Winter Energy Efficiency: How Windows and Air Leaks

Share this post

When you think of cold air invading your premises, you wonder where it comes from in the first place. Sometimes, the air comes through places where you least expect them—such as through electrical outlets that contain gaps. And often, air comes through windows that are not properly insulated to endure a rough winter season. Aside from replacing windows during a drafty season, there are easy ways both residents and managers can make amends for less than stellar weather.

There’s the often obvious solution of putting plastic over windows—which reduces the amount of heat that escapes through the cold glass of windows. It is cheap and effective, requiring only plastic sheets and some strong tape as adhesive. Caulking comes in handy during the winter, too. Some buildings have various cracks that open up in the wintertime and get smaller during the summer. These are more prevalent in older structures and occur everywhere, from door frames to roofs to around windows. Instead of letting warm air escape into the abyss, caulking can help seal in the air.

The same methodology works just for windows. Rubber sealant, which can be purchased at any hardware store, can be cut to fit your windows’ dimensions and keep out drafts. It’s cheap, effective and not an eye sore—except maybe until the sealant is ripped off in the spring. Shades and curtains provide different patterns for aesthetic purposes, and they also allow residents to choose how much light they want to shine in the first place. It’s natural heat when the windows are open, and shades can be adjusted to allow only a certain amount of light to come inside.

The merchants were very knowledgeable, explaining everything from the construction of the windows themselves to the installation process. The workman was knowledgeable, efficient and meticulous. He was polite and easy to work with. The installation was seamless from start to finish. One of the supervisores came out to check his work. I will definitely hire them again and refer them to others.
Response from the owner:Thanks for sharing Anne! We’re glad the whole process was smooth & we strive to deliver the utmost care & attention to all our work so everyone can be just as satisfied as you. Thanks again for the trust and for recommending us. We’d be happy to help anytime.

Great company, I highly recommend! Complete roof tear off (2 layers) and replacement on a 2800sf colonial including removal of old solar panels and skylight replacement as well as gutter replacement completed in under 2 days. Extremely professional and knowledgeable crew and management. They are efficient, neat, courteous, and meticulous. The finished product is amazing, price and financing options are great, and the Warranty is the best in the business.
Response from the owner:Hi, Dave. We are thrilled to learn that you had a positive experience with us! Thank you so much for the kind review.

Lemus approach to our GLV Roofing Project has been spot on from daily management to workers endurance in exceptional heat, especially on the roofs when the heat registered at 130 degrees. I can verify that my Copperfield neighbors came to the aid of Ken’s roofers and ground help. We refilled Gatorade, lemonade, watermelon, cookies, zucchini loaf and even had a chance to treat all of the ground crew to warm sandwiches of BBQ and salad. The crew is respectful and considerate and they clean up every evening. This is just my message but I am sure so many other folks feel so much the same way.
Response from the owner:Hi Bernie, thank you so much for your kind words. We’re thrilled to hear that you’re satisfied with our work and management on the GLV Roofing Project. It’s great to know the crew’s hard work and endurance didn’t go unnoticed, especially in those extreme heat conditions. We appreciate the community support from Copperfield neighbors—it truly makes a difference for our team. Thanks again for your thoughtful feedback!

We had a disastrous situation by a previous contractor (I'd love to name them but won't) on our commercial roof. We were expecting a full replacement would be needed. Victor met with us on site. We walked the entire roof and he pointed out the problem spots and explained in detail, the work that would be needed to remedy our issues. His estimate was very fair and he was up front about some potential additional work that might be needed that could not be determined at the time of the survey. Those costs came in at a minimum when the work was done. Lemus's professionalism & craftsmanship was incredible from the start of the process to the end. Our issues are completely resolved and we are no longer worried every time it rains!
Response from the owner:Hi Fran, we’re so happy to hear this feedback! From the start, our goal was to provide you with a clear, honest assessment of your commercial roof and create a repair plan that would last. Victor’s walkthrough, pointing out problem spots and explaining the process, is exactly how we strive to keep homeowners and property owners informed every step of the way. We’re proud that our roofing team delivered quality craftsmanship that not only fixed the issues but also brought back your peace of mind. You’ve been a pleasure to work with, and we’re truly grateful for your support and trust in Lemus Construction.

Very friendly and helpful customer service. Roofing repair supervisor explained the process and kept me informed with drone pictures. Lemus was on time and completed project earlier than expected. They also left my property in pristine condition. The only indicator they were there was a beautiful new roof and a small Lemus sign. I plan to use Lemus again and recommend them to friends and family. :)
Response from the owner:Hi Rosetta, thank you for taking the time to share your experience with us. We appreciate your business and value your feedback. If there is anything else we can do for you, please let us know!
