How We Build Custom Windows & Doors - Start to Finish
We’ve refined this into five clear stages so you know what you’re signing up for and when you’ll need to make decisions.
Stage 1: Field measure and forensic inspection (1-2 days). We don’t trust existing drawings for Miami Beach work. Our crew measures every rough opening, checks for concrete spalling or rebar corrosion around the frame perimeter, and documents the existing sill elevation against current street grade. In Mid-Beach MiMo buildings, we regularly find original steel frames with active corrosion that must be cut out entirely. You’ll decide at this stage whether to restore existing openings or reframe for larger units.
Stage 2: Product selection and NOA verification (1-2 weeks). This is where you choose frame material, glazing package, and hardware finish. We cross every selection against the Miami-Dade NOA database before you sign off - no exceptions. Aluminum frames with thermal breaks dominate here for corrosion resistance, though fiberglass performs well in protected bayfront exposures. You’ll receive shop drawings for approval.
Stage 3: Permitting and HOA submission (2-4 weeks). We file with Miami Beach Building Department and, where required, the Historic Preservation Board or your condo association. South Beach Art Deco properties often need board approval for any visible geometry change. We handle the drawings and correspondence, but you’ll need to sign HOA applications personally.
Stage 4: Fabrication and staging (3-6 weeks). Custom units are built to your approved shop drawings. We coordinate delivery around tidal flooding windows - truck access in low-lying zones can be impossible during October king tides. Units arrive crated; we inspect before accepting.
Stage 5: Installation and inspection (2-5 days). Demo, frame prep, installation, sealant, and hardware adjustment. Final inspection with Miami Beach Building Department confirms NOA labels and proper fastening schedule. We don’t collect final payment until you pass.
The Choices You’ll Actually Make for Custom Windows & Doors
- Frame material: aluminum vs. fiberglass vs. composite. Aluminum with thermal break is the practical default in Miami Beach - it tolerates salt air, carries the narrowest sightlines for historic compatibility, and every major manufacturer offers HVHZ-rated systems. Fiberglass insulates better but costs 15-25% more and fewer local shops can field-service it. Composites split the difference; we specify them for bayfront homes where thermal performance matters more than frame thinness.
- Impact glazing: laminated single-pane vs. insulated laminated. Single-pane laminated meets code and keeps weight down for older concrete structures with limited header capacity. Insulated laminated adds energy performance and sound damping - worth it on Collins Avenue corridor properties dealing with traffic and salt spray. The upgrade typically adds $2,000-$4,500 per project.
- Operating style: fixed, casement, projected, or sliding. Fixed picture units are cheapest and most water-resistant. Casements seal tightest for wind-driven rain but need clearance for swing. Projected windows (awning or hopper) work well in historic stucco profiles where outward swing is restricted. Sliding doors dominate for terrace access but require precise sill drainage engineering.
- Finish: anodized, powder-coated, or clad wood interior. Anodized aluminum holds up longest against salt but limits color choice. Powder coat offers any color but needs reapplication every 10-15 years in this environment. Clad wood interiors warm up living spaces but we rarely recommend full wood exteriors here - the maintenance burden is real.
- Hardware and screen package. Multi-point locking is standard for HVHZ. Screens are optional on fixed units; we recommend them for operable windows in garden-level condos where insects are persistent. You’ll choose handle style and finish at the shop drawing stage - changes after fabrication are expensive.
What Custom Windows & Doors Costs in Miami Beach, FL
Custom windows and doors in Miami Beach fall between $8,000 and $25,000 for typical residential projects. Small condo jobs with 3-4 openings in standard sizes land at the low end. Whole-home replacements in waterfront single-family homes with oversize units and structural reframing push toward the high end.
Five variables move your number:
- Opening count and size. Each opening carries fixed costs for permitting, inspection, and mobilization. One large window costs less per square foot than three small ones.
- Existing frame condition. Concrete spalling, corroded steel, or water-damaged wood demands restoration before new units go in. We’ve seen $3,000-$8,000 in unforeseen frame prep on North Beach buildings from the 1960s.
- Structural modifications. Widening an opening requires beam calculation, permit amendment, and often a structural engineer. This adds $1,500-$5,000 and 2-3 weeks.
- Product grade and glazing. Standard NOA-certified aluminum with single-pane laminated is your baseline. Upgrading to insulated laminated, custom color match, or European hardware adds 20-40%.
- Access and protection. High-rise installations, historic district scaffolding requirements, or terrace protection during work add labor and equipment costs.
Our written estimate includes field measure, shop drawings, permit filing, product, installation, sealant, and final inspection. It does not include HOA application fees, structural engineering if required, or interior finish repair beyond standard trim.
Why Miami Beach Changes Everything About This Job
Miami Beach sits on a barrier island barely four feet above sea level, with salt water pressing from both the Atlantic and Biscayne Bay. That geography creates three pressures no mainland contractor automatically anticipates.
First, every window and door must carry Miami-Dade NOA certification for High Velocity Hurricane Zone wind loads. The product list that qualifies is narrower than what you’ll find in Fort Lauderdale or Palm Beach, and “custom” still means “custom within the approved database.” We verify NOA status before presenting any option.
Second, the salt air drives chloride-induced corrosion in concrete, steel, and even some aluminum alloys. In Mid-Beach’s 1950s MiMo buildings and North Beach’s 1960s apartment stock, we routinely find rebar corrosion and concrete delamination around original openings. Cosmetic caulk won’t fix it - we cut back to sound substrate, patch with corrosion-inhibiting repair mortar, and only then install new frames. Skip this step and your new windows leak within two years.
Third, the city’s “Miami Beach Rising Above” infrastructure program has elevated many street grades by one to two feet, especially in South Beach and parts of Mid-Beach. Original entrances and utility connections that were code-compliant a decade ago now sit below street level. When we replace terrace doors or ground-floor windows, we often discover the sill elevation no longer drains properly to the revised streetscape. We resolve this during frame prep, but it adds complexity that doesn’t appear on original as-built drawings.
Historic Preservation Board oversight in the Art Deco district adds another layer. Any visible alteration to window geometry, material, or profile requires board approval, and the board often mandates original stucco profiles and divided-light patterns. “Custom” here sometimes means “custom replication of what existed in 1935.”

Frequently Asked - Custom Windows & Doors in Miami Beach
Most custom windows and doors projects in Miami Beach take 6-12 weeks from contract to final inspection, with permitting and HOA approval consuming the largest variable chunk. Historic Preservation Board review can add 2-4 weeks in South Beach. Call (844) 665-0162 and we’ll estimate your specific timeline based on your building type and location.
Yes - every window and door replacement in Miami Beach requires a building permit, and impact-rated products must carry Miami-Dade NOA certification. Condo and historic district properties need additional HOA or Preservation Board approval. We file all permits and handle inspector scheduling as part of our standard process.
In most cases, yes - window and door replacements use existing rough openings and don’t disturb interior systems. Problems arise only when you’re enlarging an opening or converting a window to a door, which may intersect with concealed conduit or risers. We map this during our initial forensic inspection before you commit to the design.
For pre-1990s Miami Beach housing stock, full replacement is usually the better investment. Original steel and wood windows rarely meet current HVHZ code, and the cost of custom storm panels plus ongoing maintenance typically exceeds replacement within five years. Exceptions exist for Preservation Board-protected properties where original fabric must be retained - we engineer interior storm systems for those cases.
Product warranties vary by manufacturer - typically 10-20 years on frames and glass, 1-5 years on hardware and screens. Our installation workmanship is warranted for the period we specify in your written contract. We don’t bundle these into vague “lifetime” promises; you’ll see exact terms before signing.
