What is Picture Window?
A picture window is a stationary piece of glass–it does not open or shut. Its only function is to provide an open view of the outside, with lots of natural light. Since they have no moving components such as hinges or sashes, picture windows are quite energy-efficient since there are fewer places where air can pass out or in, though with insulating glass.
They are available in all sizes and shapes and are also paired with other forms of windows that do open, such as casement or awning windows, to offer both light and ventilation in a room.
Prepare Before Installing Picture Window
But before you can even consider picking up a hammer, there’s some foundation work that needs to be done.
Tools & Materials You’ll Need
- First, let’s get your tools together.
- Tape measure, level, and a notepad
- Caulk, screws, drill, shims, hammar, pry bar, and utility knife.
- Your new window, plus flashing.
- Safety equipment: gloves and goggles.
- An assistant, particularly for larger windows, an additional pair of hands can be greatly beneficial and safer.
Permits & Regulations
Check local building regulations and codes before beginning the installation. Certain regions ask for permits for window installations, particularly if they involve structural modifications. Also, notify your HOA of the work if you do have one.
Nevertheless, It’s always better to err on the safer side than to have a problem with the authorities or potentially have to take out the window you installed.
Removing the Old Picture Window (if replacing)
If you want to replace an old window with a new picture window, here’s how to do the removal:
- Remove curtains, blinds, or furniture near the window and place drop cloths on the floor to catch any debris.
- Carefully pry the inside trim loose with your pry bar, then score along the edges with your utility knife to cut through the caulk or sealant.
- Take out screws or nails securing the old window.
- If it’s a sash window, you should be able to take out the sashes first. Then pry out the frame from the opening.
- Clear any debris, old nails, or shattered glass.
Additional considerations: Wear gloves to protect your hands from sharp edges. If you suspect the old window contains lead paint (common in older homes), take extra precautions like wearing a respirator and properly disposing of the debris.
How to Install a Picture Window: A Step-by-Step Guide
Below are detailed instructions on how to install a picture window; seek assistance if you are dealing with a big window.
1- Prepare the Rough Opening
Begin with a check for any rot or damage to the framing and repair or replace the sections as needed.
- Use a level and measuring tape to make sure the sill (the bottom part of the opening) is plumb (straight vertically), level (straight horizontally), and square. This will ensure the window fits correctly and functions properly.
- Apply self-adhesive flashing tape along the sill and sides to keep water out. Or add a sill pan that channels any water that may enter back outside, safeguarding your home’s structure.
2- Dry-Fit the Window
Carefully set the window into the opening to check it fits without pressure. The slight gap between the window frame and the wall is normal and essential for adjustments.
- However, if the window doesn’t fit correctly or the gap is wider than ¼ inch, you’ll likely need to add shims (explained later).
- Pre-drill pilot holes into the window frame and the framing of the rough opening with your drill and screwdriver bit. This is done to guide the screws in easily and avoid splitting the wood after fixing the window.
Follow the manufacturer’s directions regarding the recommended location and type of screws.
3- Secure the Window
Run a bead of high-quality exterior-grade sealant along the backside of the window’s nailing flange or perimeter where it will meet the house wrap.
- Gently place the window into the opening, pushing it firmly against the sealant.
- Add shims as necessary to hold the window level and plumb in the opening; don’t over-tighten.
- Now, drive your construction screws into the pre-drilled holes and tighten them up, starting with the top corners, working down.
- Keep checking your level as you work to ensure that the frame is still square and level as you are tightening it.
4- Insulate & Seal
- Fill the gap between the window frame and the rough opening with low-expanding spray foam insulation. Be super careful to not apply too much, it can distort the window frame.
- Alternatively, you can use fiberglass insulation, packing it in snugly without compressing it too much.
- Wrap the nailing flange with self-stick flashing tape, beginning from the bottom, sides, and ending with the top, for a watertight seal.
- Apply a bead of water-repellent caulk around the outside edge at which the window is butting against the siding to seal the area. Flatten it out using a wet finger or caulking tool to have a clean finish.
5- Installing Interior Trim & Finishing
- Put back the interior trim or molding that you took out. If the original trim is compromised or you are using a new window, measure and cut new trim pieces to fit along the window.
- Either use a nail gun or a hammer and nail set for a neat finish.
- Finally, plug any nail holes using wood filler and sand them smooth once they have hardened. You can also prime and paint the trim to your color of choice.

Inspection and Troubleshooting Common Issues With Picture Windows
Congratulations, your new picture window is in! But before you stand there gazing at the view for too long, take a moment to correct any hiccups.
- Look for gaps or drafts around the window frame, both in and out. If you notice any air, you may need to add additional insulation or caulk.
- Ensure the window is level and plumb. If it appears crooked, it may be a problem with the original framing or shimming. Back out screws, realign shims, and re-tighten. If the frame is warped, call the manufacturer—it may be faulty.
- Look for any water leak signs, especially after rain. Inspect the interior and exterior seals. If you see any moisture, reapply exterior caulk or replace flashing.
If you feel anything is too big for your comfort in handling it, do not think twice in availing a professional window installer’s services. Better done once than with possible subsequent complications.
