Therma-Tru window installation in Long Beach typically runs $340 – $780 per opening for a full frame replacement, including the new window, weatherproofing, trim work, and haul-away of the old unit. Most homeowners discover they need this service after noticing a sticky sash, condensation trapped between glass panes, or a draft that gets worse every winter. The good news: we keep Therma-Tru-compatible hardware and full replacement units in local supply, so we can usually complete the swap in a single visit.
Which Therma-Tru Models This Applies To
Therma-Tru’s window line divides into two main families: the Kindred Series (vinyl-framed, sized for standard rough openings) and the Heritage Series (heavier extruded frames built for coastal exposure). The compatibility gotcha most Long Beach homeowners run into is this: Kindred windows use a 3¼-inch jamb depth while Heritage frames run 4⅝ inches. If you order the wrong depth, the interior trim won’t sit flush and you’ll see a gap between the casing and the drywall. Look for a white label on the inside of the top jamb, printed with the series name and a manufacturing code starting with “TT.”
On the OEM-versus-aftermarket question: Therma-Tru’s own glass packs and weatherstripping are worth the premium if your window is under five years old, because the brand updates its balance hardware every few years and aftermarket parts don’t always track those changes. For older units outside warranty, quality aftermarket components from manufacturers like Truth Hardware and W.R. Grace sealant systems hold up well enough to justify the savings. We stock both so you can make an informed choice, not just the choice that happens to be on our truck.

Signs Your Therma-Tru Window Installation Is Failing
- Sash tilts when you lift it more than halfway. This points to a worn balance shoe or a broken constant-force coil. On Kindred units, the coil is a 7¾-inch steel strip that loses tension after roughly 8 – 10 years of daily use in Long Beach’s salty air.
- Condensation or haze trapped between the panes. The gas-filled seal has failed. Once argon or krypton escapes, the window’s insulation value drops and the only real fix is a new insulated glass unit, not a repair.
- You hear street noise through a closed window. Older Therma-Tru units used single-strip weatherstripping that compresses over time. When you can hear traffic from Atlantic Avenue through a shut window, that strip has flattened past the point of adjustment.
- The lock no longer lines up. Frames shift subtly over decades, especially in Long Beach’s microclimates where the marine layer keeps wood sub-frames damp. A lock that won’t engage means the sash and frame have drifted out of square.
- The window sticks when the morning fog burns off. Vinyl expands in heat. Heritage Series frames have a metal reinforcement channel that reduces this, but Kindred frames without reinforcement will bind on warm afternoons if the original installer shimmed them too tightly.

AfterReplacement Cost & What’s Included
The installed price range in Long Beach breaks down like this: a basic Kindred double-hung replacement runs $340 – $520 per window. Heritage Series units, with their heavier frames and coastal-rated hardware, land between $560 – $780 per opening. What drives the difference: window size (anything over 36 inches wide adds material cost), whether the interior trim can be reused or needs replacing, and whether the rough opening needs shimming or repair before the new unit goes in.
Every quote we write includes parts, labor, weatherproofing membrane, exterior caulking, interior trim, and removal of the old window. No line item arrives after the fact. We put the price in writing before any work starts, and that number is the number you pay. Every install is covered under our 365-Day Done Right Promise: if the finished work is not right, we make it right.
DIY or Call Us?
There are a few things worth checking yourself before you spend anything. If the window is binding, a little silicone spray on the side tracks of a Kindred unit can restore smooth operation. If the handle feels loose, tightening the two side screws with a Phillips driver often fixes it. Those are safe, five-minute checks.
What we don’t recommend doing yourself is removing the sash to access the balance springs. Coil-type balances are under spring tension, and on Therma-Tru Kindred windows, the coil housing is a sealed unit that releases suddenly when the sash is tilted the wrong way. A slipped spring means a cracked vinyl frame and, in a tight corner, a hand that gets pinched hard. If the glass itself is failed, the handling involved is beyond what most homeowners want to manage. Call us at (562) 912-3327 and we’ll walk you through what you’re seeing before anyone schedules a visit.
FAQs
Expect 20 – 25 years from the frame and hardware, though the glass seal typically needs attention at the 12 – 15 year mark in coastal conditions. The marine layer keeps frames damp and the temperature swings between morning fog and afternoon sun put steady stress on vinyl expansion joints. A properly shimmed installation with correct clearance extends the window’s working life well past the average.
Call (562) 912-3327 and we’ll give you an honest assessment of where your windows sit on their lifespan.
Sometimes, yes. Worn weatherstripping, failed locks, and tilt-latch repairs run $85 – $190 per window and take under an hour. If the insulated glass unit has failed and you’re seeing haze between the panes, a new glass pack runs $210 – $380 installed depending on size. The point where replacement makes more sense is when the frame itself has shifted, rotted, or cracked.
We’ll tell you which route is worth your money, not just the one that costs more.
Most single-window replacements run 2 – 3 hours from setup to final clean-up. A full house of eight to ten windows usually takes two days. We protect the floors with drop cloths before we set up, and you’ll get a photo of the clean-up before the crew pulls away, per our Cedarwell Care Promise.
Our trucks carry Therma-Tru-compatible coil balances, weatherstripping, sweep seals, and lock hardware for both the Kindred and Heritage series. Full replacement windows are ordered per job with current lead times, but common Size 3 and Size 4 double-hungs are available within a week in the Long Beach area. We also stock parts for PGT, CGI, and CWS windows when a home has a mix of brands.
Keith Yamada has been working on windows in the Long Beach area long enough to know that an older house in the Wrigley neighborhood tells you a lot about how it was meant to breathe. He and his crew measure twice before loading the truck, and they don’t rush the walkthrough when the job is done. When the light moves right through a room, the window is doing its job.
