Frequently Asked Questions
Are these calculators really free?
Yes. Every tool on this page is completely free to use, with no cost and no obligation. You'll get an instant planning estimate, and it's entirely up to you whether you follow up for a free on-site visit and written quote.
How accurate are the estimates?
Each calculator is built on the same real pricing we publish on our service pages — not generic national averages. That makes them a solid planning estimate, but every property is different, so we always confirm exact pricing with a free on-site walkthrough before any work begins.
Do I have to submit my information to see a price?
Yes — we ask for your name and either an email or phone number before revealing your result, so we can save your estimate and follow up if you'd like a written quote. We never require a credit card or any payment information.
What happens after I submit a calculator?
Your estimate is saved and our team is notified right away. If you'd like next steps, we'll reach out by phone, text, or email — typically within 24–48 hours — to schedule a free on-site visit and send a written, line-item quote.
Which tool should I use for my project?
Start with whichever calculator matches your project — lawn care tools for mowing, seeding, and sod; Build & Outdoor Living tools for patios, decks, and permits; Exterior Cleaning tools for pressure washing, house washing, and gutters. Not sure? Call or text us and we'll point you to the right one.
Are the pricing ranges the same as your final quote?
They're a close planning estimate, not a final quote. Your exact price depends on details a calculator can't see — access, site condition, exact materials — which is why every project gets a free on-site visit and a written, line-item quote before we start.
Do you offer tools for lawn, hardscape, and exterior cleaning?
Yes. We have 24 free tools across all three of our service families: Lawn Care & Landscaping, Build & Outdoor Living, and Exterior Cleaning — covering everything from mowing and mulch to decks, patios, permits, pressure washing, and gutters.
