How to Fix Leaks in a Deck Awning

You may not feel like it is your lucky day when you discover a leak in your deck — but you will be delighted to know that it is a simple repair job. If you have ever used glue to fix a broken plate or utilized tape to wrap a gift, then you can fix a leak on your deck. Whether your awning is made from aluminum or fabric, be certain to start this fix job using a clean surface.

Fix an Aluminum Awning

Clean out the area surrounding the leak. The surface must be free of dirt, grease, oil, rust, tar and some other contaminant that will inhibit a proper seal. Wash the awning using a combination of warm water and mild dish soap, using a wire brush. Dry the area thoroughly using a rag or towel.

Make sure that it’s at least 30 degrees Fahrenheit outdoors or at your work area before proceeding. Squeeze the sealant onto the awning to fill the gap or hole. If the gap or hole is long and narrow, apply the sealant in one long stroke, avoiding stops and starts that could dry into miniature mounds. Gently press on the sealant into place using the tip of the nozzle.

Survey your work and then wipe away any excess sealant with a rag. Many polyether sealants dry quickly. Check the instructions on the package before exposing your awning into the elements.

Fix a Fabric or Vinyl Awning

Clean out the awning so dirt does not interfere with a proper seal. Wash the awning using a combination of warm water and mild dish soap, using a soft sponge. Dry the area thoroughly using a rag or towel.

Assess the size of the hole at the awning. Cut a slice of repair tape that is slightly larger than the hole. If your repair tape is narrow and the hole is circular, cut a few pieces of tape to ensure appropriate coverage. Multiply the amount of bits you need times 2, and then cut the tape. You’ll use the next pair of tape pieces to reinforce the back of the awning.

Put the awning on a flat surface. Smooth out any wrinkles. Place the repair tape snugly over the hole. If you’re using multiple pieces of tape, then slightly overlap one piece over the other. Flip the awning over and repeat the procedure on the opposite side.
