An open patio sits empty five months a year in Simi Valley. An enclosed one gets used year-round. We build fully permitted screen and glass enclosures that protect you from the heat, bugs, wind, and UV without sacrificing natural light.
Patio enclosures in Simi Valley turn an existing outdoor patio into a protected, usable room by adding walls, windows, and a roof structure - typically sitting between a fully open patio and a full room addition. Most enclosures attach directly to the back of your home, using your existing slab and one existing wall, which keeps the project scope manageable. Installation usually takes one to three weeks once permits are approved.
If you are comparing a patio enclosure to a more substantial build, a custom sunroom gives you more flexibility in layout, height, and materials - but at a higher cost and longer timeline. A patio enclosure is the right choice when you have a solid existing slab, a clear idea of how you want to use the space, and a preference for a quicker, less disruptive project.
The California Contractors State License Board requires that any contractor working on an attached structure hold a current state license. You can verify a contractor's license, status, and complaint history on the CSLB website in about two minutes - it is a worthwhile step before signing any contract.
Simi Valley's inland heat regularly pushes past 95 degrees in summer, and a shaded, ventilated enclosure with the right glazing cuts that heat significantly. If you are spending summer months inside while your patio sits empty, the space is not working for you.
Simi Valley's sun is strong enough to bleach outdoor fabrics and crack furniture within a season or two. If you are replacing cushions every year, an enclosure would eliminate that recurring cost and protect everything inside it.
If you spend time cleaning grit and debris off your patio after every Santa Ana windstorm, an enclosure eliminates that task. Your outdoor space stays clean and usable regardless of what the wind carries.
Many Simi Valley homeowners want a home office, a playroom, or a casual dining room but do not want the cost or disruption of a full room addition. A patio enclosure uses your existing slab and delivers that room at a fraction of the cost.
We build both screen enclosures and glass enclosures, and the right choice depends on how you plan to use the space. Screen enclosures use mesh panels that keep insects out while letting air flow freely - they are the lighter, less expensive option and feel like an outdoor room. Glass enclosures use solid panels that can be opened or fixed in place, giving you real weather protection and the option to heat or cool the space. If you are not sure which direction fits your budget and goals, we walk you through the trade-offs during the free on-site estimate.
For homeowners who want a more fully finished living space, we also offer enclosed patio rooms with interior finishing, electrical rough-in, and more complete integration with the home. Both options are fully permitted through the City of Simi Valley, and both come with a detailed written proposal before any work begins.

Simi Valley sits in an inland valley that regularly sees summer temperatures above 95 degrees, and the sun angle is intense for most of the year. The glazing material you choose for your enclosure matters enormously here - low-heat glass or UV-filtering panels keep the space usable in July and August instead of turning it into an oven. A contractor who knows the local climate will steer you toward materials and roof overhangs designed for this specific sun exposure, not just what looks good in a catalog.
Most of Simi Valley's single-family homes were built between the 1970s and 1990s, which means existing patio slabs can be 40 or more years old. Older slabs may have settled unevenly or developed cracks. Homeowners in Chatsworth and West Hills face the same aging housing stock and share similar project considerations. The City of Simi Valley Building and Safety Division requires permits for any attached covered structure, and that permit review is also your insurance that the slab and structure meet current load standards.
We respond within 1 business day. The first call is a quick conversation - patio size, HOA status, and how you want to use the space. No pressure, just enough information to schedule a site visit that makes sense for both of us.
We visit your home, measure the patio, check the slab condition, and assess how the enclosure connects to your home's exterior wall. You receive a detailed written quote with every cost itemized - materials, labor, permit fees, and any slab work needed.
If your neighborhood has an HOA, we help prepare the submission package before the permit application goes to the City of Simi Valley. Plan for two to six weeks for permit review - sometimes longer if revisions are needed. We keep you updated throughout.
Once permits are approved, work begins within one to two weeks. Framing typically takes one to two days. Panel installation follows. The city inspects the work before we hand the space over to you - you receive signed permit documentation at final walkthrough.
We respond within 1 business day. No obligation - just a straightforward conversation about your project and a free on-site estimate at a time that works for you. Every quote is written and itemized so you can compare it side by side with other proposals.
(805) 261-5995Simi Valley enclosures need to handle gusts above 60 miles per hour. We design roof-to-wall connections and panel fastening to meet those wind loads - not just the minimum required by permit.
Every enclosure we build is permitted through the City of Simi Valley and documented in city records. An unpermitted enclosure can require costly removal before a sale closes. Ours never will.
Most Simi Valley patios are 40-plus years old. We assess the slab condition at the initial site visit and tell you honestly what - if anything - needs to be done before framing begins. No surprises after you have committed.
We help prepare everything your HOA needs - drawings, materials specs, and supporting documents. Contractors who work regularly in Simi Valley know what local review boards look for, and we put that experience to work for you.
