What affects the price
Remodeling your entire home involves many variables that shift your final bill. The biggest factor is the scope of work; moving plumbing or knocking down load-bearing walls costs significantly more than simple cosmetic updates like new flooring or paint. Your choice of materials also creates a wide gap, as custom cabinetry and high-end stone counters carry a premium compared to stock options. Additionally, the size of your square footage and the current condition of your home’s electrical and HVAC systems play a major role in labor hours. Exact pricing confirmed free on the call.
