                                                                    Exhibit 99.1

    Trex Company Reports 57% Increase in First Quarter Net Income

    WINCHESTER, Va.--(BUSINESS WIRE)--April 23, 2003--Trex Company,
Inc. (NYSE: TWP), manufacturer of Trex(R) decking and railing, today
announced financial results for the first quarter ended March 31,
2003.
    Net sales for the quarter were a record $68.7 million, which
represented an increase of 32% over the $52.0 million reported for the
first quarter of 2002. Net income for the quarter increased 57% to
$10.1 million from the $6.4 million recorded in the first quarter of
2002. On a fully diluted per share basis, net income for the quarter
was $0.69 per share versus $0.45 per share in 2002.
    Trex Company President Robert Matheny commented, "Our goal at Trex
has always been to create a better product, tell people about it, and
make it easy to buy. During the first quarter of 2003, progress on all
three fronts was reflected in our strong financial performance. Demand
for our product was strong during the first quarter early buy period
and our two new production lines ran at full capacity. We are in the
process of installing two additional manufacturing lines (bringing the
total to nineteen), with start-ups scheduled for this summer. This
will bring our annual revenue generating capacity to above $250
million. In addition, this year we are instituting the most compelling
advertising and marketing program in our history, all aimed at
defining the decking category, Trex. Finally, we have strengthened our
sales force, are enlarging our dealer base, and are significantly
expanding our TrexPro(TM) initiative, which matches homeowners
interested in Trex decking and railing with experienced contractors in
their area."
    "Based on these developments and trends, we expect that 2003's
second quarter revenue will be between $55 and $57 million, resulting
in earnings of $0.42 to $0.44 per fully diluted share. In the second
quarter of 2003, SG&A expenses will be up significantly over those of
2002's second quarter, primarily to support our extensive marketing
communication program. For the full year 2003, our expectation is that
revenue will exceed $200 million, with earnings of between $1.63 to
$1.66 per fully diluted share. Previous guidance for gross profit and
SG&A as a percent of revenue remains the same.
