Ever start a “simple” project… and it turns into drywall work, shim trimming, and figuring it out as you go? Same. In this episode of The Fix, Tucker and Travis head to Travis’s house to install matching 2.25" clamshell door trim - but there’s a gap big enough to derail the whole plan. So we show you how to patch the gap with drywall & joint compound, then install door trim the right way with a clean 1/8" reveal, tight miters, and a pro-looking finish. What you’ll learn in this video:• How to prep a door opening when the drywall doesn’t meet the jamb • Trimming shims flush using an oscillating tool • Adding backing blocks so your drywall patch has something solid to grab • Cutting a drywall strip (score & snap) and rasping for a perfect fit • Mud & tape basics to help prevent cracking • Setting your reveal and cutting trim miters without overcomplicating measurements • Using 18ga brad nails (short for the jamb, long to catch studs) • Final steps: fill nail holes, caulk gaps, touch up paint
