CGI Construction in Tampa, CA | Rowan Construction Group
We provide independent CGI service across Tampa, and we’re not manufacturer-affiliated or authorized. What sets our CGI work apart here is simple: we know how sinkhole disclosure rules and hurricane wind-load codes interact on Hillsborough County block houses before we ever touch a window opening. If you need CGI windows serviced, retrofitted, or replaced in Tampa, call Rowan Construction Group at (470) 298-9650 for a written estimate.
Why Tampa Residents Choose Us for CGI Service
Our crews work on CGI-built additions, remodels, and storm retrofits across Tampa weekly, and we also offer Tampa Driveway & Pavers services. We know how CGI’s aluminum, vinyl, and steel products behave in Hillsborough County’s wet, wind-driven climate because we cut, flash, and tie into them on real houses here, not from a spec sheet. Grant Rowan founded this company in 2007 after training in construction technology at Los Angeles Trade-Technical College, where framing, concrete, and estimating were the curriculum before he ever took a paying job. That background matters when a CGI window frame pulls loose from a 1960s block wall in Seminole Heights and the fix requires re-anchoring, not just re-caulking. Every Tampa job gets a flat written price before work starts, background-checked crews, and a documented photo record when the crew leaves. We stock CGI factory parts locally for fast turnaround, and when a line is discontinued, we machine-match aluminum extrusions rather than forcing an aftermarket copy that won’t seat.
Common CGI Construction Problems We Solve in Tampa

- Frame screws backing out of block walls. On older CBS homes near the bay, original installers often skipped epoxy anchors. The salty, humid air accelerates rust and loosens frames. We re-anchor with stainless epoxy and reset the window.
- Aluminum cladding trapping condensation over wood buck frames. CGI cladding over a wood buck with taped flashing instead of shingled flashing holds moisture behind the nailing flange. In Tampa’s June through September rainy season, we find soft, moldy bucks inside Seminole Heights remodels. We rebuild the buck with pressure-treated lumber and flash the perimeter shingle-style.
- Older non-impact sliders leaking horizontally in tropical downpours. Worn wool pile weatherstripping on CGI’s older sliders lets water wick into slab edges in Palma Ceia lanais. We replace the pile, check the track drainage, and seal the exterior flange correctly.
- Weep holes clogged on Estate lines in flood-zone remodels. Standing water from clogged weep holes weakens mullions and causes bottom-rail sag on older CGI Estate windows. Clearing weep paths is routine, but a sagged bottom rail needs reglazing or replacement.
- Fixed-panel hurricanes rattling after bay thunderstorm pressure cycling. Shallow fin channels loosen under repeated pressure shifts from Tampa’s afternoon storms. East Tampa bungalows get service-call rattles from exactly this. We tighten the fin channels and install supplemental clips where the frame allows.

AfterCGI Service in Tampa: What Local Conditions Mean for Your Equipment
Tampa is the only major Gulf Coast city where a typical renovation permit for a post-WWII CBS home can require a sinkhole disclosure and a geotechnical boring before you even touch a CGI window opening, which is why our Fence Installation - Tampa team understands local building complexities. Hillsborough County’s karst limestone shelf shifts more than neighboring Pinellas County’s geology, and cutting a larger lintel for an impact window sometimes exposes hidden cavity settlement behind the block face. That means a window retrofit on a 1963 house off Idlewild Avenue in Seminole Heights is not the same job as the identical retrofit fifteen miles west in St. Pete. The permit reviewer may ask for ground-penetrating radar evidence before approving the opening change. Skipping that disclosure can void a homeowner’s insurance coverage on the finished structure. We factor that into every Tampa estimate because the paperwork is part of the job, not an afterthought.
CGI Models & Products We Service in Tampa

We service the CGI Sentinel® Series impact windows, the Estate Collection impact windows, the Commercial/Architectural Series (C-250, C-300), and the Estate casement and single-hung lines. Our parts approach is OEM-first: balances, weatherstripping, and locking hardware come from CGI when available because the extrusion profiles are proprietary and aftermarket copies don’t seat correctly. For discontinued CGI lines, we machine-match aluminum extrusions and glass packs locally so a partial window replacement in Palma Ceia doesn’t leave a mismatched finish. We also stock common CGI hardware in the Tampa area for faster turnaround than ordering from a distributor. Related work includes CGI sales & service, impact window installation, emergency storm damage repairs, and roof repairs where CGI frames tie into the building envelope.
CGI Service Pricing in Tampa
CGI work pricing in Tampa depends on what the frame condition actually is once we open the wall. A straight window swap runs differently from a replacement that requires rebuilding a rotted buck or re-anchoring a frame into hollow block. Here are our Tampa market price ranges for CGI work:
| Service | Price Range (Tampa) |
|---|---|
| Impact Window Installation | $8,000 - $25,000 |
| Emergency & Storm Damage | $400 - $1,800 |
| Roof Repair (CGI tie-in work) | $400 - $1,800 |
Every estimate is a flat written price with a written scope, not a phone-number guess. Call (470) 298-9650 and we’ll put the number in writing before anyone picks up a tool.

FAQs - CGI Construction in Tampa
Yes, it can. Hillsborough County building officials may require a sinkhole disclosure or geotechnical boring before approving a larger CGI window opening on a post-WWII CBS home. We handle that paperwork as part of the estimate. Call (470) 298-9650 and we’ll tell you what your specific address triggers before you spend anything.
Usually not if the remodel changes the opening size or triggers a substantial improvement review. FEMA flood-zone remodels in Tampa require impact-rated or flood-vent compliant openings under current Florida Building Code. Non-impact CGI sliders generally fail that review and need replacement. We’ll walk you through what the permit reviewer will ask for. Call (470) 298-9650 for a free assessment.
Tampa’s afternoon thunderstorm pressure cycles loosen shallow fin channels on fixed-panel CGI hurricanes over time. Temperature swings from winter to summer expand and contract the aluminum frame, compounding the loosening. We tighten the fin channels and add supplemental clips where needed. This is a common East Tampa service call.
We can machine-match the aluminum extrusion profile and glass pack locally for most discontinued CGI lines. The finish match won’t be perfect on a twenty-year-old frame, but it’ll be close enough that only a close inspection catches the difference. We always show you a sample before ordering.
Yes. Replacing an impact-rated window in Tampa requires a permit, and in flood zones that permit review may include elevation certificate checks. We pull the permit, schedule the inspection, and pass the final. Call (470) 298-9650 to get the process started.
