"Despite a spring of constant rain, Vince got the decks and stairs cleaned and in the case of the upper deck, sealed, in time for a large family party as I'd hoped. He pointed out where the wood has been compromised and thus recommended sealing those boards as well. I appreciated his attention to all aspects of the project. I plan to hire him each year for maintenance going forward."

"Best company I ever used for my back deck restoration and staining! Technicians were on time, polite and very professional! Estimate I got from this company was very reasonable and we agreed to start the work immediately, and now my deck looks amazing and I will definitely hire this company again in future! Highly recommended!"

"They do excellent work. I have had the exterior of my house cleaned twice by them. They arrived promptly. They thoroughly cleaned the exterior so that it was clean enough to paint the trim-work. We had spider webs under the eaves which are very hard to remove, but they got them all off. They use a method that is different from typical pressure washing. We had pressure washing previously and it broke the seals in some of our windows that then had to be replaced. This company does not do that."

"We hired Carlson based on other customers' reviews on Angie's List. We were about to put our house up for sale and needed to make it look attractive to potential buyers. This company is outstanding! Weather was raining on the morning of the appointment, and I was sure they wouldn't be able to perform the jobs in such conditions. But, to my surprise, the crew leader Dave arrived and said he had viewed weather radar and it looked like the storms would pass, allowing his team to do the contracted work. The end results exceeded our expectations to the max! Outside power washing just didn't include cleaning the siding. The crew even washed under the eaves and the outside of the rain gutters! We contracted for their best level of window cleaning, which included cleaning the glass inside and out, cleaning the screens, and even wiping around the sills and cleaning out the window frame tracks. When everything was done, the entire house sparkled! I'll use Carlson again in the future, and will strongly recommend them to other family and friends."

"We had a 750 sq foot elevated deck built by Joel and the building team led by Matt. Joel was fantastic to work with from his first visit, design proposal and quote. The building team led by Matt did extremely high quality work and were great to design with as the project progressed. They were very neat and hard working. We were delighted with the overall experience, result and value for money. We would definitely work with them again and highly recommend them."

FAQs for deck, fence, patio or porch clean and seal projects in Fontana, 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.
