                           MASCO CORPORATION REPORTS
                   RECORD SECOND QUARTER SALES AND EARNINGS,
                    UPDATES EARNINGS GUIDANCE AND ANNOUNCES
                     INTENT TO INCREASE QUARTERLY DIVIDEND




         Taylor, Michigan (August 6, 2003) -- Masco Corporation (NYSE:MAS)
today reported that net sales for the second quarter ended June 30, 2003, aided
by acquisitions, increased 20 percent to a record $2.8 billion, compared with
$2.3 billion for the second quarter of 2002. Net income for the quarter
increased seven percent to a record $229.6 million compared with $214.3 million
for the 2002 second quarter. Earnings per common share also increased seven
percent to $.46 compared with $.43 per common share for the 2002 second quarter.

         Although a record quarter, operating profit margins in 2003 have been
negatively impacted by sales being somewhat lower than expected due to adverse
weather conditions in certain markets, by higher energy, insurance and pension
costs and by a non-cash charge resulting from a system failure during efforts to
convert to a new business system at one of the Company's European operations.

         Masco Chairman and CEO Richard A. Manoogian commented, "Given the
current economic environment, we are pleased with our performance in the second
quarter and expect the second half of 2003 to be even stronger than the first
half. If present positive sales and economic trends continue, the Company
believes that third quarter earnings per common share should approximate $.48 to
$.51 and continues to expect to achieve record sales and earnings for 2003 with
full-year earnings in a range of $1.68 to $1.72 per common share, modestly
higher than the Company's previous guidance."







         Masco also announced that it is the present intent of the Company's
Board of Directors to increase the quarterly dividend in the fourth quarter by
14 percent from $.14 to $.16 per common share. The new quarterly dividend
reflects the Company's favorable long-term outlook, strong balance sheet and
cash flow and recent tax law changes, and would make this the 45th consecutive
year in which dividends have been increased.

         Headquartered in Taylor, Michigan, Masco Corporation is one of the
world's leading manufacturers of home improvement and building products as well
as a leading provider of services that include the installation of insulation
and other building products.

earnings is scheduled for Wednesday, August 6, 2003 at 11:00 a.m. ET.

                                MASCO CORPORATION
                        BUSINESS AND FINANCIAL HIGHLIGHTS


The Company reports its financial results in accordance with generally accepted
accounting principles (GAAP). However, management believes that certain non-GAAP
performance measures and ratios, used in managing the business, may provide
users of this financial information with additional meaningful comparisons
between current results and results in prior periods. See the attached tables
for supplemental financial data and the corresponding reconciliations to GAAP
financial measures for the three months ended June 30, 2003 and June 30, 2002,
as well as for the year 2002. Non-GAAP financial measures should be viewed in
addition to, and not as an alternative for, the Company's reported results
prepared in accordance with GAAP.



SECOND QUARTER 2003

- -    Net sales, aided by acquisitions, were a record $2.8 billion, increasing 20
     percent over 2002 second quarter sales, with North American sales
     increasing 15 percent and International sales increasing 54 percent.
     Stronger sales to non-retail customers, sales of acquired companies
     (particularly Service Partners in our Installation Group and Hansgrohe AG
     in our International Plumbing Products Group) and the favorable impact of
     foreign currencies more than offset slower sales growth with certain of the
     Company's retail customers.

- -    Excluding acquisitions and divestitures, second quarter 2003 consolidated
     net sales increased seven percent compared with second quarter 2002 sales;
     North American sales increased five percent and International sales
     increased 18 percent. In local currencies, International sales decreased
     one percent compared with 2002.

- -    Given the second quarter economic challenges, including adverse weather
     conditions in certain markets and higher energy costs reducing consumer
     disposable income, the Company is pleased with it's internal sales growth
     rate of seven percent during the quarter. This rate of organic growth
     (which includes the benefit of higher foreign currencies) compares
     favorably with most of our peer group.

                        BUSINESS AND FINANCIAL HIGHLIGHTS

SECOND QUARTER 2003 (CONTINUED)

- -    The Company reported net income of $229.6 million or $.46 per common share
     (both records for any quarter in the Company's history), modestly above the
     Company's previous earnings guidance range of $.43 to $.45 per common
     share.

