Caulking is the material used to line small gaps or spaces between two materials. It’s used on walls between drywall and crown molding, as well as on things like sinks when they are installed on countertops.

Caulk fits in seams to help prevent water leaking into spaces like floors or under toilets. It stops mold that leads to rot that can damage a house.

Windows use caulking to fill the space between the window frame and the home’s exterior. Without caulk, air, water and small debris would be able to get inside and negate the purpose of having a window in the first place!

Caulking is one of the small details that holds a house together. It’s made of a variety of materials, mainly silicone, rubber, latex or polyurethane.

Caulking, like most things, doesn’t last forever. Depending where the caulk is located, it can take a real beating. Exterior caulking protects houses from rain, snow, the sun and other natural forces every day.

Over time, it will start to harden, crack and eventually break. On a lot of older homes, it’s easy to see gaps in caulk lines where a large chunk has gotten too hard and fallen out. Window caulking needs special attention from homeowners because it can become displaced from opening and closing windows.

A home’s exterior is only as strong as its weakest point. Insects, water and even small rodents can find their way in through missing window caulking. The best thing homeowners can do is monitor window caulk and replace it when it becomes ineffective.

Here’s a guide to spotting and removing old window caulking.

How to Know When It’s Time for New Caulking

Knowing when to replace caulk is fairly straightforward. Homeowners should look for obvious signs of decay around windowpanes. Anytime there are visible gaps in caulk lines, it’s a good indication that it’s deteriorated enough to warrant removal and putting in new caulk.

Likewise, it can probably be switched out if there’s a lot of cracking along caulk seams. If it looks like it’s going to fall out, or if there’s a chance water can leak inside, it’s time for some new caulk. Additionally, some people decide to replace caulking just because they don’t like the dried-out look of older caulk.

An Easy Guide to Caulk Removal

Getting rid of caulk from windows isn’t complicated. Ultimately, it takes time and some elbow grease. Caulk removal requires a few basic tools to help get the job done faster.

  1. Strong Putty Knife – First, you need something to remove the large chunks of dried caulk. This can be done with a hefty putty knife or a flathead screwdriver. You need to be able to scrape through the caulk line with something that has a little leverage you can use to force the caulking out of the seam. Putty knives are great on windows as well because they can be used to scrape caulking that’s stuck on glass panes. Gently scrape the caulking at an angle so it comes off without scratching the glass.
  2. Wire Brush – A wire brush is the prefect too for getting out all the loose crumbs left behind after the putty knife is used. Simply scrub the area with the wire brush. It’s important to get all the small crumbs out so new caulking can go into clean seams.
  3. Heat Gun – A heat gun is a great way to loosen up stuck or stubborn caulk. Sometimes, no matter how much strength you use with the putty knife, some caulk just won’t budge. The heat gun softens caulk so it’s easier to pull out. Be careful, though, not to overheat caulking. It can melt and gets really sticky on brick, siding or windows.

All of these tools are very common and can be purchased at a local hardware store or big box home improvement chain. When the entire area is clear, use a wet rag or sponge to wash the area. You want to make sure that no residue or crumbs are left around that could contaminate new caulk.
