Our crews work retail street fronts, condominium associations, rental buildings and office suites, phasing every opening around tenants, residents and business hours so suites stay leased and doors stay open. Backed by 13 years in business and our 2-year workmanship warranty on every installation, we have completed over 1,730 projects, and property manager and contractor references are available on request.
From the elevation-by-elevation takeoff and product submittals to the punch list and the closeout binder, our team handles the parts of a commercial window job that decide whether it finishes on schedule. Serving Carlsbad, Bonsall, Poway and the beach cities of Encinitas and Solana Beach, we hold the general contractor's schedule, work nights and weekends where a building cannot close, and turn each phase over ready for inspection.
Why Carlsbad Quality Windows
We take on commercial window work from a single shop front of 6 storefront panes, street-facing retail, up to association and rental programs of 48 to 64 windows. Between those sits the office suite, such as the 10 fixed office windows, tenant improvement in Poway Business Park, and mixed sites like a working ranch in Bonsall on rural larger lots. That ranch job put 14 windows, ranch office and barn apartments, on one spec of vinyl sliders, dual-pane Low-E, for an estimated $12,600 to $16,800 over an estimated 2 to 3 days in a single mobilization.
Most of our commercial calendar falls into four building types, and each one has its own page with the detail a buyer needs.

Commercial windows around Carlsbad are typically budgeted per opening, with a retrofit vinyl double-hung estimated at $450 to $950 per window and a storefront glass pane estimated at $900 to $3,000 per pane, and the frame system, access and the number of phases move the figure most.

Ellen's bluff-top condominium association in Solana Beach replaced every original slider on the ocean elevation at once, 48 windows across 12 units, one association, in white vinyl sliders, dual-pane Low-E. The board approved one color and grid spec, we phased two units a day with notices to residents, and the estimated $41,000 to $58,000 program ran an estimated 7 to 11 days with no resident out of their home overnight.
Gary's lakeside apartment building at Lake San Marcos had original aluminum windows in every unit, so we set white vinyl single-hung, dual-pane Low-E, in all 64 windows across 16 apartments. Four units a day were released with resident notices, the work came in at an estimated $24,500 to $33,000 over an estimated 7 to 10 days, and one unit-by-unit punch list closed it out.
A commercial window bid with us runs in seven steps, and each one produces a document your general contractor or board can file.

On a commercial window job the biggest scope driver is phasing an occupied building, since every opening we remove belongs to a room a tenant pays for. We size each block of work to fit one shift, so plywood never spends a night where a window used to be. Office floors and medical suites can move to evenings or weekends, shops get their glass before the doors open, and hallways are covered, walked off and posted with notices before any frame comes out.
Commercial glass in Carlsbad is checked against California's Title 24 energy rules and the safety glazing sections of the California Building Code, and every unit we install carries the labels an inspector reads. Doors, sidelights near doors and large low lites in lobbies get tempered or laminated glass with the maker's permanent mark in the corner. The NFRC label stays on each new window until final, and the closeout binder records the U-factor and SHGC for the building file.

Most commercial orders typically take an estimated 4 to 12 weeks from final measure to install day, and custom finishes or storefront framing sit at the longer end. Once units arrive, a crew of 2 to 4 installers works each phase, and a 2-person crew sets 8 to 12 retrofit windows a day, so a 64-window building is usually planned as an estimated 7 to 10 days of phased work.
Property managers choose us because the crew that bids the building is the crew that installs it, and after 13 years and 1,730 projects we know what a commercial schedule can absorb. Our commercial project coordinator writes the resident and tenant notices with you, keeps a unit-by-unit punch list and sends progress by building. Every opening carries our 2-year workmanship warranty on every installation, plus manufacturer warranties passed through to you, commonly 20 years on the glass and 10 years on non-glass parts.

We bid commercial window work within a 30-mile radius of Carlsbad, from shop fronts in Carlsbad Village and Leucadia to offices in Poway Business Park and rentals beside the lake at Lake San Marcos. Associations in Solana Beach, Del Mar and Encinitas and ranch properties in Bonsall are bid the same way, and our residential side is on the Carlsbad Quality Windows home page.
Each building type has its own page: storefront glass and aluminum entrances for shops and restaurants, HOA and condo window projects for boards that need one approved look, apartment window replacement with tenants in place for rental owners, and office and tenant improvement glazing for build-outs.

Our smallest commercial jobs are usually a single shop front of about 6 storefront panes, and there is no upper limit we have hit on association or apartment work.

Yes, product data, NFRC ratings and shop drawings go in for approval, and a closeout binder with warranties follows the punch list.
Yes, our own installers set every unit, from a Bonsall ranch office to full apartment programs, so one crew lead answers for the work.

Contact us with the property type, opening count, drawings if you have them and your target dates, and we will walk the building and return a written bid.



The process
We check every frame, sill and the stucco around it, then laser-measure each opening for the unit that goes in it.
Frame material, glass package, label values and install method arrive in writing before anything is ordered.
Each window is set on a sloped sill pan, flashed and sealed, with the NFRC sticker left on for the inspector.
We open and lock every window and door with you, and the city signs off the Title 24 permit.
