Aluminum siding is one of the most popular types of siding which is in common use today. There are many advantages for anyone using aluminum siding. Aluminum is rust resistant and also resistant to fire and many other problems. The only real problems which can affect aluminum siding is loose siding.

Over time, aluminum siding can become battered and damaged by storms and bad weather conditions. This will loosen and cause damage to the aluminum siding panels which could potentially cause them to come away from the wall. Learning how to re-attach aluminum siding corner joints will make it possible to make your siding last much longer with minimal repairs.

Aluminum siding is fixed to the exterior of your wall using nails. It's important that only aluminum nails are used to prevent any problems with potential corrosion issues. The aluminum siding corner joints are fitted in the same way.

Step 1 - Assessing the Condition

The very first thing that you will need to do is take a look at the condition of the aluminum and decide what you need to do with it. If it's just minor damage then it might be possible to repair rather than replace. However if it's a more serious problem then you will need to consider replacing the entire sections of aluminum siding with new pieces which are much stronger and in better condition.

Almost all aluminum siding panels are nailed into position but they are also interlocking panels. This means that they will need to be carefully clipped into place before they can be nailed into position.

Although this guide is interested in repairing the loose corner panels of siding that's not the only thing that you're interested in. Take a look at the straight panels too as it would be easier to replace everything at the same time.

Step 2 - Locating the Loose Panels

Once you've spent some time looking at the problem you should be able to identify the loose panels. It's worth locating all of these loose panels so that you can decide how to replace them.

Step 3 - Unclipping the Corner Panels

Now you need to unclip the corner panels by sliding the siding unlock tool under the siding corner sections and slowly lifting up. This should help to remove the nails and unclip the section in question. Once you have removed the corners you can then use the same technique to remove any damaged or broken siding panels which can then be replaced at the same time.

Step 4 - Replacing the Panel

You will now need to tuck a replacement corner panel up into the void behind the panel above it, this might be tricky and may be easier if you slightly loosen the panel above. Then fix new nails into the pre-drilled holes and hammer it home securely. Don't fix the panels together too tightly though because this can actually cause more harm than good should the panels ever expand due to changing weather conditions. Then clip the two sections together and the siding is secure.
