Customers say: Quick response

"Kevin and his crew showed up up for us on a very last minute request. He was very helpful and willing to make it work when we were under a time crunch. We had called several companies hoping to get someone out, and he was one of the few who was willing to come out and actually perform the work, rather than just come for an estimate only.  Furthermore, he was prompt in returning our initial phone call, and called us again before he planned to arrive at the house.
The crew was quick, efficient and I believe we were given a very fair price for the amount of windows- cleaned inside and out on a three story home. 
Thanks to Kevin and his crew for making it work for us.
A company who caters to their clients is a real bonus these days, when so often it is the other way around.

"Fernando and his team did a complete gut renovation of a full bathroom in my East Rock Victorian in 2021. I cannot speak highly enough of his professionalism and the quality of work. He coached me through picking out tile, vanity, lighting and fixtures and I was thrilled with the final result. His crew cleaned up every night - above and beyond what any other contractor would do. Months later, water leaked from an old bathroom upstairs to the new bathroom below and Fernando showed up immediately to inspect and repair."

"Luckily, they had to come back because they left a ladder at my house. Martin Duran, I think the owner was great and professional on the phone. There were many touch-ups and areas that needed to be fixed and he assured me his guys would do it. It was all finished very well. This was my first time using a window cleaner, so I now know to look at each window carefully, especially the sills and tracks which many weren't cleaned. I do plan on using them again because of the owners responsiveness for customer satisfaction."

"From beginning to end, my experience with Health First Cleaning was seamless. Marlen, the owner, came to my home to do an assessment and describe the process to me. Once the crew came, they were meticulous and did an amazing job. Marlen returned before the end of the day to ensure the job was to my satisfaction--which it was! Additionally, Marlen was incredibly responsive over text and email throughout the process. I'm so happy I found and chose Health First"

Window Cleaning FAQs, answered by experts

Use of harnesses and ladders ensures safe roof access.

Costs depend on window count, height, accessibility, labor, and whether interior and exterior cleaning is required.

Unless it’s written into the purchase agreement, there’s no legal obligation that a house you’ve bought has to be clean before you move in. The previous owner is generally required to sweep the house, but that doesn’t guarantee everything will be spotless upon your arrival. If possible, discuss the cleaning requirements with the real estate company before moving in.

There are a few qualifying questions you can ask a professional window cleaner to help you decide if it’s the right company for you:

  • Does your price include the inside and outside of the windows?

  • Will you clean the tracks, rails, and other internal components?

  • Are you fully insured?

  • How many years of experience do you have?

  • What kind of cleaning products do you use?

  • Do you have any customer references?

  • Do you provide any other services, like exterior power washing?

The best thing to clean windows with is a mixture of white vinegar, warm water, and dish soap. This will remove dirt, pollen, and grime without destroying any tints or protective films on your glass. You can also use a commercial window cleaner, but make sure to choose one that doesn’t have ammonia in it, as this can damage window coverings and frame materials over time.
