Window Installation in Hobe Sound: Timeline, Process, and What You’ll Pay
Window installation in Hobe Sound typically runs $4,500-$15,000 for a full-home replacement and is usually completed in 2-4 working days, depending on frame condition and whether hurricane-rated products are required. Most homes in the 33455 and 33475 ZIP codes need Martin County permits, which we pull before any work begins.

How we handle window installation from first measure to final inspection
We’ve installed windows across mainland Hobe Sound and the barrier island corridor enough times to know where the job slows down and where it moves fast. Here’s the actual sequence we follow, with what you need to decide at each point.
Stage 1: On-site measure and condition check (1-2 hours, day of scheduling)
We show up, measure every rough opening, and photograph the existing frames, trim, and exterior cladding. On 1960s-1980s ranch homes in mainland Hobe Sound, we’re checking for rotted sill plates, termite damage, and whether the original windows were set with flanges or block frames - that changes how we demo and what flashing kit we spec. You’ll decide at this stage whether you’re matching existing interior trim or replacing it, and whether you want to add or remove a window entirely, which triggers structural review.
Stage 2: Product selection and permit pull (3-10 business days)
This is where you choose frame material, glass package, and operating style. We submit to Martin County Building Department simultaneously. Standard permit turnaround is 5-7 business days for straightforward replacement; longer if you’re in a VE flood zone near the Loxahatchee River or the refuge boundary where elevation certificates get flagged. We handle the submission, the fee, and the scheduling - you just sign off on the product order.
Stage 3: Demo and rough opening prep (half day to full day)
Crew arrives, protects floors and landscaping, removes old units. On coastal homes within a mile of the Atlantic, we often find corroded fasteners and compromised water barriers - salt air does that. We cut back stucco or siding as needed, inspect the sheathing, and replace any rotted framing before the new unit goes in. If we hit structural issues, we stop, photograph, and call you with a change order before proceeding. No surprises.
Stage 4: Install, flash, and seal (1-2 days)
New windows go in level and square, anchored to manufacturer spec, flashed with self-adhering membrane tied into the drainage plane. We foam-insulate the gaps, install exterior trim or integrate with your Windows & Doors in Hobe Sound cladding, and seal everything. Impact-rated units get heavier anchoring and reinforced jambs - that adds time but it’s non-negotiable for HVHZ compliance in this wind zone.
Stage 5: Interior trim, cleanup, and inspection (half day)
Interior casing goes on, we caulk paintable joints, clean glass, haul debris, and walk the job with you. Martin County requires a final inspection for permitted work; we schedule it and meet the inspector. You’re not chasing paperwork.
The window choices that actually change how your home performs
Every option below is a real fork in the road we’ve walked homeowners through on Hobe Sound jobs. No single choice is “best” - it depends on your house, your budget, and how long you plan to stay.
- Vinyl frames - Lowest maintenance, good insulation, price-friendly. The trade-off: color options are limited (usually white or tan), and expansion/contraction in direct coastal sun can stress corner welds over 15+ years. Best for mainland ranch homes where budget matters and the view isn’t the selling point.
- Fiberglass frames - Paintable, thermally stable, stronger than vinyl. Costs 30-50% more but holds up to impact glass weight without sagging. We spec these on custom builds near Jupiter Island where architects are involved and finish color matters.
- Aluminum frames with thermal break - Slim sightlines, maximum glass area, historically popular in mid-century Florida construction. Poor insulator without the thermal break; we only recommend these for non-conditioned spaces or where you’re replicating original aesthetic on a period home.
- Impact-rated vs. non-impact glass - Hobe Sound sits in the High Velocity Hurricane Zone. Impact glass with laminated interlayer eliminates shutter installation and meets code for new or replacement windows in most zones. Adds $200-$400 per opening but removes ongoing shutter cost and labor. Non-impact is still permitted for some interior replacements or where existing shutters are grandfathered.
- Single-hung, double-hung, or fixed picture - Single-hung costs less, double-hung cleans easier from inside, fixed gives the cleanest sightline and best air seal. On Intracoastal-facing homes, we often mix fixed picture windows for views with operable units for ventilation.
- Low-E coating and argon fill - Standard on most glass packages now. The real decision is whether to upgrade to triple-coat Low-E for west-facing walls that take afternoon sun. Pays back faster in Hobe Sound than inland Florida because cooling load dominates.
