Who doesn’t love a good DIY project? However, there are some things you can do around your house that will make it less valuable. If you ever want to sell your home, these seven handyman “tricks” could actually tank your resale value.
1. Covering Hardwood Floors with Laminate or Carpet
Hardwood floors are one of the top features buyers look for in a home. But many DIYers mistakenly cover them up with cheap laminate or wall-to-wall carpet, thinking they’re upgrading. While it might seem cozier or more modern, you’re actually hiding one of your home’s most valuable assets. Buyers may wonder what you’re concealing—or worse, never know there’s hardwood underneath at all. If you must add something, use area rugs that can be removed easily.
2. Creating an “Open Concept” Without a Plan
Tearing down walls might sound like a fast way to modernize your space. But knocking down a wall without understanding the structure can be a major risk. Load-bearing walls, electrical lines, and plumbing are all hiding behind that drywall. Plus, some buyers now prefer defined spaces like offices or dining rooms, especially post-pandemic. That open floor plan you created might actually make your home feel incomplete or poorly planned.
3. DIY Plumbing Projects with No Permit
Replacing a faucet is one thing, but installing new pipes or moving a bathroom? That’s where unlicensed work becomes a serious problem. DIY plumbing without the proper permits can cause code violations and major water damage. Worse, it may make your home harder to sell, as buyers may request licensed inspections or demand repairs before closing. Always pull permits and, when in doubt, hire a pro for big plumbing tasks.
4. Overbuilt Additions That Don’t Match
Adding a room or deck might seem like a value booster, but it can backfire if it clashes with the rest of the home. A too-large sunroom on a small ranch-style house, for example, looks awkward and throws off the home’s proportions. Buyers want functional space that flows with the existing structure, not something that looks tacked on. If your addition feels more like a patch job than an upgrade, it may hurt curb appeal and appraisals. Always design with balance and scale in mind.
5. Painting Everything a Wild Color
A fresh coat of paint is one of the easiest and cheapest DIY upgrades, but color matters more than people realize. Bright reds, purples, or trendy pastels might reflect your personal style, but they often turn off buyers. The cost of repainting, especially in high-traffic rooms, becomes a mental deduction from your home’s value. Stick to neutral colors if resale is anywhere in your future. You can always add color with art and furniture instead.
6. Removing Closets to Make Rooms Bigger
Trying to create the illusion of more space by removing closets might seem like a smart idea. But storage is a major selling point for modern buyers. Taking out a closet—even in a guest room or hallway—can turn a functional bedroom into a glorified bonus space. Fewer closets often lead buyers to assume they’ll need to invest in costly storage solutions. Instead of removing them, consider reconfiguring closet interiors to improve functionality.
7. Poorly Installed Tile or Flooring
Installing tile, vinyl planks, or hardwood sounds simple enough—until you do it wrong. Uneven floors, misaligned tiles, or visible seams scream “amateur work.” Not only is it unsightly, but it can raise concerns about what’s underneath, such as water damage or structural issues. These flaws will definitely get flagged in a home inspection and could reduce your sale price. If you’re not confident, bring in a contractor to ensure the work meets market standards.
Sometimes the Smartest DIY Move Is Not to DIY at All
Most people think that when they make changes to their home that they are improving the value of their home. Some projects can actually hurt you more than help when it comes time to sell (or even refinance). So, before you pick up a hammer and start your next renovation, ask yourself if it matches something that buyers are actually looking for. When in doubt, contact a professional and get a second opinion. It could save you a lot of heartache in the long run.
