time it starts raining. It’s one of the most annoying things that can happen in your home and one of the 5 most common window issues.

Instead of purchasing towels, opt for free consultations and find out your initial problem. Some window leaks require full replacement, others only retrofit. In any case, the problem won’t get fixed until you properly address it.


First draftiness appears than leaks, and finally, rot comes along. It doesn’t look well for your windows and it won’t disappear on its own. Luckily, there is a simple DIY method for rot removal. Here is what you should do:

  • Take a sharp tool and fully remove the rot inside the frame
  • Make sure you don’t leave any rot behind
  • Remove paint with scraper or sandpaperApply 4-6 coats of wood restorer with a brush
  • Wait 2 hours, apply a bonding agent
  • Apply epoxy to fill out the missing area
  • Shape with a putty knife to get the ideal surface


Apart from being scratch-less and energy-efficient, windows should also be operated with ease. Having windows that get stuck while you try to open or close them is never a good sign.

Sometimes the problem can be solved with lubrication, other times you need to replace them. In any case, windows that are difficult to open are also bad for your security. Intruders will have a much easier time getting in if your windows and doors are loose.


There are three types of condensation: Interior, Exterior are the one that occurs between glass panes. The exterior isn’t harmful. In fact, it’s a sign that your windows are working properly. It’s the result of a natural process that happens due to outside temperature changes.

On the other hand, the other two may be signs of window replacement. Interior may be occurring because high humidity levels in the room, but if not fixed on time, mold growth and rot can start to appear in your home.

Condensation between glass panes either means that the gas inside has started to leak, the glass got a scratch and lets air inside or that your frame and sash are damaged. Schedule a free consultation to find out what’s wrong with your windows.
