A gravel pad for a mobile home typically costs $3,000-$10,000 installed, with many straightforward projects landing near $5,500. Pad dimensions, excavation and drainage needs, gravel depth, soil conditions, and local equipment and labor rates drive the final quote.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Installed gravel pad | $3,000 | $5,500 | $10,000 | Common single-wide pad and normal access |
| Installed price per square foot | $3 | $5 | $8 | Includes typical grading, stone, and compaction |
| DIY materials and delivery | $1,500 | $2,800 | $5,000 | Excludes rented equipment and owner labor |
| Large or difficult site | $8,000 | $12,000 | $20,000 | May need deeper excavation, drainage, or retaining work |
Assumptions: U.S. prices for a compacted crushed-stone pad, ordinary access, and no major retaining wall or utility relocation.
What a Typical Mobile Home Gravel Pad Costs
For a single-wide home, a contractor-installed pad often costs $3,000-$7,000. A double-wide pad commonly runs $5,000-$12,000 because it covers more area and may require additional grading, stone, and machine time. Difficult slopes, weak soil, long delivery distances, or substantial drainage work can push a project above $15,000.
A useful planning rate is $3-$8 per square foot for a prepared, installed gravel surface. The low end usually reflects a level, accessible site with shallow preparation and locally available aggregate. The high end can reflect excavation, fabric, thicker stone, drainage improvements, and labor in a higher-cost market. Quotes may use a pad footprint, a gravel quantity, or a combined project price, so the estimate should state the dimensions and included work.
For a typical single-wide site with routine preparation, budgeting about $4,000-$7,000 is a reasonable starting point. The home’s length and width are not always the pad’s finished dimensions: installers may need extra working room around the home, and the plan must account for support locations, access, and local installation requirements.
A 16-by-72-foot pad covers 1,152 square feet. At $3-$8 per square foot, that area suggests $3,456-$9,216 before any unusual site work. The actual quote can differ if a contractor prices minimum equipment mobilization, delivery, or grading separately rather than applying a simple square-foot rate.
How Excavation, Stone, and Labor Shape the Quote
Contractor estimates may bundle several tasks. Asking for line items helps show whether a low bid leaves out essential base preparation or a high bid includes drainage and disposal that another quote excludes.
| Cost component | Typical price | What changes the amount | Common unit |
|---|---|---|---|
| Clearing and excavation | $400-$2,000 | Vegetation, roots, cut depth, and soil removal | $1-$4 per sq ft |
| Geotextile fabric | $150-$700 | Fabric weight, overlaps, and pad area | $0.15-$0.60 per sq ft |
| Crushed stone and delivery | $800-$3,500 | Depth, stone type, haul distance, and load size | $30-$75 per ton delivered |
| Spreading and compaction | $700-$2,500 | Machine access, number of lifts, and crew time | $50-$125 per labor hour |
| Drainage and finish grading | $300-$2,500 | Swales, pipe, slope, and outlet location | $3-$12 per linear ft for basic drainage |
These ranges describe common line items, not guaranteed separate charges. A small job may have a minimum mobilization fee, while a larger contractor quote may combine equipment and labor into one price. Stone is often the largest material expense, but excavation and hauling can dominate where unsuitable soil must be removed.
Labor is often priced through crew time, equipment use, or a fixed bid rather than a simple hourly invoice. A basic site may need a few workers for one day; a site involving cut-and-fill work or drainage can take longer and require several machines.
Pad Width, Gravel Depth, and Soil Change the Price
Area is one of the clearest cost drivers. A compact 14-by-60-foot footprint is 840 square feet, while a 16-by-76-foot pad is 1,216 square feet. At an installed rate of $3-$8 per square foot, those examples indicate roughly $2,520-$6,720 and $3,648-$9,728, respectively, before special site conditions.
Gravel depth also changes the material quantity. A compacted layer around 4-6 inches may work for some well-drained, firm sites, while weak soil, heavier traffic, or local engineering requirements may call for 8-12 inches or a layered base. More depth means more tons to buy, move, and compact; it can also require additional excavation so the finished pad does not sit too high.
Adding 2 inches of stone across 1,000 square feet requires roughly 12-13 cubic yards of loose aggregate, depending on compaction and stone density. Suppliers usually sell by the ton, so the contractor should document the assumed depth and conversion used to calculate the order. A quote that states only “one load” is difficult to compare without the load size.
