"I hired Cody for so many projects! He painted my roof, the outside of my house, detailed work inside. He re-glazed my windows, sanded and painted my ceilings, repainted my radiators, and more. His work is perfect and detailed oriented. He also staged my house painting over the course of the summer in order to make it easy for me to pay for it. Cody is also extremely polite and pleasant to be around. I highly recommend him."

"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."

"They were very professional and dedicated. Some of the decks were in pretty bad shape. They stayed on it until all old mold was out. One of them was in sch bad shape that when it was wet it was dangerous. Well now it looks like new. Very nice work. Thank you!"

"We cannot say enough great things about Cully and his crew.  He was prompt in providing his initial estimate and provided us with a detailed description of the work details and its cost. He was conscientious about creating debris and cleaned throughout the process. Overall, the job took over a month due to weather. We are very pleased with the work that was done."

Deck Cleaning FAQs, answered by experts

The best direction for a gate to swing depends on its location and purpose, but swinging inward is the general rule. An inward swing is often considered safer, prevents the gate from opening into public spaces like a sidewalk, and may be required by local building codes.

There are exceptions and specific considerations. If your property is on a slope, an inward swing might not be possible. For a deck gate, it's safest to have it swing away from any steps. In a backyard, the direction can be a matter of preference, though an inward swing can be helpful when carrying heavy items like a wheelbarrow into a garden.

Regardless of direction, ensure the gate can open fully without hitting any objects or blocking spaces. While an inward swing is standard, a gate that can swing both in and out offers the most flexibility if your setup allows for it.

It is possible to pressure wash your deck, but it’s usually best to leave the work to a professional for two main reasons. First, power washers are expensive, and you can avoid high upfront costs by hiring a deck washing pro instead. Second, you must be careful to use the correct setting to avoid damaging your deck material. You can only clean soft woods like pine with a wide spray and a low pressure; otherwise, the water will leave unpleasant marks on your deck. Hard woods, composite material, and metal can stand up to increasingly higher water pressures.

A deck that isn’t attached to a house is called a floating or freestanding deck. These standalone decks are built near ground level, so they usually don’t need deck stairs. Some don’t even require permits. Generally speaking, building a floating deck is faster and more DIY-friendly than constructing one that’s connected to your home.

A sunroom will add more value to your home than a deck, but with a much higher up-front cost. Depending on its construction and function, a sunroom may be counted as additional living space, while a deck is strictly an outdoor feature. Both will increase your home’s value, but the sunroom will have a much bigger effect.

Because adding a deck will yield a higher property value, you may have higher insurance costs. It’s important to follow the codes and regulations set by your local and state governments, so your insurance rates can be properly calculated. You may need an insurance revaluation after your deck is completed. The best course of action is to speak with an insurance professional to understand how adding a deck will impact your home’s insurance costs before you begin.
