How to Start a Window Installation Business – A 2024 Guide

An increasing number of homeowners understand that they’re losing warm or cool air because of their old windows. Hence, in most cases, they choose to replace the old ones with new, energy-efficient windows that’ll lower their cooling and heating expenses, but more importantly, ones that’ll increase the security of their homes. If you’re thinking about starting a window installation business, you should know that it’s quite lucrative, but you should also know that you’ll have to go through the following steps:

1. You Need to Get Trained + Obtain a License


The first step you’ll have to take is to get trained properly. You could do this by applying to the “Installation Masters” or the “National Glass Association” programs. After you go through the training, you’ll have to get in touch with your local building department in order to learn what type of license you’ll require. Depending on the state you reside in, they’ll instruct you on what you’ll have to obtain.

2. Purchase a Vehicle + The Tools & Equipment You’ll Need

Once you get trained and obtain the license you’ll need, you should purchase a commercial vehicle that’ll help you transport all of the tools, equipment, and materials you’ll require for a specific job. Additionally, don’t forget that you’ll need tools and equipment that’ll enable you to do the job.

For instance, if you opt for purchasing a glazing robot, it’ll do wonders for you, mostly because you could use it to lift, transport, and install big and heavy windows. Keep in mind, there are various models on the market, hence, before you purchase the first one that comes up in your search but, learn more about the models you could get.

3. Get Insured!


If there is one thing that you should take away from this article, it’s the fact that you must get insured. Why is this important? Well, if there is ever a situation where you cannot complete a specific job, your clients will be covered. You can obtain insurance through your insurance provider.

4. Find an Experienced And Reputable Supplier

You should opt for working with a supplier that is experienced and reputable, but more importantly, you must work with someone that offers a wide range of windows including fiberglass, double-pane, wood clad, vinyl, and so on. Don’t forget, you’ll want to obtain a few samples first, mostly because you can create a portfolio that you’ll show to your future clients.

5. Marketing Your Business is The Key


You won’t be able to succeed if you don’t create a marketing strategy for your business. Besides printing posters, door hangers, and fliers, you should also develop a website for your business, where you’ll display all the necessary information your clients might want to see before they hire you.

6. Don’t Forget The Contracts!

Last on our list, but equally as important as everything else we mentioned is the fact that you’ll want to develop contracts that’ll include the job that has to be done, the guarantees you offer, as well as the duration, installation practices, and the costs of a job. This will surely make your business look more professional.


If you’re thinking about opening a window installation business, you should definitely follow all the steps we mentioned in our list above. By doing so, you’ll make the entire process easier and less daunting, but more importantly, you’ll be able to ensure that you’re doing everything in the right way – which is something that can ensure success.
