What you need to know about San Antonio window replacements
Replacing your windows can be scary, we know. Before getting started on your project, there are a few things you probably want to know about window replacements like how much it costs, how long the installation process will take, and what replacement windows are made of.
How much does a window replacement cost?
The cost to replace one 3 ft. x 5 ft. window can range anywhere from $300-3,000 depending on the window and installation type. If you are looking to replace your window yourself, you can find replacement windows at a local hardware store for less than $300. However, a professional window replacement will range more in the thousands to replace one standard s ft. x 5 ft. window. The cost of your window replacement project will depend on the window type, size, quality of the window, quality of the installation, and warranty.
Why is there such a wide range of pricing?
The range of cost for replacement windows all comes down to quality. A low-quality window is going to be low-cost just as a high-quality window is going to be a higher cost.
Less expensive windows typically also have a lower lifespan. When you pay for a higher quality window, you’re paying for it to last.
How long will it take to install my new windows?
Generally, one installation crew can install 10-15 windows in one day. However, this depends on the size of the windows and the degree of difficulty of the window. For example, a window on a second or third story of a home will take longer to replace than a window on a first floor.
How do I choose the right window for me?
When shopping for replacement windows, you must consider your budget, goals, wants, and needs for your project. Asking yourself the right questions, like how energy efficient you want your windows to be, how long you want them to last, and how durable you want them to be, is crucial to finding the right window for you. Our expert design consultants can help guide you to the right window type and style.
Can you repair my existing window?
If you are having troubles with a window that we previously installed, we will service that window to repair or replace it if need be. However, Southwest Exteriors does not perform general window repairs, including glass repairs.
