Power washing is a great way to get rid of built-up dirt, mould and grime on your home’s exterior surfaces but there are times when it can do more harm than good. Before you fire up that power washer it’s important to know when you should not pressure wash your house to avoid damage and costly repairs. Excessive pressure on delicate surfaces can be irreversible and improper pressure washing techniques can cost you more. In many cases it’s better to hire a professional cleaning service to get the job done safely and right.
Before You Power Wash
1. If Your Home Has Old, Delicate Siding
Older homes with delicate surfaces or composite siding like wood siding or vinyl can be damaged by high pressure from a power washer. The water pressure can strip away coatings, loosen panels or even crack siding and cost you thousands of dollars to repair. Using the right nozzle and pressure setting is key when dealing with older homes to avoid damage.
2. In Freezing Temps
Power washing in cold temps can cause immediate freezing and ice to build up on your home’s exterior paint, concrete surfaces and window frames. This can cause irreversible damage, cracks, slippery conditions and damage to your siding and foundation. The rule of thumb is to check the weather forecast and avoid power washing in the winter season, especially before a coat before winter to protect your home.
3. If You Have Lead Paint
If your home was built before 1978 it may have coats of paint with lead-based materials. High pressure water from a power washer can release harmful lead particles into the air and soil and be a serious health risk. If you suspect lead paint consult a professional power washer for proper removal to get the job done safely.
4. When There Are Visible Cracks or Holes
If your home’s siding, brick house or stucco has cracks, broken windows or gaps power washing can force water into these openings. This moisture can cause mildew growth, organic growth and structural damage and require additional cleaning and costly repairs. Address these repairs before you start a cleaning plan to maintain your home’s curb appeal.
5. If Your Roof Needs Cleaning
Roofs should never be power washed especially those with asphalt shingles. The high pressure can strip away the protective granules and cause leaks and premature roof deterioration. Instead opt for soft washing or alternative cleaning methods to maintain curb appeal without the risk of property damage. A professional service can get your roof cleaned using the right methods without excessive pressure.
6. Before You Paint
Washing before painting is good practice but high pressure washing can leave too much moisture in the building materials. If not dried properly this can cause paint to bubble and peel. Always allow enough drying time before starting a cleaning plan for painting. Use a mild detergent to remove dirt build-up and prepare surfaces for paint.
7. If you have wooden decks or fencing not sealed
Unsealed wood is porous and can absorb too much water when power washed, warping, mould growth and rot. Before power washing wooden surfaces make sure they are sealed and use the right nozzle and decking pressure. Improper power washing can lead to costly repairs and damage to your outdoor furniture too. Hiring house washing services can prevent this kind of damage and get the job done thoroughly.
8. If you have electrical fixtures or exposed wiring nearby
Power washing near outdoor electrical fixtures, light fixtures, electrical outlets or exposed wiring can be dangerous. Water can seep into electrical components and cause short circuits, electrical failures or even electrocution hazards. Always follow safety guidelines when cleaning electrical components. For these sensitive areas, professional pressure cleaning can get the job done safely and effectively.

FAQ
How often should I power wash my house?
It depends on where you live and your environment. Annual power washing is usually enough, but if you live in a humid area or on a dirt road you may need to power wash more frequently to keep your exterior clean.
Can power washing damage my house’s exterior?
Yes, if done wrong. High-pressure washing with too much pressure can strip paint, crack siding or push water into gaps. Use the right pressure and a professional service for a good clean.
What’s the difference between power washing and soft washing?
Power washing uses high pressure water, soft washing uses a mild cleaning solution and low pressure water with special cleaning chemicals. Soft washing is good for delicate surfaces like roofs and painted exteriors.
