"Good value and good communication. Marco was able to start our re-decking project early due to weather conditions. He was very flexible with respect to keeping costs low, but refused to sacrifice quality. Late on a Friday he ran out of full length boards, and even though Iâ d approved allowing him to piece boards together, he decided to go back and get more wood since he didnâ t think weâ d be satisfied with the end result. He did this even though he knew it would delay the start of his weekend. Weâ re very pleased with the end result! Weâ ve recommended him to a number of people in the homeowners association."

"Haven Landscape did a great job. After they completed the project you would have never known that a trench and drains were installed in the yard. Everything was restored perfectly. They identified the problem and resolved the issue."

Deck Maintenance FAQs, answered by experts

Routine cleaning, sealing/staining, and inspection prolong deck life and appearance.

You can nail or screw composite decking, but 3-inch decking screws are the better fastener choice. Unlike nails, decking screws won’t back out of the composite material over time. There’s also little danger of splitting composite material when driving screws, so you don’t need to pre-drill holes unless otherwise recommended by your decking manufacturer.

Applying too much sealer to a deck might seem like extra protection, but it can cause more harm than good. Wood is a porous material with a limited capacity to absorb liquids. When you go overboard with sealer, the excess can't soak in and instead forms a film on the surface. This leftover layer is prone to peeling, cracking, and trapping moisture, ultimately defeating the purpose of sealing in the first place. 

Two coats of stain are ideal for the best protection and aesthetic appeal. However, if your decking is made of particularly dense hardwood, you may only need one coat. If you want an intense color, two coats are ideal.

Any wood deck provides some ventilation to the area below, as is the nature of that type of deck design. However, areas that experience excessive humidity and associated moisture benefit greatly from a dedicated ventilation system in the form of strip vents. This addition helps the various wood boards contract and expand evenly throughout the years and reduces the chances of twisting, warping, and buckling.
