"We needed to have someone remove the spray foam insulation from our attic. It was covering the ridge vent, all the boards and the joists and restricted airflow in our attic. We called several contractors and no one was willing to take on the job. Then we reached out to Brandon and he and his team were able to help us. They were all so professional and courteous. They worked tirelessly and meticulously to get the job done, and took care of all the cleanup, The results exceeded our expectations. We cannot thank Brandon and the team enough. 🫶"

Gas Fireplace Service questions, answered by experts

Chimney crowns may be stone, concrete, or metal but most crowns are made of concrete. It’s not recommended to build chimney crowns with mortar (which is different from concrete) due to it’s weaker composition (especially when exposed to the outside elements). Most chimney crowns are custom made to fit your home’s specific chimney.

You should use an angled brush to first paint the mortar lines, then go in with a high-density roller to evenly paint the bricks one at a time. You can also use a flat paintbrush to paint individual bricks, but a roller is faster and easier to use thanks to its longer handle and wider surface area for coating the bricks. To finish, go in with the paint brush for edges or hard-to-reach areas.

Fireplaces increase your home’s value by as much as 12%. If you're looking to increase your home's value, consider installing an electric fireplace insert or a custom electric fireplace. You can take freestanding or wall-mounted fireplaces with you when you leave, so they will have less of an impact on the value of the home.

If you have a gas fireplace, you should be able to see a vent exiting the fireplace directly to the outside of your home. You may also see gas lines leading to the fireplace. If the firebox in the fireplace is completely empty, it’s a wood-burning fireplace. There should be no burners or igniters in the fireplace.

A liter of bioethanol costs $11 and burns for around four hours, making it cost around $2.75 per hour to keep your bioethanol fireplace running. For comparison, natural gas costs around $0.50 per hour, and propane costs around $1.60 per hour. 

How much it costs you to run your bioethanol fireplace largely depends on how often you use it. Hypothetically speaking, if you run your fireplace for four hours a week year-round, you’ll go through one liter of biofuel per week or about $570 per year to run the fireplace.
