"I had a completed Bathroom update from shower, tile and tile flooring. To kitchen tile floor along with the Dinning room and Hallway. The quality of work this company did was Outstanding!! From quote of project to time line. I cannot say enough about the expertise of the workers which matched their work ethic. Always making sure every detail was on point and approved by me. A full Bathroom update plus laying over 300 square feet of tile with full demo of both areas. To come under 3 weeks speaks to the diligence of their work. Every detail was 5 star and I would highly recommend this company. Along with this review will be photos of the project ( they speak for themselves)"

"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."

"Reggie at St Germain Construction did an excellent job of siding my house and detached garage. He quoted me a fixed price, which included all of the major items as well as the small but crucial pieces that I didn't even know that I needed: outside faucet, electrical outlet, linen vent. The vinyl siding was carefully installed over Tyvek, and all the trim work was neatly done. I would definitely use Reggie again, and highly recommend his work."

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