HEARTSTONE · Independent owner-side oversight
Heartstone represents owners through the construction, recovery, and completion of exceptional custom homes—protecting design intent, construction quality, key decisions, schedule, and the long-term integrity of the home.
Primary engagement area: Northern Virginia and Washington, DC. Limited engagements nationwide.
Start with the problem
Tell us what is happening. Heartstone will help determine the right level of involvement.
Owner representation from preconstruction and early site work through structure, MEP coordination, close-in, finishes, punch list, and completion.
When schedules slip, punch lists grow, accountability disappears, or the project is drifting toward an ugly closeout.
Technical troubleshooting across structure, electrical, mechanical, envelope, controls, specialty systems, and field conditions.
A deliberate pre-insulation and close-in review of the work that will soon be concealed by insulation and drywall.
Not sure yet?
If you want an independent assessment before deciding on a larger engagement, Heartstone can review the project, identify the conditions that deserve attention, and recommend the appropriate next step.
REQUEST A PROJECT REVIEW →The long view
A home at this level is more than a construction project. It is a legacy—designed around a family, built from exceptional materials, and expected to endure.
Heartstone provides independent oversight before work begins, during active construction, and through completion. We help owners ensure that what is designed is actually built, critical details are not lost in execution, and short-term decisions support the long life of the home.
When drawings, specifications, schedule, or quality begin to drift—or a troubled project needs recovery—the same independent judgment brings the work back into focus.
“Every trade sees its scope. Someone has to see the house.”
Core services
Represent the homeowner across site work, structure, MEP coordination, close-in, finishes, quality control, trade interfaces, punch list, and final completion.
EXPLORE OWNER REPRESENTATION →Organize stalled, disorganized, technically troubled, delayed, or abandoned work and create a practical path toward closeout and handover.
EXPLORE PROJECT RECOVERY →Troubleshoot what exists. Challenge what is being proposed. Bring in the right expert before complexity becomes cost.
EXPLORE TECHNICAL PROBLEM SOLVING →Independent review of framing, MEP, blocking, penetrations, envelope details, and trade interfaces while the work is still visible and practical to correct.
EXPLORE CLOSE-IN REVIEW →Coordinate locations, elevations, alignments, and finish interfaces so trades install the design instead of inventing it in the field.
EXPLORE ARCHITECTURAL MEP LAYOUT →Active concrete-process oversight and pre-framing assessment of layout, elevation, bearing, transitions, and inherited field conditions.
EXPLORE CONCRETE & PRE-FRAMING →Project recovery proof
A distressed Georgetown project did not need more meetings. It needed ownership of the details.
Heartstone organized the deficiencies, coordinated the trades, drove corrections, and moved the project through inspection and final completion.
SEE HOW PROJECT RECOVERY WORKS →Technical case study
The K-valve had already been replaced. The replacement still would not engage. The valve was never the root problem.
On a brand-new alternative septic system, the contractor, engineer, and county had all been involved. The system still did not work. Heartstone traced the problem to the way pressure and flow were being controlled, corrected the operating logic, and got the system functioning without another unnecessary component replacement.

Founder led. Field driven.
Heartstone is founder-led, but not built around one person's ability to do everything.
Clients work with Connor Romanzo Bertoldo as a clear point of leadership while Heartstone coordinates the skilled tradespeople, engineers, designers, specialty contractors, vendors, and technical experts the project actually needs.
The objective is simple: understand the house deeply enough to see the problem early, assemble the right people, make expectations clear, and keep the project moving toward one finished product.
ABOUT HEARTSTONE →Before insulation & drywall
“The wall cavity is the last moment when the house tells you everything.”
A focused close-in review gives the owner one deliberate inspection window to document and challenge concealed work before finishes make correction disruptive and expensive.
