Frequently Asked Questions
How much do replacement windows cost?
The cost of replacement windows varies depending on the window size, style, material, glass package, installation requirements, and number of windows being replaced. An in-home consultation can help determine the right options and provide accurate project pricing.
Should I replace all my windows at once?
Not necessarily. Some homeowners replace all their windows at once, while others complete the project in phases. The right approach depends on the condition of your existing windows, your priorities, and your project budget.
What is the difference between replacement and new construction windows?
Replacement windows are typically installed within an existing window opening, while new construction windows are commonly used for additions, new homes, or projects where the existing window and surrounding materials are being removed.
What window material is best?
The best material depends on your home’s architecture, desired appearance, maintenance preferences, performance requirements, and budget. Different window collections offer options including wood, fiberglass, aluminum, and other materials.
How long does window installation take?
Installation time depends on the number and type of windows or doors being installed, existing conditions, and the complexity of the project. Your window and door professional can provide a more specific installation timeline after evaluating your home.
What are the most energy-efficient windows?
Energy-efficient windows can include features such as insulated glass, Low-E coatings, multiple panes, quality frame materials, and appropriate glazing packages. The right combination depends on your home, window orientation, climate, and performance goals.
Do you offer Marvin windows?
Yes. Marvin is one of the premium window and door manufacturers available for projects. Options include replacement and new construction windows as well as architectural door systems in a variety of styles, materials, and finishes.
Can windows and exterior doors be replaced together?
Yes. Windows and exterior doors can often be addressed as part of the same home improvement project. Coordinating them together can also help create a more cohesive exterior design and simplify product selection and project planning.
