FAQs
How do I know if my building needs waterproofing?
Signs include stucco cracking, interior moisture stains, spalling concrete, failed joint sealants, and recurring water intrusion after heavy rain.
Is waterproof coating the same as roof repair?
No. Our systems focus on exterior walls, balconies, walkways, and structural concrete. Roofing systems are separate.
Can you work nights or around business hours?
Yes. For retail, hospitality, and office environments, we coordinate after-hours or low-traffic scheduling when needed to reduce operational impact.
Are you insured and able to provide COI documentation?
Yes. We carry appropriate commercial insurance and can provide certificates of insurance and documentation as required by property managers, HOAs, or general contractors.
How do you handle change orders or unexpected repairs?
Properly installed elastomeric systems can last 10-15 years depending on exposure and maintenance.
How long do commercial waterproof coatings last?
If additional repairs are identified during preparation, we document the condition and provide written recommendations before proceeding. Nothing is added without review and approval.
