How Does a Fireplace Smoke Guard Work? Basics Explained

A fireplace smoke guard is a metal strip that attaches to the top of your fireplace opening to help improve the chimney’s draft and prevent smoke from entering the room. By reducing downdrafts, you improve your fireplace’s performance and prevent smoke-related issues.

In this post, we’ll examine smoke guards in depth, including their mechanics, benefits in terms of draft and smoke spillage, practical tips for choosing the right size and style, and straightforward installation.

This should help you make an informed decision about fireplace smoke guards. Ultimately, we want to help you enjoy your time by the fire, cozy and smoke-free.

How Does a Fireplace Smoke Guard Work?

A fireplace smoke guard reduces the fireplace opening, improving the draft and preventing smoke from entering the room. Smoke issues often occur because the fireplace opening is too large in proportion to the chimney flue size. 

By reducing the size of the fireplace opening, you help balance the ratio between the fireplace size and the chimney flue size, resulting in a better upward draft of smoke and gas.

Sometimes, weather conditions can cause down-drafts, where air is pushed down the chimney into the fireplace, causing smoke to enter the room. A smoke guard can prevent this from happening by altering the airflow at the opening of the fireplace, reducing the impact of down-drafts.

Benefits of Using a Smoke Guard

A fireplace smoke guard offers plenty of key benefits:

• Less smoke spillage – One of the main benefits of having a smoke guard is less smoke spillage. When you improve the fireplace draft, you ensure that smoke draws up the chimney more effectively, keeping your living space free from smoke.

• Prevents downdrafts – Smoke guards prevent down-drafts, which cause smoke to enter the room. 

• Better safety – Smoke guards reduce smoke spillage into the room, which means there is less risk of smoke inhalation and better air quality inside your home. 

• Better fireplace efficiency – A better draft means better air supply to the fire, which results in an overall efficient fireplace.

• Easy to install – Smoke guards are easy to install and require no major modifications to your existing fireplace. 

• Cost-effective – A smoke guard is more cost-effective than other repairs to address smoke issues (e.g., extending the chimney and adjusting the flue size). 

• Aesthetically pleasing – Smoke guards come in different styles and finishes, so you’re sure to find one that complements the look of your fireplace.

• Versatile – Smoke guards can be used on both wood-burning and gas fireplaces, making them a versatile solution.

Fireplace Smoke Guard Installation Steps

Here is a step-by-step guide to help you install your fireplace smoke guard.

You will need:

• Fireplace smoke guard (the right size for your fireplace)
• Measuring tape
• Pencil or marker
• Drill
• Screws (provided with the smoke guard)
• Adhesive 
• Level 

Step 1: Measure your fireplace

Before you buy a smoke guard, measure your fireplace. Take the width of your fireplace, as it is the same width you need with your smoke guard.

Step 2: Clean the fireplace area

Clean the area where you’ll be attaching the smoke guard. It should be free of soot and debris. This will help the adhesive bond better or allow for a clean area for drilling.

Step 3: Mark the position

Hold the smoke guard in place at the top of the fireplace opening where you plan to install it. Use a level to ensure that the smoke guard is perfectly horizontal. Using a pencil or marker, lightly mark the position of the smoke guard on both ends. If the smoke guard came with screws, also mark the drill holes. Again, use the level to see that the marks are even.

Step 4: Prepare for attachment

For adhesive attachments, apply it to the back of the guard according to the manufacturer’s instructions. For smoke guards that require drilling, pre-drill the holes that you’ve marked. Just be sure not to drill too deeply, or you’ll damage the fireplace.

Step 5: Attach the smoke guard

For adhesive attachments, carefully align the smoke guard with the marks you’ve made and press it firmly in place. Hold it for a few seconds to ensure a strong bond. For screw attachments, align the smoke guard with the pre-drilled holes and then use the drill and screws to secure the smoke guard in place.

Step 6: Final checks and clean up

Once the smoke guard is attached, gently tug it to ensure that it’s securely attached. If you use an adhesive, wait for it to cure fully before using the fireplace. You can then start cleaning your work area and remove any marks you made for alignment in the fireplace. 

What Should I Consider Before Buying A Smoke Guard?

You need to consider several factors when you buy a smoke guard. Here are the top key considerations.

Size and fit

Smoke guards are available in different sizes, so you’ll want to select one that fits your fireplace opening correctly. The guard should cover the top of the opening without extending too far to the sides.

Material and durability

Your smoke guard will be exposed to high temperatures, so pick heat-resistant materials. Steel or other metal smoke guards are a popular choice. Research and read reviews to see if the model you’re considering is indeed effective at eliminating smoke spillage. 

Aesthetics 

Because the smoke guard is a visible addition to your fireplace, you’ll also want to consider its design and color. You want it to match or complement your living space. You can choose different finishes, including black, brass, pewter, bronze, stainless steel, copper, and matter. Some manufacturers can make custom colors to match your needs. 

Installation method

Smoke guards are often installed in two different ways, by adhesive or screw. Choose the option that you’re the most comfortable doing. Some models have easy, tool-free installation, while others require drilling into the fireplace.

Smoke guards designed to be adjustable also exist. They have spring-loaded mechanisms that allow you to fine-tune their position for the best performance. This can be a useful option if your fireplace has non-standard dimensions. 

Price

Compare prices among different brands. You want a brand with a reputation for durability and effectiveness. Don’t settle for the cheap kind, as it may not always be the best in the long run. 

Limitations and alternatives

While smoke guards can significantly reduce smoke spillage into the room, there are situations where they might not fully resolve the problem. For instance, if there is an obstruction in the chimney or the flue is not correctly sized for the fireplace, you may need to go for alternative solutions such as chimney caps or dampers or contact a professional chimney repair company for help.

Fireplace Smoke Guard Cost

The cost of a fireplace smoke guard can vary depending on factors such as size, material, finish, and brand. 

Prices typically range from $50 to $100 for standard sizes and materials like steel with a basic finish (black or matte). 

Mid-range models have more size options, different finishes (brass, pewter, or antique finishes), and possibly adjustable features. These types can range from $100 to $200.

High-end models allow for custom sizes, finishes, and even decorative designs. They’re also made from premium materials such as copper or high-grade steel. Prices for these can go upwards of $200 to $300.

Also, consider whether you will install a smoke guard yourself or hire a professional. Installation costs would be an added extra. Shop around for different prices from different retailers and read up on reviews to check for the product’s durability and effectiveness.

Conclusion
