                                                                    Exhibit 99.1

Trex Company First-Quarter Revenue Up 11%; 2004 Guidance Confirmed

    WINCHESTER, Va.--(BUSINESS WIRE)--April 20, 2004--Trex Company,
Inc. (NYSE: TWP), manufacturer of Trex(R) decking and railing, today
announced financial results for the first quarter ended March 31,
2004.
    Net sales for the first quarter of 2004 totaled $76.3 million
compared to $68.7 million for the first quarter of 2003. Net income
for the 2004 first quarter totaled $9.3 million, or $0.63 per diluted
share, compared to $10.1 million, or $0.69 per diluted share, for the
2003 first quarter.
    Chairman and Chief Executive Officer Robert Matheny commented,
"The year is off to a very strong start for Trex. Although our
expanded 'early buy' program, which now runs through April rather than
March, shifts sales from the first to the second quarter of 2004, we
are extremely pleased with the company's performance to date. In fact,
we exceeded our expectations for the first quarter and believe we are
on track to achieve the $240-$245 million in net sales that we
previously forecast for 2004, which would be an increase of 26%-28%
over 2003's net sales.
    "As expected, our first-quarter 2004 earnings were impacted by
increased brand-building activities and sales incentives related to
the promotion of our new Trex Accents(TM) and Trex Origins(TM) decking
products. We achieved our goal of bringing finished goods inventories
down by approximately 38%, although lower production levels compared
to last year's first quarter resulted in the unfavorable absorption of
fixed manufacturing overhead. Again, we are ahead of our expectations
and on target to achieve our previously announced net income guidance
for 2004 of $1.75-$1.80 per diluted share, a 22%-26% increase over
2003's net income."
    Mr. Matheny continued, "We view the first four months of the year
as the time to sell our product into distribution, with the ensuing
months dedicated to 'pull through' efforts and restocking the
distribution channel. Our distributors' response to our expanded early
buy program and our textured Trex Accents(TM) product line has been
excellent. Shipments of our new Trex Designer Series Railing(TM), a
line of high-style railing components that match our deck boards, have
begun to reach our dealers, and both our channel partners and
contractors have responded very favorably to the new product. Our
extensive brand building efforts are underway, with ad campaigns both
in print publications and on television, and are helping Trex gain
ever more recognition as the pre-eminent brand franchise in the
decking and related outdoor products market.
    "In addition, our recent agreement with The Home Depot, the
world's leading home improvement retailer, represents an exciting
opportunity for Trex to expand the company's distribution channels and
reach a whole new set of consumers and contractors, in the process
dramatically accelerating the conversion from wood to composite
decking. All in all, we expect 2004 to be a very successful year for
our company."
