Insulation is Worth the Investment All Year Round

With the summer heat in full swing, homeowners with air conditioning have most certainly relied on its luxuries. But for all the comfort that cold air provides, running the A/C constantly over long periods of time can do a number on your energy bills. This is especially true if you live in a home with poor insulation. 

Most people think about the benefits of insulation during the winter but the truth is that a well-insulated home will benefit you all year round. As many of us know from school science class, heat rises, which is why the top floor and attic are always warmer than the bottom floor of a house. When an attic has no insulation, it will become significantly hotter than the outside temperature. Go ahead and touch the ceiling. If it feels warm, you can just imagine what the temperature is like above it. 

When your home doesn’t have enough insulation, those air conditioning units have to do double duty to regulate the temperature. Whether you have central air or window units, they are working overtime to keep you comfortable. All that extra effort gets reflected in your energy bills at the end of the month. 

There are several places where a home can get a boost in the insulation department. The attic is the place for the biggest improvement because it has the largest square footage and sees the greatest temperature changes. It’s also a place in the home that we tend to ignore because we’re not in there very often. Insulation options run from blowing loose fiberglass under the floor to laying batts between the floor joists. There are pros and cons to each option and they depend on the size of the house, the clearance space, and what the attic is used for. No matter which way you go,  a well-insulated attic is a pretty inexpensive home improvement and it will more than pay for itself in both energy costs and overall resale value.

In addition to the attic, ensuring that windows and doors are free of gaps and holes will help to keep your cold air inside. Check your door sweeps to see if they need replacing and seal any windows with caulk or sealing tape. Again, this is going to benefit your home both now and in the winter when you’re trying to keep the warm air in. 

Finally, for those of you with window A/C units, be sure to insulate around them. You can do this simply by using flexible foam to get a good seal on the top and bottom of the unit. Also, those side curtains aren’t there for nothing. Make sure they are tight-fitting and screwed in to help anchor the unit and keep the sides nice and secure. A window A/C that’s dropped in with no insulation is effectively only running at half power since so much of the cold air goes right back outside. It’s worth taking the extra steps to do it right.

Protecting Your Home From Attic Moisture

If your attic holds a lot of moisture, it can cause a lot of problems for the health of your home. Last week we took a deep dive into the most common culprits of humidity and this week we’ll be talking about how to remedy those issues. To get rid of moisture in your attic, you'll need to identify and address the underlying causes. Here are some steps you can take:

1. Find the source: If your attic humidity level is high, first determine what is causing the excess moisture. The most likely culprits are inadequate ventilation and insulation, roof leaks, or a plumbing issue.

2. Improve ventilation: Most houses that I visit do not have enough ventilation. It’s truly the best way to reduce moisture buildup and keep the temperature in your home more regulated year-round. 

3. Look for air leaks: Check for any gaps, cracks, or openings that might be allowing warm, moist air from your home to enter the attic. Seal these leaks with caulk or weatherstripping to prevent the transfer of moisture. It will also help if critters tend to find their way into the attic.

4. Insulate properly: Insulation helps regulate temperature and prevent condensation. Ensure your attic is adequately insulated to minimize temperature differences between the interior and exterior. Insulation is not just helpful for the winter months, it’s actually crucial year-round.

5. Assess for roof leaks: Inspect your roof for any signs of leaks or damaged shingles or if you’re not comfortable on a ladder, contact a professional. They will inspect both in interior and exterior of the home and be able to advise on appropriate repairs or replacements.

6. Address plumbing issues: If there are plumbing pipes or HVAC ducts running through your attic, check for any leaks or condensation. Repair any leaks and insulate the pipes or ducts to prevent moisture buildup.

7. Control humidity levels: Excessive humidity in your home can contribute to attic moisture problems. Use dehumidifiers in areas with high humidity, such as basements or bathrooms, to control moisture levels. Additionally, ensure your kitchen and bathroom vents are properly vented to the exterior, not into the attic.

8. Monitor and maintain: Regularly inspect your attic for signs of moisture or mildew. If you notice any issues, promptly address them to prevent further damage.

Attics are always tricky because they are so rarely occupied. However, if humidity levels increase the moisture will become a mold problem very quickly, which is hazardous to both your home’s health and yours. When in doubt, always contact a professional for guidance. A licensed contractor will be able to help remediate any problems both in the short and long term.

Attic Moisture Can Lead to Major Damage

As summer humidity begins to ramp up, it’s important to pay special attention to one of the most neglected areas of the home. Your attic can hold a lot of moisture and if it’s not insulated and ventilated correctly, that means major issues for you, the homeowner. In this two-part series, we’ll discuss how moisture can accumulate in the attic and what you can do to protect your home from serious damage. Let’s kick things off with a list of the major moisture-conducting culprits:

1. Insufficient ventilation: Without proper airflow, moisture from the living spaces below can become trapped in the attic, leading to condensation and elevated humidity levels.

2. Roof leaks: Damaged or deteriorating roofing materials can allow water to enter the attic during rain storms or snowmelt. Roof leaks can be caused by missing or cracked shingles, damaged flashing, or compromised roof seals.

3. Plumbing leaks: Plumbing pipes that run through the attic can develop leaks over time. Even a small drip or a slow leak can contribute to moisture accumulation in the attic.

4. Inadequate insulation: As hot and cold air collide, they will condensate or freeze. Without proper insulation and temperature regulation, it’s much easier for moisture to accumulate.

5. Blocked vents: Blocked or obstructed attic vents can impede proper airflow, preventing moisture from escaping. This can result in increased humidity levels and potential condensation problems.

6. Misdirected exhaust fans: If bathroom or kitchen exhaust fans are not vented directly outside, they can introduce warm, moist air into the attic space. This can cause condensation and moisture-related issues.

7. Poorly sealed attic access points: Gaps or insufficient sealing around attic access points, such as doors or hatches, can allow humid air from the lower floors to enter the attic, leading to moisture buildup.

8. Insufficient vapor barrier: A vapor barrier is a layer designed to prevent moisture from passing through walls and ceilings. If there is an inadequate or damaged vapor barrier in the attic, it can allow moisture to penetrate and cause problems.

It's important to address any water issues in the attic promptly to decrease the chances of mold growth, wood rot, or structural damage. Because most people access their attic infrequently, problems often don’t go detected until water starts showing up on the ceiling. Next week we will highlight several ways to protect your home from moisture before it's too late.
