A film or haze on the glass
Normal on a sealed gas unit over a season, and worth removing properly rather than with household glass cleaner.

Fireplace cleaning covers what you can see and touch: the firebox, the surround, the glass, the log set or media bed. On a wood unit that means soot and ash. On a gas unit it means the dust and residue that dull the glass and take the look out of the flame.
Both are worth doing before the season rather than during it, and on a sealed gas unit the clean is also the moment we check the gasket, which is the part of that appliance most often overlooked.
Chimney sweeping deals with the vertical part. Fireplace cleaning deals with the part you sit in front of: the firebox surfaces, the grate, the damper, the glass on a gas or sealed unit, and the smoke chamber immediately above the opening.
It is the work that makes the fireplace usable and presentable again, and on a sealed gas unit it is also the only time anyone looks closely at the gasket and the glass seat.

Ash left sitting in a firebox holds moisture, and the salts in it are corrosive to metal components and hard on refractory surfaces over a season.
On a gas unit, film on the inside of the glass and dust across the burner both change how the appliance runs. Clean glass is also the only way anyone can see the flame pattern, which is the clearest indicator that the unit is burning correctly.

Holds moisture against metal and masonry. Easy to clear and easy to leave for years.
Usually residue in the firebox rather than anything in the flue.
Smoke escaping at the top of the opening, which is worth understanding as well as cleaning.
Debris and corrosion in the pivot. It is checked and freed as part of the same visit.
Ash, soot and residue cleared from the floor, walls and surround.
Gas fireplace glass cleaned properly rather than smeared, and the gasket checked while it is out.
Logs lifted, media beds cleared and everything reset to the manufacturer position.
Stone, brick and tile cleaned down without taking the finish with it.
Drop cloths and HEPA vacuum so nothing travels into the room.
Drop cloths, a sealed opening and HEPA vacuum containment, the same as a sweep. Soot travels further than people expect.
Ash and debris removed, the grate lifted and cleaned, the floor and walls of the box brought back.
On a sealed unit, with products intended for it, and the gasket is checked for compression while the glass is out.
The ledge above the opening collects the heaviest debris and the damper is tested through its full travel.
A cracked panel or a hardened gasket is visible during this work and you will be told about it.
Shorter than a full sweep, usually an hour or two depending on the unit and how long it has been.
The room is protected throughout and the fireplace is left ready to use rather than ready to clean up after.
Let ash cool completely before removing it, and leave a thin layer in a wood firebox during the season if you use it regularly. It insulates the base.
On a sealed gas unit, do not take the glass off to clean it yourself. The gasket and the seating are part of a sealed system and refitting it incorrectly is a safety issue rather than a cosmetic one.
Straight answers from the work we do here, not general advice copied from a manual.
Yes. It needs the right product and method. We also check the gasket while the glass is out, which is the part most often missed.
Most fireplace cleans run under an hour. Heavy buildup or a large surround adds time, and we tell you before we start if it looks like more.
No. A sweep deals with the flue above. Fireplace cleaning deals with the firebox, grate, damper and glass. Some homes need both, and we will tell you which applies.
We would rather you did not. The glass is part of a sealed system and refitting it disturbs the gasket, which is what makes it sealed. It is a safety item rather than a cosmetic one.
Once a year for a fireplace in regular use, usually before the season. If you burn most weekends through winter, the ash clears more often than that, but the full clean is an annual job.
The hearth and the immediate surround, yes, as part of leaving the area as we found it. Restoration of stonework or a damaged surround is a different job and we would tell you if that is what it needs.
It leaves with us. It goes into sealed containment rather than your bin, which is also why the HEPA vacuum runs for the whole visit.
Full flue, smoke chamber and firebox swept with HEPA containment throughout.
