Call (562) 912-3327 for a free estimate on any Therma-Tru door or window in your Long Beach home.
Our crew has rebuilt multi-point locks on Classic-Craft doors in Belmont Heights, realigned Smooth-Star slabs in Wrigley, and replaced failed factory edge caps on doors that had been exposed to salt air for a decade. We know these doors the way a mechanic knows a specific model year of a car, and we work throughout the city where the marine layer, historic district rules, and older home framing all intersect. If you need Therma-Tru sales & service, we are the independent shop that shows up with the right parts on the truck.
Why Long Beach Residents Choose Us for Therma-Tru Service
Keith Yamada, our owner, grew up in the San Gabriel Valley where someone on the block was always replacing a window or rescreening a door, and that early attention to old houses carried into formal training at Los Angeles Trade-Technical College. The instruction there was patient and the tolerances were tight, and that is the standard we hold on every Long Beach job. He has worked on older Craftsman and mid-century homes throughout the Wrigley neighborhood, where original frames tell you how a house was meant to breathe, and he measures twice before a crew ever loads the truck.
We are part of the Cedarwell network and have operated under the Cedarwell Care Promise since 2010. That means every job gets a written price before any work starts, no exceptions. Our technicians are background-checked and uniformed, and they follow the C.A.R.E. values on every visit: Clean up like it is our own home, Ask before we move or touch anything, Respect the family’s time and quiet hours, and Explain the price before the work. For Long Beach homeowners with kids and pets, that means shoe covers and drop cloths on every visit, pet-safe sealants wherever a choice exists, and a photo of the clean-up before the crew leaves.

Common Therma-Tru Windows & Doors Problems We Solve in Long Beach
- Delaminating fiberglass skins on Classic-Craft doors. The original polyurethane foam core in early 2000s Classic-Craft units shrinks over time, pulling the fiberglass skin away near the bottom rail. In Long Beach, the salt-laden marine air works its way into that gap and corrodes the internal wooden stile. We remove the skin, inspect the core, and rebuild or replace the affected section.
- Pulse multi-point lock rods losing tension. The control rods on Therma-Tru Pulse hardware are steel, and coastal humidity in Long Beach accelerates surface corrosion that shortens the deadbolt throw. The door feels like it locks, but the bolt catches on the strike plate. We replace the rods with stainless steel and realign all three keeps.
- Smooth-Star edge caps pulling away. The factory adhesive on Smooth-Star fiberglass edge caps breaks down in salt air, especially on doors facing the water in Naples or Belmont Shore. Once the cap separates from the stile, the foam core is exposed to water intrusion, which is how you get swelling and bubbling paint at the bottom corners. We re-bond the caps with a marine-grade adhesive and seal the edge properly.
- Stripped cam screws on adjustable hinges. Therma-Tru’s adjustable hinges are handy during installation, but the cam screws can strip after years of slight settling in Long Beach’s stucco tract homes. That leaves an uneven reveal and poor weatherstrip contact, which means drafty doors and higher humidity inside. We assess whether to replace the hinge, swap to a fixed stainless hinge, or adjust the frame.
- Fogging between glass panes on older Therma-Tru door glass. Persistent fog between the panes means the insulated glass unit seal has failed, not just surface condensation from the marine layer. Salt air is hard on seals. We replace the glass unit and often install fresh corner seal pads at the same time, since those are nearly always original on doors from the 2000s.
Therma-Tru Service in Long Beach: What Local Conditions Mean for Your Equipment
The one thing that separates Long Beach from almost every other city we work in is the combination of historic district oversight and salt air, and no product feels both at once more than a Therma-Tru entry door. In the Bluff Park historic district, any front door visible from the street must be approved by Long Beach’s Cultural Heritage Commission. So when a Bluff Park homeowner needs to replace a rotten 1920s wood entry door, the solution is not a generic fiberglass slab from the supply house. We keep dimensions and profiles of original 1920s doors on file, and we often install a Therma-Tru Classic-Craft fiberglass door with a custom routed panel and a dark stain that reads as original wood from the sidewalk. The commission wants architectural character preserved, and fiberglass survives the salt air far better than the old-growth Douglas fir it replaces. That is the Long Beach-specific reality of working on Therma-Tru doors here: the product has to satisfy both a historic board and a marine climate, and very few shops are set up to do both.
We service everything from high-end Classic-Craft units near the coast to builder-grade Smooth-Star doors on inland tract homes, and the work we do is informed by the specific pressures this city puts on door hardware and seals. For more on where we work, see our Long Beach service area.
Therma-Tru Models & Products We Service in Long Beach
We service the full range of Therma-Tru residential doors and windows in Long Beach: Classic-Craft (including the Mahogany Collection), Fiber-Classic (Mahogany and Oak Collections), Smooth-Star, and the Pulse hardware line that Therma-Tru commonly pairs with these doors. Our parts approach is simple: we install OEM Therma-Tru weatherstripping, corner seal pads, and multi-point keeps because those parts are profiled to match the door’s specific compression set and are still readily available. For hinges and some internal hardware, we use stainless steel aftermarket parts from long-term suppliers when that gets a Long Beach homeowner a faster, more durable repair than waiting on a Therma-Tru shipment.
We also carry full-frame replacement capability for every door line above, including hurricane-proof front and entry doors, and we offer our Window Installation in Long Beach when a full replacement is cheaper than chasing three simultaneous failures in a 15-year-old Coastal Classic-Craft unit.

FAQs – Therma-Tru Windows & Doors in Long Beach
Yes. We rebuild the internal multi-point mechanism in place, including the control rods and keeps. The door stays in the frame. On coastal homes in Long Beach, we use stainless replacement rods because the original steel ones corrode in salt air. Call (562) 912-3327 and we will tell you if your lock is rebuildable or if the cost of a full mechanism replacement approaches a new door.
Usually what you are seeing is not failed fiberglass, but water that got in through a separated edge cap at the bottom rail. The foam core absorbs moisture, swells, and pushes the paint off. We remove the old edge cap, dry and seal the core, and re-bond a new cap with a marine-grade adhesive. Left alone, real delamination follows. Get it looked at sooner rather than later.
Yes. The marine layer puts constant humidity and salt on hardware, even a few blocks from the water. We recommend and install stainless steel hinges, stainless multi-point control rods, and stainless fasteners on every Therma-Tru door we touch in Long Beach. In inland cities like Downey or Cerritos, the standard hardware is fine. Here, it is not a luxury; it is the difference between a door that lasts ten years and one that seizes up in five.
Yes, and it is one of our most common historic-district jobs. We keep profiles and dimensions of original 1920s doors and route the Classic-Craft panel to match. The stain is dark enough to read as original wood from the sidewalk, which is what the Cultural Heritage Commission cares about. You get a fiberglass door that satisfies district approval and never rots in the salt air. Call (562) 912-3327 and we will walk you through the approval process.
If the glass seal has failed, replacement of the insulated glass unit usually costs between $340 and $600. But at 15 years old, that door may also have tired weatherstripping, original corner seal pads, and edge caps near the end of their life. If we see two or more simultaneous failures, we will tell you honestly that a new door is the better long-term play. A new Classic-Craft with full frame starts around $2,400, installed and warrantied. Estimates are free, so there is no cost to find out which path makes sense.
