Serving Ontario, CA and surrounding areas. (909) 738-1803
Whether you want a gas fireplace for quiet evenings or a full masonry build that lasts decades, we handle permits, seismic reinforcement, and the city inspection so you don't have to.
Fireplace installation in Ontario, CA involves choosing the right type of unit for your home and lifestyle, pulling permits through the city, reinforcing your foundation and structure as needed, and completing a licensed city inspection before the job closes - most gas installations finish in one to two weeks from permit approval, while full masonry builds take three to seven days of active work plus curing time.
Most homeowners who call us are at one of two stages: they have been wanting a fireplace for a while and are finally ready to move forward, or they have an existing fireplace that came with the house and has never been properly inspected. Ontario's mild winters make a fireplace more of a lifestyle choice than a heating necessity - but it is a choice that adds real comfort and real value to your home. The South Coast Air Quality Management District enforces burn-day restrictions on wood-burning units, which is why many Ontario homeowners choose gas over wood.
If you are also considering updating an existing fireplace surround or adding a stone feature wall, we often pair fireplace installation with stone veneer installation to give the finished result a cohesive, custom look. The Chimney Safety Institute of America recommends that any new or existing fireplace be assessed by a qualified professional before use.
Ontario evenings drop into the 40s and 50s from November through February. If you find yourself reaching for a blanket every evening in winter or avoiding your main living area after dark, a fireplace can change how you use that room entirely. Many Ontario homeowners describe it as the single upgrade that made their home feel more livable year-round.
If your home came with a fireplace that was built before 1990, you may not know whether it is safe to use. Visible cracks in the firebox, mortar that crumbles when pressed, or a damper that does not open and close smoothly are signs the fireplace needs professional attention before it is used again. In some cases, a full rebuild is safer and more cost-effective than repeated repairs.
Smoke coming into your living room instead of going up the chimney is a clear sign something is wrong - with the chimney height, its liner, or the damper. This is not a minor inconvenience. It means combustion gases are entering your home. Stop using the fireplace and call a professional to assess whether a repair or a full reinstallation is needed.
Ontario's real estate market is competitive, and a well-built gas fireplace is consistently cited as a feature that attracts buyers and supports higher asking prices. If you are already doing a living room or kitchen remodel, adding a fireplace at the same time is often more cost-efficient than doing it as a standalone project later, when walls are already open.
We install gas fireplaces and custom masonry fireplaces built from brick or stone. For gas units, we work with a licensed plumber or gas fitter to extend the gas line if your home does not already have one running to that room - that coordination is included in how we manage the project, so you are not making separate calls to separate contractors. We pull the permit through the City of Ontario, manage the plan review process, and schedule the city inspection. You do not have to navigate any of that on your own.
For full masonry builds, we also pair the fireplace with matching outdoor kitchen masonry if you want to extend the project to your outdoor space. Every masonry fireplace we build in Ontario is reinforced with steel rebar to meet California's seismic requirements - this is not optional, and any contractor who is not including it is creating a safety problem for you down the road.
For homeowners who want ambiance and warmth without wood-burning restrictions - the most practical choice for Ontario's climate and air quality rules.
For homeowners who want a brick or stone fireplace built from scratch - a longer-lasting, higher-investment structure that adds significant character to the room.
For existing fireplaces with cracked fireboxes, failed mortar, or damaged chimney sections that need to be rebuilt safely before use.
For homes adding a new fireplace that requires a new chimney run or a relining of an existing flue to meet current code.
We handle the City of Ontario permit application, plan review, and city inspection coordination from start to finish.
All masonry fireplaces we build include steel rebar reinforcement as required by California's building code for seismically active areas.
Two factors shape almost every fireplace installation conversation we have with Ontario homeowners. The first is the South Coast Air Quality Management District's wood-burning restrictions. On days when air quality is poor - which happens regularly during Inland Empire winters - wood burning is prohibited. That rule does not apply to gas fireplaces, which is one reason gas has become the dominant choice among Ontario homeowners installing a new unit. The second factor is seismic exposure. Ontario sits in an active seismic zone, and California's building code requires masonry fireplaces to be reinforced with steel rebar and anchored to flex during an earthquake rather than crack and collapse. This requirement adds some cost compared to fireplace installation in lower-risk states, but it is a genuine safety requirement that protects your home and everyone in it.
A large portion of Ontario's housing stock was built between the 1970s and 1990s on slab foundations. We work regularly in Rancho Cucamonga and Chino, where similar slab-foundation homes are common, and we bring that experience to every Ontario project. During the estimate visit, we assess your foundation before recommending a fireplace type - if reinforcement is needed, we tell you upfront with a written cost, not a surprise charge halfway through the job.
Call or submit a form and we will be back to you within one business day. We will ask what type of fireplace you are interested in, where in the home you want it, and whether you have an existing fireplace or are starting from scratch.
We visit your home to assess the space, check your foundation and walls, and determine what the installation will actually involve - including whether seismic reinforcement is needed. After the visit, you receive a written estimate with a clear breakdown of labor, materials, and permit fees.
Once you approve the estimate and sign a contract, we submit the permit application to the City of Ontario's Building and Safety Division. This typically takes one to three weeks. You do not make any calls to the city - we manage all of it.
Once the permit is approved, the installation begins - one to five days depending on the type of fireplace. After completion, the city inspector visits to verify the work meets Ontario's building requirements. We schedule that appointment and are present for it. After it passes, we walk you through how to use your fireplace safely.
We respond within one business day, handle the City of Ontario permit process, and give you a written estimate before any work begins.
(909) 738-1803California requires masonry contractors to hold an active Contractors State License Board license. You can verify ours in about two minutes on the CSLB website. A licensed contractor is also covered by required insurance - which matters when the work involves structural changes to your home.
Every masonry fireplace we build in Ontario is reinforced with steel rebar as required by California's building code for seismically active areas. This is not an optional upgrade - it is how every fireplace should be built in the Inland Empire. If a bid seems unusually low, ask specifically whether seismic reinforcement is included.
Pulling a permit through Ontario's Building and Safety Division involves paperwork, plan review, and inspection scheduling. We manage every step of that process on your behalf. When the inspector signs off, you have a fully documented, city-approved fireplace that protects your home's value and your insurance coverage.
Many Ontario homes built on slab foundations need reinforcement before a full masonry fireplace can be installed. We assess your foundation during the estimate visit and tell you honestly what is needed - with a written cost - before we sign a contract. No surprise charges halfway through the job.
When you hire OT Ontario Masonry, you are working with a contractor who knows Ontario's permit process, its seismic requirements, and its housing stock. That knowledge shows up in the finished result - and in the fact that you will have a city-verified record that your fireplace was built safely.
