How to Keep Your Basement Dry During the Winter Thaw

We’ve had weeks of below-zero temperatures and a solid foot of snow parked in our yards. Now the forecast is shifting into the 30s and 40s, and a whole lot of melting is happening. While that feels like progress, it’s actually one of the riskiest times of year for basement moisture problems.

Why? Because all that snow has to go somewhere, and if your home isn’t ready, it often heads straight for your foundation. So here’s how to stay ahead of snowmelt season and keep your basement dry while winter makes its messy exit.

Start with the Foundation

Your foundation is ground zero when the snow starts to melt. Take a walk around your home and look closely for cracks, gaps, or areas where water could sneak in. Even hairline cracks can become entry points once meltwater builds up.

Seal visible cracks with a quality waterproof masonry sealant, and pay attention to where the ground meets your foundation. If the soil has settled and now slopes toward the house, melting snow will follow that path right inside. Long-term, regrading may be needed, but even small fixes now can make a difference.

Clear Snow Away, Especially Now

Snow removal isn’t just about shoveling walkways. As temperatures rise, snow piled along the foundation, bulkhead, or basement windows becomes a slow-release water source.

Pull snow away from:

• Foundation walls

• Basement windows and window wells

• Bulkheads and exterior stairwells

This gives meltwater room to disperse instead of pooling against your home. Think of it as redirecting traffic before there’s a pileup.

Make Sure Gutters Can Handle the Thaw

When snow melts from the roof, gutters and downspouts become critical. If they’re clogged with leaves, ice, or debris, water will overflow and dump straight at your foundation, exactly where you don’t want it.

Check that:

• Gutters are clear and securely attached

• Downspouts are open and directing water several feet away from the house

• Ice hasn’t pulled gutters loose or changed their pitch

This is one of the most common causes of basement water during a thaw and one of the easiest to prevent.

Don’t Ignore Window Wells

Basement window wells love to collect snow, ice, and debris. When everything melts at once, those wells can fill up like a bathtub and leak straight through window frames.

Clear them out now and make sure the drains at the bottom are open and functioning. If you’ve had issues in the past, window well covers can help keep snow and water out altogether.

Prepare from the Inside, Too

If moisture does get in, you want to limit the damage. Interior waterproof coatings on basement walls can help reduce seepage, and a dehumidifier can keep humidity levels under control during the thaw, when damp air is common.

Condensation plus cold surfaces equals moisture, so controlling humidity helps prevent mold and musty smells from taking hold.

Test Your Sump Pump Before You Need It

Snowmelt can overwhelm a sump pump fast. Now is the time to test it, not during the first warm rain on top of melting snow.

Pour water into the sump pit to confirm it turns on, pumps efficiently, and drains properly outside. Clear any debris, and make sure the discharge pipe isn’t blocked by snow or ice.

If your sump pump fails during a thaw, water can rise quickly and cleanup is never fun.

A winter thaw might feel like relief, but it’s also when many homeowners discover problems they didn’t know they had. A little attention now can save you from water damage, mold, and expensive repairs later.

What You Don’t See Can Affect You When It Comes To Winter Air Quality

When winter settles in, most of us do the same thing: shut the windows, seal the drafts, and crank the heat. It’s great for comfort and energy efficiency, but not always great for the air we breathe. With homes closed up tight for months at a time, indoor air quality can quietly take a hit, leading to discomfort and even health concerns.

The good news? A few smart habits and simple upgrades can make a noticeable difference.

Why Indoor Air Quality Suffers in Winter

Cold weather means less fresh air circulating through your home. At the same time, heating systems kick into high gear, stirring up dust and other particles that might otherwise stay settled. Common indoor pollutants during winter include dust, pet dander, mold spores, and volatile organic compounds (VOCs) released from cleaning products, paints, and furnishings.

When these pollutants build up, people may experience headaches, fatigue, sinus irritation, or respiratory issues - symptoms often lumped under the term “sick building syndrome.” If you’re feeling off all winter, your indoor air might be part of the problem.

Practical Ways to Improve Winter Air Quality

Let Fresh Air In, Yes, Even in Winter

You don’t need to leave windows wide open. Short bursts of fresh air, just a few minutes at a time, can help flush out stale indoor air. Using kitchen and bathroom exhaust fans also helps remove moisture and airborne contaminants right at the source.

