About Peter’s General Construction LLC / DBA One Call 24-7

Building Trust. Restoring Homes. Rebuilding Lives.

For over 25 years, Peter’s General Construction LLC — operating as One Call 24-7 — has been New Jersey’s most trusted roofing, restoration, and construction company.
But our story begins long before the business.

Our Origin Story

I, Pedro Guaman, started life with nothing except the values my family gave me — faith, honesty, work, and integrity.
I grew up with need, wearing old shoes and learning early what it means to live without. My grandmother taught me a truth that became my life principle:
“If someone helps you, share everything.
But if someone refuses to help others, even if you have extra, do not reward injustice.”
In 2020, my life was shaken again. I became severely ill for months. Doctors said I would never recover without lifelong medication.
But God Himself spoke to me one afternoon in Hillside, NJ, telling me I no longer needed the medicine — that He would restore me.
And he did.
From that moment, I knew my mission and purpose:
to use my work, my company, and my life to help families, restore homes, and bring real hope to people.
This company is not just a business.
It is a calling.

Call us anytime — we’re there 24/7 to help you!
