  • Trim
  • Stepladder or step stool

Stepladder Vs Step Stool

Very few understand the difference between a stepladder and a step stool. Put simply, a stepladder is a type of ladder with a self-supporting mechanism and it is shaped like an inverted V. 

On the other hand, a step stool looks more like a stool than a ladder. It’s basically a series of steps that leads to a flat platform. 

If you’re carrying out an outdoor project such as this one, I recommend using a stepladder. It’s heavy-duty and sports a rugged design that makes it fit for the outdoors.

For indoor renovations, a lightweight step stool is a better option. If you don’t have a stepladder, a step stool will still work. 

Installing A Patio Enclosure 101

Step 1: Inspection And Measurement

Before you start your enclosure project, it’s a good idea to have your local building inspector go through your plan. Perhaps there are special requirements for how you should enclose a porch such as this and this might require a building permit and inspection. 

Even if it’s not mandatory to have your porch inspected prior to building, it’s a worthwhile investment. It will give you peace of mind knowing that your DIY project doesn’t break any laws. 

Besides, the local inspector might spot problems that need to be fixed on your porch before building the enclosure. 

After the inspection, the next step is to take measurements. To be specific, you’ll want to determine the size of the open sides of your porch, so you can buy an enclosure that will fit in that specific space. Measure both the width and height of the open side or sides of your porch.

For this project, I chose the Generic Waterproof Patio Enclosure  – a sturdy and waterproof enclosure that measures 8 by 10 feet. This is the perfect size for my porch. But, if you have a bigger or smaller porch opening, the enclosure is available in many other sizes. 

Step 2: Build And Install The Frames

If your porch doesn’t have them already, consider installing a couple of frames to hold the enclosure in place. This is not difficult and it only requires basic measuring and woodworking skills. 

Using the measurements you obtained in step 1, divide the length by the number of enclosure sections you want to have. Keep in mind that you don’t want to end up with overly big screen frames. Ideally, they shouldn’t be wider than those for a standard screen door. 

Next, make simple wooden frames from 2x4s. These will be installed between the base of your porch and its roof.  

One tip is to use wood screws as opposed to nails when attaching the frame to the roof. These form a stronger connection and they enhance the stability of the enclosure. 

Step 3: Treat The Wood

If you’re using untreated wood to make the frames, it’s a good idea to treat it. This means painting or staining the wood and it should be done before you install the patio enclosure. 

Start with a good primer, then follow it up with two coats of high-quality outdoor paint. If you opt for staining instead, you can use a paint sprayer to help you stain uniformly across the wood. Remember to cover the floor of your porch with newspapers or tarps to avoid drips and stains. 

Step 4: Install The Patio Enclosure

Given that you measured the wooden frames to size, the Generic Patio Enclosure should fit perfectly when you lay it over the opening. All you’ll need to do is pull the enclosure panels tightly between the frames and secure them in place by stapling.

Alternative Patio Enclosure Option: Using Plastic Sheets

If you don’t like the Generic Patio Enclosure I mentioned above, you can also try enclosing your porch with plastic sheets. This is a fairly cheap alternative. Here’s what you should do:

What You Will Need

Step 1: Measurement

Take measurements of every screen section (the height and width). Then, add 4 inches to these numbers. This will help you to cut the right size of plastic sheet for every section. 

Measure and cut the plastic panel or panels to the correct size, depending on how many screen sections you have.

Step 2: Installation

Place the plastic over the opening. Make sure you position the plastic sheet well, both horizontally and vertically, leaving the excess to cover the area beyond the edge of the framing.

Using a staple gun, connect the top left corner to the frame at about ½ an inch from the inside edge. Do the same to the top right corner. Pull the plastic panel tightly, ensuring that no more than 2 inches of the sheet goes beyond the inside edge of the frame. 

Move to the base of the plastic sheet and pull the plastic sheeting tightly into place. Start by pulling the left side against the opening, making sure that no more than 2 inches of the sheet goes past the interior edge of the frame. 

Again, using your staple gun, staple the lower-left corner. Repeat these steps on the right side of the sheeting.

Step 3: Finishing Touches

If there’s excess plastic on the left side, fold it so that the exterior edge is flush with the interior edge of the frame. Staple the folded section into place. Be sure to add staples to all four edges of the screen.
