                MASCO CORPORATION REPORTS SECOND QUARTER RESULTS

                          MASCO CORPORATION HIGHLIGHTS:

      SECOND QUARTER 2005

            -     Net sales from continuing operations increased nine percent to
                  a record $3.3 billion.

            -     Income from continuing operations was $274 million or $.64 per
                  common share.

            -     The Company returned $229 million to shareholders through
                  share repurchases and dividends.

            -     The Company issued $500 million of fixed-rate 4.80% notes due
                  2015 and had over $1.6 billion in cash and marketable
                  securities at June 30, 2005.

      Taylor, Michigan (August 2, 2005) - Masco Corporation (NYSE: MAS) today
reported that net sales from continuing operations for the quarter ended June
30, 2005 increased nine percent to a record $3.3 billion compared with $3.1
billion for the second quarter of 2004.

      Income from continuing operations for the second quarter of 2005 was $274
million or $.64 per common share compared with $294 million or $.65 per common
share for the comparable period of 2004. Results for the second quarter of 2005
benefited from other income, principally net gains from financial investments,
of $.04 per common share, partially offset by realized currency transaction
losses of $.02 per common share. The second quarter of 2004 benefited from $.03
per common share of other income, principally net gains from financial
investments and other non-operating assets, as well as $.01 per common share of
income related to insurance proceeds from the Behr litigation settlement and
$.01 per common share of realized currency transaction gains.

      The Company's 2005 first half results were adversely affected by
increases in commodity, energy and freight costs, which have not been totally
recovered due, in part, to the lag in implementing selling price increases to
customers, as well as product mix. Second quarter 2005 sales and earnings,
however, were better-than-expected due to the strong new construction market as
well as an improvement in key retailer sales.



      The Company previously announced, in the first quarter of 2004, the
planned disposition of several European businesses that are not core to the
Company's long-term growth strategy. Net income for the second quarter of 2005
did not include any net income (loss) related to discontinued operations, since
the Company completed the disposition process in the first quarter of 2005. The
second quarter of 2004 results include after-tax income from discontinued
operations of $11 million, and an additional after-tax charge aggregating $44
million ($.10 per common share) for those businesses that were expected to be
divested at a loss, both of which are included in discontinued operations.
Including the operating results of these discontinued operations and the charge
for certain of these businesses, net income for the 2004 second quarter was $261
million or $.58 per common share.

      The Company is committed to its strategy of value creation and continues
to be focused on the simplification of its business model, cash flow generation,
improvement in return on invested capital and the return of cash to shareholders
through share repurchases and dividends.

      Consistent with this strategy, the Company is pursuing a variety of
initiatives to offset cost increases and increase operating profit, including
sourcing programs, the restructuring of certain of its businesses (including
consolidations), manufacturing rationalization, headcount reductions and other
profit improvement programs. As previously disclosed, the Company believes these
initiatives will reduce annual costs by $200 million by the end of 2007. Costs
and charges related to the acceleration of these profit improvement programs,
when combined with recent additional energy-related and commodity cost increases
and the adverse effect of changes in currency values, are expected to result in
the Company's full-year 2005 earnings from continuing operations being closer to
$2.30 per common share than the previous guidance of approximately $2.40 per
common share. Implementing these initiatives should improve the Company's
earnings outlook for 2006 and beyond.

      Based on current business trends, the Company anticipates that third
quarter 2005 earnings from continuing operations will be in the range of $.60 to
$.64 per common share compared with third quarter 2004 earnings from continuing
operations of $.64 per common share.

      windows were particularly strong in the quarter.

- -     Key retailer sales from continuing operations improved significantly from
      recent quarters to an increase of 10 percent in the 2005 second quarter
      compared with a two percent decrease in the first quarter of 2005 and a 14
      percent increase in the second quarter of 2004.

SECOND QUARTER 2005 (CONTINUED)

- -     Earnings from continuing operations were $.64 per common share compared
      with the Company's guidance of $.58 to $.62 per common share and compared
      with $.65 per common share for the 2004 second quarter.

- -     Results for the second quarter of 2005 benefited from other income of $.04
      per common share, principally net gains from financial investments. The
      second quarter of 2004 included $.03 per common share of other income,
      principally net gains from financial investments and other non-operating
      assets, as well as $.01 per common share of income related to insurance
      proceeds from the Behr litigation settlement.

- -     Results for the second quarter of 2005 include realized currency
      transaction losses of $14 million ($.02 per common share, after tax)
      compared with $6 million of realized currency transaction gains ($.01 per
      common share, after tax) in the second quarter of 2004.

- -     The Company previously announced, in the first quarter of 2004, the
      planned disposition of several European businesses that are not core to
      the Company's long-term growth strategy. Net income for the second quarter
      of 2005 was $274 million or $.64 per common share and did not include any
      net income (loss) related to discontinued operations, since the Company
      completed the disposition process in the first quarter of 2005. The second
      quarter of 2004 results include after-tax income from discontinued
      operations of $11 million, and an additional after-tax charge aggregating
      $44 million ($.10 per common share) for those businesses that were
      expected to be divested at a loss, both of which are included in
      discontinued operations. Including the operating results of these
      discontinued operations and the charge for certain of these businesses,
      net income for the 2004 second quarter was $261 million or $.58 per common
      share. Total net proceeds for the dispositions completed in 2005 and 2004
      aggregated $281 million.

- -     The Company's 2005 second quarter results benefited from strong organic
      sales growth, partially offset by continued increases in commodity, energy
      and freight costs, which have not been fully recovered due, in part, to
      the lag in implementing selling price increases to customers.

