Seal leaks with caulk and weatherstripping, add shrink film, and close shades at night. A PNNL-cited test found 17-36% daily heating savings.

Luxury vinyl plank is usually the safer pick for baths, kitchens and basements. Laminate suits dry rooms. Both click together as floating floors.

12 steps to cut winter electric bills: air sealing saves about 15% on heating and cooling, LEDs use up to 90% less energy, plus filters and setbacks.

Fill nail holes with compound, cover medium holes with a self-adhesive mesh patch or crossed tape, and cut out and replace larger damage.

Prevent ice dams by keeping the roof cold: seal attic air leaks, add continuous insulation, and ventilate from soffit to ridge.

Keep your refrigerator at or below 40°F and your freezer at 0°F. ENERGY STAR suggests 35-38°F for the fridge. Check with an appliance thermometer.

Hard water stains are calcium and magnesium deposits. Dissolve them with white vinegar or citric acid, a soft pad, and a squeegee to prevent them.
