We stock and install replacement hardware, balances, weatherstripping, and glazing for Mr-Glass windows across Long Beach, with most part-and-labor jobs running between $180 and $650 per window depending on what failed. We carry common Mr-Glass components on our trucks, so a single-window repair is often completed in one two-hour visit. The way most homeowners discover a part has failed is subtle at first: a sash that suddenly takes two hands to lift, a window that drops an inch when you let go, or a draft that wasn’t there last winter. Mr-Glass windows are dependable units, but after years of salt air and sun along the Long Beach coast, the smaller moving parts give out long before the frame ever will.
Which Mr-Glass Models This Applies To
Over the years we’ve serviced the full range of Mr-Glass single-hung, double-hung, horizontal slider, and casement lines that were installed throughout Long Beach neighborhoods like Wrigley, Bixby Knolls, and Belmont Heights. The parts that fail most are surprisingly consistent across models: spiral balances on hung windows, roller assemblies on sliders, and crank mechanisms on casements. If you can find the original label, it’s usually printed on the top edge of the sash or stamped into the metal spacer between the glass panes. That label gives us the series name and sometimes the exact manufacturing date, which matters more than you’d think; Mr-Glass changed balance specifications between certain production years, so we always measure the old part against the new one before we install anything. For most Mr-Glass models we recommend OEM components when they’re available, because the tolerances match exactly. But for older discontinued lines, a quality aftermarket balance or roller from our supplier network is often the only realistic path, and we’ve had excellent results with those as long as the weight rating is correct. Keith Yamada checks this himself before any part goes on the truck: the last thing a homeowner needs is a “universal” balance that isn’t actually universal.
Styles & brands we work with










Signs Your Mr-Glass Window Installation Is Failing
- The sash opens with resistance or won’t stay up. This almost always means a spiral balance or block-and-tackle balance has lost tension or snapped internally. In Long Beach’s coastal humidity, the metal springs inside corrode faster than in drier inland cities like Riverside.
- The window is suddenly drafty along one edge. Weatherstripping and pile seals compress over five to eight years, especially on the west-facing side of a Long Beach house where afternoon sun heats the vinyl and accelerates that flattening. The window itself is fine; the seal just isn’t sealing.
- You hear a scraping or grinding noise when sliding. On Mr-Glass sliders, this is usually a roller that’s gone flat on one side or is dragging over grit it picked up from coastal wind. Left alone, a bad roller will carve a groove into the track and turn a $90 part into a $400 track replacement.
- Condensation or haze between the two panes of glass. That’s a failed insulated glass unit seal. The sash still works, but the thermal performance is gone, and in Long Beach’s ocean-adjacent air you’ll notice it as a window that fogs every morning from May through October.
- A casement crank spins without moving the window. The gear teeth inside the operator have stripped or the arm has bent. This is common on older Mr-Glass casements in the Naples and Belmont Shore areas, where windows get opened and closed repeatedly all summer for the breeze.

AfterReplacement Cost & What’s Included
Here’s honest pricing for Mr-Glass window installation parts and labor in Long Beach right now. What drives the range is whether we’re replacing a single balance versus an entire insulated glass unit, and whether the window is on the ground floor or requires ladder work.
- Spiral balance replacement: $180 – $280 per window, parts and labor
- Slider roller assembly: $190 – $320 per window
- Weatherstripping or pile seal replacement: $150 – $260 per window
- Casement operator and crank: $210 – $370 per window
- Insulated glass unit replacement (seal failure): $350 – $650 per window, depending on size and glass type
Every quote is written, line-by-line, before any work starts. That’s a rule at Lightwell Windows Long Beach, not a courtesy. You’ll see the cost of the part, the cost of labor, and nothing else. If the job takes longer than we estimated, that’s on us – the number on your quote is the number you pay. All replacement work is covered by our 365-Day Done Right Promise: if something isn’t right, we come back and make it right. And like every visit from our crew, you get shoe covers, drop cloths, pet-safe sealants where options exist, and a photo of the cleaned-up work area before we leave.
DIY or Call Us?
There are two parts of a Mr-Glass window you can safely inspect yourself: the visible weatherstripping and the track. If you see cracked or flattened seal material, the fix is straightforward for a patient homeowner. But here’s where we’ve seen DIY go sideways in Long Beach, and I want to be plain about this. Spiral balances are under constant tension. The Mr-Glass versions use a metal rod inside a plastic tube, and when that rod lets go during removal, it can fire out with real force. Roller replacement on a slider usually means lifting the sash out, and a double-pane Mr-Glass sash can weigh over 40 pounds. Drop it once and you’re buying glass, not a roller. If you’re uncertain, call (562) 912-3327 and we’ll give you a straight answer about whether it’s a job a careful homeowner can handle or one that belongs on our truck.
FAQs
In Long Beach’s coastal climate, expect balances and rollers to last seven to twelve years, weatherstripping five to eight years, and a well-made insulated glass unit fifteen to twenty years before seal failure becomes likely. Windows facing west or directly toward the ocean will wear faster. If your window is older than that and acting up, call (562) 912-3327 and we’ll tell you whether it’s a repair or a replacement situation.
Yes, in many cases. A balance with a broken internal spring can sometimes be re-tensioned if caught early, and a slider track with light wear can be reconditioned. But once a balance has snapped, a roller has flat-spotted, or a crank gear has stripped, the component is done and replacement is the honest fix. We always show you the old part so you can see what failed.
Most single-window Mr-Glass part replacements are done in one to two hours on site. An insulated glass unit replacement takes longer because we order the new glass to your exact measurements first, then set a return visit for the install.
We keep common Mr-Glass spiral balances, rollers, and weatherstripping on our trucks, so in most cases we have what we need on the first visit. If your window needs an uncommon balance spec or a custom-sized insulated glass unit, we measure on the first trip, order the part, and install it as soon as it arrives. Lightwell Windows Long Beach is an independent service provider and we carry parts compatible with Mr-Glass windows alongside products from PGT, CGI, and CWS.
