Fast, Reliable Window Installation Across Lennox
Window installation in Lennox almost always comes down to one thing: getting the measure right on an older stucco home before the first unit is ordered. Most houses here were built between the 1930s and 1960s, which means shallow jambs, nonstandard openings, and exterior walls that need careful patching after the old sash comes out. That’s the work we do every week. If you’re in Lennox and want a written price before anything gets touched, call (817) 686-2228.

We’re Meridian Windows & Doors, part of the Garrison Partners network and held to The Garrison Standard on every job. Elliot Vance leads our crews. We work across Lennox, from the blocks off Hawthorne Boulevard down to the streets near Lennox Park, and we know what these homes throw at you once the trim comes off.
Why Meridian Windows & Doors Is Lennox’s Preferred Window Installation Company
We show up when we say we will. That’s the whole pitch, and for Lennox homeowners who’ve dealt with no-show contractors, it matters more than any brochure claim. Our technicians are background-checked and uniformed, so when the van pulls up on Inglewood Avenue or a side street off Lennox Boulevard, you know exactly who’s walking to your door.
The price goes on paper before work starts, and it does not move at the door. No “we found something” phone calls once the stucco is open. If we spec six units, you pay for six units at the number we agreed on. Every install is covered by our 365-Day Done Right Promise in writing. If the work fails within a year, we come back at no charge. No fine print about labor exclusions.
We also answer the phone. A live person picks up 24/7, every day of the year. Not a voicemail loop, not a call center script. When a Lennox homeowner has a question about their estimate or wants to schedule a site measure, they get a human being.
Bay Window Installation in Lennox
Bay window installation in Lennox is one of the more involved retrofit jobs on these older stucco homes, and it’s where we see the most difference between a clean install and a rushed one. A bay window projects outward from the wall, which means roof support, cantilever framing, and a proper seat board need to be evaluated before the unit is ordered. On the single-story bungalows typical of this area, the existing bay was often site-built decades ago, not a manufactured unit. That changes the scope.
What the Job Involves
The old bay comes out in sections, then we inspect the rough opening, the support knees, and the condition of the stucco return below the unit. New construction in Lennox almost never gets a bay retrofitted from scratch instead, it’s a replacement of an existing projection. We measure the seat depth, the angle of the side units, and the projection distance to the inch. The wrong projection leaves the roof line unsupported. The right one keeps the interior trim tight and the exterior flashing sealed.
What a Lennox Homeowner Should Expect to Pay
A bay window replacement in Lennox typically runs $3,200 to $6,800 installed, depending on the number of lites, the glass package, and whether the roof and seat board need reinforcement. A full removal and rebuild of a site-framed bay can push closer to $9,000. If you’re pricing this, make sure the quote specifies whether the support knees and exterior roof flashing are included. Ours always does, in writing, before the first screw turns.
Window Contractor in Lennox
A window contractor in Lennox has to understand something most national installers don’t: this is an unincorporated LAX-adjacent community with dense, older housing stock, and nearly every job is a like-for-like retrofit rather than a new rough opening. That changes everything about how the work is scoped. You’re not cutting new holes in framing. You’re pulling sash out of an existing jamb, dealing with whatever’s behind it, and putting a new unit into a space that may have shifted over 60 years.
Site Measuring Before the Order
We measure every opening before a single unit is ordered. On many Lennox bungalows, previous retrofits left nonstandard widths and depths. The window that was installed in 1987 might not be the size the original frame was built for. Ordering off old measurements is the most common way a $600 job turns into a $1,900 rebuild. We don’t do that.

Stucco Returns and Jamb Depth
After the old sash comes out, we check the jamb depth. On a 1940s stucco bungalow just off Hawthorne Boulevard, our crew replaced six original wood double-hungs with CGI vinyl retrofit units glazed with low-E insulated glass and a laminated interlayer. The old jamb measured about 3 inches after we pulled the sash. Instead of opening up the stucco, we used extension jambs and patched the exterior return with matching material. Every opening came in on the same line item we scoped, and we left the homeowner a manufacturer spec sheet for their insurer.
Trusted Brands We Service in Lennox
We’re authorized to install and replace products from PGT, CGI, and ViewLux, among the eight manufacturer lines we carry. For Lennox homeowners, brand choice usually comes down to two things: glass package for the sun load, and frame profile to match the existing trim. PGT and CGI both offer laminated glass options that make sense in a dense neighborhood where noise from Hawthorne Boulevard or LAX flight paths is a real factor. We stock common local parts and hardware so service calls don’t stall waiting on a shipment. Call (817) 686-2228 and we’ll walk you through which line fits your home.
Common Window Installation Problems We See in Lennox Homes
- Nonstandard openings from prior retrofits. Many Lennox bungalows have been retrofitted once or twice already. The opening you’re looking at may not match the original framing dimensions, so the unit that gets ordered doesn’t drop in cleanly. We measure every opening before ordering, and we flag any jamb that will need rebuilding.
- Failed stucco-to-jamb seals. In this dense, unincorporated neighborhood the exterior wall is often stucco over old framing. If the flashing and sealant detail is rushed, water intrusion shows up in the interior plaster within a season. We spend extra time on the exterior return and install the sealant to manufacturer spec, not to what’s fastest.
- Wrong design pressure or labeling on the unit. Lennox homes fall under specific building code requirements. If the wrong rating or label arrives, the inspector flags it and the whole opening has to be re-ordered. That turns a one-day set into a multi-week delay. We confirm the rating before the order goes in.
- Shallow jambs that complicate the retrofit. Original wood double-hungs in 1940s Lennox homes often sit in jamb depths under 3.5 inches. Modern vinyl units need more room. We address this with extension jambs rather than tearing open stucco walls, which keeps the exterior intact and the cost predictable.

FAQs About Window Installation in Lennox
It starts with a site measure of every opening we’re replacing, followed by a written line-item quote. Once you approve, we order the units, schedule the install, pull the old sash, address the jamb, set the new unit, seal the exterior, and patch any stucco return. A typical single-window retrofit takes one day; a full-home set of six to eight openings takes two to three days. Call (817) 686-2228 to schedule your measure.
Yes, in most cases. Lennox is an unincorporated Los Angeles County community, and like-for-like window replacements still require a building permit and a final inspection. We pull the permit, schedule the inspection, and make sure the units carry the correct design pressure labeling before they’re installed. If the inspector flags something, we’re the ones who fix it, not you.
Once we’ve measured and you’ve approved the quote, standard vinyl retrofit units are typically installed within two to four weeks. Custom sizes or specialty glass packages can run longer. We don’t promise same-week turnaround on planned work; we promise a date we’ll actually hit. Call (817) 686-2228 to get on the schedule.
Yes, and for Lennox specifically, low-E glass makes a measurable difference. The community sits inland from the coast and catches direct afternoon sun most of the year. Low-E glass (a thin coating that reflects heat while letting light through) reduces solar heat gain, which cuts how hard your AC runs in August. Paired with insulated frames, you’ll notice it in the August bill.
Three things: a nonstandard rough opening that requires jamb rebuilding, a stucco return that’s deteriorated and needs more extensive patching than expected, or a unit that was mis-ordered and has to be re-specified. We minimize all three by measuring before ordering and checking the jambs at the estimate stage. If we do find something mid-job, we tell you before we do anything and the change is in writing. That’s the Garrison Code. Call (817) 686-2228 for an exact quote on your home.
