9 Most Costly Home Repairs and Maintenance

Before we begin, if you are concerned about any of these issues, please contact a repair professional immediately. Some of the issues below are dangerous to your health – other issues are just expensive fixes. If you believe you are in any danger, please contact a specialist.

Using our experience of past remodels, we created a list of the most expensive home repairs we’ve seen. If you’re buying one of our turn-key homes, these sort of repairs won’t be an issue. If you are selling your home, however, you may need to make some of these repairs before listing. Luckily companies like ours can step in and offer cash for your home when repair costs are too high or a home owner simply wants to move on without spending the time to make these repairs.

These are the 9 most expensive repairs we’ve seen ranked by cost from lowest to highest:

Heating / AC / HVAC

Cost: $300 - $1,200; Up to $12,000 if you need a full replacement

If you are sweating a bit more than expected in the summer or not able to properly heat your home in the winter, that might be a sign that something is going awry. You may also notice that your unit is leaking or making strange noises. Some repairs are a quick fix, but if you’ve put it off for too long, you may need a full replacement.

Water Heater

Cost: $500 - $1,500

Just like your cooling or heating system going out, you’ll notice leaks and noises coming from your water heater if it is starting to go out. The worst sign – rusty water leaking from your water heater. Fortunately this is all around one of the most affordable home repairs.


Cost: $300 - $3,000; Up to $25,000 if you have to completely rewire your home

Sometimes circuit breakers trip and that’s ok, but if this is a usual occurrence, it could signal a larger electrical issue in your home. You may also notice shocks from outlets or appliances, flickering lights, and visible damage to wires. This is all much more likely in an older home. Get this checked immediately because electrical damage can cause a fire.


Cost: $1,000 - $4,000

Mold is usually harmless if discovered early, but it quickly becomes a difficult issue to resolve. Some mold is even hazardous for you and your family. If you notice a musty odor, discoloration of your walls, black spots near areas of water (like your water heater or windows), and especially any unexplained or unusual allergic reactions – seek help right away. Your situation might be harmless, but it isn’t worth the risk.

Water Damage

Cost: $1,000 - $5,000

If not resolved quickly, water damage could create other various expensive issues in your home. Some signs of water damage are easy to spot like leaks, a musty smell, and visual changes in your walls or ceilings. Others are less noticeable like an unusually high increase in your water bill or lower water pressure.

Roof Repair

Cost: $3,000 - $6,000; Full replacement up to $25,000

A leak is the most obvious sign that your roof needs to be repaired, but even curling and missing shingles signals that you’ll need to have some work on your roof done. While repairing your roof adds value to your home, it could be quite costly and ultimately you won’t recoup that entire investment in the value of your home. Most estimates are around 90% of the cost can be recouped in the updated value of the home.


Cost:$500 - $7,000

While small cracks and more significant issues with your foundation will skew from the range, expect around $2,000 - $7,000 if issues with your foundation are found during your inspection. You may notice warping floors, fractures in your walls, and doors and windows that are difficult to open or close. The earlier you catch it, the better.

Termite Damage

Cost – $2,000 - $8,000

Termite damage is often noticed once it’s too late and the damage has already been done. Keep wooden parts of your home away from the ground if possible and keep an eye out for small flying bugs, bug wings laying around, crumbling wood, and mud tubes on the side of your home. If you are concerned about termites, you may notice a hollow sound when knocking on wood. Don’t wait to resolve this issue.

Plumbing / Septic / Sewer

Cost – $500 – $10,000

Plumbing and sewer issues are the most expensive and disgusting repairs a home owner will have to deal with. You may notice discoloration of exposed pipes, various leaks, rusty water, toilets that won’t flush, slow drains, and smelly water in your yard. Luckily these issues rarely skyrocket into a much higher dollar amount like roof repair or electrical work.

If you are having any issues with your home and can’t afford to repair it yourself, there are plenty of options. One viable option is selling your home and moving on. While it is difficult to say goodbye to you family home, it could get you and your family out of potentially dangerous environments.
