Mr-Glass Window Replacement: The Fort Lauderdale Owner’s Guide
Mr-Glass window replacement in Fort Lauderdale runs $220 to $680 for most common parts, including labor, with complete sash replacements typically landing between $450 and $900 depending on glass type and frame specs. We stock most Mr-Glass balanced springs, sash locks, tilt latches, and roller assemblies on our service trucks, so a technician can often complete the swap same-day when the diagnosis is straightforward. The way most owners find us: their Mr-Glass window worked fine for eight or nine years, then one morning the sash won’t stay up, or the lock won’t catch, or a sweep has crumbled from ten summers of salt air and afternoon squalls.
We’re an independent service provider, not a Mr-Glass corporate entity, which matters if you need compatible parts fast without waiting on a factory pipeline. Ed Winslow’s name is on the door, so when we say a part fits, we’ve measured it twice.
Which Mr-Glass Models This Applies To
Most Mr-Glass windows in Fort Lauderdale homes fall into three families: single-hung vertical sliders, horizontal sliders, and impact-rated casements, with the first two covering roughly 80% of what we see in the field here along Las Olas, Coral Ridge, and Rio Vista. Your part identification starts with the sash label, which is usually printed on an adhesive tag inside the track or on the top edge of the sash itself. Mr-Glass stamps a series code there, typically starting with MGSH for single-hung or MGHS for horizontal slider, followed by a numeric sequence that encodes the window’s internal build.
The compatibility gotcha: Mr-Glass changed its balance spring profile in the 2018 model year, going from a 5/8-inch coil housing to a narrower 9/16-inch housing, and the two are not interchangeable. If you order the older-style coil by mistake, the sash will bind on the track like a stuck drawer. We keep both profiles on the truck for this exact reason. When a Mr-Glass part is genuinely discontinued, we order quality aftermarket equivalents built to the same track and coil specifications, not universal one-size-fits-none parts that rattle.
Signs Your Mr-Glass Window Replacement Is Failing
- Sash drops when you let go. The balance spring has lost tension or snapped internally. This is the most common Mr-Glass failure in Fort Lauderdale, because coil springs work harder in humid coastal air and simply fatigue after six to ten years of daily use.
- Window sticks partway up or takes real muscle to move. Usually a corroded roller or a swollen nylon track guide. Salt from the ocean accelerates this, and bedroom windows facing east toward the Atlantic tend to fail first.
- Lock won’t catch or the keeper is loose. The sash has shifted slightly out of alignment, often because a roller wore unevenly. Mr-Glass cast locks can also shear at the cam under repeated forced closing.
- Draft or water staining around the sash edge. The weatherstripping or sweep has flattened, and in Fort Lauderdale’s rainy season that means water finds the path of least resistance, which is usually your windowsill.
- Condensation trapped between the panes. The insulated glass unit seal has failed. On impact-rated Mr-Glass units, this also means the structural lamination is aging, and the window should be replaced rather than ignored.
Replacement Cost & What’s Included
Here’s where your money goes on a typical Mr-Glass window replacement in Fort Lauderdale:
- Balance spring replacement (per sash): $90 to $170 installed
- Sash lock and keeper set: $60 to $120 installed
- Tilt latch or guide shoe set: $50 to $110 installed
- Roller assembly pair: $80 to $160 installed
- Weatherstripping and sweep replacement (full window): $70 to $140 installed
- Insulated glass unit replacement (impact-rated): $350 to $900 depending on size and STC needs
The range exists because glass treatment varies wildly: laminated impact glass costs more than annealed, Low-E coatings add cost, and odd-sized sashes above 36 inches wide require custom cutting. Every quote is a written line item, parts and labor split out so you see exactly what you’re paying for. Labor carries the same 36500-Day Done Right Promise as every window we install: if it’s not done right, we come back and fix it. You don’t pay for our mistakes.
DIY or Call Us?
Some things you can absolutely do yourself: cleaning the tracks, tightening a loose keeper screw, and inspecting the sash label to record your series code before calling. That label work genuinely helps us arrive with the right part the first time. What we caution against is diving into a Mr-Glass balance spring swap without the proper carrier tool. The coil is under tension, and a slipped spring can take a chunk out of a finger faster than you can pull your hand back. If the sash is heavy or you’re working above the first floor, just call (904) 913-5886 and let one of our background-checked technicians handle it.
FAQs
In coastal Fort Lauderdale, expect balance springs to last six to ten years, rollers seven to nine, and weatherstripping four to six before the salt air and UV flatten it. Windows on the east and southeast faces, directly exposed to Atlantic weather, fail one to three years sooner than the leeward sides of the house. A quick call to (904) 913-5886 gets you a straight answer on whether to replace a single part or refresh the whole sash.
Some locks and keepers can be re-tightened or re-set, but most Mr-Glass hardware is cast metal and nylon, designed for replacement rather than repair once it fails. We will always tell you if a simple adjustment fixes the problem, because earning your trust matters more than billing a part swap. Call us for an honest assessment, and the estimate is free.
Most single-sash parts go in within 45 minutes once the technician is on site, and if we have the part on the truck, which we usually do for common Mr-Glass series, the whole visit is under an hour. Full insulated glass replacements take longer because the new unit is fabricated to spec, usually three to five business days out. Not sure which category yours falls in? Call (904) 913-5886 and we’ll tell you before anyone gets in the truck.
We stock the most common Mr-Glass balance springs, locks, rollers, and seals on our trucks, and our Fort Lauderdale area runs include restocking stops at our local supplier weekly. If your part is unusual, like an odd-sized impact glass unit or a discontinued 2017-era lock, we source it within three to five business days and let you know the timeline before we start. The fastest way to find out is to call (904) 913-5886 with your sash label numbers in hand.
