"My new deck is beautiful, the quality of work is outstanding. Jonathan and his crew were professional, hard working and easy to work with. They came every day even in the extreme hot weather, cleaned up after themselves and built a great deck. I have recommended Collazo builders to my friends and would use them again for any projects I have."

"Flowers Garden Services did a fine job cleaning our gutters. Marisol and Oscar, the owners, showed up right away, gave us a fair quote, and returned in two days to do the job. I will use them again for gutter cleaning and other household services they perform."

Customers say: Quick response

"I had Dave add a sunroom to my home and it was better than expected and I think will now be the main area that we spend most of our time in! Dave is an excellent communicator, always notified us of changes or unexpected issues, showed up ON TIME and if he couldn't show up let us know as soon as he knew. He and Mark were always professional, friendly and most important trustworthy. I've had him do other projects and plan to have him back again. For those that complained his costs were too high, I'll say that you get what you pay for. His prices are fair and the work is impeccable."

"I had a great experience with HORIZON HOME IMPROVEMENTS. They repaired an issue with my door that wasn?t closing properly. Aleksandr was very responsive, professional, and easy to communicate with. The technician arrived on time, quickly figured out the problem, and made the necessary repairs. The door works perfectly now, and everything was left clean afterward. The pricing was fair, and the whole process was smooth. I would definitely recommend them for any home repairs!"

FAQs for deck, fence, patio or porch clean and seal projects in Northborough, MA

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.
