ES Windows Construction in Westgate, FL | Rowan Construction Group West Palm Beach
We provide independent ES Windows sales, installation, and repair across Westgate, FL, with crews that know the difference between a Palm Beach County permit and a City of West Palm Beach permit - because in Westgate, that distinction determines whether your job starts on time or sits in the wrong queue for two weeks. Many of our customers come to us after Kitchen Remodeling - Westgate or other projects taught them how much permitting details matter. Our difference here is simple: we’ve worked on enough ES Windows units in Westgate’s 1950s-1970s CBS homes to know that the frame is rarely the only problem.

Why Westgate Residents Choose Us for ES Windows Service
Grant Rowan grew up in Los Angeles watching his uncle frame houses in the San Fernando Valley, then trained at Los Angeles Trade-Technical College before running commercial and residential job sites across Southern California. For the past several years, he and our crew have applied that same discipline to West Palm Beach-area projects, including work along Flagler Drive. That background shows up in how we handle ES Windows in Westgate - we don’t guess at why a sliding door is binding; we measure the slab settlement, check the anchor schedule, and tell you whether it’s a roller or a foundation issue before we quote. The same precision applies to our Bathroom Remodeling - Westgate work.
We’re not a manufacturer’s authorized dealer. We’re an independent construction company that has installed and serviced ES Windows products across Palm Beach County for years because they’re a common spec in Westgate’s post-Andrew retrofit market. We know the 700 Series single-hung installation tolerances, the 800 Series door flashing details, and where the corner welds on older units typically fail after a decade of UV exposure. Our crews carry OEM replacement rollers, locks, and gaskets for current ES Windows lines, and for discontinued series we source aftermarket impact-rated hardware that meets Florida Product Approval. Every visit includes a documented photo record - standard, not an upgrade - and every quote is a flat written price with a written scope before anyone picks up a tool. Under Clause 1 of the Haven Standard, that’s non-negotiable.
Westgate homeowners tend to research contractors the way they research appliances: they read the three-star reviews, they want numbers they can screenshot, and they prefer a text confirmation to a phone promise. We built our process for exactly that customer.
Common ES Windows Construction Problems We Solve in Westgate

- Water infiltration at sill pans and corner welds. On ES Windows 700 Series single-hung units, we regularly find water intrusion at the sill pan and corner welds after 8-12 years of South Florida’s UV index and driving rain. In Westgate’s older CBS homes, the original block openings were often not re-flashed during prior replacements, so the window frame becomes the path of least resistance for water. We cut back the block, install a code-compliant sill pan and flashing, then set the replacement unit with stainless anchors.
- Sliding glass door rollers binding or sagging. The ES Windows 800 Series impact sliding glass door carries heavy laminated glass, and the rollers take the load. In Westgate’s 1950s-1970s slab-on-grade homes, minor slab settlement is common - not dramatic, but enough to throw door alignment off by an eighth of an inch. That slight rake accelerates roller wear and track damage. We evaluate whether the fix is OEM roller replacement or whether the slab movement requires reframing the opening.
- Stress cracks and failed perimeter sealant on west- and south-facing units. Palm Beach County’s extreme UV exposure degrades sealant faster than most of the continental US. Combine that with high water table pushing moisture through masonry walls, and you get stress cracks in impact glass panes and delaminated perimeter seals. We see this most often on ES Windows units that face the afternoon sun without adequate overhang protection.
- Corroded or undersized anchor fasteners. When we pull ES Windows units for renovation in Westgate, we frequently find anchors that don’t meet current Florida Building Code wind-load schedules. The original installers may have shimmed poorly or used fasteners rated for static loads, not the cyclic wind pressures that post-Andrew codes address. We replace with stainless steel anchors sized to the specific wind zone and substrate condition.
- Failed units in unpermitted additions. Westgate has a long history of homeowners adding rooms or enclosing porches without permits - a pattern common in this older working-class neighborhood. Those unpermitted additions must be disclosed and resolved before any new permitted ES Windows work can close. We’ve seen this double the scope of otherwise routine projects, and we flag it early in our assessment so the homeowner understands the full path to code compliance.
Before
AfterES Windows Service in Westgate: What Local Conditions Mean for Your Equipment
Because Westgate is unincorporated Palm Beach County, every ES Windows replacement requires a permit through the Palm Beach County Building Division - not the City of West Palm Beach - and the county’s product-approval review specifically flags ES Windows units installed in post-WWII CBS homes that lack a continuous load path. This is a step that would not apply in a neighboring municipality with different plan-review triggers. What that means in practice: when we quote an ES Windows installation on a home off Westgate Avenue or in the surrounding blocks, we inspect for hurricane straps, anchor bolt patterns, and rim joist continuity before we submit plans. If the load path is broken - common in 1960s CBS construction that predates Hurricane Andrew by three decades - the permit review will catch it, and the homeowner faces a choice between structural upgrades and a rejected permit. We build that assessment into our initial site visit so the quote reflects reality, not optimism. The county’s inspection schedule also differs from municipal timelines; we know their walk-through preferences and typical turnaround, which keeps projects moving rather than stalling at the permit counter.
ES Windows Models & Products We Service in Westgate

