"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"These guys did a great job. Our deck has a lot of railings and posts, and it is a bit of a pain to power wash; but they cleaned it down to the last rail. They even did the grill cover and mat. They also got rid of all the tree sap and drippings on the fencing. They were a couple of minutes late because they got caught up in rush hour traffic, but they made up for it by power washing some things that were not included in the original estimate at no additional charge. Their pricing was competitive with all the other estimates I got. Definitely recommend."

"Very pleased with the work done by Jonathan Fiske. Jonathan delivered the door which we painted ourselves. When it was ready, Jonathan came out within a few days and installed the frame, door and moldings in one day. He also replaced the alarm sensor, made sure proper flashing was installed and took the old door away. He answered all questions that we had. It was a pleasure working with him and would recommend him to others."

"I wrote the C review. 3 years later, the windows leak every year and there is a leak in another room under the roofing that Sean "fixed." I have just learned that there are holes (where he put his scaffolding) above the leaking area. The windows were new and the only leaks are below the holes. I have spoken to other roofers who say it was a very poor job and should be redone."

FAQs for deck, fence, patio or porch clean and seal projects in Gilmanton, NH

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.
