CGI Construction in Jacksonville, FL

CGI Construction in Jacksonville, CA | Rowan Construction Group

Quick answer: We’re an independent Jacksonville construction firm that services, repairs, and installs CGI windows, doors, and storefront systems daily. The one thing that makes our CGI work here different is that we deal with Duval County’s consolidated permit authority and inland flood-zone requirements on nearly every job. If you own a home in Jacksonville with CGI products, you need a crew that understands how this city’s permit process and humidity interact with those specific frames. Call (470) 298-9650 for a free estimate and we’ll have someone out to look at your windows within the week.

Why Jacksonville Residents Choose Us for CGI Service

We work on CGI products in Jacksonville the way a mechanic works on a car they see every day. Not as a manufacturer affiliate or authorized dealer. We’re independent, and that matters because we tell you when a repair is worth doing and when it isn’t. Grant Rowan, our owner, trained in construction technology at Los Angeles Trade-Technical College and has spent two decades opening up walls, pulling window frames, and documenting what he finds. That paperwork habit matters more on this coast than most. When a Jacksonville inspector asks for documentation on a flood-zone retrofit, we already have it because we photograph every visit and note every substrate condition in plain terms. You get the photo record whether you ask for it or not. It’s part of how we work.

Jacksonville’s housing stock is mostly 1950s through 1980s concrete block, and those homes were built before hurricane roof-to-wall connectors became code. Replacing windows on those blocks requires different anchoring than wood frame. We know which anchors hold in 60-year-old CBS and which ones crack the block. That’s experience you can’t get from a product page.

Common CGI Construction Problems We Solve in Jacksonville

Here’s what we see repeatedly across Jacksonville homes with CGI products:

• Failed glass-to-frame seals on older impact units. In coastal and river-adjacent zones, wind-driven rain works into the rough opening once the seal goes. We find rotted CBS buck framing and hidden mold behind what looks like a perfectly good window from inside. The fix means pulling the unit, inspecting the rough opening, and resetting with proper flashing, not just re-caulking the exterior.
• Missing peel-and-stick flashing on original installations. On 1950s to 1980s concrete block homes, CGI window flanges were often nailed directly to block with no flashing tape. After decades of Jacksonville humidity, the flange-to-block bond shears and water tracks down the interior wall cavity. You’ll see peeling paint or staining at the drywall below the window first.
• Corroded casement operators. CGI casement hardware corrodes at the hinges from salt air off the St. Johns and Atlantic. The crank gears strip when homeowners force them after years of stiffness. We stock OEM crank and hinge kits because aftermarket parts never match the frame geometry and can void your wind-load rating.
• Pooling water in sill pans on flood-zone retrofits. In homes raised or re-sided for flood compliance, original CGI sill pans often were not extended over the new stucco or siding elevation. Water pools at the bottom track and rots sash corners. We correct the sill geometry when we reset the unit.
• Sash corners rotting on single-hung CGI windows in Riverside and Avondale. The pre-war bungalows in those neighborhoods have their own set of issues with moisture, old sheathing, and balloon framing. CGI units installed in the 1990s on those frames now show rot where the sill meets the jamb, and we frequently need to rebuild the rough opening before re-installation makes sense.

CGI Service in Jacksonville: What Local Conditions Mean for Your Equipment

Jacksonville is the largest city by land area in the contiguous United States, roughly 874 square miles under one consolidated Duval County permit authority. That consolidation means a single set of building rules applies from Baldwin to the beaches, which is convenient. But it also means that the same inspector who signs off on a beachfront high-rise replacement is reviewing your inland window retrofit, and that inspector works from the same flood-zone maps regardless of how far you live from the ocean. The St. Johns River flows north through the city and backs up during storms. Hurricane Irma in 2017 pushed it to historic crests that inundated Riverside, downtown, and neighborhoods miles inland. So when we pull a permit for a CGI window replacement on a 1970s ranch in Arlington or along Heckscher Drive, the inspector may require a finished floor elevation certificate before signing off, even if your house has never flooded in living memory. That’s a Jacksonville reality. Crews relocating from Orlando or Tampa routinely miss it. We plan for it on the front end of every estimate, so the permit doesn’t stall the job at inspection.

