Step 1: Weatherizing your home starts with checking for cracks

Homes, whether new or old, often have cracks and openings around doors and windows. These gaps are a major source of heat loss and can account for up to one-third of your home’s overall heating cost. That’s why you should apply caulk and weather stripping around your doors and windows.

 

After all, heating and cooling costs account for nearly half of home utility expenses, and poor sealing is a contributing factor to those costs. Other factors include insulation, the number of stories in a house, the number of air conditioning units, windows and more.

 

When you consider that even a tiny 1/8-inch gap around a typical entryway door is the equivalent of drilling a 5 ½-inch-diameter hole through an outside wall, closing that gap is well worth the effort.

 

When you’re checking for leaks, some are pretty easy to detect, like the crack of light beneath the front door on a sunny day, or the rush of cool air coming from a window on a blustery day. But there may be far less obvious leaks that may take some creativity to discover.

 

Here’s an easy way to detect leaks around doors and windows in your home:

 

On a windy day, turn off your A/C unit and close all the doors and windows. Turn on any bath fans and stove vents in your home. Then light a stick of incense and pass it along the edges of your doors and windows. Wherever the smoke is sucked out or blown into the room, there’s a leak.

Step 2: How to caulk

Caulking to seal gaps around doors and windows is an easy, energy-saving DIY project any homeowner can take on to lower their utility bill.

 

There are several basic types of caulking compounds available including latex, silicone, polyurethane, and hybrid formulas, making it possible to tackle a variety of sealing jobs.

 

Latex caulk is a cost-efficient option that is easy to work with and
  can be painted if needed. Latex is versatile and can be used on 
  a variety of surfaces, including doors and  windows, and cleans
  up nicely with soap and water.


           
Silicone caulk offers good flexibility, durability and adhesion,
  providing an excellent seal against the outside elements.
  Silicone caulk is perfect for use around doors and windows
  in areas exposed to moisture or direct sunlight. Silicone
  products cannot be painted as they are engineered to 
  not have anything stick to the surface.
           
 

 • Polyurethane caulk provides outstanding adhesion and is
   also very durable, but can be more difficult to work with.
   Most polyurethane products are engineered for exterior
   use and can also be applied to a damp or wet surface if
   needed.          
     

 

• Hybrid products offer you the best of each technology,
  without the drawbacks. These products can be applied
  to a damp surface, painted in a relatively short period of
  time, and applied to any surface. Hybrid products provide a
  durable, long-lasting seal regardless of where they are
  used.

 

Most caulking products come in a 10 ounce cartridge and are applied with a caulking gun. You can also find latex and silicone products in smaller squeeze tube sizes if you don’t want to use a caulking gun or if a smaller amount of product is needed for your job.

 

Before applying a new layer of caulk, you’ll need to remove any older caulking with a utility knife or scraper, carefully clean away any dirt and debris from the area and allow the surface to dry.

 

When you’re ready to start caulking, first load the caulk gun by pulling back the plunger and placing the tube of caulk into the chamber, bottom end first.  Squeeze the trigger until it makes contact with the tube.

 

Cut the tip to your desired bead size at an angle, using the pin on the caulk gun to puncture the seal if needed. Apply pressure by squeezing the gun until the product makes its way to the end of the nozzle.

 

Holding the gun at a 45 degree angle to ensure the gap is covered, squeeze the trigger as you push the gun away from your body to ensure that you are using enough caulk to fill your gap.

 

When finished, release the trigger at the end of the seam, pushing the tip of the nozzle into the corner to cut off the strip of caulk and twist slightly as you lift the nozzle. Make sure to cap the top of the nozzle as most caulks can be stored and re-used at a future time.

 

There are a variety of methods that can be used to smooth the caulk, ranging from running your finger along the bead to using a professional caulk tool for optimal results. The type of caulk you use may impact the method used to smooth the product out.

 

Caulking doors and windows is a really quick and simple process, leaving your home warmer, more comfortable and more energy-efficient when you finish.

 

Step 3: Weather stripping doors and windows

 

Weather stripping doors and windows is another cost-effective way to reduce energy waste. Weather stripping products come in many different forms, and can be made up of a combination of materials such as wood, rubber, vinyl, metal and foam.

 

To determine the type of weather stripping that will be the most effective in the area you are trying to seal, you’ll want to consider factors like the amount of friction it will have to withstand, exposure to weather and any cosmetic concerns you may have with it being seen.

 

Even the most inexperienced DIYer can apply weather stripping.

 

Adhesive-backed foam tape is sold in rolls in varying widths and thicknesses with a sticky back. Just cut it to the desired length and apply it to the top and bottom of window sashes or inside door frames

 

V-strip, also known as tension seal, is a durable plastic or metal strip folded into a V shape that springs open to bridge gaps. You can cut it to length and either peel and stick it or nail it along the sides of double-hung or sliding windows.

 

Felt is another great choice for weather stripping around a door or window sash, or in the door jamb. Felt is easily nailed or stapled in place, and it compresses to allow smooth movement of doors and windows.

 

For the base of doors and windows, the top or bottom of a window sash, or between a door and its jamb, tubular rubber is an effective air barrier. Made up of a narrow sponge rubber or vinyl tubing sometimes attached to a wood or metal mounting strip, tubular rubber comes peel and stick or can be fastened with screws through slot holes.

 

And lastly, any well-sealed door requires door sweeps. Door sweeps are flat or U-shaped pieces of plastic, aluminum or stainless steel fitted with a strip of nylon, plastic, vinyl or a sponge brush to fill the space between the door and the threshold. Cut it to your door's width and install it along the bottom of the interior side of the door with screws. Door sweeps keep cool air and heat in and insects and other unwelcomed visitors out.

 

All together, you can save up to $200 a year in heating and cooling costs – or about 10 percent on your energy bill -- by sealing and insulating your home with ENERGY STAR-rated products.

 

Other areas you may want to weatherize

Doors and windows are the primary place you’ll want to check for air leaks, but there are other areas that are worth checking, too:

 

Around attic stairs: If you have pull-down stairs that lead up to your attic, the back cover that holds the stairs in place once folded tends to have a gap between itself and the ceiling. Weather stripping around the edges of the back cover will keep the untreated attic air from entering the temperature-controlled areas of your home.

 

Fireplaces: If your home has an active fireplace, consider using a glass door surround. With one-piece construction, it’s designed as a surface mount that sits outside the fireplace against a flat surface. Using a fireplace glass door reduces heating or cooling loss by as much as 90 percent.

 

Pipes: Using fiberglass or polyethylene pipe insulation covers protects your pipes against freezing. There are a variety of sizes, so there is insulation for just about every size pipe, including elbows and tee connectors. Also, pipes are often positioned inside walls, floors and ceilings via holes. Caulking around these holes closes any gaps where untreated air can enter your home.

 

Outdoor spigot/faucets: Using slip-on outdoor spigot/faucet covers protect your exposed pipes and valves against freezing and drafts from entering through faucet cutouts.


Electrical outlets and switches: Using a foam insulation kit for electrical outlets and wall plates will reduce drafts that can enter your home for walls that are exposed to exterior elements on one side.

 

Your attic and the floor above your basement: Make sure your attic and the floor above your basement has enough insulation to keep your home properly insulated to ensure an energy-efficient home. Depending on where you live, match up the amount of insulation in your attic and floor to the R-values assigned to your region.

 

If your number comes up short, add the appropriate amount to ensure proper coverage.
