What’s Causing My House’s Foundation Cracks?
While your home’s exterior is designed to be air-tight, cracks and holes can form. Your home’s foundation cracks can result from wear and tear and be visible as gaps where pipes and lines pass through the walls. No matter what the reason, those cracks or holes can let the air in and out.
How to check for foundation cracks
Inspect areas where gas and electric lines enter your home. Look for gaps or holes. If there are openings, cold air is likely leaking into your home from outside through these gaps.
CAUTION: If you find exposed wires or a broken conduit/pipe, stop and call your electrician. Do not touch damaged electrical components.
Inspect the windows and doors in your home. There should be no gaps between the door or window and its frame. If there are holes, cracks, or gaps, air from the outside can get in and make it harder to keep your temperature where you want it.
Old, single-pane windows can also transfer hot or cool temperatures from outside, even if there are no gaps. If your windows are old, you may want to consider upgrading them to more modern, double-pane windows that help to insulate.
Use a proper ladder to access the hatch to your attic. Bring a flashlight and wear a dust mask or respirator when climbing into the attic. Push away some insulation (if you have fiberglass insulation, wear gloves or use a tool to move it aside). Look for electrical lines drilled into the interior wall top plates. If the wood framing, electrical lines, and plumbing pipes are not sealed with foam or mastic, your insulation won't be air-tight.
CAUTION: Be very careful anytime you enter your attic. Attics are tight, enclosed spaces and you can get stuck or injured. Make sure that you're able to move freely and aren't stepping on any flooring that may collapse. While moving around in the attic, be aware of any exposed nails. If it's summer, attics can reach temperatures of 140℉. Don't go into the attic if you're sensitive to high temperatures and don't stay in the attic for long periods of time. Lastly, attic insulation fibers shouldn't be inhaled. Wear a dust mask or respirator whenever you're around exposed insulation.
