Ladies and Gentlemen:

     We have acted as counsel to Integrated Electrical Services, Inc., a
Delaware corporation (the "Company") and are delivering this opinion in
connection with the Company's Registration Statement on Form S-4 (the
"Registration Statement") relating to the registration under the Securities Act
of 1933, as amended (the "Securities Act"), of the offer by the Company to
exchange up to $125,000,000 aggregate principal amount of its 9 3/8% Senior
Subordinated Notes Due 2009, Series D (the "Exchange Notes") for its existing
9 3/8% Senior Subordinated Notes Due 2009, Series C (the "Existing Notes"). The
Exchange Notes are proposed to be issued in accordance with the provisions of
the indenture (the "Indenture"), dated as of May 29, 2001, between the Company,
the guarantors named therein (the "Guarantors") and State Street Bank and Trust
Company, as Trustee.

     In arriving at the opinions expressed below, we have examined the
Registration Statement, the Prospectus contained therein, the Indenture which is
filed as an exhibit to the Registration Statement, and the originals or copies
certified or otherwise identified to our satisfaction of such other instruments
and other certificates of public officials and officers and representatives of
the Company. In such examination, we have assumed and have not verified (i) that
the signatures on all documents that we have examined are genuine, (ii) the
authenticity of all documents submitted to us as originals, (iii) the conformity
with the authentic originals of all documents submitted to us as certified,
photostatic or faxed copies, and (iv) that all documents in respect of which
forms were filed with the Securities and Exchange Commission as exhibits to the
Registration Statement will conform in all material respects to the forms
thereof that we have examined. In addition, as the basis for the opinion
hereinafter expressed, we have examined such statutes, regulations, corporate
records and documents, certificates of corporate and public officials and other
instruments as we have deemed necessary or advisable for the purposes of this
opinion.

     Based upon the foregoing, having due regard for such legal considerations
as we deem relevant, we are of the opinion that the Exchange Notes and the
guarantee of each of the Guarantors (the "Guarantees"), (a) when the Notes have
been exchanged in the manner described in the Registration Statement, (b) when
the Exchange Notes have been duly executed, authenticated, issued and delivered
in accordance with the terms of the Indenture, (c) when the Indenture has been
duly qualified under the Trust Indenture Act of 1939, as amended, and (d) when
applicable provisions of "blue sky" laws have been complied with, will
constitute valid and binding obligations of the Company and the Guarantors, as
applicable, enforceable against the Company and the Guarantors, as applicable,
in accordance with their terms, under the laws of the State of New York which
are expressed to govern the same, except as the enforcement thereof may be
limited by (a) bankruptcy, insolvency, reorganization, moratorium (including,
without limitation, all laws relating to fraudulent transfers), (b) other
similar laws relating to or affecting enforcement of creditors' rights
generally, (c) general principles of equity (regardless of whether enforcement
is considered in a proceeding in equity or at law) and (d) limitations on the
waiver of rights under usury laws, and will be entitled to the benefits of the
Indenture.

     This opinion is limited in all respects to the laws of the State of Texas,
the State of New York and the Delaware General Corporation Law. We express no
opinion as to, and for the purposes of the opinions set forth herein, we have
conducted no investigation of, and do not purport to be experts on, any other
laws. With respect to each Guarantor which was not organized under the laws of
the State of Texas or the State of Delaware, we have assumed that the laws of
the jurisdiction, organization or formation of such Guarantor with respect to
matters of authorization, execution and delivery do not differ in any material
respect from the laws of the State of Texas in those regards and have undertaken
no investigation of the laws of any jurisdiction or their effect, if any, on any
legal conclusion herein expressed other than, the laws of the State of Texas,
the State of New York and the Delaware General Corporation Law. We hereby
consent to the use of this opinion as an exhibit to the Registration Statement.


                                           Very truly yours,

                                           /s/ VINSON & ELKINS L.L.P.

                                           Vinson & Elkins L.L.P.
