Custom Fireplace Doors Made to Measure in Lakewood, CO
Glass doors built to your actual opening, with glass and framing matched to the type of fireplace they sit on.
A door set keeps sparks and embers in the firebox, cuts the warm room air that drifts up an open flue once the fire is out, and gives a plain opening a finished edge. Every job starts with measurements, because a masonry opening and a prefabricated unit need different frames.

What a door set does
- Holds sparks and popping embers inside the firebox
- Slows the heated room air that escapes up the flue between fires
- Frame measured to your opening, not pulled off a stock size chart
- Tempered or ceramic glass chosen to suit the fireplace type
A door set is a frame, glass and a seal
Custom fireplace doors are a steel or alloy frame, hinged or bi-fold glass panels, and the seals and anchors that hold the whole assembly tight to the opening.
The frame overlaps the face of the fireplace or fits inside the opening, depending on how the fireplace is built. Behind the glass, most wood-burning sets also carry a mesh screen so the fire can be enjoyed with the glass swung open. Hardware, hinges and the gasket around the glass are all part of what makes a door seal and close properly for years.
Here is the part homeowners rarely hear: fireplace openings are almost never square. Masonry fronts settle, brick courses run out of plumb, and old mortar leaves an uneven face. A stock door ordered to the nearest inch leaves gaps at the top or one side, which is exactly where drafts and smoke smell come through.
That is why we measure the opening in several places, check how flat the face is, and confirm whether the fireplace is masonry or a prefabricated metal unit before any door is specified. The fireplace type drives the glass, the frame style and the way the doors are anchored.
Open fireplace fronts are still common across Lakewood
Plenty of homes around our W Cedar Dr shop still have a wide open firebox with nothing across the front but a hearth and a screen.
An open front looks fine while a fire is burning. The problem shows up the rest of the time. With the damper worn or left open, heated air from the room keeps moving up the flue, and cold air drops back down into the room when the house is quiet.
Colorado winters make that easy to feel. A cold, dry night with wind off the foothills turns an open firebox into a steady draft on the floor near the hearth. A fitted door set closes that path when the fireplace is not in use, and a working damper behind it does the rest.
Doors also solve the other half of the problem: seasoned wood pops, and an open front lets embers land on carpet or flooring. Glass doors with a mesh screen behind them keep that inside the firebox where it belongs.

What worn doors are telling you
Each part of a door set has a job. When one of them gives out, it usually shows up as one of these.
Glass is cracked, chipped or clouded Glass panel
Cracked or permanently hazed glass often means the panel was run hotter than it was rated for, or the wrong glass type was fitted in the first place. We replace the panel with glass suited to the fireplace, and look at the firebox while we are there to see why it overheated.
See a level 1 inspectionDoors will not latch or sit flush to the opening Frame and anchors
A door that rocks or leaves a gap is usually anchored into soft mortar or a face that is no longer flat. Firming up the masonry at the opening comes first, then the frame has something solid to pull against.
See mortar repointingCold air still pours in with the doors shut Damper and flue
Doors reduce airflow through the opening, but they are not a seal on the flue itself. If the draft continues, the damper above is usually warped, rusted or stuck part open and needs attention.
See damper repairSmoky smell in the room when the fireplace is cold Flue and creosote
Closed doors cut the odor, but the source is deposits inside the flue giving off smell as air moves down the chimney. Cleaning the buildup out addresses the cause rather than covering it.
See creosote removalCan I burn a fire with the glass closed?
That depends entirely on the doors and the fireplace, and the manufacturer's instructions are the answer.
Many door sets for open wood-burning fireplaces are meant to be fully open while a fire is actively burning, with the mesh screen pulled across. The glass then gets closed once the fire has burned down, to stop room air from running up the flue overnight. Other doors, including those built for certain inserts and gas appliances, are designed to stay closed. Mixing those two up is how glass gets overheated.
Glass type follows the same logic. Tempered glass is common on doors for open masonry fireplaces, where the panels are not meant to face sustained direct heat. Ceramic glass tolerates much higher sustained temperatures and is used where a closed-door burn is part of how the appliance works. Fitting tempered glass where ceramic belongs is a failure waiting to happen.
We tell you in plain terms how your specific doors are meant to be used, and leave the manufacturer's instructions with you.
Our standards for every door installation
Measuring, glass selection and fitting follow the same process whether the job is one replacement panel or a full custom set.
- Fireplace type confirmed first Masonry or prefabricated, because the two take different doors.
- Opening measured in several places Height, width and face flatness, not a single quick measurement.
- Glass matched to the appliance Tempered or ceramic, chosen for how the fireplace is actually used.
- Frame anchored into sound masonry Crumbling joints at the opening get addressed before fitting.
- Hinges, latches and mesh checked under load Doors should swing, latch and hold without rocking.
- Required clearances respected Doors fitted per manufacturer instructions and code requirements for the unit.
- Old doors removed and hauled off Broken glass and worn frames leave with us.
- Clean site throughout Removal and drilling create dust and debris, and we contain it.
How a custom door job runs start to finish
Three phases, in the same order, on every set we fit.
-
1
Measure and specify
We confirm whether the fireplace is masonry or a prefabricated metal unit, then measure the opening at multiple points and check how flat and plumb the face is. We look at how you use the fireplace, wood or gas, open burn or closed, and that decides the glass type, the frame style and whether the doors overlap the face or sit inside the opening. Finish options are discussed at this visit.

