Rowan Construction Group has worked on ECO Window Systems installs and retrofits across Fresno’s post-tensioned slab homes for over a decade. We’re not a manufacturer-authorized shop, and we’ve never pretended to be. We’re an independent contractor with deep ECO product familiarity, and that independence means we call parts and repairs exactly as we see them. Our ECO Window Systems sales & service work spans every model line that’s gone into Fresno homes since the 1990s, and we write every quote flat before work starts. That’s been our rule since Grant Rowan founded the company in 2007, and it’s held across more than 4,000 projects.
Why Fresno Residents Choose Us for ECO Window Systems Service
Most Fresno homeowners who call us have already done their homework. They’ve read the three-star reviews, they’ve pulled the Title 24 checklist, and they want a contractor who can speak to the specifics. We can. Our crews have replaced ECO 3000 double-hungs in Tower District bungalows and ECO 7000 sliding doors in Woodward Park track homes, and the failure patterns differ by neighborhood, by slab condition, and by which direction the house faces. Grant Rowan trained in construction technology at Los Angeles Trade-Technical College, where framing, concrete, and estimating were taught before any paying job, and that background shapes how we diagnose: we look at the rough opening, the sill condition, and the flashing details before we ever quote a window.
Every visit includes a documented photo record of what we found and what we did. Our technicians are background-checked and uniformed, and a live person answers the phone around the clock. Under Clause 1 of the Haven Standard, the price is written before anyone starts, and no work proceeds on a change until you sign the change order. That discipline is why our Fresno projects consistently finish within a few percent of the agreed number.
Common ECO Window Systems Construction Problems We Solve in Fresno

- Dust and Delta breeze leaking through closed ECO 3000 double-hungs. Fresno’s shrink-swell clay causes sashes to bow slightly over time, leaving a telltale gap at the meeting rail that breaks the seal. We re-square the frame, replace worn balances, and restore the seal so the dust stays outside.
- Hairline stress cracks at ECO window frame corners on pre-1980 stucco homes. Post-tensioned slabs in older Fresno neighborhoods like the Tower District or central Fresno have shifted enough to transfer load through wall systems. We see the evidence as micro-cracks at the rough opening corners. When flashing or frame integrity is compromised, we recommend full replacement rather than patching.
- Rattling glass panels in ECO 5000 casements. Fresno’s 105°F summer heat snaps the vinyl retainer clips on the glazing beads after a few seasons. The glass then vibrates inside the sash frame. We replace the clips with high-heat-tolerant aftermarket parts matched to the original mill test reports.
- Grinding rollers and mid-span sag on ECO 7000 sliding patio doors. The valley’s fine blowing dust accelerates sill track wear, causing rollers to grind and the panel to drag instead of glide. We clean, realign, and replace worn rollers or tracks, and we’ll tell you honestly if replacement is the smarter long-term call.
- Failed weatherstripping leading to drafts and higher cooling bills. Fresno’s hot, dry climate degrades older weatherstripping faster than coastal air would. We replace it with compression-grade material that keeps conditioned air in and July heat out.

AfterECO Window Systems Service in Fresno: What Local Conditions Mean for Your Equipment
Fresno sits in California Climate Zone 13, which carries the strictest cool-roof and fenestration ratings in the state. City inspectors here routinely flag ECO window replacements that don’t meet the 0.22 U-factor and 0.25 SHGC maximums for the central San Joaquin Valley. That threshold is tighter than what coastal zones require and more aggressively enforced than in neighboring Madera or Kings counties. What that means for an ECO Window Systems owner in Fresno is straightforward: the window that passed inspection in Clovis won’t necessarily clear Fresno’s building department, and we size every replacement to the city’s current fenestration detail before we submit the permit package. This page gives you the exact Title 24 and clay-soil compliance checks that decide whether an ECO Window Systems replacement in Fresno passes the first inspection, details you won’t find on a generic manufacturer or contractor page.
Our crew replaced six ECO 3000 Series double-hungs on a 1962 stucco tract home near Fresno High in the Tower District after the homeowner complained of dust bleeding through closed windows. We found the frames racked from decades of slab movement along the west wall, popped the sashes, re-squared the openings with steel shims, and installed new ECO 5000 casements with low-E3 glass that cleared Title 24’s package A requirements. The building inspector signed off on the first visit because our flashing and nail fins matched the city’s current fenestration detail. That’s the difference between a crew that knows Fresno’s clay and one that’s learning it on your house.
ECO Window Systems Models & Products We Service in Fresno

We service the full ECO Window Systems residential range: the ECO 3000 Series double-hung, ECO 5000 Series casement, ECO 7000 Series sliding patio door, and ECO 9000 Series picture window. For older ECO models out of production, we source quality aftermarket replacement balances, rollers, and weatherstripping matched to the original mill test reports.

Most standard parts are stocked locally for fast Fresno turnaround, and specialty ECO components arrive within a few business days.

FAQs - ECO Window Systems Construction in Fresno
Do I need a permit to replace ECO Window Systems windows in Fresno?
Yes. Fresno requires a building permit for window replacement, and the inspector will check your new ECO units against the city’s current fenestration detail, including U-factor and SHGC maximums for Climate Zone 13. We pull the permit, schedule the inspection, and handle the paperwork end to end. Call (470) 298-9650 and we’ll include permitting in your written quote.
How does Fresno’s expansive clay affect ECO window operation over time?
Fresno’s shrink-swell clay causes post-tensioned slabs to move seasonally, and that movement transfers through stucco walls into window rough openings. ECO frames on older homes may develop corner stress cracks or sashed misalignment. The fix starts with a frame inspection to determine whether shimming and re-squaring will restore operation or whether frame integrity calls for full replacement.
Do ECO windows meet Fresno’s Title 24 energy code for replacement?
They can, but only with the right glass package. Fresno’s Climate Zone 13 requires replacement windows to hit a 0.22 U-factor and 0.25 SHGC maximum, which typically means low-E3 glazing on ECO units. We specify glass and frame combinations that clear Title 24’s package A requirements and document the ratings in your permit package.
What is the wait time for ECO Window Systems parts in Fresno?
Common parts like balances, rollers, and weatherstripping are typically available within a few business days from our local stock or regional suppliers. Specialty ECO components for discontinued models may take a week or more. We tell you the actual lead time in your written quote before any work starts.
Can you install impact-rated ECO windows for fire-prone areas east of Fresno?
Yes. For homes in WUI-adjacent foothill zones east of Fresno, we install impact-rated ECO window configurations that meet both Title 24 energy requirements and wildfire hardening standards. The written quote will break out the impact glazing and frame reinforcement separately so you can see exactly what you’re paying for. Call (470) 298-9650 for a free estimate.
