Sump Pump Installation Proposal Template: Win Basement Water-Control Jobs Without Eating Drainage, Electrical, and Discharge Scope

Sump pump jobs look small until the first heavy rain proves what the estimate forgot.

The homeowner sees a pump. You see pit size, liner condition, inlet pipes, check valve, discharge route, exterior grading, freeze risk, power availability, GFCI rules, battery backup, alarm, permit requirements, concrete cutting, dust control, and whether the real problem is drainage, not the pump.

That is why sump pump proposals need tight boundaries.

If your estimate says "install sump pump - $2,800," the client may assume it includes a new basin, concrete work, electrical, battery backup, exterior discharge, drain tile tie-in, floor cleanup, and future water protection. A better proposal names exactly what is included and what is not.

Use this template for sump pump replacement, new sump pump installation, battery backup upgrades, basement waterproofing support, drain tile tie-ins, high-water alarms, and emergency water-control projects.

Why Sump Pump Proposals Lose Money

1. Replacement and new installation get confused. Replacing a pump in an existing pit is not the same as cutting concrete, installing a basin, connecting drain tile, and routing discharge.

2. Discharge routing is underpriced. Exterior routing, freeze protection, grading, daylight discharge, dry wells, and municipal rules can change the job.

3. Electrical is assumed. Pumps and backup systems need proper power. If outlets, GFCI protection, dedicated circuits, or panel work are required, the proposal should say whether that is included.

4. Battery backup is treated as an afterthought. Homeowners often need a good/better/best choice: pump only, pump plus backup, or full protection with alarm and discharge improvements.

5. Drainage problems are not excluded. A pump cannot fix bad gutters, grading, foundation cracks, hydrostatic pressure, blocked drain tile, or sewer backup by itself.

6. Emergency expectations are vague. If the basement is wet now, cleanup, drying, damage repair, and contents handling are separate scopes.

What Every Sump Pump Proposal Needs

A professional sump pump installation proposal should answer:

• Is this a replacement or new installation?
• Is an existing pit being reused?
• Is concrete cutting included?
• What pump horsepower and type are included?
• Is a check valve included?
• Where does the discharge line run?
• Is battery backup included?
• Is electrical work included or excluded?
• Are drain tile, waterproofing, cleanup, and restoration excluded?
• What warranty applies to labor and equipment?

Include these sections:

• Project summary with water issue, existing conditions, and recommended option
• Existing condition notes for pit, pump, discharge, outlet, floor, and exterior route
• Scope of work broken into removal, basin/pit, pump, piping, discharge, backup, testing, and cleanup
• 3-tier pricing for pump replacement, backup protection, and full water-control upgrade
• Itemized estimate with allowances and optional upgrades
• Assumptions and exclusions for drain tile, electrical, foundation repair, exterior grading, and water damage
• Payment terms with deposit, completion payment, and change-order rules

The proposal should sell water-control clarity, not a magic promise that the basement will never see water again.

SUMP PUMP INSTALLATION PROPOSAL
Prepared by: DryLine Basement Systems
License: Waterproofing Contractor WC-38290
Insurance: General Liability $2,000,000 per occurrence | Workers' Comp: Active
Date: May 10, 2026
Proposal valid for: 14 days

Client: Jordan Ellis
Property: 603 Pine Hollow Court, Columbus, OH 43214
Email: jordan@example.com
Phone: (614) 555-0162

Project Summary

Replace existing failed sump pump and improve basement water-control reliability. Scope includes removal of existing pump, inspection of existing basin, installation of new 1/2 HP cast-iron sump pump, new check valve, discharge piping connection to existing route, battery backup option, high-water alarm option, functional test, cleanup, and client walkthrough.

Recommended option is Pump + Backup Protection because the basement has finished areas and the existing pump failure created water intrusion during a storm.

Existing Conditions

Area	Condition Observed	Proposal Handling
Existing pump	Failed pedestal pump in existing pit	Remove and replace with submersible pump
Basin	Existing basin appears usable	Basin replacement excluded unless damaged
Discharge	Existing discharge route present	Reconnect to existing route; rerouting optional
Power	Outlet near pump present	Electrical upgrades excluded unless selected
Basement	Finished walls near mechanical area	Water damage repair excluded
Exterior	Discharge outlet visible	Freeze-proofing or extension optional

Condition limit: This proposal is based on visible conditions only. Blocked drain tile, damaged basin, failed discharge line, electrical deficiencies, foundation leaks, sewer backup, exterior drainage problems, or water-damaged finishes require written change order approval.

Scope of Work

Phase	Included Work
Site setup	Protect immediate work area and confirm access
Removal	Disconnect and remove existing failed pump
Basin check	Inspect visible basin condition and inlet flow where accessible
Pump install	Install new 1/2 HP cast-iron submersible sump pump
Check valve	Install new check valve and reconnect to existing discharge piping
Backup option	Install battery backup system if selected
Alarm option	Install high-water alarm if selected
Testing	Fill/test basin, verify pump operation, check valve function, and discharge flow
Cleanup	Remove old pump and work debris; walkthrough with homeowner

3-Tier Pricing

Tier	Best For	Included Scope	Example Price
Pump Replacement	Existing pit and discharge route are usable	Remove old pump, install new primary pump, check valve, reconnection, test, cleanup	$1,950
Pump + Backup Protection	Finished basements or storm-risk homes	Replacement scope plus battery backup pump, battery box, charger, high-water alarm, owner walkthrough	$4,850
Full Water-Control Upgrade	Homes needing stronger reliability and discharge improvements	Backup package plus basin replacement allowance, discharge reroute allowance, exterior extension, monitoring alarm, expanded testing	$8,900

Recommended option: Pump + Backup Protection. It protects the basement when the primary pump fails or power drops during a storm.

Follow-Up Email Template

Subject: Sump pump proposal and backup option for 603 Pine Hollow Court

Hi Jordan,

I attached the sump pump proposal with three options: primary pump replacement, pump plus battery backup protection, and a full water-control upgrade.

The recommended option includes a new cast-iron primary pump, check valve, battery backup pump, alarm, testing, cleanup, and walkthrough. It uses the existing basin and discharge route unless we find damage or blockage during installation.

The proposal excludes drain tile work, electrical upgrades, foundation leaks, exterior drainage correction, water damage restoration, and sewer backup protection unless separately approved.

If you approve the recommended option, we can reserve the next installation window.

Thanks,
DryLine Basement Systems

FAQ

Should every sump pump proposal include battery backup?

Not always, but it should usually be offered. Finished basements, storm-prone homes, and older pumps benefit from backup protection.

Is electrical work included in sump pump installation?

Only if the proposal says so. Many sump jobs assume an existing safe outlet. Dedicated circuits, GFCI changes, and panel work should be separate.

Does a sump pump fix basement waterproofing problems?

No. A sump pump manages collected water. It does not fix foundation cracks, poor grading, blocked drains, gutter problems, or sewer backups by itself.

How do contractors avoid sump pump scope creep?

Separate pump replacement from basin work, drain tile, discharge rerouting, electrical, cleanup, restoration, and exterior drainage. Put those boundaries in the proposal.
