Our team provides retrofit inserts and full-frame tear-outs, delivering dry sills for homes and slim modern sightlines for both residential and commercial projects. Thirteen years in business and a 2-year workmanship warranty on every installation stand behind more than 1,730 completed projects, from a pair of pitted bedroom sliders to a 48-window condominium elevation.
From clearing plugged weep holes in a corroded track to sealing a new sill pan under a stucco opening, our team handles every detail. Serving Carlsbad and neighboring Solana Beach, Poway and Encinitas, we pull the old metal out one room at a time so the house is closed up before dark.

Bluff-top condominium association replacing every original slider on the ocean elevation at once

Ellen's association replaced every original aluminum slider on its ocean elevation at once: 48 windows across 12 units in the bluff-top condominiums of Solana Beach. We recommended white vinyl sliders with dual-pane Low-E glass, one color and grid spec the board approved, and we phased the units two a day with notices to residents. The job was an estimated $41,000 to $58,000 over an estimated 7 to 11 days. The result is one matching elevation, every unit signed off, and no resident out of their home overnight.

Pick a window style, then switch the frame from aluminum to vinyl, fiberglass or wood to see the estimated price per window, the usual lifespan and the warranty each one carries. Owners in Calavera Hills and Bressi Ranch usually land on vinyl for budget, while fiberglass wins closer to the water in Leucadia.

Aluminum windows are done when the frame sweats, the track pits and the sill stays wet, and in coastal North County all three usually show up together. Mill-finish aluminum conducts heat straight through, so on a cool marine layer morning the inside of the frame runs with condensation that drips onto the sill and the drywall below it.
Salt air does the rest. The bare metal near Carlsbad Village and Cardiff-by-the-Sea pits into a white crust, the steel rollers grind on a rough track, and the weep holes that should drain the channel plug with grit, so rain sits in the track and finds its way inside.
Roughly one in five Carlsbad homes dates to the 1970s and another quarter to the 1980s, which is exactly the era of the builder aluminum slider.
Vinyl is the lowest-cost replacement for old aluminum, fiberglass lasts longest in salt air, and modern thermally broken aluminum is the pick when the thinnest frame matters more than the price.
| Frame | Est. price per window | Typical lifespan | Typical warranty | Best fit near Carlsbad |
|---|---|---|---|---|
| Vinyl | Est. $350 to $800 | 20 to 35 years | 20 years to Limited Lifetime | Inland tracts in Old Poway and New Encinitas |
| Fiberglass | Est. $400 to $1,500 | 35 to 50 years | 20 years to Limited Lifetime | Homes within sight of the water in Leucadia |
| Thermally broken aluminum | Est. $200 to $800 | 25 to 40 years | 10 to 20 years | Modern homes in Del Mar Heights wanting thin sightlines |
A thermal break is a strip of insulating material that splits the aluminum into an inside and an outside half, which is what stops the sweating that old one-piece frames in Rancho Santa Fe Village and Harmony Grove Village are known for.
Thermally broken aluminum is the right replacement when a modern or mid-century home needs very slim frames and large glass, because aluminum stays rigid in a narrow profile that vinyl cannot match. We specify it with a powder-coated or anodized finish for Old Del Mar and Eden Gardens homes, and we keep the old mill-finish look off the list entirely.
Replacing an old aluminum window in Carlsbad is estimated at roughly $450 to $1,500 per opening, and the install method, the new frame material and the condition of the sill move the price most. A retrofit vinyl insert in a sound frame sits at the low end, while a fiberglass unit set after a full-frame tear-out with a stucco patch lands near the top.
Volume changes the math. A single-story home with 10 to 15 aluminum windows is typically estimated at $8,500 to $12,000, and Ellen's 48-window association job shows how one spec across many units keeps the per-window figure in check.
These figures are estimates for Carlsbad homes and may change once we inspect each frame and sill. The written quote after your measure sets the final price and the install schedule.
Each old aluminum frame gets one call before ordering: a flat, square, dry frame hosts an insert, and a pitted or leaking one comes out to the studs. Our measure tech checks every frame from La Costa to Olivenhain, and a retrofit insert in a sound frame, the method on our retrofit window installation page, leaves the stucco untouched.
The common mistake is sliding an insert into a frame that is already corroded or leaking at the sill, which buries the problem behind new trim. The second is skipping the permit: Title 24 applies to a like-for-like swap in Carlsbad, so the NFRC label stays on each new window until the inspector signs off. Homes built before 1978 also get lead-safe containment when the old paint around the frame is disturbed.
Most aluminum swaps land on one of two frames: vinyl windows sized to the old openings for value, or salt-air fiberglass frames for homes near the bluffs. Both come dual-pane Low-E with argon fill by default, with a U-Factor of 0.25 to 0.28 typical, and both stop the frame from sweating in Fairbanks Ranch and Del Mar alike.
The crew that measures your aluminum windows is the crew that removes them, so the opening sizes are never a second-hand guess. Every installation carries our 2-year workmanship warranty, and the maker's warranty typically adds 20 years on the glass and 10 years on non-glass parts, so meet the team before your measure.
We replace aluminum windows across a 30-mile radius of Carlsbad, including bluff-top homes in Solana Beach, 1970s tracts in Poway and coastal cottages in Encinitas. Del Mar, Bonsall, Lake San Marcos and Harmony Grove are on our full list of cities.
When every aluminum opening goes at once, our full window replacement page covers the whole-house schedule, and owners whose metal frames hold single-pane glass can read about swapping single-pane for dual-pane. Sound frames can also take a pocket insert instead of a tear-out.
A retrofit vinyl window replacing old aluminum is typically estimated at $450 to $950, a slider at $750 to $1,400, and your written quote sets the final figure.
Old aluminum frames sweat because the metal carries outdoor cold straight to the room side, and moist indoor air condenses on it, most of all on marine layer mornings.
Yes, when the frame is flat, square and not corroded through, a retrofit insert fits inside it; a pitted or leaking frame comes out instead.
Vinyl insulates far better than single-pane mill-finish aluminum and costs less than most frames, while thermally broken aluminum stays the choice for very slim modern sightlines.
Most slider swaps typically take 1 to 2 hours per window, so a single-story home in La Costa is usually done in an estimated 1 to 2 days.
Yes, Title 24 permits apply to replacement windows in Carlsbad, and our crew lead files the permit and meets the inspector.
Not on a retrofit, which leaves the stucco alone, while a full-frame tear-out gets a stucco patch and new flashing around the opening.

The process
We check every frame, sill and the stucco around it, then laser-measure each opening for the unit that goes in it.
Frame material, glass package, label values and install method arrive in writing before anything is ordered.
Each window is set on a sloped sill pan, flashed and sealed, with the NFRC sticker left on for the inspector.
We open and lock every window and door with you, and the city signs off the Title 24 permit.
