One of the most important steps in preparing your house for sale is exterior cleaning. Roofs, gutters, siding, windows, exterior trim, decks and hardscape such as patios and driveways all need to be free of debris and dirt so your house appears to be well-cared for and in good condition.

Get a professional.  Although pressure washing machines are available for purchase or rent, consulting a professional (found under “pressure” in your local yellow pages) may be your best bet, especially if you plan to put your house on the market. “Soft washing,” unlike high-pressure cleaning, uses chemicals such as chlorine to remove debris and grime, so offers little or no risk of inadvertently causing damage. Professional cleaning of paved surfaces generally outperforms do-it-yourself, as hot water is used. A professional exterior cleaning service can sweep your roof and clean your gutters as part of the job, and some provide spot painting (after pressure washing) for areas that need touchup.

Get it done before you go on the market.  Exterior cleaning can be contracted on a monthly or quarterly basis, so that your house sparkles throughout the year, despite the changing conditions (pollen, falling leaves) of the environment. Calling a professional for a thorough job just before the photos are taken for your MLS listing and marketing pieces is a wise step, if you want to be sure your house goes on the market looking its best.
