How a Mariano project runs

Each project gets the attention it deserves. We work closely with every customer, communicating at every step, to make sure we meet their vision.

  1. STEP 01

    Walk the site

    We meet you at the property, talk through what you want, and give you a free estimate — no obligation.

  2. STEP 02

    Plan & price

    Floor plans, material options and a written scope, so the budget and the schedule are agreed before anyone swings a hammer.

  3. STEP 03

    Build

    All of our subcontractors are hand picked to keep every element of the project up to the highest standards.

  4. STEP 04

    Hand over

    A final walk-through together, and a company that stands behind every project it works on.

Chris understood the insurance process and took a huge burden off us. He gave us a date for when we would move back into our beach house and he was right on time. His craftsmanship is above what our expectations were.
