Simonton Bathroom Remodeling: The Los Angeles Owner’s Guide
We install and service Simonton-compatible bathroom remodeling projects throughout Los Angeles, with full bathroom remodels typically running $10,620 to $33,040 installed. Most owners call us when they spot water staining along the sill, a window that’s fogged between the panes, or trouble with a Simonton window in a shower surround that’s no longer sealing out moisture. We keep common Simonton-compatible sashes, balances, weatherstripping, and sill components in stock, and if we don’t have your exact part on the truck, we order it the same day. If you’ve got a Simonton product in your bathroom that’s failed or failing, call (877) 610-1318 and tell us what you’re seeing.
Simonton builds solid windows, but bathroom windows live a harder life than most. Steam, standing water, and temperature swings between shower time and morning cool-down stress seals and hardware faster than any other room in an LA house. We’re an independent contractor, not a Simonton dealer, so we’ll give you a straight answer about whether an OEM part, a quality aftermarket match, or a full replacement makes more sense for your exact window.
Which Simonton Models This Applies To
Simonton has made several series lines over the years, and the right part depends on which one you have. The most common we run across in Los Angeles homes are the Reflections 5500, the Impressions 9800, the ProFinish Contractor series, and the older Madeira windows. Each series uses different balance systems and weatherstripping profiles, so a sash from a Reflections window won’t seat properly in an Impressions frame.
Here’s the compatibility gotcha we see most often: the label matters more than the model name. Look in the header of the window frame, the top inside edge where the sash meets the frame. You’ll find an etched or printed label with a serial number that encodes the window’s glass package and hardware spec. Older Simonton-made windows from before 2015 sometimes have this label on the spacer bar between the panes, not the frame. If you can’t find it, remove the sash and measure the visible glass width and height to the nearest 1/8 inch, and take a photo of the balance shoe. That combination usually gets us to the right match.
OEM versus aftermarket for Simonton comes down to two things: age of the window, and what failed. If your sashes are under warranty and the failure is a seal or hardware defect, the OEM path keeps the warranty intact. If the window is a decade out of warranty, a quality aftermarket balance, shoe, or weatherstrip often costs 30 to 40% less and performs identically. We’ll tell you which way we’d go on our own house.
Signs Your Simonton Bathroom Remodeling Is Failing
- Fogging or condensation between the glass panes. The seal on your insulated glass unit has failed. In a bathroom, warm shower steam accelerates this because the thermal cycling pulls moisture into the gap. The fix is a replacement IGU or full sash, not a wipe-down.
- Water staining or soft drywall under the window sill. The sill dam or the weep holes are clogged or the sealant bead at the frame is shot. In LA’s dry summers this hides, then shows up as a yellow-brown stain after the first winter rain or a run of steamy showers.
- Sticking or jerky sash travel when opening or closing. The balance system is worn. Simonton coil balances lose tension faster in bathrooms because humidity causes the coil housing to corrode slightly over time. If the window slams shut instead of gliding, the balances are done.
- Visible black mold or mildew inside the track or on the weatherstripping. This isn’t just cosmetic. Mold in the track means water is sitting where it shouldn’t, and that weatherstripping is no longer shedding moisture properly. Replacement is cheap; ignoring it isn’t.
- Draft or cold air leaking around the sash edges. Weatherstripping has compressed or torn. In a bathroom window near a tub or shower, draft usually means the frame has shifted slightly or the weatherstrip has hardened from steam exposure.
Replacement Cost & What’s Included
Full Simonton-compatible bathroom remodeling projects in Los Angeles run between $10,620 and $33,040 installed, depending on scope. A small bathroom remodel with a standard window stays at the low end. A full gut including shower glass, tile work, a new Simonton window, and permits lands at the top of that range.

You always get the same breakdown from us: parts at cost, labor in plain numbers, and whatever the permit office charges. No lump-sum mystery. Every change order goes on paper before work resumes. We back every bathroom remodeling job with the written 90-Day Done Right Promise. If something’s not right, one call brings Tom Barrett back, and the inspector’s sign-off is the last word, not ours.
DIY or Call Us?
Some things you can safely check: look for the serial label, note the symptoms, and take photos before calling us. That speeds up the whole conversation and often lets us bring the part on the first trip. You can also clean the weep holes with a bent paperclip and clear any visible debris from the track.
What you shouldn’t do is pull the sash out and start disassembling the balance system. Simonton coil balances are under tension. If they uncoil with your hand in the way, you’re looking at stitches, not a saved service call. Same with removing a fogged IGU: the units are heavy, and once the seal is gone, the glass edges are fragile. Call (877) 610-1318. We’ll come out, match the part, and install it right the first time, or we’ll come back and make it right.
FAQs
In Los Angeles, expect 15 to 25 years from quality Simonton windows in a bathroom, on the lower end if the window sits inside a shower surround or gets daily direct steam. Seals and weatherstripping usually fail before the frame or glass. If yours is showing fog, draft, or stained sills at year 18, you haven’t been robbed. Call (877) 610-1318 for an honest assessment and a firm quote.
Often yes. Bad weatherstripping, worn balances, broken latches, and clogged weep holes are all repairs we do without replacing the whole window. Fogged glass means a new IGU or sash, but the frame stays. Call (877) 610-1318 and describe what’s happening; we’ll tell you if this is a $300 repair or a full replacement before we ever set foot inside.
A single sash, balance, or weatherstrip replacement is usually done in under two hours. A full window replacement inside an existing opening takes half a day, including trim and sealant. A full bathroom remodel with a new Simonton window runs 1 to 3 weeks depending on tile and shower scope. Call (877) 610-1318 to get a written timeline for your specific job.
We keep common balances, shoes, weatherstripping, and latch sets for the Simonton series most often installed in Los Angeles: Reflections 5500, Impressions 9800, ProFinish, and Madeira. If yours isn’t on the shelf, we source it same day or next morning. Call (877) 610-1318 with your serial number or glass measurements and we’ll have the right part the first trip, not the third.
