Fontana summers push past 100 degrees for months at a time. Your outdoor space sits empty because of it. A properly built all season room or sunroom addition gives it back to you, year round.
San Bernardino Sunrooms & Patios is a sunroom contractor serving Fontana, CA, building all season rooms, sunroom additions, and patio enclosures for homeowners throughout the Inland Empire. We have been building in this region since 2015 and respond to every new inquiry within one business day.
With Fontana summers reaching 105°F and winter nights occasionally dipping below freezing in the northern neighborhoods, an all season room with real insulation and a dedicated HVAC unit is the only sunroom type that stays comfortable every month. It is the right investment for Fontana homeowners who plan to use the space daily rather than just a few weeks a year.
Fontana has a large number of ranch-style homes from the 1970s and 1980s with underused concrete patio slabs - ideal starting points for a full sunroom addition. We assess whether your existing slab and home structure can be worked with, which often reduces the total cost without cutting corners on the finished product.
Many Fontana homes have existing covered patios, particularly the two-story tract homes in North Fontana built in the late 1990s. Enclosing a covered patio adds a weatherproof room without the full cost of building from scratch, and we handle the city permit process so the addition is on record for your home.
For Fontana homeowners who want to extend the usable season without the cost of a full four-season build, a three season room gives comfortable use from late September through May - the months when the heat breaks and the Santa Ana winds die down. It costs less and still keeps bugs, dust, and wind out.
Fontana sits directly in the path of fall Santa Ana winds, and a well-built screen room with heavy-duty framing holds up to those gusts in a way that lightweight aluminum kits do not. A screen room is the most affordable way to make your backyard usable during the cooler months without enclosing it fully.
North Fontana has a mix of two-story homes with specific rooflines and architectural details that standard catalog sunroom kits do not match. A custom-designed room accounts for your home's exact proportions, exterior finish, and orientation so the addition looks like it belongs there, not like an afterthought.
Fontana sits at the western edge of the Inland Empire, where the flat valley floor meets the foothills of the San Gabriel Mountains. Summer temperatures here regularly exceed 100°F from June through September, and heat waves above 110°F are not unusual. The city also receives strong Santa Ana wind events each fall and winter, with gusts that can exceed 60 mph. Any sunroom built in Fontana needs to be designed with these conditions in mind - not just for comfort, but for the structural integrity of the room itself. Glass rated for heat rejection, frames that handle thermal expansion, and connections to the home that do not work loose under wind load are all non-negotiable.
The soil in much of Fontana contains a mix of sandy alluvial material and pockets of expansive clay - particularly as you move from the valley floor into the foothills of North Fontana. Clay soil swells when wet during winter rains and contracts during the dry summer, which puts stress on concrete foundations and any slab the sunroom sits on. Homes in North Fontana, many built in the late 1990s and early 2000s, are now reaching the age where foundations and exterior finishes need real attention. The City of Fontana's Building and Safety Division requires permits for all room additions, and their review process typically takes two to four weeks - something your contractor should factor into the project schedule from the start.
Our crew works throughout Fontana regularly, and we understand the local conditions that affect sunroom contractor work here. The housing stock we most often encounter divides into two distinct groups: the older ranch-style homes near the city center and along the older streets south of the 10 Freeway, and the larger two-story tract homes in North Fontana built in the late 1990s and 2000s. These two groups have very different structures, lot sizes, and construction details - and we approach each accordingly. Stucco exteriors are the norm across both, which affects how we tie new framing to the existing wall and how we finish the transition.
Fontana is one of the core cities of the Inland Empire and has grown significantly over the past three decades. The city stretches from the industrial corridors near the 10 Freeway all the way north to the foothills. Residents near the southern part of the city often deal with heavier truck traffic from the nearby warehouse and logistics corridor, while those in the northern neighborhoods enjoy quieter streets but hillier terrain. Whether you are near the Auto Club Speedway or up in the northern subdivisions, we know the neighborhoods and the permit process with the City of Fontana Building and Safety Division.
We also serve homeowners in nearby Ontario, CA to the west, which shares similar soil conditions and housing types. Homeowners in Rialto, CA to the east are also part of our regular service area.
Call or submit the contact form and we will get back to you within one business day. The first conversation covers what you want to use the room for, roughly where it would go, and any basic questions about your property before we schedule a visit.
We visit your Fontana property to assess the existing structure, foundation, and site conditions - including soil type and sun orientation. You get a written, itemized quote before any decision is needed, so you know exactly what you are paying for and can compare it against other estimates.
We prepare and submit plans to the City of Fontana Building and Safety Division on your behalf and schedule all required inspections. Once the permit is approved - typically two to four weeks - construction begins on a schedule we confirm with you before breaking ground.
After construction wraps, we walk through the finished room with you to confirm everything meets the scope we agreed on. The final city inspection closes the permit, and your new room is on the official record of your home - which matters when you sell or file an insurance claim.
We serve homeowners throughout Fontana, CA and respond within one business day. No pressure - just a conversation about what you want to build.
(909) 515-5768Fontana is one of the largest cities in San Bernardino County, with a population of roughly 214,000 according to the 2020 Census. The city grew rapidly over the past three decades, adding tens of thousands of residents since the 1990s, which produced a wide range of housing types across its neighborhoods. The older areas near the city center and south of the 10 Freeway are lined with single-story ranch homes from the 1970s and 1980s, while North Fontana is dominated by two-story tract homes from the late 1990s and 2000s - larger homes on wider streets with more outdoor space. The Auto Club Speedway, a well-known NASCAR venue in the southern part of the city, is one of Fontana's most recognizable landmarks and something most long-time residents know well.
About 60% of Fontana's housing units are owner-occupied, and many residents have lived in their homes for a decade or more - making this a city of long-term homeowners who invest in their properties. The northern neighborhoods sit at elevations above 1,500 feet in some areas, where the terrain rises toward the San Gabriel Mountains and drainage conditions differ from the flat valley floor. Fontana borders Rialto to the east and Ontario to the west - two other Inland Empire cities we serve regularly.
