Hi, I'm Raúl. Welcome to ProjectCalcWorks.
I'm 26 and I enjoy learning about home renovation, construction and the small decisions that make a project work. I started ProjectCalcWorks because I wanted planning tools that are easy to use, transparent and available to anyone—even if you're tackling your first DIY project.
Why I built this site
It's easy to get lost between measurements, materials, packaging sizes and costs. A calculator should help you understand what to buy and why, not give you a mysterious number you have to trust.
My goal is to make that first planning step simpler: measure your space, see the math, adjust the assumptions and use the result as a starting point for a better conversation with a supplier or contractor.
What you'll find here
- Material calculators for flooring, concrete, paint, roofing and more.
- Cost estimators that let you enter your own local prices and project scope.
- A project budget workspace for combining estimates.
- Practical articles and step-by-step guides to help you prepare.
How I want these tools to earn your trust
Product coverage, waste, packaging sizes and local prices are shown or editable when they can change the result.
Repeatable formulas and unit conversions are tested in code. The methodology explains the approach.
Reference values should be distinguishable from exact math; consult the source register for more detail.
A small example you can verify yourself
Take a 12-by-10-foot room with a three-foot doorway that does not need baseboard. Its gross perimeter is 2 × (12 + 10) = 44 feet; subtracting the doorway leaves 41 feet. Dividing by an eight-foot stock board gives 5.125, so the minimum whole-length purchase is six boards. But that is a quantity estimate, not a promised cut plan: some full wall runs and joints may require an extra board. You can change the assumptions in the Baseboard Trim Materials Planner and see the design limits explained in the accompanying homeowner article.
What I can and cannot verify
ProjectCalcWorks publishes calculator formulas, examples and source references for users to check. Code tests can confirm repeatable math and input handling; they cannot verify the condition of your home, a supplier's current coverage rate, a contractor's bid or local building requirements. The calculation methodology separates deterministic unit conversions from editable assumptions, and the source register identifies the external documents behind product-specific guidance.
The operator is Raúl Gea Diez, not a certified building professional presented under an invented credential. If you find a wrong assumption, broken source or unclear instruction, use the correction and questions channel with the page and input values. Corrections should be based on reproducible evidence, not anonymous testimonials or fabricated jobsite stories.
An important note
I'm sharing planning tools, not claiming to be a licensed contractor, engineer or building inspector. Calculator outputs are estimates, not approved designs or guaranteed prices. Always check the actual product specifications, local requirements and advice from qualified professionals when a project needs it.
