Welcome to The Main Company
Relationships we've built
  • "I have been very pleased with TMC's attention to detail, their anticipation of future issues before they became problems and their sense of design. If you are considering them for making your investment a reality, I would suggest that you look no further."
  • "Charlie and his crew were respectful of our requests and my wife and I never felt our wishes or our home were being treated as just another job. They were doing their work in the manner they would have done it just as if it was their own home."
  • "Charlie Main has been our friend since 1991. We were impressed by his enthusiasm and experience as a “high end” home builder. We worked with him to build our 5000 sq ft home, which he accomplished in eight months with no hitches."
  • "This project had been sitting on the table for many years. The initial costs of the project were staggering for a congregation of our size, but with the help of The Main Company we were able to get the job done. The teamwork and spirit that they brought to our church will forever be remembered."
  • "I feel that Mr. Main has excellent knowledge of the construction industry, is an honest man, and is willing to work as a team player to deliver the best product at the best price to the owner. I would recommend him for future projects without hesitation."
  • "I have just completed working with Charlie Main on a project that presented some difficulties as it bordered on property lines with other existing businesses. Charlie did a good job coordinating the construction challenges as the project unfolded. The quality of the work was excellent and I would welcome a phone call from anyone to give a personal recommendation for Charlie Main."
  • "I have found Charlie to be an extremely valuable and experienced project manager. His management and technical skills, along with his foresight and thoroughness, kept projects on schedule, within their budget and of high quality."
  • "After over 20 years of professional experience dealing with all trades in all parts of the world, I continue to learn from my experience with Charlie. I am especially impressed by his continued sincere concern for his clients. I consider myself and the entire staff at Portney Construction very fortunate to be associated with The Main Company."