What window installation costs in Hobe Sound, FL
| Scope | Typical Range |
|---|---|
| Standard window replacement (per opening) | $650-$1,400 |
| Impact-rated window replacement (per opening) | $1,100-$2,200 |
| Full-home window installation (10-15 openings) | $4,500-$15,000 |
| Large picture or architectural window | $2,500-$6,000 |
| Structural modification (widen, add, relocate) | $1,500-$4,500 per opening |
Five factors move you toward the low or high end of these ranges. First, quantity - per-unit pricing drops when we batch 12 windows on one mobilization versus two separate trips for six each. Second, existing frame condition - if we open the wall and find termite-damaged sill or corroded fasteners from salt exposure, remediation adds labor and material. Third, impact rating requirement - the glass, the reinforced frame, and the heavier hardware all cost more, and the installation is slower. Fourth, interior trim - matching 1970s ranch casing or upgrading to Craftsman-style buildup changes finish carpentry hours. Fifth, access difficulty - second-story units over coral rock landscaping, common on older Hobe Sound homes, require scaffolding or mini-lifts that first-floor replacements don’t.
Our written estimate includes windows, freight, demo, disposal, installation, flashing, basic interior trim, permit fees, and final inspection coordination. It does not include exterior siding repair beyond the window perimeter, interior painting, or window treatments. If your home needs structural repair or flood-vent relocation tied to the window work, we line-item that separately so you see where the money goes.
Why Hobe Sound homes make window installation different
The mainland side of Hobe Sound, ZIP 33455, is full of 1960s-1980s Florida ranch homes with original aluminum single-hung windows - the kind with no thermal break, no impact rating, and frames that have been baking in salt air for forty years. We regularly open walls on these jobs and find the original nailing flanges corroded through, or sill plates punky from decades of condensation runoff. It’s not just a window swap; it’s often a mini-restoration of the opening itself.
Then there’s the regulatory layer. Martin County’s slow-growth posture means our windows & doors crew works with building officials who know the local flood maps cold. Homes near the Hobe Sound National Wildlife Refuge boundary or the Loxahatchee River corridor often sit in AE or VE zones where elevation certificates trigger additional scrutiny. We’ve seen contractors from Palm Beach County get stop-work orders because they didn’t account for buffer setbacks that don’t exist where they usually work. We know the inspectors by name, we know which plans examiners flag hurricane strapping on older ranches, and we submit complete packages the first time.
On the barrier island side, the build era skews newer and the spec skews luxury - but the wind load doesn’t relax. Impact-rated envelope assemblies are standard, and HOA architectural review boards (especially in Jupiter Island-adjacent communities) often require specific sightlines, finish colors, or divided-light patterns. We submit product cut sheets and finish samples as part of our standard package so you’re not chasing approvals after install.
Salt-air corrosion is the hidden maintenance driver here. Fasteners, flashing, and metal connectors within a mile of the Atlantic or Intracoastal fail faster than inland Florida. We spec stainless or polymer-modified flashing on coastal jobs, not standard aluminum - it costs more upfront, but we’ve been called back to other contractors’ jobs where cheap flashing turned to lace in seven years.
Homeowners doing full exterior updates often pair window work with Wood Fence in Hobe Sound or Chain Link Fence in Hobe Sound to complete the envelope in one mobilization. We coordinate both trades under one schedule so you’re not managing multiple crews.

Frequently asked - Window Installation in Hobe Sound
Most full-home window installations finish in 2-4 working days once materials arrive. Permits add 5-10 calendar days upfront, and custom or impact-rated products can stretch lead times to 4-6 weeks. We schedule demo only after product is in-hand so you’re not living with open walls. Call (844) 665-0162 and we’ll give you a firm timeline based on your product choice.
Yes, Martin County requires permits for all window replacements that change the opening or involve impact-rated products. We pull the permit, pay the fee, and schedule inspections as part of our standard scope. The only exception is direct in-kind replacement of a single non-impact unit in an existing opening on a non-flood-zone home - and even then, we verify with the building department before skipping it.
Almost always, yes. Standard window replacement keeps the same rough opening, so no plumbing or electrical relocation is needed. If you want to widen a window, add one, or move it to a different wall, we flag that during measure and bring in our structural reviewer. We’ll tell you before you sign anything whether your plan triggers MEP relocation.
For original 1960s-1980s aluminum windows, replacement is usually the better investment. Repairing corroded frames, failed seals, and non-impact glass runs $300-$600 per unit and leaves you with the same thermal performance and hurricane vulnerability. New vinyl or fiberglass units with modern glass packages cut cooling load and eliminate shutter hassle. We only recommend repair when the window is historically significant or part of a protected structure.
Product warranties vary by manufacturer - typically 20 years to lifetime on glass seal failure, 10 years on hardware, with frame coverage in between. Our installation workmanship is warrantied for the period we specify in your written contract, covering leaks due to installation error, operational defects, and trim separation. We register your product warranty with the manufacturer so you’re not chasing paperwork if you sell the home.
