When contacting other power washing companies in the area, make sure that they have adequate training from an organization in the industry. Most power washing companies in the area practice the aim and BLAST method of cleaning, instead of learning the proper procedures. This results in un-trained day laborers that learn how to power wash while on the job which can cause severe personal injuries and damages to your home! A power washer in the hands of someone without the proper training is a nightmare for the unsuspecting home owner. So ask the basic questions below to hire a reputable power washing company. Any reputable company will have a working knowledge of the right soaps and detergents that should be used when power washing your home or deck, the amount of pressure that should be used and the answers to the questions below.

Questions To Ask Power Washing Companies!

Is your power washing company licensed, bonded and insured?

The current regulations from the Maryland Home Improvement Commission require licensing for sealing decks and for using soaps and detergents, not high pressure cleaning. Most damage is caused due to improper use high pressure. A contractor with an MHIC license offers some protection from the Maryland Home Improvement Commission. If you use a pressure washing company that does not have an MHIC license, you may have no protection at all.

What type of deck sealers do you use on wood surfaces?

Manufacturers spend millions of dollars a year to promote their products but they don’t tell you that linseed oil, (one of the most popular oils in deck sealers) is actually food for mildew! They also don’t say that surface coating agents which are usually found in hardware stores, may actually allow wood to rot or cause problems to the woods natural fibers.

PWC Response:

We use Ready Seal. Nationwide polls taken by wood restoration professionals have chosen Ready Seal as one of the most popular brands of deck sealers used by power washing companies for the last 8 years in a row! This sealer provides outstanding protection for wood surfaces and comes in a variety of colors.

Do you use professional grade cleaners that are designed for the surface you are cleaning?

Many pressure washing companies use home made recipes, bleach or other products from big box stores for cleaning decks and other services. Some of these products can cause damage to the decks and other surfaces if not used properly. Bleach for example, should never be used on wood! Any professional power washing company will always use products made for the pressure washing industry. These products are designed to give better results and outperform products from local hardware stores. If your paying for quality service, you deserve to get the best products and results possible!

PWC Response:

We use professional grade soaps, deck sealers, equipment and pressure washing supplies purchased from Sun Brite Supply in Gaithersburg Maryland.

Did the company ask for more than 1/3 for a deposit?

Requiring a deposit on a contract is common. Most contractors require it to schedule the job and to purchase the materials for the job. In Maryland, a company is only permitted to receive 1/3 of the contract in advance as a deposit. If a company requests more, contact the Maryland Home Improvement commission at 1-888-218-5925

PWC Response:

In rare cases we may require a deposit to schedule work.

Does the power washing company have references?
