Start with the boundaries of the job

Ask each contractor to identify the affected rooms, materials and planned removal limits. If an independent assessment exists, provide the same plan to every bidder. An estimate based on a couple of photographs may be preliminary. Hidden conditions need a written change process, not a vague promise that the price will stay the same regardless of what is found.

Building logistics can change the effort

A ground-floor room with direct outside access is different from an occupied apartment reached through a shared elevator. Ask about protection of common areas, approved work hours, elevator reservations and debris movement. These are project-planning questions, not a reason to accept an unexplained “NYC surcharge.” A good proposal states what the access assumptions are.

Separate the professional roles and trades

Assessment and post-remediation review may be separate contracts. Plumbing, roof repairs, electrical work and reconstruction may also sit outside the remediation price. Ask who schedules them and what must happen before the remediation starts or the area closes. An apparent price gap may simply mean one contractor included work another excluded.

Understand equipment and documentation

If drying or filtration equipment is included, ask how duration is determined, how extensions are authorized and whether monitoring is included. Ask what closeout documents you receive. Do not buy a fixed machine count as a substitute for an appropriate plan. Equipment should be matched to the actual conditions and work requirements.

Ask about changes before signing

The proposal should explain payment timing, exclusions, disposal, access requirements and how additional work is approved. Avoid treating a generic online price-per-square-foot range as a quote for your building. Send the location, affected materials, water history and existing assessment to obtain a project-specific scope. Insurance reimbursement is a separate decision made under the policy; a contractor cannot guarantee coverage.

Your next-step checklist

  • Give bidders the same assessment and access information.
  • Identify assessment, repairs and rebuilding exclusions.
  • Confirm equipment duration and extension terms.
  • Require written approval for scope and price changes.
