Why Blackline

Built differently, on purpose.

Made to your exact opening

Start from a standard size or have every dimension built to your rough opening. We price on the measurements you send, so what you approve is what gets fabricated — no forcing a stock door into a custom wall.

Iron and aluminum, one team

A statement iron entry, aluminum sliders to the patio and matching windows, coordinated by one point of contact. Finishes, sightlines and schedules line up because one shop handles all of it.

Shop drawings before fabrication

Nothing is cut until dimensions, swing, finish and glass are approved on paper. Builders and architects get drawings they can check against the plans; homeowners see exactly what they are buying.

Installed by our own crews

Our crews measure, deliver and install every unit across Texas — no subcontracted installers. Thermally-broken options, Low-E and laminated glass and corrosion-resistant finishes are built for Texas heat and humidity.

Common questions.

Can you build iron doors in custom sizes?

Yes. Our standard sizes are 36" × 96" for a single door and 72" × 96" for a double door, but every design can be built to your opening — including height, width, proportions, panel layout, glass, finish and hardware. Arch and eyebrow tops are available as a custom design.

What are your lead times?

Lead times depend on the size, material and quantity of your order. Every quote includes a timeline you can plan around, and we confirm it again once shop drawings are approved.

Iron or aluminum — which is right for my project?

Iron is best for the entrance: weight, presence and divided-lite panels on entry, double and French doors. Aluminum is best for the views: slim, thermally-broken frames for sliding doors, bifold walls and large windows. Many of our projects combine both, coordinated by one team.

Is the estimate free?

Yes. Send your rough measurements and a photo of the opening and we will send back a free estimate with no obligation. A specialist reviews every request — not a call center.
