Protection
We help you avoid costly mistakes, hidden costs, and poor planning that derail renovation projects.
Why Kestim beats ChatGPT for renovation advice.
While ChatGPT is a powerful general-purpose AI, it lacks the specialized knowledge, localized data, and renovation expertise that Kestim provides. Here's why homeowners choose us.
Generic AI
- •Trained on generic internet data from 2021-2023
- •No access to real-time local pricing data
- •Cannot analyze your specific property photos
- •Provides generic estimates that vary wildly
- •No verification of contractor quotes
Kestim
- •Specialized exclusively in real estate & renovation
- •Live pricing data across Belgium, France, NL, Luxembourg
- •Analyzes your actual property photos & documents
- •Accurate estimates based on CSTC technical reports
- •Compares real contractor quotes line-by-line
Insider Knowledge
Access to CSTC technical reports, industry benchmarks, and real contractor pricing databases that ChatGPT has never seen.
12+ Years Experience
Founded by contractors and renovation experts with over a decade of hands-on field experience, not just AI training.
Laser Focus
We do one thing exceptionally well: renovation analysis. No general knowledge, no distractions, just expertise.
Privacy First
Your quotes, photos, and project details are never shared with third parties or used to train public AI models.
Structured Reports
Get a professional PDF report with clear sections, risk assessments, and actionable insights—not a chat conversation.
Always Current
Our pricing data is regularly updated with current market rates, material costs, and regional variations.
Remove the fear, confusion, and vulnerability homeowners feel when planning renovations.
Most homeowners face the same problems when renovating: they have no idea what things should cost, every contractor tells them something different, and they don't know how to compare quotes or what's missing.
Kestim exists to give homeowners clarity, independence, and peace of mind — before they talk to any contractor.
We combine AI-powered analysis with real renovation expertise to deliver architect-level clarity at a fraction of the cost of traditional consulting.
