How to Repair a Metal Window Awning

What You'll Need
Lemon juice or vinegar
Nylon scrubber
Mounting hardware
Screwdriver and wrench (to repair damaged hardware)
Weatherstripping or caulk

A metal window awning can add beauty and value to your home. They help keep your home cooler by reflecting sunlight that would ordinarily hit the window. They also help protect the window and frame from the elements. However, when a metal window awning falls into disrepair it can look ugly and be a nightmare to deal with. Here are some simple ways to repair some of the most common problems.

Step 1: Visible Signs of Damage

Since a metal awning is exposed to weather constantly, it's not uncommon to find bends or dents in the metal. Not only does this look unattractive, it can lead to rust. Depending on the size of the dent, and the placement, repairing this can be simple. If the dent is on the awning itself, you can try to pull the dent out using a plunger. You will want to be able to access the dent safely, and this means you may need to either crawl onto your roof with a friend standing by, or remove the awning altogether. Use a small plunger and wet the edges slightly. This will help the plunger maintain a solid hold. Try to plunge the dent out.

Step 2: Dealing with Rust

Rust will eat at metal relatively quickly. It also looks terrible. You can generally clean away rust with a little lemon juice or vinegar. Taking care of rust before it gets out of hand is the best approach to take. Simply use a nylon scrubber and rub the rust away. There are products available that can be painted or sprayed on the awning to prevent future rust. You can find these products at any home improvement store. Keeping your awning clean by getting it pressure washed once a year will help prevent future damage from rust as well.

Step 3: Security

Hinges, bolts and other mounting hardware won't outlast the life of the awning itself. Damaged hardware can cause the awning to buckle or fall under pressure. Sometimes it just takes a good rain storm to alert you to a problem. Check the hardware that's used on the awning every so often to avoid major headaches. Replace hinges or bolts that look loose or damaged. You also want to check where the awning is attached to the home. Siding that is falling or loose mortar can create a dangerous situation as well. Secure any siding that has come loose, and repair anything that looks compromised.

Step 4: Seals

Depending on how your awning was installed, you may have weatherproofing strips attached between the awning and the wall. This protects the exterior finish of your home by not allowing water to accumulate under the awning. Without this, ugly stains and damage to siding can start to happen. If the seals are worn, they are simple to replace. Simply find the weatherstripping material that is best for your area. Remove the old stripping, and replace it. Some awnings simply use a weatherproof caulk, and this is the easiest way to create a weather proof seal.
