The questions our support inbox actually gets.
Does it ship the same day?+
Orders placed before 2 PM ET on a business day leave the same day from our bench in Altamonte Springs, FL. Tracking is emailed the moment the label prints.
What if it's the wrong size for my building?+
Return it. 30 days, no restocking fee, refund to the original payment method. Better: send us your floor plan first and we'll size the kit for free — half of all returns are sizing problems.
Who handles the warranty?+
We do. Everything carries the manufacturer's warranty and we run the claim for you — one email to us instead of a ticket queue overseas.
How does the bundle discount work?+
Add items to a kit in the bundle builder: 2+ items saves 5%, 3+ saves 8%, 4+ saves 12%, and 5+ saves 15% off the whole kit.
