Money-Saving Tips
Professional estimates cost $500-$5,000 but save 10-20% by catching scope gaps before construction starts.
Free contractor estimates are valuable but biased — independent QS gives you leverage in negotiations.
Itemized estimates expose markup — compare line by line, not just bottom-line totals.
For projects over $100K, a QS estimate pays for itself by identifying $10K-$30K in scope gaps.
Keep your estimate as a baseline — compare actual costs against it to catch budget creep early.

Estimating Cost FAQs
How accurate is a renovation estimate?
Depends on the type. A rough order of magnitude (ROM) using $/sq ft averages is ±30-50% accurate — enough to know if your kitchen is a $40K or $80K project. A preliminary estimate with approximate quantities gets you to ±15-25%. A detailed estimate with full material takeoffs and firm subcontractor quotes should be ±5-10%. The estimate becomes a budget, and actual costs depend on how well you control scope changes.
What's a contingency and how much should I budget?
Contingency is money set aside for unknowns — things you discover when you open walls or dig footings. Use 10% for new construction or well-defined scope, 15-20% for renovations in homes built before 1980, and 25%+ for heritage homes or projects with structural uncertainties. Every renovation uncovers something. Homeowners who skip contingency end up scrambling for money mid-project or making bad compromises on quality.
Why are quotes from three contractors so different?
Usually different scopes. One contractor includes asbestos abatement and structural engineering, another assumes you handle permits, a third forgot to price the new HVAC ductwork. Get all three to itemize their quotes by trade, then compare line by line. A 10-15% difference is normal (overhead and profit vary), but 30%+ means someone is missing scope or padding the estimate.
Should I always get three quotes?
Not always. Get three quotes if you have clear drawings and specifications — it helps you understand market pricing and contractor reliability. Skip the three-quote dance if your project is custom or design-build, because you're not comparing apples to apples. One good contractor with a detailed estimate and solid references is better than three half-assed quotes.
What's a material takeoff?
A material takeoff is the process of counting and measuring every material needed for construction. For framing: count studs, plates, headers, sheathing sheets. For drywall: calculate wall and ceiling area, convert to sheets, add 10% waste. For trim: measure linear feet of baseboard, casing, crown. Takeoffs turn architectural drawings into shopping lists. Accurate takeoffs prevent mid-project material shortages and reduce waste.
