What's not in the cost ranges
Four line items commonly show up on whole-home remodels that the initial budget didn't capture:
- Roof replacement. A whole-home remodel is often the right time to replace a 20+ year-old roof. $15,000–$45,000 depending on size and material.
- HVAC system replacement. Manual J recalc + new air handler + ductwork rebalance: $8,000–$25,000.
- Panel and service upgrade. Older Clay County homes commonly need 200A panel and possibly meter base upgrade. $4,000–$8,000.
- Temporary housing during construction. Rental for 8–18 months: depends on market.
Why design-build is the right model for this scope
Whole-home remodels involve more coordination than any other residential project type. A 12-trade sequence that runs cleanly with a design-build contractor like Tivey can become a 6-month delay when the homeowner is coordinating an architect, a builder, and 8 separate sub-trades.
Mark's design-build process puts every line of the project on one contract: architecture, structural engineering, mechanical design, all permits, all trade work, all warranty. The homeowner has one phone number to call. That single-source accountability is what turns an 18-month potential disaster into a 14-month finish-on-schedule project.
Where the time goes
For a typical 12-month whole-home remodel:
- Months 1–2: Design, engineering, HOA review, permit application
- Months 3–4: Permit issuance, demo, structural work, foundation/slab repair if any
- Months 5–6: Roof + exterior, rough framing, rough plumbing/electrical/mechanical
- Months 7–8: Insulation, drywall, drywall finish, exterior paint
- Months 9–10: Floor, tile, cabinet install, paint
- Month 11: Counter template + fabrication + install, plumbing trim, electrical trim
- Month 12: Punch list, appliances, final inspections, Certificate of Occupancy
Weather, supply chain, and HOA review all add risk. A 2–4 month buffer is realistic.
