Thermal Windows · Dallas, TX
Entry & Patio Doors
Entry doors and patio sliders — measured, built and installed factory-direct, with locks and glass that do their jobs.
Doors are the openings you touch every day, and Thermal Windows treats them with a manufacturer's seriousness: entry doors that seal like they mean it, and patio sliders that roll like they are new — and keep rolling that way. We measure, build or order to the opening, install and adjust with our own crews across Dallas and Fort Worth.
The factory difference shows in the details: tracks and rollers specified for the panel's weight, multi-point locking that pulls the door into its seal evenly, and glass packages that stop a west-facing slider from cooking the room it serves. One accountable company, from the estimate to the final adjustment.
What You Get with Our Entry & Patio Doors

Multi-panel and oversized patio doors from the factory that builds big glass every day.
Energy glass
Insulated low-E packages that stop the patio door from being the room's heating and cooling leak.

Multi-point locks and laminated options spec'd at the estimate to your comfort.
Installed by the maker
Measured, built or ordered, installed and adjusted by Thermal Windows' own team.
Options & Materials
Door work starts with the opening's job: front entries are about presence, security and seal; patio doors about glass area, operation and traffic. Materials and glass packages follow that job — including laminated security glass and serious low-E for west sliders that bake all afternoon. Screens, sidelites and transoms are spec'd at the same visit. Because the factory is ours, odd sizes are a measurement, not a surcharge category. Bring a photo of the current door and the operation complaint ('sticks,' 'whistles,' 'drags') — diagnosis starts there.
How the Job Works, Step by Step
- 1
Consultation & design
We start with your windows, your light and your privacy needs. You see materials and samples, we take exact measurements, and together we settle the design, finish and hardware for every opening.
- 2
Written quote, no pressure
You receive a written quote covering making, delivery and installation — the full job, itemized. Take your time to compare; the price does not change because you thought about it.
- 3
Custom manufacturing
Your order is made to measure in our own workshop. Because we build it ourselves, odd sizes, arches and specialty shapes are normal work for us — not expensive exceptions.
- 4
Professional installation
Our own installers fit the finished products, level and secure every unit, adjust the operation and check the finish in daylight before they call the job done.
- 5
Walkthrough & support
We walk every room with you, show you how to operate and care for everything, and leave you with our phone number. If anything ever needs adjusting, you call the people who made it.
Care & Maintenance
Sliding doors: keep the track vacuumed and the rollers lubricated — grit is what kills patio doors. Entry doors: check weatherstripping yearly and lubricate locks and hinges; finishes on sun-blasted entries appreciate an annual look. If operation changes — dragging, sticking, whistling — call while it is an adjustment, not a repair.
What Affects the Price?
No two homes in Dallas are the same, so honest pricing starts with a look at your actual project. These are the factors that move the number most:
- Door type and size — standard or oversized
- Material and glass package
- Security hardware selected
- Existing opening condition
- Screens and any sidelite/transom work
For general planning numbers, see our Price Guide — those are market ranges, not our prices. Your exact, written price comes free with your quote: call (214) 630-5885.

Entry & Patio Doors — Frequently Asked Questions
Do you install sliding patio doors?+
Yes — patio doors are a core part of this service, from standard two-panel sliders to wide multi-panel units, built and installed factory-direct.
Are your doors energy efficient?+
Insulated and low-E packages are standard options, and laminated security glass is available. In Dallas, the glass spec matters as much as the door — west-facing sliders especially.
What about security?+
Multi-point locking, laminated glass options and quality deadbolt hardware can all be specified at your estimate — tell us your priorities and we will build the package.
Can you match my existing door style?+
In most cases yes — doors are a full service here, measured and manufactured or ordered to your opening and installed by our crews, sidelites and transoms included.
How much do entry & patio doors cost?+
The honest answer is that it depends on size, material and the condition of the existing opening. Beware of anyone who quotes a firm price without measuring. Thermal Windows measures first and then gives you a written quote with the full price — free — so you can compare it properly.
How long does a typical entry & patio doors project take?+
Measuring and ordering take the first part of the timeline; the on-site work for most homes is completed in a day. Larger or custom projects take longer, and we give you the schedule in writing before you commit, so you can plan around it.
Do you offer free estimates?+
Yes — call (214) 630-5885 and we will arrange a free consultation and written quote. There is no obligation and no pressure to decide on the spot.
Do you serve my part of Dallas?+
Thermal Windows serves the areas listed on our Service Areas page. If your neighborhood is close to a listed area but not named, call us — we will tell you straight away whether we can reach you.
What should I prepare before installation day?+
Clear the area around each opening, take down curtains or blinds if we are not replacing them, and move fragile items away from the work zone. Our team protects floors and furniture, and removes the old units and packaging when the job is done.
Can entry & patio doors be customized for unusual sizes or shapes?+
In most cases, yes. Arches, angled tops, oversized openings and out-of-square frames are measured individually and made or ordered to fit. Bring us the awkward opening — it is usually the one that benefits most from a custom solution.
What information helps my quote be accurate?+
Rough measurements (width × height in inches), a photo of each opening, and a note about what you want to change. Send those when you call (214) 630-5885 and your written quote will be faster and closer to the final number.
What happens if something is not right after the job?+
Call us. Thermal Windows stands behind its work: if something we supplied or installed is not right, we come back and make it right. That is how a local business keeps its name — one fixed problem at a time.
