Fireplace installation in Ontario, CA - a fire that suits how you'll use it
Got a cold, unused firebox or no fireplace at all? We'll help you pick wood, gas or electric and fit it right.

What goes into putting in a fireplace in Ontario?
Fireplace installation in Ontario, CA means building a new fireplace into your house or setting an insert into the firebox you already have, so you end up with a fire that suits how you'll really use it.
Most calls start with a fireplace nobody lights, a drafty old brick box or a living room that's missing one, and the first thing I ask is what you want it for. Price mostly comes down to what's there now and what you pick, because building new masonry is a much bigger job than fitting a unit into a sound firebox, and a long gas line run or a new vent liner adds to it. The schedule turns on the same things, plus when your unit arrives, and if the chimney needs work first, I'll tell you and point you to chimney repair before anything else. My written estimate spells out what we'd do and what can stay as it is.
Why Ontario homeowners call us for fireplaces
I started this business to do masonry carefully instead of fast, so you can count on straight answers, a tidy site and nobody selling you a bigger fireplace than you'll use.
I come out myself
I look at every fireplace job in person, and I'm on site with our crew while the work gets done.
In business since 2023
We've been at it since 2023, and before that I spent years patching chimneys and walls at rentals around here.
Licensed and insured, inside your home
We're licensed and insured, which matters when someone's working on a fireplace in the middle of your living room.
We leave sound brick alone
If the brick and mortar around your firebox are sound, we leave them be, because tearing out good work just costs you money.
A tidy site while you live there
Years of working around tenants taught me to keep things tidy, because you're still living in the house while we work.
Fireplace options we install
Most people want a fireplace for the look and some extra warmth rather than as their main heat, so we pick wood, gas or electric from how you'll really use it.
What happens after you call about a fireplace?
We plan the job around your house and your days at home, so you know who's coming, what we're doing and when our crew will be there.

How much does a gas fireplace insert cost in Ontario, CA?
Across the US, a gas insert set into an existing masonry fireplace usually runs about $3,400 to $7,900 for the whole job, with the gas line and liner included. That's a national figure, not our price, and yours moves with how far the gas has to run and what shape your chimney's in. I'll give you your own number when I come out.
Which fireplace still works during a power outage?
A gas fireplace keeps running when the power goes out, so it's the one to pick if you want a fire during an outage. Electric costs less and goes almost anywhere, but it goes dark right along with the lights.
Can I put an insert in my factory-built fireplace?
Yes, but only an insert that was designed and tested for that particular unit, because a factory-built or zero-clearance fireplace isn't made to take just any insert. If you know the make and model of yours, have it handy when I come out.
How do I keep a gas fireplace safe after it's installed?
Give it room to breathe and plan on regular upkeep, because gas fireplaces need proper circulation and ventilation, and a good install still needs maintenance after it. The glass and frame can get quite hot to the touch, so think about kids and pets when you pick where it goes.
How do I get real heat from a fireplace?
Go with an insert or a gas unit, because an open fireplace is usually a very inefficient heater. Decorative logs give you the look of a fire without burning wood, but they aren't meant to put out much heat.
What does installing a gas fireplace insert involve?
In one typical install, the crew cleans the firebox and flue, adds an outlet inside the fireplace, runs a gas line, drops a vent liner from the top of the chimney, caps it and sets the insert. In that walkthrough, inspections come before the final hookup, and the new gas line gets a pressure test before an inspector signs off. If you have a masonry chimney, it's fair to ask whoever you hire whether a certified installer will make sure the flue liner goes in right.
Fireplace installation in Ontario and the cities around it
If you're leaning toward wood, know that the regional wood-burning rule, as its latest notice describes it, calls for cutting back on wood fires on No-Burn days, when fine particle pollution is forecast to go over a set limit, and those days fall from the start of November through the end of February. That's the same stretch you'd most want a fire, so I talk it through with anyone choosing wood over gas. The rule also bars burning anything that isn't meant as fuel and selling unseasoned wood, so plan on seasoned firewood.
We're based in Ontario and work across the cities around it, and we run into the same older brick fireboxes and metal units on jobs in Upland and Pomona, plus plenty of other cities nearby. Most of them are worth keeping, so we start with what's there.
