Why Boynton Beach Homeowners Choose Mr-Glass Windows & Doors
We provide independent Mr-Glass windows and doors repair and replacement across Boynton Beach, and we know these products down to the frame joinery and balance systems. If you own a Mr-Glass 8700, 8800, 8400, or 8200, we can diagnose the failure, source the correct part, and fix it without selling you a whole new opening you don’t need. We are not an authorized Mr-Glass dealer and we don’t claim to be. What we are is the shop that sees these windows every week, especially in the older CBS communities along the Intracoastal where salt air and humidity test every seal, roller, and balance.
Dale Kessler has been setting glass in Palm Beach County for decades, and our techs have serviced Mr-Glass products in high-rises, canal-front condos, and the age-restricted communities that make up so much of Boynton Beach. If you need a straight answer about your Mr-Glass windows, call (561) 708-6771.
Why Trust TruePane Windows & Doors for Your Mr-Glass Windows & Doors?
Mr-Glass windows fail in predictable ways, and we know the failure patterns because we’re inside them routinely. The spiral balance on an 8800 double hung loses tension. The glazing bead on an 8700 single hung snaps at the corner. The 8400 roller flattens on the bottom track. The 8200 casement lock rod bends after years of repeated cranking. None of this is guesswork for us. We carry the OEM hardware for the common failures and keep proven aftermarket equivalents for the out-of-production series, matched to the same spring rates and tolerances as the original.
We work on Mr-Glass the way a mechanic works on a familiar engine. Not because we sell the brand, but because Boynton Beach is full of it and someone has to fix it right. Dale grew up in the Meadows section off Lawrence Road, went through the building construction program at Palm Beach State College, and spent the better part of two decades measuring, glazing, and setting frames across Palm Beach County. That background is why we measure every opening twice and why we register both manufacturer warranty layers in writing before the truck leaves your driveway. If it’s not in writing, it’s not a guarantee, it’s a conversation.
We’re background-checked, uniformed, and we answer the phone with a live person every time you call. No voicemail tree. No callback form. You call, a person picks up.
Common Mr-Glass Windows & Doors Problems We Fix in Boynton Beach
- Mr-Glass 8800 Double Hung: Spiral Balance Failure. The spiral balance on the 8800 loses tension over time, especially in Boynton Beach’s salt air, where the internal spring corrodes faster than inland. The sash starts to drop, slam shut, or refuse to stay open. We replace the balance and pivot shoe as a pair, re-tension both sides, and the window holds at any height again.
- Mr-Glass 8700 Single Hung: Cracked Vinyl Glazing Beads. The glazing beads on the 8700 are thin vinyl strips that hold the glass in the sash. After enough thermal cycling and wind flex, they snap at the corners, and the glass starts to rattle. We replace the beads and re-seat the glass. You don’t need a whole new window for this.
- Mr-Glass 8400 Horizontal Roller: Worn Rollers on the Bottom Track. The roller wheels on the 8400 flatten over time, especially when sand and salt grit work into the track. The sash drags, jams, or comes off the rail entirely. We replace the rollers, clean and lubricate the track, and the sash glides again.
- Mr-Glass 8200 Casement: Bent Multi-Point Lock Rods. The 8200 casement uses a multi-point locking rod that runs the length of the sash. Repeated cranking bends the rod, the sash loses alignment, and the window won’t seal. We carry the lock rod hardware and can straighten or replace the mechanism without replacing the sash.
- Blown Insulated Glass Units Across the Mr-Glass Line. When the seal on a dual-pane unit fails, condensation forms between the panes and the window loses its insulating value. In Boynton Beach, seal failure is accelerated by coastal humidity and salt air. If the IGU is blown, we recommend replacement of the glass unit, not a patch job, because no repair restores a failed seal.
Mr-Glass Parts & Our Repair-vs-Replace Approach
We use OEM Mr-Glass balances, rollers, lock hardware, and glazing beads whenever the part is still available. For older Mr-Glass series that have been out of production for years, we source proven aftermarket equivalents that match the original spring rates, dimensions, and tolerances. We don’t substitute cheap generics that fail after a season. If the part is not a proper match, we tell you before we install it.
