Enclosed patio rooms
A more affordable way to add permanent covered living space to your backyard, without the full HVAC integration of an all season room.
Learn MoreYour backyard sits empty half the year because no open patio can handle Inland Empire heat. We build all season rooms in Upland designed to stay comfortable from the hottest July afternoon to the coldest January night.

All season rooms in Upland, CA are fully enclosed additions with insulated walls, high-performance glass, and a real climate control system, so the room stays comfortable year-round rather than just in mild weather. Most projects take eight to fourteen weeks from permit approval to completion, with construction itself running four to six weeks.
The difference from a standard sunroom matters most in Upland. A sunroom is often built with minimal insulation and no dedicated cooling - fine for coastal California, but a problem when summer temperatures push past 100 degrees in the Inland Empire. An all season room is built to a higher standard so the interior temperature tracks your thermostat, not the weather outside. Many Upland homeowners who already have a sunroom eventually upgrade it to a true all season room for exactly this reason.
If you are also evaluating a simpler option, our enclosed patio rooms page covers the lower-cost alternative that still beats an open patio. For homeowners who want the highest-specification build available, our four season sunrooms page walks through what that tier of construction includes.
If you stop going outside from late May through October because Upland heat makes it unbearable, your outdoor space is working against you. A properly cooled all season room can turn that dead zone into the most-used room in your home. Staying out of your backyard for five months a year is a clear sign the current setup is not doing its job.
Santa Ana winds push dust and debris across open patios for days at a time, making them miserable even when the temperature is pleasant. If your covered patio is too hot in summer, too cold in winter, and covered in grit after every wind event, enclosing it as an all season room solves all three problems. You keep the same footprint and gain a room you can actually use.
If you already have a sunroom or patio enclosure that turns into a greenhouse in summer and a cold box in winter, it was likely built without proper insulation or climate control. Upgrading it to a true all season room - with insulated glass, proper wall insulation, and real HVAC - can transform a room you avoid into one you use every day. Half-measures show up fast in Upland's extreme temperatures.
If your family needs more room but a full addition feels too expensive or disruptive, an all season room is often a faster and less invasive way to add usable square footage. It does not require the same level of structural work as expanding a kitchen or adding a bedroom, and the timeline is typically shorter. Many Upland homeowners find this is the right middle ground between doing nothing and a full-scale remodel.
Every all season room project starts with a concrete or reinforced foundation, insulated framing, and glass units rated for the Inland Empire climate. We handle the full scope - from permit drawings to city inspections to final walkthrough. For homeowners who want to go further, we can connect your new room to your home's existing HVAC system or install a dedicated mini-split so the space is climate-controlled on its own.
We also work with homeowners who already have a structure that is not performing well. If your existing enclosed patio room gets too hot in summer or too cold in winter, upgrading the glass and adding proper insulation and climate control is often faster and more affordable than starting over. For homeowners who want the most feature-rich option, our four season sunrooms represent the highest specification we build and include every element that makes a room genuinely usable 365 days a year.
Ties into your home's existing heating and cooling system for seamless temperature control. Suits homeowners who want the new room to feel identical to the rest of the house.
A dedicated ductless unit handles heating and cooling independently from your main system. Best for larger additions or homes where extending existing ductwork is not practical.
Insulated, low-e glass units rated for Inland Empire heat loads. The right choice if your project is in a south- or west-facing orientation.
Transform an underperforming sunroom or patio enclosure into a true all season room with upgraded insulation, glass, and climate control. Suits homeowners who have the bones but not the comfort.
Upland sits in the Inland Empire at the base of the San Gabriel Mountains, where summer temperatures regularly climb above 100 degrees and the air stays dry for months at a time. Standard outdoor living spaces - open patios, screened porches, basic sunrooms - become unusable from late May through early October. Building to coastal California standards is not enough here; the glass, insulation, and cooling system in an all season room need to be specified for Inland Empire conditions, not San Diego weather. California also has seismic requirements that apply to any permanent room addition, meaning the framing and foundation connections must be built to handle earthquake loads in addition to the structural demands of a normal addition.
The need for climate-resilient living space is felt across our service area. Homeowners in Rancho Cucamonga face the same Inland Empire heat, and we work on all season room projects there regularly. We also serve Fontana homeowners dealing with the same summer conditions and the same seismic construction requirements that apply throughout San Bernardino County. Wherever you are in the area, the principles are the same: build it right for this climate, pull the permits, and it will perform.
We ask a few questions over the phone - room size, location on your property, and budget range - to make sure the project is a good fit before anyone drives to your house. We reply within one business day and can usually schedule an in-home visit within the week.
We measure the space, review your existing foundation and exterior wall, and talk through design options with you. You leave with a written estimate, a clear sense of scope, and no obligation to move forward.
We submit the permit application to the City of Upland and, if needed, prepare the drawings for your HOA's architectural review. Permit approval typically takes two to four weeks - this wait is normal and expected.
Work begins with foundation and framing, then moves to insulated walls, roof, windows, and systems. City inspectors visit at key stages. We coordinate all inspections so you never have to make a call to the building department.
We reply within one business day, give you a written estimate at no charge, and never pressure you to decide on the spot.
(909) 755-8782Our contractor's license is active and verifiable on the California Contractors State License Board website in about thirty seconds. Licensing means passing state exams, carrying required insurance, and being held accountable if something goes wrong.
Verify on CSLBWe pull every permit through the City of Upland's Building and Safety Division before a single board goes up. You receive copies of all permit documents at project completion - the documentation that matters when you sell.
We specify insulated glass and cooling equipment rated for Inland Empire heat, not coastal temperatures. A room that cannot handle July in Upland is not an all season room - it is a three-month room.
Many Upland neighborhoods near the 210 freeway and the foothills have HOAs with strict architectural review requirements. We have prepared submissions for Upland-area HOAs and know what their review committees typically need to approve a project without back-and-forth.
We have been building permitted room additions in Upland and the surrounding Inland Empire long enough to know what the city inspectors look for and what local HOAs typically require. That local experience shortens your timeline and reduces the chance of a costly revision mid-project.
