Duncan Glass & Mirror in Oklahoma City: Custom and Residential Window Installation

Duncan Glass & Mirror is a full-service glass fabrication and installation shop located in Oklahoma City that handles residential windows alongside mirror work, shower enclosures, and storefront glass. The business operates as a made-to-order operation rather than a retail showroom, meaning customers work directly with the shop to specify materials, dimensions, and installation details for each project.

What Duncan Glass & Mirror Actually Does

Duncan Glass & Mirror fabricates and installs custom windows for homes across the Oklahoma City metro. The shop handles both replacement windows in existing frames and new construction installs. Beyond windows, the business cuts and installs mirrors, tempered glass for shower doors, glass table tops, and commercial storefront glazing. Projects range from a single replacement window to whole-home window packages. The shop does not stock pre-made windows off a shelf; every window is built to order based on customer specifications and site measurements.

Window Types, Materials, and Pricing

The shop works with standard residential window frames including vinyl, aluminum, and wood options. Single-hung, double-hung, casement, sliding, and fixed-frame configurations are available. Tempered and insulated glass packages are standard for residential work.

Pricing for residential window installation typically runs between $300 and $800 per window depending on size, frame material, and glass type, though larger or specialty windows cost more. A three-window replacement project for an average home generally falls in the $1,500 to $3,000 range before labor. Exact quotes require an in-home or site measurement; the shop does not publish fixed rates online. Call ahead to request a free estimate.

How Duncan Glass & Mirror Compares Locally

Oklahoma City window installation splits between large national franchises (like Renewal by Andersen or local Andersen dealers), independent glass shops, and general contractors who subcontract glazing work. Renewal by Andersen emphasizes energy-efficient fiberglass frames and charges premium pricing, typically $600 to $1,200 per window installed. Duncan Glass & Mirror, as an independent shop, offers more flexibility on frame materials and glass choices and generally undercuts franchise pricing by 20 to 35 percent on comparable projects. The trade-off is that franchise chains offer corporate-backed warranties, while Duncan relies on manufacturer warranties for the glass and frames plus its own labor guarantee. Choose Duncan Glass & Mirror if you need custom sizing, want to mix frame materials across windows, or prefer working directly with the fabricator rather than a sales office. Choose a national franchise if you prioritize brand-name warranty backing or need a financing plan through the parent company.

Who This Shop Suits and Does Not Suit

Duncan Glass & Mirror works best for homeowners doing a partial window replacement (one to four windows), those with non-standard window openings, and anyone who wants to keep costs down on a straightforward install. The shop also attracts customers needing custom mirror work or glass fabrication alongside window jobs. The business is not ideal for someone seeking same-day or next-week installation; custom windows typically require two to four weeks lead time depending on frame and glass options. Customers expecting turnkey financing or a corporate warranty program should look elsewhere.

What the First Visit Involves

Contact Duncan Glass & Mirror by phone to schedule a free in-home or on-site estimate. A technician will measure existing windows, assess frame condition, and discuss frame materials and glass options. Bring photos of the room or exterior if remote consultation is possible. The shop will provide a written quote with materials, labor, and installation timeline. Once you approve, fabrication begins; installation typically happens four to six weeks later depending on the order queue. Installation itself usually takes a single day for a typical residential project.

Hours, Location, and Logistics

Duncan Glass & Mirror operates as a shop-based business in Oklahoma City. Hours and exact location should be confirmed directly by phone, as hours can shift seasonally or by appointment. Parking is available on-site. The shop performs both in-shop fabrication and on-site installation, so you will not need to transport large glass pieces yourself. Installation crews bring their own equipment and protective materials.

Duncan Glass & Mirror fills a practical middle ground in Oklahoma City's window market, offering customization and direct pricing without the overhead of a franchise operation or the wait times of a general contractor referral.
