"Johnston General Contracting did very fine work on power washing and sealing my deck. The deck looks great. While he was late on the first day of the job the second day he was right on time. I would recommend this company. The only negative would be that the price seemed on the expensive side."

"Steve (owner) immediately returned my initial call, was out to do the estimate the next day, and completed the work the morning after that.  He and his partner did a beautiful job.  They were friendly and professional, and I was so impressed with their work.  Everything came up so clean, from the rain gutters to the aluminum siding to the concrete just beneath it at the base of the house.  The sidewalk is a completely different color now!  And they even pressure washed the straw doormat I had on the front porch!  I've made arrangements for them to return in the late fall or early spring (when the trees aren't dropping so much stuff) to pressure wash, protect, and paint my deck.  Steve talked with me about deck protection and the product he recommends using and provided me with a chart of color samples.
I would absolutely recommend this company to anyone who needs pressure washing.  I felt like their performance, in every respect, was flawless.

Deck Maintenance FAQs, answered by experts

Yes, but ensuring the deck has a solid foundation with adequate footings is critical before building, as the weight of a sunroom will put significant pressure on the structure below. Even if your deck is properly constructed, it may not be able to handle the extra weight. While some basic, lightweight, prefabricated sunrooms can sit on a deck with a strong existing foundation without additional supports, in many cases, the foundation and joists will need reinforcement. It is always best to have a structural engineer perform an inspection to evaluate the deck's quality and structural integrity. A professional can help you decide if reinforcement is sufficient or if it's better to tear down the deck and start over.

Floating decks are a cost-effective and versatile option, but they come with some compromises. Since they sit on smaller footings instead of being deeply anchored, they’re more likely to shift over time, especially in areas with heavy rainfall or freeze-thaw conditions. Their low-to-the-ground design makes them more susceptible to moisture buildup and potential water damage.

Footings for ground-level decks need to be at least 12 inches deep, and some areas require them to be even deeper. A standard range for deck footings is anywhere from 12 to 48 inches. The minimum footing depth is determined by an area’s frost line and soil conditions. If you’re unsure how deep to install deck footings, check local building codes to find the minimum footing depth in your area. 

Ultimately, overapplication of stain can compromise the deck's appearance, durability, and longevity. It may result in an uneven finish, with excess stain pooling, dripping, or drying into thick patches. It can also obscure the wood's natural grain and texture, detracting from the desired aesthetic. Moreover, excessive staining may not fully penetrate the wood, leading to poor adhesion and premature wear. Additionally, thick layers of stain are prone to peeling, cracking, and blistering as they struggle to bond with the surface. 

Composite decking is the best material for individuals living with disabilities who want to age in place. The material is anti-slip, which increases safety throughout the year. It’s also highly durable and requires minimal maintenance, so it doesn’t add another item to the individual’s to-do list. It’s also a good option for improving wheelchair accessibility at home, as it can easily manage a wheelchair ramp.
