Stamped Concrete Patio

This proposal covers a decorative stamped concrete patio at {{client_address}} — {{patio_sqft}} sq ft with {{stamp_pattern}}.

Prep

• Excavate to 8"–10" below finished grade

• Install 4" compacted aggregate base

• Set forms, verify slope for drainage

• Install 6x6 wire mesh on chairs

• Plumbing and electrical sleeves if needed for future furniture (itemized if requested)

Pour

• Concrete mix: 4,000 PSI with integral color (base color mixed into concrete)

• Pour slab to 4" thickness

• Screed and bull-float

• Apply color release (accent color) before stamping

• Stamp pattern at proper window (concrete must be plastic but not too wet)

• Detail edges, stamp seams, and borders

Curing

• Cure under plastic sheeting for 48 hours

• Remove forms

• Saw control joints within 24 hours of pour (1/4 slab thickness)

• Allow 7 days for minimum cure before sealer

Sealer

• Pressure-wash patio clean (remove excess color release per manufacturer)

• Apply two coats {{sealer_type}} at manufacturer rate

• 24-hour dry between coats; 72 hours before foot traffic

Care guide

• Reseal every 2–3 years with acrylic sealer

• Avoid deicing salts in winter climates (damages surface)

• Clean with mild detergent; avoid acid-based cleaners

Estimated duration: 5–7 working days plus cure time.

• **Day 1:** Prep and form

• **Day 2:** Pour and stamp

• **Day 3:** Saw joints, remove forms

• **Days 4–10:** Cure

• **Day 11:** Seal (pressure wash + two coats)

• **Day 12:** Walkthrough

Start date: {{start_date}}. Stamping requires narrow weather window; no pour if rain is forecast within 12 hours or temps below 50°F.

Total contract price: {{total}}

• **Deposit: {{deposit}}** — signing

• **Balance: remainder** — at sealer application and walkthrough

Balance due at sealer application.

Invoices are due upon receipt. Payments more than ten (10) calendar days past due accrue a service charge of one and one-half percent (1.5%) per month on the unpaid balance, or the maximum rate permitted by law, whichever is less. {{contractor_name}} reserves the right to stop work and preserve lien rights if any progress payment is not received within five (5) business days of the due date. All retained mechanic's lien, stop notice, and bond rights under applicable state law are preserved.

The following items are specifically NOT included in the contract price and are the responsibility of {{client_name}} unless added by written Change Order:

• Permits, plan-review fees, and jurisdictional inspection fees unless explicitly itemized above

• Repair or remediation of pre-existing code violations discovered during the work

• Asbestos, lead paint, mold, or other hazardous material abatement

• Structural engineering, architectural drawings, or third-party design services

• Finish selections, fixtures, or appliances not listed in the itemized scope

• Work on concealed systems (electrical, plumbing, HVAC, framing) beyond the points of connection identified

• Landscaping restoration beyond returning disturbed areas to rough grade

• Post-completion cleaning beyond construction broom-clean

• Demo of existing patio (if applicable; priced per sq ft)

• Outdoor lighting, electrical, or water features

• Retaining walls

• Drainage systems beyond slope (French drains priced separately)

• Re-sealing after Year 2 (provided at discount for contract customers)

This proposal is based on the following assumptions. If any assumption is incorrect, the contract price and schedule are subject to adjustment by Change Order:

• Site access is available during normal working hours (7am–5pm, Monday–Saturday)

• Adequate parking is available within 100 feet of the work area

• Electrical power and potable water are available on-site at no cost to contractor

• Existing structural elements, waste lines, water supply, and electrical service are in serviceable condition unless noted

• {{client_name}} will remove personal property, artwork, and valuables from the work area prior to start

• Work is based on a single mobilization; re-mobilization required due to delays outside contractor's control will be billed at current rates

• Subgrade is stable; engineering consultation not required

• Site has access for concrete truck and stamping tools

• {{client_name}} selected stamp pattern from {{contractor_name}}'s pattern library

Any modification to the scope, specifications, materials, or schedule set forth in this agreement must be authorized in writing as a Change Order signed by both parties before the work is performed. Each Change Order will describe the modified scope, any adjustment to the contract price, and any impact on the schedule. Verbal instructions do not modify this agreement. Additional time and cost associated with unforeseen conditions — including but not limited to concealed rot, asbestos, mold, faulty prior installation, unmarked utilities, or code-required upgrades triggered by the work — will be documented as a Change Order and billed at the rates stated in this proposal or at {{contractor_name}}'s then-current published labor rates, whichever is in effect at the time the condition is discovered.

{{contractor_name}} warrants the workmanship of the installed work for a period of one (1) year from the date of substantial completion. Manufacturer warranties on materials and equipment pass through to {{client_name}} as provided by the manufacturer and are the exclusive source of any material warranty. This warranty does not cover normal wear, abuse, neglect, acts of God, subsequent work performed by others, damage from settlement or movement of the building, or modifications to the installed work performed without written consent. To make a warranty claim, {{client_name}} must notify {{contractor_name}} in writing within thirty (30) days of discovering the alleged defect and allow reasonable access to inspect and repair.

This proposal is valid for 30 days from the proposal date ({{proposal_date}}). Pricing is subject to change after that date due to material market fluctuations and scheduling availability. Acceptance requires signature below and receipt of the deposit amount stated in Payment Terms. Upon acceptance, this proposal, together with any attached specifications and subsequent written Change Orders, constitutes the complete agreement between the parties and supersedes any prior oral or written discussions.
