"Russ was great to work with. He did a great job of picking out lights and flooring for me and even though he was booked with bathroom remodels he was able to fit me in in a timely fashion. His workmanship shows the pride he takes in his work."

"The work was fine, he did a nice job, in a small amount of time , he was willing to do the inside garage windows as well which I couldn't reach, he did that as well. Did it with a reasonable price and we've asked him to come back this fall."

Deck Maintenance FAQs, answered by experts

Staining and sealing the underside of a deck creates a moisture barrier but traps water in the boards, quickly leading to rot. No matter how well you seal the above deck, water still gets through via nails and screw heads on the surface. Allow this water to flow naturally under the deck, where it is routed through the drainage system.

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.

Yes, it is possible to add an under-deck drainage system to an existing deck by retrofitting it to the structure. This process may require some prep work. For example, many drainage systems are installed on top of the deck joists, which would require you to remove the decking boards and railings first. To avoid this, you could opt for a below-the-joist drainage system. For best results and to ensure proper installation, it is recommended to consult a professional. A pro can inspect your deck, make any necessary repairs, and then install the drainage system correctly.

Deck boards should be spaced no more than three-eighths of an inch apart. This is enough space to allow water and small debris to pass through without collecting on the surface, but not enough to create a tripping hazard. Certain materials, like pressure-treated wood, shrink over time, so they may need less space at installation.

If you have wood decking, there are several common deck problems that you might encounter. For example, your natural wood boards may fade over time due to things like sunlight, weather, and debris. On top of that, some types of wood decking can rot, grow mold, and attract destructive pests—including termites, carpenter ants, and woodpeckers.
