Mr-Glass Windows & Doors in Citrus, CA

Mr-Glass Windows & Doors in Citrus, CA | Juniper Windows West Covina

We provide Window Installation - Citrus and independent Mr-Glass windows and doors service throughout Citrus, CA, from full-frame replacements on mid-century ranch homes to roller rebuilds on original horizontal windows. The work here differs from neighboring cities because so many Citrus houses were built between the 1940s and 1970s with aluminum-frame sliding windows that are now warped, leaking, and out of production. We stock the parts that keep those older Mr-Glass units running, and when a frame is too far gone, we replace it with something that actually performs. Call (350) 305-4609 for a free estimate.

Juniper Windows West Covina is an independent provider. We are not manufacturer-affiliated or authorized by Mr-Glass. That matters because we can recommend honest repairs or replacements without being pushed toward a factory line item. We’ve been doing Mr-Glass sales & service long enough to know which models are worth saving and which ones are better off in the scrap pile.

Why Citrus Residents Choose Us for Mr-Glass Service

Sean Mackey, our owner, learned the trade at Los Angeles Trade-Technical College, where the curriculum drilled building science fundamentals: thermal performance, weatherproofing, and why bad flashing turns into a mold problem three winters later. That background shows up on every Mr-Glass job in Citrus. We don’t just swap glass. We check the rough opening, probe for rot, and size the replacement to the actual frame, not the old glass.

We carry OEM Mr-Glass parts when they’re still produced. For the discontinued stuff, we use high-quality aftermarket balances, rollers, and weatherstripping that match or exceed the original spec. Homeowners in Citrus call us because they’ve already tried the generic route and it didn’t hold up. A Mr-Glass 9500 Series single-hung from 1968 has specific frame tolerances. If the replacement sash doesn’t match, you’ll feel the draft every time the Santa Anas blow through. We get it right because we’ve been measuring these homes for decades.

Common Mr-Glass Windows & Doors Problems We Solve in Citrus

• Warped aluminum sashes on older Mr-Glass single-hung units. Citrus summers run hot and dry, and aluminum expands. After forty or fifty seasons, the sash binds in the track and won’t close tight. During Santa Ana winds, that gap turns into a whistle. We straighten what’s salvageable and replace what isn’t, usually pricing both options so you can decide.
• Failed corner welds on Mr-Glass vinyl double-hung frames. The 5500 Series double-hung is a solid window, but the corner welds on early production runs sometimes split. You’ll notice drafts at the sill corners and condensation on the inside frame during mild Citrus winters. We inspect all four corners before recommending repair versus replacement.
• Worn roller assemblies on Mr-Glass horizontal roller windows. The 7200 Series horizontal roller shows up all over Citrus ranch homes. When the rollers wear flat, the sash drags and groans. We replace the assemblies with upgraded aftermarket rollers that ride smoother than the originals.
• Deteriorated weatherstripping on Mr-Glass sliding patio doors. Fine dust from the San Gabriel foothills finds every gap. If the weatherstripping on your 8200 Series is cracked or collapsed, you’ll see dust trails on the track within a week of cleaning. We replace it with a denser material that seals better under wind load.
• Termite damage hidden behind clean frames. This is the one that surprises people. A Mr-Glass frame can look fine from the outside while the sill underneath is hollow. On Citrus streets with older stucco homes, we always probe before we size a replacement. Skipping that step is how you end up with a new window installed in a compromised opening.

Mr-Glass Service in Citrus: What Local Conditions Mean for Your Equipment

On Citrus streets like Barranca and Azusa, termite damage in window sills is common enough that checking for it has become standard practice for our crew. These are 1950s and 1960s stucco ranch homes, many built on slab foundations with wood framing that sits close to the soil. Termites move up from the ground, eat the sill plate, and leave a hollow shell that still holds paint. The Mr-Glass frame above it can look perfectly square, but the opening underneath is compromised. If you replace the window without fixing the sill, the new frame will rack within a few years. We probe every sill with a screwdriver before we quote a Mr-Glass replacement in Citrus. Generic installers tend to skip that step because it adds time to the job. That’s exactly why we do it.

We were called to a 1962 home on Barranca Avenue with a Mr-Glass 8200 Series aluminum patio door that wouldn’t latch. Once we pulled the frame, we found termite damage in the header and sill. The door had shifted out of square by nearly half an inch. We reinforced the opening, installed a Mr-Glass-compatible full-frame slider with upgraded rollers and weatherstripping, and the owner now reports zero dust infiltration during Santa Anas. That’s the difference between patching and actually fixing.

Mr-Glass Models & Products We Service in Citrus

We cover the full Mr-Glass residential line most common in Citrus homes:

• Mr-Glass 9500 Series Aluminum Single-Hung – the workhorse of 1960s and 1970s ranch builds. We handle sash straightening, balance replacement, and full-frame retrofits.
• Mr-Glass 5500 Series Vinyl Double-Hung – our most requested replacement window for Citrus homeowners moving off original aluminum. Better thermal performance without changing the look.
• Mr-Glass 8200 Series Aluminum Sliding Patio Door – common on back patios. We fix rollers, latches, and weatherstripping, and we replace the full frame when the track is too far gone.
• Mr-Glass 7200 Series Horizontal Roller Window – those wide slider windows you see on stucco ranch houses. We rebuild roller assemblies and replace worn tracks.

For major frame failures or severe racking, we’ll tell you straight when Window Replacement - Citrus makes more sense than patch repairs. We’re not going to sell you a repair that buys you two years when a replacement buys you twenty.

FAQs – Mr-Glass Windows & Doors in Citrus

Can you rebuild the rollers on my original Mr-Glass horizontal roller window in a Citrus ranch home?
Yes. We remove the sash, extract the roller assemblies, and install upgraded aftermarket rollers that fit the original mortise. If the track itself is worn through, we’ll quote a new track as well. Most rebuilds run $180 to $340 per window in Citrus. Call (350) 305-4609 and we’ll confirm what yours needs.

Why does my Mr-Glass sliding patio door leak dust during Santa Ana winds even after replacing the weatherstripping?
Usually the door is out of square. Wind pushes against the panel, and if the header or sill has settled or sagged, the weatherstripping can’t make continuous contact. We check the frame for racking and termite damage before doing anything else. If the frame is square and it still leaks, the weatherstripping profile is wrong for the track. We fix either one and we fix it right.

Are Mr-Glass single-hung aluminum windows from the 1960s worth repairing or should I replace them with vinyl?
Depends on the frame condition. If the aluminum is straight and the track isn’t corroded, a sash straightening and new balances can buy you another decade for a couple hundred dollars. If the frame is warped or the corner welds are failing, replacement is the honest answer. We’ll show you both numbers and you decide. Call (350) 305-4609 for a free assessment.

Do you offer Mr-Glass impact-resistant windows for Citrus homes that face wind-driven debris?
We do. When you’re replacing a Mr-Glass unit and want impact-rated glass, we can source it through our product lines, including PGT and CWS. That’s glass built to resist wind-borne debris without shattering. It also cuts a lot of the solar heat coming through single-pane originals in Citrus summers.

How do you handle termite-damaged sills when replacing Mr-Glass windows in Spanish-style homes on Azusa Avenue?
We probe the sill first, always. If we find damage, we remove the rotten wood, replace it with pressure-treated stock, and tie the new framing into the wall before we set the window. The estimate changes once we can see inside the opening, but we’ll show you photos and explain the added cost before we ask you to approve anything.