SECOND QUARTER 2005 (CONTINUED)

- -     Gross margins were 29.4 percent in the 2005 second quarter compared with
      31.8 percent in the second quarter of 2004. Operating profit margins, as
      reported, were 14.1 percent in the second quarter of 2005 compared with
      15.6 percent in the second quarter of 2004. Excluding the pre-tax income
      regarding the litigation settlement of $3 million and $7 million in 2005
      and 2004, respectively, operating profit margins were 14.0 percent in the
      second quarter of 2005 compared with 15.4 percent in the second quarter of
      2004. Operating profit margins in the second quarter of 2005 were
      adversely impacted by increases in certain operating expenses, including
      increased commodity, energy and freight costs, as well as product mix.

- -     SG&A expenses as a percent of sales, including general corporate expense,
      were 15.4 percent in the second quarter of 2005 compared with 16.5 percent

      compared with 54 days a year ago.

- -     Accounts payable days were 38 days at both June 30, 2005 and 2004.

- -     Working capital at June 30, 2005 (defined as accounts receivable and

      twelve months' sales from 19.2 percent a year earlier.

- -     The Company's tax rate was 35.4 percent for the second quarter of 2005
      compared with 35.8 percent for the comparable period of the prior year.

      should approximate 35 percent.

      invested capital (as reported) was 11.7 percent and 12.2 percent,

                        BUSINESS AND FINANCIAL HIGHLIGHTS

FULL-YEAR OUTLOOK

- -     The Company remains committed to its strategy of value creation and is
      focused on the simplification of its business model, cash flow
      generation, improvement in return on invested capital and the return of
      cash to shareholders through share repurchases and dividends.

- -     Consistent with this strategy, the Company is pursuing a variety of
      initiatives to increase operating income, including sourcing programs, the
      restructuring of certain of its businesses (including consolidations),
      manufacturing rationalization, headcount reductions and other profit
      improvement programs. As previously disclosed, the Company believes these
      initiatives will reduce annual costs by $200 million by the end of 2007.
      Costs and charges related to the acceleration of these profit improvement
      programs, when combined with recent additional energy-related and
      commodity cost increases and the adverse effect of changes in currency
      values, are expected to result in the Company's full-year 2005 earnings
      from continuing operations being closer to $2.30 per common share than the
      previous guidance of the low end of a range of $2.40 to $2.50 per common
      share. Implementing these initiatives should improve the Company's
      earnings outlook for 2006 and beyond.

- -     Based on current business trends, the Company anticipates that third
      quarter 2005 earnings from continuing operations will be in the range of
      $.60 to $.64 per common share compared with third quarter 2004 earnings
      from continuing operations of $.64 per common share.

- -     The Company's guidance is based on no additional share repurchases beyond
      the 18 million common shares repurchased in the first half of 2005, modest
      margin improvement in the second half of 2005 compared with the first half
      of 2005, reflecting selling price increases further offsetting
      higher commodity costs, and anticipated income from financial investments,
      and excludes any other items.

      Statements contained herein may include certain forward-looking statements
regarding Masco's future sales, earnings growth potential and other

factors over which management has no control. The Company 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. Non-GAAP
performance measures and ratios should be viewed in addition to, and not as an
alternative for, the Company's reported results under accounting principles
generally accepted in the United States. Additional information about our
products, markets and conditions, which could affect the Company's future
performance, is contained in the Company's filings with the Securities and

                     NOTES TO CONDENSED STATEMENTS OF INCOME
                            2005 & 2004 - BY QUARTER

NOTES:

- -     Operating results exclude 2004 planned dispositions as well as operations
      which were sold in 2005 and 2004, all of which were treated as
      discontinued operations in accordance with SFAS No. 144, "Accounting for
      the Impairment or Disposal of Long-Lived Assets."

- -     Income from discontinued operations in the first quarter of 2005 includes
      an $11 million pre-tax gain, net ($.04 per common share, after tax) from
      the sale of two businesses.

- -     Operating results for the fourth quarter of 2004 reflect a non-cash,
      pre-tax charge for goodwill impairment of $168 million ($141 million or
      $.31 per common share, after tax).

- -     Income from discontinued operations in the third quarter of 2004 includes
      a $108 million pre-tax gain, net ($93 million or $.21 per common share,
      after tax) from the sale of two businesses.

- -     Income (loss) from discontinued operations in the first, second and third
      quarters of 2004 includes pre-tax impairment charges of $64 million ($76
      million or $.16 per common share, after tax), $44 million ($44 million or
      $.10 per common share, after tax) and $31 million ($31 million or $.07 per
      common share, after tax), respectively.

- -     Per common share amounts for the four quarters of 2004 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.

NOTES:

The Company presents information comparing results from one period to another
excluding the results of businesses acquired 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 period. The Company presents this information in order to assess
how the underlying businesses performed in local currencies before taking into
account currency fluctuations.

NOTES:

The unusual relationship between income tax benefit and income before income
taxes (including the gain on the disposition of businesses) for the six months
ended June 30, 2005 results from the gain requiring no current tax expense and
the reversal of deferred tax liabilities of the discontinued operations which
are no longer expected to be incurred. The after-tax charge for the impairment
of assets held for sale was $76 million in the first quarter of 2004, including
$12 million for the expensing of deferred tax assets of the discontinued
operations, and $44 million in the second quarter of 2004.

The information for discontinued operations is for the period prior to the
respective dates of disposition.
