MUTUAL MATERIALS COMPANY 

Our story begins with the 

Great Seattle Fire of 1889 

that destroyed over 30 

acres of the downtown 

business district. The only 

building left standing after 

the fi re was built with 

brick. Before the smoke 

cleared, a city ordinance 

was passed declaring that 

all buildings and sidewalks 

in Seattle had to be made 

of fi reproof materials. 

Workers from all over 

the United States came 

to Seattle to help rebuild, 

including Daniel Houlahan, 

a bricklayer from 

California. And, in 1900 he 

went on to found Builders 

Brick Company, Mutual 

Materials’ predecessor. 

Over the past century, 

Mutual Materials has grown 

to be the Northwest’s 

leading manufacturer and 

distributor of masonry and 

hardscape products. As we 

enter our next century, 

we are more aware than ever 

of the responsibility we have to 

maintain our natural resources. 

In keeping with the Northwest's 

leadership in green building, we

WHY BRICK? 

Choosing the right siding for your home is a decision with lasting impact. 

You want your home to have curb appeal, style, personality, and 

longevity. Brick is the only siding choice that offers you 

all of these benefi ts in one. 

STYLE 

Brick is multi-dimensional. Unlike stucco or 

siding, brick allows you to achieve virtually 

any architectural design through a variety of 

complementary shapes, colors and textures. 

Whether you are building a new house or 

remodeling your existing home, brick options 

range from full veneer, to creative details that 

show-off your personal style, to accents such as 

arches and quions. 

QUALITY 

Quality is something that each of us innately 

understands. We might not be able to defi ne it, 

but we know it when we see it. Your home tells 

the world who you are and what you value. With 

thousands of years of proven performance, 

building with brick is building for generations. 

MAINTENANCE SAVINGS 

Brick never needs painting or sanding. Brick won’t 

rot, fade, peel, or dent. In fact, brick actually 

improves with age. Think of the time, energy and 

money you save never painting again. 

ENERGY CONSERVATION 

As a natural insulator, brick is slow to absorb or 

lose heat. You’ll be warm in the winter and cool in 

the summer, all while saving money on fuel bills. 

FIRE RESISTANCE 

Made from clay fi red at nearly 2,000°F, brick is 

the most fi re resistant siding material available. 

Because of this feature, many insurance 

companies offer reduced rates for brick homes. 

RESALE VALUE 

According to Marshall & Swift’s Residential Cost 

Handbook, if and when you decide to sell your brick 

home, it will command a higher price, making your 

initial investment a very wise one indeed.

VENEER 

Craftsman, Tudor, cottage, 

contemporary —brick is all of these. 

Whether you want to build a home entirely of 

brick, or add drama with accent elevations 

or wainscoting, brick is an excellent choice. 

Used alone or in combination with another 

material, brick’s range of color and texture 

options will make your vision a reality. 

Ebony and Red Varitone Cedar Creek 

INTERIOR 

Brick brings a feeling of hospitality and 

warmth to interior spaces. Adding brick to 

an accent wall, fi replace, kitchen, or wine 

cellar turns ordinary spaces into works of 

art. Whether your fi replace is wood burning 

or natural gas, brick is not only aesthetic 

but a functional material. 


DETAILS 

Brick details around windows and doors 

enhance a home’s look. Use simple headers 

and sills to balance an elaborate design, or 

include arches and keystones to add subtle 

design elements.

Columbia Red

OUTDOOR 

FEATURES 

To extend the architectural design beyond 

the four walls of your home, use brick on 

fencing, pillars, lampposts, planters, and 

entries. It will withstand the elements, 

never rotting, fading, or peeling.

How do I contact Mutual Materials? 

You may visit one of our 17 area branches (locations noted on back), or 

call our Customer Service line at 1-888-MUTUALØ (688-8250). 

Where can I purchase Mutual Materials ® Products? 

Mutual Materials ® products are available through our 17 branch 

locations. Our products can also be found at building material retailers 

and lumberyards throughout the United States and Canada. 

Visit www.mutualmaterials.com to fi nd a location near you. 

Can I install my own project? 

Yes. However, we recommend hiring a qualifi ed mason for more diffi cult 

projects such as veneer, architectural details, tall structures, and 

fi replaces. 

Does Mutual Materials offer installation services? 

No. But we can recommend a number of qualifi ed masons. Please call 

our customer service line and we will gladly refer you to several longstanding 

masons in your area. We encourage you to bid your project 

with several contractors and check with the State to verify a contractor’s 

license and bond. 

How do I clean the new masonry I installed? 

For brick, natural stone and Robinson Rock , Mutual Materials sells a 

variety of cleaners developed to remove latent mortar from masonry 

surfaces. Mutual Materials customer service can recommend the right 

cleaner for your project. Follow directions on label for best results. 

Cultured Stone ® should not be cleaned with any materials containing 

acids. For best results, carefully clean as you go and dry brush excess 

mortar before it sets. 

Should I apply a water repellent to my new masonry project? 

Masonry exposed to weather should receive a water repellent coating 

once the masonry is cured (usually 28 days). This will help keep your 

masonry looking new. Mutual Materials can recommend the right water 

repellent for your project. Avoid any sealers that contain acrylics. 

What type of maintenance do masonry products require? 

Brick, natural stone, Cultured Stone ® , and Robinson Rock require very 

little maintenance. Occasional brushing or hose rinsing should suffi ce. 

Avoid the use of any acidic materials, as they may damage masonry. 

Please do not pressure wash Cultured Stone ® , as you risk voiding the 

warranty. To avoid impacting the color of the stone, Owens Corning ® also 

warns against the use of dust removal products (Endust ). 

COMMON QUESTIONS 

WE HAVE THE ANSWERS 

What is the white fi lm on my masonry / natural stone, and will 

it go away? 

The white deposit you see is called efflorescence. There is no need 

to be concerned that your product is damaged or defective, and 

it has no adverse effect on the physical structure of the product. 

Efflorescence is normal on clay and concrete masonry, as well as 

on some natural stone. It may appear on the surface of new and 

older projects alike, and is a naturally occurring phenomenon. It 

occurs with leaching of salts that are deposited on the surface 

when water evaporates. Efflorescence can correct itself over 

time and exposure to the elements. It can also be cleaned with a 

number of commercial cleaners. However, we recommend that you 

discuss cleaning options with your contractor or a Mutual Materials 

customer service representative before attempting to clean 

efflorescence. 

Can masonry products be used to remodel my 

existing home? 

Yes. Masonry products are excellent for home makeovers. Cultured 

Stone ® and Robinson Rock can be installed without the need for 

supporting foundation. Brick and natural stone will require additional 

support from either a below-grade footing or an attached steel angle. 

What is the difference between Natural Stone and 

Cultured Stone ® ? 

Natural stone, as its name implies, is made by nature and cut at quarries. 

Cultured Stone ® is cast in molds taken from carefully prepared natural 

stone. Each color and texture uses its own blend of portland cement, 

lightweight natural aggregates and iron oxide pigments. 

What is the difference between Robinson Rock and 

Mutual Materials ® natural stone? 

Robinson Rock is natural stone that has been cut into thin pieces 

allowing it to be installed without a supporting foundation. Our natural 

stone comes in a variety of shapes, sizes and colors and averages 

3" to 5" thick.
