C&G Painting Company LLC provides top-notch exterior and interior painting services in Oshkosh, Appleton, and Green Bay. Our team offers quality service at an affordable price. Contact us today for an estimate!

"When I contacted C&G Painting Company LLC, Carlos provided a same-day estimate for painting the exterior of my brother's very neglected house that was built in 1939. The crew arrived the day after we agreed on the price, power-washed the house, made repairs as needed, and painted the house. How they managed to make the house almost look like new is a miracle. Despite having to travel 20 miles outside of Menominee, Michigan, this crew completed the work in 3 days. If every painting contractor provided this type of exceptional service at a very reasonable price, everyone with a frame house could keep it looking beautiful. I highly recommend C&G Painting Company LLC."

Family-owned since 1984. We are a one-stop General Contractor specializing in Windows, Roofing, Siding, Doors and Sunroom Additions.

"We hired them to replace the aging siding and windows on our home. They were not the least expensive nor the most expensive, but AJ and his team took the time to truly understand what we were looking for and needed during the project scoping stage and delivered exactly what we were looking for and on the schedule we needed it. I performed some other renovation work that needed to be coordinated with their work, and all went great. AJ, Eric, Nick, and their crews are down-to-Earth folks and are genuinely looking to do a good job and make their clients happy. I would hire them in a flash for any future work and highly recommend them! Gene F."

FAQs for deck, fence, patio or porch clean and seal projects in New London, WI

You should clean your deck before sealing it. Cleaning before refinishing is critical. If you don’t remove dirt and debris, you'll trap moisture in the wood, which prevents the new sealer from working correctly and can lead to costly repairs. Whether you need to sand, power wash, or sandblast depends on your deck's condition.

Sealing and staining your deck are essential maintenance methods that protect and beautify your outdoor space. Stain adds rich color and guards against fading, while sealant fortifies the wood against moisture and weather damage. Wood type, climate, deck age, and the degree of existing damage determine whether your deck benefits from one or both treatments. Using both options extends your deck’s durability and enhances its overall appearance.

Power washing and sealing your deck costs $500 to $1,700. This process combines the removal of stubborn dirt and debris with a protective seal that preserves the wood’s integrity. Effective cleaning eliminates harmful buildup, and a proper seal prevents moisture damage and wood decay, ensuring long-term durability and reducing future repair expenses.

Your deck must be sealed every one to three years to maintain its strength and appearance. Regular sealing is essential to protect the wood against moisture, mold, and harmful UV rays. A consistent sealing schedule prevents rapid deterioration and costly repairs. Inspections should be performed annually to determine if the protective layer remains intact, extending the life of your deck.

Leaving your deck untreated compromises its structural integrity and safety. An unprotected deck rots quickly due to moisture and environmental exposure, which means that neglecting sealing results in rapid decay and expensive replacement costs of $4,125 to $11,650. Sealing your deck is essential for maintaining its durability and protecting your home.

The sealant on your deck dries within a few hours and reaches full cure within 72 hours before regular use. It is essential to wait until the complete curing period to ensure the protective layer fully sets and resists weather and foot traffic. Proper drying guarantees that your deck is fully protected against moisture and environmental damage, ensuring lasting quality.
