External property cleaning FAQs

Your commercial exterior cleaning questions: answered. 

Regular external cleaning can help maintain your property, improve its appearance and reduce walkway slip hazards.

But cleaning the exterior of your property can come with a host of unknowns.

As experienced providers of external cleaning services to businesses across Devon, the experts at ServiceMaster Clean Devon told us some of the frequently asked questions they hear about exterior cleaning.

  1. What types of surfaces can be cleaned with a pressure washer?

Pressure washers are an effective way to deep clean external surfaces where algae, mould and mildew might build up.

The following exterior areas will benefit from cleaning with a pressure washer:

  • Decking and patio areas
  • Driveways and walkways
  • Roofing and siding
  • Concrete and brick

However, some outdoor surfaces require more care and aren’t suitable for cleaning with a pressure washer. These include:

  • Asphalt shingles
  • Stained wood
  • Lead paint
  • Windows
  • Old mortar
  • Gutters
  1. How often should I have my property pressure washed?

For the majority of surfaces, an annual power washing should suffice.

However, high-traffic areas such as walkways, exterior entrances and car parks might need cleaning more frequently.

This will limit the build-up of dirt and vegetation, which could create a hazard.

  1. Can pressure washing damage my property?

Pressure washers use extremely high-pressure jet streams.

These can cause irreversible damage if incorrectly used or used on unsuitable surfaces.

Therefore, utilising a trained and experienced team is essential when pressure washing your property.

  1. What is the best way to clean gutters?

A gutter vacuum is the best way to clean your gutters.

It sucks up all the debris in the gutter without leaving any mess.

It is also much more effective than other techniques, like cleaning by hand.

  1. When is the best time to clean gutters?

The best time to clean your gutters is after autumn when gutters have become clogged up with falling leaves.

Or at the beginning of spring, when seedlings may take root.

  1. How often should I have my gutters cleaned?

Regular gutter clearing will stop gutters from becoming blocked and causing water damage.

Most properties require an annual gutter clearance, but those with nearby trees should have a twice-yearly clean.

Any gutters overflowing or allowing water ingress into your property will require immediate cleaning.

  1. Why use purified water for window cleaning?

Using purified water to clean windows leaves a completely crystal-clear finish.

Unlike tap water, which can leave impurities on the glass as the water dries.

Instead, purified water evaporates, leaving a clean, spot and streak-free surface.

  1. How often should I clean my windows?

The frequency of your window cleaning will depend on the nature of your business and its location.

For example, the windows of an office building on a busy road will dirty quicker than one on an out-of-town business park.

Generally speaking, properties that have high footfall (a shop or restaurant, for example) or provide healthcare (such as a hospital) will probably need window cleaning once or twice a month.

On the other hand, an office building will probably only need a six-monthly window cleaning.
