Building your own outdoor fireplace is a rewarding DIY project that adds value and ambiance to your backyard. NailIt helps you estimate the total materials cost—bricks, mortar, stone, metal components, and more—so you know exactly what to budget before you start. No labor costs included; this is what you'll spend on supplies.
Estimated DIY materials cost for total materials — you supply the labor. Prices vary by region and brand.
This is an advanced project — be honest about your skills, tools, and time before going DIY. The pro figure is a rough rule of thumb (labor on jobs like this often runs 1–2.5× the materials) — always get real quotes. It is not a NailIt estimate.
NailIt estimates materials only, so here is the honest version of the labour question rather than a number we cannot stand behind. Installed, this job commonly lands somewhere around $2,400–$15,750 — that is the materials range above with labour applied at the rough 1–2.5× multiplier trades typically work to on jobs like this. It is a sanity check for reading a quote, not a NailIt estimate and not a substitute for a real one.
What actually moves that number: your region and local labour rates, access and prep work, whether a permit and inspection are involved, disposal of the old material, and how much the crew has to work around your schedule. For this project most homeowners are better off getting quotes — see the gauge above. Always collect three written quotes from licensed, insured contractors and compare what each one includes — how we handle pricing.
