The deterioration of the seal may also be caused by environmental factors like exposure to direct sunlight or making use of powerful chemical cleaning products that may harm the glass and weaken the seal.

It is crucial to measure the window accurately before replacing it with a double-glazed sealed unit. The UPVC frames that they sit in are very rigid and if the unit is too large it won't fit. To do this precisely, it is necessary to remove the beads and take a careful measurement. This will ensure the new sealed unit has the correct size. You can purchase replacement UPVC frames beads on the internet. Suppliers provide a range of warm edge options such as steel or aluminium.

The next step is to carefully cut the adhesive sealing strip that keeps the glass in place with the knife of a utility. Once the adhesive strip is removed then use a putty or shovel to gently pull the frame off of the glass. Be aware that glass is brittle and can break if you push it. Be careful not scratch or cause damage to the sealant or frame.

Clean

After taking the old unit off, the frame can then be cleaned and prepared for a replacement double-glazed window that is sealed. Depending on the design of the window, it may require to be primed or painted prior to when the sealant is applied. It's important that any varnish or paint is allowed to completely dry before the sealant is applied.
If the window in question was secured with beads then they will need to be removed before a new unit can be installed. This can be done with a screwdriver or a sharp chisel. The blade should be placed on the edge of the bead, and gently remove it from the frame. To avoid damaging the window frame, make several smaller cuts instead of a deep cut. After you have removed the bead frame, gently lift it off of the glass and put it away.
With a knife or tool, cut off any remaining sealant off of the bottom of the glass. This will ensure a solid seal when the panes are re-sealed. After the glass has been cleaned clean, you should wash it on both sides to get rid of any residues.

Accurate measurements are the key to an ideal fit. A UPVC window frame has little tolerance and if you buy a new double-glazed unit that is just a few millimeters too large, it won't seal properly. To avoid this issue make sure you measure the width and height of the old window, and relay these dimensions to your window manufacturer.
A double-glazed unit's seal can break down for a number of reasons, but the most common is the result of condensation between two panes of glass. This can cause visible calcium deposit on the glass. This is a sign of an issue with the gas filler in the sealed unit or moisture that has gotten into the frame.
