When To Replace Windows

  • Outdated and inefficient window styles that detract from your home’s curb appeal.

How To Choose a Window Company

Hiring an experienced window installer helps ensure good results and a great experience. Below, we outline the main considerations for identifying a qualified window installer.

Experience

Make sure you select an experienced local installer with a long record of successfully installing and replacing windows. Installers that have been operating locally for many years are more likely to understand the local climate and local homeowners' needs. Get references from recent clients to learn more about a provider’s service.

Certifications

Choose companies that have certifications from top window brands, and that have Fenestration and Glazing Industry Alliance (formerly AAMA) certification. Being certified indicates that they've received proper training in installation best practices. Make sure installers are staff, not subcontractors, and confirm that any technicians working on your home are certified.

Reputation

Read through online customer feedback, check the Better Business Bureau (BBB), and ask for local references. Review customer feedback to verify that the company consistently provides quality work and good customer service. Avoid companies that have complaints of shoddy work or unfinished jobs.

Process

The best company will take time to provide you with a comprehensive project plan, timeline, expectations, and reviews of all material and installation options. Beware of vague quotes or timelines that lack clear and specific information. Look for regular communication throughout the process to avoid surprises down the road.

Warranties

Seek out window installers that assure quality installations and offer warranties on labor and materials. This shows confidence in their work. Select companies with unlimited lifetime warranties that can transfer to new homeowners.

Materials

Ensure your provider uses durable, energy-efficient window brands that work with your budget. Look for good energy ratings, design flexibility, and enhanced UV protection. Confirm the window materials have their own manufacturer warranties as well.

Frequently Asked Questions About Window in Sterling, VA

In Sterling, the best time to install windows is when temperatures are mild, generally in the spring or fall. This enables professionals to do their work with less worry about the weather.

The best type of replacement window for your Sterling home will vary based on the age of your home, as well as your personal style and budget. You'll want to consider the style of your home — such as if it's more modern — so your new windows match. Wooden windows can provide a traditional look and feel, while vinyl-framed windows are more popular in newer homes. Fiberglass windows are also a popular choice, as they are energy efficient and long-lasting.

This includes taking out the old windows, taking measurements for the new windows, installing the new windows, and caulking them in place. On average, it takes about 30 minutes to install each window.

In some cases, you can install your own windows, but it's recommended to hire a professional. It's important to consider the local temperature when replacing windows, as it will impact the process. For example, the temperatures in Sterling can reach an average high of 63, so you should think about energy-efficient windows that can protect from the heat. It's also important to get the measurements right and understand the instructions for installation.

Hiring a professional window installer helps make sure the job is done correctly. Professional installers will measure your windows properly to get a perfect fit and will use the right techniques and materials to ensure your windows will be correctly sealed and fitted. Additionally, professional installers are likely to have access to better materials and more knowledge than the average homeowner, so you can count on your windows to be installed correctly and last for years to come.
