Pomona’s inland valley climate puts unique stress on fenestration. Summer highs regularly top 90 degrees, winter lows dip to the 40s, and the Santa Ana winds push sustained gusts past 40 mph through neighborhoods like Phillips Ranch and Lincoln Park. We’ve measured frame gaps that let conditioned air escape at rates costing homeowners $200-plus annually in wasted utility spend, and we’ve replaced impact-rated units in north Pomona foothill homes where flying debris during wind events cracked standard glass. Our crews are background-checked, uniformed, and carry a live photo documentation system on every visit. Under Clause 1 of the Haven Standard, the written price is delivered before anyone starts. That’s been our practice since Grant Rowan founded the company in 2007.

What Our Windows & Doors Service Includes

Window Installation

New window installation in Pomona covers everything from rough-opening preparation to final trim and seal. We install vinyl, fiberglass, aluminum, and wood-clad units across single-hung, double-hung, casement, and fixed configurations. Our crews verify square and plumb to within 1/8 inch, install proper sill pan flashing (the sloped membrane that directs water out, not in), and foam-seal the gap between frame and rough opening to stop air infiltration at the source. Every install includes a written warranty and the standard documented photo record.

Door Installation

Door installation spans entry doors, interior passage doors, and specialty units like Dutch doors and barn-door hardware systems. We measure the rough opening, check the subfloor for level, and shim the jamb to maintain consistent reveal (the even gap between door edge and frame) before securing with long screws into the framing, not just the trim. For Pomona’s older housing stock, particularly in the Mayfair and Westmont neighborhoods built in the 1940s-1960s, we often find out-of-square openings requiring custom jamb work rather than big-box prehungs.

Window Replacement

Window replacement removes the existing sash and frame, or in full-frame replacement, the entire unit down to the rough opening. A typical Pomona home with 10-15 windows runs $4,500-$15,000 for vinyl replacement, with fiberglass and composite frames at the higher end. We check for rot in the sill and surrounding sheathing during removal, a step that catches hidden water damage before the new unit goes in. Under the Haven Standard, any rot repair needed is quoted in writing before proceeding, never added as a surprise.

Impact Windows & Doors

Impact-rated windows and doors use laminated glass (two glass layers bonded to a shatter-resistant interlayer, typically polyvinyl butyral) and reinforced frames tested to ASTM E1886 and E1996 standards. In Pomona, these are often specified for foothill properties with exposure to wind-borne debris, or for homeowners seeking the security benefit of forced-entry resistance. Impact window installation in Pomona typically runs $8,000-$25,000 for a full-home package. We verify the specified design pressure rating (the structural load the unit must withstand, measured in pounds per square foot) matches your home’s exposure and local code requirements.

Energy-Efficient Windows

Energy-efficient windows reduce thermal transfer through low-emissivity (low-E) coatings, argon or krypton gas fills between panes, and warm-edge spacers that reduce condensation. For Pomona’s climate zone (CEC Climate Zone 10), we specify windows with a U-factor below 0.30 and Solar Heat Gain Coefficient (SHGC) tailored to orientation, east- and west-facing units getting lower SHGC to block afternoon heat gain. The utility savings typically run 10-25% of heating and cooling costs, with payback periods of 5-12 years depending on current window condition and energy rates.

Sliding & Patio Doors

Our Windows & Doors in Chino Hills and Pomona sliding and patio door installation replaces or adds large glazed openings for backyard access, a common request in Pomona’s ranch-style and mid-century homes. We install standard two-panel sliders, three-panel multi-slide systems, and lift-and-slide units with hardware that drops the panel onto its track seal when closed. Proper installation requires a level sill, correctly flashed head detail, and often a structural header if the opening is widened. For impact-rated patio door needs, we specify units with multi-point locking and reinforced interlayers.

Impact Garage Doors

Impact-rated garage doors use reinforced panels, heavy-duty track systems, and wind-load-rated hardware to withstand pressure cycling without failure. In Pomona’s wind-exposed areas, particularly north-facing garage doors on foothill properties, we install doors rated for the specific wind speed zone (typically 110 mph for inland Los Angeles County per ASCE 7). The installation includes upgraded track brackets, struts, and often a jackshaft opener to reduce overhead clearance needs.

Custom & Geometric Windows

Custom and geometric windows, round-tops, trapezoids, and polygon units, require precise field measurement and often factory templating. We’ve sourced custom shapes from manufacturers including Windows & Doors in Pomona specialty suppliers for historic homes in the Wilton Heights district and for contemporary new builds in the Ganesha Hills area. Lead times typically run 4-8 weeks, quoted in writing with the price.

