"We had a great experience. His price was reasonable. He responded to all messages. Was easy to schedule a visit to house to look at room we wanted painted. He promptly gave us an estimate and scheduled the job within 2 weeks. His work was fantastic. The room looks great. It was two colors with a chair rail separating. He was neat and cleaned up everything. He was polite and professional. Would definitely use again and recommend him to others."

"Juliano was very responsive and receptive of ideas I had for the project. The work done turned out the way I wanted and was able to do it within my price range. The only thing I would say needs improvement is the cleanup afterwards. There was more saw dust leftover than I anticipated. Regardless, I would recommend and would hire again for further projects."

Deck Maintenance FAQs, answered by experts

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

Before installing a deck, you must build a base for the deck to rest upon, often made of compacted soil or gravel. While gravel is an optional material, it helps with drainage. Some contractors also recommend installing a weed control membrane, which helps provide a solid foundation for the frame. In the case of an elevated deck, a pro will often lay down a concrete slab as a foundation. 

Yes, and in some cases, frozen ground may improve the digging process for footings due to sturdier conditions. It’s easier than working in muddy conditions, which are more common in the spring. Contractors may use machinery that makes this step a breeze, so harder ground shouldn’t affect the building process.

To flatten a cupped deck board, start by ensuring it’s dry. Then, try flipping the board over so the cupped side faces down and reattach it. If that’s not possible, you can use screws to pull it tighter to the joists or plane the edges slightly to reduce the cup. It’s best to replace severely cupped boards.

You can build an outdoor kitchen on a deck, but you should choose composite decking since it's more heat-resistant. Metal deck materials like steel and aluminum are also good choices because they're less flammable than wood. You should also consider the weight of the kitchen—make sure your deck can support it and any appliances you plan to use. You should consult a structural engineer to confirm exactly how much weight your deck can safely support when building an outdoor kitchen.
