"Great experience with this company. They power-washed, sanded, and sealed our garden stairs and little deck. Cosme was knowledgeable, polite, and always answered my texts promptly. He and Gustavo did the work for a very reasonable price and it looks great! Thank you, Cosme and Gustavo!"

"Jonathan team was fantastic! They completed our deck replacement project on time with no surprise costs and with great communication throughout the project. We were able to address multiple issues and smaller projects that had been languishing on our to-do list for years as part of the larger deck replacement, and we will absolutely keep Collazo in mind for future home repairs. 5/5!"

"Oh, boy--Erick (and Tom, his guy) have done work for me on my 100-yr. old home, for over a decade! First job -- Erick alone--built a gorgeous deck...neighbors couldn't stay away. ...still getting compliments. Last two big jobs-- redid garage and installed electric doors, and custom tiled a bath everyone else wanted to "demo". . In-between took care of several other problems as they came up. Ask them for my phone number and I will tell you more. Absolutely nobody compares in terms of ease of communication, (and creativity) so you actually get what you want, or better."

"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!"

"They came out to give me a quote immediately & started the job 2 days later. Reliable, on time and went the extra mile by helping to move the rest of my furniture, etc. off my back patio that I couldnâ t move myself. Good communication and great work. ( Work performed: Power washed stamped concrete patio thoroughly and gloss sealant applied once dry)"

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