Many many problem of house

Recent surveys by U.S. and Canadian home inspectors resulted in this list of the ten problems most frequently found in the homes they have inspected:

1. Improper Surface Grading/Drainage

This was by far the most frequently found problem, reported by 35.8% of the survey respondents. It is responsible for the most common of household maladies, including water penetration of the basement and crawlspace.

2. Improper Electrical Wiring

A significant number (19.9%) chose this item as the most common home defect, which includes such situations as insufficient electrical service to the house, inadequate overload protection, and amateur and often dangerous wiring connections.

3. Roof Damage

Although reported by only 8.5% of the respondents as the most common problem, roof leakage caused by old or damaged shingles or improper flashing was considered by inspectors to be a frequent problem.

4. Heating Systems

Problems in this category include broken or malfunctioning operation controls, blocked chimneys, and unsafe exhaust disposal.

5. Poor Overall Maintenance

Even the novice home buyer is usually aware of this situation, demonstrated by such signs as cracked, peeling and dirty, painted surfaces, crumbling masonry, makeshift wiring and plumbing, and broken fixtures and appliances.

6. Structurally Related Problems

Many houses, as a result of problems in one or more of the other categories, sustain damage to such structural components as foundation walls, floor joists, rafters, and window and door headers.

7. Plumbing

Though not ranked by the respondents as a Number One problem, plumbing defects still rank high among the house problems encountered, and include the existence of old and incompatible piping materials, as well as faulty fixtures and waste lines.

8. Exteriors

Flaws in a home's exterior, including windows, doors, and wall surfaces, are responsible for water and air penetration, but rarely have structural significance. Inadequate caulking and/or weatherstripping are the most common culprits.

9. Poor Ventilation

Perhaps due to overly ambitious efforts to save energy, many home owners have over-sealed their homes, resulting in excessive interior moisture. This can cause rotting and premature failure of both structural and non-structural elements.

10. Miscellaneous

This category includes primarily interior components, often cosmetic in nature, which were not found frequently enough to rank individually in our survey.
