Serving Pomona, CA and surrounding areas. (909) 729-4374
Your patio deserves to be usable in August, not just October. We build insulated, climate-controlled all season rooms that stay comfortable through Pomona summers and chilly winter nights.
All season rooms in Pomona, CA are fully enclosed, climate-controlled additions built for year-round use, with insulated walls, proper roofing, and heating and cooling connections. Most projects run two to five weeks of on-site construction after permits are approved.
Unlike a basic screened porch or a three season sunroom, an all season room handles Pomona's extremes on both ends - triple-digit summer heat and cold January nights. If your patio sits empty from June through September, this is the upgrade that changes that.
Pomona's inland location in the eastern San Gabriel Valley means outdoor spaces get punished by heat and UV from May through October. We design every all season room specifically for this climate, not for a coastal city with mild summers.
If your outdoor space becomes unusable from late May onward because of Pomona's intense heat, you are losing five to six months of use every year. An all season room with proper insulation and cooling lets you sit outside the main house even when it is 100 degrees at 9 a.m. The investment pays for itself in daily quality of life.
If you already have a screened porch or a basic sunroom and you avoid it from June through September because it turns into an oven, that structure is not doing its job. The same goes for a room that gets too cold on winter nights. These are signs your current setup lacks the insulation and climate control that a true all season room provides.
If your family has grown, you are working from home, or you need a quiet room that is not a bedroom or the main living area, an all season room can add meaningful square footage. Many Pomona homeowners use these rooms as home offices, playrooms, or casual dining spaces that require year-round comfort, not just mild-weather access.
If you have an older aluminum patio cover, a weathered wood pergola, or a cracked concrete slab that has been sitting unused, that space is already earmarked for improvement. Pomona's intense UV exposure and Santa Ana wind events accelerate wear on outdoor structures. An aging enclosure that looks tired is a natural starting point for upgrading to something fully enclosed.
Every all season room we build starts with the same core elements: a proper foundation or slab, insulated framed walls, an engineered roof, low-emissivity glass, and connections to your home's electrical and HVAC systems. From there, the scope depends on how you want to use the space. Homeowners looking for a seamless transition from indoors to outdoors often prefer a fully enclosed patio room layout with wide sliding or folding doors, while those wanting a brighter, more glass-forward feel tend to go with a layout closer to what you would find in a four season sunroom.
We also handle projects where an existing covered patio or partially enclosed space needs to be upgraded to true all season standards - better glass, added insulation, new HVAC connections, or a full structural upgrade. If your current space gets hot or cold before you want it to, we can assess what it would take to fix that without starting from scratch.
Best for homeowners starting from an open patio or bare slab who want a fully permitted, climate-controlled room built from the ground up.
Best for homeowners with an existing covered patio or basic screen room who want to upgrade to full insulation, proper glass, and year-round climate control.
Best for homeowners who have an older three season or non-climate-controlled sunroom that they want to convert into a room they can use all year.
Best for homeowners who want a custom layout, interior finishes, flooring, and a room that looks like it was always part of the house.
Pomona sits in one of the hottest inland pockets of Los Angeles County, where summer temperatures regularly reach 100 degrees F or higher and stay there for weeks. Coastal cities get marine layer relief - Pomona does not. That means the glass and insulation in your all season room have to work much harder than they would in a cooler part of the region. When we design a room here, we start with Pomona's heat load, not a generic inland California standard. Homeowners in Diamond Bar and Chino Hills face similar summer conditions and benefit from the same design approach.
Pomona also has a large share of homes built in the 1950s through 1970s, and attaching a new structure to an older home requires careful inspection of the existing foundation and roofline. A significant portion of these homes have original stucco exteriors and rooflines that need specific attention at the attachment point. We do that inspection before we give you a price - not after work has started. The permit process through Pomona's Building and Safety Division adds time to the schedule, but it also protects your investment and ensures the room shows up as legal square footage when you sell.
Call or submit the form and we will respond within one business day. We schedule a time to visit your home and look at the space in person before giving you any numbers, because the existing foundation and attachment point both affect scope and cost.
After the site visit, we prepare a written proposal covering the size and layout, the glass and framing system, how the room will be heated and cooled, and a detailed price breakdown. No pressure to sign - take the time to ask questions about any line item.
Once you sign, we submit plans to Pomona's Building and Safety Division. Plan review typically runs four to eight weeks. We manage the process and keep you updated throughout - this is a city timeline, not a contractor delay.
Once permits are approved, construction runs two to five weeks depending on size. A city inspector visits at key stages before the project closes. We walk through the finished room with you, explain any new systems, and address punch-list items before final payment.
We respond within one business day. No pressure, no obligation - just a straight answer about what is possible for your Pomona home.
We pull the permit from Pomona's Building and Safety Division on every project, no exceptions. A permitted all season room is legal, insurable, and adds to your home's value at resale. An unpermitted one is a liability. We have been handling Pomona permits since 2015.
We design for Pomona's climate specifically, not a generic California standard. That means insulated glass rated for this area's solar heat load, properly sized cooling, and thermally broken framing that does not conduct heat into the room. Ask us how we handle sustained heat - we have a specific, confident answer.
Southern California's earthquake risk means the connection between your new room and your existing home must be engineered for lateral movement. We build to California's seismic requirements, which is part of what the permit inspection verifies. A room that is properly anchored stays attached during a significant earthquake.
Older Pomona homes from the 1950s and 1960s sometimes have aging slabs or rooflines that affect scope and cost. We inspect your existing foundation and exterior walls before giving you a firm price. No surprises mid-project - you know exactly what you are getting into before you sign. Verified through the California Contractors State License Board.
Every all season room we build is the result of a design process that starts with your home's specific conditions - the foundation, the roofline, the sun exposure, and your intended use. That preparation is what separates a room you use every day from one you regret.
