Trusted Window Installation for Coral Gables Homeowners
Window installation in Coral Gables usually costs between $450 and $1,800 per window depending on the style, frame material, and whether you need impact-rated glass for hurricane season. Most single-hung and horizontal roller installs run $450 to $900 per opening, while bay, bow, and garden windows typically land between $1,200 and $4,000. We complete most standard installations in one day per opening, and we’ve been doing this work in Coral Gables since 2011.

What Our Window Installation Service Includes
Single & Double Hung Windows
Single and double hung windows are the most common style in Coral Gables homes, especially in the Riviera and Country Club sections where traditional architecture dominates. A single hung window has a fixed upper sash and a lower sash that slides up, while a double hung lets both sashes move independently for better airflow and easier cleaning from inside the house. We can walk you through both styles with energy-efficient glass packages rated for Florida’s heat and humidity, and we always level the sash tracks so the window opens and closes without sticking after the first year.

Horizontal Roller Windows
Horizontal roller windows slide side to side on a track, and they’re a frequent choice in mid-century Coral Gables homes where wide openings meet smaller budgets. The weak point on any roller window is the track assembly, which is why we pay extra attention to the sill slope and the roller alignment before we set the frame. We also verify the weep holes drain correctly so you don’t get water collecting in the track during a South Florida downpour.

3-Panel Sliding (3-Lite Roller) Windows
3-Panel Sliding (3-Lite Roller) Windows give you a wide view with two fixed lites and one active sliding panel, or configurations that let two panels move depending on the hardware setup. Coral Gables homeowners near the Biltmore Golf Course and along Old Cutler Road often choose these for living rooms and sunrooms where they want light without the expense of a custom picture window. We install 3-lite roller units from major brands and make sure the interlocking stiles seal tight against wind-driven rain.

Casement Windows
Casement Windows crank outward on side hinges and seal against the frame with a compression gasket, which makes them one of the tightest-closing window styles you can install in a coastal climate. They’re a great fit for Coral Gables homes that face east or west and catch heavy afternoon sun, because you can angle the sash to deflect light while still catching a breeze. We install casements with multi-point locking hardware and stainless steel hinges that won’t corrode in salt air.

Awning & Hopper Windows
Awning & Hopper Windows are workhorses in bathrooms, kitchens, and utility rooms across Coral Gables, with awnings hinging at the top to open outward and hoppers hinging at the bottom to tilt inward. The hinged design naturally sheds rain even when the window is partially open, which matters during the six-month stretch when afternoon thunderstorms roll through every other day. We size these windows to your existing rough opening and use insulated glass with a low-E coating that keeps utility rooms from turning into saunas.

Picture & Fixed Windows
Picture windows are fixed in place and built to frame a view, whether that’s a canopy of banyan trees or a pool deck in the Ponce neighborhood. Because they don’t open, the installation has to be absolutely square and properly flashed, or you’ll fight a leak for the life of the window. We set picture windows with a full perimeter seal and continuous sill flashing, and we account for the extra weight of large glass units with structural supports that keep the opening from sagging over time.

Bay & Bow Windows
Bay & Bow Windows project outward from the wall-bays with a center picture window and flanking operable units, bows using four or more panels to create a gentle curve. In Coral Gables, these windows are most common in dining rooms and front sitting areas where the architectural style allows the extra depth. We install bay and bow assemblies as a complete unit with structural supports, roof caps, and insulated seat boards so the projection doesn’t become a condensation or water problem later.

Garden Windows
A garden window is a small, box-like projection with glass on three sides, typically installed over a kitchen sink and used as a shelf for herbs or plants. Coral Gables homeowners love the natural light they bring into older kitchens, especially when paired with a smaller footprint and tempered glass panels. We install garden windows with sloped tops and sealed seams designed for the kind of driving rain we get in June and September.

