"Have now used Ultimate Cleaning Specialists for a couple of jobs this year. This time he stained our front deck/ramp that he had pressure washed in the previous job. He worked very hard as it is a "Large" deck/ramp and did an excellent job. I would recommend this business for anyone. Very professional, friendly and very contentious in his work! Very happy with results "Thank you Nic"!"

Customers say: True professional

"Carter Clean did a tremendous job power washing and staining my decks and porches, restoring them to beauty after years of neglect. It was a very big project and Alex and Bill were always on time with no delays in completing the project in a very timely manner. Both were super professional, responsive and hardworking. They take pride in their work and treated our home like it was their own, including going above and beyond the agreed upon work when they saw something that needed repair, additional cleaning, or even to help trouble shoot solutions to a pesky wood pecker problem. Bill did an exceptional job cleaning the roof. He was very efficient and brought the roof back to its original beauty, despite it being nearly 20 years old. He additionally went above and beyond to clean the sidewalks in front and back without any additional charge. Thanks to Alex and Bill the exterior of the house looks great again. Iâ d use these guys again in a heartbeat. They were competitive in their pricing, absolutely fabulous, and I would highly recommend them to anyone."

Deck Maintenance FAQs, answered by experts

Constant exposure to inclement weather conditions can damage your deck, causing it to fade, warp, or crack over time. Regular maintenance keeps it looking and performing its best. That means giving it a good cleaning and applying a quality sealant or wood treatment to help defend against moisture, sun damage, and everyday wear.

The best base materials for a ground-level or floating deck are typically gravel and crushed stone (also known as landscaping rocks). These options are inexpensive, provide excellent drainage, prevent weeds, and help minimize moisture buildup, which reduces shifting and rotting. For added stability and to evenly distribute the weight, you can use concrete deck blocks or pavers. While more expensive, concrete blocks and pavers offer a sturdier base than gravel or crushed stone alone.

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.

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.

A deck doesn’t have to be perfectly level. Many pros even recommend a gentle slope to ensure proper drainage and increase longevity. The ideal gentle slope is about 1/8 to 1/4 inch per foot away from the property, leading water away from the home to prevent pooling and reduce the risk of damage. It also minimizes rot, mold, and other moisture-related problems.
