"After I met Stuart, the owner of Summit painting, I knew I wanted to hire him for my painting needs. He was very professional, knowledgeable, competent in his line of work and just a really likeable guy. I was very comfortable with him and knew it would be a good fit. We discussed the scope of work which included painting and staining of a brand new stair case (along with interior walls) and he understood my expectations. I received a very clear bid from him that outlined in detail what the job included and any potential additional charges, which I appreciated. When painting day came....I couldnt have been any happier. His guys were amazing. They were on time, extremely professional, friendly, clean and tidy, efficient and amazing painters. They all worked so well together. I just have to say I was amazed at how much care they took to cover and protect all of my furniture. I just hand my kitchen remodeled and they were meticulous in their care. I am in love with the paint job and I am so glad that I trusted my gut and went with Summit painting. I plan to have them back to to paint my upstairs bedrooms soon. You will not be dissapointed. I'm thrilled."

"We built a new deck on our 1970 house in Shoreline. Cameron and his crew (Dale and Ryan in particular) are awesome to work with. Top notch quality work and we love the finished product that will last for many years to come. The team built the deck in record time - minus the railing which was contracted to another company. My frustration was with the railing company (apparently had not worked with them before). The glass railing took 3.5 months to deliver when they had quoted 3-4 weeks… and the communication on the shifting dates was spotty. This was also around the time of the massive heat wave this summer so some of the boards understandably started bowing and expanding - Dale came by each time and made sure to fix any issues. Really appreciated it."

"Mark and his team were wonderful to work with, timely and responsive. A year after they finished my house painting and deck staining, some stain had worn off my steps. Despite being past the standard Warenttee, Mark arranged to have the area touched up and even bought me the stain!"

"Brett demolished our old, wood deck and replaced it with a new, composite deck. He utilized a two-color design. It looks great and is an asset to our property. Brett did the work in a professional manner. He was up-front about how best to lay the different colors of composite. He did a great job!"

We felt informed and supported throughout the entire project. We wouldn?t hesitate to use them again or recommend them to friends and family."

FAQs for deck, fence, patio or porch clean and seal projects in Mountlake Terrace, WA

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.
