Home improvement contractors are generally companies that manage and construct improvements to existing residences—whether kitchens, bathrooms, bedrooms, or complete remodels.

A contract for home improvement includes a description of the scope of the work to be performed; the materials to be used; the general contractor’s obligations to hire and manage subcontractors to construct the various components of the building; the payment terms for the construction of the building and the management of the construction; the time for completion of the work; insurance requirements; and the filing and removal of mechanic’s and materialmen’s liens (also known as construction liens or contractor liens) for labor and materials provided to improve the real estate.

In Montana (MT), home improvement contractors are regulated to ensure consumer protection and fair business practices. Contracts for home improvement must be clear and comprehensive, including a detailed description of the work scope, materials, contractor's obligations, payment terms, completion timeline, insurance requirements, and provisions regarding mechanic's and materialmen's liens. Montana law requires that contracts for home improvement projects over a certain amount must be in writing. Additionally, contractors must be aware of the Montana Construction Lien Law, which governs the filing and enforcement of construction liens. These liens ensure that contractors and subcontractors can secure payment for labor and materials provided to improve real property. Failure to adhere to these regulations can result in legal disputes and financial penalties. It is advisable for both contractors and homeowners to consult with an attorney to ensure that contracts are legally sound and that they understand their rights and obligations under Montana law.
