Asking QuestionsAs a vinyl window manufacturer, we have a deep understanding of the parts of a window system and have worked with many home window installers. We also understand that replacing the windows in your home is a significant investment, and hiring the right window installer can be intimidating. So we wanted to provide you with several key questions to ask when you meet with a window specialist. These questions should help you get a more comprehensive understanding of their company, your project and your total cost:

1. How will new windows be better than my current windows?

Any window specialist should be able to clearly tell you about their products’ specific features, and compare those to your current windows. Potential benefits would include:

  • Improvement in energy efficiency
  • Ease of cleaning
  • Reduction of exterior noise
  • Protection from ultraviolet rays
  • Enhancements in safety

2. What window style should I consider for my home?

Exploring all the design options available to you can help you discover some options you might not have otherwise considered. Work with the professionals to choose the perfect window styles to complement your lifestyle. Check out the various window styles available for some ideas.

3. How long have you been in business and how often do you sell windows?

Asking these kinds of questions gives you an idea of a company’s experience and ultimately allows you to choose someone who fits your comfort level. Replacing your home windows can be a big investment, so you want to work with something that has plenty of experience.

4. What is included in my estimate?

It is important to understand what is and is not included in your window estimate so that you do not run into any unpleasant surprises when you receive your final bill. A reputable business should be transparent about the costs that are included in your estimate, as well as what additional outside costs you should take into consideration.

5. Is disposal of my current windows covered in the project’s price?

Some installers leave the disposal of your old windows up to you, while others will haul them away for you. Asking about the disposal of your current windows can ensure that you’re not surprised by any additional costs during or after the project.

6. May I have a list of references and clients you have done similar work for?

If you’re not comfortable taking their word, their past clients might be willing to tell you more. Word-of-mouth is essential in the window replacement business, and a reputable company most likely maintains a list of references and should be more than willing to provide it to you.

NOTE: When speaking to references, consider asking questions regarding cleanliness, punctuality and any unexpected costs.

7. What is the warranty on the replacement windows, and does your company offer additional warranty coverage?

Every home replacement window typically has a warranty from the manufacturer. (Check out our lifetime limited window warranty for reference.) This helps to ensure that you’re covered if something happens to the window product. Though, the manufacturer warranty usually does not cover damage related to the installation.

This is why you will want to ask the business that installs the windows what type of warranty they will provide on the installation.

Often, the window manufacturer will also offer a glass breakage warranty option, if you have ever had a window break before you know the pain that can cause. This added warranty can sometimes be a little extra but if you have a window break it pays for itself!

If the window specialist has not already told you who will be doing the installation, a final question to consider asking is who will be doing the installation. This will help you understand the size of the business and the network of people they use to complete a job.
