How Much Does Window Installation Cost In Decatur?

Window installation and replacement costs depend on several factors, including how difficult your windows are to access or install, the number and size of the windows, and the materials you choose. On average, Decatur homeowners spend around $280 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

Replacing your old windows with new energy-efficient ones can substantially enhance your home's noise reduction, appearance, value, insulation, and comfort. Clear indicators it's time to invest in new windows include:

  • Inefficient and outdated window styles that take away from your home’s curb appeal.
  • Cold air and drafts leaking in from old, loose-fitting windows.
  • Windows that are hard to close, open, and lock properly due to wear and age.
  • A chilly house and high energy bills from poor window insulation.
  • Fogging between window panes, condensation issues, or rotting window frames that allow moisture intrusion into the home.

How To Choose a Window Company

For a successful window replacement, you need to find an installation contractor with proven expertise. Below, we go over the most important considerations when selecting a 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 Decatur's climate and your requirements. Request references from recent clients to confirm the quality of a company's work.

Certifications

Choose companies that have certifications from major window brands, and that have Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Being certified indicates that 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 reviewing online feedback, checking the Better Business Bureau (BBB), and asking for local references. Review customer feedback to verify that the company consistently does quality work and provides good service. Avoid companies with complaints of shoddy work or unfinished jobs.

Process

A reputable provider will give you a detailed project plan, detailed timeline, clear expectations, and an overview of all material and installation options. Avoid providers that offer vague quotes or timelines. Insist on continual contact throughout, so you aren't caught off guard later on.

Warranties

Research window installers that back their installations with guarantees, and that provide warranties on products and labor. This indicates confidence in their work. Also seek out unlimited lifetime warranties that can be transferred 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 enhanced UV protection, design flexibility, and good energy ratings. Check that the window materials also have manufacturer warranties.

Frequently Asked Questions About Window in Decatur, GA

The ideal time to install windows in Decatur is when temperatures are moderate, generally during spring, winter or fall. These conditions allow professionals to do their work without having to worry about the weather.

The best type of replacement windows for your Decatur home depends on when your home was built –the average house in Decatur was built around 1976. For older homes, you might want to consider energy-efficient windows such as double-pane windows, which are designed to keep your home cool in the summer and warm in the winter. Wood frames also have a timeless look that's great for older homes. For more modern homes, you can think about vinyl windows, which are durable, affordable and have a modern look.

The types of window that usually last longest are ones constructed from vinyl or wood, with double glaze for extra insulation. Vinyl windows are famous for their long-lasting nature and require minimal maintenance, while wood windows provide a more timeless look. Tripling up on the glazing will reduce energy costs in the long run. This is especially helpful during Decatur's hot summers.

The window installation process typically involves ordering and measuring the windows, preparing the area for installation, taking out the old window, installing the new one, and sealing the frame. Depending on the kind of window being installed, additional steps might be needed.

In some cases, you can replace your own windows, but it's better to hire a professional. It's important to consider the local temperature when replacing windows, as it will affect the process. For example, the temperatures in Decatur can reach an average high of 70, so you should consider energy-efficient windows that can protect from the heat. It's also important to get the measurements right and understand the instructions for installation. Hiring a professional for your window replacement project will guarantee that everything is installed correctly.

Yes, most 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 offer special financing plans with agreements and conditions that vary depending on the job.

Window replacement companies in Decatur typically offer many services, such as installation, fixing windows, window maintenance, cleaning, tinting, and weatherproofing.
