How to Price Your Jobs When Material Costs Keep Changing
Material price volatility has become a persistent challenge for US contractors. Lumber, copper, PVC, concrete — the prices you quoted materials at last month may not be what you pay this month. This guide covers practical strategies for protecting your margins when input costs are moving.
Never Quote Materials at a Fixed Price for Long Projects
For projects longer than two to three weeks, include a material price validity clause in your quote. Something as simple as “materials pricing valid for 14 days from quote date — subject to supplier price increases on acceptance after this date” protects you from absorbing significant cost increases on work you have not yet started.
Build a Buffer Into Every Quote
Add a minimum 10–15% contingency on materials costs in every quote. This is not padding — it is protection against the realistic range of price movement between quoting and purchasing. When prices are particularly volatile, increase this to 20%.
Use Real-Time Supplier Pricing
Check your actual supplier pricing when building each quote, not a price you remember from last month. This takes longer but prevents the margin erosion that comes from quoting on stale price memory. A saved rate library in a quoting app should store your labour rates (which change rarely), not materials prices (which change often).

Pass Through Significant Cost Increases Transparently
If material costs rise substantially between quoting and starting work on a longer project, communicate this to the client promptly and in writing. Most clients understand market conditions when explained clearly. A transparent conversation about a 15% lumber cost increase is far better than absorbing it silently and losing the margin on the job.

The Associated General Contractors of America publishes guidance on materials escalation clauses for US contracts.
Only if your quote includes a price validity clause or a materials escalation clause. Without one, you may be contractually bound to the quoted price. Always include validity periods on quotes — the FTC’s home improvement guidance covers contractor contract requirements.
