How We Handle Door Installation - Start to Finish
Every door installation we do in Hobe Sound follows five stages. Here’s what happens, how long each takes, and what you’ll need to decide.
Stage 1: Site measure and condition check (30-60 minutes on-site)
We show up with a laser measure and a moisture meter. In Hobe Sound, we’re especially watchful for salt-air corrosion on exterior fasteners and rot in the subfloor near Intracoastal-facing entries. We’ll check whether your existing frame is plumb - many 1960s-80s ranch homes in the 33455 mainland have settled slightly, and a new prehung door won’t sit right without shimming or reframing. You’ll decide at this stage: prehung unit (new frame included) or slab-only replacement (reuses existing frame if it’s sound).
Stage 2: Product selection and ordering (same day to 2 weeks lead time)
We spec your door based on exposure, code requirements, and your preference. For homes within a mile of the Atlantic or the Intracoastal, we typically recommend fiberglass or steel over wood due to salt-air durability. Impact-rated options carry longer lead times - sometimes 2-3 weeks - because they must pass Miami-Dade HVHZ certification even though Hobe Sound sits in Martin County. You’ll choose: material (fiberglass, steel, wood, or aluminum-clad), impact rating (if required by your zone), hardware finish, and whether you want sidelights or transom glass.
Stage 3: Demo and rough opening prep (2-4 hours per door)
We remove the old unit, inspect the rough opening for water damage, and replace any compromised framing as part of our Fence Repair service in Hobe Sound and related exterior work. In flood-zone homes near the Loxahatchee River, we often find prior water intrusion that wasn’t visible from the interior. If your home lacks hurricane strapping at the door header - common in pre-1990s construction - we’ll flag it and quote the tie-down upgrade separately. This is where the job timeline can extend if structural repairs are needed.
Stage 4: Installation and weatherproofing (2-5 hours per door)
We set the new door plumb and level, shim with composite wedges (never wood, which rots), and secure with long screws into the king studs. Flashing tape goes on in shingle-style sequence: sill pan first, then jambs, then head flashing. We use low-expansion foam for insulation, not fiberglass batt, because it seals against air infiltration and doesn’t compress. Final step is hardware installation and operational testing - three full open/close cycles, latch engagement check, and deadbolt alignment.
Stage 5: Trim, paint, and final walkthrough (1-2 hours)
Interior and exterior trim goes on last. We use PVC trim on coastal-exposed doors and primed finger-joint pine inland. You’ll do a final walkthrough with our crew lead, and we leave you with the manufacturer’s warranty card and our installation warranty documentation.
The Door Options You’ll Actually Choose Between
Most homeowners we meet in Hobe Sound think they’re picking a color and a style. The real decisions run deeper. Here’s what moves the needle on performance and price:
- Fiberglass entry doors ($600-$1,400 unit cost): Best all-around value for coastal Florida. Resists denting, won’t rot, and modern grain textures mimic wood convincingly. The downside: deep scratches are harder to repair than steel, and premium grain finishes add $200-$400.
- Steel entry doors ($400-$1,000 unit cost): Strongest security, lowest price, excellent for rental properties or secondary entries. Dents permanently, though, and salt-air corrosion is a real issue within five years if the factory finish gets compromised. We don’t recommend steel for direct oceanfront without a storm door.
- Solid wood doors ($1,200-$3,500+ unit cost): Unmatched aesthetic, especially for custom homes in the Jupiter Island corridor. Requires diligent maintenance - refinishing every 2-3 years in Hobe Sound’s UV and humidity. We spec only mahogany or teak for exterior use; pine and fir fail too quickly here.
- Impact-rated doors (add $400-$900 to base material cost): Required in HVHZ zones and strongly recommended for any home east of U.S. 1. These are laminated glass assemblies with reinforced frames - not just “heavy doors.” The peace of mind during hurricane season is real, but the weight means your hinges and closer hardware must be upgraded too.
- Prehung vs. slab replacement: Prehung units cost more upfront ($150-$300 additional) but save labor if your frame is compromised. Slab-only makes sense only when the existing frame is plumb, square, and structurally sound - rare in homes built before 1985.
