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, window product and installation method, trim and interior repairs. 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 buy products or handle finish work
Good fit when: you want to organize decisions, products, bids, or permit calls before assigning the work.
Confirm insert versus full-frame work and who handles flashing, weather barrier, insulation, trim, repairs, access, permits, 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.
Local cost calculator
Build a first-pass Michigan budget.
The calculator models siding by exterior wall area. Window quantity and type, concealed sheathing damage, trim complexity, insulation, flashing, and product selection require separate bid detail.
Based on 1800 exterior sq. ft., a broad local planning adjustment.
Compare contractor bids →This is not a quote, appraisal, or promise of market pricing. It excludes some design, permit, engineering, financing, concealed-condition, premium-finish, and temporary-living costs. Obtain written local bids.
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 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, Window specification, 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.
Unit prices omit removal, flashing, trim, repairs, access, delivery, waste, installation, permits, and interior 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
See what the range means for a defined project.
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 sq. ft.
$10,400–$31,100Measured wall area before openings and waste.
1,800 exterior sq. ft.
$15,600–$46,700Measured wall area before repairs and trim complexity.
2,600 exterior 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
Keep windows in a separate budget bucket.
Siding estimates exclude windows. These national examples use standard 3 × 5 ft replacement openings at $700–$1,200 installed each.
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.
Window specification
Frame material, glass package, operation, size, installation method, trim, and interior repairs should be named.
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, window replacement, altered openings, and structural repairs.
- Ask whether product approvals, energy documentation, or tempered-safety-glass locations must be documented.
- Clarify inspection timing before weather barriers, flashing, 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?
- Are windows full-frame or insert installations, and what interior/exterior repairs are included?
- How are openings, penetrations, roof-wall intersections, and water management detailed?
- Which caulks, flashings, trim coils, and color-match items are included?
- How do workmanship and product warranties interact?
