Wholesale Windows and Doors for Builders, Developers, and Contractors
RELI offers reliability, pricing transparency, and seamless logistics for builders, developers, and contractors.
Products Available for Purchase
We supply a curated selection of building materials trusted across residential and commercial projects. All items meet high durability, energy efficiency, and design standards.
- Vinyl Windows: Available in double-hung, casement, and sliding styles. These windows are energy-efficient and low-maintenance, ideal for residential builds.
- Aluminum Windows: Sleek, modern frames with strong thermal performance. Ideal for commercial projects or contemporary home designs.
- Fiberglass Doors: Stronger than wood and resistant to warping or corrosion. Excellent for both interior and exterior use in high-moisture climates.
- Pre-Hung Interior and Exterior Doors: Offered in custom sizes to fit any project. These arrive ready to install, saving you labor time on site.
- Patio and Sliding Doors: We carry popular configurations that integrate seamlessly into modern floor plans. Options include dual-pane and low-E glass for improved insulation.
- Hardware and Trim Kits: Match your build with quality handles, locks, and trim sets. All components are designed to meet builder-grade expectations.
Why Quality Materials Matter for Your Business
Material quality directly impacts build performance and long-term client satisfaction. Low-grade products often result in callbacks, warranty claims, or negative referrals. Using trusted components not only improves your end result but also reinforces your professional reputation.

Streamlined and dedicated app to connect you with a qualified contractor because let's be honest, do you really want to find a contractor with the same app you use to find a new lunch spot?
Hours of searching on Google, Yelp, or Angie’s List only to be inundated with calls from contractors, most of which won’t actually show up for your estimate.
Straightforward and transparent purchase process.
Complicated “car buying from hell” sales process full of hidden fees and ridiculous upcharges.

Large upfront deposit. Hopefully, you prayed to the right gods so the guy doesn’t run off with your money.
Instant estimates with no home visit required.
You take time off work to meet the contractor, but they show up two hours late with muddy boots, rush through the job, and miss a key measurement they'll “get next time”—whenever that is.
