Fast, Reliable Window Replacement Across Highland Park
Window replacement in Highland Park runs $900 – $4,200 per opening installed, depending on whether you need custom steel casements, clad wood to match original trim, or a simpler insert. We answer the phone when you call, show up in the window we gave, and hand you a written price before any work starts. That matters here more than most places. Highland Park’s homes are not off-the-shelf houses, and the window work they need is not off-the-shelf either. Owen Satterfield runs our Dallas-Fort Worth operation, and he has spent years working through the town’s specific preservation and wind-load requirements. Call (361) 441-0865 for a free estimate on your Highland Park home.
Why Westlight Windows Dallas Is Highland Park’s Preferred Window Replacement Company
We have replaced windows in Highland Park long enough to know what the town actually requires, not what a generic estimate assumes. Highland Park homeowners call us because our quote already accounts for preservation review, custom sightlines, and wind-load documentation before we ever set a soffit ladder. That saves people from the two-week stall that happens when a contractor pulls up a standard vinyl unit and the town says no.
Every job here runs on the Kingswell Guarantee, which means four things in writing: the price before the work, a real arrival window, a clean job site, and a written guarantee on the completed work. If a repair fails within the guarantee period, we return and correct it at no charge. That is the 365-Day Done Right Promise, and it applies to every Highland Park job we do. Background-checked, uniformed technicians handle the work, so you know exactly who is walking through your front door.
Highland Park customers have told us the same thing for years: other companies quote a range, then revise it at the door. We do not do that. Your written price is your price. And when you call, a live person answers, 24 hours a day. Not a voicemail box. Not a chatbot.
Window Repair in Highland Park
Window repair in Highland Park is often the smarter call than replacement, especially in older homes where original steel casements or wood sashes are still sound. Repair work here includes reglazing loose panes, replacing failed seals, adjusting hardware, and weather sealing around frames that have shifted in Highland Park’s clay soil. Most window repairs in Highland Park run $150 – $650 per window, with full hardware replacement on steel casements running higher. When a 1930s casement has failed balance arms or corroded bronze operators, repair preserves the original character and avoids a preservation review entirely.
Steel Casement Restoration
Many original Highland Park steel casements from the 1930s are still in place. They are thin, elegant, and specific to the house. Repairing them means removing corrosion, re-welding broken corner joints, and replacing worn operator arms with era-appropriate hardware. This is a niche skill most window companies never develop, but it is routine here.
Seal Failure and Glass Replacement
A fogged pane in a Highland Park window means the insulated glass unit has lost its seal. In a home where sightlines are everything, replacing just the glass rather than the whole sash keeps the frame profile intact. Insulated glass replacement runs $180 – $500 per pane depending on size and whether the glass needs a low-e coating (a thin layer that reflects heat back out in a Highland Park summer).
Window Replacement Company in Highland Park
As a window replacement company working across Highland Park, we handle full frame replacement, insert windows, and energy-efficient upgrades for homes from the 1920s through new construction. Full frame replacement in Highland Park most often runs $1,800 – $4,200 per opening because it involves removing the existing frame to the rough opening, addressing any rot or settling, and installing a unit built to the exact dimensions of the original. Insert replacement runs $900 – $2,200 per opening, sliding a new sash and frame into the existing opening. That works when preservation rules allow it and the existing frame is sound.
Full Frame Replacement
When a Highland Park home has water damage around old windows or a frame that has settled out of square, an insert will not solve the problem. Full frame replacement removes everything down to the studs, lets us correct the rough opening, and installs a unit that seals properly. On Preserve District homes, this is also the route when original sashes are too far gone to repair but the town still requires matching sightlines.
Energy-Efficient Upgrades
Highland Park summers are brutal, and older homes carry big cooling loads. Replacing single-pane originals with insulated, low-e glass through ECO Window Systems or ES Windows can cut heat gain dramatically without changing the look of the house. We have done this on Colonial Revivals near Armstrong Parkway where the owners wanted modern thermal performance behind period-appropriate divided lites.
