If you envision cozy winter evenings in front of the fireplace, installing a pre-fabricated gas fireplace unit is an economical and enjoyable solution. However, before you can snuggle up in front of the fire, there are several factors to consider and questions that require answers before starting the project. Here are the top gas fireplace questions to go over with a contractor when planning your project. 

1. When do you need this project completed?

Whether you're replacing an existing gas fireplace, upgrading from a wood-burning model, or installing a unit for the first time, installing a prefabricated gas fireplace can take as little as a few hours or as long as several weeks. Talk to a gas fireplace pro early in the planning stages about scheduling your project, its overall timeline to completion, and the steps necessary for installation success. 

2. What best describes your fireplace installation?

While your new gas fireplace is prefabricated, which takes care of a couple of variables, your contractor will still need to know whether your project is replacing an existing unit, a completely new installation, or something in between. The type of installation you're looking for will significantly affect the cost of the project, and your gas fireplace pro will need to know the information to obtain the correct permits and make appropriate plans. 

3. Where will your fireplace be located?

While you may be able to use your home's existing chimney or reuse the venting from an existing gas fireplace, your contractor will need to know specifics about where you plan to put your fireplace. An inspection will be necessary if you wish to use one of these options to install a new prefabricated gas fireplace. Depending on the location of the new fireplace in your home and the condition of the existing venting options, it's often better, and potentially more cost-effective, to install all-new components.  

4. What is your gas fireplace budget?

Depending on your tastes and wishes, the full installation cost of a prefabricated gas fireplace can range from under $1,000 to well over $10,000. Discussing your budget early in the planning stages with your contractor is essential for a couple of reasons. First, your contractor will know not to plan for something that is out of your budget. Second, your contractor can work within your budget to help maximize the value you get for your money. 

5. What are the safety considerations of owning a gas fireplace?

Before installing any fireplace in your home's living space, if you have pets or young children, discuss the safety considerations of your installation. Additionally, even if you don't have pets or children, talk with your installer about the maintenance and safety needs of your new pre-fabricated gas fireplace.
