Brady is the best you'll ever find for home remodeling projects.
Showed up on time. Took the time to make ever job right.
Projects were worked on over a number of months, one at a time.


The best and most honest tradesmen I've ever found.
We moved to Texas in January of 2014.  We whish Brady could have come with us.
I've found some good (and bad) people to work on the Texas home.  But no one who comes close to the quality of work done by Brady Brower.

"Nate did an amazing job power-washing the siding on our house! It looks brand new again. He always returns calls and messages very promptly. He also showed up on time, was very communicative, and super friendly. We will definitely be hiring Fresh Fleet for any further power-washing needs we have, and I highly recommend them to anybody else in need of their services!"

Deck Maintenance FAQs, answered by experts

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. 

Yes, you can build a deck over your outdoor HVAC unit, but you need to leave at least 5 feet of vertical clearance above the unit. If you don’t want your deck to be that high off the ground, you could build a floating deck in another part of your yard—again, as long as you leave at least 4 feet of horizontal space between the deck and your AC unit.

The choice between Trex, a brand of composite decking, and PVC decking depends on your priorities regarding budget, appearance, and environmental impact. Both materials are durable and resistant to moisture and insects. Trex is often considered more eco-friendly because it contains recycled wood and plastic and is 25% recyclable, while PVC is fully synthetic and harder to recycle. Aesthetically, Trex is designed to look more like real wood, whereas PVC often has a glossier, more plastic-like finish. In terms of cost, Trex is typically less expensive than PVC.

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.

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.
