What is insulated glass replacement?

An insulated glass unit is two panes of glass sealed together at the edge. When the seal fails, the glass fogs. We replace the unit and keep your existing frame.

Why is my double-pane window foggy?

Moisture has gotten between the panes because the edge seal has failed. It cannot be wiped away from inside or outside, and the unit generally needs to be replaced.

Do you replace the whole window?

No. We replace the glass unit only. Frame repair and full window replacement are not part of this service, and we will tell you if the frame is the real problem.

How much does insulated glass replacement cost?

The price depends on the size of each unit, the glass type, and how many units you have. We measure and quote from your actual windows.

Can you replace insulated glass in storefront windows?

Yes, in existing aluminum framing. We measure the unit, order a match, and install it.

Yes. We serve Baltimore, Towson, Owings Mills, Cockeysville, Dundalk, and Annapolis, and nearby areas. Call (443) 443-5585 to check your address.

How do I get started?

Call (443) 443-5585 or send the quote form with a photo of the foggy glass. We schedule a time to measure and quote from the actual units.

Replace the Glass, Keep the Window

An insulated glass unit, or IGU, is two panes of glass separated by a spacer and sealed at the edge. When the seal fails, moisture gets between the panes and the glass fogs.

The frame is often fine, so replacing only the unit can cost less than replacing the window. We measure the unit, order a replacement to match, and install it in your existing frame.

I purchased my glass from Baltimore Glass company my glass came back in about four days. I was absolutely pleased with the results, not to mention the wonderful customer service by Mrs.Rachell who made my purchase a wonderful experience. I highly recommend this company for all your glass needs.

My 2 techs were absolutely amazing! They even found an error before installing the heavy 70+ pound shower door that the plumbing company/3rd party "TBA" didn't install a king stud! Great work for sure!

I have used the services of Baltimore glass three times and every time has been a fantastic experience. Their work is excellent, service is fast and everyone is so friendly. Big thumbs up!

Had a fantastic and professional experience with Baltimore Glass. The gentleman were polite and efficient. The customer service representative, Rachel was great too. She explained the prices, collected the deposit and called before completing the final invoice. Highly recommend!
