About the Builder - Town
& Country Homes
In
1996 Town & Country Homes built nearly 1,500 homes. This achievement
didn’t come without problems. The major problem was the nearly $1
million spent on warranty callbacks. In that same year, Town & Country
had an average of 2,376 homes in warranty monthly, writing an average of
3,000 work orders per month that year.
1997 found Town & Country writing only
1,486 work orders monthly, a 50% reduction. A major factor in this
reduction was how Town & Country Homes approached warranty issues,
finding the real cause , fixing it, and ending repeat visits. During this
time Town & Country Homes’ specifications and contract were revised
to include draftstopping , sealing penetrations, and drainage plane.
Town & Country Homes also brought
Joseph Lstiburek, Building Science Corporation Principal, into the picture
who introduced them to the Department of Energy’s "Building
America" program. A community was designed using details that would
make these homes at least 30% more energy efficient then comparably sized
homes built the standard way. A major difference was "O.V.E."
framing. This means using less lumber and stacking framing for greater
structural integrity. The first advantage was 2x6 framing allowed R-19
insulation. Less wood and more insulation definitely eliminated comfort
complaints. Secondly, less lumber means less contact points with drywall.
Structural movement when the wood dries out and settles is the largest
contributor to drywall cracks. This concept alone reduced drywall repair
costs to $ 150 per home from $ 1200 to $ 1500 per home. In fact, some of
their smaller homes actually have "zero item" drywall
inspections after 11-months.
Town & Country Homes has taken most of
these specifications and built virtually every house since this community
using these concepts.
Each Town & Country Homes community is
a little better than the last. The work orders clearly indicate a
pattern.
In 1998 Town & Country Homes averaged
1,710 homes in warranty monthly, writing 1,058 work orders. This
represents another 29% reduction.
1999 shows Town & Country Homes writing
only 884 work orders monthly. This while they still have 1,477 homes in
warranty per month. This is another 16% decrease since 1998. Thus far in
2000, Town & Country Homes is averaging around 686 work orders each
month, another 22% reduction.
What Town & Country Homes has done was
not simply put the burden of repair on the individual contractors. They
have changed how they are building homes. Town & Country is building
"Durable Homes" that don't require excessive amounts of time or
expense to service after closing.
Design Philosophy and
Application
Town
& Country has changed how they build homes. They have taken the high
road and raised the bar. They are building more durable homes that neither
they nor their trades have to spend excessive amounts of time or expense
to service after closing. This just so happens to have a direct
relationship with the bottom line AND satisfied customers.
