Best concrete driveway pros near Pine Brook, NJ

While DIY power washing is possible, professional services ensure thorough cleaning, proper pressure levels, and avoidance of surface damage.

There’s no legal requirement that states that you need rebar in a concrete driveway, but since the slab will be supporting heavy vehicle loads, it’s always a good idea to pay a bit more for rebar reinforcement. Your driveway will be much more likely to crack if you don’t reinforce it with rebar. Driveways that need to support commercial vehicles or provide parking for multiple vehicles at once should always include rebar reinforcement. If you’re pouring concrete over asphalt or pouring concrete over an existing slab, you may not have enough depth for rebar, meaning an increased risk of cracking.

You should avoid using a pressure washer on any surface or item that could be damaged by the high-pressure spray, as some materials are too delicate to withstand the force.

Key items and surfaces to avoid include:

• Electrical Components: Never pressure wash electrical systems, as water can cause short-circuits and create a safety hazard. This includes utility meters, breaker boxes, electrical outlets, generators, and HVAC or air conditioner units.

• Delicate and Fragile Materials: Fragile items can crack, shatter, or be stripped by the pressure. Avoid pressure washing windows, glass, light fixtures, shingled roofs (especially asphalt), and stucco.

• Painted, Stained, or Sealed Surfaces: Unless your goal is to strip the finish, do not pressure wash painted surfaces, stained wood (like decks), or anything with a protective seal that could be stripped away. Be especially cautious with older surfaces that may contain lead paint.

• Soft Woods and Certain Decking: Delicate surfaces like softwood, composite decking, and antique or wooden patio furniture can be etched or damaged. If you must wash wood, use a lower-powered pressure washer with a wide-angle nozzle to prevent damage.

• Living Things: Never use a pressure washer on people, pets, or plants. The force can cause serious injury and will destroy landscaping.

Pressure washing your driveway can prevent cracks in it since it removes grease and oil, which, if left on the driveway for too long, can break down compounds in concrete and asphalt, leading to cracks. It can also help keep driveway weeds, moss, mold, and mildew at bay while boosting your home's curb appeal.