Soil and slope can shift the estimate substantially. Firm, level ground may need only limited stripping and grading. Soft clay, organic topsoil, a slope above about 5%, standing water, or a low area requiring fill may call for deeper excavation, geotextile, engineered drainage, or a retaining solution. These conditions can add $1,000-$6,000 or more depending on the amount of earthwork.
Pad boundaries should be defined before bidding. A narrow pad can save stone, but it may not provide enough access for installation and future maintenance. The contractor should confirm dimensions, support layout, finished elevation, runoff direction, and any requirements from the home installer or local authority.
How Long Grading and Compaction Usually Take
A straightforward pad on a cleared, accessible site may take one to two working days after delivery is scheduled. That can include light excavation, fabric placement, stone spreading, compaction, and finish grading. Larger double-wide sites, long drive-in routes, or multi-layer bases can take two to four days, excluding weather delays and permit review.
Equipment and labor charges vary by market, but a compact excavator or skid steer may add about $300-$900 per day, with operator and delivery sometimes priced separately. Labor rates commonly fall around $50-$125 per hour per worker, though contractors may quote a crew rate or a fixed project total. A small project can still carry a meaningful mobilization charge because hauling machinery and arranging aggregate delivery cost money regardless of pad size.
Confirm whether the quoted schedule includes equipment delivery, stone hauling, and final compaction. Separate visits can raise charges, and a wet site may need to dry before heavy equipment can work without rutting the ground. Home placement should be coordinated with the installer so the pad is accessible and ready when the delivery or setup crew arrives.
Rain, frozen ground, and peak construction periods can affect scheduling more than the stated labor rate. Weather is especially important where drainage work or soil stabilization is required. A contractor may need to reschedule aggregate delivery if trucks cannot reach the site safely, and a rushed date can incur an additional charge if it requires overtime or special delivery arrangements.
Why Rural and Urban Gravel Pad Quotes Differ
Local labor and delivery distance make national averages imperfect. In rural areas, nearby aggregate may be inexpensive, but a contractor could charge more for hauling machinery or traveling to a remote property. Urban and suburban projects may have higher labor rates, restricted truck access, traffic delays, disposal fees, or limited room to stockpile stone.
As a broad budgeting adjustment, quotes in high-cost metro areas may run 15%-30% above a comparable project in a lower-cost region. Remote sites can be 10%-25% higher when long hauls or limited contractor availability apply. These percentages are planning estimates, not fixed regional price lists; a nearby quarry or a difficult access road can reverse the comparison.
For a $5,500 baseline, a 20% regional premium would put a comparable bid near $6,600. The cleanest comparison is to ask each contractor to list delivered stone quantity, haul distance assumptions, labor, equipment, and site preparation. Local per-ton rates can differ markedly, and aggregate delivery may include a minimum load or a distance surcharge.
Call more than one local contractor and, where practical, ask the aggregate supplier for delivery pricing separately. That does not mean buying materials independently will be cheaper: a contractor may obtain trade rates, and the homeowner takes on quantity, timing, and unloading coordination. A separate supplier quote is most useful as a check on the estimate’s material and delivery assumptions.
Drainage, Clearing, and Delivery Add-Ons to Budget
Clearing brush, removing a small tree, or stripping topsoil may add $300-$2,000. Hauling away unsuitable soil often costs about $15-$50 per cubic yard, plus truck or disposal minimums. If excavated material can be spread elsewhere on the property, disposal costs may be lower, but only if the site plan allows it and the material is suitable.
Drainage work can add $300-$2,500 for basic swales, shaping, or short runs of pipe. Longer drain runs, a catch basin, difficult outlets, or a retaining wall can bring the added expense to $3,000-$10,000 or more. The goal is to keep water from collecting beneath or alongside the pad and to direct runoff in a permitted, practical direction rather than toward neighboring property.
Ask whether the price includes fabric, compaction, water management, and removal of excess soil before accepting a total bid. Fabric may be especially useful where soils are soft or fine-grained because it can separate the native soil from the stone. It does not replace proper drainage or make an inadequately prepared base suitable.
Other possible charges include utility locating, access-road repairs, permit fees, and delivery surcharges. A permit or inspection may be required by local rules, zoning, or the home’s installation plan; costs vary by jurisdiction and scope. The contractor should clarify which approvals are included and whether the owner must arrange them. Utility lines should be located before excavation, since damage can create a far larger bill than routine preparation.
