Therma-Tru Construction in Los Angeles, CA | Penhallow Remodeling Los Angeles

We provide independent Therma-Tru door and window service across Los Angeles, handling everything from warped slab replacement to full frame re-hangs on hillside homes. What makes our work different here is simple: we account for the seismic retrofit realities, foundation settlement, and intense UV exposure that flatland contractors never see. If you need Therma-Tru sales & service from a crew that understands Los Angeles construction, call (213) 277-6578 for a free estimate.

Why Los Angeles Residents Choose Us for Therma-Tru Service

Trevor Nash, our owner, grew up in the Crenshaw district watching his uncle re-frame doorways in the old bungalows nearby. That’s where the habit started: give you a number first, then pick up the tools. He studied construction technology at Los Angeles Trade-Technical College and has spent the better part of two decades working residential and light commercial jobs across the Basin. Our crews carry that same standard into every Therma-Tru service call. We’re on time, we’re uniformed, and we put a written price in your hand before any work begins. That’s the Kingswell Way, and it’s been the operating standard since 2004. Every job also comes with our 365-Day Done Right Promise in writing: if something fails inside the guarantee period, we come back and fix it at no charge.

Common Therma-Tru Construction Problems We Solve in Los Angeles

  • Warped or sagging fiberglass slabs from direct sun. West-facing entries in Sherman Oaks and Woodland Hills take brutal afternoon UV. After enough years, the slab bows and the latch binds. We replace with a new Therma-Tru slab, re-hung square, and often add an extended drip cap to reduce future exposure.
  • Failed perimeter weatherstripping and worn door sweeps. When Santa Ana winds push through, dust and grit blow straight past compressed seals. We install aftermarket weatherstripping that often exceeds factory specs at a lower cost, then adjust the sweep so the threshold stops whistling.
  • Deteriorated bottom rails from irrigation overspray. Landscaped front entries in Los Angeles mean sprinkler heads aimed at the door. Water wicks up into the bottom rail and rots it from the inside. We replace with Therma-Tru’s rot-resistant composite bottom rail and re-set the weatherseal.
  • Loose or stripped hinge screws in stucco or wood-framed jambs. Older Los Angeles homes have jambs that have been re-screwed too many times. The door sags, the deadbolt misses the strike plate, and security suffers. We bore out the stripped holes, epoxy in hardwood dowels, and re-hang with longer screws that bite into the rough opening framing.
  • Out-of-square installations from hillside settlement. Echo Park and Silver Lake homes shift. That means Therma-Tru doors installed years ago are no longer square. We shim the jamb, adjust hinge placement, and sometimes use longer hinges to compensate for the movement without tearing out the frame.

Therma-Tru Service in Los Angeles: What Local Conditions Mean for Your Equipment

Many pre-1980 Los Angeles homes were built with single-width door frames and no door overhangs at all. That’s why Therma-Tru’s Fiber-Classic series is the most common replacement we install: its composite edge design handles direct sun and rain without the swelling that plagues wood doors. Up in hillside areas like Echo Park, we regularly find Therma-Tru doors installed out of square because the foundation has settled over the decades. That requires custom jamb shimming and, in some cases, longer hinges you would never need on a flatland tract home in the Valley. The house moves; the door has to move with it. Spend enough time working on Los Angeles hillsides and you learn to check for settlement before you ever measure the slab.

Therma-Tru Models & Products We Service in Los Angeles

We work on the full Therma-Tru lineup: Fiber-Classic entry doors, Smooth-Star doors, Pulse series doors, and Benchmark by Therma-Tru doors. Our approach on parts is straightforward. For structural components like slabs, frames, and hardware, we use genuine Therma-Tru OEM parts when a like-for-like replacement preserves the door’s engineered performance. For weatherstripping, sweeps, and non-structural trim, we often recommend aftermarket parts that beat factory specs for less money. We stock common sill caps, sweeps, and hinge kits on the truck, which means most Los Angeles service calls don’t require a second trip or a week waiting on a shipment.

Therma-Tru Service Pricing in Los Angeles

Door slab replacement with re-hang and weatherseal on a Therma-Tru opening typically runs $2,950 to $5,900. Window replacement using Therma-Tru compatible flanges runs $5,310 to $17,700 per opening, depending on size, glass package, and whether the existing frame can be salvaged. What drives the number: access (hillside homes with retaining walls cost more to stage), the condition of the rough opening, and whether we’re reusing your existing frame or replacing it. Every estimate is free and written in full before work begins. Call (213) 277-6578 and we’ll put a number in your hand.

Service Price Range
Door slab replacement with re-hang and weatherseal $2,950 – $5,900
