Mr-Glass Windows & Doors: The Redwood City Owner’s Guide
We stock and install Mr-Glass-compatible windows and doors in Redwood City, with most replacement projects running $4,500-$15,000 for window replacement and $8,000-$25,000 for impact window installation depending on series and opening count. Most standard sash, hinge, and lock hardware is on our trucks, and we can typically inspect and quote within 48 hours. Homeowners usually discover a problem when a window won’t stay open, a door drags on the threshold, or they notice visible moisture between panes on the foggy mornings common to Redwood City’s bay-side microclimate.
Which Mr-Glass Models This Applies To
Mr-Glass produces several window and door series, and the part you need depends on the generation. Look for the etched manufacturing date and series code in the lower corner of the glass or on the hinge stile of operable units - pre-2018 units often used a different cam lock geometry than current production. The 5000 Series vinyl double-hung and 7000 Series casement are the most common in Redwood City, particularly in the Stambaugh-Heller neighborhood where we’ve replaced dozens of original units in 1920s craftsman renovations. The 8000 Series impact-rated line, required in some FEMA flood-zone properties near Redwood Creek, uses heavier-duty balances and reinforced jambs that are not interchangeable with standard series hardware.
We source OEM Mr-Glass parts where they’re still manufactured, but we’ve also vetted aftermarket equivalents from Truth Hardware and Amesbury for certain discontinued balances and tilt latches. The aftermarket route saves 15-30% on parts cost and carries the same 365-Day Done Right Promise on the installation. For units still under Mr-Glass’s original warranty, OEM is usually required to preserve coverage - we’ll check that before ordering.
Signs Your Mr-Glass Windows & Doors Is Failing

- Sash won’t stay open or slams shut. The coil balance or block-and-tackle system has lost tension. In Redwood City’s salt-air environment, balance springs corrode faster than inland markets - we see this most on south-facing elevations within five miles of the bay.
- Visible moisture or fog between glass panes. The insulated glass unit (IGU) seal has failed, allowing condensation inside the airspace. Once the desiccant saturates, the clouding becomes permanent and the thermal performance drops measurably.
- Door sticks, drags, or won’t latch without lifting. Hinge screws have backed out or the frame has settled; sometimes the multi-point lock mechanism has worn where the deadbolt engages the keep. The underlying cause determines whether it’s a $40 part or a $400 reframing.
- Draft around the perimeter even when closed. Compression weatherstrip has flattened or the bulb seal has torn at the corners. Mr-Glass uses a proprietary fin-seal on some series that must be matched exactly - generic pile weatherstrip won’t seal the same profile.
- Crank handle spins without moving the sash. The casement operator gearbox has stripped, usually from over-torquing or corrosion in the linkage arms. The operator and arm assembly often need replacement as a matched set.

AfterReplacement Cost & What’s Included
For Mr-Glass window replacement in Redwood City, our installed pricing runs $4,500-$15,000 for standard replacement and $8,000-$25,000 for impact-rated installation, with the spread driven by opening count, series selection, and whether the original frames are retrofit or full-frame replacement. Single-part repairs - a balance, lock, or IGU swap - typically fall in the $400-$1,800 range depending on access and whether the sash needs removal.
Every quote is a flat written price with line-item parts and labor before work starts, under Clause 1 of the Haven Standard. We pull permits when required by Redwood City’s building division, and every visit includes a documented photo record of the condition we found and what we installed. Our 365-Day Done Right Promise covers the installation and workmanship; manufacturer defects are handled through the OEM warranty channel.
DIY or Call Us?

There’s a safe middle ground for Mr-Glass owners. You can check the series label, photograph the failed part, and verify whether the window is under warranty - that’s useful information and costs nothing. For actual repair, we recommend stopping there. Double-hung balances are under significant tension and can release suddenly; casement operator linkages require supporting the sash weight while you work; and impact-rated units are heavy enough that two people are essential for safe handling. We’ve been called to Redwood City jobs where a homeowner cracked the IGU trying to remove a sash solo, turning a $600 balance job into a full $1,400 sash replacement. Measure twice, document once, build it so it doesn’t come back - and in this case, that means calling (650) 560-7228 before the simple fix becomes an expensive one.
FAQs
Vinyl frames typically perform 20-30 years, but the IGU seal and balance hardware often need attention at 12-18 years in our salt-air, high-UV environment. South and west exposures age fastest. Call (650) 560-7228 for an exact quote - estimates are free.
A failed IGU seal cannot be repaired - the unit must be replaced. Minor hardware like locks or operators can often be repaired with individual parts. We stock the most common Mr-Glass-compatible hardware and can confirm what’s possible on inspection. Call (650) 560-7228 for an exact quote - estimates are free.
Single-part repairs average 1-2 hours per opening. Full window replacement runs one day for 3-5 openings, two days for larger whole-house jobs, assuming standard conditions and no hidden rot in the rough opening. Call (650) 560-7228 for an exact quote - estimates are free.
We carry balances, locks, operators, and weatherstrip for the 5000, 7000, and 8000 Series on our Redwood City trucks. Specialty or discontinued parts typically arrive within 3-5 business days. Call (650) 560-7228 for an exact quote - estimates are free.
