Why San Antonio Homeowners Choose ECO Window Systems Construction
We provide San Antonio Eco Window Systems service for construction, repair, and replacement across the city, from Alamo Heights to the far west side. If you own ECO windows that are binding, leaking, sweating, or sagging, we diagnose the actual failure and fix it right the first time, using manufacturer-spec parts and the city’s specific climate in mind. We are not an authorized ECO dealer, and we’ll tell you that straight. What we are is a local crew that has taken apart enough ECO windows in San Antonio homes to know exactly what fails, why it fails here, and whether your window needs a $180 part or a full replacement. Call (254) 269-5071 for a written estimate on any ECO window issue.
San Antonio is hard on windows. The same limestone dust that coats your car after a dry week also packs into ECO weep holes and weatherstripping. The hard water from the Edwards Aquifer leaves mineral crust on tracks and balances. And the summer heat, week after week above 100°F, bakes the thermal breaks and glazing seals on any window, including ECO’s. That’s the context we work in. Our team, led by Isaac Pruett, has been pulling and repairing ECO Window Systems units in this city for years, and the climate-specific failure patterns we see here are different from what a homeowner in Dallas or Houston would experience.
Know who’s coming, know what it costs, know it’s covered, that’s the whole job before the job starts.
Why Trust Mason Remodeling Co San Antonio for Your ECO Window Systems Construction?
Isaac Pruett learned construction fundamentals at Los Angeles Trade-Technical College before spending two decades on job sites across the Southwest. He and our crew have worked San Antonio jobs for years, from full gut renovations near the King William Historic District to straightforward window replacements in quiet north-side neighborhoods, and we also handle Eco Window Systems in Boerne. When it comes to ECO Window Systems, that experience means we know the difference between a balance shoe that slipped and a frame weld that cracked. We don’t guess, and we don’t sell you a replacement when a repair will do.
Every technician who arrives at your door is background-checked, identity-verified, and in a clean marked uniform. You get their name and photo before the visit, and they’ll show a photo ID badge when they arrive. That’s the Threshold Standard, and we’ve held to it on every San Antonio job since 2004, when Mason Remodeling became part of the Threshold Group family of home-service companies.
We also put every price in writing before any work starts. Not a rough estimate, not a verbal ballpark. A written line-item quote, delivered before a single tool comes off the truck. And every ECO window repair or replacement we complete is covered by our 365-Day Done Right Promise: if the work isn’t right within a year of completion, we make it right at no cost to you. Those terms are stated plainly, in writing, on every project.
Styles & brands we work with
Common ECO Window Systems Construction Problems We Fix in San Antonio
- Binding and sticking ECO 70 Series sliding panels. The interlocking rails on ECO sliding windows are machined to tight tolerances. Add a few years of San Antonio limestone dust and hard-water mineral buildup, and the rails wear and bind. The panel gets harder to open every season, and homeowners end up forcing it, which bends the rail and makes it worse. We clean and true the rails, replace worn weatherstripping, and re-lubricate with a dry silicone that won’t attract dust.
- Water pooling on interior sills of ECO 45 Series single-hung windows. The weep holes on these frames are small, and San Antonio’s fine limestone dust packs into them fast. Once they’re blocked, rainwater has nowhere to drain, so it pools inside the track and eventually rots the sash. This is the single most common ECO 45 Series issue we see in older neighborhoods. The fix is cleaning the weep channels and verifying proper sill pitch, but if rot has already set in, replacement is the honest call.
- Interior condensation and heat gain through ECO 70 Series frames. The thermal break in these frames is a plastic or rubber strip that separates the inner and outer aluminum to reduce heat transfer. Under San Antonio’s intense UV exposure, that thermal break deteriorates faster than the manufacturer’s average-service-life charts suggest. When it fails, you get interior condensation in winter and noticeable heat gain in summer. The fix is a frame inspection and, depending on severity, a full replacement rather than a patch.
- Sagging casement sash on ECO ImpactGuard models. ImpactGuard casement hinges carry a heavy sash, and the tension mechanism that holds the sash open gradually loses grip. Once the hinge sags, the sash no longer seats flush against the weatherstripping, which means air leaks, and in a summer storm, water intrusion. We replace the hinge set with manufacturer-spec parts and reset the sash alignment so it closes tight.
- Bowed frames and slipped balance shoes on ECO 45 Series single-hung units. In San Antonio’s expansive clay soil, the house moves. Foundation movement transfers to window openings, and a window that was square when installed can rack just enough to bow the frame. The sash then slips its balance shoe and won’t stay up. On a 1970s ranch near Woodlawn Lake, our crew pulled a bowed ECO 45 Series single-hung where the sash had slipped its balance shoe. We replaced both balances with calibrated aftermarket springs and reset the sash, then sealed a cracked glazing bead to stop the air leak.
ECO Window Systems Parts & Our Repair-vs-Replace Approach
ECO Window Systems does not sell parts directly to independent service providers like us. So we source manufacturer-spec aftermarket parts, balances, locks, rollers, and weatherstripping, from industrial suppliers we’ve vetted over years of use. These are not generic, one-size-fits-all pieces. They’re calibrated to specific ECO frame profiles and sash weights, and they meet or exceed the OEM specifications. For most balance, lock, roller, and weatherstripping failures, a part swap gets your window working like new.
