How Much Does Window Installation Cost In Kennesaw?

The cost of window installation or replacement will be influenced by 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, homeowners in Kennesaw spend roughly $270 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 comfort, noise reduction, insulation, appearance, and value. Signs it's time to invest in new windows include:

  • Drafts and cold air coming in through old, loose-fitting windows.
  • Windows that are hard to open, close, and lock properly due to age and wear.
  • A chilly house and high energy bills from poor insulation.
  • Outdated and inefficient window styles that take away from your home’s curb appeal.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 installation company helps ensure good results and a great experience. Below, we outline the main considerations for selecting a qualified window installer.

Experience

Make sure you select a seasoned local installer with a proven track record of successfully installing and replacing windows. Providers that have been operating locally for many years are more likely to have a deep knowledge of the local climate and local homeowners' needs. Get references from recent clients to confirm a company provides quality installations.

Certifications

Choose companies that have certifications from top 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 the technicians doing your job are certified.

Reputation

Spend time going through online reviews, checking the Better Business Bureau, and requesting local references. Review customer feedback to verify that the company regularly provides good workmanship and service. Steer clear of companies with complaints of shoddy work.

Process

A good provider will give you a comprehensive project plan, reasonable timeline, clear expectations, and an overview of all material and installation options. Avoid providers that offer vague quotes or timelines. Ask for regular contact throughout the process, so you aren't caught off guard once the work begins.

Warranties

Seek out window installers that assure quality installations and provide warranties on labor and materials. This demonstrates confidence in their work. Select companies with unlimited lifetime warranties that can transfer to new homeowners.

Materials

Ensure that a company works with durable, energy-efficient window brands that fit your budget. Look for good energy ratings, design flexibility, and enhanced UV protection. Confirm the window materials come with their own manufacturer warranties as well.

Frequently Asked Questions About Window in Kennesaw, GA

The ideal time to install windows in Kennesaw is when temperatures are moderate, generally during spring, winter or fall. This enables professionals to work with less worry about the weather.

The best type of replacement window for your Kennesaw home will vary based on the age of your home, as well as your personal style and budget. You'll want to consider the style of your home — such as if it's more modern — so your new windows match. Wooden windows can provide a traditional look and feel, while vinyl windows tend to be popular in newer homes. Fiberglass-framed windows are also a popular choice, as they can be energy efficient and long-lasting.

You can save money on your window installation by going with a less expensive option like single-hung windows with vinyl frames. These have lower prices compared to other kinds of windows like double-hung, fiberglass, or wood windows.

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 at least once a year to stop debris from building up and causing damage. Additionally, if you live in an area with abundant rainfall, you should inspect the window sills and frames regularly to ensure that the seals are not deteriorating or cracking.

Hiring a professional window installer helps make sure the job is done correctly. Professional installers will measure your windows properly to get a perfect fit and use the right materials and techniques to ensure your windows are properly sealed and secure. Additionally, professional installers have access to higher quality materials and more knowledge than the average homeowner, so you can expect your windows to be put in correctly and last for years to come.
