Oldcastle Windows & Doors Nationwide

Oldcastle Windows & Doors: The Boca Raton Owner’s Guide

We stock and install Oldcastle-compatible windows and doors across Boca Raton, with most replacement parts available same-day and full unit installs typically quoted between $4,500 and $15,000 depending on scope. Oldcastle’s product lines were widely installed in South Florida from the mid-1990s through the late 2010s, so most failures we see are in coastal condos near the Intracoastal and in ranch-style homes west of I-95 where the original installs are hitting 15 to 25 years. The first sign is usually a window that won’t stay open, a door that drags, or visible moisture between panes after a summer storm.

Which Oldcastle Models This Applies To

Oldcastle sold windows and doors under several series names, and the part you need depends on which generation you’re working with. The Oldcastle BuildingEnvelope residential line, common in Boca Raton multifamily builds from 2005 to 2018, used proprietary balances and weatherstrip profiles that differ from the earlier Oldcastle Glass branded units. Check the spacer bar between glass panes or the hinge mortise on doors for an embossed series code; if it’s worn, measure the visible glass dimensions and the overall frame depth, which runs 2-5/8 inch or 3-1/4 inch depending on impact rating.

We source both OEM-spec parts and quality aftermarket equivalents from suppliers who reverse-engineer to Oldcastle’s original tolerances. For non-impact units, aftermarket balances and rollers often match at lower cost. For impact-rated assemblies, we recommend OEM or tested equivalents with Miami-Dade NOA documentation, since the city’s building department enforces this strictly on replacement permits. We also stock parts for KraftMaid, Cambria, and Silestone products when your project scope extends beyond the window system itself.

Signs Your Oldcastle Windows & Doors Is Failing

• Window sash drops or won’t stay raised. The coil balance or block-and-tackle system has fatigued. In Boca Raton’s salt air, corrosion accelerates spring failure, and we see this first in east-facing units at Ocean Breeze Golf Course properties where morning salt fog lingers.
• Visible fog or moisture between glass panes. The insulated glass unit (IGU) seal has failed, breaking the argon fill and killing the thermal barrier. Once breached, Florida’s humidity enters within days, not weeks.
• Door sticks or drags at the threshold. The sill cap or adjustable riser has compressed or corroded. Oldcastle’s earlier aluminum sill designs are prone to galvanic corrosion when they contact certain concrete finishes common in Boca Raton slab construction.
• Air infiltration around frame perimeter. Compression weatherstrip has hardened or the foam-back seal has lost memory. Heat cycling in South Florida degrades EPDM rubber faster than the manufacturer’s inland lifespan charts suggest.
• Cracked or delaminating exterior cladding. The PVC or aluminum wrap has separated from the substrate, usually from moisture intrusion at a corner joint. Left unaddressed, this reaches the wood or composite frame and requires full unit replacement.

Replacement Cost & What’s Included

For Boca Raton homeowners, window replacement runs $4,500 to $15,000 for a typical whole-house scope, while single-unit part repairs start around $400 for balance or weatherstrip replacement and climb to $1,800 for full sash or IGU replacement in an impact-rated unit. The range reflects three factors: whether the original frame can be retained, if the unit is impact-rated, and whether the condo or HOA requires specific aesthetic matching.

Every quote we deliver is flat-priced with a written scope before work begins, per Clause 1 of The Haven Standard. Parts, labor, permit fees if applicable, and disposal are itemized. Our 365-Day Done Right Promise covers the installation; manufacturer warranties on the parts themselves vary by component, and we document both in writing. No change proceeds without a signed change order, which is how we’ve kept projects within a few percent of the agreed number across 4,000-plus jobs since 2007.

DIY or Call Us?

There’s a safe middle ground here. A homeowner can inspect the failure point, record the series code, and measure visible glass dimensions, all of which saves time when we arrive. What we don’t recommend: removing a fixed sash from an impact-rated unit, adjusting spring-loaded balances without proper tools, or cutting sealant beads on a unit that may be tied to the home’s wind-load certification. The spring tension in a double-hung balance can release unexpectedly, and impact glass is heavier than it looks.

We’re an independent service provider, not affiliated with Oldcastle. Our crews carry Oldcastle-compatible parts on the truck for common failures, and we bring the documentation: a photo record of the condition before we start, signed off at each phase. If you’re weighing whether to repair or replace, call (754) 254-8065 and we’ll schedule a free estimate with a written price before any work starts.
