4 Reasons to Clean Your Chimney

May 1st, 2017

Spring is finally here, and as we look forward to warmer weather, your fireplace is probably the last thing on your mind. Before you shift your thoughts to landscaping and skimming the swimming pool, give your chimney the attention it needs after a winter of use.

4 reasons to clean your chimney regularly

  1. Prevent fires. Over 24,000 house fires each year are started in the chimney. Cleaning your chimney 1-2 times annually helps eliminate soot build up, thus drastically reducing the risk of fire.

  2. Remove unwanted guests. No, we don't mean kicking your in-laws out or throwing your grown children to the curb! A dirty chimney makes a great home for birds, small animals, and pests. Cleaning the chimney is the best way to keep these unwelcomed visitors from making themselves cozy inside your home.

  3. Reduce the risk of Carbon Monoxide poisoning. Carbon monoxide is much more likely to creep its way into your home if you have build up in your chimney. Soot and ash can block the necessary vents which allow for chemicals to be released if your chimney is not properly maintained.

  4. Prevent smoke damage. Along with blocking access for chemicals to leave, a dirty chimney also makes it more difficult for smoke to rise. When there is blockage involved, the smoke will have no other route than back down the chimney and into your home, which can lead to damage within the fireplace surround as well as several health concerns.

Before you retire your fireplace for the season, give your local chimney sweep a call. If nothing more, it will help you celebrate spring with peace of mind and take one item off of your to-do list when the weather cools down again in the fall!

Fireplace Safety 101

November 17th, 2016

Fireplaces and chimneys are to blame for 42% of home heating fires, and ‘tis the season for cozying up near the glow of embers. With cold weather approaching, taking these three steps will help you stay safe and warm this winter.

  1. Check for damaged brick and mortar. Inspect your chimney and firebox for damages or cracked bricks and deteriorating mortar. If you find issues, click here to build new firebrick using Heat Cast 40.

  2. Sweep it out. Hire a chimney sweep at least once per year to clean out the chimney and inspect for any damages. While you have them there, you might also want to install a chimney cap to keep out any unwanted birds, critters, or debris.

  3. Build smart. Building the fire itself is almost as important as building your fireplace. Place larger logs towards the back of your firebox and always use kindling or smaller logs to ignite the flames rather than flammable liquids. A wire mesh screen or glass fireplace doors are also recommended for optimal fire safety.

If you happen to discover damage to your firebrick or mortar, check out our Youtube videos for simple fixes using Heatstop products to get your home winter-ready. Keeping your fireplace clean and free from cracks is the best way to maintain peace of mind while celebrating the season for peace on earth!

Having a Moment: Outdoor Ovens

May 20th, 2016

Outdoor ovens are having a real "moment" lately. From backyard barbeques to celebrity soirees, you're bound to see at least one outdoor oven at some point this summer. 

Along with their attractive display, outdoor ovens are appealing to the tastebuds too – with so many recipes for delicious homemade breads and gourmet pizzas, any house with an outdoor oven is sure to be the "go to" spot on warm summer nights! 

Wood-fired brick ovens and pizza ovens have been with us since early ancient civilization, reaching its modern form in ancient Rome. The ovens have gone through many changes over the years, but the original method of using them has essentially remained the same. The most recent change in brick pizza oven design, and possibly the most important in terms of their evolution, has been the use of modern refractory and insulating materials, allowing pizzas and breads to cook in around 45 minutes rather than the traditional 2-3 hours, thanks to improved heat-holding characteristics.  

If you're in the market for landscaping work this summer (or even if you're not!), consider adding an outdoor oven as a focal point to your entertaining space. Your friends and family will thank you and we promise you won't regret it. Just be sure to keep plenty of yeast on-hand for when company happens to be "in the neighborhood!" 

Not sure where to begin? Shop the full line of outdoor piza ovens here, choose a facing material, and don't forget the HeatStop mortar

Measuring is Key - Determining How Much Heat Stop Product You Need

December 1st, 2015

Whether it's building a bake oven, repairing a chimney or working on fire pits, fireplaces, furnaces or kilns, using the right amount of Heat Stop product is critical. Heat Stop is an important component of many successful projects, but using the product properly is essential to achieving the desired result — and in obtaining the best product performance.

Successful mortar projects rely on successful product use.

