Supreme Ontario Deck and Fence builds custom decks, pergolas, fences, and patio covers for Upland homeowners. We are a licensed contractor serving this city and the surrounding Inland Empire, and we respond to every new project inquiry within one business day.

Upland has a mix of mid-century ranch homes near Euclid Avenue and larger newer homes up near the foothills - no two backyards are exactly the same. A custom deck design and build takes your actual yard, your actual lot grade, and how your family uses outdoor space as the starting point, rather than fitting your property into a standard package.
Upland summers push past 100 degrees for weeks at a time, and that heat makes a lot of backyards unusable during the prime afternoon hours. A pergola with shade cloth or louvered panels turns direct sun into filtered light and gives your family a genuine outdoor room - without the cost of a full room addition.
Upland's high UV index through most of the year fades wood stains faster than most homeowners expect. Composite decking holds its color without annual sealing and does not crack or splinter under the sustained heat of Inland Empire summers - a practical advantage on a home that sees full sun exposure most of the year.
Many of Upland's older neighborhoods have original wood fencing from the 1960s and 1970s that has reached the end of its service life. A new wood privacy fence gives these properties back a clear boundary and proper screening without a large price premium - and it fits naturally into the character of Upland's established residential streets.
A solid patio cover changes how Upland homeowners use their outdoor space through summer - keeping the deck surface cooler, protecting outdoor furniture from UV damage, and making the space more comfortable for the entire family during the longest days of the year.
A large share of Upland homes were built in the 1950s through 1970s, and if a deck was added during or shortly after that era, it may have footings that were never engineered to match Upland's expansive clay soils. Regular inspection of older decks in Upland is worth doing - what looks like surface wear is sometimes a structural issue underneath.
Upland sits right at the foot of the San Gabriel Mountains, and that position shapes almost everything about how outdoor structures perform here. The expansive clay soils that run through much of the Inland Empire are present throughout Upland, and they move in a predictable seasonal cycle - swelling when winter rains arrive, then contracting as the dry season sets in. That back-and-forth is what causes deck posts to drift, patio slabs to crack, and fence posts to lean over time. A deck builder who works in Upland regularly designs footings with enough depth and bearing area to ride out that soil movement without the structure shifting.
The housing stock adds a layer of complexity that a contractor unfamiliar with Upland might miss. A large share of homes in the city were built between the 1950s and 1970s - which means many properties have original flatwork, aging fence posts, and in some cases legacy concrete footings that need to be assessed before any new deck work goes on top of them. The newer homes up near the foothills in north Upland were built mostly in the 1980s through 2000s, and those tile-roofed stucco homes often have HOA rules that govern deck materials and fence heights. Knowing which part of Upland you are in changes how a project is planned and permitted from the start.
Our crew works throughout Upland regularly, and we submit permits directly with the City of Upland Building and Safety Division for every project that requires one. We know what the local plan review process looks like for deck and fence submittals, and we prepare packages accordingly - which reduces correction cycles and keeps project timelines predictable.
Upland has a distinct residential character that sets it apart from neighboring cities. The tree-lined streets near Euclid Avenue - one of the most recognizable boulevards in the Inland Empire - run through neighborhoods with mature landscaping and older homes that have their own set of site conditions. The foothills neighborhoods to the north, closer to the base of the San Gabriel Mountains, have newer construction and different drainage patterns. We work in both regularly and understand what each part of town requires.
Upland borders Rancho Cucamonga to the east and sits just north of Ontario. Homeowners near any of those city lines get the same crew and the same local service from us.
Call us or submit your information through the estimate form and we will follow up within one business day. A few quick questions about your property help us come prepared for the site visit rather than asking you to describe everything twice.
We visit your Upland property, assess the existing site conditions including slope, soil, and any existing structures, and give you a written itemized estimate at no charge. We explain the cost breakdown so you understand what you are paying for - not just a total number.
We handle permit submittal with the City of Upland and coordinate city inspections as required. Once permits are approved, the build phase typically takes three days to two weeks - we keep you updated throughout so there are no gaps in communication.
Before the project closes out, we walk you through everything that was built. If anything needs adjustment, we take care of it during that walkthrough - not after you have already signed off on the work.
We serve Upland homeowners from Euclid Avenue to the foothills. Call or submit your details and we will respond within one business day.
(909) 738-1084Upland is a city of roughly 80,000 people in San Bernardino County, sitting directly at the base of the San Gabriel Mountains. The city is sometimes called the "City of Gracious Living" - a nickname that reflects the tree-lined streets, mature landscaping, and well-kept residential character that makes Upland feel different from many neighboring Inland Empire cities. The most recognizable street in the city is Euclid Avenue, a wide, tree-lined boulevard running north to south through the heart of the city. The area near the historic downtown and the Upland Train Depot - built in 1906 - is where many of the city's oldest homes are concentrated. These mid-century ranch homes on modest lots have a character that newer subdivisions simply do not have.
The northern part of Upland, closer to the foothills and near the border with Rancho Cucamonga, has newer construction from the 1980s through the 2000s. These homes sit on slightly larger lots, tend to be two-story, and in many cases offer direct views of Mount Baldy - the tallest peak in the San Gabriel Mountains and a landmark visible from almost everywhere in the city. Upland has a higher homeownership rate than many surrounding cities, and median home values run higher than the San Bernardino County average - which reflects a community of homeowners who invest in keeping their properties in good shape. Homeowners near the border with Claremont to the west and Rancho Cucamonga to the east can count on the same crew serving all three cities.