Hurricane Impact Windows

Hurricane impact windows meet the same structural standards as general impact windows but are specifically tested for large-missile impact (a 9-pound 2×4 fired at 34 mph) and cyclic pressure loading. While Pomona is inland from hurricane zones, the testing protocol provides the highest level of wind and debris protection available, and some homeowners in exposed locations specify them for that reason. We verify Miami-Dade County or Florida Building Code approval on every unit specified.

Impact Sliding Glass Doors

Impact sliding glass doors combine large glazing areas with laminated impact-rated glass and reinforced frames. Installation requires careful handling of heavier glass lites (a 10-foot two-panel door can weigh 400-plus pounds) and precise alignment of the track system for smooth operation under load. We specify multi-point locks and often integrated blinds between the glass layers for privacy without separate window treatments.

Brands We Service for Windows & Doors

We’ve worked with Mighty Buildings panelized window systems on several accessory dwelling unit projects in Pomona and Claremont, integrating their factory-cut openings with site-installed flashed units. Their precision-cut rough openings reduce field adjustment time, and we’ve developed a protocol for sealing the panel-to-window interface that we document on every ADU install.

Boxabl units, including their Casita product line, come with pre-installed windows and doors that occasionally need replacement or upgrade after delivery. We’ve serviced Boxabl installations in the Pomona area, sourcing compatible replacement units and adapting standard flashing details to their steel-frame construction.

Plant Prefab homes use high-performance window specifications as part of their net-zero-ready packages. We’ve partnered with Plant Prefab on warranty service and owner-requested upgrades in the broader Los Angeles basin, including Pomona-area deliveries, and we stock common hardware and seal profiles for faster turnaround.

Whether you have Mighty Buildings, Boxabl, Plant Prefab, Tuff Shed, or any other make, we can help. Our fifty-plus vetted brand relationships mean we source at honest cost, not inflated retail, and the written quote reflects that.

Signs You Need Windows & Doors Right Now

• Drafts you can feel around closed windows. Air movement past weatherstripping or through frame gaps indicates seal failure. In Pomona’s climate, this forces your HVAC system to compensate year-round, and we’ve measured single-pane aluminum-frame units losing 30% more energy than modern replacements.
• Condensation between double-pane glass layers. Fogging you can’t wipe off means the insulated glass unit (IGU) seal has failed, letting moist air into the cavity. The low-E coating and gas fill are already compromised, and thermal performance drops to near single-pane levels.
• Difficulty opening, closing, or locking. Binding sashes, stuck sliders, or latches that won’t engage indicate frame distortion, balance system failure, or hardware wear. A window that won’t lock is a security vulnerability, and a slider that jumps its track is a safety hazard if emergency egress is needed.
• Visible frame rot, water stains, or soft spots. Wood and wood-clad frames in Pomona’s older homes, particularly pre-1980s construction, often show decay at the sill where water ponds. We’ve replaced full rough openings where rot extended into the surrounding sheathing, a cost that multiplies if ignored.
• Exterior noise intrusion. Single-pane windows provide minimal acoustic damping. If freeway noise from the 10 or 60 corridors, or aircraft from Brackett Field, is audible with windows closed, laminated or thicker IGU glass can reduce sound transmission by 50% or more.

Our Windows & Doors Process - Step by Step

1. 1
   On-site measurement and condition assessment. We arrive with laser measuring tools, moisture meters, and a photo documentation system. Every opening is measured in three places (width at top, middle, bottom; height at left, center, right) to catch out-of-square conditions. We photograph existing conditions and any damage for the record you receive.
2. 2
   Written quote with line-item scope. Under Clause 1 of the Haven Standard, you receive a flat written price before any work starts. The quote specifies manufacturer, model, glass package, hardware finish, and installation details. No “call for pricing,” no range that shifts later.
3. 3
   Order and scheduling. Once you approve, we place the order and confirm lead times, typically 2-6 weeks for standard sizes, 4-10 weeks for custom or impact-rated units. We schedule installation when materials are in hand, not before, so your crew doesn’t arrive to an empty truck.
4. 4
   Installation with documented progress. Crews remove existing units, repair rough openings as needed, install new windows or doors with proper flashing and air sealing, and test every operable unit for smooth function and full lock engagement. Photos at each stage go into your project record.
5. 5
   Final inspection, walkthrough, and warranty delivery. We review every unit with you, demonstrate operation and cleaning, and provide the written warranty and final photo documentation. The 365-Day Done Right Promise applies: if it’s not done right, we make it right.
