Boral Windows & Doors: The San Francisco Owner’s Guide
If you have a Boral window or door with a failed sash, a shot roller assembly, or a stripped operator, here’s the straight answer: replacement parts and full unit swaps in San Francisco typically run $295 to $2,125 for hardware-level repairs, and $5,310 to $17,700 for full replacement windows or doors, installed, depending on size and series. We stock common Boral-compatible hardware and can usually schedule a diagnostic visit within a few days. Most San Francisco homeowners discover the problem the same way: a window that won’t stay open, a patio door that grinds on its track, or a lock that no longer engages cleanly. One morning it works, the next it doesn’t. By then, the failed part has usually been wearing for months.
Which Boral Models This Applies To
Boral’s window and door lines in the U.S. market have shifted over the years, and that matters when you’re trying to match a part. The two most common series we see in San Francisco homes are the Boral 650 Series single-hung and the Boral 850 Series casement and awning windows, plus the matching Boral patio door lines. If you still have the original paperwork, the series number is printed on the order confirmation. If you don’t, remove the sash and look for a small white or silver sticker on the frame’s inner channel; that label usually carries the manufacturing date and series code. Here’s the compatibility gotcha most owners run into: Boral changed the balance shoe design between the 2008-2014 production runs and the 2015-and-later units. A balance shoe from a 2010 unit will not seat properly in a 2016 frame, even if the window looks identical. Measure the shoe’s width with a tape measure before ordering anything, and if you’re within a millimeter, it matters.
For most Boral hardware, OEM parts are the right call when the unit is under a transferable manufacturer’s warranty or when the failure is in a load-bearing component like a sash lock or hinge. For consumables like weatherstripping, glazing bead, and nylon roller assemblies, quality aftermarket equivalents often match OEM performance at a lower price. We stock both paths and will give you a written price on each before any work starts.
One more thing worth knowing: we are an independent San Francisco contractor, not a Boral dealer or factory affiliate. That independence means we can recommend the aftermarket option when it’s the smarter spend, because we’re not tied to pushing factory-only parts.
Styles & brands we work with
Signs Your Boral Windows & Doors Are Failing
- Casement window won’t stay open. The crank operator’s gear teeth have stripped, or the arm rivets have wallowed out. This is the single most common Boral failure we see in damp, coastal San Francisco neighborhoods like the Outer Sunset and Richmond District, where salt air accelerates wear on zinc-plated operator arms.
- Patio door grinds or catches mid-track. The nylon roller assemblies have flat-spotted or the roller housings have corroded. Boral patio doors use a two-wheel tandem roller with a specific 1-1/4 inch diameter; generic big-box rollers will ride too high and bind.
- French door won’t seal or lock. The multipoint lock’s center gear has slipped out of timing, usually because the door has settled against a floor that shifts with San Francisco’s clay-heavy hillside soils. Adjusting the hinges helps temporarily; re-timing the lock helps for years.
- Single-hung window slams when closing. That’s a failed block-and-tackle balance or a broken spiral balance. It’s also a genuine safety issue: that sash can weigh 40 pounds or more, and when it drops, it drops hard. Keep your fingers clear and call a crew that knows how to set the tension correctly.
- You can see daylight around the glass, not the frame. The glazing bead or the sealant at the insulating glass unit perimeter has failed. In San Francisco’s fog belt, a failed IGU seal shows up fast: condensation between the panes is the tell, and it won’t go away on its own.

AfterReplacement Cost & What’s Included
For Boral windows and patio doors in San Francisco, here are the installed price ranges we work within, and they hold steady across most neighborhoods:
- Hardware-level repair (operator, lock, roller, balance): $295 – $825
- Sash rebuild or IGU replacement (single unit): $470 – $1,180
- Full window replacement (per opening, Boral-compatible): $710 – $2,950
- Full patio door replacement (standard slider or French): $2,360 – $5,310
What drives the range is the series, the size of the opening, and the condition of the surrounding frame. A straight hardware swap on a 2016 Boral 850 casement is a two-hour job. A full-door swap where the original flashing was installed wrong and the sub-sill needs repair is a different day. Every price we quote is written, line-itemed, and fixed before work starts. No numbers that move at the door. And what we install carries the 365-Day Done Right Promise: if the repair fails within a full year, we come back and correct it at no charge.
DIY or Call Us?
There are a few things you can safely check yourself. If a window is binding, remove the sash and look for loose screws or obvious debris in the track. If a door is grinding, clean the bottom track and check whether the rollers look cracked or flat-spotted. You can usually identify the problem with a flashlight and ten minutes. The repair itself is where it goes wrong, because Boral hardware is specific. The balance shoe, the roller diameter, the operator arm geometry: these are not generic. A wrong part will bind, bind, and then snap. And if you’re looking at a single-hung that won’t stay up, that’s a high-tension balance. Compressed springs and heavy sashes are not worth a hand injury. Call us at (831) 610-5598. We’ll put a real number in writing so you can decide with the facts.
FAQs
Expect 15 to 25 years of serviceable life from Boral window frames and door slabs in San Francisco, with hardware like operators and rollers typically failing at the 10-to-15-year mark first. Coastal fog zones shorten hardware life; interior-conditioned units last the longest. Call (831) 610-5598 if you want an honest assessment of what’s left in your units.
Yes, about 70% of the Boral issues we see can be repaired at the hardware level: a new balance, a re-timed latch, a replacement operator, or fresh rollers. Full replacement only makes sense when the frame is compromised or the glass unit seal has failed on multiple panes. Call us for a free estimate and we’ll tell you straight which path your unit needs.
A single hardware swap, like a casement operator or a pair of rollers, takes one to two hours including testing. A sash rebuild or an IGU swap runs half a day. A full patio door replacement is usually a one-day job, and we pull the permits when the opening is structural. We’ll give you the timeline in writing before we start.
Our San Francisco service truck carries the most common Boral-compatible hardware: 650 and 850 series balance shoes, casement operators, multilock gear sets, and 1-1/4 inch patio door rollers. If we don’t have your exact part on hand, we can usually source it inside of a week. We also work with OEM and aftermarket suppliers, and we’ll quote both options. We also stock parts from KraftMaid, Cambria, and Silestone product lines for the cabinetry and surfacing work we do. Call (831) 610-5598 and we’ll check the truck while you’re on the phone.
