There\u2019s no denying the charm of wood trim. Crown molding<\/a>, baseboards, window and door frames, mantels, and other millwork can add warmth, character, and definition to any space.<\/p>\n

But like any home improvement<\/a>, precision is key.<\/p>\n

If there are gaps between where the connecting pieces of wood trim come together \u2014 such as between the baseboards and the floor, where the wood trim<\/a> meets the walls, or the inside corners of window frames or baseboards \u2014 it can result in a sloppy, unfinished look.<\/p>\n\n\n\n\n\n

Why fill in the gaps?<\/h2>\n

The main purpose of wood trim is to add a polished, finished look to the room, and a large gap will detract from that goal by drawing the eye to that glaring imperfection. \u201cWhy put in all of that hard work and not take care of this final small detail?\u201d posits Craig Russell<\/a>, founder and CEO of an award-winning building company in Cincinnati, Ohio.<\/p>\n

If you plan to put your home on the market soon<\/a>, filling trim gaps should definitely have a spot on your pre-listing checklist<\/a>. It may seem like a small detail, but discerning buyers will notice the issue during showings<\/a> and inspections<\/a>. And if you\u2019ll be painting your wood trim, you\u2019ll need to fill the gaps beforehand to ensure a smooth, even finish.<\/p>\n

Beyond looking sloppy, large gaps in wood trim can cause more serious issues. Eric Regan<\/a>, owner of Mission Painting & Home Improvements, warns that if the problem isn\u2019t corrected, water can seep through and penetrate the wood behind the gaps, which will eventually cause it to rot. It can also provide an entry point for bugs and can allow hot or cold air to escape, forcing your HVAC system<\/a> to have to work harder to regulate the indoor temperature.<\/p>\n

Now that you know why it\u2019s so important to fix large gaps in wood trim, what\u2019s the best way to tackle it? If you\u2019re short on time and have the budget for outsourcing the job, you can always hire a company or a handyman<\/a>. But if you enjoy dabbling in DIY projects and have a good amount of time and patience, you can get rid of those gaps yourself in seven relatively simple steps.<\/p>\n