- -    In the second quarter of 2003, the Company recorded a non-cash pre-tax
     charge which reduced operating profit by approximately $23 million ($.03
     per common share, after tax) with respect to a European business unit in
     the Decorative Architectural Products segment. The charge resulted from
     business system failures at the unit during efforts to convert to a new
     business system in 2001 and 2002, and the unit management's inadequate
     response to the problem. The failures primarily impacted the accurate
     recognition of cost of sales for the operation's more than 20,000 SKU's of
     product manufactured and supplied by its subsidiaries and third parties in
     Asia, with a corresponding misstatement of certain balance sheet accounts.
     The Company has implemented corrective action to prevent this situation
     from occurring at the unit in the future, including replacement of members
     of the unit's senior management. While this unit remains profitable,
     nevertheless the Company is continuing to analyze the business unit's
     profitability and cash flow prospects and to determine if any impairment of
     assets exists, including a portion of the goodwill.

- -    The second quarter earnings charge of $.03 per common share, as mentioned
     above, was partially offset by net gains of $.02 per common share from the
     sale of marketable securities and other investments.

- -    Key retailer sales growth in the second quarter of 2003 increased six
     percent, compared with a four percent increase in the first quarter of
     2003. Combined sales to Home Depot, Lowe's and Wal-Mart increased by
     approximately six percent in the 2003 second quarter compared with a three
     percent increase in the first quarter of 2003 and an 11 percent increase in
     the 2002 second quarter.

                        BUSINESS AND FINANCIAL HIGHLIGHTS

SECOND QUARTER 2003 (CONTINUED)

- -    Sales by segment in the 2003 second quarter versus the 2002 second quarter
     were:

     -   Cabinets and Related Products sales were up nine percent;

     -   Plumbing Products sales were up 31 percent;

     -   Installation and Other Services sales were up 47 percent;

     -   Decorative Architectural Products sales were up seven percent; and

     -   Other Specialty Products sales increased 14 percent.

Particularly strong product sales in the quarter included assembled cabinets at
retail, installed sales of non-insulation products, paints and stains and vinyl
windows.

- -    Gross margins were 30.6 percent in the 2003 second quarter compared with
     33.0 percent in 2002.

- -    Operating profit margins decreased to 14.0 percent compared with 17.1
     percent in the second quarter of 2002.

- -    Excluding the pre-tax charge related to a European business unit, gross
     margins would have been 31.4 percent and operating profit margins would
     have been 14.8 percent.

                        BUSINESS AND FINANCIAL HIGHLIGHTS

SECOND QUARTER 2003 (CONTINUED)

- -    Second quarter 2003 gross margins and operating margins were adversely
     affected by:

     -   Increased energy, insurance and pension costs;

     -   Higher promotion and display costs;

     -   Weather conditions in certain markets;

     -   Higher foreign currencies resulting in increased international sales
         which have lower margins;

     -   Product mix and relatively higher sales in product segments with
         somewhat lower margins; and

     -   Recently acquired companies with lower operating margins.

- -    SG&A expense as a percent of sales was 16.7 percent compared with 16.0
     percent in the 2002 second quarter, reflecting increased promotional
     selling expenses and increased pension and insurance costs.

- -    General corporate expense was 1.0 percent of sales in the second quarter of
     both 2003 and 2002.

- -    Inventory days were 58 days at June 30, 2003 compared with 60 days at June
     30, 2002.

- -    Accounts receivable days at the end of the second quarter were 53 days
     compared with 57 days a year ago.

- -    Accounts payable days at the end of the second quarter improved to 32 days
     from 26 days a year ago, as we continue to negotiate more favorable
     supplier terms.

- -    Working capital at June 30, 2003 (defined as accounts receivable and
     inventories less accounts payable) improved to 22.0 percent of the last
     twelve months of sales from 23.4 percent a year earlier.

                        BUSINESS AND FINANCIAL HIGHLIGHTS

SECOND QUARTER 2003 (CONTINUED)

- -    For the twelve months ended June 30, 2003, operating profit return on net
     operating assets, (as reconciled) declined to 16.9 percent for the 2003
     second quarter compared with 17.6 percent for the comparable period through
     June 30, 2002, reflecting acquisitions in the second half of 2002.

