Supreme Ontario Deck and Fence provides composite deck installation, custom deck design, pergola builds, and fence work to Montclair homeowners. We are a licensed contractor serving this city and the surrounding Inland Empire, and we respond to every new inquiry within one business day.

Montclair summers hit 95 to 100 degrees regularly, and that sustained UV exposure fades natural wood stains faster than most homeowners expect. Our composite deck installation uses boards engineered to hold their color without annual sealing, making them a practical, low-maintenance choice for the Montclair climate.
Montclair homes built between the 1950s and 1980s often have modest backyards with existing concrete slabs that need to be worked around or replaced. A custom design accounts for your specific yard dimensions, ground conditions, and how you actually want to use the space.
Direct afternoon sun makes many Montclair backyards uncomfortable for most of summer. A pergola with shade fabric or louvered panels adds usable covered space without a full room addition, and it works with any deck surface you already have or plan to build.
Many Montclair homes from the postwar decades have older wood decks that have been through decades of heat and seasonal soil movement. Soft boards, wobbly posts, and cracked ledger connections are common findings in homes of that age, and catching them early costs far less than a full rebuild.
Santa Ana winds regularly push past 50 mph in the Montclair area, and wood fence posts anchored in alluvial soil are prone to shifting over time. Vinyl fencing holds its appearance without painting and stays anchored more consistently in the type of loose, granular soil common in this part of the Inland Empire.
Montclair gets its rain primarily in winter, and an attached patio cover protects your deck surface and outdoor furniture through those months while also giving you shade during the intense summer heat. It is one of the most practical upgrades for Montclair backyards in terms of year-round usability.
Montclair sits at the eastern edge of the Los Angeles metro area, at the base of the San Gabriel Mountains at roughly 1,100 feet in elevation. Most of the city's residential neighborhoods were built between the late 1940s and the early 1980s, which puts the bulk of the housing stock at 40 to 75 years old. Homes in this age range are at the stage where roofs, plumbing, exterior surfaces, and outdoor structures all tend to need real attention at the same time. The alluvial soils common in this area, loose sandy material washed down from the mountains over centuries, shift and settle in ways that put stress on concrete slabs, fence posts, and deck footings over time.
Montclair's climate adds its own pressure. Summers regularly push into the mid-to-upper 90s, and the city's inland position means no coastal cooling effect to moderate afternoon temperatures. That sustained heat and UV exposure degrades wood stains, dries out caulking around ledger boards, and causes composite materials of lower quality to warp. Fall brings Santa Ana wind events that test every fence post and railing connection in the city. A deck builder working regularly in Montclair plans for this from the start - in material choices, footing depths, and how structures are anchored.
Our crew works throughout Montclair regularly, and we understand the local conditions that affect deck and fence work here. Permits for residential decks are submitted to the City of Montclair Building and Safety Division. Knowing how to prepare a complete submittal package the first time reduces back-and-forth that can add weeks to a project.
Most Montclair homes we work on are one-story ranch-style designs on modest lots, usually 5,000 to 7,000 square feet, with a concrete patio slab in the backyard. Many of those slabs are cracked or have shifted with the soil over the decades. The city is laid out on a grid with Monte Vista Avenue running through the heart of the residential neighborhoods, and most of the housing we encounter is within a few blocks of that central corridor. Homes near Montclair Place tend to have tighter lot widths than those closer to the foothills.
Montclair borders Pomona to the east and sits close to Ontario to the west. We serve all three cities, so homeowners near any of those boundaries are well within our regular service area.
Reach us by phone or through the estimate form and we will respond within one business day. We ask a few questions about your project so the site visit starts with the right context, not a blank slate.
We visit your Montclair property, measure the space, assess soil and drainage conditions, and review any existing structure that needs to be worked around or removed. You receive a written, itemized estimate before any commitment is made.
For permitted work, we submit plans to the City of Montclair Building and Safety Division and coordinate inspections at the footing and framing stages. Once approved, construction typically takes three days to two weeks depending on the scope.
We walk through the finished project with you before we close out. Any adjustments are handled then, not after we have left the site. You get a clean workspace and clear documentation of what was built and how.
No pressure. We will review your project, visit the site, and give you a written estimate. Montclair homeowners are welcome to call or use the form below.
(909) 738-1084Montclair is a city of about 38,000 people in San Bernardino County, positioned between Ontario to the west and Pomona to the east along the 10 Freeway. The city grew rapidly in the postwar decades, and its residential streets reflect that era: mostly one-story stucco homes on grid-pattern blocks with modest yards and mature trees. The majority of homes are owner-occupied, giving the neighborhoods a stable, long-term feel. Montclair Place, the city's regional shopping mall on Central Avenue, has been a community anchor for decades and serves as the central reference point most residents use when describing where they live in the city.
The city also has a mix of apartment complexes and multi-family buildings, particularly along Central Avenue and Monte Vista Avenue, which run through the commercial core. The Montclair Metrolink station connects commuters to downtown Los Angeles and other Inland Empire cities. Neighboring Upland lies to the north, and Pomona borders the city to the east - both communities share the same general climate, soil conditions, and housing characteristics that we see throughout Montclair.
