"Our project was actually a crawlspace encapsulation. We have a lake cabin that was built in the 1960's. It had a dirt floor in the crawlspace with bare block masonry foundation walls. It also had old, damp batt insulation that was falling down from the joist spaces. American Waterworks came in, removed the old insulation (a nasty job!), laid down a 2 layer moisture barrier system and spray foamed the foundation walls and rim joist area. I can't believe what a difference this has made to our air quality, much warmer floors. We used to have to wipe down the windows every morning during the winter because of condensation. Not any more! I would highly recommend this company if you have the same needs!!"

"Gregg and Gunnar did a fantastic job of lifting and sealing my garage floor. After 20 years of slowly failing, sinking, and cracking, they were able to get it back to an acceptable condition. It'll never be "flat" like freshly poured concrete but, it is so much better after their work. They took the time to explain the process and also any areas where they were unable to get the slab perfectly flat again, and they explained why. They were quick, cleaned up after themselves, and patiently explained the process and results"

"They were on time, they were friendly and explained what they were doing and the job was difficult and challenging and they returned to get it done. It was a 2 day project that turned into 3 and they even came to work on it on a Saturday."

Masonry FAQs, answered by experts

You can turn a red brick white through a process called whitewashing. Whitewash isn’t a stain but rather is made from water and white latex paint. Adding more water to the mix will make the solution look lighter when applied, and adding more paint will make it look more white.

A traditional rectangular brick that is used for siding, brick walks, and pathways is 8 inches long by 4 inches wide. If you are shopping for fire bricks, the standard dimension is typically 9 inches long by 4.5 inches wide.

Whether you’re installing brick siding over a traditionally-framed home or you’re using genuine brick construction to build, the biggest downside of a brick house is the higher cost you’ll pay for the materials and labor. Real brick construction also means your home build will take longer, as it’s more time-consuming to construct brick walls than it is to frame out your home.

On average, a quality exterior brick stain can last between 10 and 20 years, and sometimes even longer. While it will look its best for a minimum of three to five years, its total lifespan depends on several factors. These include the quality and type of stain used, the condition of the brick, and the thoroughness of the surface preparation, such as proper cleaning. Following the manufacturer's application instructions and applying a sealant as a final step is also crucial. The stain's longevity can be affected by your location, climate, and the brick's exposure to harsh weather, high traffic, and other elements. Over time, the stain may begin to fade or look dingy due to weathering, erosion, dirt, and debris. Compared to paint, brick stain generally has a longer lifespan.

Unfortunately, there are many disadvantages to stone houses. They are slow to build and the materials are pricey, both of which balloon the total cost. Stone walls require a more robust foundation, which costs more to install. Running plumbing, electrical, and HVAC through a stone house is much more difficult too, so homeowners need to seriously consider if the aesthetic benefit is worth the cost of building with stone. One of the questions to ask a masonry contractor is if a similar aesthetic can be achieved with another material.
