Exhibit 24

POWER OF ATTORNEY
For Executing Forms 3, 4 and 5


I appoint each of Eugene A. Gargaro, Jr., John R. Leekley,
and Barry J. Silverman, signing singly, my attorney-in-fact
to:

(1) execute and file with the Securities and Exchange
Commission on my behalf Forms 3, 4 or 5 as required
by Section 16(a) of the Securities Exchange Act of
1934 and the rules thereunder, and any amendments
thereto; and

(2) do anything in connection with the foregoing which
such attorney-in-fact may deem legally required by me or
in my best interest.

I grant to each such attorney-in-fact full power and authority
to do and perform any and every act and thing whatsoever
requisite, necessary or proper to be done in the exercise of
any of the rights and powers herein granted, as fully to all
intents and purposes as I could do if personally present,
with full power of substitution, hereby ratifying and
confirming all that such attorney-in-fact shall lawfully
do or cause to be done by virtue of this Power of Attorney
and the rights and powers herein granted.

I acknowledge that this Power of Attorney is granted by me
individually and as a Director, Trustee or Co-Trustee of
any charitable organization, foundation or trust holding
shares of Masco Corporation and which is subject to the
reporting requirements of Section 16(a) of the Securities
Exchange Act of 1934.

I acknowledge that the foregoing attorneys-in-fact, in
serving in such capacity at my request, are not assuming,
nor is Masco Corporation assuming, any of my
responsibilities to comply with Section 16 of the
Securities Exchange Act of 1934.

This Power of Attorney supersedes any Power of Attorney
executed by me, which is hereby revoked.  This Power of
Attorney shall remain in effect until I am no longer
required to file Forms 3, 4, and 5 with respect to my
holdings of and transactions in securities issued by
Masco Corporation, unless earlier revoked in writing by me.

This Power of Attorney is executed on October 27, 2003.