CGI Models & Products We Service in Jacksonville

We service the full CGI product range including the Sentinel Series impact windows, Estate Collection impact windows, Clad Ultimate casement windows, and the commercial storefront systems used on retail and mixed-use buildings across Jacksonville. For repairs, we stock OEM CGI hardware kits: rollers, locks, balance tubes, weatherstripping, and hinge sets. We do not use aftermarket parts because the frame geometry on CGI units is specific, and a generic roller wears the track wrong within the first year. For full-frame replacements, if the existing unit is over 15 years old or has taken storm damage, we recommend retrofitting to a current CGI impact model rather than patching a frame that has already lost its structural seal. You keep your wind-load rating, and you stop chasing the same leak every hurricane season.

FAQs - CGI Construction in Jacksonville

Do I need a permit to replace CGI windows in Jacksonville if I’m just swapping like-for-like?

Yes. Jacksonville operates under a consolidated Duval County permit authority, and window replacement requires a permit regardless of whether you’re swapping like-for-like. The city wants to verify that the new units meet current Florida Building Code for your wind zone, and if you’re in a flood zone, the inspector will want your elevation certificate on file. We pull the permit for you, schedule the inspection, and provide the documentation. Call (470) 298-9650 and we’ll handle the paperwork from start to finish.

My house is a 1970s CBS in the Westside and still has original non-impact CGI windows. Can I just install impact glass in the existing frames?

No, you can’t reliably do that. Impact-rated glass is thicker and heavier than standard glass, and the frame on a non-impact CGI unit from the 1970s was not designed or tested for that load. The frame will flex, the seal will fail, and you’ll end up with water intrusion. The code-correct approach is a full-frame replacement with a current CGI impact model, anchored properly into your CBS block with pressure-treated bucks and full perimeter flashing. That is the only way the install passes a wind mitigation inspection. Call (470) 298-9650 for a line-item quote on the replacement.

After Hurricane Irma, the St. Johns flooded my Riverside bungalow and now the lower sashes on my CGI windows stick. Is the frame salvageable?

Sometimes yes, sometimes no. It depends on whether the frame sat in floodwater long enough to corrode the internal balance tubes and warp the vinyl or aluminum at the sill. On a Riverside bungalow, the framing around the window is often old and water-damaged too. We’d pull the sashes, inspect the jamb and sill for rot, and tell you honestly whether you’re looking at a hardware replacement or a full-frame job. The inspection is part of the free estimate. Call (470) 298-9650 and we’ll look at it.

What’s the difference between a CGI impact window and a standard window with hurricane shutters for a Jacksonville home?

A CGI impact window is tested to withstand a direct hit from windborne debris without breaching. A standard window with shutters protects only when the shutters are closed and latched. So if you’re away from home when a storm approaches, your shutters aren’t up, and your standard window is your weak point. In Jacksonville, where storms can stall and the window of time to secure a house is short, impact windows are the more reliable protection. They’re also the choice that lowers homeowners insurance premiums more consistently in Florida. For a home on the St. Johns or near the beaches, we recommend impact windows over shutter-only retrofits.

Can you match the bronze anodized finish on my existing CGI Estate Collection windows when replacing just one unit on an Avondale historic home?

Yes, we can match the bronze anodized finish. CGI’s Estate Collection uses a specific anodized bronze that is still available from the manufacturer, and we order the replacement sash or full unit in that finish rather than trying to paint or wrap a mismatched frame. On an Avondale historic home, finish consistency matters as much as structural performance. If the damaged unit is older and the finish has faded, we’ll also discuss whether refinishing the surrounding units makes sense so the one new window doesn’t stand out. Call (470) 298-9650 for a free estimate on the replacement.
