Turn your fireplace dreams into reality!
We will help you design a safe, yet aesthetically beautiful semi-custom or custom fireplace for your indoor or outdoor living space. You provide the opening size, style and application and we will handle the rest. Sizes within the parameters of 38.5” tall and 120” wide have been tested to UL127 standard and listed by PFS TECO. When you have a project outside of those sizes we make the units to meet the NFPA211 standard. Past projects include fireplaces up to 30 feet wide and some with 6-foot-plus opening heights. With Mason-Lite custom fireplaces, the possibilities are endless.
For projects that demand efficiency without sacrificing quality, Mason-Lite also offers semi-custom fireplace units. These designs feature standardized components with readily available drawings, reducing lead times and simplifying the ordering process. Semi-custom units still offer flexibility in size and style within pre-engineered parameters, making them an ideal solution when your project requires quicker turnaround or repeatable designs. With Mason-Lite’s semi-custom options, you get the same trusted performance and elegance—delivered faster and with fewer variables.
Mason-Lite’s fully customizable fireplaces meet NFPA 211 requirements; there is no customizing in the field because we ship your fireplace as a pre-cut, complete kit. Custom fireplaces are available in wood-burning, gas burning, and vent-free; and with linear, single-sided, see-through, corner, 3-sided, and 4-sided options. Choose Mason-Lite’s optional Virginiana Logs systems or Opalescence Linear Burner systems or maybe you’ve chosen your own interior firebox media to finish your beautiful and unique fireplace.

FAQs
-
Do multi-sided fireplaces need power venting?
In many cases this is necessary. The Mason-Lite team can help determine when fans are necessary. When in doubt, we highly recommend you pre-wire for power venting.
-
Do Mason-Lite custom fireplaces have brick panel options?
We can accommodate in limited sizes only. Otherwise, you will need to have the firebrick hand-laid by a mason.
-
Can I do any size custom I’d like?
Generally, yes. We just need the dimensions. Please fill out our custom quote form.
-
Do I need an angle-iron?
Yes. You will need to buy it locally. Our Mason-Lite team can help you determine the correct size.
