Sliding & Patio Doors in Boca Del Mar - What to Expect
Sliding and patio door replacement in Boca Del Mar typically runs $4,500-$15,000 depending on size, material grade, and whether the existing frame needs structural modification. Most installations we handle here take 1-3 days once materials arrive, with permits through Palm Beach County adding 10-14 business days to the front end. Call (844) 665-0162 and we’ll walk you through what’s needed for your specific opening.
How We Install Sliding & Patio Doors - Start to Finish
We’ve learned that Boca Del Mar homeowners don’t want us back three times for a job that should take one. Here’s how we structure the work to get it right the first trip.
Stage 1: On-site measure and spec lock (Day 1, 60-90 minutes)
We measure the rough opening, check the existing frame condition, and confirm whether we’re working with original 1970s-80s aluminum framing or a previous replacement. This matters because older CBS homes in Boca Del Mar often have out-of-square openings that need shimming or reframing. You’ll decide on material (vinyl, aluminum, or fiberglass), glass package (standard, Low-E, or impact-rated), and operation style (sliding, French sliding, or multi-slide) at this visit. We photograph the opening and note any electrical or HVAC lines near the header.
Stage 2: Permit pull and material order (Days 2-14)
We file with Palm Beach County Building Division, not Boca Raton - a distinction that trips up contractors who don’t know Boca Del Mar’s unincorporated status. Impact-rated doors or any structural modification triggers a full plan review. Standard like-for-like replacements sometimes qualify for over-the-counter permits. Materials typically ship in 7-10 business days for standard sizes; custom sizes or specialty finishes run 3-4 weeks.
Stage 3: Demo and prep (Day of install, 2-4 hours)
We protect floors and furniture, remove the old door and track system, and expose the rough opening. On older Boca Del Mar homes, we often find corroded fasteners, degraded sill pan flashing, or termite damage in the pressure-treated sill plate. If the header needs reinforcement - common when converting a standard slider to a wider multi-slide - we address it now before the new unit arrives.
Stage 4: Installation and sealing (4-8 hours)
The new unit gets leveled, shimmed, and fastened to structural framing per manufacturer specs. We install new sill pan flashing, apply backer rod and sealant to the exterior perimeter, and insulate the gap with low-expansion foam. For impact-rated installations, we use the specific fastening pattern and anchoring schedule required for Palm Beach County’s wind-load certification.
Stage 5: Trim, hardware, and final inspection (2-3 hours)
Interior trim goes in, hardware gets adjusted for smooth operation, and we clean the glass and track. Palm Beach County requires a final inspection for all permitted door replacements; we schedule it and meet the inspector. You get the manufacturer’s warranty card, our installation warranty documentation, and a walkthrough of operation and maintenance.
The Sliding & Patio Door Options You’ll Actually Choose Between
Most Boca Del Mar homeowners assume a “sliding door” is a single product. It’s not. Here are the real decisions:
- Vinyl frame with standard glass ($4,500-$7,500): Best thermal performance for the dollar, minimal maintenance, but thicker sightlines and limited color options. Suits homeowners prioritizing efficiency over aesthetics, especially for secondary openings facing east or west.
- Aluminum frame with thermal break ($6,500-$10,000): Slimmer profiles, more glass area, wider color and finish selection. The thermal break is non-negotiable in South Florida - without it, the frame sweats and transfers heat aggressively. Costs more than vinyl, looks more refined, lasts longer in salt air.
- Fiberglass frame ($8,500-$13,000): Paintable, extremely durable, thermally stable. The go-to for homeowners who want a specific architectural color match or are replacing wood doors and want the look without the rot risk. Longest lead times, highest material cost.
- Impact-rated vs. standard + shutters ($1,500-$4,000 adder for impact): Palm Beach County requires impact-resistant openings or code-compliant shutters on all replacements. Impact-rated glass eliminates shutter hardware and operation, but adds weight and cost. Standard glass with shutters saves money upfront if you already have functional shutters; many don’t on original 1970s-80s homes.
- Two-panel slider vs. multi-slide or lift-and-slide ($3,000-$8,000 adder): Standard two-panel covers 6-8 feet. Multi-slide systems stack or pocket for 10-20+ foot openings, common when homeowners are opening up a 1970s floor plan to the patio. Requires structural header engineering and significantly more labor.
We source sliding and patio doors from Andersen, Pella, Marvin, Milgard, Jeld-Wen, Simonton, PGT, and CGI - you choose the brand and line that fits your budget and aesthetic, not what’s convenient for us to stock.
