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:
- 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 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”.
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, 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, and a $48 billion industry in Canada.[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.
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.
Corry is a city in northwestern Pennsylvania in the United States. With a population of 6,605 at the 2010 United States Census, it is the second largest city in Erie County. Corry is a part of the Erie, PA Metropolitan Statistical Area. The city became famous in the late-19th and early-20th centuries for being the manufacturer of Climax locomotives.
Erie County was formed from parts of Allegheny County on March 12, 1800. On May 27, 1861, tracks owned by the Atlantic and Great Western Railroad intersected with those of the Sunbury and Erie Railroad and was called the “Atlantic and Erie Junction”. Land at the junction was owned by Hiram Cory, who sold a portion to the Atlantic and Great Western in October 1861. The railroad built a ticket office at the junction and named it for Cory, but through a misspelling it became Corry.
The combination of railroad growth and the discovery of oil in nearby Titusville contributed greatly to Corry’s development. This boomtown was chartered as a borough in 1863 and designated as a city in 1866. Industry has played a big part in Corry’s growth, and the Corry Area Historical Society maintains a museum where one of the Climax locomotives (the steam engine used in logging operations that brought fame to Corry) is on display.