We work on the full range of ES Windows impact-rated products common in Palm Beach County installations:
- ES Windows 700 Series Impact Single-Hung - the workhorse of Westgate retrofits, often specified where original aluminum single-hungs failed
- ES Windows 800 Series Impact Sliding Glass Door - heavy-glass units where roller maintenance and sill pan integrity are critical
- ES Windows 500 Series Impact Horizontal Roller - popular for porches and additions, where we check frame squareness against settling slab conditions
- ES Windows ADS 3500 Series Fixed Impact Window - non-operable units where sealant failure and anchor corrosion are the typical service triggers
Our Westgate crews stock OEM replacement rollers, locks, and gaskets for current series. For discontinued lines, we source aftermarket impact-rated glass and hardware that meets or exceeds Florida Product Approval. We evaluate repair versus replacement honestly: if the frame and anchors are sound, a roller and seal refresh can add years of service. If the frame is cracked or the opening lacks proper flashing, full replacement is the only code-compliant path. ES Windows sales & service details are available for homeowners comparing product lines.

FAQs - ES Windows Construction in Westgate
Westgate is unincorporated, so permits run through the Palm Beach County Building Division, not the city. The county’s plan review includes a product-approval check and, for older CBS homes, a load-path assessment that city permits may not trigger. We handle the submittal and scheduling as part of our standard process. Call (561) 475-3903 to schedule your free estimate.
Often it’s repairable. We inspect the rollers, track condition, and slab alignment first. If the frame is square and the anchors are sound, an OEM roller replacement and track cleaning typically resolves binding. If the slab has settled or the frame is racked, replacement with proper shimming and a code-compliant sill pan is the durable fix. Call (561) 475-3903 for an assessment - estimates are free.
Palm Beach County’s water table sits 18-36 inches below grade, which means moisture wicks through concrete block walls continuously. Without proper sill pan and flashing detail, that moisture finds the path of least resistance at window openings. We install continuous sill pans and back dams on every ES Windows replacement in Westgate, not as an upgrade but as standard practice.
Yes, ES Windows impact-rated lines carry Florida Product Approval, which is mandatory for any new installation in Palm Beach County. The county’s building division verifies this approval during plan review. We confirm the specific approval number for the unit we’re installing and include it in our permit submittal so there’s no hold-up at inspection.
Window replacement in Westgate typically runs $4,500-$15,000 depending on opening count, condition of the original block, and whether structural upgrades are needed for permit approval. Impact window installations range $8,000-$25,000 for full-home specifications. Every quote is written and flat-priced before work begins. Call (561) 475-3903 for an exact number - estimates are free.
