Why Alton homeowners choose Giani Exterior Services
Alton sits at the southern tip of Lake Winnipesaukee, and the combination of humidity off the water and the dense tree cover throughout town creates ideal conditions for algae, mold, and mildew to take hold on siding, roofs, and decks. Soft washing is the right approach here — high-pressure washing alone doesn't kill the biological growth, so it comes back faster.

What exterior cleaning costs in Alton, NH
Pricing depends on the size of your home and the scope of work. A typical house wash runs $300–$600.

We provide a free, no-obligation estimate before any work begins so there are no surprises.
Exterior cleaning challenges around Lake Winnipesaukee
Lakefront and lake-adjacent homes in Alton — particularly those along Route 11 and the Alton Bay area — deal with heavy humidity and shade from surrounding trees, which accelerates biological growth on all exterior surfaces. Roofs with northern exposure are especially prone to black algae streaking. Decks in shaded spots develop green algae and mildew quickly. Soft washing treats the root cause; standard pressure washing just blasts the surface and the growth returns within months.