Gravel Versus Concrete or a Thinner Stone Base
Gravel is often less expensive than a poured concrete pad, but the surfaces serve different purposes and local installation requirements matter. A basic concrete slab can cost roughly $8-$15 per square foot, or about $9,000-$17,000 for 1,100 square feet, before challenging access or reinforcement. Concrete requires suitable design and curing; it should not be assumed interchangeable with the support system specified for a manufactured home.
A thinner gravel layer may reduce the initial invoice, but cutting depth without checking soil strength, drainage, and installation requirements can lead to rutting or settlement. Replenishing stone and regrading may cost $300-$1,500 per service visit, depending on area and access. The least expensive acceptable base is not necessarily the thinnest one.
Compare the required home-support design first, then compare surface materials and maintenance costs. Some homes are supported by piers or other systems over a prepared site rather than resting directly on a continuous gravel surface. The pad’s function, bearing conditions, and tie-down or foundation requirements should be confirmed with the installer and local code officials.
Gravel may need occasional topping up where vehicles, water flow, or settlement displace stone. A concrete alternative can reduce loose-stone upkeep but costs more initially and may require specialized engineering or site preparation. Quotes should identify the intended finish and support arrangement so that a lower price is not simply based on a different scope.
Three Example Quotes for Common Pad Sizes
Examples show how scope changes the total. They assume ordinary regional pricing and exclude home transport, utility connections, and foundation or anchoring costs unless stated. Actual bids depend on local stone prices, site access, and installation specifications.
| Scenario | Scope and material | Labor and equipment | Estimated total |
|---|---|---|---|
| Small single-wide | 14 by 60 ft, 840 sq ft; 4-6 in. crushed stone | 12-16 crew hours; light grading and compaction | $3,000-$5,500 |
| Typical single-wide | 16 by 72 ft, 1,152 sq ft; fabric and 6 in. base | 18-26 crew hours; excavation and delivery | $4,500-$8,500 |
| Double-wide on sloped ground | 28 by 76 ft, 2,128 sq ft; 8-10 in. base and drainage | 30-45 crew hours; cut-and-fill and compaction | $10,000-$20,000 |
Assumptions: The listed labor hours are combined crew hours, not elapsed project duration; local rates and material quantities vary.
The small example assumes a cleared site and no major soil replacement. The typical example includes fabric and a thicker, compacted base, making it more representative of a contractor-prepared installation area than a simple gravel drop. The double-wide estimate includes the cost impact of slope-related work, but a retaining wall or unusually poor soil could exceed the high end.
Use the dimensions and listed work to compare quotes, not the total alone. A bid of $4,000 that excludes excavation and compaction may not be cheaper than a $6,000 bid that includes them. Request written quantities for stone and excavation, specified depth, fabric, drainage, disposal, and any final grading.
Lower the Gravel Pad Price Without Cutting Needed Support
Accurate dimensions are the first cost control. Have the home installer confirm the required work area and support layout before ordering material; an oversized pad can add hundreds or thousands of dollars in stone and grading. Avoid shrinking it below the required footprint just to reduce the bid, since limited room can complicate setup and maintenance.
Clearing small vegetation, moving loose debris, and providing a clear equipment route may reduce crew time if the contractor agrees that owner preparation is safe and useful. Do not remove soil or alter drainage without confirming the finished elevation and site plan. Rework caused by incorrect grading can cost more than the initial labor saved.
Compare at least three written bids with matching dimensions, depth, and included tasks. Ask whether a nearby delivery day, flexible scheduling, or combining the pad with other grading on the property can reduce mobilization charges. Confirm that a lower-priced material is still appropriate for the soil and intended base, rather than substituting ungraded fill or unsuitable stone.
Request separate prices for optional drainage upgrades, extra stone, or soil export. This makes it easier to distinguish necessary work from contingencies that may not apply. If the site is already level, firm, and well-drained, ask the contractor to document why extensive excavation is needed. If it is wet or unstable, prioritize a sound base and water management over cosmetic savings.
Finally, check the quote’s payment schedule, change-order terms, delivery quantity, and responsibility for permits or utility locating. A complete bid should state the pad size, compacted depth, aggregate type, fabric allowance, grading direction, and disposal plan. Clear scope is the most reliable way to keep a gravel pad within budget without compromising the home’s installation requirements.
