The "Deferred Maintenance" eBook by Church Growth Services warns that postponing necessary facility repairs and updates can lead to escalating costs and jeopardize a church's financial health and sustainability. Neglected maintenance—ranging from critical systems like HVAC to aesthetic elements like outdated carpeting—can diminish a church's appeal and effectiveness in ministry. The eBook emphasizes that every dollar deferred today could result in four to thirty times the expense later, urging churches to adopt proactive maintenance strategies, establish reserve funds, and incorporate lifecycle planning into their budgets to prevent future crises.
