Windows & Doors in Pasadena - Free In-Home Measure, Written Price

Trusted Windows & Doors for Pasadena Homeowners

Windows & Doors in Pasadena typically runs $4,500-$15,000 for standard window replacement and $8,000-$25,000 for impact window installation, with most projects quoted in writing within 48 hours and crews available to start within two weeks of contract signing. Since 2007, Rowan Construction Group has delivered more than 4,000 projects across seven trades, every one with a written price before work started and a documented photo record when the crew left. In Pasadena’s varied housing stock, from 1920s California bungalows in Bungalow Heaven to mid-century ranch homes in Hastings Ranch and newer construction near the Rose Bowl, we’ve learned that window and door performance problems show up differently depending on the era of construction and the specific microclimate of the neighborhood.

What Our Windows & Doors Service Includes

Window Installation

Window installation is the full replacement of existing window units, including removal of the old sash or frame, preparation of the rough opening, installation of the new unit with proper flashing and insulation, and finish trim work inside and out. In Pasadena and nearby Windows & Doors - Arcadia communities, we see the most need for this in homes built before 1980 with original single-pane wood windows, particularly in the Madison Heights and Orange Heights neighborhoods where the original Craftsman and Spanish Colonial Revival stock remains largely intact. We measure every opening ourselves, verify square and plumb with a laser level, and specify the exact brand, model, and performance ratings in the written quote so there is no substitution at installation.

Door Installation

Door installation covers entry doors, interior passage doors, and specialty units such as Dutch doors or doors with sidelights, including frame preparation, hardware mortising, and weatherstripping. Pasadena’s older homes often have non-standard rough openings, particularly in the historic districts where original 2-1/4 inch thick solid wood doors were common, so we field-measure every opening rather than relying on original blueprints. Our written scope specifies the jamb material, hinge count and type, and the exact lockset bore and backset, because “standard prehung door” means different things to different suppliers.

Window Replacement

Window replacement is the removal of the entire existing window, frame and all, and installation of a new unit sized to the existing rough opening, distinct from sash replacement or insert installation which leaves the original frame in place. In Pasadena’s 1950s-1970s tract housing, particularly in areas like Chapman Woods and the lower Hastings Ranch, we regularly find aluminum frame windows with failed thermal breaks and corroded weep systems that have allowed water into the wall cavity. We open the interior trim to inspect the rough opening for rot or insect damage before quoting, document what we find with photos, and include any necessary framing repair in the written scope rather than discovering it mid-project.

Impact Windows & Doors

Impact windows and doors are laminated glass units tested to withstand wind-borne debris and cyclic pressure loading, required in Pasadena for new construction and substantial remodels under the 2022 California Building Code wind provisions. While Pasadena is not a hurricane zone, the Santa Ana wind events that peak in December through February can produce sustained gusts over 60 mph, and impact-rated units provide structural redundancy against tree strikes and flying debris. We specify the design pressure rating, missile impact level, and the Florida Product Approval or AAMA certification number in our quotes so the building inspector and your insurance underwriter have the documentation they need.

Energy-Efficient Windows

Energy-efficient windows are units with low-emissivity (low-E) coatings, warm-edge spacers, and argon or krypton gas fill between panes, rated by the National Fenestration Rating Council for U-factor and Solar Heat Gain Coefficient. In Pasadena’s climate zone, where cooling loads dominate and summer afternoon temperatures in the San Rafael Hills can exceed 95°F while the coastal plain stays 10 degrees cooler, we specify different glazing packages for different elevations and exposures. Our written quotes include the NFRC label data for the exact unit proposed, not generic “energy efficient” language, so you can verify the performance against the Rowan Construction Group specification and compare it to competing quotes line by line.

Sliding & Patio Doors

Sliding and patio doors are large glazed door units, typically 6 to 12 feet wide, with either inline sliding panels or folding (accordion) configurations, used to connect interior living space to outdoor areas. In Pasadena’s hillside neighborhoods like Linda Vista and San Rafael, and for Windows & Doors in El Monte properties with similar grading challenges, we pay particular attention to the sill height and drainage path to prevent water intrusion during the winter rain events that can drop 2-3 inches in 24 hours. Our written scope specifies the track system, roller capacity, and the weatherstripping configuration, and we include a water spray test at completion to verify performance.

