What needs cleaning?

What is soft wash house washing?

House washing in Reading starts with a simple idea. Siding, stucco and painted trim are not made to take hard spray. A soft wash uses low pressure and a cleaning solution to break down algae, mildew and dirt, and then a gentle rinse carries it away. The solution does most of the work, not the force of the water.

This is different from the pressure washing used on concrete. High pressure can bend vinyl, strip paint, chew into stucco and drive water behind siding, where it can sit in the wall. A soft wash keeps the water pressure close to what comes out of a garden hose, which is why it is the usual method for houses.

Before the wash, plants are wet down and covered where needed, and the crew checks windows, doors and outlets. After the cleaner has sat for a short time, the walls are rinsed from the top down.

What grows on houses in Reading, and why?

Reading has humid summers, plenty of shade and a lot of mature trees. Those conditions are ideal for green algae and mildew on the sides of a house. The north wall, the shaded back of a twin and the area beside a downspout are the usual trouble spots.

  • Green algae and mildew show up as green or gray patches on siding, trim and stucco.
  • Dirt and cobwebs collect under eaves and around lights.
  • Soot and grime darken older brick, especially in the city.
  • Efflorescence is a white, powdery mineral deposit that can appear on brick and masonry after moisture passes through it.

Chalky, faded vinyl is a different problem. That is sun wear on the plastic and it does not come off with washing. A crew should tell you that before the job.

Is soft washing safe for older homes and different siding types?

Soft washing works on vinyl, aluminum, fiber cement, painted wood, stucco and most brick. The details matter, especially with older Reading homes.

Many homes here were built before 1978, and older painted surfaces can have lead paint under newer coats. Flaking paint should be handled with care, so ask any contractor how they deal with it. Soft old mortar on brick rowhouses can crumble under hard spray, which is another reason to keep pressure low. Worn caulk, loose window seals and cracked trim can let water in, so a crew should point out weak spots before washing, not after.

Twin and rowhouse walls that you share with a neighbor are worth a word with that neighbor first, since runoff and overspray can reach their side. For the roof above the siding, see roof cleaning.

House washing is priced by the job. The main factors are:

  • The size of the house and the number of stories
  • The siding type, since stucco and heavily textured walls take longer
  • How much algae, mildew or staining there is
  • Access, such as tight side yards, steep ground or shrubs against the wall
  • Extras such as porches, trim, a detached garage or a fence

Ask for the scope in writing. A good quote should name the surfaces being washed and what the crew will do to protect plants and windows. If you are also thinking about the driveway, a combined quote for driveway cleaning may make sense.

How long does it take, and when should you call?

A typical house takes several hours, but size, height and the amount of growth all change that. Your written quote should give you an idea for your home. Plan for dry weather, since heavy rain stops the work, and for temperatures above freezing.

Call when you see green or gray patches on the siding, when the house looks dull next to the neighbors, or before painting, listing the home or hosting a big family event. Cleaning before painting also helps the new coat bond. Spring and early fall are common times, though a shaded north wall can be washed in any mild stretch.

Questions about pressure washing in Reading

What is the difference between soft washing and pressure washing a house?

Soft washing uses low pressure and a cleaning solution that kills algae and mildew at the source. Pressure washing relies on force. For siding, stucco and trim, the soft method lowers the risk of bent panels, stripped paint and water behind the walls. Concrete is different and can take more pressure.

Will soft washing damage my plants and landscaping?

It should not if the crew prepares properly. Plants are usually wet down first and covered where needed, and rinsed afterward. Tell the crew about any delicate plants, garden beds or a vegetable garden near the walls before the day of the job.

Can you clean stucco and painted brick?

Yes, with low pressure and care. Stucco can crack or chip under hard spray, and painted brick can lose paint. A crew should look at the condition of the surface first and tell you if anything looks too fragile to wash safely.

Do I need to move anything before the wash?

Move cars, grills, furniture and anything fragile away from the walls. Close all windows and doors, and let the crew know about outdoor outlets, lights or pets. A short walk around the house with the crew before they start can catch most problems.

How often should a house be washed in Reading?

It depends on shade, tree cover and how humid the summer was. Many shaded houses show growth again within a few seasons, while sunny walls may stay clean longer. If you see green patches coming back, it is time to look at the walls again.
