We hold on to one very important word here at Schleifer’s WoodWorks LLC… Integrity. This company is built on it. When we started out on the idea of building “another construction company” we knew we had to be different. Together, Corey and his team have 30+ years in construction and a wealth of knowledge in over 20 trades and specialties. With all of our history living, working, and loving these Twin Cities, we needed to bring out the best in our fields. One of the biggest problems in construction today is the lack of attention to the customer… YOU! We take jobs one by one to ensure we get it done right, the first time. We pride ourselves on our experience and aim to bring “the craft” back to craftsmanship. Let’s get connected.

"The only thing I was dissappointed in was that the deck has a rough finish, but I suspect that was due to the previous sealing that was done by someone who wasn't experienced (family friend).  This guy said they could buff it next time, so that's OK.
They were very responsive to a spot that appeared to not have taken the stain as well as the rest of the deck surface; they came back right away and resolved that."

"We have a large home built in 1900. There were many coats of chipped paint and wallpaper throughout. Dennis Nagel and his crew did a fantastic job stripping wallpaper, sanding the many coats of paint off the woodwork and patching all the large cracks in the ceilings. The finished walls and ceilings are flawless. Dennis recommended paint colors, repainted the entire house and it is transformed and beautiful. They worked long days, during very hot weather, without air conditioning in the house. Dennis has a strong work ethic and takes pride in what he does. He will go that extra mile to do an impeccable job."

"OK. She left for 3 hours to do another job then rushed to finish the deck when she returned. I was not happy with the overall look. I know our deck was very dirty, however she missed several spots."

"One structure in the form of a arbor with a gate completed our fence.
     The other structure a small deck outside of the lower sliding glass doors, with a pergola added,
     gives a quiet shady respite to the yard.
      We also had Hal design and build a fountain feature added to the garden area itself.  Which gives a soft
      and flowing water sound near the small deck.
      The work overall is outstanding with a very finished look.  It was also accomplished as per estimate of
       time and cost.  They were very considerate to make the work space neat and clean each day at finish
       time.
     
       We would "highly" recommend these contractors to anyone wanting this type of excellent yard work done.

FAQs for deck, fence, patio or porch clean and seal projects in Randolph, MN

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.
