Siding Contractor Proposal Template: Win More Jobs Without Lowering Your Price

Siding jobs are big-ticket. Homeowners spend weeks getting quotes, comparing notes, and second-guessing every contractor. The ones who send a clear, professional proposal while the competitor is still "working up the numbers" win a disproportionate share of the business.

This guide covers exactly what a winning siding proposal looks like, how to structure your pricing, and what to include to protect yourself legally.

What a Strong Siding Proposal Includes

A good siding proposal does two things at once: it makes the customer feel confident about hiring you, and it protects you if something goes sideways mid-job.

Here's what every solid siding proposal should cover:

1. Job Summary

Write it in plain language. No trade jargon, no product codes. Homeowners want to understand what they're paying for.

Example:

Remove and dispose of existing vinyl siding on all four elevations. Install approximately 1,800 sq ft of LP SmartSide 8-inch lap siding with 1/2-inch foam insulation board backing. Includes all corner trim, J-channel, and window/door trim. Caulk and prime all exposed wood trim.

2. Itemized Costs

An itemized quote almost always converts better than a flat price. When customers understand what each line costs, they stop negotiating on total price and start seeing the value.

Item	Qty	Unit Price	Total
LP SmartSide 8" lap siding	1,800 sq ft	$3.20/sq ft	$5,760
1/2" foam insulation board	1,800 sq ft	$0.85/sq ft	$1,530
Corner trim (6 corners)	6	$85	$510
J-channel and window trim	lot	—	$420
House wrap / moisture barrier	1,800 sq ft	$0.45/sq ft	$810
Fasteners, caulk, flashing	lot	—	$280
Old siding removal + disposal	1,800 sq ft	$1.10/sq ft	$1,980
Labor – installation (4 crew, 3 days)	96 hrs	$65/hr	$6,240
Permit	1	$195	$195
Total			$17,725

3. Scope Boundaries

This section prevents the most common source of post-job disputes. Be specific about what is and isn't included — if you leave it ambiguous, customers will fill the gap in their favor.

Included:

• Removal and disposal of existing siding
• New siding installation on all four elevations
• Foam insulation board backing
• All corner trim, J-channel, and window/door trim
• House wrap installation
• Caulking at all penetrations and trim joints

Not included:

• Rotted sheathing repair (to be quoted separately if found during demo)
• Window or door replacements
• Fascia, soffit, or gutters
• Painting or staining (LP SmartSide comes primed; finish coat not included)
• Any structural repairs revealed during siding removal

4. Material Specifications

Siding has a wide price range. Specifying the exact product you're bidding eliminates the "can you use something cheaper?" conversation and establishes your recommendation as professional.

Example:

Siding: LP SmartSide 8-inch Smooth Cedar lap siding, primed. Manufacturer 5/50 limited warranty (5 years workmanship, 50 years structural, 5 years trim).

Insulation board: Owens Corning 1/2" FOAMULAR rigid foam, R-3.

House wrap: Typar HomeSeal HB, 9-month UV exposure rating.

5. Warranty & Guarantee

Spell out both your labor warranty and the manufacturer's coverage. Most competitors skip this entirely — including it sets you apart as the serious option.

Example:

2-year labor warranty on all work performed. Defects in workmanship resulting in water intrusion will be remediated at no charge within the warranty period. LP SmartSide carries a 5-year limited warranty on workmanship and a 50-year limited structural warranty.

6. Timeline

Give a realistic start-to-finish window. Vague answers like "a few weeks" lose jobs to contractors who give a firm date.

Example:

Estimated project duration: 3 working days. Work to begin within 5 business days of signed proposal and deposit receipt. Schedule subject to material availability and weather.

7. Payment Terms

Clear payment terms get you paid faster and filter out flaky customers before the job starts.

Example:

30% deposit required to hold schedule slot and order materials. 40% due at project start (Day 1). Balance due upon completion and walkthrough. Accepted methods: check, e-transfer, or credit card (3% processing fee).

How to Price Siding Work

Siding pricing has a few moving parts that trip up newer contractors:

The four cost buckets:

1. Materials — Siding, trim, insulation board, house wrap, fasteners, caulk. Get your actual supply cost and apply a 25–35% markup for handling, storage, and warranty coverage.
2. Labor — Most siding crews price by the square (100 sq ft). Typical range: $1.50–$3.50/square for labor-only depending on complexity, story height, and material type. Fiber cement runs higher than vinyl.
3. Demo and disposal — Factor in dumpster rental or haul-away fees. Don't absorb this cost into your hourly rate; line-item it so the customer sees it.
4. Overhead — Licensing, insurance, vehicle, equipment. If you're not building this into your square footage price, you're working for less than you think.

The height premium: Second-story and above work requires ladders, scaffolding, or a lift. Price it accordingly — at minimum 20–30% premium on labor for second-story elevations.

The rot wildcard: Always include a line in the proposal language that says "rotted or damaged sheathing discovered during demo will be repaired at [$/sheet or $/hr] with client approval." This protects you from absorbing a hidden cost that's genuinely the customer's problem.

The 3-Tier Strategy That Closes More Siding Bids

Presenting three options gives customers the perception of choice while anchoring them toward your preferred middle-tier product.

Example — Full house re-siding:

Option	Product	What's Included	Price
⭐ Basic	Standard vinyl	Siding + basic trim	$12,800
⭐⭐ Better	LP SmartSide	Siding + foam board + full trim + 50yr warranty	$17,725
⭐⭐⭐ Premium	James Hardie fiber cement	Full Hardie plank + ColorPlus factory finish + trim + 30yr warranty	$23,400

Most customers pick the middle. You've educated them on the tradeoffs and positioned yourself as a knowledgeable contractor — not a commodity bidder.

What Siding Contractors Get Wrong in Their Proposals

1. No material specs. "Vinyl siding — 1,800 sq ft" tells the customer nothing. What brand? What profile? What color? Ambiguous specs invite comparison shopping and negotiation.

2. Not addressing the rot risk. Every experienced siding contractor has opened up a wall and found a mess. If your proposal doesn't address this, you're either absorbing the cost or having an ugly conversation mid-job.

3. One price, no options. Customers who want the cheapest option will always find a cheaper contractor. Giving them three tiers positions you as the premium option and gives budget-conscious customers a lower entry point without you cutting margin.

4. Slow turnaround. The homeowner who called three contractors on Monday is signing with whoever responds first by Wednesday. Waiting until end of week costs you the job.

5. No e-sign. Printing, signing, scanning, and emailing a PDF is friction. Every extra step is a reason for a customer to procrastinate. A link they can sign on their phone from the couch closes same day.
