Your Airtight Cincinnati Home: A Simple Guide to Weatherstripping

Schedule Now

With winter upon us, it’s time to check windows and doors for air leaks and add weatherstripping where it’s needed. Weatherstripping will save you on heating costs by keeping cold air out and warm air in; it will also improve home comfort by eliminating pesky drafts.


There are several types of weatherstripping that work well on doors. Metals such as stainless steel, copper and aluminum can be attached at the bottom and along the door’s side. The aluminum or stainless strip should be attached on the inside if the door opens inward and on the outside for doors that swing out. This type of weatherstripping should last for several years.

A peel and stick V-strip works as a tension seal along the sides and tops of doors. Felt strips can also be used in the door jams but that strip will probably last only a year or two. Foam tape that works on the inside of the door jam also has a short lifespan.

A vinyl or rubber door sweep fits below a metal strip over the threshold of a door. It’s applied on the interior side of a door and it can brush the carpet or hard flooring while forming a seal. The sweep can occasionally be applied to the side of a door.


Some of the same materials can be used on window sashes to seal them during cold weather. Windows will receive less use than doors during the winter months and the foam or felt stripping may last longer.

A tubular strip of silicone, vinyl or rubber can be placed at the top or bottom of a window sash. V-strips can also be used for windows.

Mix weatherstripping materials based on your needs for windows and doors.

"Ernie & Mike did a superb job on my new furnace and A/C installation. Despite having more than a day’s work to do, they came in and stayed until the job was done. They were organized, efficient, and protected the rest of the house well. Got both furnace and A/C installed the same day. Ernie was courteous, informative, and clearly knew his job better than anyone I’ve encountered before. The units look so good guests now get The Tour of our new system. Apollo is clearly not a fly-by-night company. I would recommend them to anyone in need of a new furnace and/or A/C."

"I called Apollo because of a water leak I thought I had in our upstairs shower going into the kitchen. Robbie came and assured me everything was fine & looked at all the other plumbing. He ended up changing a few pipes for our washer & clearing a drain. He was very nice & knowledgeable with all my questions. I ended up signing up for the care plan & was very happy with my service."

"The team at Apollo exceeded my expectations. As a business owner, my attention to the details and commitment to providing excellent service is high. From the sales rep. to the installation team, everyone’s performance was outstanding. For example, the installation team went to great lengths to protect our floors, placing floor runners and across the wood floors and up the stairs. They even were spot washing walls upon their departure. I highly recommend this company."

"We scheduled an estimate AND a tune-up. We knew something was wrong with our furnace, but hoped we could make it through the rest of the season. Upon telling Bill what our furnace was doing, he warned us immediately what the possible outcome was going to be; a cracked heat exchanger. He watched the flames roll backward, tested carbon monoxide levels, which were so high they meter’s last reading was 5,600 before saying “high”. He immediately shut it down, tagged it, and explained that with levels that high and children in our home he wanted off right away. He continued his inspection and showed us via a camera that not only was it cracked in multiple places, but had holes all over it. He gave us a few options for repairing it; his knowledge as well as genuine concern was beneficial and refreshing. Luckily we also scheduled an estimator, Micah, to come too and we were able to get costs between repairing and replacing (with several options). We decided to replace with a much higher efficiency furnace and one sized properly to our home. Hands down, not only did they both provide us great service and knowledge, but without sounding dramatic, they may have saved our lives. This was our first time calling Apollo, but it won’t be our last."

"Apollo is an excellent company. I always receive great service. Alex A. was professional and friendly. He kept me informed during the process of checking my furnace and heat pump to make sure they were working properly. The company makes sure you are notified who is coming and when they are on the way. All my interactions with the company have been wonderful."
