Doing your own home repairs can be a great way to save money and put a personal stamp on your space. There’s also a pretty good feeling that comes with looking at a finished project and knowing you did the work yourself.
Still, DIY projects can go wrong in ways that cost much more than hiring a professional in the first place. Some mistakes can even create problems with your home insurance, especially if the work causes damage or doesn’t meet local building or safety requirements.
Here are some common homeowner mistakes that could lead to an insurance headache, plus a few ways to avoid them.
Using Cheap or Incorrect Materials
Saving a little money on materials can seem like a smart move, but the wrong supplies can create problems later. Using wiring that isn’t rated for the job, roofing materials that aren’t appropriate for your climate, or other substandard products can leave your home vulnerable to damage.
If an insurance claim comes up, the insurer may look at whether the work was done correctly and whether suitable materials were used. Spending a little more on the right supplies can save you from having to redo the project later.
Doing Electrical Work Without the Right Knowledge
Electrical projects aren’t a good place to learn through trial and error. A loose connection, overloaded circuit, or incorrectly installed wire can lead to a fire, electrical shock, or serious damage to your home.
If you aren’t familiar with electrical work, hiring a licensed electrician is usually the safer choice. A small mistake behind a wall can turn into a very expensive problem.
Failing to Tell Your Insurance Company About Major Changes
A major renovation can change both the value and the risks associated with your home. Adding a room, finishing a basement, replacing a roof, or doing a major kitchen remodel may be worth mentioning to your insurer before or during the project.
Leaving major changes off your policy could leave you with less coverage than you expected. Your insurer can also have specific requirements for certain renovations, so checking before work begins can prevent unpleasant surprises later.
Overlooking Water Damage Risks
DIY plumbing can be tempting, especially when a repair looks like something that should take only an hour. The trouble is that a small mistake can send water behind a wall, under flooring, or into cabinets where you may not notice it right away.
A slow leak can cause mold, damaged wood, ruined flooring, and other costly repairs. If you’re unsure about a plumbing project, getting help before the work begins can be much cheaper than dealing with water damage afterward.
Damaging Old Plumbing During a Renovation
A renovation often involves opening walls, removing cabinets, or moving fixtures, which can put old pipes at risk. Plumbing that has already weakened with age can crack or start leaking after being disturbed.
Before starting a major DIY renovation, check what is behind the walls and under the floors. Older plumbing may need attention before you continue with the rest of the project.
Removing a Load-Bearing Wall
An open floor plan can make a home feel larger, but knocking down a wall isn’t as simple as grabbing a sledgehammer. Some walls support the structure above them, and removing one without the proper support can cause serious structural problems.
Before removing any wall, find out whether it is load-bearing. A structural engineer or qualified contractor can determine what needs to be supported before any demolition starts. Structural damage caused by unauthorized or improper work can also create insurance complications.
Ignoring Fire Safety During a Renovation
Renovations can introduce new fire risks, especially in kitchens, around fireplaces, or near heating equipment. Installing the wrong materials or placing combustible materials too close to a heat source can create a dangerous situation.
Pay attention to fire-rated materials, smoke detectors, electrical requirements, and proper spacing around appliances. A few extra safety checks can make a big difference once the renovation is finished.
Installing or Repairing a Roof Incorrectly
Roof work may look straightforward from the ground, but there’s a lot that can go wrong once you’re up there. According to Dakota Roofing, roofing jobs can be much harder than they appear.
Missing flashing, loose shingles, poor sealing, or improper installation can allow water into the home. If a storm later causes damage to a roof that was poorly installed, the insurer may examine whether the earlier work contributed to the problem.
Roof repairs also come with fall risks, so this is one DIY project where calling a professional can be worth the expense.
Skipping Required Safety Features
Some home projects come with safety requirements that are easy to overlook. Installing a swimming pool, wood-burning stove, fireplace, or other major feature may require items such as fencing, barriers, ventilation, or smoke and carbon monoxide detectors.
Leaving out those features could create safety risks and may cause problems with an insurance claim if an accident occurs. Check your local requirements and your insurance policy before finishing the project.
Skipping Permits
A permit may feel like an annoying extra step, but certain renovations require one before work can begin. Electrical, plumbing, structural, and major remodeling projects are common examples.
Investopedia notes that many home improvements require permits, depending on the type of work and local rules.
Skipping the permit can lead to fines or an order to correct the work. It can also create questions about the project if you later need to file an insurance claim. Check with your local building department before starting a project that could require approval.
Skipping a Professional Inspection
Finishing a DIY project can feel like the hard part is over, but having the work checked afterward can catch problems you may have missed.
This is especially useful for electrical, plumbing, structural, roofing, and gas-related projects. A licensed professional may spot an issue that isn’t obvious to someone without the same training.
Spending money on an inspection may feel unnecessary after you’ve already completed the work, but finding a problem early is usually easier than fixing it after it causes damage.
Forgetting to Update Your Coverage After a Major Project
A major renovation can change how much your home is worth and how much it would cost to rebuild. A new kitchen, finished basement, bathroom addition, or extra living space may mean your existing coverage no longer reflects the home accurately.
After completing a major project, review your home insurance policy and ask your insurer whether your coverage needs to be adjusted.
Keeping your insurer informed also gives you a chance to ask about any new requirements that apply to the improvements you’ve made.
Making Landscaping Mistakes Near Your Home
Landscaping may seem far removed from home insurance, but where you place plants, trees, and drainage features can affect your house.
Trees planted too close to the foundation can send roots toward underground pipes or foundations. Poor drainage can send water toward the house and contribute to moisture problems or foundation damage.
Before planting large trees or changing the slope of your yard, think about where rainwater will go and how mature plants will affect the property years from now.
Installing Your Own Security System Incorrectly
Installing a security system yourself can save money, but a poorly placed camera, sensor, alarm, or door contact can leave gaps in your home’s protection.
Some insurance companies also offer discounts for certain security systems, but the requirements can vary. A system that qualifies for a discount may need to meet particular standards or be professionally monitored or installed.
Before buying equipment, check with your insurer to find out what qualifies for a discount and whether there are installation requirements. A little research can help you avoid paying for a system that doesn’t provide the coverage benefit you expected.
