Yes. Quote review is free at SideGuy. We don't take referral fees from window companies and we don't sell installation services. Our only interest is giving you honest guidance before you sign a contract worth thousands of dollars.
Insert (retrofit) replacement keeps the existing frame in place and fits a new window unit inside it — faster and cheaper, but only works if the existing frame is in good condition. Full-frame replacement removes the entire window assembly down to the rough opening — better for energy performance and water-proofing but more expensive and invasive. Most San Diego sales pitches default to full-frame because the margins are higher; for many homes, insert replacement is adequate.
San Diego Building Inspections requires permits for window replacements that change the size or configuration of the opening, or involve structural work. Many standard "same-for-same" insert replacements can be done under a permit exemption, but always confirm with your contractor in writing. Work done without required permits can complicate home sales and insurance claims.
Milgard (made in California, strong local dealer network), Andersen, Simonton, and Pella are all well-regarded. Avoid brands you can't look up independently — some window companies sell rebadged import windows under proprietary brand names with no manufacturer backing. Always ask for the actual manufacturer name separate from the installer's brand.
That's a red flag. A legitimate window installer has no reason to object to a homeowner taking 24 hours to have a bid reviewed. High-pressure resistance to independent scrutiny — especially on a $10,000+ project — is itself a reason to look elsewhere.

Permits required for structural rough opening changes and any new openings. Like-for-like replacements in the same frame opening typically do not require a permit in San Diego. Budget $300–$1,500 for permit fees on mid-range projects. Permit fees are a legitimate hard cost — any quote that omits them is understating the true project cost.
$75–$150/hr. Installation of a standard window runs 1–2 hours per window.. On a typical project, labor accounts for 30–50% of total quoted cost. The specific crew skill level, travel distance, and San Diego's high cost of living all push labor rates above national averages.
Vinyl dual-pane: $150–$600/window. Fiberglass: $500–$1,200/window. Aluminum: $200–$800/window. Low-E coating and argon fill are standard in San Diego's climate zone. Material prices in San Diego track 8–15% above national averages due to supply chain routing and local fuel costs. Ask for a materials breakdown — understanding what you're paying for reduces negotiating friction.
Window contractors typically mark up product 30–60% above wholesale. Ask for the product model number so you can verify retail pricing independently. Margin itself is not a problem — contractors need it to sustain a licensed, insured business. The problem is when margin is hidden inside inflated line items rather than stated transparently.
Every contractor doing work in California must hold a current, active license from the Contractors State License Board (CSLB). For window replacement work, the relevant classification is C-17 (Glazing Contractor) for window installation.
The CSLB lookup takes 60 seconds and shows: current license status, bond amount, workers' compensation status, and any enforcement history. A contractor who discourages you from verifying their license is a contractor worth reconsidering.
What to verify: license number matches the contractor entity on your contract, license status is "Active," bond is current, and workers' comp is in force (or contractor has a valid exemption).
The lowest bid on a window replacement project in San Diego is not always — and not usually — the best value. Low bids typically mean one of three things: scope has been omitted, permits are being skipped, or the materials specification is lower-grade than the competing bids.
A complete, honest bid that is 15% higher than the lowest quote is almost always the better financial decision. The cost of a failed inspection, a scope dispute, or unpermitted work discovered during a future home sale typically exceeds the initial bid difference by 3–5x.
The right question is not "who is cheapest?" but "whose quote is most complete?" A bid that accounts for permits, proper disposal, licensed subcontractors, and a written warranty is protecting your investment — not inflating it.
