How House Construction Works
HVAC - Once the underlayment is down, the HVAC contractor will install the heating and air conditioning unit (aka the furnace), the vents and all duct work. If this had been a two-story home or a home built on a slab, the HVAC people might have had to install some ductwork in the walls or between floors. However, in a single-story home on a crawl space or basement, the furnace and all ducting can go in very late in the process because everything goes under the house.
Finish electrical - The electrician will return and install all light fixtures, wall outlets, switches and cover plates.
Kitchen and bathroom cabinets and counters - The cabinet company will install kitchen and bathroom cabinets. They are simply aligned on the wall and screwed into the wall studs. Countertops are screwed on top of the cabinets.
Finish plumbing - Once the cabinets are in, the plumber will return and install sinks, toilets and faucets. The plumber will also install the water heater if it was not installed during rough plumbing.
Installation of well and septic system or hook-up to city water and sewer - Depending on where the house is located, it will either have a private well and septic system or it will hook up to municipal water and sewer lines. If a private well and septic tank are needed, the contractor will bring in a well-drilling subcontractor and a septic-tank subcontractor. Otherwise, the contractor will call someone (either the municipality or a subcontractor) to extend the municipal lines to the house. The plumber will hook up the water and sewer lines.
Wall trim - Once the cabinets are in, the interior doors are installed and the molding around the doors, windows and baseboards goes in.
Paint - Once the molding is on, it is time to paint and wallpaper the interior of the house.
Carpeting and tile - Once the paint is done, carpet and tile goes down.
The final punch list
- At this point, the builder inspects the house, noting any problems. All problems
are tabulated on a punch list. The different contractors return to fix all of the
The next time you walk into a house
or start poking around under it, I hope you do so with a much better understanding
and appreciation for everything that goes into making it work!