In 40 years of using Heat Stop products, I've had many questions about product measuring and use - here are my top four tips and lessons for measuring and using Heat Stop products in your projects:

1. No two projects are the same. There are several factors that affect the amount of Heat Stop product needed for your project. These of course include the type of project being done, joint mortar thickness used, and waste, among other factors. But most importantly - each of these factors varies from person to person. It's important to understand the specifics of your own project and habits to determine the steps and use that will lead you to success.

2. Understanding the basics of product use is key. Before you can consider the variables affecting your project, you should understand the basics. Here is a "quick guide" to Heat Stop measurement basics:

In general, Heat Stop premix and Domestic Fireplace Mortar premix, which are refractory mortar products, should be applied with a maximum joint thickness of 1/16-1/8". Heat Stop II and Heat Stop 50, which are dry refractory mortar products, should be applied with a minimum thickness of 1/16-1/8", and may be applied in thicker joints as desired. For each of these products, installers will need approximately 50 lbs. of product to lay up 100 firebrick (assuming the joint thickness is 1/16-1/8").

Heat Cast 40 should be applied 2" thick when used to cast shapes or installed as a hearth in a heat chamber. Installers will need approximately 20 lbs. per square foot when applied 2" thick.

Insul Stick, which is used to parge over firebrick in a smoke chamber or for exterior applications, should be applied 1/4 to 1/2" thick. Installers will need approximately 2.5 lbs. per square foot when applied 1/2" thick.

Finally, Insul Cast, which is a backup insulating product that can be applied under the hearth or over the dome in a fire pit or bake oven, should be applied with a minimum thickness of 2". Installers will need approximately 6 lbs. of product per square foot when applied 2" thick.

3. Pay attention to the details. While following the guidelines above is the best way to ensure you're using the correct amount of Heat Stop product, paying attention to smaller steps and details is also important. Heat Stop pre-mix products can be used as is, but we recommend installers give the product a thorough mix or stir before using. Depending on your specific needs or preferences, you may want to add a little water to thin the product consistency, but you'll then need to mix the product thoroughly again before using.

4. Be ready for extenuating circumstances. Refractory mortar products may take longer to dry if the joints are thicker than 1/8", and/or if conditions are extremely humid (which occurs in certain climates or after rainfall in many areas). To enhance the drying in such conditions, open the damper, place a fan in front of it, or use other means to get some air or heat passing by the installation.

Consider and follow these tips, and you'll be well on your way toward a successful project!

Are You Using the Right Refractory Mortar Product for Your Project?

October 29th, 2015

For more than 40 years, Heat Stop products have been used across the country. As the years have progressed, we have added several Heat Stop products to the mix; however, using the right Heat Stop refractory mortar product is critical to the success of your project.

Are you using the right Heat Stop product?

With such a range of products available, it can be easy to confuse Heat Stop mortar products' intended uses with the uses of Heat Stop castable products — or even other homemade formulations (including fireclay).

Why it's important to choose the right Heat Stop product

It's extremely important to choose the right Heat Stop product for your projects. Heat Stop products that are not applied correctly may not achieve the intended results. Here's an example: Heat Cast 40 is a castable product intended to be used instead of firebricks or to make special shapes. It should be applied 2" thick. If it is not applied thick enough, it may not be structurally sound for the intended application. Applied correctly, it is of course a very sound product.

Similarly, Heat Stop premixed or Domestic Fireplace Mortar are products intended for interior (no moisture) applications. Using them in high moisture applications may not achieve the intended results. For exterior applications, it's important to only use Heat Stop 50 or Heat Stop II.

Top usage mistakes with Heat Stop products

Choosing the right product is essential, but once you have the right product for your project, proper usage ensures the success and safety of your project. Here are the top three usage mistakes to avoid with Heat Stop products:

  1. Not mixing the Heat Stop premix or Domestic Fireplace Mortar products thoroughly before use. Just because they are labeled "premix" doesn't mean they couldn't use a little stir!
  2. Making mortar joints too thick when applying Heat Stop premix or Domestic Fireplace Mortar (joints should be 1/16" - 1/8")
  3. Using premix products (Heat Stop premix or Domestic Fireplace Mortar) for interior applications.

When using Heat Stop products, be sure to understand the building codes in your area, and follow them. Pay special attention to codes that require the use of refractory mortar (code ASTMC-199), and learn about good quality masonry practices. Follow these suggestions and avoid the mistakes noted above, and your project will be on its way toward successful completion.
