DIY Repair Wood Rot & Termite Damage on Door Frame - a DIY 1st Timer Attempt

Termites were damaging my door frame. There was wood rot where the sprinkler was damaging the wood. This is my attempt to repair it. Not too shabby for no prior experience. If I can do it… (you know the rest). Of course, this is not professional advice and there are no guarantees to effectiveness, process, etc. Use PPE and do any work at your own risk. I’m sharing my first-time experience and do not claim to be deeply knowledgeable about construction. Just trying to save a dime, make small improvements and prevent further damage. Have a blessed day!
