Home improvement is the process of renovating, making additions, or performing improvements to a residence. This practice involves changing the interior, exterior, or the surrounding property of a home.

Interior improvements often focus on upgrading electrical or plumbing systems. Exterior projects might include masonry, concrete, siding, or roofing work. Beyond the house itself, improvements can extend to the garden or garage. People engage in these projects for many reasons, such as personal comfort, maintenance, or safety.

One primary goal of home improvement is increasing personal comfort. Homeowners may upgrade their HVAC systems, which stands for heating, ventilation, and air conditioning. Some people add luxury features, such as gourmet kitchen elements or hot tub spas in bathrooms. Other comfort-based projects involve increasing the capacity of plumbing and electrical systems. Homeowners might also choose to waterproof basements or soundproof rooms like bedrooms and baths. These changes aim to make the living environment more pleasant and functional.

Maintenance and repair are also essential parts of the process. These tasks keep a home in good condition and prevent decay. Common maintenance projects include roof tear-off and replacement or installing new windows. People may perform concrete and masonry repairs on foundations and chimneys. Smaller tasks involve repainting walls or fences, repairing plumbing, or even polishing furniture.

Such work ensures the structure remains stable and visually appealing over time.

Some homeowners seek to add more living space through structural changes. One method is turning marginal areas into usable rooms. For example, an attic might become a spare bedroom, or a basement might become a home theater. Another method is extending the house by adding rooms to the side. Sometimes, people add extra levels to the original roof. These new units of construction are known as add-ons.

These additions allow a home to grow with its inhabitants.

Energy efficiency and safety are two other major drivers for improvement. To save energy, people install thermal insulation, replacement windows, or efficient lighting. They may also use renewable energy like solar panels, wind turbines, or geothermal exchange heat pumps. Safety improvements can protect a home from many different hazards. Fire protection includes installing smoke detectors, fire alarms, or automatic fire sprinkler systems. Physical security can involve adding locks, security lighting, or video surveillance.

Some even build storm cellars for protection during severe weather.

Professional home improvement is an ancient practice with deep historical roots. In the 1st century B.C., a man named Sergius Orata is said to have invented the hypocaust. According to the writer Vitruvius, the hypocaust was an underfloor heating system. It was used throughout the Roman Empire in the villas of wealthy citizens. Orata reportedly became wealthy by buying villas, adding spas and hypocausts, and reselling them. This shows that improving property value is a very old concept.

Today, home improvement is a massive global industry. In the United States, residential renovation is an almost $300 billion industry. In Canada, the industry is valued at $48 billion. The average cost per project is $3,000 in the U.S., while in Canada, projects average between $11,000 and $15,000. Many people hire renovation contractors, who are skilled tradespeople with specialized credentials.

Others use aggregators, which are companies that act as intermediaries between customers and service providers.

Home improvement has also become a significant part of popular culture. The television show *This Old House* premiered on PBS in 1979 and helped popularize the topic. Channels like HGTV and DIY Network feature many shows about do-it-yourself projects. Even movies have explored the subject, sometimes for humor. Films like *The Money Pit* or the sitcom *Home Improvement* use the challenges of renovation as comedic themes. Whether for necessity or hobby, home improvement remains a central part of modern life.
