Serving Westminster, CA and surrounding areas. (657) 364-0879
Westminster Sunrooms & Patios has served Orange County since 2019, and Cypress is a city our crew works in regularly. We build enclosed patio rooms, all season sunrooms, patio covers, and custom sunroom additions on the 1960s and 1970s tract homes that make up most of Cypress. Every project is fully permitted through the City of Cypress, built on a careful slab assessment, and designed to hold up through decades of hot summers, wet winters, and Santa Ana wind events.
Cypress homes from the 1960s and 1970s almost universally have a concrete patio slab out back - and in most cases, that slab has been sitting exposed and underused for decades. Enclosing it into a proper room is the most practical path to new living space on a Cypress lot without a major excavation or foundation project. Whether you want a screened room for spring evenings, a fully glass-in room for year-round use, or something in between, an enclosed patio room starts with what is already there. Read more about our enclosed patio rooms service, including how we handle slab assessment and framing on older Cypress properties.
Cypress summers regularly push into the mid-to-high 80s, and the area sees real rain from November through March. An all season room with insulated walls, low-emissivity glazing, and a dedicated mini-split is usable every month of the year - not just on mild spring evenings. For Cypress homeowners who want a room that functions like any other room in the house, this is the right option.
Before committing to a full enclosure, many Cypress homeowners start with a quality patio cover. An insulated panel or aluminum patio cover shades the backyard, extends outdoor living time through the long Cypress summers, and makes the eventual enclosure project simpler and less expensive because the structure is already in place. A well-built cover changes how much a backyard actually gets used.
Cypress tract homes from the same era often share similar floor plans and lot sizes, but each backyard sits differently and each homeowner uses their space differently. A custom sunroom accounts for your specific sun orientation, yard dimensions, and the way you plan to use the room. Custom does not mean expensive by default - it means the room is designed for your home rather than adapted from a generic plan.
Vinyl-framed sunrooms hold up well in northwest Orange County's combination of summer heat and periodic winter rain. Vinyl does not corrode, does not require repainting, and maintains its appearance after years of sun and moisture cycles. For Cypress homeowners who want a low-maintenance addition, vinyl framing is a reliable choice that avoids the repainting and resealing cycle that older aluminum or wood-framed systems require.
Some Cypress properties already have a covered patio - aluminum patio cover, wood lattice, or a solid-roof structure attached to the house. Converting that existing covered structure into a fully enclosed and glass-in room is often more cost-effective than starting from scratch because the roof and posts are already there. We assess the existing structure, determine what can be incorporated, and design the conversion around what is worth keeping.
Cypress was built out almost entirely between 1960 and 1980, and the housing stock reflects that - uniform construction methods, stucco exteriors, concrete slab foundations, and small to mid-size backyards on lots of 5,000 to 7,500 square feet. The concrete patio slabs on these homes have now been through 50-plus years of Orange County's wet-dry climate cycle. Clay soils that swell in winter and contract in summer push against slabs year after year. The result is the cracking, heaving, and settling that turns up on virtually every Cypress property we visit. A contractor who quotes an enclosed patio room without checking the slab first is setting up a project that could fail at the foundation before it is three years old.
The climate also puts real demands on the materials used. Cypress summers regularly hit the upper 80s, and Santa Ana wind events in fall and winter can push temperatures past 100 degrees Fahrenheit with single-digit humidity. That combination dries out caulk, warps wood trim, and cracks sealants that were installed without UV-resistant formulations. Stucco on Cypress homes that has not been refinished in 20 or more years often has hairline cracks along the roofline and around window frames - and any new addition needs to be waterproofed at the connection point before work begins. Getting those details right on the front end is what separates a room that still looks and functions correctly at year fifteen from one that starts showing problems in the second or third winter.
Our crew works throughout Cypress regularly, and permit applications for room additions go through the City of Cypress Building Division. We handle that process directly - drawing preparation, plan check submission, and inspection scheduling - without putting any of the permit coordination on the homeowner.
Cypress is a compact city of about 6.8 square miles, and once you know the landmarks it is easy to get around. Katella Avenue runs east-west through the southern part of the city and is the main commercial corridor. Cypress College sits in the northeast corner, and Los Alamitos Race Course is right on the southern border - a landmark almost every long-time Cypress resident knows. The residential neighborhoods run north of Katella Avenue, filling the rest of the city with the quiet, tree-lined streets of the 1960s and 1970s tract developments. We work in homes throughout all of those blocks.
We also serve homeowners in cities that border Cypress. If you know someone who needs sunroom work in Buena Park to the north or in Seal Beach to the southwest, we serve both of those communities as well.
Call us or fill out the contact form. We respond within one business day. We ask about your property - where in Cypress it is, the approximate patio size, and what you want the finished room to be used for - so we come to the site visit prepared.
We visit your Cypress property, check the existing slab for cracks, settling, or root intrusion, note the backyard orientation, and review the roofline connection. This visit is free and results in a written estimate with full scope, materials, permit costs, and a build timeline - no obligation.
We submit construction drawings to the City of Cypress Building Division and manage the plan check process. Once permits are issued, the crew arrives on the agreed start date. We protect your existing landscaping, fencing, and interior finishes throughout the build.
A City of Cypress inspector signs off on the completed room. We then walk you through the space together, answer any questions about the glass, the climate system, and the warranty, and close out the job with all permit documentation provided to you.

(657) 364-0879Cypress is a mid-size city of roughly 50,000 people in northwestern Orange County, incorporated in 1956 and built out almost entirely during the following two decades. The city sits at the intersection of the 605 and 22 freeways, which gives residents easy access to Long Beach, Anaheim, and the broader Los Angeles Basin. Cypress is compact - about 6.8 square miles - and fully built out, with no large undeveloped tracts remaining. Cypress College has been part of the community since 1966, and Los Alamitos Race Course on the southern border is a landmark that most long-term residents know well.
The city has a high rate of owner-occupancy and median home values that run well above national averages - a combination that reflects a community of long-term homeowners who invest in their properties. The vast majority of Cypress homes are single-family detached houses built on modest lots between 5,000 and 7,500 square feet, with stucco exteriors, concrete slab foundations, and attached garages. Those homes are now 50 to 60 years old and are at the stage where owners are making meaningful improvements rather than entry-level repairs. We also serve homeowners in neighboring communities, including La Palma to the east and Stanton to the northeast.
