Questions
Before you request.
Talk it through
(407) 490-0441Tell us the property and where the sale stands. We will tell you what the $89 assessment will show.
Book my $89 drainage assessmentWho is it for?
Buyers, sellers and agents. It is the same $89 drainage assessment for each.
What do I get for $89?
A drainage assessment of the property. A field tech runs it through a 25-year storm simulation in Water MRI, then builds the game plan to fix it: written recommendations, a preliminary drainage design and a quote to install. When we need more accuracy, a 1½–2 hour field assessment is part of it. Final scope and pricing are confirmed in the project quote.
When do I pay?
Not when you request. FAS confirms the details with you first, then collects the $89.
Will someone come to the property?
When we need more accuracy than the model gives, yes: a 1½–2 hour field assessment, with no second fee.
What happens to the $89 if I hire FAS?
It is credited in full, once, within the project's initial one-third deposit. After you approve the scope and price, you pay only the rest of that deposit.
What is Water MRI?
Our own storm software. It builds a model of a property and shows how rain moves across it in a design storm. A planning model.
We have many listings. Is there volume pricing?
Yes. Enterprise accounts get a lower price per simulation and their own dashboard. See enterprise accounts.
