This is a must call company! Napa Valley Window Cleaners were earlier than they said which was great for me. Theses guy's worked their A's off and did a great job. I highly recommend them. I have a two story house and they were fast and professional and the quality of work was on point.

Russ and Juan came at the appointed time, and removed their shoes when indoors (we have white carpets). They cleaned our windows from inside and out plus screens. An hour plus later they were all finished with our two level home (4 windows plus sliding glass doors). They were clean and sparkling.

We have used this company for a number of years cleaning our windows. They do an excellent job. Highly recommend Solomon and his team. They charge a reasonable amount for the work they do. We recently had them clean our gutters - an excellent job! The team is always professional and get right to work. They always do a great job!
Napa Valley Window Cleaning did a great job on our house. Russell was very personable and went beyond his scope of work to include a few little things that he probably didn’t have to clean, but chose to anyway. The office staff did everything they could to accommodate us and get us in their schedule quickly. We will certainly be using them regularly to service our windows.
Had my windows and screens washed yesterday, also soft/power-washed carport and deck. Great experience. They did thorough work, on time and very courteous crew.
Solomon and his team are very professional. They are extremely polite and efficient. We haven’t had our windows washed in four years, and they look amazing! Our whole house looks brighter and cleaner because of the beautiful job they did. At the end of the cleaning, they followed up to make sure that they cleaned any missed spots. They also did a great job pressure washing our concrete. We would definitely use them again in the future.

The International Window Cleaning Association (IWCA) recommends having residential windows cleaned twice a year by a professional window cleaner to conform to the standards of the industry. Spring and fall are generally the seasons of choice for most homeowners, but with the mild winters in the Napa area it is a matter of personal preference.
We suggest that you wait until the builder completes the construction process before you have your windows cleaned. Additional tip: Don’t install screens until the construction is done. This will ensure that no mud or debris will permanently damage your screens before you even move into the home. Waiting to install the screens will also save you money by not having to pay a window cleaner to clean them.
We define a window pane as a piece of glass that has some sort of bordering material (wood, vinyl, metal, etc.). For example, a double hung window is 2 panes while a casement window is counted as 1 pane. Each pane has an inside and an outside and the price for each will be determined by whether or not the homeowner would like both the interior and exterior cleaned or just the exterior. French panes (or cut outs) are priced differently than standard windows.
Napa winters tend to be pretty mild, and we are a year-round window cleaning company. As long as temperatures don’t drop too far below freezing and the wind is not extreme we are cleaning windows and gutters.
Our free estimates are different because I am able to assess every aspect of the potential job. Giving a firm quote in person will avoid any billing surprises you might get with an over the phone estimate.
For window cleaning, the quote is initially based on the type of package you select and then tailored to reflect the number of window panes, the size of the windows, and how easy the windows are to access. Gutter cleaning quotes vary based upon whether the job is for routine leaf cleaning or involves the removal of more significant build-up (usually occurring over a number of years). Regardless, quotes are based on linear foot of gutter and then adjusted to take into account the number of downspouts and the height, pitch, and style of the roof. To a large extent, deck, patio, and driveway cleaning rates depend on the size of area to be cleaned.
No, unless I require access to clean the inside of your windows, to remove screens, or to get to a portion of your property that is otherwise inaccessible.
Rain usually does very little to spot up clean windows. That’s because it’s the dirt on the glass that causes the rain to spot and streak windows. However we know that sometimes a hard rain can impact up a good window cleaning, that’s why we offer a rain guarantee. If it rains within five days of having your windows cleaned by us we will come out at your request and touch up any areas that are spotted or streaked. Now you can relax and not worry about the forecast.
Clean windows and dirty screens are not a good combination. Screens trap dirt and debris, when it rains that dirt is then transferred to the clean window. We recommend that if you have screens, you get them cleaned with the windows.
Yes , Please have your shades or curtains open and any furniture or knickknacks removed from the window area. This will allow for the cleaning process to be smoother and avoid any broken items.
