Yes. We have a contractors license, surety bond and general liability insurance.

Our technicians are employees who drive company vehicles and work with company tools. This offers much more protection for homeowners than the subcontractor model.

No. Most people are at work during the day while we perform our services. We can usually handle all the details over the phone when we set the appointment.

We take a visa or master card over the phone at the time we make the appointment. No action is taken on the card until the next business day after the work is completed.

First of all, we are very safe and it is unlikely that anyone will get hurt at your residence. AA Window and Gutter Cleaning is licensed with the Department of Labor and Industries and this agency provides protection for employees that are injured on the job and pays for their medical bills as well as time loss. This State sponsored program protects the employee, the employer and the homeowner.

It is a personal decision, but clean windows let light in the house and can help chase away the blues. We think a great schedule is to clean outside windows once a quarter and inside whenever they start to look like they need it.

We have several methods depending on how far the roofing overhangs the gutters and the type of debris in the gutters. One method we use is a gutter tool that attaches to the end of a pole so we can pull the debris to us and remove it by hand. Another method we use is a blower to clear debris out of the gutters. We are careful to prevent debris from going into your downspouts and drains. We will clean up the mess.

Many people spend a lot of money on gutter protection systems hoping to eliminate the need to clean their gutters ever again. We have found that the best products help reduce maintenance at most. All gutter protection products require some level of maintenance as leaves, needles and other debris gets lodged in them over time. Watch out for the claim that you’ll never need to clean your gutters again, because you’ll still need to keep the gutter protection system clean.

If there is an area that is under heavy tree cover that perpetually drops (i.e. cedar) then a rigid metal screen can be helpful. We have these types of screens available and one product we like is from http://www.e-zgutter.com/.

Most homes are better served by a routine maintenance schedule. If your gutters are getting clogged regularly then there is probably debris landing on your roof also. AA Window and Gutter Cleaning can put you on our recurring maintenance schedule and take better care of your roof and gutters for a modest fee and you can avoid the up front investment of thousands of dollars.

No, we advise our clients against pressure washing roofs. Pressure washing often damages roofs and reduces the life of the roof because it washes off a layer of the roof.


We have pressure washers and use them for cleaning concrete and rinsing siding and decks.

We blow the loose debris from the roof with commercial grade backpack blowers. If there are clumps of moss more than half an inch above the shingle then we use a brush to agitate the moss, and then use the blower again.


Next, we clear all the debris from the gutters and downspouts.


The last step is to treat the roof with zinc sulfate to kill any remaining moss. It takes about one month for the moss to change color and die. We guarantee that all the moss will change color and die or we will come back and apply more zinc sulfate. The wind and rain generally weather away a significant portion of the remaining dead moss. This process is widely accepted by our 10,000+ customers. Many realtors arrange for us to prepare their clients homes before sale or to satisfy an inspector’s request using this same process.

Gutters need to be cleaned regularly in order to prevent the debris from blocking the flow of water. Clogged gutters are often the cause of water damage that can run up high repair bills or remain unnoticed until an inspector finds the damage and adds a complication to the sale of your home.

Yes. Starlings are notorious for getting through the screen that your builder installed to keep birds out of your vent holes. We cut one quarter inch galvanized steel mesh into strips and staple it to the outside of your vent holes. We have never had any birds able to get through this heavier material.

Some roofing materials are more fragile than others and we are very familiar with the different types of material and proper methods for walking on them. The real answer to this is that allowing debris and moss to accumulate on your roof does much more damage than carefully walking on the roof to maintain it. We will certainly access your roof and determine if it is able to sustain our walking on it.

We start out by hiring people with a natural talent toward working on uneven surfaces and with a high level of agility.


We hired GRAVITEC to supply and train our technicians in the use of fall protection equipment (ropes and harnesses). In addition, we use high quality ladders with leg levelers and stabilizer bars and Korkers® brand safety sandals for traction on slippery roofs.


We train our people to think creatively and look for the safest way to accomplish a job. We allow our technicians to walk away from work if they cannot figure out a safe way to get the work done.

When we rinse the siding on a house with a pressure washer we use an extended wand with a wide angle nozzle (40 degrees) and we hold the wand back from the house a substantial distance (12 – 24 inches). If there is algae and mildew on the siding we may apply 30 Seconds® (bleach & TSP) to the siding and let it sit for a few minutes before we rinse it off.


This process is as gentle as possible and still able to get the dirt and grime off your siding. The older the paint the more likely there will be some areas that lose a bit of paint. We monitor this and will seek your guidance as to whether we try to completely avoid any paint coming off, or if you are planning on touching up the paint and want us to get the surface as clean as possible.
