Stone Age fireplace kits typically cost about $3,000-$8,000 for the kit alone, while a professionally installed outdoor fireplace often totals $8,000-$20,000. Final price depends on fireplace size, chimney configuration, exterior finish, site preparation, delivery distance, and local masonry labor.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Stone Age kit | $3,000 | $5,500 | $8,000 | Kit size and included components affect price |
| Installation labor | $2,500 | $5,000 | $8,500 | More for complex assembly or difficult access |
| Foundation and site work | $500 | $1,500 | $3,500 | Depends on base, grading, and removal needs |
| Complete installed project | $6,500 | $12,000 | $22,000 | Before unusual landscaping or extensive masonry |
What Stone Age Fireplace Kits Cost Before Installation
Most buyers should budget $3,000-$8,000 for a Stone Age kit, with many standard configurations landing near $4,500-$6,500. A smaller, simpler fireplace generally costs less than a wide model with a taller chimney or additional components. These are planning ranges, not fixed manufacturer list prices; dealer pricing, freight, package contents, and regional availability can shift the quote.
The kit price is only one part of the finished-fireplace budget. A kit commonly includes precast masonry components for the firebox and chimney, but buyers should confirm which hearth, smoke chamber, cap, and connection materials are included. Decorative veneer, mortar, flue accessories, foundation work, and labor may be quoted separately.
With professional installation, a straightforward project using a standard kit and accessible site often totals $8,000-$15,000. Larger installations with upgraded stone facing, a tall chimney, excavation, or substantial hardscape work can reach $18,000-$22,000 or more. A quote that appears low may cover only the kit and assembly, rather than a ready-to-use fireplace.
Assumptions: Outdoor residential installation, standard access, ordinary soil conditions, and mid-range materials; regional pricing varies.
How Firebox, Chimney, And Labor Shape The Quote
A detailed estimate should separate the kit from installation and other job expenses. The table below shows typical U.S. planning ranges for a standard outdoor project; line items vary by package and contractor. Some estimates combine assembly, mortar, and masonry labor rather than listing them separately.
| Quote component | Typical range | Pricing basis | What changes the amount | Often excluded |
|---|---|---|---|---|
| Stone Age kit | $3,000-$8,000 | Per kit | Opening size, chimney configuration, components | Freight and finish materials |
| Masonry assembly | $2,500-$6,500 | Per project | Crew size, access, assembly complexity | Veneer and foundation |
| Foundation or slab | $500-$2,500 | Per project | Excavation, thickness, soil, reinforcement | Major retaining work |
| Veneer and finish | $1,000-$5,000 | $15-$45 per sq. ft. | Stone type, coverage, cuts, layout | Premium hand-selected stone |
| Delivery and disposal | $250-$1,200 | Per project | Distance, unloading, packaging removal | Crane or special handling |
Labor rates for masonry commonly run about $60-$110 per worker-hour, although contractors usually provide a project price. The rate does not capture every cost: mobilization, insurance, overhead, and coordination may be included in the bid. Request clarification before comparing hourly and fixed-price proposals.
Check the scope line by line before treating two estimates as comparable. One contractor may include a poured base, chimney cap, and stone veneer, while another may price only kit assembly. Ask whether delivery, mortar, flashing or weather detailing, cleanup, and final inspection are included.
Which Opening Size And Chimney Height Raise The Price
Fireplace dimensions and chimney height influence both kit selection and installation effort. A unit with a roughly 36-inch opening generally costs less than a larger 42-inch or 48-inch configuration, though available models and included parts differ. Moving up a size can add several hundred to more than $1,500 to the kit and may also increase foundation, facing, and labor costs.
Chimney height can change the material list and the amount of assembly. A typical outdoor chimney might extend about 6-10 feet above the firebox, but rooflines, nearby structures, and local requirements can affect the needed design. Added chimney sections, a finished cap, or difficult work at height may add roughly $500-$2,000 or more to the installed quote.
Site conditions are another major variable. A level, reachable patio is less expensive than a sloped yard requiring excavation, retaining work, or a longer route for materials. A new reinforced slab may cost $500-$2,500, while demolition of an existing patio or a difficult delivery that needs special equipment can add $500-$2,000. Confirm that the planned base is suitable for the kit’s weight.
Confirm the exact model, opening width, chimney height, and included components in writing. Those details make it easier to compare kit prices and identify whether a low quote assumes a smaller unit or omits structural preparation.
Three Backyard Builds Show How The Totals Add Up
These examples illustrate plausible project totals, not official Stone Age package prices. Actual bids depend on the selected model, dealer, installer, soil, finish, and local labor. Each example assumes an outdoor fireplace and excludes unrelated patio construction.
| Project | Kit | Labor and base | Finish and delivery | Estimated total |
|---|---|---|---|---|
| Compact, 36-inch opening | $3,500-$4,500 | $3,000-$4,000 | $1,000-$1,800 | $7,500-$10,300 |
| Mid-size, 42-inch opening | $4,500-$6,500 | $4,000-$6,000 | $2,000-$4,000 | $10,500-$16,500 |
| Large, tall chimney, stone veneer | $6,000-$8,000 | $6,000-$9,000 | $4,000-$7,000 | $16,000-$24,000 |
For the compact example, a level site and minimal facing keep the labor and base allowance lower. The mid-size example assumes a prepared or modestly upgraded base and a more complete stone finish. The large project allows for extra chimney work and broader veneer coverage, which can push the total beyond the usual range for a basic installation.
