FAQ's

Get answers to the questions we hear a lot

Do you offer free quotes or assessments?

Yes, we provide free, no-obligation quotes for all our masonry cleaning, sealing, and protective coating services. We can give you an estimate based on the details you provide via phone or email, but for the most accurate pricing, we recommend an on-site assessment.

How long do your sealers and coatings last?

Our high-performance sealers and coatings are designed for long-term protection. Lifespan varies based on factors such as surface type, environmental conditions, and maintenance. In general, our penetrating sealers can last between 5-10 years, while anti-graffiti coatings and waterproofing systems provide durable, lasting protection with proper care.

Are your products eco-friendly?

Yes, sustainability is a core part of our mission. Our sealers and coatings are formulated to be low-VOC, non-toxic, and environmentally safe, ensuring strong protection without harming the surrounding ecosystem.

Can your products prevent efflorescence and staining?

Absolutely. Our advanced masonry sealers create a breathable barrier that prevents moisture intrusion, significantly reducing the risk of efflorescence, staining, and surface degradation. For existing efflorescence issues, we also provide specialized removal services.

How does your waterproofing system work?

Our liquid waterproofing solutions penetrate deep into masonry and concrete surfaces, forming a hydrophobic barrier that repels water while allowing the substrate to breathe. This prevents cracking, moss growth, and long-term water damage.
