Frequently Asked Questions

Here are answers to some common questions. Reach out if we’ve left anything out!

What is the turn-around time for products?

Usually all products are ready two to three days after the building scan is performed. Large jobs may take a little longer, but we will let you know if that may be applicable to your job.

Does someone need to be present for the appointment?

Totally up to you! As long as we have access to the property, we don’t need someone to be there. We will reach out to confirm if someone will be there or for access instructions.

How long does the measurement process take?

The LiDAR scanning process is fast! Plan for a ~1500 sqft home to take about 15-30 minutes start to finish. Multiple levels may add some time. Time to measure essentially scales linearly with sqft.

Does the property need to be prepared in any way prior to the appointment?

Generally no special preparations need to be made to the property; furniture, appliances, and other objects can stay right where they are. We will open all doors including closets, pantries, bathrooms, etc. to ensure all interior and exterior wall thicknesses are documented.

When will I receive the products and how are they delivered?

As soon as we compute the measured square feet, we will send you an invoice (usually 2-3 days after measurements are taken). Once the invoice is paid, we’ll send your products via email (or download link depending on size).

Why haven’t I outsourced building measurements and drafting before now!?

We’re as perplexed as you are! Know your property, save time, reduce risk, and avoid costly mistakes.
