Services
Pressure Washing
Our pressure washing services remove algae, moss, and grime from surfaces using biodegradable solutions and precision techniques. We specialize in preparing surfaces for painting or staining by eliminating chalking and dead wood fiber. Clients benefit from restored curb appeal and extended material lifespan for siding, decks, and masonry.
Roof Restoration
Roof restoration addresses moss, algae, and lichen buildup that damages slate and asphalt shingles. We apply detergents and mildewcides followed by low-pressure washing to prevent granule loss. This process extends roof longevity by eliminating moisture-retaining growth that causes cracks and decay in New England's climate.
Siding Restoration
Siding restoration services clean vinyl, aluminum, and painted surfaces while preserving material integrity. Our techniques remove chalking, mildew, and weathering without high-pressure damage. Clients receive thorough disinfection before repainting or staining, ensuring proper adhesion and long-lasting results for both residential and commercial properties.
Deck Restoration
Deck restoration services rejuvenate wood surfaces by removing dead fiber and applying protective treatments. We use specialized brighteners and preservatives to restore natural beauty while preventing future decay. Clients benefit from cost-effective maintenance that extends deck lifespan and enhances outdoor living spaces without replacement costs.
Patio Maintenance
Patio maintenance services clean stone, brick, and concrete surfaces using algaecides and high-pressure washing. We remove tree sap, pollen, and moss buildup that creates fertile environments for growth. Clients receive optional sealing services to prolong surface life and reduce future maintenance needs for both residential and commercial properties.