Per-square-foot veneer rates are useful for comparing finish quotes, but they may not include corners, openings, cuts, or minimum labor charges. Ask whether the stated rate covers material and installation. Also check whether the contractor is pricing the finished area or the fireplace’s full exterior surface.
How Many Workdays Does Kit Assembly Usually Take
A prepared site and uncomplicated kit assembly may take a two- or three-person crew about 2-4 working days. A more involved project with foundation work, custom veneer, a tall chimney, or adjacent hardscape can take 5-10 workdays, often spread across more calendar days while concrete or mortar cures. Labor costs commonly fall around $2,500-$8,500, depending on crew size and scope.
Weather and access affect the schedule as well as the bill. Rain, freezing temperatures, limited staging space, stairs, and long material-carrying distances can slow masonry work. Ask how many labor days the estimate assumes and whether site delays or return visits are billed separately. A clear schedule helps explain why installation quotes can differ even when the kit is identical.
Delivery should be coordinated with a suitable unloading location and a prepared base. A standard local delivery may cost about $250-$700; longer distances or special handling can raise it to $1,200 or more. Confirm whether the truck can reach the work area, whether unloading is included, and who is responsible for moving heavy components from the drop point.
How Regional Labor And Freight Change The Installed Price
Location changes the price even when the same kit is selected. In lower-cost rural or Midwestern markets, a routine installation may fall near the lower half of the national planning range. High-cost coastal metros and areas with limited masonry crews may run roughly 15%-35% higher for labor and related project charges. These are broad comparisons, not a city-by-city price guarantee.
Freight is especially relevant if the nearest dealer or distribution point is far from the property. A short regional delivery may be a few hundred dollars, while long-distance transport, limited truck access, or special unloading can add several hundred dollars more. Ask the seller for a delivered kit price rather than comparing product-only quotes from different sources.
Local rules can add design or inspection expenses. Permit needs vary by municipality and by whether the fireplace is near a structure, property line, or combustible materials. Allow roughly $100-$800 for routine permits and inspections where required, with additional costs possible for drawings or site-specific review. The installer should identify who checks local requirements and whether fees are included.
Compare installed quotes from contractors who serve the same area and define the same scope. A regional percentage is useful for budgeting, but it cannot replace a local estimate that accounts for access, delivery, and required approvals.
Kit-Only Pricing Versus A Finished Masonry Fireplace
Buying the kit separately can make the product price easier to evaluate, but it does not automatically reduce the finished-project cost. The buyer may need to coordinate delivery, confirm component compatibility, and arrange a qualified installer. If the contractor cannot verify the package or has to correct missing items, the apparent savings can disappear through delays and additional labor.
A turnkey quote typically combines the kit, assembly, base, delivery, and agreed finish work. It can be easier to compare, but the quote should still itemize allowances and exclusions. Some packages are priced before veneer or patio work; others include a limited finish material allowance that can be exceeded by choosing a more expensive stone.
Stone veneer, brick, stucco, or a simpler exposed masonry finish can create very different budgets. A basic finish may add around $1,000-$2,500, while extensive natural-stone facing can add $3,000-$5,000 or more, depending on coverage and material selection. Confirm the visible finish in the written scope, including hearth edges, chimney sides, and the area around the opening.
Repairing an existing outdoor fireplace may be cheaper if the firebox and chimney remain sound, but it is not a direct substitute for a new kit when the structure is damaged or poorly sized. A masonry inspection or repair visit may cost $150-$500, with repair work often running $500-$3,000 for limited repointing or component replacement. Extensive structural problems can make rebuilding more practical.
Which Finish And Site Decisions Can Lower The Quote
Choose the smallest opening and chimney configuration that meets the intended layout and local requirements. Avoid paying for extra height, upgraded caps, or decorative trim unless the project needs them. A change in kit size may save several hundred to more than $1,500, with additional savings possible in labor and finish materials. Verify the final model before ordering because changes after delivery can create restocking or return charges.
Control veneer coverage by selecting a defined finish area and a material with predictable supply. Using stone only on the front rather than wrapping every side may reduce material and installation charges by several hundred to a few thousand dollars. Keep the visible result consistent by specifying exposed sides, corners, hearth treatment, and chimney finish instead of relying on an informal allowance.
Prepare access and the work zone before the crew arrives. Clearing a path, moving patio furniture, confirming delivery access, and resolving minor site obstructions can help avoid extra labor or return-trip charges. Do not undertake excavation or base construction without the installer’s approval; an unsuitable base can create safety issues and costly correction work.
Obtain at least three written bids with the same kit model, opening size, chimney height, finish area, delivery terms, and foundation assumptions. Ask each contractor to list exclusions and change-order rates. The most useful savings usually come from trimming unnecessary scope, not choosing an installer solely by the lowest headline price.
