Just like having the chimney cleaned every year or lawn fertilized, pressure cleaning should be an annual service to maintain your home. When done annually, it can eliminate contaminates that contribute to rot, decay and premature aging of your home’s siding and building materials. Here in New Hampshire, because of all the lakes, ponds, and trees, we experience a high rate of mold. When untreated, that mold can eat away at your siding or deck. Pressure washing can truly add years of life to your property and save money on costly repairs.
