Below are additional cost breakdowns. *Cost data based on sample pricing for window installation from multiple retailers and adjusted for local cost of living.

When To Replace Windows

Replacing your existing windows with new energy-efficient ones can significantly improve your home's comfort, insulation, noise reduction, value, and appearance. Signs it's time to invest in new windows include:

  • Outdated and inefficient window styles that take away from your home’s curb appeal.
  • High energy bills and discomfort from poor window insulation.
  • Windows that are hard to close, open, or lock properly due to age and wear.
  • Drafts and cold air leaking in from old, loose-fitting windows.
  • Condensation issues, fogging between window panes, or rotting window frames that let in moisture.

How To Choose a Window Company

Selecting a window installer with the right qualifications helps ensure a smooth installation. We explain the most important qualities to consider when selecting a qualified provider below.

Experience

Find well-established local installers with extensive experience. Providers that have been installing windows locally for many years are more likely to know the local climate and how to best meet your needs. Ask for references from recent customers to verify that a provider delivers quality work.

Certifications

Choose companies that have certifications from leading window brands, and that have Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Certification means they've received proper training in installation best practices. Make sure installers are staff rather than subcontractors, and confirm that any technicians working on your home are certified.

Reputation

Spend time reading through online reviews, checking the Better Business Bureau (BBB), and asking for local references. Review customer feedback to confirm that a company delivers consistent quality workmanship and great service. Avoid companies with complaints of shoddy work or unfinished jobs.

Process

The right company will take time to provide you with a comprehensive project plan, timeline, expectations, and reviews of all material and installation options. Beware of vague quotes or timelines that don't provide enough specifics upfront. Look for ongoing communication throughout the process to avoid surprises later on.

Warranties

Seek out window installers that provide installation guarantees on labor and materials. This demonstrates confidence in their work. Seek out companies with unlimited lifetime warranties that can pass to new homeowners.

Materials

Confirm that your window installer offers windows built for longevity as well as leading energy-efficient window bands that fall within your budget. Research choices with enhanced UV protection, good energy ratings, and design flexibility. Verify that the materials come with their own manufacturer warranties.

In Wentzville, the best time to install windows is when temperatures are mild, generally in the spring or fall. These conditions allow professionals to work without having to worry about the weather.

The best type of replacement windows for your Wentzville home depends on the year your home was built –the average house in Wentzville was built around 2000. For older homes, you may want to consider energy-efficient windows such as double-glazed windows, which are designed to keep your home cool in the summer and warm in the winter. Wood frames also have a classic look that's perfect for older homes. For newer homes, you might want to think about vinyl windows, which are durable, affordable and have a modern look.

Windows made from wood, fiberglass, or vinyl are known to last the longest, with some lasting up to 45 years. Vinyl windows are particularly durable and low-maintenance, making them an excellent choice if you want windows that will last a long time. Extra glazing can help reduce your heating and cooling bills over time.

The window installation process typically takes a day and a half for a standard home. But if you have many windows to install, it may take longer. Some contractors can complete the project in a single day, depending on the size of the job.

After window installation, it's important to check for any air leaks and make sure the windows are properly sealed. You should also wash the windows regularly to prevent debris from accumulating and leading to damage. Additionally, if you live in an area with a lot of rainfall, you should check the window sills and frames once a year to make sure that the seals are not deteriorating or cracking.
