Measuring and Marking the Gutter

Although you may think that cutting gutters is a fairly easy and straightforward task, there is actually a bit of a process that goes into it. The first step is measuring and marking the gutter. This will ensure that you get a clean and straight cut.

Measure the length of the gutter

No matter what system you’re using, you’ll need to know how long your gutter is going to be. Use a tape measure to determine the length of the gutter, starting at one end and measuring to the other.

Mark this measurement on a piece of paper or directly onto the gutters themselves with a permanent marker so you’ll know where to make your cuts. You can also use a chalk line or paint to mark a line on the gutters, but be sure to use something that will wash off easily so it doesn’t affect the final product.

Mark the gutter at the desired cut point

You’ll need a measuring tape, a level, and a pencil. Measure up from the bottom of the gutter at the desired cut point and make a mark. Extend your level across the gutter and draw a chalk line at the mark. This will give you a cutting guide that is level, which is important for making sure your gutters function correctly.

Cutting the Gutter

To ensure a proper fit, you’ll need to cut your gutters. You can use a handsaw, circular saw, or jigsaw, but for the cleanest cut, use a power miter saw. If you’re using a power miter saw, you’ll need to make a few adjustments before you start cutting.

Place the gutter on a stable surface

Start by setting the gutter on a couple of sawhorses or a table saw sled. This will ensure that the gutter is stable and won’t move around while you’re cutting it. If you’re using a power saw, make sure that the blade is sharp and in good condition. A dull or damaged blade will make it harder to get a clean, straight cut.

Next, measure the length of the gutter and mark it with a pencil. It’s important to be as accurate as possible when measuring and cutting gutters because even a small error can cause problems later on. For example, if you cut the gutter too short, you won’t be able to connect it to the downspout. If you cut it too long, you’ll have to trim off the excess later.

Once you’ve marked the cutting line, set up your saw so that the blade is just touching the line. If you’re using a power saw, make sure that the blade guard is in place and that your hands are well away from the blade. When you’re ready, slowly start cutting along the line.

If you’re using a manual saw, it’s important to apply steady pressure so that the blade doesn’t wander off course. Keep your hands well away from the blade and stop periodically to check your progress. It’s also a good idea to wear gloves when cutting gutters because the sharp edges can be dangerous.

When you reach the end of the cut, be careful not to overshoot or you may damage the gutter. If necessary, use a file or sandpaper to smooth off any rough edges before moving on to the next piece.

Cut the gutter using a hacksaw

If you’re installing a new gutter or fixing an old one, you’ll need to cut it to the correct length. You can use a hacksaw, recip saw or circular saw to cut gutters, but a hacksaw will give you the most control over the cut.

Here’s how to do it:

1. Measure the length of the gutter you need and mark it with a pencil. If you’re cutting an existing gutter, measure from the end cap or outlet.

2. Place the gutter on a sawhorse or other stable surface. If you’re cutting an existing gutter, support it so that the section you’re cutting is hanging freely.

3. Use a hacksaw to cut through the gutter at your mark. If you’re cutting an existing gutter, be sure not to damage the adjacent section of gutter.

4. Repeat steps 1-3 until you have all the gutters you need for your project.

Finishing the Cut

Applying a clean, straight cut to a section of gutter is essential for a proper installation. Many professionals use a power miter saw to make the cut, but a standard handsaw will work just as well. Be sure to use a sharp blade and to make a light pencil mark on the gutter where you want the cut to be. This will help you keep the blade in a straight line as you cut.

Smooth out the cut edge with a file

Whether you’re doing a basic repair or starting from scratch, you want the cut to be as clean and straight as possible. Use a file to remove any sharp burrs or irregularities along the cut edge. A few swipes with a medium-grit file should do the trick.

Test the fit of the gutter

Once you have your gutter sections cut to length, it’s time to test the fit. Lay the gutter upside down on a pair of saw horses and set the downspout in place. If you’re using “L” or “U” shaped hangers, now is the time to install them.

With a partner holding the gutter in place, use a level to check that the gutter is sloped correctly. The minimum slope for gutters is ¼ inch for every 10 feet of run. This allows rainwater to flow towards the downspout.

Check that the hangers are spaced evenly and at the correct intervals. For K style gutters, hangers should be installed every 24 inches. For half-round gutters, hangers should be installed every 36 inches.