- -    For the twelve months ended June 30, 2003, return on invested capital (as
     reconciled) increased to 11.1 percent compared to 10.8 percent for the
     comparable period through June 30, 2002.

- -    The Company's tax rate was 34.8 percent in the second quarter of 2003
     compared with 34.0 percent for the comparable period of the prior year. The
     rate increase is principally the result of recent acquisitions increasing
     the proportion of domestic income, which is generally taxed at higher rates
     than foreign income. The Company anticipates that its tax rate for all of
     2003 will approximate 35 percent.

- -    At the end of the quarter, the Company had a strong balance sheet, with
     approximately $1.1 billion in cash and marketable securities and $2 billion
     in unused bank lines.

- -    Debt as a percent of total capitalization was 47 percent at both June 30,
     2003 and March 31, 2003.

- -    The Company repurchased approximately nine million common shares during the
     second quarter of 2003. Through June 30, approximately 23 million shares
     have been repurchased in 2003, including approximately 2 million shares for
     long-term incentive compensation plans. The Company currently has
     approximately 28 million shares remaining under its share repurchase
     authorization.

- -    The Company announced its Board of Directors' intent to increase the
     quarterly dividend in the fourth quarter by 14 percent (a larger percentage
     increase than in recent years) from $.14 to $.16 per common share. The new
     quarterly dividend reflects the Company's favorable long-term outlook,
     strong balance sheet and cash flow and recent tax law changes, and would
     make this the 45th consecutive year in which dividends have been increased.

- -    As previously announced, beginning January 1, 2003, the Company began

                        BUSINESS AND FINANCIAL HIGHLIGHTS

SECOND QUARTER 2003 (CONCLUDED)

- -    The weighted average diluted shares outstanding for the quarter were 498.5
     million (519.6 million for the quarter ended March 31, 2003). Average
     diluted shares outstanding at the end of the quarter, taking into account
     the reduction for shares repurchased and not included as a reduction in the
     quarter would have been approximately 494 million. Contingently issuable
     shares, related to share price guarantees, utilized in the calculation of
     earnings per common share in the second quarter were based on a quarter-end
     average share price of $24.19. Such contingently issuable shares declined
     from 19.6 million shares at March 31, 2003 to 7.8 million shares at June
     30, 2003.

- -    During the quarter, the Company completed the sale of its 42 percent equity
     interest in Emco Limited for cash proceeds of approximately $75 million.
     The sale resulted in a pre-tax gain of $4.8 million.

- -    In early July, the Company announced that it had signed a letter of intent
     providing for the purchase by The Black & Decker Corporation of Masco's
     Baldwin Hardware and Weiser Lock businesses. Baldwin and Weiser had
     combined 2002 net sales of approximately $250 million. The transaction is
     expected to close late in 2003 and is subject to final negotiation of a
     definitive purchase agreement, necessary regulatory clearances and approval
     from the Boards of Directors of both Companies. The Company expects to
     realize a gain on this transaction.

FULL-YEAR OUTLOOK

- -    The Company currently expects the second half of 2003 to be even stronger
     than the first half. If present positive sales and economic trends
     continue, the Company believes that third quarter earnings per common share
     should approximate a record $.48 to $.51 and continues to expect to achieve
     record sales and earnings for 2003 with full-year earnings in a range of
     $1.68 to $1.72 per common share, modestly higher than the Company's
     previous guidance.


Statements contained herein may include certain forward-looking statements
regarding Masco's future sales, earnings growth potential and other
developments. Actual results may vary materially because of external factors
such as interest rate fluctuations, changes in consumer spending and other
factors over which management has no control. Additional information about our
products, markets and conditions, which could affect our future performance, is
contained in the Company's filings with the Securities and Exchange Commission
and is available on Masco's website at www.masco.com.

NOTES:

- -    In the second quarter of 2003, the Company recorded a non-cash pre-tax
     charge of approximately $23 million ($.03 per common share, after tax)
     related to a business system failure at a European business unit in the
     Decorative Architectural Products segment. The charge resulted from system
     failures at the unit and the unit managements' inadequate response to these
     failures during efforts to convert to a new business system in 2001 and
     2002. The failures primarily impacted accurate recognition of cost of sales
     associated with over 20,000 sku's at the business unit with a corresponding
     misstatement of certain balance sheet accounts.

