How to Compare Contractor Bids for the Same Rehab Scope

Construction Estimator. How to Actually Get Apples to Apples Bids

🏠 Intro: 3 Contractors, 3 Different Numbers… Who’s Right?

You call three general contractors for estimates.

Each walks your project, each sends a quote and they are 3 different languages.

One is 20% cheaper, one’s double the price, and the third “forgot” to include demolition. So who’s right?

​Truth is, none of them are wrong, they're just bidding with different processes.

📋 Why Estimates Vary So Much

Without a clear scope of work, every contractor is left to guess based off previous experience:

1. What materials you expect. One might bid for subway tile and the other bids for 12x24 tile which is two completely different costs.
2. Which finishes you want. Will you want 3 colors of paint or just 2? Some contractors factor that in while others do not, again different pricing.
3. Poor estimating system and items are missed and will be change orders later…
4. Some simply value their time more than others.

That’s why quotes rarely match. You’re not comparing apples to apples.

🧠 The Fix: Start With a Scope of Work

No experience? No problem

We built an app for folks doing home renovations and need a construction estimate fast but accurate!

“Finally a tool that allows you to build a scope of work during a guided walkthrough — so simple an eighth grader can do it.”

Explore the current app features here: ScopeFirst

A detailed scope eliminates guesstimating.
It spells out exactly what’s included and what’s not, so contractors can price the same job.

Then you can send that same scope to multiple contractors and get pricing that’s finally apples to apples.

Contractors will be blown away when you create a detailed scope of work and project plan with no experience. This is the ultimate cheat code!​

💬 Bottom Line​

The best construction estimator isn’t the one with the lowest number — it’s the one that starts from the right foundation.
That foundation is your scope.
​ ScopeFirst helps investors document the work with guided prompts and photos.
