Your merchandiser is the one refrigerator customers actually look at. When the glass sweats, the frames drip and a peeling gasket dangles in view, it does not just lose cold air; it loses sales. Nobody grabs a drink they cannot see.
The Gasketeers re-seal glass display doors on merchandisers, display cases and grab-and-go coolers across Boulder County, so doors close flush, glass stays clear and product stays cold out front where it earns.
Signs your display door seals are failing
- Fog or condensation on the glass that does not clear after the door is shut.
- Water beading on the frames or pooling in the track of sliding doors.
- Gasket visibly peeling, split or hanging at the corners, in full view of customers.
- Doors that bounce open or need a push to latch.
- Product on the top shelf running warmer than the rest of the case.
- The case running constantly and still sweating on humid days.
Sweating glass: gasket or heater?
Fogged glass has two usual causes: a leaking door seal letting room air reach cold glass, or a failed anti-sweat heater in the frame. They look the same from the shop floor but need different fixes. We diagnose which one you have and tell you straight. If it is the seal, we replace it on the spot. If it is the heater, you find out before spending money on the wrong part.
Swing doors and sliders, both covered
Swing-style merchandiser doors seal with magnetic gaskets much like a reach-in; sliding doors rely on wiper seals and track sweeps that wear even faster. We replace both, matched to the door maker’s profile, in food-safe materials that stay flexible. Odd-sized or discontinued display doors get custom-fabricated seals.
What a leaking case costs a storefront
A merchandiser exists to sell. Fog hides the product, drips stain the floor customers stand on, and warm top shelves quietly ruin stock you paid for. Add the energy a self-contained case burns running nonstop against a leak, and a seal that costs less than a shelf of spoiled product starts to look like the best margin decision of the month.

Frequently asked questions
Why is my glass door cooler sweating?
Either warm room air is leaking past a worn gasket and condensing on the cold glass, or the anti-sweat heater in the door frame has failed. We check both on site and quote the actual fix, not a guess.
Will a new gasket stop the fog?
If the seal is the cause, yes: with the leak closed, the glass stays near case temperature on the inside and room air stays out, so condensation stops. If the heater is the cause, a gasket alone will not fix it, and we will tell you so.
Can you re-seal sliding glass doors?
Yes. Sliders use wiper seals and bottom track sweeps rather than magnetic gaskets. They wear faster than swing-door seals and are just as replaceable.
How long does it take?
Most display door seals are replaced in minutes per door once we are on site, and we schedule around your trading hours so the case stays stocked and selling.
Do you service True GDM merchandisers?
Yes, GDM-series doors are one of the most common jobs we see, along with Beverage-Air and Turbo Air merchandisers. We match the OEM gasket profile for each.