- -    Due to the unexpected passing of the Company's President and Chief
     Operating Officer, certain benefits were accelerated and expensed in the
     first quarter of 2003. A portion of the benefit liability (related to an
     investment in the Company's common stock) fluctuates based on the market
     price of Company common stock. In the second quarter of 2003, the Company
     recognized income relating to this liability as the obligation is marked to
     market, based on the Company's stock price, at the end of each reporting
     period.

- -    Data for 2002 exclude a first quarter, non-cash goodwill accounting change
     charge effective January 1, 2002 of $.19 per common share. In addition, per
     common share amounts for the four quarters do not total to the per common
     share amount for the year due to the timing of capital stock transactions
     and the effect of contingently issuable shares.

- -    Earnings per common share in the third quarter of 2002 include a $.20
     charge for a litigation settlement.

- -    Earnings in the fourth quarter of 2002 include approximately $35 million of
     income related to insurance proceeds and the reversal of a charge related
     to the planned disposition of a business and approximately $36 million of
     charges related to non-operating asset impairments and realized losses on
     marketable securities.

- -    Excluding the effect of unusual items (principally the Behr litigation
     settlement charge, net and a non-cash accounting change charge related to
     goodwill impairment), net income for the year 2002 was $780 million or
     $1.52 per common share (see page 10 for the GAAP reconciliation).

NOTES:

- -    Operating profit margins above are before general corporate expense, income
     related to a litigation settlement (which relates to the Decorative
     Architectural Products segment) and accelerated benefit (income) expense.

- -    In the second quarter of 2003, the Company recorded a non-cash pre-tax
     charge of approximately $23 million ($.03 per common share, after tax)
     related to a business system failure at a European business unit in the
     Decorative Architectural Products segment.

- -    Due to the unexpected passing of the Company's President and Chief
     Operating Officer, certain benefits were accelerated and expensed in the
     first quarter of 2003. In the second quarter of 2003, the Company
     recognized income relating to this liability as the obligation is marked to
     market, based on the Company's stock price, at the end of each reporting
     period.

NOTES:

(A)  In the second quarter of 2003, the Company recorded a non-cash pre-tax
     charge of approximately $23 million ($.03 per common share, after tax)
     related to a business system failure at a European business unit in the
     Decorative Architectural Products segment.

(B)  The Company owns 64% of Hansgrohe AG; this line is the reduction of income
     to reflect the minority interest.

(C)  Due to the unexpected passing of the Company's President and Chief
     Operating Officer, certain benefits were accelerated and expensed in the
     first quarter of 2003. In the second quarter of 2003, the Company
     recognized income relating to this liability as the obligation is marked to
     market, based on the Company's stock price, at the end of each reporting
     period.

NOTES:

(A)  In the second quarter of 2003, the Company recorded a non-cash pre-tax
     charge of approximately $23 million ($.03 per common share, after tax)
     related to a business system failure at a European business unit in the
     Decorative Architectural Products segment.

(B)  The first six months of 2003 includes $13.5 million of income related to
     insurance proceeds for a litigation settlement regarding the Company's
     subsidiary, Behr Process Corporation.

(C)  The Company owns 64% of Hansgrohe AG; this line is the reduction of income
     to reflect the minority interest.

(D)  Due to the unexpected passing of the Company's President and Chief
     Operating Officer, certain benefits were accelerated and expensed in the
     first quarter of 2003. In the second quarter of 2003, the Company
     recognized income relating to this liability as the obligation is marked to
     market, based on the Company's stock price, at the end of each reporting
     period.

The Company presents information comparing results from one period to another
excluding the results of businesses acquired or disposed of in order to assess
the performance of the underlying businesses and to assess to what extent
acquisitions are driving growth.

The Company also presents information comparing results of International
operations from one period to another using constant exchange rates. To present
this information, current period results for foreign entities are converted into
U.S. dollars using the prior period's exchange rates, rather than exchange rates
for the current year. The Company presents this information in order to assess
how the underlying businesses performed before taking into account currency
fluctuations.
