Our Sliding & Patio Doors Services in Margate

Impact Sliding Glass Doors
Every sliding door in Margate must carry a Miami-Dade NOA or Florida Product Approval - the city sits entirely within Broward County’s HVHZ, one of only two Florida counties with that designation. We specify impact-rated units from PGT and Mr-Glass with laminated glass interlayers rated to Margate’s design wind pressure, not generic “hurricane resistant” labels. The measured survey documents the exact design pressure your opening requires, and the written quote locks that specification. No substitutions without a signed change order.

Patio Doors
Margate’s 1960s-1985 CBS homes were built with affordable aluminum-frame sliders, many still in service past their functional life. We replace these with modern units from ViewLux and Therma-Tru, specified by U-factor and SHGC performance rather than what’s in stock. The old track corrosion from Broward’s humidity and driving rain? We see it weekly. The new sill pan and waterproofing detail? Written into the scope before demolition starts.

Sliding Glass Door Replacement
This is where Margate’s housing stock gets specific. In the 1960s CBS tract homes off Royal Palm Boulevard, our crew pulled the original aluminum sliding glass door and found the slab-edge opening had been poured for a jalousie window, not a full-height patio door - the header was undersized, the sill pan had no waterproofing, and the old unit’s track had corroded from years of driving rain. We custom-framed an impact PGT slider with a laminated glass interlayer rated to Margate’s HVHZ design pressure, rebuilt the jamb and sill pan, and pulled the Broward County permit before the first screw went in; the homeowner had a written price for the framing upgrade before we started demolition. That’s standard practice on every replacement we handle in Margate.

Impact French Patio Doors
French patio doors in Margate face the same HVHZ requirements as sliders, with the added complexity of multi-point locking hardware and dual-swing weatherstripping. We source impact-rated French units from PGT and CGI with Miami-Dade NOA documentation, and we size the rough opening to the actual frame dimensions - not the nominal size on the old door. The measured survey catches the discrepancy before the unit is ordered.

AfterTrusted Brands We Service in Margate
We draw from eight verified manufacturer lines - PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux - specified by what the opening requires, not by what is in stock. For Margate’s HVHZ compliance, we lean heavily on PGT and Mr-Glass impact-rated sliders with documented Miami-Dade NOA numbers, and we stock common replacement hardware locally to avoid the lead times that delay out-of-area installers. Every product is matched to the performance tier and price range the customer selects; we don’t upsell margin, we specify performance.
Common Sliding & Patio Doors Problems We See in Margate Homes

- Corroded aluminum tracks from Broward’s humidity and driving afternoon storms. The original sliders in Margate’s 1960s-1980s homes were built with untreated aluminum tracks that pit and seize. The door drags, then the rollers fail, then the frame flexes and leaks at the sill. We measure the track wear during survey and specify stainless-steel or composite replacement hardware where the opening allows.
- Undersized headers and unsealed sill pans in enclosed Florida rooms. These additions were common on Margate’s CBS tract homes, and the slab-edge opening was often poured for jalousie windows - not full-height patio doors. Removing the old frame without inspecting the header and sill pan first is how out-of-area installers create structural and waterproofing failures. We pull the permit and inspect the full opening before quoting the framing allowance.
- Failed wind mitigation inspections due to non-impact sliders. Florida insurers increasingly cancel policies on 1960s-1980s CBS homes whose original single-pane sliders lack Miami-Dade/Broward NOA approvals. A replacement without proper product approval and permit inspection leaves the opening uninspected and the policy exposed. We document every approval number and permit closure for the customer’s insurance file.
- Stucco surround rot from years of sill leakage. Once the track corrodes and the sill seal fails, water migrates behind the stucco and rots the sheathing. We see this at the slab edge in older Margate homes near Margate Boulevard. The repair requires reframing, new weather barrier, and stucco patch - all written into the scope before work starts, with a fixed allowance for hidden damage.
Pricing for Sliding & Patio Doors in Margate, FL
A standard sliding glass door replacement in Margate runs $2,800-$4,200 for a non-impact unit and $3,400-$5,800 for an impact-rated slider with Miami-Dade NOA documentation. Impact French patio doors start around $4,800 and can reach $6,500 for larger openings with multi-point hardware. Screen door installation as a standalone service runs $380-$620.
What moves the price: the condition of the existing frame and header, whether the opening was originally sized for a jalousie window, the need for custom framing to meet HVHZ design pressure, and the permit inspection path through Broward County. We build an allowance for hidden conditions into every contract - typically $400-$900 for framing upgrades - and we price and approve any surprise in writing before touching it. No change orders after demolition starts. That’s Haven Clause 5 (No surprises).

FAQs - Sliding & Patio Doors in Margate

Yes. Broward County requires a permit for every window and door replacement in Margate because the city sits entirely within the High-Velocity Hurricane Zone. The permit triggers an inspection of the full opening, not just the unit, to verify impact rating, installation method, and structural integrity. We pull the permit before the first screw goes in, and the inspection closure documentation goes to your insurance file. Call (754) 254-7558 and we’ll confirm whether your specific opening requires a structural inspection or a standard installation inspection.
Because the slab-edge opening in these rooms was often poured for a jalousie window, not a full-height patio door. The header is undersized, the sill pan lacks waterproofing, and the old frame hides both conditions until demolition starts. Out-of-area installers routinely cut drywall before discovering the problem, then hit the homeowner with a mid-job change order. We inspect the full opening during our measured survey, build a framing allowance into the written quote, and price any upgrade in writing before touching the old frame. Call (754) 254-7558 to schedule that survey.
Every sliding door in Margate must carry a Miami-Dade Notice of Acceptance (NOA) or Florida Product Approval with HVHZ designation. Generic “impact resistant” or “hurricane rated” labels are insufficient for Broward County inspection and will fail a wind mitigation survey. We specify the exact NOA number on your written quote, and we verify it against the Florida Building Commission database before ordering. Call (754) 254-7558 if you want us to review a competitor’s approval documentation.
It can, but only if the product carries the correct Miami-Dade NOA and the installation was permitted and inspected. Florida insurers increasingly require documented impact protection for 1960s-1980s CBS homes, and a non-compliant replacement leaves the policy exposed to mid-term cancellation. We provide the full approval documentation, permit closure, and inspection sign-off for your agent. The wind mitigation inspector will verify the installation method, not just the product label. Call (754) 254-7558 and we’ll explain what your specific insurer typically requires.
A properly specified Low-E impact slider with a low SHGC can reduce solar heat gain through the opening by 40-60% compared to Margate’s original single-pane aluminum units. The exact savings depend on the orientation of the opening, the size of the glass area, and your HVAC system’s efficiency. We specify U-factor and SHGC values on the written quote so you can compare performance, not just price. Call (754) 254-7558 for a measured survey that includes an opening-by-opening performance analysis.
