I have used 1st State Window cleaning for several years, and. I have never been disappointed! I have been gradually replacing my windows, but 1st State even makes my old windows look like new! Steve and his crew are very accommodating and flexible and willing to work around my schedule.  This is one of the best services I have used in my home.  Great employees, too-friendly, respectful and. hardworking! Always pleased with the final result!-

Caroline from Chadds Ford, PA

They were great to work with. Very professional and efficient! The windows were spotless and all the items that needed to be put back in place were carefully done. Highly recommend this company!

Robert from Wilmington, DE

1st State is the first professional window cleaning company we’ve used. We chose them after reading quite a few of their reviews. They definitely lived up to the recommendations from the others who have used their service. The Window Cleaning Technicians did an outstanding job and the cost of the service was very reasonable.  I was emailed a reminder of the date and time the service was scheduled, the team called when they were on their way and arrived on time and finished within the estimate given. That, in itself, showed us that they are a professional and reputable company. There’s no going back to ‘do-it-yourself’ for us.  We will be using their service again.

Pat from Galena, MD

This is the second time we’ve used 1st State for our windows. We have an historic home with many windows. Each time they did an excellent job and were very easy to work with.

Cynthia from Middletown, DE

They did a great job! They moved the objects they needed to move to get to the windows and put them back when the work was completed. The windows are beautiful again. Customer service was great. They kept me informed of the process. I would definitely use them again!

1st state window cleaning-wow!

A pleasure to have a company give you an arrival time and actually be there on that time.

The window cleaning technicians were professional and thorough.

Karen from Wilmington, DE

Great value for the spend.  My windows have never been so clean.  Highly recommend!

Kathleen from Hockessin, DE

This was my first experience with 1st State. Appreciated getting a reminder email the day before. Courteous, face-masked (per Covid safety practice) two-man crew arrived on time (actually called to check if they could come a little earlier), did a fast  and thorough job.  They took the time afterward for me to walk around and confirm that I was happy with the work.  Will keep 1st State as my first choice for next window cleaning.

George from Middletown, DE

If you have been cleaning your own windows, this is an option you should consider.  1st State does a great job carefully cleaning your windows.  They call the week before, the day before and the morning of the cleaning.  Techs are polite and have all the right tools.  Everything in the way moved and put back in place.  Reasonably prices for the quality of service provided.  This is my second cleaning and I will have them back after the summer.

Janice from Kennett Sq, PA

I have used them for years and have never been disappointed. They are prompt and thorough communicators. The staff is efficient, friendly, and mindful.

Wendy from Landenberg, PA

I’ve used 1st State Window for annual window cleaning for several years and they’ve consistently provided high quality, good value service. The crew is professional, responsive, efficient and courteous. I highly recommend!
