What drives the price of window installation in San Jose
Two window installation companies can quote the same job and land hundreds of dollars apart, because the price is set less by the company than by the work itself. For window installation, the factors that move the number most are:
- The number and size of windows.
- Replacement versus new construction.
- Frame material and energy rating.
- Trim and finish work.
Before you compare quotes, write down your version of each of these. When every window installation companies prices the identical scope, the cheapest bid is finally a real deal rather than a different, smaller job in disguise.
