Vinyl Windows Replacement - When and how?

When it comes to the replacement of windows in a house or apartment, we know that it is an undertaking that requires careful consideration, with several issues to think about. Although the currently available vinyl windows are a modern and practical solution and replacing old windows with new ones is often a necessity, the choice of type, brand, or style is important, as is the decision on the method of installation. So, when it comes to vinyl window replacement work, where do you start?

Preparing for a vinyl window replacement is a critical part of your window replacement process. With weather a consideration, it is preferable to do your vinyl window replacement work  in spring, summer and autumn, as this will ensure that the installation is more efficiently done than it would be in winter, and the low temperatures outside mean winter work could make your room too chilly.

When it comes to vinyl windows replacement, precise measurements of the window openings should always be made, with some clearance between the opening and the window frame always needed. This ‘expansion gap’  prevents the profiles from deforming during their use, allowing for a tight connection of the window with the wall using anchors and sealing foam, a benefit of vinyl windows replacement work.

One of the critically important early stages of a vinyl windows replacement job is the removal of old windows and the cleaning and alignment of openings, a process that includes removing all fragments that are not part of the building walls, i.e. plaster, mortar and caulking. For vinyl windows replacement where cavities  are found left in the walls after disassembly, it is necessary to prime and fill them with mortar.

During any vinyl windows replacement project you should remember that the frames should never be in contact with the wall, so that no forces from the walls are transferred to them. This means that any vinyl windows replacement products must always be smaller than the opening. With our vinyl replacement windows, the frames are fixed to the wall with anchors or dowels, and the whole thing is sealed with special foam, which insulates well, cushions and compensates for differences in tension.


Is it possible to repair vinyl windows?

Any type of windows repair Chicago residents rely on depends on the type of damage to the window. Glass in windows may be replaced by filing a claim on your window warranty or by contacting a glass specialist for professional window glass replacement. Screens and hardware on windows can also typically be repaired or replaced. It is unlikely for the window frame itself to break but if it warps or cracks, it cannot be repaired, it is necessary to replace the entire window unit.

Do vinyl windows require much maintenance?

One of the largest advantages of a vinyl window is that they require very little maintenance.  You basically need to simply clean the window a few times a year to remove buildup from leaves, bugs, or dust.  The material used does not require application of paint or sealant.  Yet, it is significantly more complicated to stain or paint a color other than the original one from the manufacturer when compared to wood.

Is it possible to obtain vinyl windows colors other than white?

Absolutely. Vinyl windows are available in colors other than white. They have become increasingly popular during the past few decades and now you can encounter them in basically any color if you investigate the appropriate manufacturers. Always remember that the darker the color of a vinyl window frame, the more likely it will absorb heat as time passes. This heat can cause faster warping and could also cause the colors to fade over time, requiring window replacement Chicago property owners prefer.
