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."

"Martin and his crew completed ten very involved projects for us today. We are very pleased with the work as it was done in a very professional manner. Martin indicated they could complete the jobs in one day and they accomplished this. The jobs involved power washing, painting, repair of towel bar, grouting, fixing hinges on a door, repair of garage door frame and cleaning of spindles on the porch. We told Martin that we were very happy with the results and would call him in the future for other projects that might be needed. Richard Huckstadt 5/19/26."

"My overall experience with Health First Cleaning was very positive. I went with them because they had good reviews on Home advisor, and their price was competitive. I had air ducts and dryer vent cleaned. The two technicians who came were very knowledgeable and courteous. They wore the shoe covers at all times, and cleaned up after completing the job. No dust escaped their vacuum. They were very detailed, cleaned all the air duct covers, wiped clean any part that was dirty. They even offered some nice tips about my heater unit maintenance. For me, it was a care-free and pleasant experience. The two technicians were very organized, working non-stop, thru lunch time until they completed the whole operation. I live at Guard Hill Manor and I would call them again in the future when I need another air duct clean."

Window Cleaning FAQs, answered by experts

Professional house cleaners may use a variety of cleaning products, but a great option is a cleaning solution containing ammonia or white vinegar, water, and several tablespoons of dishwashing liquid.

Yes, in most cases, you can add a few drops of Dawn to a spray bottle full of vinegar to remove hard water stains. This solution can be used on your dishes, or you can use it in your shower, bathtub, or sink to get rid of hard minerals. Simply combine the ingredients, shake them up, then spray the solution onto limescale-ridden surfaces. Wait around an hour and then scrub the surface down.

It depends on the surface you’re trying to clean. For example, a mixture of vinegar and water is a good option for a deep cleaning, including removing hard water stains from glass or stainless steel. However, vinegar is too acidic for granite and other types of natural stone, so it’s better to use a combination of baking soda and water on those surfaces.

A standard professional cleaning of an entire apartment typically takes 2 to 3 hours. However, the timing varies depending on the size of the apartment, the number of people and pets that live in it, and how frequently it is cleaned. A deep cleaning typically takes 4 to 6 hours.

You should avoid using abrasive materials and harsh chemicals when cleaning windows. Abrasive tools like scrubbing pads, rough cloths, or steel wool can permanently scratch and damage the glass. Harsh chemical cleaners containing alcohol or ammonia can damage window treatments, frame materials, and special features like tinting. It is also best to use distilled or filtered water instead of hard water, which can leave spots or streaks. For best results, use a clean microfiber cloth to wash the glass and old black and white newspapers to dry it without leaving streaks.
