House Washing Services in Dover, MA

Cedar shake, stone and slate cleaned at hose pressure — with a written scope before anyone touches the property.

Free Estimate

A Dover property is rarely one building. There is the house, and then there is the barn, the pool house, the carriage house, the fencing and a few hundred feet of stone wall. Most of it sits under old-growth oak, and most of it has never been cleaned properly. We soft wash the entire property — biodegradable solution at low pressure, enough dwell time to kill what is actually growing, then a controlled rinse. Cedar shake, aged stone and slate come through it unchanged.

Why Dover Exteriors Need a Gentler Method

The tree cover that makes Dover beautiful is what makes the growth stubborn.

Old-growth canopy over the roofline drops sap, tannin and leaf litter that stain shake and shingle
Lichen, not just algae — Dover roofs and north walls sit shaded enough for lichen to root into the surface, and it does not rinse off
Cedar shake is unforgiving — once a pressure washer raises the fibres, the shake is permanently furred and no longer sheds water properly
Soft mortar and aged stone lose their joints under high pressure
Wells and septic on nearly every parcel — where the water goes matters as much as what we spray

The machine is not what cleans a Dover house. The solution and the dwell time are.

Benefits of House Washing in Dover

On a property this size, washing is asset maintenance.

Stops Lichen Before It Costs You a Roof Lichen holds moisture against shingle and shake. Left long enough, the conversation stops being about cleaning and starts being about replacement.
Preserves Cedar Shake You Cannot Easily Replace
Matching weathered shake is difficult and expensive. Keeping it clean is neither.
Brings the Whole Property Up Together
A spotless house beside a green barn reads as neglect. Doing both is what makes the place look maintained.
Protects Paint and Stain Through the Winter
Growth left on a painted or stained surface through a New England freeze breaks the film from underneath.
Gets the Surface Ready for Painters or Stainers
Anyone quoting a finish on your house will want it washed first. Doing it properly saves the redo.

How We Work

A proper walkthrough
We map every structure and note materials and problem areas before quoting. On an estate property this is worth doing in person.
A written scope
You get it building by building, surface by surface. Nothing appears on the invoice that was not on the quote.
Protection first
Plantings covered and pre-soaked. Wells and leach fields identified, with runoff routed clear of both.
Soft wash throughout
Low pressure on shake, clapboard and roofing. Higher pressure only on hard surfaces where it is safe.
A final walk, structure by structure
We do not leave until you have seen each one.

Frequently Asked Questions

Will soft washing damage cedar shake?

No — it is the correct method for shake. High pressure is what ruins it, raising the grain and stripping the natural oils. We never put a pressure washer on cedar.

My roof has green lichen, not just black streaks. Can that be removed?

Yes. Lichen roots into the surface and needs the right solution with proper dwell time. It dies off and weathers away over the following weeks. We do not scrape it or blast it.

We are on a well and septic. Does that change anything?

It changes how we work, not whether we can. Products are biodegradable and applied at low volume, and runoff is directed away from the wellhead and leach field. Show us where they are at the walkthrough.

Can the barn and fencing be done in the same visit?

Yes, and it costs less than a separate trip. Outbuildings weather faster than the house and are usually the first thing that looks tired.

Can you send proof of insurance?

Yes. Ask and the certificate goes out the same day. We send it before scheduling on estate properties as a matter of course.

Do we need to be home?

No. We need outside water access and gate codes if the property is secured. Most of our Dover clients are not on site while we work.

What other towns do you cover nearby?

Sherborn, Needham, Wellesley, Natick, Westwood and Medfield, among others.
