"Rich, owner of RAP, and his dedicated crew did an awesome job in power washing our house, storage shed, deck, and brick walkways … everything is clean, bright, and frankly looking like new again! Rich is knowledgeable, responsive, punctual, professional, and an absolute pleasure to work with. He and his crew were meticulous in their work taking their time to do a job that well exceeded expectations and were conscientious in their clean-up efforts afterwards. It is indeed rare these days to see extraordinary focus on customer delight and pride in their work. I highly recommend Rich and look forward to working with him again in the future!"

"Great work by Exteron They installed a new chimney system for our fireplace and did a very clean, professional job. Everything was properly fitted and finished, and the fireplace is working great. The team was knowledgeable, respectful, and left the area clean when they finished. Very happy with the result and would definitely recommend them for chimney and fireplace work."

"Cesar and his crew just finished a remodel of my master bathroom. This is the second major project completed in my home by CSZ (prior kitchen remodel) and once again they exceeded my expectations. Cesar worked with me along the way to come up with the perfect design to ensure all my requirements were met. He is knowledgeable and his attention to detail is second to none. The CSZ crew, Armondo and Benjamin were also a pleasure to work with. They are knowledgeable, trustworthy, and hardworking. They also did an exceptional job cleaning up at the end of each work day. My dog even loves them! I highly recommend CSZ Construction. They will most certainly be back for future projects in my home!"

Deck Cleaning FAQs, answered by experts

Many composite decking manufacturers, including the popular Trex brand, offer warranties that protect against warping under specific conditions. These warranties typically last between 20 and 50 years, but they usually exclude claims related to improper installation of the product. Some manufacturer warranties only cover decks built by certified professionals.

Both deck footings and deck posts help prop up your deck. However, footings are the bottommost parts of a deck that touch the ground. They’re usually made of concrete. Posts are pieces of wood that attach to the top of the footings with brackets. They run upwards and connect to the underside of your deck to support its weight.

Wood decks need to be replaced every 10 to 15 years on average. Natural wood is highly vulnerable to infiltration and damage from moisture, which can occur rapidly due to exposure to outdoor elements. You can protect your deck and maximize its lifespan by sealing it every year or two.

Before installing a new railing, check the condition of the deck frame and joists, especially around the perimeter where posts attach. If boards are loose, soft, or show signs of rot, the structure may need repair. A deck pro can inspect your framing to confirm it meets load-bearing requirements.

When building an outdoor or deck gate, it's crucial to use durable wood that can withstand harsh weather conditions like sunlight, rain, wind, and snow. Redwood and cedar are excellent choices as they naturally resist decay. While redwood is considered more elegant, cedar is a more affordable option. Other suitable woods include oak and pressure-treated pine, which is specifically treated to resist rot. Although some softwoods like pine are popular, untreated softwoods such as pine and spruce should generally be avoided for outdoor projects because they are susceptible to damage from water, rot, and the sun. Ultimately, it's wise to consider your local climate when selecting the right wood for your gate.