Brands We Service for Window Installation
We are an authorized installer for CGI and ES Windows, two Florida-based manufacturers whose impact products are built specifically for Miami-Dade and Broward wind codes. Our crews have installed hundreds of CGI windows in Coral Gables over the years, and we understand the frame dimensions, anchoring schedules, and mulling requirements for their fixed and casement lines better than a general contractor ever will. ES Windows builds a sleek, corrosion-resistant aluminum frame that performs well in the salt air near Biscayne Bay and Matheson Hammock.
We also install CWS and ECO Window Systems, both of which offer strong mid-range value for Coral Gables homeowners who want a quality impact product without paying for a legacy brand name. CWS units come with a lifetime limited warranty on the glass and frame components, which gives our clients real confidence on a large investment. ECO Window Systems offers a thinner frame profile that preserves sightlines in older homes where the original window openings weren’t built for bulky impact frames. If you already have a written estimate for any of these brands, window installation in Little Gables is part of our regular service area, and we offer free second opinions on any written bid.

Signs You Need Window Installation Right Now
- Your energy bills have spiked without a change in usage. Single-pane or failed double-pane windows leak conditioned air, and in Coral Gables the air conditioner runs nearly year round. If your FPL bill keeps climbing while your thermostat stays put, the windows are usually the weak point in the envelope.
- You feel a temperature difference near closed windows. Hold your hand near the frame on a hot afternoon. If you feel heat radiating through, the glass or the frame seal has failed. That thermal transfer is why rooms on the south and west sides of your home never cool down as fast as the rest of the house.
- The original windows are single-pane or aluminum framed from the 1960s and 70s. Many Coral Gables homes built before the modern energy codes still carry their original windows. These frames conduct heat directly into the interior, and the glass offers no protection against flying debris in a named storm.
- Windows stick, rattle, or won’t lock properly. Warped sashes and worn hardware aren’t just an inconvenience, they’re a security issue. A window that can’t lock is an open invitation, and a rattling seal means the weatherstripping has failed and water can find a way in.
- You see fog, condensation, or water stains between the glass panes. A fogged unit means the seal has already failed and the insulating gas has escaped. You can’t repair that failure from the outside, and in Coral Gables humidity the moisture trapped inside will only promote mold growth on the frame and surrounding drywall.
Our Window Installation Process - Step by Step
- 1
Measurement and discovery. We start by taking precise measurements of every rough opening, including the depth of the jamb and the condition of the surrounding framing. In older Coral Gables homes we also check for signs of termite damage or rot around the opening before quoting a number, because the last thing you want is a price that’s based on a false premise.
- 2
Written, line-item quote. You get a fixed price on paper, broken down by window, with labor, materials, permits, and haul-away included. This is what we mean by no-hassle upfront pricing: the number you sign is the number you pay, period.
- 3
Permitting and scheduling. Coral Gables has its own building department and permitting process, and we handle the paperwork. Our team pulls the permit, schedules the inspections, and coordinates the install around your availability, not ours.
- 4
Installation and weatherproofing. On install day, the crew protects the work area with drop cloths, removes the old window, and shears and tapes the opening with a self-adhered flashing membrane before setting the new unit. We use closed-cell foam backer rod and high-grade sealant around every frame, then re-trim the interior and exterior as needed.
- 5
Inspection, walkthrough, and cleanup. After the inspector signs off, we walk the project with you, show you how to operate and lock each window, and make sure you’re satisfied before we leave. Every window installation includes our workmanship warranty and the Done Right Promise: if it’s not done right, we make it right.
How Much Does Window Installation Cost in Coral Gables?
A typical single or double hung window installation in Coral Gables runs $450 to $900 per opening, including the new window, labor, flashing, and disposal of the old unit. Horizontal roller windows fall in the same range, while casement and awning windows tend to run $700 to $1,400 because of the added hardware complexity. Picture windows start around $600 for standard sizes and climb to $2,500 or more for oversized glass with tinting or impact ratings. Bay, bow, and garden windows are the priciest category, with most Coral Gables projects landing between $1,200 and $4,000 depending on the projection depth and the manufacturer.
Three things move the price: the brand of window, the condition of the rough opening, and whether the window must meet Miami-Dade impact standards. Impact-rated glass adds 30 to 60 percent to the material cost, but it’s often required by code in Coral Gables depending on the zone and the home’s proximity to the coast. Existing water damage or rotted framing also adds cost, because we won’t install a new window over a compromised opening. A written quote from us includes all of this, so you never get a surprise add-on invoice after the wall is open. Call (904) 478-8983 for a free estimate, and ask about our $40 off any repair over $200 and the permanent 10% discount for seniors and veterans.
