Frequently Asked Questions

We start with a measured survey of every opening, documenting dimensions, frame condition, and glass type. You receive that document before any quote is issued. From there we provide a written fixed price and scope, order the windows, and schedule a confirmed installation date with a named technician. On install day, the crew protects floors, removes the old sashes, sets the new units, insulates and flashes the perimeter, and reseals the exterior including stucco where needed. We document the finished work with photos and readings before we leave. Call (509) 265-6387 to start with a measurement.

A typical single-story home with 8 to 12 windows takes one to two days of on-site work in Los Angeles. Larger homes, multi-story properties, or jobs that require reframing or stucco repair can extend to three or four days. The biggest variable isn't the install itself, it's the lead time on the units once they're ordered, which runs four to eight weeks for most manufacturers. We give you a written schedule at the time of the quote and a confirmed date window before materials arrive. Call (509) 265-6387 and we'll give you a realistic timeline for your address.

Yes. We work regularly in Historic Preservation Overlay Zones, including neighborhoods like Hancock Park, Angelino Heights, and West Adams, where replacements must match original sightlines and muntin profiles. We coordinate with the Office of Historic Resources when a Certificate of Appropriateness is required and spec units that meet both the preservation standard and California's energy code. The paperwork becomes part of the job file you receive at the end. If your home falls under an HPOZ, mention it when you call (509) 265-6387 so we can factor review time into the schedule.

We do, and there are extra considerations for high-rise and condo work in Los Angeles. Many HOA boards require an owner-occupant notice, a certificate of insurance naming the association, and window units that match the existing building envelope. Our team handles the documentation with your HOA and coordinates access for window removal and disposal, which is a separate logistics step on upper floors. We never start a condo job until the HOA approval is in writing. Call (509) 265-6387 to have one of our local teams walk your building's requirements with you.

We remove and haul away all old windows, doors, and construction debris from your Los Angeles property. Aluminum frames and glass are separated for recycling where Los Angeles Sanitation and Environment accepts them, and everything else is disposed of through licensed haulers. It's included in the written quote, not a hidden haul-away fee. You'll see it as a line item on the scope. Call (509) 265-6387 if you want to know how disposal is handled at your specific property.

Yes. PGT impact-rated windows are an option we quote for Los Angeles homes, particularly where wind-borne debris coverage matters or where homeowners want a hurricane-rated unit even outside a mandatory zone. PGT's WinGuard line offers laminated glass that also cuts sound transmission measurably, which is a real benefit near the 405, the 10, or the flight paths over Westchester. We give you a side-by-side price comparison of PGT against other glass packages so you can see the cost difference in writing. Call (509) 265-6387 to discuss whether PGT fits your openings.

We can source CGI windows and doors for Los Angeles installations when impact-rated glazing is specified. CGI's Sentinel line is a common choice for coastal-facing homes from Pacific Palisades to Long Beach where homeowners want a certified impact product even though Los Angeles is not in a mandatory wind-borne debris zone. The units are heavier than standard dual-pane windows, so the structural frame condition matters more. We measure and document every opening. Call (509) 265-6387 for a written CGI quote with the lead times attached.

ViewLux is one of the brands we quote for larger fixed-glass and picture window applications in Los Angeles. The wider sightlines on these units are a good fit for the indoor-outdoor orientation of mid-century and contemporary homes from Sherman Oaks to Silver Lake. The trade term "sightline" refers to the visible edge of glass inside the frame, which is also where our name comes from. For a ViewLux price on your openings, call (509) 265-6387 and we'll put it in writing.

Vinyl windows are the lowest-cost option and perform acceptably in most Los Angeles climate zones, but they expand and contract more in the direct sun we get from the inland valleys to the coast-facing hills. Fiberglass is more dimensionally stable, paints well in dark colors without warping, and carries a higher material cost, typically 25 to 40 percent more than vinyl. Both can meet California energy code with the right glass package. We spec both and give you a written comparison. Call (509) 265-6387 to talk through which makes sense for your specific exposure.

In California, any contractor performing window and door installation for more than $500 in labor and materials must hold a C-17 Glazing Contractor license or a B General Building license issued by the Contractors State License Board. Our local teams operate under the appropriate license class for the scope, and the license number is documented on every written quote we issue. You can verify any license at cslb.ca.gov. Under the Haven Standard, every pro working under our name is required to hold the license and insurance their state requires. Call (509) 265-6387 with any licensing question before you sign a contract.

