"TDS provided excellent quality and service from start to finish. They removed the old brick chimney that was between the kitchen and dining room, and they did such an excellent job containing the demo debris that I didn’t even have to dust after! They also protected our existing flooring very well. You also can’t even see the patching on the ceiling. And at the end of the job, the PM let us know of a couple other issues he spotted in the attic (replacing vents) but didn’t pressure us in any way to sign them on for another project. I highly recommend them!"

"We have been using Madtown Homeworks LLC numerous times the past few months, and we nearly always had Jerry helping us. We were so impressed by the breadth of projects he could complete and his focus on good craftsmanship in his work. We also had Mike assigned to help us out once when Jerry was not available, and he was excellent as well. Most of our home improvement projects are now finished, but if another set of projects arise, we would call them again in heartbeat."

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