BidBase gives you professional-grade construction cost estimates — itemized, location-adjusted, and explained in plain English. From a deck repair to a full addition. No contractor consultation required.
Answer a short series of guided questions. Tell us what you're building, the approximate size, and your location. No blueprints needed.
Our AI produces a complete cost breakdown — materials, labor, permits, overhead — with local pricing that reflects your zip code and current market conditions.
See how your estimate stacks up against similar projects in your area, submitted by real contractors and homeowners. Transparency builds confidence.
Use your BidBase estimate to negotiate with contractors, scope your own DIY build, or budget for the project you couldn't previously price.
Our AI asks the right questions so you don't have to know what you don't know. Most people under-scope their projects — BidBase corrects that automatically.
Every line item is broken out by category — materials, labor, equipment, permits. Not one big number. The actual build cost, explained.
See what other builds like yours actually cost in your zip code. Real data from real projects — not national averages that don't apply to your market.
Getting a construction estimate used to mean one of three things: hiring a designer, paying $300 for a contractor consultation, or guessing with a Home Depot calculator and hoping for the best.
Contractors have professional estimating software. Homeowners have guesswork.
That's the gap BidBase closes.
If you're a DIYer who wants to know whether a bathroom remodel is a $6k or $20k project before you tear anything out — BidBase is for you. If you're a contractor who needs a fast, defensible estimate to share with a client — BidBase is for you too.
The same platform. Both audiences. One clear number.
Stop guessing. Stop overpaying. Stop being surprised. BidBase puts professional-grade construction cost intelligence in your hands — before you sign anything, spend anything, or commit to anything.
