Fast, Reliable Window Installation Across Loomis

We’re Meridian Windows & Doors, part of the Garrison Partners family, and we’ve been installing windows to The Garrison Standard since 2009. Call (817) 686-2228 for a written, line-item quote before any work starts.

Elliot Vance leads the team. He holds every job to The Garrison Standard: written price upfront, permit pulled, inspection passed, workmanship warranty for a full year.
Window Contractor in Loomis
A Window Contractor in Loomis handles the full replacement scope: removing the old sash and frame, checking the rough opening and jamb depth, setting the new unit square and level, flashing it correctly, and trimming the interior and exterior. Loomis homeowners need a window contractor when original aluminum sliders or single-pane double-hungs have lost their seal, the sashes stick, or the glass fogs between panes. Most full-frame replacements in Loomis run $900 – $1,600 per opening; insert replacements into sound frames run $650 – $1,100.
Full-Frame vs. Insert Replacement
A full-frame replacement removes everything down to the studs. It’s the right call on Loomis ranch homes where the original 1970s frames have rot or the rough opening needs re-flashing for wildfire-zone compliance. An insert keeps the existing frame and drops a new unit into the old jamb. It costs less and preserves stucco returns, but it only works when the frame is still square and sound.
Stucco Returns and Jamb Depth
Loomis has a lot of stucco homes with deep stucco returns, and that changes the install. We measure jamb depth before ordering anything. Ordering units without that measurement leads to on-site shimming, added trim, and a change order the homeowner didn’t sign up for. That’s exactly the kind of surprise our written-price policy removes.
Window Installers in Loomis
Window Installers in Loomis do the field work: setting units, shimming, leveling, flashing, caulking, and trimming. The difference between a good install and a problem install usually comes down to rough-opening prep and air-sealing at the jamb. On Loomis homes with older single-glazed units, we often find the sill flashing was never done right the first time, and that’s where air and water get in.
What Our Crews Check Before Setting a Unit
Every opening gets measured in three places: top, middle, bottom. We check for square, for level, for rot at the sill, and for jamb depth against the window spec. On a 1970s single-story ranch off Horseshoe Bar Road, we found every original aluminum slider and double-hung leaking air at the sash and jamb. We measured the rough openings, set new PGT double-hung units with low-E insulated glass to meet Placer County’s Title 24 prescriptive package, and kept the existing stucco returns intact. We pulled the county building permit, passed rough-in and final inspection, and dropped the homeowner’s summer cooling load across seven openings.
Flashing and Water Management
Water gets in at the head, the jambs, and the sill. We flash all three. On WUI lots in Loomis, the flashing detail also has to satisfy ignition-resistant assembly rules, which means the right metal, the right sealant, and no gaps at the rough opening. This is not optional paperwork. It’s the difference between a window that lasts twenty years and one that rots the wall in five.

Trusted Brands We Service in Loomis
We’re authorized to install and replace products from PGT, CGI, CWS, and ES Windows, and we stock common replacement parts for Loomis customers so turnaround stays tight. PGT double-hungs and sliders cover most of what we install in Loomis ranch homes because the frame tolerances and glass packages line up well with Placer County’s Title 24 climate zone. CGI aand CWS give us stronger frame options for lots with stricter wildfire-zone requirements. We also work with ES Windows on higher-end custom jobs. The brand gets spec’d to the house and the code, not to whatever happens to be sitting in inventory.
Common Window Installation Problems We See in Loomis Homes
- Single-pane aluminum frames from the 1970s and 1980s. These units were installed when energy was cheap and Title 24 didn’t exist in its current form. The frames conduct heat, the seals fail, and the glass fogs. Replacement is the only real fix.
- Skipped permits on replacement windows. Some contractors in Loomis will tell you a window swap doesn’t need a Placer County permit. It does, especially when the jamb or header gets modified. An unpermitted window job stalls resale and can trigger rework down the line.
- Wrong glass spec for the climate zone. Loomis sits in Placer County’s western foothills, and the building department enforces California’s Title 24 energy code, not Florida’s HVHZ or Miami-Dade NOA standards. A quote that doesn’t account for U-factor and SHGC values is a quote that fails the energy-compliance paperwork at final inspection.
- Jamb-depth mismatches on stucco and lap-siding homes. Loomis housing stock is a mix of stucco, lap siding, and older single-glazed ranch walls. Ordering units before verifying jamb depth leads to shimming, added trim, and change orders. We measure first. Then we order.

FAQs About Window Installation in Loomis
It starts with a site visit to measure every rough opening, check jamb depth, and document the existing framing condition. We write a line-item quote. You approve it. We pull the Placer County permit, order the units, and schedule the install. The crew removes the old window, preps the opening, sets and flashes the new unit, insulates the jamb, trims the interior and exterior, and cleans up. The county inspector signs off. You get a written 365-Day Done Right Promise. Call (817) 686-2228 to start.
Yes. Placer County requires a building permit for replacement windows, and the inspector verifies the glass spec against Title 24 energy requirements. Skipping the permit is a common shortcut that creates problems at resale and can force rework if the jamb or header needs modification. We pull the permit on every job and pass the inspection before we call it done. Call (817) 686-2228 with questions.
Loomis sits in Placer County’s western foothills, where Title 24 sets the U-factor and SHGC (solar heat gain coefficient) targets. Low-E insulated glass is the standard: a thin coating that reflects heat while letting light through, paired with argon or krypton fill between panes to cut conduction. The exact spec depends on your lot’s orientation and whether you’re in a wildfire-zone overlay. We run the numbers before we order. Call (817) 686-2228 for a spec check.
Nothing, if the rough opening was measured correctly. Our written price covers the scope we agreed to. The only thing that changes a Loomis quote after work starts is discovering rot, termite damage, or a header problem that wasn’t visible until the old frame came out. When that happens, we stop, show you the problem, and get written approval on a change order before proceeding. No surprise math at the door. Call (817) 686-2228 to get your written quote.
We install PGT, CGI, CWS, and ES Windows, plus ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux across our wider portfolio. For Loomis ranch homes and stucco builds, PGT double-hungs and sliders are the most common spec because they fit the frame tolerances and Title 24 glass requirements well. CGI and CWS handle stricter wildfire-zone lots. The right brand is the one that matches your house and your code, not the one sitting in stock. Call (817) 686-2228 to talk through your project.
