Apartment Renovation Estimate 2026: How to Create One Without a Surveyor in 15 Minutes

Started a renovation without an estimate — got a final bill 30-40% over budget. Construction material prices rose 20-25% in 2026: ceramic tiles +15%, doors +20%, windows +30%. Without a detailed estimate, contractors add work items as they go and the total becomes unpredictable. A professional estimator charges $150-$500 to prepare one. AI calculator TimeMaterial generates an estimate in 15 minutes.

Key facts

• Average renovation cost in Moscow 2026: cosmetic 200-300 USDT/m2, major overhaul 350-550 USDT/m2
• Without an estimate, overspending reaches 30% of budget — on a 45 m2 apartment that is 500,000+ RUB in unexpected costs
• AI calculator accuracy: 85-95% — comparable to a professional estimator
• A ready estimate is a negotiating tool with contractors — typically reduces the final bill by 10-20%
