Six Winter Specific Insulation Problems

In the winter months, the internal temperature of your home is dramatically different from that outdoors.  For this reason, home insulation deficiencies can be easier to spot.  If you’re experiencing any of the below scenarios, it’s a silent signal from your home that more insulation, ventilation, and attic air sealing are likely needed.

Chilly Rooms & Floors

If exterior air can make its way into your home, it’s not long before floors become unbearably cold and rooms are much cooler than normal.  The rooms that are the most susceptible to lower winter temperatures are most often above the garage or right below the attic.

Go Behind the Scenes on a Recent Insulation and Ventilation Project:

Pricey Heating Bills

If your home energy bills skyrocket in the winter months, it’s a signal that your furnace is running more than it should.  Not only does this cost you more money, but it also puts unnecessary strain on your furnace, making it more likely that it will wear out faster than it should.

Ice Dams

An ice dam is a layer of ice that forms on a roof edge.  Rather than permitting the melting snow to exit the roof, the blanket of ice backs up onto the roof, below the shingles, into the soffits, and then into your home’s interior.  Inconsistent roof temperatures and lackluster insulation and ventilation are responsible for the formation of ice dams.

Frozen Pipes

If pipes within your home’s walls freeze in the winter, it’s a red flag that your insulation could be improved upon.  Proper levels of insulation on your home’s exterior walls ensure that pipes do not burst, causing thousands of dollars’ worth of damage.

Wet Attic Insulation

During the wintertime, the stack effect causes exterior air to be drawn in through crevices in your basement and then rechanneled up the walls of your home.  The air leaves your attic through unsealed areas, but not before creating frost due to the temperature variances.  As temperatures heat up, the frost liquifies, ruining your attic insulation and creating mold.  The process of attic air sealing in tandem with correct insulation levels will curtail air from escaping the home.

Cold Air Coming in Through Wall Outlets

When exterior air can filter indoors, air infiltration occurs.  A common spot air can leak through in older homes is through the light switches and wall outlets located on exterior walls.  When this occurs, it’s a sign more insulation is needed.

"Jake Calleja’s service was prompt, knowledgeable, and thorough with excellent follow up. His manner was so pleasant—Lindus Construction is lucky to have him."

We have worked with Lindus to insulate above our garage. They did excellent work, timely, efficient, and clean. Super friendly. Now, in 2026 we had a leak in our ceiling so we called Lindus. Matt came out and went in the attic and found the source - not a roof leak or anything Lindus could fix...it was an HVAC issue. Matt was exceptional and professional. They did not charge me for the inspection or for finding the problem. They believe in building trust and long-term customers. I will continue to use Lindus because of these values."

"The work done was excellent and all of the workers that completed the job were thorough and easy to approach if needed. The communication before and during the project was great, as we knew when to expect work to be done.  We are very happy with the craftmanship on both projects (insulation and roofing).  We were very pleased with Lindus and the work we had done."

"Lindus carefully removed my LeafGuard® Gutters, reshingled my house and rehung the gutters all the while being careful of my new landscaping.  All of the crews were professional and easy to work with. I've used Lindus for attic insulation and gutters (even had them come to clean out my gutters once) and they have always been reliable with great customer service. I would not hesitate to recommend Lindus to any of my friends and family."
