A lot of people in the American South enjoy outdoor barbecue cooking, so there is a lot of demand for getting an outdoor fire pit installed in the first place. This means that if you are in the area, you will find plenty of contractors who are up to the task, who have a lot of great and relevant experience, and who can guide you every step of the way.
However, the fact that there is a lot of demand for fire pit installation these days also means that people are going to be in a situation in which they are forced to work around the contractor’s schedule. If the contractor is working on a lot of busy projects at any given time, he or she is probably going to try to charge more for the same service. Otherwise, you will be in a situation in which you have to wait a long time for the fire pit to get finished. If you want the pit in time for the summer, it’s best to try to get it installed during the off-season for the contractor. Houston TX tends to be warm all year long, which is definitely a good thing. However, this also means that finding an exact off-season for a contractor can start to get tough.
For a custom build, contractors will probably charge between fifty and a hundred dollars per hour for your outdoor fireplace or your fire pit. The more sophisticated the stonework is and the more detailed it all is in the first place, the more it’s going to cost you. 
During the busiest seasons for the contractors, they are probably going to charge twice as much, so you will be paying at least a hundred dollars an hour for the labor.
The number of billable hours will certainly vary, of course. However, people can often expect to pay between 2,000 and 30,000 dollars for their fireplaces and fire pits outside. In some cases, people are going to be in a situation where the cost is much higher than they would expect. The materials will cost a lot of money, but a lot of the costs are going to be due to the billable hours of the contractors.
You might be interested in cutting down on the costs by trying to do it all yourself. However, unless you’re an expert, this is going to be difficult at the best of times. You have to try to plan ahead for a project like this to be expensive.