What Sliding & Patio Doors Cost in Boca Del Mar, FL
| Scope | Price Range |
|---|---|
| Standard vinyl slider, like-for-like replacement | $4,500-$7,500 |
| Aluminum thermal-break slider, standard size | $6,500-$10,000 |
| Fiberglass or architectural-grade unit | $8,500-$13,000 |
| Multi-slide or lift-and-slide system | $12,000-$15,000+ |
| Structural header modification | $1,500-$4,000 |
| Impact-rated upgrade (glass + frame reinforcement) | $1,500-$4,000 |
Five factors push your job high or low:
1. Existing frame condition. Original 1970s-80s aluminum frames in Boca Del Mar are often corroded at the sill or out of square. Salvaging the frame saves $1,000-$2,000; full rough-opening rebuild adds it back.
2. Size and operation type. A standard 6-foot two-panel slider is straightforward. A 16-foot multi-slide with pocket or stack configuration requires structural engineering, larger crew, and longer install.
3. Impact rating requirement. Palm Beach County’s wind-borne debris code means impact-rated glass or shutters. Impact units cost more but eliminate separate shutter maintenance and operation.
4. Header and structural work. Wider openings need engineered headers, especially in CBS construction where the original header may be inadequate. This triggers additional permit scrutiny and inspection points.
5. Interior and exterior finish repair. Stucco repair on the exterior, drywall or trim repair inside, and flooring transitions aren’t always included in base quotes. We itemize these so you’re not surprised.
Our written estimates specify what’s included - door, frame, hardware, installation, permit fees, and standard trim - and what might add cost based on what we find during demo. Call (844) 665-0162 for an exact quote; estimates are free.
What Boca Del Mar Homes Specifically Do to This Job
Boca Del Mar’s jurisdictional reality catches contractors who don’t do their homework. This is an unincorporated Palm Beach County community - ZIP 33433 - not the City of Boca Raton. File permits with Boca Raton’s building department and you’ll wait two weeks to learn you’re in the wrong system. We pull through Palm Beach County’s Building Division from the start, which means different forms, different inspectors, and different timelines than contractors used to Boca Raton proper.
The housing stock shapes every sliding and patio door job here. These 1970s-80s CBS homes were built with single-pane aluminum sliders that fail in predictable ways: corroded lower tracks that no longer roll smoothly, failed weatherstripping that lets water pool on the tile, and single-pane glass that doesn’t meet current energy or impact codes. When we remove them, we often find the original sill pan flashing was minimal or absent - fine in 1978, unacceptable under current Palm Beach County standards.
The flat and low-slope roofs common in Boca Del Mar create a secondary issue: water finds its way to door headers through degraded roof-to-wall flashing. We’ve opened installations where the header was sound but the top of the rough opening showed chronic moisture intrusion from above. Our crew carries header repair material on every Boca Del Mar job because of this pattern.
HOA architectural review is another variable. Several Boca Del Mar communities require pre-approval of exterior door style, color, and operation type. We build this into our timeline so permit pull doesn’t get ahead of HOA sign-off.

Frequently Asked - Sliding & Patio Doors in Boca Del Mar
Most installations are completed in one to three days once materials are on-site. Standard like-for-like replacements in a 6-8 foot opening typically finish in a single day; multi-slide systems or jobs requiring header modification take two to three. Add 10-14 business days for Palm Beach County permit processing if impact-rated or structural work is involved. Call (844) 665-0162 and we’ll give you a specific timeline for your opening.
Yes - all door replacements in Boca Del Mar require a permit through Palm Beach County Building Division, not Boca Raton’s department. This includes like-for-like replacements. Impact-rated installations or any structural modification trigger additional plan review and inspection requirements. We handle the permit application, scheduling, and inspection meetings as part of our service.
Sometimes. If your existing slider sits under a continuous header with no plumbing or HVAC in the wall above, widening the opening is primarily a structural and framing question. In Boca Del Mar’s 1970s-80s homes, we often find electrical runs or vent stacks in the wall cavity that weren’t originally there - previous renovations added them. We verify with a scope camera during our initial measure before promising anything. If relocation is needed, we coordinate it through our Windows & Doors in Boca Del Mar crew or our full-scope team.
Impact-rated glass is laminated and reinforced to stop wind-borne debris without additional protection; standard glass requires code-compliant shutters or panels that must be deployed before a storm. Impact-rated doors cost $1,500-$4,000 more but eliminate shutter hardware, storage, and the need to install them every hurricane season. Many Boca Del Mar homeowners choose impact-rated when replacing original doors because their existing shutters are aging or missing.
Manufacturer warranties cover the door unit, glass, and hardware - typically 10-20 years for frames and 20 years to lifetime for glass, varying by brand and line. Our installation warranty covers labor and workmanship. We register your warranty with the manufacturer and provide documentation at final walkthrough. Specific terms depend on the brand you select from our portfolio.
