Exterior Cleaning Roof & Siding, Johnson, Iowa

Amazing! I had the roof, siding and soffit cleaned on my 14 year old home. I can’t believe the difference it made! It looks new again! Sullivan was great to work with. There was absolutely no trace they had been there, other than the clean house and roof! I am very pleased. I will refer my friends and family to Sullivan Roof Cleaning!

Siding and Deck Cleaning, Johnson, Iowa

I found Bruce and Maria via their Your Tube video demonstrating their approach to cleaning the “green” stuff growing on the north and east sides of my home. I recommend watching it, it’s exactly who they are and what they do.

My house, deck and patio look brand new! I wish I had taken before pictures. The improvement is dramatic.

They arrived as scheduled, worked efficiently and with respect for my property. The work was completed for exactly the bid they provided when they visited my home to provide a free quote. I wish all contractors were so reliable and transparent. I am a very satisfied customer.

Bruce has done several roof cleanings for me and the results always exceed my expectations. He’s saved me thousands of dollars on my investment properties by making old roofs look brand new. He cleaned my gutters and siding in just a few minutes in what would have taken me hours with a power washer. With just a simple rinse, his cleaning solution removed dirt and grime that a pressure washer couldn’t remove. He’s got an amazing product.

Roof Cleaning-Pleasant Hill, Iowa

I was skeptical of this when my wife suggested it. I told her roofs were suppose to do this after time. I went to Menards to purchase a product and tried it in a small area ( no results) we went ahead and had it done and our roof looks like the day we had it installed. This is the best money we have spent to keep the house looking like the day we built it. GREAT JOB!!! I would recommend this to anyone.

You did an awesome job on my daughter’s log home, deck, railing, swing and chairs on the deck. They are totally impressed. My roof looks great, as well as, the stucco on front of my house. I appreciated your professionalism regarding communication and being where you said you would be at the time agreed upon.