Yes. Every installer working under the Sightline Windows & Doors name must pass a background check before they enter your home, and we document that requirement as a condition of working on our jobs. We cannot speak to the screening practices of other companies. If you'd like to know the specific checks used for the team assigned to your Los Angeles location, call (509) 265-6387 and ask. We'll show you the documentation.

Yes, when a permit is required. The Los Angeles Department of Building and Safety requires permits when window openings change size, when structural headers are altered, or when certain historic districts are involved. Straight like-for-like replacements generally don't require a permit. We handle the permit application, schedule inspections, and provide you a closed permit or written confirmation that none was required for your specific scope. You'll see the permit status on your written scope before we start. Call (509) 265-6387 to find out whether your job needs one.

We carry general liability insurance and workers' compensation coverage, and we provide a certificate of insurance naming your property when your HOA, building manager, or lender requires it. It's standard practice on our jobs and it's available for review before you sign anything. Insurance documentation is part of the job file, not something you have to chase down later. Call (509) 265-6387 and we'll send the certificate to whoever needs it at your Los Angeles address.

Yes. We board up broken or compromised windows quickly to secure the opening, and the phone is answered 24/7 at (509) 265-6387. Boarding up is a temporary measure: plywood cut to the opening and secured until a replacement unit can be ordered and installed, which usually takes four to eight weeks for custom sizes. The board-up itself is a separate line item from the eventual replacement. If you've had a break-in or storm damage, we recommend calling as soon as the opening is discovered to prevent water intrusion and further property loss. Call (509) 265-6387.

First, clear people and pets from the area and close off the room if possible. Tempered glass breaks into small pebbles rather than shards, but annealed glass in older Los Angeles homes can leave sharp edges. Don't attempt to remove large glass fragments from the frame without gloves and eye protection. Call (509) 265-6387 and we'll walk you through a board-up and safe glass removal until a permanent replacement is ready. The board-up secures the opening and keeps weather and pests out while the new unit is on order.

In most cases, no, because replacement windows are manufactured to the exact dimensions of your opening, which takes four to eight weeks. What we can do same-day is board-up, glass removal, and an exact site measurement so the order goes in immediately. Any company promising a true same-day replacement is either installing a stock unit that won't match your frame or not being honest about what they did. We'll put the timeline in writing. Call (509) 265-6387 for an honest schedule.

Every window and door job is quoted in writing before it starts and leaves a documented record when we're done, under the Haven Standard. That includes a written workmanship warranty on the installation, separate from the manufacturer's warranty on the glass, frame, and hardware. Manufacturers typically cover the unit for 10 to 20 years depending on the brand and series, while our installation coverage is spelled out in your contract with the exact terms and duration. Call (509) 265-6387 to see the warranty language before you buy.

Yes, every job we quote in Los Angeles operates under the Haven Standard. The five clauses are: Have it in writing, a flat price, written scope, and written warranty before anyone starts. Arrive on schedule, a real window, a named tech, and a text when they're on the way. Verified crews, licensed, insured, background-checked, with the license number on the page. Evidence on every job, photos and readings of what we actually found. No surprises, no door upsell, no scope creep, no "while we're here." Since 2012, every window and door we've fitted has carried those terms. Call (509) 265-6387 and ask us to walk you through the standard clause by clause.

We handle it under the warranty terms in your written agreement, which is why the scope is documented before work starts and the finished job is documented with photos and readings when we leave. If a seal fails, a sash binds, or the install doesn't perform, you call (509) 265-6387, we review the job file, and we schedule a correction under warranty. The point of the documentation is that neither side has to argue about what was promised. It's in writing. Call (509) 265-6387 with any service issue and we'll pull your file.

Yes. Every door installation is quoted in writing with a flat price and a written warranty before the first screw goes in. The warranty covers our installation work including the frame, threshold, weatherstripping, and hardware mounting. The door slab and components are covered by the manufacturer's warranty, which we register on your behalf and document in your job file. If a door sags, rubs, or drafts after install, call (509) 265-6387 and we'll correct it under the terms you already have in writing.
