Window & door installation you can trust.

Most window replacements take 30 to 60 minutes per opening once the crew is on site. A typical whole-house project of 10–15 windows usually finishes in 1–2 days. We give you a precise schedule after the on-site assessment so you can plan around it.

Cost depends on the size of the opening, the type of window (casement, double-hung, sliding, etc.), the frame material, and the glazing package. Every project is quoted individually after we measure on site and review your goals. We are upfront about pricing and never use high-pressure sales tactics.

Common signs include drafts you can feel near closed windows, condensation between glass panes, frames that are warped, rotted, or hard to operate, and noticeable outside noise indoors. If your windows are 20+ years old and single-pane, you'll likely see real energy savings and comfort gains from a modern dual-pane replacement.

Yes — we work with a wide range of window styles, frame materials (vinyl, fiberglass, clad-wood, aluminum), and glass packages (dual-pane, triple-pane, Low-E, tempered, laminated). During the consultation we'll recommend the right combination for your home, climate, and budget.

Yes. We install entry doors (steel, fiberglass, wood), sliding patio doors, French doors, and interior doors. Door installation goes hand-in-hand with window work — same crew, same quality standards, often the same project.

Yes. We offer free, no-obligation on-site estimates. The visit takes about 30 minutes — we measure, ask about your goals, walk through the options, and follow up with a written quote. No pressure to commit.

Yes. We are fully licensed (California CSLB) and carry both general liability and workers' compensation insurance. We're happy to provide our license number and certificates of insurance on request.

Many ENERGY STAR–certified windows qualify for the federal 25C energy-efficiency credit, and depending on where you live there may be utility or local rebates on top. What you can claim depends on your city, your home and the products installed, so we go through the numbers that actually apply to you during the free estimate — and your city page lists the programmes we see locally.

Title 24 is California's building energy efficiency standard. Window replacements typically must meet specific U-factor and Solar Heat Gain Coefficient (SHGC) thresholds depending on your climate zone. We only install Title 24–compliant products and handle the documentation your building department needs.

A retrofit (replacing in the same opening, same size) typically does not require a permit in most Bay Area and Marin jurisdictions. A new opening, an enlargement, or any change involving structural framing usually does. We confirm permit requirements with your city before starting work and handle the application if needed.

A typical dual-pane Low-E replacement uses about 25–30% less energy for heating and cooling than the original single-pane window. Triple-pane and specialty coatings push that further. Real savings depend on your local climate, sun exposure, and how leaky the original windows were — we'll set realistic expectations during the estimate.

Our installation comes with a workmanship warranty covering the labor and seal of every window we install. The windows themselves carry the manufacturer's product warranty, which varies by brand — most are limited lifetime warranties on the glass and frame. We'll go through warranty specifics during your estimate.

Yes — we specialize in retrofitting modern thermal performance into historic homes while preserving original profiles, divided lights, and trim detail. We work with shops that produce period-correct sashes and casements when standard products don't fit the architectural language.

We keep disruption minimal. Each opening is removed and replaced the same day — we don't leave your home open overnight. We use drop cloths, vacuum after each window, and the crew cleans up so the only sign of the project is your new windows.

Yes — when needed. Most retrofit installations require minimal exterior patching, which our crew handles in-house. For larger openings or new windows that require enlarging the rough opening, we coordinate with stucco or siding specialists as part of the same project.
