CGI Construction in Fresno, CA | Rowan Construction Group
We provide independent CGI construction service across Fresno, handling everything from Sentinel Series impact windows in 1950s tract homes to Targa storefronts in the Tower District. What sets our work apart here is that we spec around two things most contractors don’t account for: Fresno’s Title 24 solar reflectance requirements and the shrink-swell clay movement that shifts slabs under CGI door tracks. CGI sales & service is what we do, and we’ve been doing it in this valley long enough to know which components fail here and which hold up. Call (470) 298-9650 for a written estimate before any work starts.
Why Fresno Residents Choose Us for CGI Service
We run CGI product lines on Fresno job sites daily, so our independence means we call a spade a spade on what survives this climate and what doesn’t, without a factory bias. A dealer pushing OEM-only replacements has a different incentive than a contractor who has watched vinyl glazing beads warp on west-facing walls in July. Grant Rowan founded this company in 2007 after training in construction technology at LA Trade-Tech, where framing, concrete, and estimating were taught before anyone picked up a hammer. That background shaped how we approach every CGI repair: measure the substrate, document the failure, then name the price in writing. Under Clause 1 of the Haven Standard, the written price comes before any work starts. We’re an independent CGI service provider, not manufacturer-affiliated, which means we recommend what the structure actually needs, not what a factory program tells us to sell. Every visit includes a documented photo record, so you see what we found before you approve the fix.
Common CGI Construction Problems We Solve in Fresno

- Warped glazing beads on Sentinel Series windows. West Fresno’s 110°F attic-heat exposure softens the vinyl bead over five to seven years, and the seal between panes starts to fog. We pull the sashes, install stainless-steel reinforced beads, and reset the frame so the thermal cycle doesn’t repeat.
- Binding slider doors on Estate Collection tracks. Fresno’s expansive clay soil settles unevenly, and a slab-on-grade home from the 1960s or 1970s moves enough to misalign a sliding glass door track by an eighth of an inch. The door jumps or sticks. We shim the track and replace the roller trucks with heavy-duty aftermarket units that tolerate movement better than factory stock.
- Degraded Targa Series bottom sweeps. SJVAPCD construction dust and Valley fever soil fines work their way under storefront doors, and the factory sweep crumbles within a few summers. We replace them with stainless steel sweeps that seal tighter and last longer under valley dust load.
- Bent operator arms on 800 Series casements. When stucco cracks on older slab-on-grade homes, the window frame racks slightly. That bends the operator arm, and a homeowner often replaces the hardware only to have it bend again. We address the racking first, then install reinforced aftermarket operators.
- Fogged impact glass from seal failure. Once the glazing bead warps or the frame shifts, the inert gas between panes escapes and Fresno’s summer heat accelerates the fogging. Structural components like impact glass and frames usually mean full replacement, not repair, because the thermal cycling has already compromised the unit.

AfterCGI Service in Fresno: What Local Conditions Mean for Your Equipment
Fresno sits in California Climate Zone 13, the state’s most demanding zone for cooling loads, and also atop the San Joaquin Valley’s notorious expansive clay. Every significant build or addition, including any Fresno Driveway & Pavers project, must satisfy Title 24 energy compliance calibrated for a climate that routinely exceeds 105°F. Here’s what that means for a CGI owner in Fresno specifically: a roof or window package that meets code in Sacramento or San Francisco may not meet Title 24 here, because compliance requires a solar reflectance index (SRI) calculation on roof products. For CGI metal roofing, that calculation often forces the spec into specific Kynar-based colors, not just any painted finish. Contractors who never run an SRI check order the wrong roof and fail inspection. Our crews run the check before we order, because a failed inspection on a Title 24 project in Fresno means rework, not a signature. We’ve replaced CGI Sentinel Series windows in a 1962 post-WWII tract home near Fresno Street and West Avenue, where the west-facing wall regularly hit 113°F. The vinyl glazing bead had warped enough to let valley dust into the air gap. We pulled the sashes, installed aftermarket stainless-steel reinforced beads, and reset the frames with adjustable shims over the shifting slab. Tighter envelope, no heat-compromised seals through the next two summers.
CGI Models & Products We Service in Fresno

Our crews work on the full CGI residential and light commercial line, including the Sentinel Series impact windows, Estate Collection sliding glass doors, Targa Series aluminum storefront, and 800 Series casement windows. For parts, we stock heavy-duty rollers, stainless steel sweeps, and aftermarket reinforced operators locally for fast Fresno turnaround. The distinction matters: we install factory-independent replacement parts where structural integrity isn’t compromised, because OEM-only can lead to repeat failures in this soil and heat. On structural components like impact glass or frames, we recommend full replacement when settlement racking or thermal cycling has degraded the unit. That’s not a sales pitch; it’s a spec decision. Measure twice, say it once, show your work.

What drives the cost on a Fresno CGI job is the substrate, not the product line. A slider on a settled 1970s slab costs more to correct than the same door on a post-tensioned slab that hasn’t moved.

FAQs - CGI Construction in Fresno
Yes, but only if the installation accounts for frame air-sealing and the window’s orientation. A Sentinel window with a warped glazing bead lets conditioned air escape regardless of its impact rating. We install with the assumption that west-facing walls in Fresno will hit 113°F, and we document the air-seal before we call the job done. Call (470) 298-9650 for an exact quote, estimates are free.
Usually yes. We shim the track, replace the roller trucks with heavy-duty aftermarket units, and reset the frame over the shifted slab. If the slab movement has racked the door frame itself, replacement becomes the honest recommendation. We’ll show you the photo record either way before you approve anything.
It’s worth it when the SRI is calculated correctly. Title 24 in Fresno’s Climate Zone 13 requires a solar reflectance index on roof products, and CGI metal roofing in specific Kynar-based colors meets that standard. The wrong color fails inspection. We spec the SRI before ordering, so the roof you get is the roof that passes.
We can do both, and often should. Older Tower District wood-frame homes need shear-wall and foundation anchor work before new window frames go in, because a racking frame will bend new operator arms within a year. We coordinate the retrofit and the window install as one scope, with one written price, just as we do for Fence Installation in Fresno. Call (470) 298-9650 and we’ll walk the site with you.
We’re independent, not manufacturer-affiliated, so we don’t process factory warranty claims. What you get instead is our 365-Day Done Right Promise in writing: if it’s not done right, we make it right. For many Fresno homeowners, that’s a stronger guarantee than a factory program that prorates over time. We’ll review any written estimate you have, including a competitor’s quote, line by line at no charge.
