As a contractor or builder, your reputation depends on every detail of your project—from framing and finish work to the quality of the windows and doors you install. Choosing the right window supplier isn’t just about price—it's about finding a reliable partner who delivers quality customer service, has product knowledge, and understands the pressures you face on the job site.
Here’s what you should look for when selecting a window supplier for your next project:
1. Product Quality and Variety
Not all windows are created equal. Look for a supplier that offers:
Durability: Products should meet or exceed building codes and offer long-term performance.
Energy Efficiency: With codes and client expectations evolving, ENERGY STAR® rated windows with low U-values and high solar heat gain coefficients are a must.
Design Options: You need flexibility—various styles, materials (vinyl, wood, aluminum, fiberglass), and custom sizes to fit every job.
Ask your supplier about their manufacturing process and certifications to ensure their windows meet your project’s specs. We at Advanced Window & Door Solutions have a close partnership with our manufacturers and have even brought many of our contractors to the manufacturing facilities to learn more about their products and the process behind building those.
2. Availability and Lead Times
In construction, timing is everything. Long lead times or unpredictable delivery schedules can push back a build and increase costs. A good window supplier should:
Provide realistic and consistent lead times
Offer in-stock options for quick-turn projects
Communicate proactively about any delays or supply chain issues
A supplier with strong logistics and a commitment to inventory management will help keep your projects on track. We have a quarterly newsletter that goes out to anyone that wishes to receive it, that provides product updates of pricing and availability ahead of time if that information is given to us. We also are very active in keeping our customers informed about lead time and delivery changes when they arise.
3. Support and Expertise
You need more than a product—you need a partner. The right supplier should be ready to:
Answer technical questions quickly
Help navigate code requirements and product specs
Offer jobsite support or rep consultations when needed
Whether it’s a custom multi-unit project or a single replacement, responsive support makes your life easier and ensures your install goes smoothly. We pride ourselves on being "A RESOURCE FOR BUILDING PROFESSIONALS" because we offer that support and expertise.
As a resource we offer service when there may be issues that arise that you as the installer may not always be able to take on. If it is beyond our scope of work, we will reach out to our manufacturers about offering their services as well.
We also provide marketing help. We are happy to share, create and help support our partners in with digital, print and in person marketing as well. We often like to feature our partners jobs in our quarterly newsletter and on our social media pages.
4. Competitive Pricing—and Value
Yes, price matters. But remember value is about cost vs. benefit. Low-cost products that fail in the field or delay your timeline can end up costing more.
Look for transparent, competitive pricing
Don’t forget to factor in warranty coverage and long-term reliability
A supplier who can offer cost-effective solutions without compromising on quality will help protect your bottom line.
5. Reputation and Reliability
Finally, do your homework. Ask other builders who they trust. A reputable supplier should have:
Long-term contractor relationships
A track record of on-time delivery and service
Clear communication and accountability when issues arise
Membership and partnership affiliations. Most industry groups that require memberships will not accept companies that are not experts in their field. We are long time members of Nari Milwaukee and Nari National, Metropolitan Builders Association & The Wisconsin Builders Association.
When you find a supplier who consistently delivers, you gain more than materials—you gain peace of mind.
In Summary: The right window supplier should offer more than just product—they should offer partnership.
