Question 1

How do I use RemodelCalc calculators?

Accepted Answer

Each calculator is designed to be simple: (1) Enter your measurements in the input fields, (2) Select material types and preferences, (3) Click "Calculate" to see your results. All calculations include material quantities, costs, and shopping lists. You can save calculations to your project page for easy reference.

Question 2

Do I need to create an account?

Accepted Answer

No! RemodelCalc is completely free and requires no account. All your calculations are saved locally in your browser using IndexedDB, so your data never leaves your device. This means your project information stays private and secure.

Question 3

Can I use RemodelCalc on my phone or tablet?

Accepted Answer

Absolutely! RemodelCalc is fully responsive and works great on mobile devices. The touch-friendly interface makes it perfect for taking measurements on the job site and calculating materials in real-time.

Question 4

What if I don't know my room dimensions?

Accepted Answer

Use a tape measure to measure the length and width of your space. For best accuracy, measure at floor level for flooring projects and at the specific height for wall projects. Always round up to the nearest inch for safety. Our calculators also include measurement guides for each project type.

Question 5

Should I measure in inches or feet?

Accepted Answer

Most of our calculators use inches by default because it provides more precise measurements for material calculations. However, you can change your preferred unit system in the Settings page. The calculator will automatically convert between units.

Question 6

How do I measure an irregularly shaped room?

Accepted Answer

Break the room into rectangular sections and measure each separately. Use the "Detailed Mode" in calculators (like Tile and Flooring) to enter multiple wall measurements. The calculator will automatically sum up the total area for you.

Question 7

How much extra material should I order?

Accepted Answer

We recommend 10-20% waste depending on the project: 10% for straight patterns and simple layouts, 15% for diagonal patterns or moderate complexity, and 20% for herringbone patterns or rooms with many corners and obstacles. Always order extra for future repairs, as materials can be discontinued.

Question 8

Why do waste percentages vary by pattern?

Accepted Answer

Complex patterns like diagonal and herringbone require more cuts at edges and corners, resulting in more unusable pieces. Straight patterns waste less material because cuts are simpler and offcuts can often be used elsewhere.

Question 9

Can I adjust material prices in the calculator?

Accepted Answer

Yes! Visit the Settings page to set custom default prices for materials like tile, lumber, concrete, and more. These prices will be saved in your browser and used for all future calculations. This helps you get accurate cost estimates based on your local supplier prices.

Question 10

How do I save my calculations?

Accepted Answer

Click the "Save to Project" button in the results section of any calculator. Your calculation will be saved to your Project page, where you can view all saved calculations, export to PDF/CSV, and print shopping lists.

Question 11

Can I share my calculations with others?

Accepted Answer

Yes! Click the "Share" button to copy a URL that includes all your calculation inputs. Anyone with the link can view and modify the calculation. This is perfect for discussing projects with contractors or family members.

Question 12

Where is my calculation data stored?

Accepted Answer

All calculation data is stored locally in your browser using IndexedDB. Nothing is sent to our servers. This means your data is completely private and only accessible from the browser and device you used. Clear your browser data will delete your calculations.

Question 13

How do I export my project shopping list?

Accepted Answer

Visit the Project page and click the "Export CSV" button to download a spreadsheet, "Export to PDF" for a printable summary, or "Print List" to print directly from your browser. All exports include itemized materials with quantities and costs.

Question 14

What size grout line should I use for tiles?

Accepted Answer

Use 1/16" (0.0625") for rectified tiles with very straight edges, 1/8" (0.125") for most ceramic and porcelain tiles, and 1/4" (0.25") for natural stone or rustic tiles. Larger grout lines allow for tile size variations and are easier for DIY installation.

Question 15

Do I need to seal my tiles?

Accepted Answer

Glazed ceramic and porcelain tiles don't need sealing. Natural stone (marble, travertine, slate) and unglazed tiles MUST be sealed to prevent staining. Always seal grout lines regardless of tile type to prevent moisture penetration and discoloration.

Question 16

What's the difference between laminate, LVP, and hardwood?

Accepted Answer

Laminate is the most affordable, water-resistant, and durable for high-traffic areas. LVP (Luxury Vinyl Plank) is waterproof and great for basements and bathrooms. Hardwood is the most premium option but requires maintenance and isn't suitable for wet areas.

Question 17

How do I know what lumber grade to buy?

Accepted Answer

For structural framing (joists, beams), use #2 grade or better pressure-treated lumber. For visible decking surfaces, use #1 grade or premium grades for fewer knots and better appearance. Check local building codes for specific requirements.

Question 18

How long does concrete take to cure?

Accepted Answer

Concrete reaches walking strength in 24-48 hours, but full cure takes 28 days. Wait at least 7 days before heavy use. Keep concrete moist during the first week for proper curing (cover with plastic or wet burlap). Temperature affects cure time—warmer weather cures faster.

Question 19

Why aren't my calculations saving?

Accepted Answer

Check that your browser allows localStorage and IndexedDB. Private/Incognito mode may prevent data storage. Some browser extensions can block storage as well. Try disabling extensions or using a different browser. If issues persist, your browser storage may be full.

Question 20

The calculator results seem incorrect. What should I check?

Accepted Answer

Verify your input units match what the calculator expects (inches vs feet). Check that all required fields are filled in. Make sure waste percentage is reasonable (10-20%). If results still seem wrong, try resetting the calculator and re-entering your values.
