Our Renovation Process & Estimates

At McCarty Squared Inc., we believe that a successful renovation begins with a clear, structured process and transparent estimating. Whether you’re planning a full home renovation, accessibility upgrade, or custom project, our team works closely with you to define scope, budget, and expectations from the outset. Our approach is collaborative and detail-oriented, ensuring that every phase, from concept development to final construction, is carefully planned and executed. We provide different levels of estimates depending on how defined your project is, helping you make informed decisions as your vision evolves.

By combining industry expertise with a client-focused process, we minimize surprises, maximize value, and deliver results that align with your goals, timeline, and budget.

A Full-Service Approach from Start to Finish

McCarty Squared Inc. supports clients through every stage of their renovation journey.

What Our Process Includes

We don't just build; we manage the entire journey. Our team remains deeply engaged at every milestone to ensure the final result aligns perfectly with your vision.


  • Discovery: Initial consultation and collaborative idea development.
  • Definition: Design planning, scope refinement, and detailed estimating.
  • Compliance: Managing permit applications and local approvals.
  • Execution: Professional construction and dedicated project management.
  • Completion: Final walkthrough and formal project closeout.

Renovation Estimate Tiers


Understanding the "why" behind the numbers is crucial. We offer two tiers of estimating to match the current stage of your planning.

Class C: Preliminary Budget / Free Estimate

Ideal for the early planning stages when details are still fluid. This helps determine if a project is feasible before investing in deep design work.


  • Basis: Approximate measurements and typical labor/material averages.
  • Purpose: Establishes a general budget range and project direction.
  • Accuracy: Typically within 20–30% of final costs.


Class A: Detailed Project Estimate

This is a high-precision document prepared once layouts, materials, and finishes are finalized.


  • Basis: Precise measurements, finalized plans, and specific material selections.
  • Purpose: Used for final contracts and construction scheduling.
  • Accuracy: Typically within 5–10% of final costs.

Financial Safeguards & Contingency

Renovations—especially in older homes—can reveal hidden surprises. To ensure your project doesn't stall, we recommend a 15% reserve fund. This contingency accounts for unforeseen site conditions and ensures a smooth, uninterrupted path to completion.

Timelines & Communication

Efficiency and accuracy drive our schedule. We value your time and aim for the following responsiveness benchmarks:


  • Site Meetings: Generally scheduled within two weeks of initial contact.
  • Estimate Delivery: Within 10 business days for large projects (faster for smaller scopes).
  • Evolution: Constant refinement of scope as your project details move from concept to reality.

Strategic Planning & Specialized Support

We believe the most successful builds happen when the heavy lifting is done upfront. We invest significant time in Project Development to prevent costly mid-construction changes.


  • Accessibility Projects: For projects focused on specialized accessibility needs, we provide expert assessments for a $225 site visit fee, ensuring your space is both functional and compliant.
