Whether through your window or door, a water leak can cause severe damage to the home. Water intrusion leads to mould growth and rot, which can damage walls and floors ceilings and cause health and structural damage. So if your house window leaks when it rains, make sure to take immediate action and stop the leak before it evolves into something more serious.

A common myth is that water damage only happens in older homes. However, old age is not the only cause of door or window leaking. To help homeowners learn more about this problem, we prepared a short guide about door and window leaks. Here is everything you should know about the causes and solutions of common water infiltration into the home:

WHY IS WATER LEAKING THROUGH MY WINDOWS AND DOORS?

When water starts leaking through windows and doors, the first question that pops into everybody’s minds is why? Why is water leaking through here? To find the source of the problem, you first have to know all possible scenarios. So here are the most common reasons why your windows and doors are causing you water issues:

DAMAGES TO WINDOW SEALANT.

A proper window sealant is the best defence for outside air and water. If it’s damaged or missing, snow and rain will have no problem getting inside. As soon as you notice that the caulk is damaged or missing, schedule a door or window caulking repair or replacement. It will not only fix the leaks, but it will also reduce your energy spending, especially during harsh weather.

OLD WINDOWS AND DOORS.

Even though old age is not the only reason for water leaks, it’s still one of the most common ones. The fact is, materials lose functionality over time. If your window or door has passed its lifespan, it’s time for a change! Plus, just like a new sealant, quality replacement windows or doors can also reduce energy bills.

INSTALLATION MISTAKES.

Sadly, there are some unprofessional companies that offer amateur services for a low price. This can result in many mistakes, whether installing windows, doors, or sealants. Wrongly installed window flashing, windows and doors, as well as an incorrect door or window size, will lead to leaks. It is best to work with certified and experienced contractors.

POOR HOUSE DESIGN.

If your windows and exterior door are professionally installed and made from quality materials, your leaks could result from poor house design. The most common scenarios are lack of overhands and bad angles. To solve the first issue, install quality overhands. For the second one, you have to find a smart solution and redirect fascia boards, gutters, and window sills further from the window instead of toward it.

DROPLETS ON WINDOW/DOOR GLASS.

You may notice a water leak that occurs between the glass panes. This happens when the sealant between the glass and the window/door frame gets damaged.

SIGNS OF WATER INFILTRATION PROBLEM.

Water infiltration through small gaps and cracks is harder to notice and often remains hidden for a long time before discovered, as water damages start to appear. At this stage, the damage to your property may already be extensive damage that requires some renovation work and your insurance involvement.

Besides water dripping from your window and door, here are some other signs that will help you determine whether outside water poses a threat to your home:

· Mould and fungi

· Swollen floors and walls

· Peeling paint

· Odd smells and noises

· Stains and discoloration

· Saggy drywalls

· High energy bills

· High humidity

· Decaying window/door materials

· Loss of soundproofing quality

HOW TO DETECT THE CAUSES OF LEAKY WINDOWS?

Now that you know all the causes of leaking windows, it’s time to detect which applies to your situation. Here are some of the steps you should take to find the source of water infiltration in your house. 

First, go around the windows and doors and inspect each area. Start with the most obvious questions like: do I have an overhang, is my fascia directing water toward the window, is my window AC leaking, etc.? If the issue is more complicated and more difficult to pinpoint, you have to start inspecting the infiltration source through doors and windows.

Start with the sealant as it’s easier to spot broken or missing caulking—Examine the glass seal as well as the window seal. Then, look around the window. If water is leaking from the top of the window frame or on the wall above the window, you might have a roof or wall leak. If the water is leaking from the bottom frame corner or the spot between the glass and the sill, you might have broken glazing or caulking.

Detecting the issue might be more complicated in some situations. To get a correct diagnosis, it’s best to consult with window companies, of which many offer free quotes and consultations.

HOW TO STOP WATER INFILTRATION THROUGH WINDOWS AND DOORS?

 

The solution to the problem depends on the cause of the leak. Once you find the reason, whether by yourself or with an inspector’s help, it’s time to take action!

Replace the caulking if it’s damaged beyond saving. This time, choose a caulking product that is of higher quality, durable, and long-lasting. Using the services of a professional caulking company in your area is recommended to ensure that your window sealants are sealed correctly and will last for ten years or more. Professional caulking companies have access to commercial-grade caulking of superior quality and will include a warranty.

If the reason for your leak is more complicated, replace the windows or doors. Sometimes, it’s the only solution, especially with old materials that passed their lifespans long ago. The solution doesn’t always have to be complicated and costly so before you opt for replacement windows, make sure to inspect all the smaller issues. For example, check your weep holes to make sure they are not clogged.

Having this in mind, the smartest choice you can make is to call an inspector. Working with a professional ensures results as you won’t have to worry about making a mistake, whether for the cause of the leak or the solution.
