The Problem
The human brain is wired to underestimate. Projects take longer. Materials cost more. Skill gaps are invisible until they aren't.
45% completely butcher a project beyond repair — then pay for materials twice to start over.
When DIY projects blow the budget, they end up costing twice what the homeowner originally planned.
After wasted weekends and ruined materials, 1 in 3 DIYers call a contractor to fix their own work.
The Data
Every stat below is drawn from independent research on real DIY projects. This is what happens when homeowners go in without a plan.
The average overdue DIY project consumes 22 more hours of labor than the homeowner anticipated.
Floor installations top the list at a 40% regret rate — followed by room additions and cabinet work.
Not cost overruns — outright mistakes that force homeowners to scrap work and buy materials twice.
Credit cards, personal loans, and family money are the fallback when a DIY project falls apart.
87% of millennial homeowners have unfinished repairs — and 84% are actively putting them off.
Half of homeowners report that unfinished projects create chronic stress and anxiety in daily life.

Features
Receive an objective Go, Caution, or Stop recommendation before you start. The Sage conducts a focused Q&A to assess true project complexity — returning a Feasibility Score, primary risk, skill jump required, and the sweat equity you'll save.
Stop relying on single-point guesses. Our engine runs 5,000 simulations to model both time and cost uncertainty simultaneously, returning honest p50/p85/p95 ranges — not a best-case lie.
Set your available weekend hours and build your plan using real forecast data. Large projects automatically split into sequenced phases across weekends to protect your free time.
Every completed project adds to your permanent Sweat Equity Ledger — the real dollar value of professional labor you saved by doing it yourself. Track equity, hours, and unlock badges.
Point your camera at any project area. The AI identifies the task, estimates scope, and pre-loads your consultation instantly. Available on Master Builder.
Turn any Sage consultation into a shareable document: feasibility score, verdict, pro vs. DIY cost comparison, sweat equity, time ranges, risk profile, and materials list.
How It Works
Enter what you want to build, your budget, and risk tolerance. Optionally, point your camera at the project space and let Sage Vision do the rest.
Our probabilistic engine models your project across thousands of scenarios, accounting for skill gaps, material costs, complexity, and the unexpected.
Receive a Go, Caution, or Stop verdict with a realistic time and cost range — not an optimistic guess. Then build your weekend plan with real data.
