Homeowners insurance is supposed to be your safety net. You pay your premiums, you expect protection. But what if a simple mistake could leave you with nothing? Many people love a good DIY project. It saves money, feels rewarding, and sometimes even looks great. But there’s a hidden risk: one wrong move can void your entire homeowners insurance policy. That means if something goes wrong, you’re on your own. Understanding what can trigger this is key to protecting your home and your wallet.
1. Unpermitted Renovations
Doing home improvements without the right permits is a common DIY mistake. It’s tempting to skip the paperwork. Permits cost money and take time. But if you remodel your kitchen, add a bathroom, or finish your basement without a permit, you’re taking a big risk with your homeowners insurance. If a fire starts in your new, unpermitted addition, your insurer can deny your claim. They may even cancel your policy. Insurers want to know that all work meets local building codes. Permits are proof. Without them, you can’t show that the work was done safely or legally. Always check with your city or county before starting any major project. It’s not just about following the rules—it’s about keeping your coverage.
2. Faulty Electrical Work
Electrical projects are popular with DIYers. Swapping out a light fixture or adding an outlet seems simple. But electrical mistakes are a leading cause of house fires. If you do your own wiring and something goes wrong, your homeowners insurance may not cover the damage. Insurers expect licensed professionals to handle electrical work. If you can’t show that a qualified electrician did the job, your claim could be denied. Even if you think you know what you’re doing, the risk isn’t worth it. Electrical codes exist for a reason. Faulty wiring can smolder for months before causing a fire. To keep your homeowners insurance valid, consider hiring a professional for any tasks beyond the basics.
3. Plumbing Projects Gone Wrong
Leaky pipes and clogged drains are annoying. Many people try to fix them on their own. But plumbing mistakes can cause major water damage. If you install a new water heater or reroute pipes without the right skills, you could flood your home. Insurance companies may refuse to pay for water damage if a licensed plumber didn’t do the work. They might also deny claims if you used the wrong materials or ignored local codes. Water damage is expensive and can lead to mold, which is even harder to fix. Before you tackle a plumbing project, ask yourself if you’re really qualified. If not, call a professional. It’s the best way to protect your homeowners insurance.
4. Roof Repairs Without a Professional
Your roof is your home’s first line of defense. It keeps out rain, snow, and wind. Some homeowners try to save money by fixing their own roofs. But improper repairs can lead to leaks, structural damage, and even collapse. If your insurer finds out you did your own roof work and it failed, they can deny your claim. Some policies even require proof that a licensed roofer did the job. Roof repairs are dangerous, too. Falls from roofs are a leading cause of injury. If you get hurt, your medical bills might not be covered. And if your repair causes damage to a neighbor’s property, you could be liable. When it comes to your roof, don’t risk your homeowners insurance. Hire a professional.
5. Installing Pools or Trampolines
Adding a pool or trampoline seems like a fun upgrade. But these features come with big risks. Many insurance companies have strict rules about pools and trampolines. If you install one without telling your insurer, you could void your policy. Pools and trampolines increase the chance of injury. If someone gets hurt and you didn’t disclose the new feature, your insurance may not cover the claim. Some insurers won’t cover homes with trampolines at all. Always check your policy before adding anything that could be considered a liability risk. And make sure you follow all safety requirements, like fences and covers for pools. Protect your homeowners insurance by being upfront about changes.
6. Ignoring Regular Maintenance
Homeowners insurance is not a maintenance plan. If you ignore basic upkeep, your insurer can deny claims for resulting damage. For example, if you never clean your gutters and water backs up into your home, that’s on you. The same goes for failing to fix a leaky roof or ignoring signs of termites. Insurance covers sudden, accidental damage—not problems caused by neglect. Keep records of your maintenance. Take photos, save receipts, and document repairs. This helps prove you did your part if you ever need to file a claim. Regular maintenance keeps your home safe and your homeowners insurance valid.
7. Using the Wrong Materials
Cutting corners with cheap or improper materials can backfire. If you use the wrong type of wiring, pipes, or roofing, you may violate building codes. Insurers can deny claims if they find out you used materials that don’t meet standards. For example, using indoor wiring outside or plastic pipes where metal is required can lead to big problems. Always use materials approved for your project. If you’re not sure, ask a professional or check your local building codes. Using the right materials protects your home and your homeowners insurance.
8. Failing to Disclose Major Changes
Any major change to your home should be reported to your insurance company. This includes renovations, additions, or new features like a wood stove. If you don’t update your policy, you could be underinsured or not covered at all. Insurers need accurate information to assess risk. If you fail to disclose changes, your homeowners insurance could be voided. Always call your agent before starting a big project. It’s better to pay a little more for coverage than to lose it entirely.
Protect Your Homeowners Insurance with Smart DIY Choices
DIY projects can be rewarding, but they come with risks. The biggest mistake is thinking you can do it all without help. Unpermitted renovations, faulty electrical or plumbing work, and failing to disclose changes can all void your homeowners insurance. Always check your policy, get the right permits, and hire professionals when needed. Your home is your biggest investment. Protect it by making smart choices and keeping your homeowners insurance valid. And if you want to know more about building codes and permits, visit your local government’s website.
