"I found Alex exceptionally careful and thorough. His pricing was fair. His work ethic was great. He cleaned our deck with a pressure washer. Because of his great job, we hired him to stain our deck. Great choice!"

"I called Modernized Exteriors, for a build bid on my new deck project, and they answered right away. Cameron came over with good ideas and pictures of decks that they already built. I told him I was considering Trex composite decking, because I wanted really low maintenance. He recommended Trex Transcend and I went with the Tiki Torch color. I accepted his bid on the spot. It took a while to get scheduled since it was the end of July. But when they were ready, it only took four and a half days to build my 12' by 20' deck. His crew is excellent and the finish project blew me away. It was so nice to have a project that came together so well in the end. Cameron and Nick came by the next day to make sure I was satisfied and to make sure the crew had cleaned up the work site. A job well done."

"Erick and his crew were prompt and courteous. They went out of their way to assure the job was done completely and to standard. Their taping and masking was exceptional providing great lines and definition. They paid great attention to details and went beyond to make sure the job was completed correctly. On top of the skilled workmanship they cleaned up the job above what was necessary. The cost was very very reasonable. I would not hesitate to use or recommend them. The crew was kind and respectful."

"I give the highest recommendation for Peter and Seatown Painting Solutions. Very professional. I had Peter do 4 painting projects at my house. Front Door Re-stained, outside beams re-stained, railings re-stained and deck rails painted. All projects look fabulous after completion. Peter was always very prompt, showed up when he said he would, cleaned up thoroughly during and after working his projects daily. Was exactly on budget and communicated very effectively about project. You can’t go wrong in my opinion using Peter and Seatown Painting Solutions."

Deck Cleaning questions, answered by experts

Building codes for deck railings can vary by location, so it's important to consult your local regulations before construction. Generally, a guardrail is required for any deck that is more than 30 inches above the ground.

For residential properties, the standard minimum height for a deck railing is 36 inches. However, some states and municipalities have stricter requirements; for example, California and Washington mandate railings that are at least 42 inches high. Therefore, a 42-inch railing is not considered too high and may be required in your area or chosen voluntarily for additional safety.

In addition to height requirements, codes also specify other safety features, such as the maximum spacing between balusters to ensure they are close enough to prevent a child from squeezing through.

Most building codes require that spindles or balusters on deck and stair railings be spaced no more than four inches apart. This safety standard, often called the '4-inch sphere rule,' is designed to prevent small children or pets from slipping through the railing. A good way to visualize this is that a 4-inch sphere should not be able to pass between two spindles. For the same safety reason, the space between the bottom rail and the deck floor should also be no more than four inches. As a general guideline, professionals often install three balusters per foot of railing. However, since specific requirements can vary by location, it is crucial to check your local building codes to ensure compliance before starting your project.

The proper height for a stair riser or deck step is between four and seven inches, with seven inches often considered the most comfortable. Building your stairs to this height ensures a strain-free step position and minimizes the risk of trip and fall injuries. For optimal safety and comfort, especially on deck stairs, a rise of around seven inches should be paired with a tread depth (or run) of at least 10 to 12 inches. While it is possible to design stairs with risers up to 12 inches, this height can be challenging for children, pets, or individuals with mobility issues. Always check with your local building codes, as they may mandate specific dimensions that differ from these general recommendations.

Your deck may look or feel fuzzy after pressure washing because the high-pressure spray tears some wood fibers as it removes the outer layer of dead and discolored wood. This fuzzy effect is a normal part of the pressure-washing process and will go away on its own in a few weeks. You can opt to spot-sand your deck if you’d like to remove it more quickly.

Both aluminum and composite decking materials are environmentally friendly, with aluminum decking coming in as the most eco-friendly option. 

Though composite decking helps remove plastics from landfills, recycles wood, and lasts longer than traditional wood decks, it’s not recyclable and only lasts for 25 to 30 years on average. Aluminum can last well over 30 years and is almost always recyclable.
