Precision Glendale Sunrooms & Patios builds sunroom additions, patio enclosures, and remodeled sunrooms for Alhambra homeowners - fully permitted, designed to work with older housing stock and compact lots, and backed by a crew that has served the San Gabriel Valley since 2019.

Many Alhambra homes have enclosed porches or screen rooms that were added in the 1960s and 1970s - single-pane glass, no insulation, frames that leak air in every direction. These rooms get abandoned rather than used. A proper sunroom remodel replaces the glass, re-seals the frame, and adds insulation so the space works year-round instead of collecting storage boxes.
Alhambra's small lots mean outdoor space is limited, and a covered patio that becomes unusable in summer heat or winter rain is wasted square footage. Enclosing that space with screens, glass, or a combination of both gives you a shaded, sheltered area without the permitting and cost of a full room addition built on a new foundation.
Homes in Alhambra built in the 1930s and 1940s were designed for smaller households and have floor plans that feel tight by today's standards. A sunroom addition connects to the existing structure and adds real livable square footage - a room for a home office, a playroom, or a comfortable sitting space - without the disruption of a full interior remodel.
For Alhambra homeowners who want more outdoor connection without the cost of a fully climate-controlled room, a three season sunroom is a practical middle ground. It is fully enclosed with screened or single-pane panels and comfortable from spring through fall - the nine months of the year when Alhambra weather is mild enough to enjoy an unheated enclosed space.
Vinyl frame sunrooms hold up well in the San Gabriel Valley climate and require less maintenance than painted wood or aluminum. For Alhambra homeowners who want a durable enclosed space without ongoing painting or recoating, vinyl frames are a practical material choice that works well with the stucco exteriors common throughout the city.
Alhambra's proximity to the San Gabriel River and its urban tree canopy means mosquitoes and other insects can be a nuisance in warmer months. A screen room around an existing patio or yard space keeps the outdoor air and views while blocking insects - a lower-cost option than full enclosure for homeowners who primarily want to use the space in spring and fall evenings.
Most homes in Alhambra were built between the 1920s and the 1950s - that means the concrete slabs, electrical panels, and structural connections are between 70 and 100 years old. A sunroom addition on a home from that era is not a simple bolt-on job. The existing foundation needs to be assessed before any new load is added to it. The electrical panel may be original or near-original, and adding lighting, fans, and outlets to a new room can push it past capacity. Any contractor who does not start with a structural assessment of the existing home is skipping a step that can turn a straightforward project into an expensive mid-construction problem.
The city's dense layout adds a practical complication: Alhambra lots are small, typically under 6,000 square feet, and homes sit close to each other. Side yard access for equipment and materials is often limited. The soil throughout much of the San Gabriel Valley is clay-heavy, which expands when wet and shrinks when dry - a cycle that can shift older slabs and crack concrete over time. Understanding these conditions before starting design saves homeowners from rework later.
Our crew works throughout Alhambra regularly, and we understand the local conditions that affect sunroom work here. We pull permits through the Alhambra Community Development Department and know that older homes in this city sometimes require pre-construction inspections before a permit is issued. We factor the permit review timeline into every project schedule so there are no surprises when construction is ready to begin.
Alhambra is a city of real neighborhoods. The Craftsman bungalows and Spanish Colonial Revival homes near Alhambra Park are some of the most distinctive housing in the San Gabriel Valley - charming homes with covered front porches, clay tile roofs, and original wood trim that require careful matching when any exterior work is done. The streets closer to Valley Boulevard and the commercial corridor are more mixed, with older multi-unit buildings alongside single-family homes on compact lots. Almansor Park on the west side of the city is a familiar landmark for most Alhambra residents.
We serve neighboring communities as well. Homeowners in Los Angeles to the west and San Gabriel to the east get the same permitted work and attention to older housing stock that we bring to every Alhambra job.
Call or submit the form and we respond within one business day. We get the basics about your home and project, then schedule a site visit at a time that works for you. No commitment needed at this stage.
We visit the property, walk the space, and assess the existing slab, structure, and electrical setup. For older Alhambra homes, this is where we identify anything that needs to be addressed before the sunroom work starts - and where we give you a realistic cost range that covers the full project, including permits and site prep. We try to be direct about cost at this stage so you are not surprised later.
Once you approve the scope and price, we prepare and submit permit applications to the City of Alhambra. Plan review typically takes three to six weeks. Construction begins after permit approval - framing, glazing, electrical, and finishing work typically take four to eight weeks depending on the size and complexity of the project.
We coordinate all required city inspections during construction. At completion, we walk through the finished room with you, cover any maintenance details, and confirm the work matches what was agreed. The room is yours to use the same day we leave.
We serve Alhambra and the surrounding San Gabriel Valley communities. We respond within one business day and bring honest pricing to every site visit.
(747) 609-3922Alhambra is a city of about 84,000 people on the western edge of the San Gabriel Valley, roughly 8 miles east of downtown Los Angeles. The city covers about 7.6 square miles, making it one of the more densely settled communities in the region. The housing stock is predominantly older - most homes were built between the 1920s and 1950s, with a notable concentration of Craftsman bungalows and Spanish Colonial Revival homes, especially in the neighborhoods near Alhambra Park. There is also a substantial mix of older multi-unit apartment buildings alongside the single-family homes. The city borders Monterey Park to the west, San Gabriel to the east, and Pasadena to the north. For more background on the city's history and geography, Wikipedia provides a thorough overview.
Valley Boulevard is the city's main commercial street, lined with restaurants and shops that reflect the city's diverse population. Almansor Park on the west side of the city is Alhambra's largest park, with a golf course, tennis courts, and a lake that most longtime residents know well. Homeowners here tend to invest in their properties - the median home value sits around $700,000 to $750,000, and many owners have held their homes for years. We serve neighboring areas too, including Rosemead to the south, where similar housing stock and lot sizes make for familiar working conditions.