Brands We Service for Windows & Doors

We maintain active supplier relationships and installation training across fifty-plus vetted brands, which gives us sourcing depth and honest pricing rather than inflated single-source quotes. For windows and doors specifically, we regularly specify and install Sterling vinyl and composite window lines, having completed hundreds of Sterling installations in Pasadena and our Windows & Doors in Alhambra service area; we stock common Sterling hardware and maintain direct technical support with their regional distributor, so warranty claims and parts availability do not delay completion. We also work extensively with Grohe hardware for door applications where the specification calls for premium European engineering, particularly in custom entry door sets and multi-point locking systems where the hardware cost can exceed the door slab itself.

On the roofing side of our business, which often intersects with window and door projects in full exterior renovations, we specify GAF and CertainTeed systems and understand the integration details where roof flashing meets window head casings and door sill pans. Whether you have Sterling, Grohe, GAF, CertainTeed, or any other make, we can source, install, and warranty the work. Our written quotes name the exact manufacturer and model number, not a product category, so you know what you’re buying before you sign.

Signs You Need Windows & Doors Right Now

• Draftiness or temperature stratification near windows. If you feel a distinct temperature drop within three feet of a closed window in January, or if your HVAC thermostat is in a different room from the window wall and the system cycles excessively, the weatherstripping has likely hardened or the sash no longer seats squarely in the frame. In Pasadena’s older homes with weight-and-pulley double-hung windows, we’ve found that decades of paint buildup and rope deterioration allow the sash to rack in the jamb, creating gaps that caulk cannot fix.
• Visible moisture between glass panes. Fogging or droplets inside a sealed insulating glass unit means the edge seal has failed and the desiccant is saturated, permanently reducing the unit’s thermal performance; the glass cannot be “re-sealed” in the field and requires full unit replacement. We see this most often in south- and west-facing windows in Pasadena, where daily thermal cycling stresses the edge seal, and in units installed before 2010 when warm-edge spacer technology was less common.
• Difficulty operating sashes or doors. Windows that require force to open or won’t stay open, or doors that drag on the threshold or have loose latches, indicate frame racking, hardware wear, or substrate movement beneath the sill. In the foothill areas of Pasadena, where expansive clay soils are common, we’ve diagnosed dozens of cases where door operation problems traced to foundation movement rather than the door itself, and we include a level check of the rough opening in our inspection protocol.
• Rot or insect damage in window frames or door jambs. Soft wood that accepts a screwdriver blade easily, or sawdust-like frass beneath exterior trim, indicates active decay or infestation that will spread to adjacent framing members if not addressed. Pasadena’s Mediterranean climate, with wet winters and dry summers, creates ideal conditions for drywood termite colonization, and we regularly find concealed damage behind intact exterior paint that only becomes visible when we remove the interior casing during the inspection.
• Exterior noise intrusion. If traffic noise from the 210 Freeway corridor, aircraft from Burbank or LAX flight paths, or neighborhood activity is audible with windows closed, the glazing mass and airspace are insufficient for the acoustic environment. Standard dual-pane windows provide roughly 28-32 STC (Sound Transmission Class); upgrading to laminated glass or increasing the airspace to 1 inch or more can improve this to 35-40 STC, a perceptible reduction that we can demonstrate with manufacturer test data in the written quote.

Our Windows & Doors Process - Step by Step

1. 1
   On-site measurement and condition assessment. We visit your Pasadena home with a laser measure, moisture meter, and inspection camera, and we remove interior trim selectively to inspect the rough opening condition. We photograph everything, document the existing unit manufacturer and any visible defects, and note structural or environmental factors, such as the southwest exposure that accelerates seal degradation on Colorado Boulevard-facing elevations.
2. 2
   Written quote with line-item scope and specifications. Within 48 hours of the site visit, we deliver a flat-price quote that names the manufacturer, model, performance ratings, and installation details for each unit. Under Clause 1 of The Haven Standard, this written price is delivered before any work starts, every time, and includes a 365-Day Done Right Promise printed on the page.
3. 3
   Material procurement and permit application. Upon acceptance, we order materials with confirmed lead times and apply for any required permits with the City of Pasadena Building & Safety Division. For impact-rated units or projects in the historic districts, we prepare the additional documentation for design review or structural calculations, and we include permit fees and inspection scheduling in the project timeline we provide you.
4. 4
   Installation by background-checked, uniformed crews. Our installers arrive with the documented photo record from the assessment visit, install per manufacturer specifications with proper flashing integration and insulation, and perform a water spray test on exterior units to verify drainage path performance. No work proceeds on a change until the change order is signed, the discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs.
5. 5
   Final inspection, documentation, and warranty registration. We walk the completed installation with you, review the photo record of before, during, and after conditions, and provide the written warranty documentation with manufacturer registration completed. The 365-Day Done Right Promise is in effect from this date; if it is not done right, we make it right.
