6. Driveway problems

Average cost to repair: $5,000

Asphalt drivewaystake a beating. Not only must they withstand the weight of large vehicles, but they must suffer through the seasons: cold and ice in the winter and extreme heat and rain in the summer and spring. It's no surprise that asphalt driveways are prone to cracking and crumbling if left unprotected. The average cost of installing a brand-new drivewayis around $5,000, but don't forget the added expense of digging up and hauling away the old one [source: HomeAdvisor].

7. Termite infestations

Average cost to repair: $3,000

8. Water line breaks

Average cost to repair: $2,000

Your water and sewerlines connect your home to the public water and sewage systems (assuming you don't have your own septic tank). Your city or town's liability for the system ends at the street; homeowners are responsible for the length of pipe underneath their property. The cost of physically repairing or replacing a broken water or sewage line isn't going to break the bank — somewhere between $1,000 and $2,000. What's really going to cost you is cleaning up the mess [source:HomeAdvisor ].

When a mainwater line breaks, it creates an underground flood that seeps up to your lawn, creating huge marsh-like puddles. To get to the source of the leak, crews will have to excavate into your lawn and possibly under trees and driveways. After you pay for repairing the water line, you'll pay to replace the section of driveway and re-landscape the lawn, another several thousand dollars literally down the drain.

9. Leaks and water damage

Average cost to repair: about $12 per square foot

When places that are supposed to remain dry get wet for long periods of time, big problems result. Water is a killer. It seeps through concrete, sprouts mold and empties wallets. With a cost of nearly $12 per square foot in some areas (according toHomewyse), water damage in a large, 500-square-foot area can cost you $6,000, Not to mention any potential added costs for plumbing repairs and mold remediation services.
