FAQ

Frequently Asked Questions

Can interlocking stairs be built on a steep slope?

Yes. We specialize in grade management. We use heavy-duty landing stones and structural retaining units to build safe, elegant stairs that navigate elevation changes. Our focus on proper footings ensures your stone steps won't tilt or shift over time.

How do you ensure water doesn't pool on my new patio?

During the grading phase, we establish a precise slope (typically a 1-2% grade) away from your home's foundation. This ensures rainwater and snowmelt flow naturally into your lawn or drainage system, keeping your entertainment area dry and protecting your foundation.

What is the benefit of interlock over a traditional wooden deck?

Interlock is a permanent, fire-safe solution that won't rot, splinter, or require the annual staining and sanding that wood decks do. It provides a natural, high-end look that integrates perfectly with your landscaping and significantly increases your home's resale value.

Can I add features like a fire pit or outdoor kitchen to my interlock patio?

Absolutely. Because interlocking stone is non-combustible and incredibly strong, it is the ideal foundation for fire pits, heavy pizza ovens, and outdoor kitchens. We can even reinforce specific areas of the base to support the additional weight of these features.

How long does the installation of a patio and walkway usually take?

Most backyard transformations are completed within 4 to 8 days, depending on the size and the amount of intricate cutting or stair work involved. Our goal is to work efficiently so you can begin enjoying your new outdoor lifestyle as soon as possible.
