Why Replace Your Windows?

Replacing your windows is an investment that pays off. You don’t just get better comfort, you save money on energy, and it has long-term value that adds an aesthetic appeal to your home. Unsure whether it’s time to upgrade?

Here are the signs you might need a window replacement:

 

Rising Home Energy Bills

Older windows can let warm or cool air escape through cracks, forcing your heating and cooling system to work harder.

Uncomfortable Rooms

Window drafts can indicate poor insulation or thermal performance, making it harder to keep your home comfortable year-round.

Manage Noise Control

Aging windows often have failed seals, gaps or degrading frames that offer minimal sound buffering

Window Operation is Faulty

Difficulty opening or closing windows, sticking parts or pesky operational issues can be a sign that your window is nearing the end of its lifespan.

Cosmetic Issues are More Apparent

Chipped paint, tarnished hardware or material stripping can show a window’s age and outdate your home.

Less security

As an opening to your home, broken windows should be addressed immediately for your safety.

  • Specialty shapes replacement windows for unique, personalized designs.

Each style comes with custom sizing options, multiple hardware finishes and a variety of glass packages to optimize efficiency in any climate.

Material Options

A key decision in window replacement is choosing the right frame material. The most important part of choosing any window or door is understanding which type of material will work best for your home. Mountain West Window and Doors has a variety of Marvin window frames available in fiberglass, aluminum and wood.

While replacement windows made from vinyl are less costly, low-maintenance and can be decent insulators, they tend to soften or sag from heat or direct sunlight and have few color selections. That means when the temperatures get high, vinyl windows begin to have problems fitting into their openings, making them difficult to close and compromising seals.

Fiberglass replacement windows, on the other hand, have stronger structural performance, providing great insulation and premium durability. The fiberglass’s dimensional stability is very similar to window glass, making it an excellent choice for the intense climate of Arizona and Utah. Get better energy efficiency and a longer window lifespan by getting custom replacement windows from Mountain West Windows and Doors.
