Frequently asked questions about window companies

Window replacement isn’t complicated, so a beginner can do it provided they follow the instructions. Whether you’re doing your own home window replacement or hiring a pro, it’s an inexpensive project that’ll run you roughly $100 to $250.

You may want to consider replacing your windows if there is visible damage to them, a draft is coming through, or condensation is forming on the inside of the window.

Here’s how you do a home window replacement:

  1. Remove and set aside the inside stop.
  2. Remove the lower window sash, the parting stop, and the top sash.
  3. Remove all materials associated with the sash.
  4. Stuff the sash pockets with insulation.
  5. Fit the replacement window in place and put mounting screws in at the sides.
  6. Apply caulking around the outside edge of the window.
  7. Put the old inside stop back in its spot.
  8. Install your trim, and then apply caulk to seal up the top and bottom of the window.

While installing a window replacement is a simple procedure, you may wish to hire a contractor anyway.

Most people are familiar with the more common window types, such as the bay window or the slider window. There are over 15 different types of household windows, but listed below are the 10 most common window types for the home.

  1. Bay. Bay windows are designed to stick out rather than being flush with the wall. They form a recessed area inside, which can be used as a seat or a shelf.
  2. Slider. A slider window is designed with side-by-side panes, which open or close by sliding on a track.
  3. Casement. Casement windows feature window panes that open outward from a side axle. Like awning windows, they open and close with a crank or lever.
  4. Egress. Egress windows are mainly functional in that they offer a potential exit route from a room in case of fire or other emergencies. Basements are often fitted with egress windows.
  5. Single hung. A single hung window opens and closes vertically, using only one window sash.
  6. Double hung. Double hung windows are identical to single hung windows, except they use two sashes.
  7. Picture. Picture windows do not open. Instead, they feature large window panes that allow you to have a mostly unobstructed view.
  8. Awning. Awning windows open outward, usually with a small crank handle or a lever, forming an awning that is designed to allow airflow while keeping rain out.
  9. Glass block. Built entirely of glass blocks, this kind of window allows natural light in while maintaining your privacy.
  10. Arched. Arched windows have a rounded top that adds architectural flair to your home, but they’re not designed to open.

The cost of a home window replacement depends on a few different factors. The average cost is around $300 per window, without considering the cost of labor or other materials. The actual price range is between $230 and $370 per window, while the cost of labor and extra materials is between $430 and $680.

Here’s a list of some of the biggest factors affecting the price of your window replacement:

  • Window type. Single hung windows have a price range of $100 to $400, while bay windows have a range of $500 to $2,500.
  • Energy efficiency. Energy-efficient windows can cost from $120 to $1,200, with a further $200 to $800 per window in labor costs.
  • Type of material. Windows can have aluminum, vinyl, wood, or composite frames. Aluminum windows will cost you around $130 for a double hung window of average size, while a composite window of the same dimensions will cost you around $1,300.
  • Contractor vs. DIY. Installing a replacement window on your own means only paying for the window and any materials. Hiring a contractor will add the cost of labor onto the price of your window replacement.
  • Location. The room you’re installing a window in can impact the cost of the window. For example, living room windows are typically larger than those in any other room, so they’ll cost more.

A window screen allows you the benefit of airflow without all the flying bugs and debris that can come with it. Unfortunately, window screens can get damaged. When that happens, they can’t do the job they are intended to do. Fortunately, replacing a damaged window screen is not difficult.

Here’s how you can replace your own:

  1. Open the window completely so that the entire screen is accessible.
  2. Pull the bottom lift tabs upward to release the bottom of the screen from the window.
  3. Gently pull the top part of the screen down and out of the window.
  4. Place the top part of the new screen into the screen track at the top of the window.
  5. Using the bottom lift tabs, guide the screen into the bottom screen track.
  6. Once the screen is in place, let go of the lift tabs and allow the screen to settle into place.
  7. Make sure there are no gaps around the outside of the screen.

When choosing a home window replacement, you’ll need to do your due diligence and research different brands, types, and materials. Conducting brand research is fortunately an easy task, but it does require time.

Here’s how you can research the different brands of windows:

Start by determining the kind of window you need. Then, go online and search for “best replacement windows.” Your search results will provide you with a selection of brands and articles detailing the pros and cons of the top brands. From that selection, write down at least five brands that offer the type of window you need, and jot down the pros and cons of each.

Write down the price points for each replacement window brand, including any other relevant facts like where to buy them offline. Make sure to read customer reviews. The pros and cons will give you the basic facts of a brand, but customer reviews will let you know how well the brands perform in real situations.

It’s also useful to consider the customer service offered by any brand. If your replacement window happens to break or has some kind of manufacturer defect, you’ll need to know that the company will provide good customer service and address the problem in a positive way.

Knowledge is key in any renovation, and window maintenance is no different. Before you set about your home window replacement project, there are some things you should know.

Is condensation a problem with my windows? One of the first signs that a window is starting to fail is the accumulation of moisture on the inside of the window or between the panes. If not addressed , moisture in your window can translate into a growth of mildew or mold. Before you pull out your old window, ensure the moisture can’t be attributed to something else, like high temperatures or poor ventilation when cooking.

What is a window’s life expectancy? A well-maintained window will usually last from 20 to 50 years, depending on the type of window.

When replacing windows, should you replace them all at once? If your windows aren’t all damaged, then you should not feel pressured to replace them all unless you want to. Other than providing a unified look, there’s no practical reason to replace all the windows in your home in one project.

How do you choose windows for your home? Home window replacement can seem confusing, but you need to consider the type of window, the framing material, and your budget. The window you choose should meet all your criteria.

On the outside, single hung and double hung windows look basically the same. The difference is in how they function: a single hung window uses only one sash, and only the bottom part of the window opens. A double hung window features two sashes, and both the top and bottom parts of the window can be opened. Both types offer a quality window replacement option, even though they function a bit differently.

Here’s a quick look at the pros and cons of each type to help you decide:

Single Hung Windows – This window type is often the most affordable. It's customizable and needs little maintenance, making it great for smaller rooms. However, they offer limited ventilation and can be challenging to clean.

Double Hung Windows – While not as affordable as single hung windows, double they're affordable enough to meet many budgets. They offer increased ventilation due to their double sash design, are customizable, and easy to clean. Yet, they offer minimal energy efficiency, can be difficult to open if not installed properly, and need frequent dusting on the bottom sill.