What Door Installation Costs in Hobe Sound, FL
For a standard residential door installation in Hobe Sound, expect to pay between $450 and $1,800 per opening. Most single prehung fiberglass replacements with basic hardware fall in the $650-$1,100 range. Here’s what pushes you toward the low or high end:
| Cost Factor | Low-End Scenario | High-End Scenario |
|---|---|---|
| Existing condition | Sound frame, no rot, standard rough opening | Frame replacement, header repair, structural shimming |
| Material grade | Steel slab, basic lockset | Impact-rated fiberglass with multipoint hardware |
| Size / configuration | Single 32″ or 36″ x 80″ | Double door, sidelights, transom, or custom height |
| Permit scope | Like-for-like replacement, no permit | Structural modification, impact upgrade, flood-vent integration |
| Location / access | Ground floor, easy truck access | Elevated foundation, tight setback, barrier island delivery |
What’s included in our written estimate: door unit, hardware, labor, weatherstripping, flashing materials, debris removal, and our installation warranty. What’s typically separate: permit fees (if required), structural repairs discovered during demo, interior or exterior paint/finish, and smart lock upgrades beyond standard deadbolt prep.

What Hobe Sound Homes Specifically Do to This Job
Our Hobe Sound service area sits entirely within Martin County, which has among the most restrictive growth management and coastal construction regulations in Florida. Contractors working here must navigate Martin County’s Coastal Construction Control Line setbacks, environmental buffers tied to the Hobe Sound National Wildlife Refuge, and Loxahatchee River-adjacent flood zone requirements that simply do not apply just across the county line in Jupiter or Palm Beach Gardens. For door installation, this matters in three concrete ways.
First, any door replacement on a home east of U.S. 1 or within designated AE/VE flood zones must maintain or improve the structure’s flood-vent compliance. If your existing door sits on an elevated foundation with flood vents beneath, we can’t drop the threshold height or block vent openings without triggering a full floodplain engineering review. We’ve seen homeowners get halfway through a “simple” door swap before the county flagged the threshold change.
Second, the housing stock itself drives our approach. The mainland side in 33455 mixes mid-century Florida ranch homes from the 1960s-80s with newer infill custom builds. Those older structures commonly lack modern hurricane strapping and require full tie-down upgrades when permitted for remodel. We regularly open walls in 1970s ranches near Bridge Road to find no header strapping at all - just toenailed framing that won’t pass current inspection. It’s not a dealbreaker, but it’s a $400-$800 add that should be in your budget from the start, not a surprise on day two.
Third, Martin County’s Development Review Committee enforces environmental buffer rules tied to gopher tortoise habitat and wildlife refuge adjacency. While this more commonly affects ground-disturbing work, we’ve seen stop-work orders on whole-home renovations where door installation was just one piece - because the county’s review flagged the broader project for buffer encroachment. We check parcel maps before we quote any job near the refuge boundary on the north end of town.
And the salt air is real. Homes within a mile of the water - whether Atlantic or Intracoastal - show accelerated fastener corrosion we simply don’t see in Tequesta or Palm Beach Gardens. We spec stainless or ceramic-coated hardware as standard on coastal installs, not as an upsell.

Frequently Asked - Door Installation in Hobe Sound
Most single door installations in Hobe Sound are completed in one day. Full-home retrofits with multiple units, impact-rated upgrades, or jobs requiring structural reframing typically run 2-3 days. Call (844) 665-0162 and we’ll give you a firm timeline after seeing your specific openings.
Like-for-like replacement of an existing door usually does not require a permit in Martin County. Any structural modification, impact-rated upgrade in a designated zone, or threshold change in a flood zone does require permitting. We pull permits when needed and handle the inspection scheduling - it’s part of our scope, not yours to manage.
In nearly all cases, yes. Door installation rarely intersects with plumbing or electrical systems unless you’re relocating the opening itself or converting a window to a door. For standard replacement, the rough opening stays put and utilities stay untouched. We’ll confirm this during our initial measure.
A steel slab replacement using your existing frame runs toward the low end of our $450-$1,800 range, typically $450-$700. The honest trade-off: shorter lifespan in coastal conditions and no impact rating. For most Hobe Sound homeowners, we recommend spending the extra $200-$400 for fiberglass - it pays back in durability and energy performance.
We warranty our installation workmanship, and the door itself carries the manufacturer’s warranty - typically limited lifetime on fiberglass and steel doors from major brands, 1-5 years on wood depending on the line. We register your warranty and leave you the documentation. Specific terms vary by product; we’ll show you the exact coverage before you order.
