How Much Does Window Installation Cost In Dunwoody?

The cost of window installation or replacement is influenced by a number of factors, including the materials you choose, how difficult your windows are to access or install, and the number and size of the windows. On average, homeowners in Dunwoody should expect to spend about $290 per window*. 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

Adding new energy-efficient windows can greatly increase your home's value, appearance, noise reduction, insulation, and comfort. Signs that it's time to invest in new windows include the following:

  • Drafts and cold air coming in from old, loose-fitting windows.
  • Discomfort and high energy bills from poor window insulation.
  • Windows that are hard to close, open, or lock properly due to wear and age.
  • Outdated and inefficient window styles that reduce your home’s curb appeal.
  • Condensation issues, fogging between window panes, or rotting window frames allowing moisture intrusion into the home.

How To Choose a Window Company

Hiring an experienced window installer contributes to good results and a great experience. Below, we outline the main factors to consider when selecting a qualified window installer.

Experience

Look for well-established local companies with a long track record of experience successfully installing all kinds of windows. These providers are more likely to understand Dunwoody's climate and your requirements. Ask for references from recent clients to verify quality and experience.

Certifications

Look for installers that are backed by major window manufacturers and accredited by top industry associations, including the Fenestration and Glazing Industry Alliance, formerly known as the AAMA. Appropriate accreditation indicates that a provider has received suitable training in installation best practices. Ensure installers are employees rather than subcontractors. Verify that the technicians assigned to your job have the right certifications.

Reputation

Spend time looking through online reviews, checking the Better Business Bureau, and asking for local references. Review customer feedback to confirm that the company consistently delivers good workmanship and service. Steer clear of companies with complaints of shoddy or unfinished work.

Process

A quality provider will give you a comprehensive project plan, detailed timeline, clear expectations, and an overview of all material and installation options. Avoid providers that offer unclear quotes or timelines. Ask for ongoing contact throughout the process, so you aren't caught off guard when installation starts.

Warranties

Seek out window installers that assure quality installations and offer warranties on materials and labor. This is a sign of expert workmanship. Opt for companies with unlimited lifetime warranties that can transfer to new homeowners.

Materials

Make sure the window company offers durable, long-lasting window options and top energy-saving window brands within your budget. Look for good energy ratings, design flexibility, and enhanced UV protection. Check that the window materials also include manufacturer warranties.

Frequently Asked Questions About Window in Dunwoody, GA

In Dunwoody, the ideal time to install windows is during the winter when the temperature is not as high, so the windows can fit and adjust properly. A professional local window installer in Dunwoody will be able to tell you when the best time is to install windows on your home.

The best type of replacement windows for your Dunwoody home depends on the year your home was built –the average house in Dunwoody was built around 1986. For older homes, you may want to consider energy-efficient windows such as double-pane windows, which are made to keep your home cool in the summer and warm in the winter. Wood frames also have a timeless look that's perfect for older homes. For newer homes, you may want to think about vinyl windows, which are durable, affordable and have a modern look.

Windows made from wood, vinyl, or fiberglass tend to last the longest, with some lasting up to 45 years. Vinyl windows are especially durable and low-maintenance, making them a good choice if you want windows that will last a long time. Extra glazing can help reduce your cooling and heating bills over time. This is especially helpful during Dunwoody's hot summers.

The process for window installation typically includes taking measurements, removing the existing windows, installing the new windows, inspecting for proper sealing, and applying caulk around the edges of the frames. Additional steps may be necessary depending on the kind of window being installed.

After window installation, it's important to check for any air leaks and make sure the windows are properly sealed. You should also clean the windows at least once a year to prevent debris from building up and causing damage. Additionally, if you live in an area with abundant rainfall, you should check the window sills and frames regularly to ensure that the seals are not wearing away or cracking.

Yes, many window companies provide financing options. Some installers provide low-interest or no-interest loans, although you may not qualify if your income is on the higher end, while other companies provide unique financing plans with terms and conditions that vary depending on the project.

Window companies in Dunwoody usually offer a range of services, including measuring and installing new windows, repairing existing windows, replacing window glass, and installing window treatments. They may also offer extra services such as weatherproofing or cleaning.
