"I suppose that if you call yourself "Dependable" right in your name, you have to live up to it, and Dependable David definitely lives up to it. First of all, he answers the phone and gets back to you. Sometimes, this is to tell you that he has no room in his schedule to take on your task. But at least he gets back to you to let you know. And if he does commit to doing work for you, he's there when he says he'll be there. He also does good, solid work. And he listens carefully to what you're asking him to do. If you ask him to be extra neat when painting, he'll be extra neat. If you ask him to tape everything, he'll tape everything. He bills by the hour, so this allows him to be more careful or take extra time to do something just right, if you ask him to. He doesn't need to rush, because he bills by the hour. He also doesn't farm out the work to a bunch of different guys. He shows up himself and does the work. In our case, he ended up swooping in and saving the day after our previous contractor made a royal mess of the job and had to be fired. So far, for us, he has done: --Mudding and painting a large room, including high ceilings and stair wells. --Mudding and painting an entire kitchen. --Installing natural (unpainted) Hickory baseboard molding in our entire 2-story house (including applying polyurethane to the molding before installing). This was an absolutely gigantic job (491 feet of molding), with so many cuts and corners, including some tiny detail areas where the new molding had to mate with existing woodwork (like around the staircase). --Framing, drywalling, and mudding a new hall closet. He also sourced the door for us. In this case, he only had one free day in his schedule, but he didn't over-promise, and told us that he would only have time to frame/drywall and do the first coat of mud (I would have to finish sanding, mudding, painting, installing the door, and trim myself). And he did exactly what he said he would do. All of this work has been great in terms of quality. David is also a friendly guy. He's fun to talk to. And he seems like the kinda guy you can trust in your home. But most of all... he's dependable!"

"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)"

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.
