Fireplace Insert Installation

Fireplace Insert Installation in Los Angeles

An open fireplace sends most of its heat straight up the chimney. An insert turns that same fireplace into a sealed, efficient heater that actually warms the room. We size it, line the flue and install it properly, gas or wood.

    An open fireplace loses most of the heat it makes

    A traditional open fireplace pulls warm room air up the chimney along with the smoke, so a lot of nights it takes more heat out of the house than it puts in. An insert seals the opening and pushes the heat back into the room, which is the whole reason to fit one.

    A fireplace insert is a sealed firebox, gas or wood, that fits into your existing masonry fireplace and turns it into an efficient heater. Installing one means sizing it to the opening, lining the flue to suit it, and connecting it so it runs safely and cleanly.

    The insert slides into the fireplace you already have and closes off the big open throat that lets heat escape. Instead of an open fire that mostly warms the chimney, you get a controlled, glass-fronted fire that radiates heat out into the room and keeps burning steadily.

    There are a few kinds. A gas insert lights with a switch or remote and needs a gas line and venting. A wood insert burns logs far more efficiently than an open fire and needs a proper liner. Both come in sizes and styles to suit the fireplace and the look you want.

    The part people underrate is that an insert is not a drop-in appliance. It has to be matched to the size of the firebox, vented up a correctly sized liner, and connected to gas or electricity to code. Get that right and it is clean, efficient and safe. Get it wrong and it draws poorly or is a hazard.

    That is the work we do. We measure the fireplace, help you choose an insert that fits and suits the room, line the flue to match it, and make the gas or electrical connections properly, so it is ready to run the day we leave.

    Why people fit one

    The reasons an insert is worth it

    Tell us how you use the fireplace and what you want from it. That points to whether an insert makes sense and which kind.

    Efficiency

    Your fireplace looks nice but barely heats the room

    An open fire feels warm right in front of it and does little for the rest of the room, while pulling heated air up the chimney. If you light fires for warmth and are not getting it, that is the classic case for an insert.

    A sealed insert holds the fire behind glass and radiates the heat outward, so the same fireplace actually warms the space instead of the sky.

    Convenience

    You want a fire at the flick of a switch

    Hauling and stacking wood, laying and lighting a fire, and cleaning ash afterward is more than a lot of people want. A gas insert gives you a real, controllable flame instantly, with no wood and no mess.

    We fit gas inserts with the gas line, venting and controls done properly, so it lights on a switch or remote and runs cleanly.

    Burning wood well

    You love a wood fire but want it to actually work

    If you want the real thing, wood, but without the waste and the smoke of an open hearth, a wood-burning insert burns far more completely and throws real heat while it does.

    We size a wood insert to the fireplace and line the flue to suit it, so it drafts properly, burns clean and heats the way it should.

    Replacing an old unit

    An old insert that has stopped working or looks dated

    Inserts age. Older gas units fail or fall out of favor, and a tired insert can look dated in an otherwise updated room. Swapping it is a straightforward way to modernize the fireplace.

    We pull the old unit, check the flue and connections, and fit a new insert that suits the fireplace and the room today.

    A cold or unused room

    A fireplace you never light because it is a hassle

    Plenty of fireplaces sit unused because an open fire is too much work or too drafty to bother with. An insert turns that dead corner into a heat source you will actually use on a cold evening.

    We will talk through gas versus wood for how you live, and fit the one that means the fireplace earns its place again.

    The part people get wrong

    An insert is only as good as the install behind it

    The insert itself is the easy part. The mistakes are in what goes in around it. The most common one is skipping the flue liner. An insert has a much smaller outlet than the old open fireplace, and running it up an oversized masonry flue means poor draft, cold starts and, on gas, a real safety risk.

    The other misses are sizing and connections. An insert too big or too small for the firebox never runs right, and gas and electrical work done casually is how you get leaks and failed inspections. None of this shows on day one, which is why a cheap install can look fine and cause trouble later.

    We do the parts you cannot see properly. We size the insert to the firebox, run a correctly sized stainless liner up the chimney, and make the gas and electrical connections to code, then test that it drafts and runs safely before we call it done.

    • An insert vented into an unlined, oversized masonry flue
    • A unit too large or too small for the firebox
    • Gas connections made without proper testing
    • No insulation or seal around the installed unit
    • An install never checked for draft or safe operation

    A properly installed insert is clean, efficient and safe for decades. The liner and the connections are what make that true.

    How it works

    What an insert installation looks like

    From measuring up to the first fire, we handle the whole job and leave it ready to run.

    1. 1

      We measure and talk through options

      We measure the firebox and check the chimney, then walk you through gas versus wood and the sizes and styles that will fit, based on how you want to use it.

    2. 2

      You get the scope and the price first

      The unit, the liner, the connections and the finish, with the number, before anything is ordered. Nothing starts until you have said yes to it.

    3. 3

      We line the flue for the insert

      We run a correctly sized stainless liner up the chimney to match the insert, which is what gives it a clean draft and safe venting.

    4. 4

      We set the insert and make the connections

      The insert goes in sized to the opening, sealed and insulated, then the gas line or electrical is connected to code and the surround is finished off.

    5. 5

      We test it and show you how it runs

      We fire it up, check the draft and safe operation, and walk you through the controls so you can use it with confidence from day one.

    Questions

    Fireplace inserts, answered

    What is the difference between an insert and a fireplace?

    Your fireplace is the masonry opening in the wall. An insert is a sealed firebox that fits into that opening and turns it into an efficient heater. Instead of an open fire that loses most of its heat up the chimney, you get a controlled, glass-fronted fire that pushes heat into the room.

    Should I get a gas or a wood insert?

    It comes down to how you want to use it. A gas insert is instant, clean and controllable with no wood to handle, which suits most people who want easy warmth. A wood insert gives you a real wood fire that burns far more efficiently than an open hearth. We talk both through with you before you decide.

    Do I really need a new liner for an insert?

    In almost all cases, yes. An insert has a much smaller outlet than the open fireplace, so venting it up the big old masonry flue gives poor draft and, on gas, a safety risk. A correctly sized stainless liner is what makes the insert draft cleanly and run safely, and we include it in the install.

    Will an insert fit my existing fireplace?

    Most masonry fireplaces can take an insert, but the unit has to be sized to your firebox. That is why we measure first and then match a unit to the opening rather than the other way around. If your fireplace is an unusual size or shape, we will tell you what your options are.

    How much heat will an insert actually give?

    A lot more than an open fire. Because it is sealed and radiates rather than drawing room air up the chimney, a well-sized insert can genuinely heat the room it is in and take the edge off nearby spaces. We size it to the room so it heats well without being overpowering.

    Can you install a freestanding stove instead?

    Yes. If you would rather have a freestanding wood or gas stove than an insert set into the fireplace, we install those too, with the correct flue, hearth protection and connections. It is a different look with the same goal, efficient heat done safely.

    How much does insert installation cost?

    It depends on the unit you choose and the work around it, mainly the liner and the gas or electrical connections. The insert itself is the biggest variable. We measure, help you pick a unit that fits the budget, and give you the full number, install included, before anything is ordered.
