"I was very happy with Advance Cleaning’s work. I had water coming into my basement after a lot of heavy rainfall, so I knew I needed to deal with my gutters. Yanks was very responsive, scheduling was quick and easy, and he and his associate were on the job very fast! They worked nonstop on a very hot day and made sure all the downspouts were flowing freely before they finished. Everything works and looks really great after their work."

"First, Matt showed up which was 99% better than anyone else I contacted. I used him from straightening a weather vane to fixing a place on my roof to repairing and painting my front door surround to putting in a couple of windows. His work is exacting and very well done and done when he said it would be. I certainly would hire him again."

"I felt that the carpets were cleaned very well. No stains remained and the carpet looked fresh. Unfourntatly there was an odor to the home after the carpets were cleaned and becuse i had them cleaned professionaly because i was renting that home and was moving out and went with Tile techs so i could be assured the landlord wouldnt charge for carpet cleaning. That didnt happen that way. i received an email stating the carpets had an odor and they were considering having the carpets re-cleaned. I had to shut the windows that afternoon after the carpets were cleaned because a storm was coming. The house didnt have proper time to air out."

Deck Maintenance FAQs, answered by experts

It’s important to make sure the wood on a new deck is properly seasoned. Seasoning a deck is simple: Once you build it (or have a pro do so), just leave it alone so it can acclimate to the environment. If you don’t give the deck proper seasoning time before staining, the stain can lock in any lingering moisture and cause mold, rot, and other moisture issues down the road. Give the wood at least four to eight weeks to season before you stain.

A deck that isn’t attached to a house is called a floating or freestanding deck. These standalone decks are built near ground level, so they usually don’t need deck stairs. Some don’t even require permits. Generally speaking, building a floating deck is faster and more DIY-friendly than constructing one that’s connected to your home.

To flatten a cupped deck board, start by ensuring it’s dry. Then, try flipping the board over so the cupped side faces down and reattach it. If that’s not possible, you can use screws to pull it tighter to the joists or plane the edges slightly to reduce the cup. It’s best to replace severely cupped boards.

Typically, most residential wooden decks are designed to support approximately 40 pounds per square foot, including the deck’s weight and any items placed on it. While this is fine for typical use, it is usually not enough to hold the weight of a hot tub filled with water and people. To safely support a hot tub, your wood deck will likely require reinforcement. Therefore, it’s best to have a contractor or a structural engineer assess it before hot tub installation.

You do not have to dig footers for a deck as long as it meets local code and holds up to weather in your area. If you live somewhere that experiences high winds and earthquakes, you may need to dig for your deck posts. Deck blocks, post anchors with base plates, and helical pile systems are the three no-dig deck post options you can choose from if local code permits.
