How Much Lava Rock Do I Need?

from 251 reviewsRoyal Fire Pits broadly, and Jordan specifically were such a total and complete DELIGHT to work with!!!! After MANY months of getting a runaround and grotesque price gouging from local fireplace services, I found Royal Fire Pits online and gave them a call just to order a stove. I am a novice at this, but Jordan was such an expert and had such knowledge and patience, and steered me to the right stove for my space, right away. He was even happy to work with my contractors timeline and hold off delivery until the contractor was in place for my job. Because ordering the stove was so problem free, I decided to call back for the considerable piping and chimney material I would need for the install. Once again, Jordan was supremely organized and knowledgeable and gave me a price almost HALF of what local places were charging. The delivery was problem free, and any questions I had, Jordan was available almost instantly. All in all, ordering the stove and all of the piping from Royal Fire Pits saved me close to $8,000 and the customer service is on par with what you expect from an American Express or Disney experience. I have renovated the whole house and Royal Fire Pits was the only experience that was friendly, professional, efficient and reasonably priced. I am SO glad I found this company, and will 100% use them for my next wood stove project. Thanks so much!!!

Jordan provided great customer service and went the extra mile to ensure a successful delivery. 2 thumbs way up!

THE BURNER IS WONDERFUL AND EASY TO INSTALL. JORDAN HAS BEEN WONDERFUL WORKING WITH THROUGH ENTIRE PROCESS

This beautiful Bordeaux Encore wood burning stove was put in place yesterday with the help of a few friends. Really appreciate your help and efficiency in streamlining this order. Royal Fire Pits is fortunate to have Jordan as a representative. Your knowledge and competence about the Vermont Castings product was evident and appreciated. Thank you again for your assistance and followup. We Love it.

Excellent service, very helpful, thoughtful and friendly representative. Very good price and the delivery was even quicker than the offer from my local dealership. I am recommending this dealer without any objections.

Very natural looking flames, especially with the ceramic log set. Shipping was quick and overall service was great.

Royal Fire Pits was great to work with. Product delivered without a handle though. I'm sure Jordan will be sending me one shortly.

Quality equipment

I bought a Vermont Castings Intrepid wood burning stove and dealt with Jordan the entire time. He was a huge help throughout the process also helping me order all the piping I would need to install. Loved the no tax and free shipping as well!
Seem solid and will work well

When making a purchase this large on the internet and being new to a new company I was definitely a little concerned about the product arriving. However sooner than expected and packaged like a professional company I quickly learned Royal fire pits was no joke. Checking out was simple and communication about it shipping was never a question. Construction is still under way on the fire pit so it has not been fired up yet, but if I need any additional products I will certainly not think twice about contacting Royal Fire Pits. Thanks again for a great experience.

Jordan was excellent to work with. He answered all my questions and always got back to me if he had to research a question! The no sales pitch, no pressure is absolutely true and if we were located closer to him, I would thank him personally. Jordan, THANK YOU AGAIN!
We had several questions that were answered respectfully. They made it easy to order and helped every step of the way.

Received as promised and in good external condition. The delivery driver delivered it inside my garage. It will sit there waiting for the installer to come in mid February. We'll open the package then and have a chance to give it a close up examination and see how it works.

Great company to work with.
