Easily Install a PVC Door with Clear Step-by-Step Pictures

To replace your old door, start by removing it from the hinges. Use a flathead screwdriver to hold the bottom hinge pin at a 45-degree angle. Gently tap the back of the screwdriver with a hammer until the pin comes loose. Repeat this process for the other hinges and carefully lift the door out of its frame. If there wasn't a door in place previously, you can skip this step.

Next, remove the old frame by unscrewing the hinges from the jambs and cutting along the seams with a utility knife. Then, use a pry bar or chisel to pry the frame out and reveal the jambs. Finally, use a nail remover to pull out the nails connecting the frame to the wall and rip the frame out. If your door is hung directly on the jambs without a frame, you can skip this step.

Position the sill at the base of the doorway and ensure it's level. The sill is the base of the door that sits in the frame. Place it between the vertical jambs and align the sides with the center of the door. Check it's level by using a spirit level and adding shims between the sill and the floor if necessary. Nail the shims into place using 1 inch nails. If the sill needs to be cut to size, measure the distance of the opening and mark your cut on the sill before trimming it down with a saw.

Attach the sill to the floor by using a PVC sealant or screws. For concrete floors, use the manufacturer's recommended adhesive to apply a thick bead of sealant across the middle of the sill and press it down. For wooden floors, use 2.5-inch wood screws through the prefabricated slots in the sill. Check the sill's level again before moving on, and if necessary, readjust it. If you used screws, remove them and reposition shims before reinstalling the screws. Remember that the sill will eventually be covered up with trim for your PVC door.

In order to properly install your door, it is essential to ensure a precise fit that prevents air from flowing into your home. To achieve this, start by running a line of silicone caulk along the raised rectangular lip on the sill where the bottom frame of your door will sit. This will effectively seal the gap and prevent air from coming in. Make sure to use caulk that matches the color of your door for a seamless finish.

Next, carefully remove any protective packaging and corner pieces from your door frame using a screwdriver or drill. If there is tape on the panels in the middle of the door, leave it on until the installation is complete. If necessary, attach the handle to your door by sliding it into the prefabricated slots on the front and securing it with screws.

With a friend's assistance, lift the door at a 15-degree angle and slide the bottom of the frame into the slot on the sill, carefully adjusting the door to open in the direction of your choosing. Once in place, ensure that there is a small gap of 0.2-0.3 inches between the new door frame and the jambs to prevent the frame from incurring strain.

It is essential to double-check the final fit of your door before moving on with the installation process. When properly fitted and securely in place, your door will offer a reliable and energy-efficient entrance to your home.

To resize your doorway, consider installing a new jamb if the gap is too big or small. Alternatively, to fill a large gap, you can use larger shims to hold the door in place, though this can increase the chances of the door breaking in the future.

To begin, use shims to secure the frame in the doorway. Obtain 0.5-1 in (1.3-2.5 cm) shims and place one in the middle of the vertical jambs. Slide a symmetrical shim on the opposing side to hold the door frame in place. Repeat the same process for the top and bottom portions of the jambs. Keep checking the gap between the jamb and frame to ensure it remains 0.2-0.3 in (0.51-0.76 cm) as you apply the shims.

The goal is to apply enough shims to secure the door frame whilst maintaining the required gap. Wood shims are flexible enough not to break or bend even under pressure.

Use a mallet to adjust the door's position and make sure it is vertically balanced. Check its position by holding a spirit level vertically against the door. Tap the door gently with a rubber mallet to adjust its position as necessary until it is plumb.

Next, drill assembly screws through the frame to hold it in place. Start with the middle screws and add the bottom screws before adding the top screws, then add the remaining screws. If there are no prefabricated holes, you will need to add at least five screws to each jamb. Place one screw every 6-8 inches (15-20 cm).

Lastly, remove excess shims using a putty knife and mallet. If a portion of the shims is sticking out past the frame or jamb, use the putty knife or a chisel at a 45-degree angle to remove it. Tap the back of the knife or chisel gently with a mallet until the shim snaps off. Repeat this process until all shims exceed the frame.

Ensure a snug fit for the trim by cutting it down to size, unless it is already prefabricated to fit your frame. Jambs come in varying sizes, making it necessary to measure the distance between the jambs for both the top and sides of your frame. Use a grease pencil to mark your cuts and proceed to use a miter saw with a carbide-tip blade to cut your trim. You can also miter the corners by cutting each end at an angle for a perfect fit. If you lack a miter saw, a handsaw will also come in handy, although you may need to fill in the gaps with silicone caulk to adjust any uneven cuts.

Protective gloves, eyewear, and a dust mask should be worn when cutting the PVC. When installing the trim, there should be one set of trim that is shorter to compensate for the top or bottom. Essentially, if the trim at the top spans the entire frame, then the trim on the sides must be long enough to meet the trim at the top, not the jamb. Once you have achieved the desired lengths, you can use either PVC glue or adhesive sealant to install the trim. The manufacturer's instructions should guide you on the required adhesive. Apply a bead of glue or adhesive to the back of your trim and press it onto the doorway where the gap around the frame sits. Hold it in place for around 20 to 30 seconds to set it in place, and repeat the process for the other two pieces of trim.

Complete the installation by running a thin bead of silicone caulk around the trim where it meets the jamb to cover any gaps and keep air out. To achieve an even finish, you can use a caulk gun and smooth it out with your finger or run painter's tape along the trim. Confirm that the door opens and closes correctly by operating it several times before finishing. The installation process requires special equipment, including a screwdriver, rubber mallet, chisel, spirit level, shims, drill, screws, putty knife, PVC adhesive or sealant, miter saw, and silicone caulk.
