What broad criteria make a good window and door contractor?

Here are general key qualities that you should expect when looking at a good window and door contractor.

1. Top-Tier Customer Satisfaction: Treating their customers well can be evident in continuous Google reviews that speak on their reputation and quality of service. Customers who do repeat business with them, and refer family and friends to the business are also a good indication that they have a high rate of customer satisfaction. 
2. Dedication to High-Quality Installation: Contractors that follow industry best practices and do their highest quality of work for every job. This can be seen through continuous industry training and asking to see real-life examples of their work similar to the scope of your project. 
3. Post-Installation Care: Your relationship doesn’t end after your products are installed. Contractors should provide meaningful warranties on your products and services. This can include a great reputation for handling repairs on your investment and being upfront about what their warranty exclusions are. 

What criteria did we consider when choosing the top window and door companies in Pittsburgh?

We encourage homeowners to research each window and door contractor that they are considering and weigh the criteria that are most important to them when working with a company. 

This is the process we used when making this list. For us to decide who are the best window and door companies in the Pittsburgh area, here are the criteria we used:

• Ratings, Reviews, and Recognition: A continuous stream of positive reviews across many platforms shows consistency in their work and high levels of customer satisfaction. Relying on customer feedback is a great way to learn how a company treats their customers. We used Google for rating and review information. 
• The BBB Torch Awards for Ethics recognizes local organizations for their strong ethical values and dedication to character, culture, customers, and community. This emphasizes a business's commitment to doing the right things by their customers, employees and community. The recipient is selected by ethics professors at Duquesne University Business School. Once recognized, a company is not eligible to be considered again for four years.
• High-Quality Installation: Having a general contractor license does not mean the business is held to the highest standard for the installation of its products. We focus on having ProVia trained installers, as this brand is one of the country’s top window and door manufacturers. This means the installers have completed specialized training for installing ProVia products in a professional-class manner.
• Subcontractors or Employee Installers: Installation is just as important as the product. Some contractors use their own employee, full-time installation teams while others hire outside installers to do the work. Companies that have in-house, employee installers can more easily guarantee consistency and quality, while subcontracted employees get paid by the window or door and may sacrifice quality for speed.
• In-House Manufacturing: When a company manufactures its own products, it allows them to hold high standards for quality control and manufacturer's warranty. This also makes them an expert in their product lines and services. 
• Showroom to Test Products: It isn’t often you would make such a large investment without seeing and operating the product first. You wouldn’t buy a car without driving it first… why should windows and doors be any different? It is important to be able to fully evaluate the products before you invest in them. As for bonus points, having a brick-and-mortar location is also a testament to the longevity of a company. 
• Warranty Coverage for Installation: One of the most confusing issues in the replacement window and door industry is what the warranty covers and for how long. Does the company have a follow-up service team to keep the product in optimal condition when something goes wrong? How long is this service available to the homeowner after installation and what are the limitations involved? It’s important to understand the value of your investment aside from the cost of the product.
• Locally Owned and Operated: Supporting a local business often means more personalized service, quicker response times, and a deeper understanding of Pittsburgh homes, climate, and seasonal challenges. While larger, national companies may offer broader resources or extended product availability, locally owned companies often have stronger ties to the community and a vested interest in maintaining their reputation through exceptional service.
