Ladies and Gentlemen:

     We have acted as counsel to Matrix Service Company, a Delaware
corporation (the "Company") in connection with the Company's Form S-8
relating to the registration under the Securities act, of 1933, as
amended, of the issuance of up to an additional 550,000 shares (the
"Shares") of common stock, par value $0.01 per share (the "Common Stock"),
pursuant to the Matrix Service Company 1991 Stock Option Plan, as amended
(the "Plan").

     As the basis for the opinions hereinafter expressed, we have examined
such corporate records and documents, certificates of corporate and public
officials and such other instruments as we have deemed necessary for the
purposes of the opinions contained herein.  As to all matters of fact
material to such opinions, we have relied upon the representations of
officers of the Company.  We have assumed the genuineness of all signatures,
the authenticity of all documents submitted to us as originals, and the
conformity with the original documents of all documents submitted to us as
copies.

     Based upon the foregoing and having due regard for such legal
considerations as we deem relevant, we are of the opinion that the Shares
have been duly authorized, and that the Shares, when issued in accordance
with the terms of the Plan, will be validly issued, fully paid and
nonassessable.

     We hereby consent to the inclusion of this opinion as an exhibit to the
Registration Statement.

                               Very truly yours,


                               ANDREWS & KURTH LLP
