They were on time, and friendly. The team of three cleaned our windows with very little disruption to me. I was impressed with how they cleaned my 22 foot high windows and my cathedral. Highly recommend them!

Exterior home staging with GEM Home Maintenance

What's the number one home improvement to invest in when selling your home? Clean windows! According to “MONEY” magazine, professional window cleaning yields the #1 return on investment for all pre-sale home improvements! An investment with a 768% return is a must-do!

Home staging has become a must in selling homes, giving potential buyers a better visual idea of your home's potential. But, there is one problem: 75% of homeowners make a decision BEFORE they even enter the house! Does the exterior curb appeal of your home showcase how great it is? The only way to make a great first impression is to ensure that the outside of your home invites them inside!

Realtor Magazine Online states that the fourth thing a seller must do before putting their home on the market is to clean the windows and window coverings.
