How to Accurately Measure Your House for Siding

Properly gauging the area that requires new siding is crucial when considering an exterior update. Siding not only enhances your home’s aesthetic but also acts as a protective barrier against environmental elements. This step-by-step guide from KV construction LLC, based in Everett, WA, will ensure you achieve a precise measurement and make an informed decision about your siding needs.

Step-by-Step Siding Measurement Process

1. Sketching the Measurement Areas:
Start by creating a detailed sketch of your home’s exterior. Break down each side of your house into geometric shapes—primarily rectangles and triangles. This breakdown will make the subsequent steps more manageable and ensure that no area is overlooked.

2. Measuring Rectangles:
For each rectangle in your sketch, measure its height and width. Record these dimensions directly onto your sketch to keep track of your calculations. Multiply the height by the width to determine the area in square feet.

3. Measuring Triangles:
Triangles can be slightly more complex due to their shape. Measure the base of the triangle and halve this figure. Multiply this number by the height of the triangle (from the base to the peak). This calculation gives you the area of each triangular section.

4. Summing Up the Total Area:
Add together the area calculations for all the rectangles and triangles to get a total square footage of the surfaces needing siding.

5. Accounting for Non-Siding Areas:
Measure any sections of the exterior that will not require siding, such as areas covered by doors, windows, or existing materials like brick or stone. Calculate the area for these sections, then subtract this total from your previously calculated siding area to adjust your overall measurement.

Utilizing Technology for Precision

In today’s digital age, technology can simplify the measuring process. For example, smartphone apps like Apple’s Measure app use augmented reality to estimate distances and areas through your device’s camera. These tools are particularly useful for quickly measuring large or inaccessible exterior walls.

Laser Measures for Enhanced Accuracy

For ultimate precision, consider using a laser measuring device. These tools are accurate and can measure long distances by emitting a laser pulse to a target point, then calculating the time for the reflection to return. This method is ideal for large properties or when measuring for high or hard-to-reach areas of your home’s exterior.

Next Steps After Measurement

Once you have your total square footage, decide whether to undertake the siding project yourself or hire professionals. While a DIY approach might save costs, hiring experienced contractors like those at KV construction LLC ensures the job is done efficiently and effectively, often spotting potential issues before they become costly.
