Our annual ranking of top construction firms highlights the top companies in Windsor on their project volume over the past year, with a focus on relevance. This compilation is derived from permit and contractor information sourced from city, county, and state building departments through our partners at BuildZoom. For further information regarding data accuracy, please consult the note at the end of this article.
Construction data is useful for many people involved in the building industry. Companies that supply materials and services to general contractors can use construction market data to reach the right customers at the right time. By keeping track of important events, like the start of big construction projects and related permits, they can offer their products and services when contractors are most likely to need them. They can also study how contractors grow their businesses and focus on those who are expanding. Subcontractors can use construction data to find and connect with general contractors for new jobs. At the same time, real estate developers, property owners, and others looking to hire contractors can use detailed information to check the skills and reliability of contractors and subcontractors before starting a project.
