Home Improvement

Vertical Available – Demo Only

The concept of home improvement, home renovation, or remodelling is the process of renovating or making additions to one’s home. Home improvement can be projects that upgrade an existing home interior (such as electrical and plumbing), exterior (masonry, concrete, siding, roofing), or other improvements to the property (i.e. garden work or garage maintenance/additions).

Types of home improvement

While “home improvement” often refers to building projects that alter the structure of an existing home, it can also include improvements to lawns, gardens, and outdoor structures, such as gazebos and garages. It also encompasses maintenance, repair, and general servicing tasks. Home improvement projects generally have one or more of the following goals:^[1]

Comfort

Upgrading heating, ventilation and air conditioning systems (HVAC).
Upgrading rooms with luxuries, such as adding gourmet features to a kitchen or a hot tub spa to a bathroom.
Increasing the capacity of plumbing and electrical systems.
Waterproofing basements.
Soundproofing rooms, especially bedrooms and baths.

Maintenance and repair

Maintenance projects can include:

Roof tear-off and replacement.
Replacement or new construction windows.
Concrete and masonry repairs to the foundation and chimney.
Repainting rooms, walls or fences
Repairing plumbing and electrical systems
Wall papers
Furniture polish

Additional space

Additional living space may be added by:

Turning marginal areas into livable spaces such as turning basements into recrooms, home theaters, or home offices – or attics into spare bedrooms.
Extending one’s house with rooms added to the side of one’s home or, sometimes, extra levels to the original roof. Such a new unit of construction is called an “add-on”.^[2]

Saving energy

Homeowners may reduce utility costs with:

Energy-efficient thermal insulation, replacement windows, and lighting.
Renewable energy with biomass pellet stoves, wood-burning stoves, solar panels, wind turbines, programmable thermostats,^[3] and geothermal exchange heat pumps (see autonomous building).

Safety and preparedness

Emergency preparedness safety measures such as:

Home fire and burglar alarm systems.
Fire sprinkler systems to protect homes from fires.
Security doors, windows, and shutters.
Storm cellars as protection from tornadoes and hurricanes.
Bomb shelters especially during the 1950s as protection from nuclear war.
Backup generators for providing power during power outages.

Home improvement industry

Home or residential renovation is an almost $300 billion industry in the United States,^[4] and a $48 billion industry in Canada.^[5]^{[full citation needed]} The average cost per project is $3,000 in the United States and $11,000–15,000 in Canada.

Professional home improvement is ancient and goes back to the beginning of recorded civilization. One example is Sergius Orata, who in the 1st century B.C. is said by the writer Vitruvius (in his famous book De architectura) to have invented the hypocaust. The hypocaust is an underfloor heating system that was used throughout the Roman empire in villas of the wealthy. He is said to have become wealthy himself by buying villas at a low price, adding spas and his newly invented hypocaust, and reselling them at higher prices.

Renovation contractors

Perhaps the most important or visible professionals in the renovation industry are renovation contractors or skilled trades. These are the builders that have specialized credentials, licensing and experience to perform renovation services in specific municipalities.

While there is a fairly large ‘grey market’ of unlicensed companies, there are those that have membership in a reputable association and/or are accredited by a professional organization. Homeowners are recommended to perform checks such as verifying license and insurance and checking business references prior to hiring a contractor to work on their house.

Spokane

Spokane (ⁱ/spoʊˈkæn/ spoh-kan)^[7] is a city in the state of Washington, in the northwestern United States. It is the seat of Spokane County, and the economic and cultural center of the Spokane Metropolitan Area, the Greater Spokane Area, and the Inland Northwest. It is located along the Spokane River west of the Rocky Mountain foothills in eastern Washington, 92 miles (148 km) south of the Canada–US border, approximately 20 miles (30 km) from the Washington–Idaho border, and 280 miles (450 km) east of Seattle along Interstate 90. The city, along with the whole Inland Northwest, is served by Spokane International Airport, 5 miles (8 km) west of downtown Spokane. According to the 2010 Census, Spokane had a population of 208,916, making it the second largest city in Washington and the 102nd largest city in the United States.

The first humans to live in the area, the Spokane people (their name meaning “children of the sun” in Salishan), arrived between 13,000 and 8,000 years ago, living off plentiful game. Known as the birthplace of Father’s Day, Spokane is officially nicknamed the “Lilac City”. David Thompson explored the area with the westward expansion and establishment of the North West Company‘s Spokane House in 1810. This trading post was the first long-term European settlement in Washington. Completion of the Northern Pacific Railway in 1881 brought settlers to the Spokane area, and that same year it was officially incorporated as a city with the name of “Spokan Falls”. In the late 19th century, gold and silver were discovered in the Inland Northwest. The local economy depended on mining, timber, and agriculture until the 1980s. Spokane hosted the first environmentally themed World’s Fair at Expo ’74.
