Why Replace Drafty Windows

Don’t underestimate how much heat or cool air is lost because of drafty windows. According to the Department of Energy, heat gain and loss through windows account for 25% to 30% of residential heating and cooling costs. To reduce your heating and cooling costs, window leaks should be addressed as soon as possible.

How can you tell if you have a drafty window? By keeping an eye and ear out for warning signs.

Why Replace Drafty Windows

Signs You Have Drafty Windows

Common warning signs are:

  • Rattling noises – Glazing putty is responsible for keeping your window’s glass panes in place. If it becomes brittle over time, your windows might produce rattling sounds whenever they’re hit by strong winds.
  • Gaps between the wall and the window frame – These gaps are usually caused by installation errors. However, gaps can also form if your window isn’t suited to your area’s climate. For instance, wooden window frames expand and contract as temperature rise and fall, potentially shifting window panes and forming gaps between the wall and window frame. That’s why it’s best to consult a professional contractor before choosing a window and door replacement.
  • Foggy window glass – Foggy windows are usually a sign there’s too much humidity inside your home. However, if the glass sealing around your window’s insulated glass unit is damaged, moisture can infiltrate the space between the two window panes, fogging up the insides of the glass panes.

Should You Repair or Replace Drafty Windows?

Most contractors would recommend installing new insulated replacement windows. Manufacturers fill insulated windows with argon or krypton, nontoxic gases that can prevent heat transfer. Window repairs can prevent these gases from leaking out but can’t restore a window’s overall energy efficiency.

"Absolutely wonderful experience working with renewal. They kept my wife and I up to date all throughout the process from the initial sales pitch to installation. They were courteous and professional throughout. The installation of 8 windows was completed in one day and the product is fantastic. Immediate difference felt inside the home and its much quieter now too. My wife and I are thrilled at our purchase. The windows are a bit pricey but worth every single penny. Wonderful product from a wonderful company. Will definitely be using them in the future to install the rest of the windows in our home."

"When I say, superior service I mean just that!! From start to finish I was pleased!! Step 1, Scheduled appointment at the Home show… easy. Step 2, phone call to confirm appointment the next week….easy. Step 3, in home consultation with Keith Billingsley…..Amazing!!!! Step 4, call and cancel all other Window companies and let them know you have chosen the Best company, Anderson Windows!!! My Windows took a couple of months to come which was not a problem. Oooohhh but when installing day came ( a week early) I was lost for words. The installation team was A1 with professionalism and cleanliness!! They didn’t leave a scrap of trash on my property. It was cleaned up both days. I had Ed Tutton and crew. I had a million questions and they answered every one of them and made me feel so assured with the process. A couple of my Windows had wood rotted. They took care of it and fixed it better than when the house was built!!! Two of my Windows came in broken, it was addressed and shown to us and reorder in the same day!! They will be installed later. The Windows are so beautiful I stood in my master bedroom Windows for almost 3 hours just looking out. I hate Window grates…. I have solid glass Windows now❤️❤️! I wish I would have ordered my new front doors from Anderson Windows. So if you are looking to get new Windows you must go with Anderson Windows!!!"