2
Fit the doors
Old doors come out first, including any broken glass and leftover anchors. Loose mortar or damaged brick at the opening is dealt with so the frame has solid material to anchor into. The frame is set level, anchored per the manufacturer's instructions, and the glass panels and mesh are hung and adjusted so they close evenly along the whole frame.

Check and hand over
We open and close every panel, test the latches and screen, and check the fit around the frame for gaps. Then we walk you through how these particular doors are meant to be used during a fire, how to clean the glass without scratching it, and what to watch for as the seasons go by.

Frequently asked questions
Door questions we answer most often on the phone.
How much do custom fireplace doors cost in Lakewood?
It depends on the size of the opening, the frame style and finish, and the glass the fireplace requires. Call 720-608-7668 and we will measure on site and quote the specific set your fireplace needs.
Will glass doors really keep heat in the house?
Their biggest saving comes after the fire is out. An open firebox lets heated room air keep drifting up the flue for hours while the coals die down. Closing fitted doors cuts that flow sharply. They also block the cold draft that drops back down the chimney on still winter nights. For the full benefit, the damper above needs to close properly too.
What styles and finishes can I choose from?
In general terms, doors come as hinged pairs, bi-fold panels or single-panel designs, with frames that either overlap the face of the fireplace or fit inside the opening. Finishes range from matte black and dark bronze tones to brushed and polished metal looks, with options for how wide the frame reads and how the handles are shaped. We show you the choices that fit your opening and your fireplace type rather than a catalogue of sets that will not work.
Can I keep the doors closed while a fire is burning?
Only if the doors and the fireplace are built for it. Many sets on open wood-burning fireplaces are meant to be open during the burn, with the mesh screen across, and closed once the fire has burned down. Others, including doors on certain inserts and gas appliances, are designed to stay closed. We tell you which applies to your installation and leave the manufacturer's instructions with you.
My glass is cracked. Can you replace just the panel?
Often yes, if the frame and hinges are still sound and the right glass can be cut to fit. We measure the panel, check the gasket and clips that hold it, and fit glass suited to the fireplace. Where the frame is warped, rusted through or the hardware no longer holds, replacing the whole set is the better repair, and we will say so.
Do prefabricated fireplaces take the same doors as masonry ones?
No. A prefabricated metal fireplace is a listed appliance, and doors for it have to be compatible with that unit and fitted the way its instructions require. Masonry openings allow more flexibility in frame style and mounting. That is why we identify the fireplace type before anything is measured or ordered.
