Estimates are planning tools
Onceo calculators and planners provide estimates based on the measurements, prices, selections, and other information you enter.
Results are intended to help with early project planning. They are not guaranteed measurements, purchase quantities, installation specifications, bids, or professional recommendations.
Verify material requirements
Actual material requirements may differ from Onceo estimates because of waste, cuts, spills, settling, compaction, coverage rates, product dimensions, application methods, surface conditions, packaging, and manufacturer specifications.
Verify quantities and product coverage with the manufacturer, retailer, supplier, installer, or other appropriate source before purchasing materials.
Costs can vary
Cost calculations depend on prices entered into the planner and do not guarantee actual purchase or project costs.
Taxes, delivery fees, equipment rental, labor, disposal, minimum order quantities, regional pricing, and other expenses may not be included unless specifically shown.
Project and site conditions
Every property and project is different. Soil conditions, drainage, existing structures, substrate conditions, weather, access, slopes, utilities, and other site factors may affect how a project should be designed or completed.
Codes, permits, and professionals
Onceo does not determine whether your project requires a permit, inspection, engineering review, utility location, or licensed professional.
Always follow applicable laws, codes, manufacturer instructions, safety requirements, and professional guidance. Use qualified professionals when a project requires expertise beyond your knowledge or experience.
Safety
Home improvement work can involve tools, heavy materials, excavation, electricity, structures, chemicals, and other hazards. Follow appropriate safety instructions and do not rely on Onceo as a substitute for safety training or professional judgment.
Final responsibility
You are responsible for reviewing and verifying your project plan before purchasing materials or beginning work. When in doubt, consult an appropriate supplier, contractor, engineer, inspector, or other qualified professional.
