I originally called for window cleaning, as I am preparing to sell my home. Ended up with sparkling windows, a washed home, a clean deck, roof, gutters and the concrete walkways, patio and driveway. The team was amazing and did an excellent job I’m a bit giddy over the work. Thank you.

Waste, Junk, Building Materials and Debris - Remove and Haul - For Business
Fast & efficient. Hauled away our stuff for recycling the same day we contacted them. Crew was very clean, and even picked up the items from inside of our house by themselves.

Window Cleaning
Preferred Janitorial Services provided us with an exceptional result when we engaged them to do our pre-sale home cleaning. This included washing the outside of the house, interior and exterior windows, skylight, deep cleaning appliances, floors, and more. We were under a tight timeline with our listing plans and Preferred Janitorial Services was willing to come and give an estimate during this busy time of year, as well as fit us into their schedule for the job itself. While this type of cleaning is an investment cost-wise, we feel the value we received from Preferred Janitorial Services was well worth it. I was on-site during the service and appreciated the hard-working team as well as the oversight of the job by the owner. The commitment to providing great results was evident. We would not hesitate to use their services again.

They beat all of the competition's prices right off the bat. Showed me they know their market and are willing to be the best price out there.

Dave and his team provided clear and professional communication from initial quote to finish (move-out clean). The day of the clean, we started with a walk through to further clarify my cleaning needs/wants to the cleaning team (4 hardworking cleaners!). My house had a lot of carpeted areas, and I was very pleased they also offered carpet shampooing/cleaning (not just vacuuming). I highly recommend this company, the quality of work was excellent, and the house looked & smelled amazing afterwards!!

I hired them for moving the large frames of furniture to an upstairs apartment, as well as junking furniture. They only took exactly what junk I requested, without confusion, but they were a bit hasty with the furniture. One of my antiques was chipped and all of the other furniture took a beating as well. I have sturdy, worn-out furniture already, so I didnt make a big fuss, but they were careful with the antique after I asked them it was special. They worked fast, they were very sweet, and the price was really good for what they got done. The team communicated well both together and with me. I'm pretty satisfied!
