"I was very happy with Advance Cleaning’s work. I had water coming into my basement after a lot of heavy rainfall, so I knew I needed to deal with my gutters. Yanks was very responsive, scheduling was quick and easy, and he and his associate were on the job very fast! They worked nonstop on a very hot day and made sure all the downspouts were flowing freely before they finished. Everything works and looks really great after their work."

Deck Maintenance FAQs, answered by experts

Composite decking boards aren't your only options for building a deck. There are several other types of materials for decks, including wood and aluminum decking. Wood decking comes in many different wood species, offering natural beauty and classy timelessness to your yard. Aluminum is a lightweight, water-resistant, and low-maintenance material that is also non-slip.

Both composite and PVC decking are excellent alternatives to wood. However, while composite is moderately priced and lasts around 30 years, PVC costs more and lasts longer. PVC is also more durable, though both materials are more durable than wood decking. Ultimately, the choice between composite and PVC decking will come down to your budget and preferences.

The life expectancy of deck boards varies widely based on the material, climate, and maintenance. Untreated wood boards typically last 10 to 30 years with proper care, while pressure-treated boards can last up to 50 years. Hardwoods generally outlast softwoods. Composite boards also tend to last longer than natural wood. Environmental factors like arid or humid climates can shorten a deck's lifespan. To extend the life of wood decking, it's important to consistently clean and seal it to protect against moisture, UV light, and insects.

Rot loves moisture, so deck rot typically impacts the parts of a board that stay wet. This includes the underside of boards, in addition to support posts and joists. However, any part of a board can rot, given the right conditions. 

With proper installation and maintenance, a vinyl deck can last up to 30 years. Factors like regular cleaning, minimal wear and tear, proper installation, and the use of higher-grade materials can extend its durability. However, extreme weather conditions or neglecting maintenance might shorten its lifespan. Adhering to manufacturer recommendations for care and occasional inspections can significantly prolong a vinyl deck's longevity.
