About Us

Sheridan Construct is committed to excellence 365 days a year.

How is Sheridan Construction Corporation different from other Maine commercial contractors? Our dedication to quality.

Sheridan Construction Corporation’s people are committed to excellence – 24/7, 365 days of the year.

Our determination to protect our clients’ interests has been the key to our success and is the reason why 70% of our clients have hired Sheridan Construction Corporation for more than one project.

Another statistic that shows how Sheridan Construction Corporation is different from our competitors: Our company’s average employment length exceeds 10 years, and several employees have been with the company for over 40 years. This low employee turnover allows us to maintain extraordinary control of the quality and scheduling of our projects.

The upshot? Lots of handshakes and smiles. From drafting table to ribbon cutting, Sheridan Construction Corporation clients enjoy a better building experience.

Since 1947 …

  • Sheridan Construction Corporation has designed and constructed 3000+ value-engineered buildings across Maine and the Northeast, including landmark projects in all economic sectors—industrial, commercial, municipal, institutional, and retail.
  • Sheridan Construction Corporation is the only Maine builder to receive the premier Butler Builder® designation.
  • Sheridan Construction Corporation was the first Maine construction company to require hard hats and safety nets on every job site. We developed innovative safety products and procedures that are still highlighted in OSHA training videos.
  • Sheridan Construction Corporation’s in-house concrete, steel, insulation and carpentry craftsmen work on site and in our 20,000 sq. ft. fabrication facility, giving us more control over scheduling and quality, and helping us deliver projects on budget and on time.


I would like to take this opportunity to compliment your employees for the outstanding job that was done at the new public works facility that was built by Sheridan Construction Corporation. Mr. Nelson, if these men were my employees, I would be very proud and honored to have these men working for me.