Here’s our honest rule on repair versus replace. If the frame welds are intact and the failure is a wearable component like a balance, roller, or lock rod, we repair. If the insulated glass unit is blown or the vinyl corner welds are cracked, repair costs climb close to replacement cost, and we recommend replacement instead. We’d rather tell you that upfront than charge you for a repair that won’t last. Call (561) 708-6771 and we’ll give you a straight read on which side of the line your Mr-Glass window falls.
Our Mr-Glass Service Process - Step by Step
- 1
Diagnosis. We inspect the sash, frame, hardware, and track to identify the exact failure. On an 8800 double hung, we check the spiral balance and pivot shoe. On an 8400 horizontal roller, we lift the sash and inspect the roller wheels and track condition.
- 2
Repair or Install. We pull the sash, replace the failed component with the correct OEM or matched aftermarket part, and re-tension or realign everything to the window’s original spec. We measure every opening twice before any new unit goes in.
- 3
Test. We cycle the window through its full range of motion multiple times. The sash should hold at any height, the roller should glide without drag, the lock should seat cleanly. If the pane is not true, the job is not done.
- 4
Warranty. Before we leave, we register both manufacturer warranty layers in writing and confirm your coverage under our Done Right Promise. You get the durations in writing, not a verbal promise.

FAQs - Mr-Glass Windows & Doors Service in Boynton Beach
The spiral balance inside the sash has lost tension, or the pivot shoe has snapped. This is the most common failure we see on the 8800 in Boynton Beach, and it’s accelerated by salt air corroding the balance spring. We replace the balance and pivot shoe as a pair, re-tension both sides, and the window holds at any height again. Call (561) 708-6771 and we’ll confirm the diagnosis.
Yes. The glazing bead is a separate vinyl component that holds the glass into the sash. When it cracks at the corners, we replace the bead and re-seat the glass. There’s no need to replace the sash or the window unless the glass unit itself is blown or the corner welds on the frame are cracked. We stock replacement beads for the 8700 line.
Usually it’s both, but the roller is the primary culprit. The roller wheels flatten over time, and salt and sand from Boynton Beach’s coastal air accelerate the wear. When we service an 8400, we replace the rollers and clean and lubricate the track in the same visit, because replacing the roller without addressing the track only solves half the problem.
Yes. We stock the lock rods and hardware for the 8200 casement multi-point lock mechanism. The rods bend over time from repeated cranking, which throws the sash out of alignment. We can replace the hardware and realign the sash without replacing the entire casement window. If your lock is starting to bind, call (561) 708-6771 before the rod bends far enough to damage the frame.
That depends on the window’s condition and where it is. If the frame welds are intact and the failure is a balance, roller, or lock, repair is usually the right call and costs far less than replacement. If the insulated glass unit is blown or the vinyl corner welds are cracked, we recommend replacement. In Boynton Beach, where wind mitigation inspections control insurance discounts, an older non-impact Mr-Glass window may be worth replacing with an impact-rated unit even if it’s repairable, because the repair won’t satisfy the inspector’s requirements for opening protection.
No. We are an independent Mr-Glass service provider. We’re not an authorized dealer or a factory warranty station. What we offer is hands-on experience with these windows, access to OEM and matched aftermarket parts, and a repair approach that prioritizes the right fix over an upsell. If you need warranty work from Mr-Glass directly, you should contact the manufacturer. If you need an independent shop that knows the product line and can fix it without drama, that’s us.
A balance or pivot shoe replacement on an Mr-Glass 8800 in Boynton Beach typically runs $180 to $340 per sash, depending on whether the parts are OEM or aftermarket and whether both sides need replacement. Roller replacement on an 8400 generally falls in the $120 to $260 range per sash. A full lock rod replacement on an 8200 casement runs $200 to $400 depending on the extent of the misalignment. Blown glass replacement runs $350 to $800 per unit depending on glass type and size. Full impact window replacement runs $700 to $1,500 per opening depending on series, glass package, and frame condition. These are honest ranges, not bids.
