"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"

"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!!"

Masonry FAQs, answered by experts

Brick is the closest choice when seeking to capture the timeless look of stone with a more practical and budget-friendly option. When comparing stone versus brick siding, the price range of $200,000 to $400,000 for average brick home construction is dramatically lower compared to the cost of building a stone home. If you'd like to keep the stone aesthetic without the cost, stone veneer and manufactured stone are both less expensive than real stone.

Choosing the right paint color for your brick house can be a daunting task. A great strategy is to find painted brick houses that you like and try to replicate the look by researching their colors or asking the homeowners for the specific paint color code.

If you're looking for specific ideas, several colors work well on brick. Different shades of white, such as off-white or cream-white, can create a modern, timeless, and classic look that is unlikely to go out of style. For a more contemporary aesthetic, you might consider a matte black tone. Other popular choices include gray, blue, and sage green.

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.

Yes, it is essential to prime or seal a brick fireplace before painting. Brick is a porous and highly absorbent material, so without a primer, paint can seep into the surface, resulting in uneven coverage and allowing the natural brick color to show through. To avoid this, apply one or two coats of a masonry primer. The primer will seal the brick and provide a smooth, uniform layer for the paint to adhere to. Ensure the primer is completely dry before applying the topcoat of paint.

The exact cost of bricks depends on the type and size of the bricks you use for your project. Generally, standard clay bricks cost between $350 and $850 for a thousand bricks, or an average of $550. Brick veneer costs around the same for materials but is easier to install than solid bricks, so you’ll save on labor by choosing this option.