But we’re honest about the line between repair and replacement. If your ECO frame has a cracked weld at a corner, or the hardware is seized beyond a simple swap, we’ll tell you that patching it would be throwing money away. Full replacement with a new ECO unit or a comparable alternative is the right call in those cases. We’ll quote both options when both are viable, and let you decide with real numbers in front of you. Call (254) 269-5071 for a free assessment.
Our ECO Window Systems Service Process, Step by Step
- 1
Diagnosis. Our technician inspects the frame, sash, glazing, hardware, and surrounding opening. For ECO windows specifically, we check weep hole function, thermal break condition, balance tension, and rail wear. We document what we find and explain it in plain language.
- 2
Written estimate. You get a line-item written quote before any work starts. It covers parts, labor, and the exact scope. No verbal ballparks, no surprise invoices later.
- 3
Repair or replacement. For repairs, we use manufacturer-spec aftermarket parts matched to your ECO model and series. For replacements, we order exact or compatible units and handle the full install, including any needed flashing and sealing around the opening.
- 4
Testing and verification. We test operation in both directions, check for air and water infiltration, and verify the sash seats flush. For casement and sliding units, we confirm smooth travel and correct lock engagement.
- 5
Warranty activation. Your written guarantee is issued on the spot. It states coverage terms plainly, including what’s covered, what’s excluded, and for how long. The 365-Day Done Right Promise applies to every ECO repair and replacement we complete.

AfterECO Window Systems Products We Service & Install in San Antonio
Our crew handles ECO Window Systems Construction in Selma, TX and throughout the area, working on the full range of residential lines including the ECO 45 Series single-hung, the ECO 70 Series sliding, the ECO ImpactGuard casement, and the ECO 8500 picture window. Each of these has different frame profiles, hardware, and failure patterns, and we know the particular weaknesses of each. We stock common aftermarket balances, locks, rollers, and weatherstripping for these lines locally, which means most repairs don’t wait on a two-week parts delivery. If you’re not sure which ECO series you have, call us, we’ll help you identify it from a photo or from the etching on the glass corner.
We Also Service These Brands
While this page covers ECO Window Systems, our team works across the broader home as General Contractor services, not just the windows. We install and service KraftMaid cabinetry, Cambria and Silestone surfaces, and Kohler fixtures as part of larger kitchen and bath projects. That multi-brand capability means we can handle the windows and the room around them in one coordinated job.
FAQs, ECO Window Systems Construction Service in San Antonio
Hard-water mineral buildup and limestone dust grind into the interlocking rails on ECO sliding windows. As the metal wears, the panel binds. Summer heat makes the frame expand slightly, tightening the clearance even more. The fix is a rail cleaning and truing, plus replacement of worn weatherstripping. Call (254) 269-5071 for a diagnosis, we’ll tell you if it’s a simple service or a parts replacement.
In most cases, a full sash replacement is the better fix for ECO ImpactGuard casements. The impact-rated glazing is bonded into the sash frame, and separating it in the field compromises the impact rating. A new sash restores both the seal and the impact certification. We’ll quote the sash replacement and explain the trade-off before you commit.
That’s almost always blocked weep holes. San Antonio’s fine limestone dust packs into the small drain channels on the ECO 45 Series frame, and rainwater backs up into the interior track. The first step is cleaning and verifying the weep path and sill pitch. If the sash has already rotted, replacement is the only real fix. Call (254) 269-5071 and we’ll assess which situation you’re in.
We do both. If your ECO window has failed beyond a safe, warranted repair, we install new ECO units or a comparable alternative. Same process applies: written price up front, clear scope, and the 365-Day Done Right Promise on the completed installation.
In San Antonio, interior condensation on ECO 70 Series windows usually points to a deteriorated thermal break, not necessarily a manufacturing defect. The break material degrades under our intense UV exposure faster than in cooler climates. Once it fails, the inner frame surface gets cold, and indoor humidity condenses on it. The fix may be frame replacement. We’ll inspect and tell you straight.
ECO window replacement in San Antonio typically ranges from $4,500 to $15,000 depending on series, size, and opening count. Impact window installation ranges from $8,000 to $25,000. Below are our current price ranges.
| Service | Typical Range |
|---|---|
| Window Replacement (ECO) | $4,500 – $15,000 |
| Impact Window Installation (ECO) | $8,000 – $25,000 |

No. We are an independent ECO Window Systems service provider. We have no manufacturer affiliation, which means we’re free to recommend the most cost-effective repair or replacement for your situation. We use manufacturer-spec aftermarket parts because ECO does not sell directly to independent shops like ours. That independence is exactly why we can be straight with you about repair versus replace.
ECO does not sell OEM parts to independent providers. We source manufacturer-spec aftermarket balances, locks, rollers, and weatherstripping that meet or exceed OEM specifications and are calibrated to your specific ECO series. For glass, we use certified impact-rated units on ImpactGuard models so the rating stays intact.
Most balance, lock, roller, and weatherstripping repairs are done in one visit. Full window replacements for multiple openings typically run one to two days depending on count and access. Our written estimate will state the expected timeline. Call (254) 269-5071 for a schedule on your specific job.
We service and install the ECO 45 Series single-hung, ECO 70 Series sliding, ECO ImpactGuard casement, and ECO 8500 picture window. If your unit is from a different ECO line, ask us, we’ll identify it and confirm parts availability before you spend a dime.
If your ECO window is under active manufacturer warranty, any third-party repair can potentially impact that warranty. We’ll flag that risk before any work starts. For windows out of warranty, our own 365-Day Done Right Promise applies to the repair or replacement we complete, with terms in writing.
