Start-to-finish roadmap
What to do—and in what order.
Use this as the main path through the guide. Each step produces something useful for the next one, so you are not collecting prices before the project is clear.
- 01
Define the finished result
Write the project size, performance goal, material level, work included, and work intentionally excluded. Start with: Removal and concealed repairs; Weather barrier and flashing.
Leave with one written scope - 02
Inspect before pricing
Ask bidders what they can verify now and what remains unknown. Pay special attention to existing wall condition and siding system.
Turn unknowns into questions or allowances - 03
Build the complete budget
Use the calculator for a first-pass range, then add design, permits, engineering, temporary protection, owner selections, and a separate contingency where they apply.
Set a working budget, not just a bid target - 04
Confirm the approval path
Describe the exact scope to the municipality. Ask which building, trade, zoning, site, or other reviews apply and which inspections must happen before work is covered.
Record who applies, pays, and schedules - 05
Compare the same project
Give every bidder the same scope and require written answers about siding system and accessories, insulation and ventilation details, trim, penetrations, and restoration. Compare exclusions and allowances before comparing totals.
Compare the same written scope before choosing - 06
Control construction and closeout
Tie payments to visible progress. Track approved changes, inspection results, punch-list work, final approvals, manuals, warranties, photos, and lien documents before final payment.
Finish with a complete project file
Write a one-paragraph project description and list the three decisions you have not made yet. Do that before requesting the first quote.
Then build the budget →Choose your planning path
How involved do you want to be?
Choose the route that matches your role today. Both paths use the same budget, permit questions, and written scope, so you can change direction without starting over.
I plan to hire a contractor
Good fit when: you want one or more contractors to price and complete the installed project.
- Give every bidder the same written scope.
- Compare removal and concealed repairs, weather barrier and flashing, siding system and accessories.
- Check exclusions, allowances, payments, warranties, and closeout.
I may handle selected prep or finish work
Good fit when: you want to organize decisions, products, bids, or permit calls before assigning the work.
Confirm who handles removal, sheathing repairs, weather barrier, insulation, flashing, trim, access, permits, cleanup, and warranties.
Build the permit call list →HomeScope provides planning information, not construction instructions, structural design, code approval, or a determination that work is safe or eligible for owner performance. Confirm the project-specific path with the responsible municipality and qualified professionals.

How the cost works
Start with quantity—then add the work a unit price misses.
The calculator is transparent arithmetic, not a market quote. It multiplies the measured planning quantity by the published base range and selected community adjustment. A written proposal must then define the real products, labor, conditions, allowances, exclusions, and approvals.
Confirm how the quantity was measured and what waste or inaccessible areas are included.
Per exterior wall square foot, before the selected community adjustment.
A broad planning adjustment for Troy, not a contractor quote or observed local bid.
Existing wall condition, Siding system, Trim and transitions, plus documented unknowns and exclusions.
Then verify the complete project with written local bids and add a separate contingency appropriate to the known risks.
Use current product prices to test a material allowance.
Panel prices omit removal, wall repairs, weather management, trim, access, delivery, waste, installation, permits, and restoration. A trustworthy snapshot names the exact product or dimensions, retailer or manufacturer, observation date, location limits, and everything excluded. It should not silently replace an installed-cost range.
Worked examples

These examples use the current base range and the Troy 1.08 local planning adjustment. They are arithmetic examples—not observed bids—and keep cost-changing choices visible.
1,200 exterior wall sq. ft.
$10,400–$31,100Measured wall area before openings and waste.
1,800 exterior wall sq. ft.
$15,600–$46,700Measured wall area before repairs and trim complexity.
2,600 exterior wall sq. ft.
$22,500–$67,400Measured wall area before repairs and premium materials.
Perimeter × average wall height
Example: 160 ft × 9 ft = 1,440 exterior sq. ft. Add gables separately and require every bidder to state how openings and waste are handled.
Window-count examples
Planning windows too? Use their own calculator.
Siding estimates exclude windows because opening count and installation method need a different model.
National reference, not a Michigan quote. Full-frame work, damage, access, and trim can cost more. ConsumerAffairs ↗ ENERGY STAR ↗
Do not add these examples to a contractor's quote without checking what that quote already includes. Use measured quantities, a written product specification, and local bids for the actual decision.

Budget drivers
What moves the final price.
Existing wall condition
Removal can reveal sheathing, framing, insect, moisture, and flashing problems that need unit prices or allowances.
Siding system
Vinyl, engineered wood, fiber cement, metal, insulation, rainscreen details, fasteners, and finish affect labor and materials.
Trim and transitions
Corners, openings, penetrations, roof-wall intersections, mounting blocks, soffits, and fascia should be named instead of hidden in a lump sum.
Water management
Housewrap, flashing tapes, pans, kickout flashing, penetrations, and transitions determine long-term performance.
Permit planning
A checklist before work begins.
- Confirm permit requirements for siding removal, exterior-envelope work, insulation, and structural repairs.
- Ask whether product approvals or energy documentation must be submitted.
- Clarify inspection timing before weather barriers, flashing, insulation, or repairs are concealed.
- Confirm responsibilities for lead-safe work or other rules that may apply to the home.
- Keep product labels, photos of concealed flashing, inspections, and warranty registrations.
Better bids
Questions for every contractor.
- What removal, disposal, sheathing inspection, and repair unit prices are included?
- Which siding, insulation, weather barrier, fasteners, accessories, and finish are specified?
- How are openings, penetrations, roof-wall intersections, and water management detailed?
- Which caulks, flashings, trim coils, mounting blocks, and color-match items are included?
- How will landscaping, utilities, entries, and occupied areas be protected?
- How do workmanship and product warranties interact?
