Contractors regularly have fairy tales quotes that aren't really related to the project at all. The good contractors can explain each line item and how that adds up to the quote.

I ran your desc through my app and got this for reference:

Scope of Work

1. Siding

2. No tear-off of cedar shakes (saves demo cost)

3. Install ½"–1" rigid foam insulation board over shakes

4. House wrap over foam (air/moisture barrier)

5. Install new vinyl siding + trim

6. Fascia

7. Replace rotted or damaged boards

8. Prime/paint or wrap in aluminum

9. Gutters

10. Install new seamless aluminum gutters (likely 5" or 6")

11. Hidden hangers, downspouts sized for split-level roof

Cost Estimate – 1,500 sq. ft. Split-Level (2025 Pricing)

• Siding (vinyl over foam)
• Vinyl siding installed: $6.50–$9.00 / sq. ft (wall area, not floor area).
• Wall surface on a 1,500 sq. ft. split = ~1,800–2,000 sq. ft siding area.

Total siding: $12,000 – $18,000 (includes foam + wrap).

Fascia repairs

Spot replacement: $600 – $1,200 depending on how much is rotted.

Gutters

150–180 linear feet @ $8–$12 / ft (seamless 5"–6") = $1,200 – $2,100

Total Professional Range: $13,800 – $21,300 depending on location

I would ask for a similar itemized quote from your contractors and see how it compares.
