Welcome to our article on how to fix drafty windows! If you live in an old house or apartment, you might have experienced the discomfort of drafty windows. Not only are they uncomfortable, but they can also increase your energy bills and harm the environment. In this article, we will provide you with practical steps to fix drafty windows, along with some tips and tricks that will ensure your windows are sealed and insulated properly.

Step-by-Step Guide to Fix Drafty Windows

Step 1: Identify the Drafts

The first step in fixing drafty windows is to identify where the drafts are coming from. You can do this by holding a candle or a lighter near the window, and if the flame flickers, it means there is a draft.

Step 2: Clean the Window Frames

Before you start sealing the windows, it’s essential to clean the window frames. Use a damp cloth to remove any dirt or debris from the frame. This will ensure that the sealant adheres properly to the frame.

Step 3: Apply Weather Stripping

Weather stripping is an inexpensive way to seal gaps around the window frame. It’s easy to apply and comes in different materials, such as felt, foam, or rubber. Measure the width of the gap and cut the weather stripping accordingly. Then, apply it along the gap, pressing it firmly against the frame.

Step 4: Apply Caulking

Caulk is a type of sealant that is used to fill gaps around the windows. It’s applied with a caulking gun and comes in different types, such as silicone, latex, or acrylic. Apply a thin and consistent line of caulk along the gap between the window frame and the wall or sill.

Step 5: Install Window Insulation Film

Window insulation film is a thin plastic sheet that is applied directly to the window glass. It creates an air pocket between the glass and the film, which acts as a barrier against drafts. Cut the film according to the window size and apply it using double-sided tape.

Step 6: Install Storm Windows

Storm windows are an additional layer of protection against drafts. They are installed on the exterior of the existing windows and come in different types, such as permanent or removable. They are especially useful for older homes with single-pane windows.

Step 7: Use Draft Stoppers

Draft stoppers are long cushions that are placed along the bottom of the window or door. They prevent cold air from entering the room and warm air from escaping. They come in different materials, such as foam, fabric, or leather.

Step 8: Install Exterior Louvers

Exterior louvers are slatted panels that cover the windows from the outside. They provide shade and ventilation during the summer and insulation during the winter. They are available in different materials, such as wood, aluminum, or vinyl.

Step 9: Replace Broken Seals

If your windows have broken seals, they can be a significant source of drafts. Replace them with new seals that fit snugly around the frame. You can find replacement seals at hardware or home improvement stores.

Step 10: Fill Cracks with Spray Foam

Spray foam insulation is a type of foam that expands rapidly when sprayed. It’s an effective way to fill gaps and cracks around the window frame. Ensure that you wear protective gear, such as gloves and a mask, when applying spray foam insulation.

Step 11: Install Window Shades or Blinds

Window shades or blinds can act as an additional barrier against drafts. They can be adjusted to let in natural light and air or keep them out. They come in different materials, such as fabric, bamboo, or aluminum.

Step 12: Schedule a Window Replacement

If all else fails, it might be time to replace your old and drafty windows with new and energy-efficient ones. Consult with a professional window company to find the best options for your home and budget.

Tips and Tricks for Fixing Drafty Windows

Tip 1: Invest in Energy-Efficient Windows

Energy-efficient windows can significantly reduce your energy bills and increase your home’s comfort. Look for windows with a good Energy Star rating and low-E glass.

Tip 2: Use a Window Insulation Kit

A window insulation kit contains all the materials you need to seal your windows, such as plastic film, double-sided tape, and a hairdryer. They are easy to use and are available at home improvement stores.

Tip 3: Consider Installing Window Inserts

Window inserts are a type of interior storm window that is installed inside the existing window frame. They are easy to install and can significantly reduce drafts and noise.

Tip 4: Use a Do-It-Yourself Window Sealant

There are many do-it-yourself window sealants available on the market, such as rope caulk or window glazing. They are inexpensive and easy to apply.

Tip 5: Check for Leaks with a Smoke Pencil

A smoke pencil is a device that releases a thin stream of smoke. It’s an effective way to detect leaks around the window frame, which can then be sealed.

Tip 6: Use Heavy Curtains

Heavy curtains can act as an additional layer of insulation against drafts. They can be closed during the winter and opened during the summer to let in natural light.

Tip 7: Add Insulation to Your Attic

Adding insulation to your attic can improve your home’s energy efficiency and reduce drafts around the windows. Consult with a professional insulation company to find the best options for your home.

Tip 8: Repair or Replace Your Window Screens

Window screens can develop holes or tears over time, which can let in drafts and bugs. Repair or replace them to ensure that they are in good condition.

Tip 9: Use Draft Guards for Doors

Draft guards are similar to draft stoppers but are designed for doors. They prevent cold air from entering the room through the gap under the door.

Tip 10: Consult with a Professional

If you’re not sure how to fix your drafty windows or if they require professional attention, consult with a reputable window company or contractor. They can provide you with expert advice and solutions that are tailored to your home’s needs.

In conclusion, fixing drafty windows requires some effort, but it’s essential for your comfort, energy bills, and the environment. By following these practical steps and tips, you can ensure that your windows are sealed and insulated properly, and that your home is cozy and energy-efficient.
