Home Ventilation

A properly ventilated home is a key component to a comfortable living space and important for ensuring a safer home with lower energy bills. Ineffective air circulation can lead to overuse of unproductive fans, cranking high-cost heating, and encouraging mold.

CAZ team members are highly trained to target the hidden causes of these problems and make them right.

Proactive Solutions for Common Ventilation Problems

Whole House Fans

For the air inside your home to be healthy, it must move through the entire house. A whole house fan can significantly improve your indoor air quality by preventing stagnation. Here are a couple different fan options:

  1. One exhaust fan runs for a portion of the day. CAZ can calculate how long your exhaust fan should run based on how air tight your home is.
  2. Install a heat recovery ventilator (HRV) that runs all day. Exhaust Fans below will help you learn more about what HRVs can do for you!
Exhaust Fans

A home’s biggest sources of moisture and odor, exhaust fans are especially important in kitchens and bathrooms. When these ventilation systems aren’t working properly, they trigger rot and mold growth, harmful to your health and wallet.

Kitchen Exhaust Fans

Many kitchen stove-top fans simply blow air back into the room rather than ventilating the moisture from cooking. When moist air from cooking hits walls and windows, it can encourage mold growth. We recommend a fan that exhausts to the outside, keeping your walls and windows dry and mold-free.

Bathroom Exhaust Fans

Sometimes, bath fans need to go where there are no joists to attach.  This is one method of dealing with that.

It is critical to have a fan promoting air ventilation in each bathroom to prevent mildew, peeling paint, and other unpleasantry. You can do this simple test to see if your fan is doing its job:

    1. Turn on the fan and hold a piece of tissue up to it.
    2. If the tissue gets sucked up and stays pulled to the fan, your fan is promoting ventilation. If tissue falls, the fan needs adjusting or replacing.

For each bathroom, turn on the fan and head to your attic. Exhaust going straight into your attic will lead to moisture problems. CAZ offers a free consultation and free estimate to resolve these issues, save you money, and ensure a healthy home long-term.

Heat Recovery Ventilators

If you have a small, tight house, especially one that uses a heat source such as electric wall heaters, a heat recovery ventilator (HRV) can have great benefits. An HRV is an exhaust fan that removes the heat from the outgoing air and puts it into the incoming air. It is a simple and energy-efficient way to provide fresh air for your home. To see if these may be a good fit for you, get in touch for a free consultation.

Improving Ventilation to Protect your Foundation & Roof

Increasing Air Flow & Reducing Water Drips

Washington winters are rainy and damp. Water seeping through your home’s foundation, out of pipes, or into your roof happens under certain weather conditions that cause water vapor to be absorbed by porous building materials or freezing on the roof’s underside. It then condenses into a liquid that drips and can cause damage.

You can prevent this by having proper airflow in your attic and lower crawlspace. When the air is moving, it isn’t able to sit and let water condense into liquid form. People sometimes assume installing more vents is the best solution. However, creating more vents for wet air to come through can worsen the problem. When the ice crystals form and then later melt, enough water drips to encourage mold and cause structural damage. Read about a client that had this very problem and what we did to help them fix it. We’re happy to come assess your attic and crawlspace to ensure your foundation is as rock solid as it should be. If ventilation can be improved, we’ll discuss options to make sure they’re maximized.

Ventilation Project Costs & Time Frames

Each project varies, but we can provide a realistic average. If you’re looking to install a bath fan and already have one, the cost will average between $500 and $800. If don’t have a fan and are looking to have one installed, you can expect to pay between  $500 and $1000.

We also understand that time is money. It’s why our team is trained to provide you with high quality work at a quick, efficient pace. If you already have space set for a bath fan, it takes an average of a few hours to install. If your home needs our team to fully prepare the space, such as evaluating and cutting holes for the installation, the work will take approximately half a day.

To save you money, we suggest getting your inspections and installations in the spring time. With good weather for working and a less busy schedule for us, you will be paying a lower rate.
