What affects the cost of replacement windows?


Window material

The type of material you choose for your windows and doors impact your project’s cost. At Infinity, we use Ultrex® fiberglass for our windows and doors. Why fiberglass? Because it outperforms and outlasts other options. You may save some money on your initial project costs by choosing a less expensive vinyl option, but vinyl windows are more prone to expansion and contraction that can lead to problems down the road.

Wood windows are another popular replacement option. They tend to require more maintenance and care, which adds to the lifetime cost of your project. If you like the look of wood, Infinity’s EverWood® interior offers all the classic appeal of wood — without the maintenance.

Window features + options

Each window and door can be customized to your specific taste. You may notice your project cost increase as you add more decorative options to your project — just like adding more options to a brand-new car.

Window + door installation

We’ve all started DIY projects that end up taking longer and costing more money than expected. The same goes for DIY window and door replacement. The cost of professional window installation is based on the number of windows being replaced plus any special considerations — such as prepping for a new window opening or extensive finish work if your current windows and trim are in bad shape.


Budgeting for window and door replacement

Gathering quotes for window replacement can lead to initial sticker shock. Don’t worry if your project sounds like it might cost more than anticipated. Infinity experts will work with your budget.

You could approach your project in phases. Start with the front of the house or the kids’ bedrooms — whatever needs replacement first. That way you can save in between phases while still improving your home’s comfort.

Many homeowners finance their home improvement projects to spread out the cost over time. Be sure to ask during your consultation about any special financing offers that are running. Financing can help make your project fit your budget — or allow you to increase your buying power to replace all your windows and doors at once by dividing the project into affordable monthly payments.


Return on investment

Like any home improvement project, new windows and doors can add value to your home — an average 68-72% return on investment which ranks higher than most interior renovations. Fiberglass windows also have a longer useful life expectancy than vinyl.
