Mission Sunrooms & Patios has been serving Mission homeowners since 2017, building sunroom additions, patio enclosures, and screen rooms using materials and techniques that hold up in South Texas heat. We reply within one business day and provide free written estimates.

Mission homeowners are adding sunrooms to gain climate-controlled living space without the cost of a full home addition. A properly built sunroom addition sits on a permitted foundation, uses insulated glass rated for South Texas UV exposure, and ties into your existing roofline so the new room feels like part of the original house.
In Mission, where summer temperatures stay above 100 degrees for months, a four-season sunroom with a dedicated mini-split system is the only way to use the space comfortably year-round. These rooms are fully insulated and sealed, making them a true extension of your air-conditioned living area even at the peak of summer.
Mosquitoes and gnats are a real problem in Mission, especially near the Rio Grande and during wet seasons. A screen room keeps insects out while letting the evening breeze in, and it costs significantly less than a fully enclosed sunroom if budget is a priority.
Many Mission homes have covered patios that homeowners want to convert into usable, weather-protected rooms. A patio enclosure adds walls and glazing to the existing structure, turning a basic covered slab into a room that functions through spring, summer, and fall without requiring a full sunroom budget.
Homes in Mission vary from compact in-town lots near Conway Avenue to large corner lots in newer north-side subdivisions. A custom sunroom is designed to fit the specific footprint, roofline, and exterior material of your house rather than forcing a generic kit to work where it does not belong.
A patio cover is one of the most practical investments a Mission homeowner can make given the intense sun. It shades your outdoor slab, protects exterior walls from direct UV exposure, and makes the yard usable for morning coffee or evening gatherings even in July when standing in direct sun is not an option.
Mission sits in one of the hottest parts of the continental United States, where summer temperatures routinely exceed 100 degrees Fahrenheit and UV exposure is extreme year-round. Standard sunroom glazing products designed for milder climates can fail quickly here. Low-E glass rated for South Texas conditions, combined with proper ventilation or a dedicated HVAC system, is not optional in this climate - it is the baseline for a room that will actually be usable.
The clay-heavy soil underneath most Mission properties swells when wet and shrinks during dry spells, which puts ongoing stress on concrete slabs and footings. Sunroom foundations that are not engineered with this in mind can crack, shift, or separate from the main house structure within a few years. We account for local soil behavior during every design and permit submission, because a room that shifts is a room that leaks.
Mission Sunrooms & Patios has been working in Mission since 2017, and our crew pulls permits regularly through the City of Mission Building Inspection Division. We know the plan review timeline, what inspectors look for on sunroom additions in this municipality, and how to build foundations that satisfy local requirements given the expansive clay soil throughout Hidalgo County.
Mission is a city with distinct neighborhoods that require different approaches. Older homes near downtown and along Conway Avenue often have stucco or brick exteriors and mid-century rooflines that need careful tie-in work. The newer subdivisions going up on the north side of the city near Bentsen Road are built on larger lots with more room for additions, but the soil conditions are just as challenging. We have worked on both types of properties throughout the city.
We also serve homeowners in neighboring communities. If you are in Palmview just west of Mission, or in other nearby areas throughout Hidalgo County, our team covers the full region and applies the same local building knowledge to every project.
Reach us by phone or through the contact form on this page. We reply within one business day. You do not need to know exactly what you want yet - describing the problem or the space you have in mind is enough to get started.
We visit your Mission property, measure the space, check the existing structure, and review any relevant permit requirements with you. There is no charge for the estimate, and we give you a written quote before any work is scheduled.
We file the building permit with the City of Mission and begin ordering materials once it is approved. Most sunroom additions in Mission take between two and six weeks to complete once the permit is in hand, depending on the size and type of room.
After construction, the city inspector reviews the work and signs off on the permit. We then walk through the finished room with you, answer questions, and confirm everything meets your expectations before we leave the job site.
We reply within one business day, estimates are free and written, and we handle the permit process from start to finish. Call us or fill out the form to get started.
(956) 391-1529Mission is a city of around 84,000 people in Hidalgo County, situated just a few miles north of the Rio Grande in the heart of the Rio Grande Valley. The city calls itself the Home of the Texas Ruby Red Grapefruit and hosts the annual Texas Citrus Fiesta every January. Housing in Mission ranges from mid-century brick and stucco homes near the downtown core to large newer subdivisions on the north and west sides of the city. About 65 percent of occupied housing units are owner-occupied, which means most residents are long-term property owners with a real stake in maintenance and improvement.
Landmarks like Bentsen-Rio Grande Valley State Park to the south and Veterans Memorial Stadium make Mission recognizable throughout the Valley. The city shares its metro area with McAllen, Edinburg, and a string of smaller communities along US-83. Homeowners near Mission often work with contractors who also serve Palmview to the west, where housing conditions and building requirements are similar.
Enjoy your sunroom year-round with full climate control and insulation.
