ES Windows Custom & Geometric Windows in Miami Lakes: What to Know First

We install and service ES Windows custom and geometric units in Miami Lakes as an independent provider, with most measured surveys scheduled within two business days and written pricing delivered before any work begins. Custom shapes, arched tops, and oversized configurations typically run $890 to $2,400 per opening depending on glazing specification and structural reinforcement needs. We do not quote from photographs; Haven Clause 1 requires a measured survey that becomes the written scope.

This page is for Miami Lakes homeowners who already have ES Windows products and need custom or geometric replacements, or who are specifying ES Windows for new openings with non-standard shapes. Call (786) 755-8730 to schedule a measured survey. The quote you receive is the document we work from.

How ES Windows Products Fail - and How We Fix Them

• ES-7000 series fixed geometric units: The thermal break in the ES-7000’s aluminum frame can separate at the miter joints of trapezoid and triangular configurations, especially where the head angle exceeds 30 degrees. We see this in Miami Lakes homes with cathedral-style great rooms where the original installer didn’t account for thermal cycling across the south-facing span. We remove the sash, re-weld the frame corner with a reinforced gusset, and reset the unit with backer rod and silicone compatible with ES Windows’ anodized finish.
• ES-8000 impact-rated arched windows: The laminated glass in ES-8000 radius-top units can develop edge delamination at the springline where the arch meets the rectangular portion. This happens because the curved lite and flat lite expand at different rates during Miami Lakes’ afternoon rain-cool cycles. We do not attempt to re-laminate in the field. We measure the rough opening to the sixteenth, order a replacement insulated laminated unit from our ES Windows distributor, and install it with a new glazing bead profiled for the arch radius.
• ES-5000 single-hung custom sizes: The balance shoe track in oversized ES-5000 units, anything over 42 inches wide, wears eccentrically because the sash weight exceeds the standard balance spring rating. The sash creeps down or requires two hands to lift. We replace the balance system with an aftermarket constant-force coil balance rated for the actual sash weight, not the nominal size, and we stamp the new rating on the jamb sticker for the next technician.
• ES-9000 geometric mulled assemblies: Mullion posts between ES-9000 custom shapes can rotate if the original installer used standard through-mullion fasteners instead of the heavy-duty angle brackets ES Windows specifies for assemblies over 96 inches total width. We document the rotation with a level photograph, then install the correct bracket set and re-flash the mullion with peel-and-stick membrane before reinstalling trim.
• ES-6000 fixed picture windows in oversized openings: The setting block in ES-6000 units over 60 inches wide can compress permanently, transferring frame load to the glass edge and causing stress cracks that originate at the bottom corner and run diagonally. We see this in Miami Lakes ranch homes from the 1970s where a single large picture window was later replaced with a custom ES unit without upgrading the sill structure. We install a new composite setting block at the correct quarter-points and add a sill reinforcement angle if the span requires it.

Our ES Windows Custom & Geometric Windows Process

1. 1
   Measured survey. We arrive with a laser measure, level, and the ES Windows specification manual for the series in question. Sonia Raman reads the rough opening before quoting it, which is why our change-order rate stays low. The customer keeps the survey document.
2. 2
   Diagnosis and parts decision. We determine whether the fix requires an OEM ES Windows part, a quality aftermarket equivalent, or a full sash or frame replacement. We note the warranty implications of each and let the customer decide with the facts in front of them.
3. 3
   Written scope and price. Haven Clause 1: the measurement and the quote are the same document. The price is fixed. No line item can be added later without a new signed scope.
4. 4
   Installation by verified crew. Haven Clause 3: the technician who arrives is the technician on the record, background-checked, uniformed, and identified by license number. For custom and geometric work, we send a two-person crew because shaped units cannot be maneuvered solo without risking the glass or the finish.
5. 5
   Testing and documentation. Haven Clause 4: we photograph the completed installation, including the operating hardware test, the sealant bead, and the exterior trim integration. The customer receives the photo record within 24 hours. Sonia’s standing rule applies: she does not leave until the operating hardware has been tested by someone other than her.
6. 6
   365-Day Done Right Promise. Haven Clause 5: if anything in the scope is not done right, we make it right. The promise is written, not verbal, and it is stamped on every job.
