Quick, low-risk steps

  1. Stay out of water near electricity and record where water appears.
  2. Collect at least three written quotes with line-item scope details.
  3. Enter each quote into the comparer columns: source, method, drainage, pump, discharge, restoration, warranty.
  4. Ask every bidder to state the proposed water source and evidence.
  5. Compare drainage, discharge, demolition, restoration, and warranty across quotes.
  6. Do not rely on this tool alone; have a waterproofing professional review your comparison.

How to Use the Scope Comparer

The comparer is a private on-page worksheet. You fill in details from each written quote. No data is saved or shared. It helps you see what each contractor includes and what they leave out.

Start by listing the contractor name and date. Then enter the proposed water source, waterproofing method, and whether work is interior or exterior. Note linear feet and access conditions.

  • Enter each quote in a separate column.
  • Record the proposed water source and evidence.
  • Note interior or exterior method and linear feet.
  • Include demolition and material handling details.
  • List drainage components and sump pump specs.

Key Scope Items to Compare

A complete quote should address drainage, sump pump, discharge, permits, and restoration. Missing items can lead to surprise costs later. Use the checklist to ask about each item.

Compare the type and capacity of the sump pump, backup system, and where water will discharge. Discharge must direct water away from the foundation without creating new problems.

  • Drainage: interior drain tile, exterior French drain, or other.
  • Sump pump: primary pump type, backup battery or water-powered.
  • Discharge route: where does the water go?
  • Permits and electrical work: who handles them?
  • Finish restoration: who repairs drywall, flooring, etc.?

Warranty and Maintenance Comparison

Warranties vary widely. Some cover materials only, others include labor. Check what is excluded, such as pre-existing cracks or hydrostatic pressure. A long warranty is only as good as the company behind it.

Ask about maintenance requirements. Some systems need annual inspections. Others require you to keep discharge lines clear. Compare what each contractor expects you to do after installation.

  • Warranty length and what it covers.
  • Exclusions: pre-existing conditions, acts of nature.
  • Transferability if you sell the home.
  • Maintenance obligations for the homeowner.
  • Who to call for service and response time.

Limitations of This Tool

This comparer does not evaluate contractor quality, verify licenses, or check references. It only helps you organize quote details. You must still research each company and read reviews.

The tool cannot tell you which method is right for your basement. Only an on-site inspection by a qualified professional can determine the best approach. Use this worksheet to have informed conversations.

  • Does not rate or rank contractors.
  • Cannot diagnose your water problem.
  • No data is saved or shared.
  • Always verify licenses and insurance separately.
  • Professional review is required before publication.

Common questions

What homeowners ask next

Can this tool tell me which quote is best?

No. It helps you compare scope items side by side, but you must evaluate contractor reputation, experience, and your specific situation separately.

What if a quote is missing key items?

Ask the contractor to provide missing details in writing. If they cannot, consider it a red flag and compare with other quotes that are more complete.

Do I need a professional to review my comparison?

Yes. A waterproofing professional or structural engineer can help you understand the differences and which approach is appropriate for your home.
