Should I just pick the lowest number?

Only if the scopes truly match. A lower total often reflects a narrower job, such as no insulation replacement, no moisture correction or no rebuild. Fill in the worksheet first, then compare totals for the same work.

How many estimates are enough?

Two or three is typical for a planned job. More than that tends to add confusion rather than clarity, especially if each contractor proposes a different approach to the same crawlspace or basement.

What if two contractors disagree about the cause?

That is worth resolving before signing anything. Ask each to explain the evidence for their view, such as moisture readings, staining patterns or a plumbing test. An independent assessor can help if the disagreement persists, because the wrong diagnosis means the mold returns.

Comparing Two Mold Removal Estimates Line by Line

Side-by-side worksheet

Copy this table and fill in a column for each proposal. Leave a cell blank if the proposal does not say; that blank is a question to ask.
Line item	Proposal A	Proposal B	Proposal C
Moisture source identified
Areas included, with measurements
Containment type and size
Negative air and exhaust point
Materials removed
Cleaning method for framing
Insulation removal and replacement
Drying and target readings
Coatings or antimicrobials
Asbestos testing addressed
Completion check or verification
Rebuild included or excluded
Moisture correction included or excluded
Records provided at the end

Signals in a proposal

Encouraging

Names the moisture source and how it was confirmed
Specifies containment and air filtration
Describes what is removed versus cleaned
Explains how completion will be judged

Worth questioning

One lump line with no breakdown
Relies mainly on fogging or spraying
No mention of what caused the water
Vague language like treat affected areas

Making the comparison fair

Before comparing totals, make sure each proposal covers the same area and the same work. If one includes rebuilding drywall and another stops at removal, they are not competing for the same job. Ask each contractor to price the same scope, or to list what is left out.

It also helps to send every contractor the same photos and the same description, and to be home for each walkthrough. A contractor who spends time measuring and looking at the water source is gathering what an accurate scope needs.

Before you sign

The scope is written and matches what was discussed
Exclusions are listed
The plan for unexpected findings is described
Start date and expected duration are stated
Payment schedule is tied to stages of work
You know who to contact during the job