Keep Humidity in the Sweet Spot

Indoor humidity should hover around 40–50%. Too much moisture encourages mold growth, while air that’s too dry can irritate your nose, throat, and skin. A humidifier or dehumidifier can help keep things balanced, especially in older homes.

Stay on Top of HVAC Maintenance

Your heating system keeps you warm and moves air throughout your home. Change filters every three months and schedule annual maintenance to keep things running efficiently. Dirty filters and neglected systems can spread dust and allergens instead of trapping them.

Use Air Purifiers Where You Spend the Most Time

A quality air purifier with a HEPA filter can significantly reduce airborne particles like dust, pollen, and pet dander. Units with activated carbon filters also help absorb odors and chemical fumes. Bedrooms and living areas are usually the best places to start.

Add a Few Low-Maintenance Houseplants

Some plants help improve indoor air quality while also making your home feel more alive during the gray winter months. Snake plants, for example, are hardy, low-maintenance, and known for their air-filtering benefits.

Choose Cleaning Products Carefully

Many conventional cleaners release VOCs that linger in indoor air. Switching to natural or low-VOC products can reduce chemical exposure. When stronger products are necessary, proper ventilation is key.

Install and Maintain Gas Detectors

Carbon monoxide and radon are invisible, odorless, and potentially dangerous. Make sure detectors are installed and functioning properly, and test them regularly, especially during heating season.

Keep Dust Under Control

Regular dusting and vacuuming go a long way. Using a vacuum with a HEPA filter prevents allergens from being kicked back into the air while you clean.

Go Easy on Scents

Candles, plug-ins, and air fresheners may smell nice, but many release VOCs. If you use them, do so sparingly and make sure rooms are well ventilated.

Breathe Easier All Winter Long

Winter doesn’t have to mean stale air and stuffy rooms. With a few proactive steps, you can protect your indoor air quality, improve comfort, and create a healthier home environment for everyone under your roof.

Keep Your Home Cooler with These Summer A/C Tips

As temperatures and humidity rise, many homeowners turn up the air conditioning to stay comfortable. However, overworking your A/C system without proper maintenance can lead to reduced efficiency, an increased likelihood of mold, and potential water damage. Here are several ways to stay cool while keeping your house’s health in check.

1. Replace or clean your air filter regularly.

A clogged air filter can reduce your A/C’s efficiency by up to 50%. Check your filter monthly and replace or clean it as needed. A clean filter improves airflow, helps the unit cool more effectively, and reduces the amount of dust, pollen, and mold in the air. When selecting a filter, consider its MERV (Minimum Efficiency Reporting Value) rating. Residential units typically use filters with a MERV rating between 1 and 12. Higher ratings trap smaller particles and can improve indoor air quality.

2. Seal gaps around window units.

Window air conditioners can allow warm, humid air into the home if not properly installed. Use foam insulation or foil tape to seal gaps around the unit. This reduces energy loss and keeps your space cooler. Materials are inexpensive and available at most hardware and home improvement stores.

3. Use a programmable timer or smart plug.

Air conditioners use a significant amount of energy. Avoid running your unit at full power when you’re not home. A programmable timer or smart plug can adjust the temperature while you’re away and return it to a comfortable level before you arrive. This helps reduce wear on the system and can lower energy bills.

4. Check attic insulation and ventilation.

Poor attic insulation can make it harder to keep your home cool, especially on hot days. If your ceiling feels warm to the touch, it may indicate that there is insufficient insulation. Improving insulation and ventilation helps maintain indoor temperatures and reduces the strain on your A/C system. This also benefits your home during the winter months.

5. Inspect your system for leaks.

Water leaks from central A/C units often result from a cracked drain pan, clogged filter, or a blocked condensate line. These issues can lead to water damage in ceilings or walls. If you notice any signs of leaking, turn off the system and inspect these areas promptly. Addressing small issues early can prevent costly repairs later.

Staying cool doesn’t have to come at the cost of high energy bills or home damage. With a few simple checks and low-cost upgrades, you can improve your air conditioner’s performance and keep your home comfortable all summer long. Regular maintenance now can also extend the life of your system and help prevent unexpected breakdowns when the heat is at its worst.