Trusted Brands We Service in Highland Park
We stock and install products from eight manufacturer lines, and Highland Park jobs tend to favor three of them: ES Windows for custom steel and aluminum with historically accurate profiles, ECO Window Systems for energy-efficient aluminum and vinyl where preservation rules permit, and Therma-Tru for entry doors matched to the same architectural standards. Because we carry these lines directly rather than ordering through a middleman, lead times for Highland Park projects are shorter and we can match trim profiles, hardware finishes, and glass tints on-site. Call (361) 441-0865 and we will walk you through which product fits your house and the town’s requirements.
Common Window Replacement Problems We See in Highland Park Homes
- Off-the-shelf vinyl double-hungs failing preservation review. Highland Park’s Preservation District holds replacement windows to the original sightlines and materials. Standard vinyl units with wide, modern frames get rejected by the town, and the homeowner pays for rework.
- Windows without a large-missile rating. Hail from spring and fall thunderstorms hits Highland Park hard. Units that meet wind pressure but not impact testing will not hold up, and insurance claims can be denied if the right testing documentation is missing.
- Work done without the town’s required building permit. Highland Park requires a permit for window replacement, and unpermitted work shows up during resale inspections. Stop-work orders and fines are common when homeowners discover their previous contractor skipped the permit.
- Seal failure within the first two years. Highland Park’s heat and humidity stress sealed units fast. If the installation left gaps or the unit was not shimmed correctly, the seal fails and the glass fogs. Our guarantee covers this at no charge.
Pricing for Window Replacement in Highland Park, TX
Most insert replacements in Highland Park run $900 – $2,200 per window installed. Full frame replacement on older homes, where the rough opening must be corrected and custom trim milled, runs $1,800 – $4,200 per opening. Custom steel casement replication on a 1930s Tudor can run $3,500 – $7,000 per unit depending on size and hardware. Several things move the number: whether the home is in the Preservation District, whether original bronze or brass hardware must be restored or replicated, glass rating (standard versus impact-rated), and whether we are matching period divided lites. You get a written price before any work starts, and that number does not change at the door. Call (361) 441-0865 for a free estimate on your specific windows.

FAQs About Window Replacement in Highland Park
Highland Park replacement windows generally need a design pressure rating of at least DP 50 for most exposures, and impact-rated units with a large-missile certification are strongly recommended due to hail exposure. A design pressure rating measures how much wind and water pressure a window can take before failing, while a large-missile rating certifies that the glass can survive a 2×4-style projectile fired at the unit during testing. Highland Park sits in a region where severe thunderstorms bring both high winds and hail, so units rated for wind but not impact will not hold up the way the town expects. Call (361) 441-0865 and we will spec the exact rating your house needs.
Yes, Highland Park requires a building permit for window replacement, and inspections are part of the process. The permit application includes a scope of work with window locations, sizes, and materials. Once the permit is issued, work proceeds, and the town inspects the installation before final sign-off. Unpermitted window work surfaces later during resale inspections, and the seller can be hit with fines and the cost of rectifying whatever was done wrong. We pull permits on every job and pass inspections before calling it complete.
Generally no, not in the Preservation District. Highland Park’s town code requires historically sensitive replacements that maintain original sightlines and materials, which means standard vinyl double-hungs with wide modern frames fail preservation review. Clad wood and steel with narrow, original-profile sightlines are what pass. We have matched original 1-inch sightlines with custom ES Windows on Preservation District homes, keeping the look right while meeting modern performance standards. A standard vinyl quote will get rejected, and you will pay twice.
Documented compliance with wind-mitigation requirements can lower your insurance premium in Highland Park, because insurers discount homes with certified impact-rated openings and verified installation. The key word is documented: the insurance company needs testing certificates, product approvals, and permit records showing the units meet the rated standard. A cheap install without that paperwork does nothing for your premium, and after a hailstorm it can be the difference between a covered claim and a denial. We provide the full documentation package on every impact-rated Highland Park job.
A design pressure rating measures the structural resistance of a window to wind loads and water infiltration, while a large-missile rating tests the glass against flying debris: a nine-pound 2×4 fired at the unit at 34 mph. In Highland Park, where severe thunderstorms bring both straight-line winds and hail, the two ratings work together. A window can have a strong design pressure rating but still shatter on impact, leaving the interior exposed. For Highland Park homes, we recommend impact-rated units that carry both certifications, and we include the documentation with your job file.
