"They really did an exceptional job. The deck rebuild was a complicated job. The deck wasn’t built correctly originally so CM Contracting had to extensively modify the structure. They really did a great job. The deck looks really great, and I think I now have the strongest deck in the Lehigh Valley. The chimney work was a big concern of mine going into the job. The previous owner of the house let the chimney cap rust, and the rust stains ran down the Dryvit. It really looked bad. Chris worked with his paint supplier to get the color to match perfectly. He had Sherwin Williams out to my house on several occasions because Chris wanted it done right. It far exceeded my expectations, and now looks perfect. The caulking and power washing all went well too. I would highly recommend CM Contracting. Chris is very responsive. We would communicate often via phone or txt. His crew is great too. Very polite and friendly."

Deck Cleaning FAQs, answered by experts

The average cost to professionally clean or pressure wash a deck is around $150, with prices typically ranging from $100 to $600. Several factors influence the final price, including the deck's size, material, condition, and how long it has been since its last cleaning. For a smaller deck of about 300 square feet, you might pay around $100. For a larger deck of 1,000 square feet or more, the cost could be closer to $300 to $400. Decks that are very dirty or haven't been cleaned in years may require more time and special detergents, which will increase the price. The deck's material also plays a role. Wood decks often cost more to clean because they require a gentle power washing technique to avoid damage. Composite decks are typically less expensive to clean, and cleaning a metal deck may cost around $100.

A wood deck requires annual cleaning and regular inspections for loose or broken boards, nails, and screws. It should be refinished by applying a stain or sealer every two to three years to protect the wood from water damage, rot, mildew, and sun fading. The exact frequency can depend on the climate and the deck's exposure to sun and moisture. If your deck is painted, it will need repainting approximately every 10 years. Signs that your deck needs refinishing include faded, splintering, or warping boards.

The least expensive way to build a pool deck is with concrete deck blocks, pressure-treated lumber, and the appropriate hardware for hanging joists and securing deck boards. With these basic yet durable deck materials, you'll have a pool deck that's built to last without the high price tag. You should also stain or seal the deck to protect it against the elements.

In most cases, sanding an old deck before staining it is necessary to achieve a decent finish. If your old deck has a relatively new stain finish on it and you're only doing touch-ups, you can generally skip the sanding part. However, if your goal is to make the deck look and function better, sanding first is a must. 

It is recommended to clean your deck once or twice a year to prevent the accumulation of dirt, debris, mold, and mildew. The ideal times for cleaning are in the spring and fall. A spring cleaning removes grime that has built up over the winter, preparing your deck for summer use. A fall cleaning washes away messes from summer activities, preventing them from setting into the wood over the winter. The exact frequency can depend on factors such as how often the deck is used, its exposure to pollen, and whether salt was used on it during the winter. Regular cleaning helps protect the wood and its finish from damage.
