Creating a New Window Opening to an Existing Wall: What You Want to Know

Adding new window opening

Does your house feel small and dark? Does your room seem to need something, but you are not sure what that something is?

Do you sometimes wish your windows were bigger? Did you ever wish you could move a window from one place to another for convenience?

Today’s post is all about the cost and everything that factors into creating a new window opening in an existing wall. What I’m going to cover should also apply to moving a window or enlarging your windows.

How Expensive is Adding a New Window Opening?

Most people get critical of the idea of putting holes in their walls. Mostly, because they assume it will be too expensive.

There’s also the annoyance factor: how long will the hole stay there, and how long will the outdoors be coming in?

Others may worry that a bigger window or a new window will be a more significant drain on their HVAC system and consequently create more energy bills.

New window openings are not necessarily expensive or inefficient. It all depends on how well the job is done and what’s inside and on the outside of your walls.

What Goes Into Making a New Window Opening?

Any time you want to put in a new window, you should definitely consult with a licensed contractor.

We never recommend busting into walls by yourself. You never know what kind of ductwork, plumbing, or electricity is running behind that drywall.

A licensed contractor can tell you where these things are located, and if your wall is a good candidate for a new window opening. Of course, if you just want to enlarge existing windows, it’s more likely the plan will work.

Depending on the size of the window you want to install, your wall may need to be fortified with a larger header. The header on a window helps to support the frame of the house over that gaping hole you just made in your home. Your contractor can talk you through all of your options.

Next, the siding in that area has to be removed. Your contractor will cut through the sheetrock and sheathing and then frame the new window opening with studs.

Here’s obviously where it gets tricky with moving things in the interior of your wall and repair around the opening once it’s finished. A general breakdown of costs includes:

  • Rerouting electrical generally costs between $150 and $500.
  • Framing is usually $1,000 to $2,500.
  • Insulation can cost between $450 and $3,000.
  • Trim repair runs in a range from $300 to $1,000.
  • Siding repair pricing runs $300 to $1,100, and that’s if you can find siding to match. It’s a much bigger job if you end up having to replace all of your siding. This cost includes flashing.
  • Drywall installation generally costs $1.50 per square foot.

Once the window is in place, it has to be shimmed, trimmed, and sealed to make sure it does not leak.

Bringing it Home

Adding bigger windows or more windows can dramatically change the appearance and character of the inside and outside of your house. Plus, it’s much more cost-effective than building an addition onto your home.
