    Common Questions

    Home renovation FAQ.

    HOW MUCH DOES A HOME RENOVATION COST?+
    Home renovation costs vary dramatically by project type and scope. SMALL PROJECTS (room refresh, flooring, paint): $5,000–$15,000 MEDIUM PROJECTS (basement finish, room addition, open-concept): $20,000–$50,000 LARGE PROJECTS (whole-house renovation, multi-room additions): $50,000–$150,000+ PREMIUM PROJECTS (luxury master suite, major structural work): $100,000–$300,000+ Cost depends on: - Square footage of renovation - Material quality (basic vs. premium) - Structural changes needed - System upgrades (electrical, plumbing, HVAC) - Local labor costs (~$44/hour in Wisconsin) Typical cost breakdown: 40% materials, 50% labor, 2% permits, 10% contingency Your exact quote is always itemized. We never surprise you with hidden costs.
    HOW LONG DOES A HOME RENOVATION TAKE?+
    Timeline depends entirely on scope. Here's what to expect: BASEMENT FINISHING: 8–12 weeks (500–1,000 sq ft) SMALL ROOM ADDITION: 12–16 weeks (200–400 sq ft) KITCHEN REMODEL (within existing space): 8–12 weeks BATHROOM REMODEL: 6–8 weeks OPEN-CONCEPT RECONFIGURATION: 4–8 weeks (+ design time) WHOLE-HOUSE RENOVATION: 16–24 weeks LARGE ADDITION (1,000+ sq ft): 20–48 weeks (5–12 months) TIMELINE INCLUDES: - Design & planning: 3–6 weeks (often parallel with permitting) - Permitting: 2–10 weeks (depends on city approval) - Construction: 4–20+ weeks - Final inspections & punch-list: 1–2 weeks Factors that extend timelines: - Material delays (cabinets, windows, specialty items) - Permit delays (city-dependent) - Weather (Wisconsin construction challenges) - Unexpected structural issues in older homes - Change orders mid-project We always build in 20–30% contingency time for real-world delays. We keep you updated weekly throughout the project.
    CAN WE LIVE IN THE HOUSE DURING RENOVATION?+
    Yes — for most renovations, you can stay home during work. BASEMENT FINISHING: ✓ YES — work is self-contained. Minimal disruption to main floor. ROOM ADDITION: ✓ YES — work is exterior. Dust containment keeps home clean. WHOLE-HOUSE RENOVATION: ⚠️ PARTIAL — Depends on scope. Kitchen remodels = temporary kitchen setup. Bathroom remodels = use guest bath. Multi-room work = some rooms off-limits. Most families stay; some prefer short-term relocation during worst weeks. OPEN-CONCEPT RECONFIGURATION: ⚠️ DEPENDS — If it involves removing walls that affect living areas, temporary arrangements may be needed for 2–4 weeks during structural phase. BEST PRACTICES: - We seal off work areas with plastic containment - We manage dust control carefully - We schedule messy work (demo, sanding) early in project - We coordinate around your schedule - We set clear "no-work" hours (typically 7am–5pm weekdays) Most families find staying home totally manageable. We help minimize disruption.
    WHAT ABOUT PERMITS AND INSPECTIONS?+
    Wisconsin requires permits for almost all renovations. We handle everything. PERMITS REQUIRED FOR: ✓ Structural changes (removing walls, adding rooms) ✓ Electrical work (new circuits, panels, major rewiring) ✓ Plumbing changes (new bathrooms, water lines) ✓ HVAC modifications (new systems, ductwork) ✓ Basement finishing (requires egress window inspection) ✓ Room additions (always required) OUR PROCESS: 1. We submit complete plans to the City 2. You never talk to the city — we do 3. Plan review: typically 1–4 weeks 4. We schedule inspections at key phases: - Framing inspection - Electrical rough-in inspection - Plumbing rough-in inspection - Final inspection 5. We coordinate all inspections and ensure code compliance 6. You get final permit sign-off PERMIT COSTS: Typically $100–$300 depending on project scope. Always included in your estimate. TIMELINE IMPACT: Permits add 2–10 weeks, depending on city and how complete your plans are. We account for this in your project schedule.
    WHAT IF WE FIND HIDDEN DAMAGE DURING RENOVATION?+
    This happens often in older Wisconsin homes. We're prepared for it. COMMON DISCOVERIES: - Rotted subflooring or wall framing - Old galvanized pipes (pre-1980s homes) - Knob-and-tube electrical wiring (outdated, unsafe) - Mold or water damage from prior leaks - Structural settling or foundation issues - Asbestos in old insulation or flooring HERE'S HOW WE HANDLE IT: 1. We stop work and photograph the issue 2. We explain what we found and why it needs fixing 3. We estimate cost and timeline impact 4. We get your written approval before proceeding 5. We fix it properly to code BUDGET BUFFER: We always recommend a 10–15% project contingency for exactly this reason. Older homes deserve careful inspection, and surprises are often small fixes once addressed. Better to fix it now than deal with bigger problems later. We've worked hundreds of Wisconsin homes. We know what to expect and plan accordingly.
    HOW DO WE CHOOSE MATERIALS AND FINISHES?+
    Material selection happens during the design phase—before construction starts. OUR APPROACH: 1. We show you samples of flooring, paint, trim, fixtures 2. We explain pros/cons of each option 3. You choose based on style, durability, and budget 4. We lock in selections before ordering MATERIAL CATEGORIES: FLOORING: Luxury vinyl ($2–$5/sf) · Tile ($3–$8/sf) · Hardwood ($6–$12/sf) PAINT: Quality exterior paint ($25–$40/gallon) · Interior latex ($20–$35/gallon) FIXTURES: Budget ($50–$200 each) · Mid-range ($200–$500) · Premium ($500–$2,000+) CABINETS / BUILT-INS: Stock ($3K–$8K) · Semi-custom ($8K–$15K) · Custom ($15K–$50K+) We help you balance aesthetics with budget. Premium materials don't always mean better value—we guide you toward choices that last decades. Your material choices are finalized in writing before we start construction.
    WILL MY HOME'S VALUE INCREASE?+
    Yes — strategic renovations significantly improve home value and appeal. BEST ROI (Return on Investment): - Kitchen remodel: 50–75% ROI (homeowners recover most costs) - Bathroom remodel: 60–80% ROI - Basement finishing: 70% ROI - Room addition: 65–85% ROI (varies by square footage) - Open-concept reconfiguration: 50–70% ROI - Energy upgrades (HVAC, insulation, windows): 80% ROI These numbers mean: if you spend $30K on a bathroom, you'll typically recover $18K–$24K of that value when you sell. BEYOND VALUE: Even if future ROI is modest, renovation improves daily living: ✓ Modern, functional spaces ✓ Better energy efficiency (lower utility bills) ✓ Increased home comfort ✓ Fewer maintenance headaches ✓ Ability to accommodate growing family A good renovation is as much about quality-of-life today as future resale value.
