"I had a great experience from start to finish. I had four different foundation companies look at the large crack in my foundation. Two said to put epoxy in it and I would be good. The third offered a slightly more involved fix that would not address the root of the problem. American Waterworks was different from the start. First of all, they book a three hour appointment so they can fully investigate, measure and explain exactly what is happening and what needs to be done to truly fix the problem. The level of knowledge and expertise shown by the the Design Specialist, Chuck, was astounding. He even predicted that there would be at least one if not two more cracks in the foundation we could not see and their location and he was right on both counts. I ended up needing 10 helical piers and 7 helical anchors to repair the foundation and stop it from rotating backwards toward the hill and to stabilize and lift the foundation back to its original position. The three man installation crew was incredible. Jose the Foreman, Luis the Co-Foreman, and Jose the Production Specialist were extremely hard working, knowledgeable and always willing to take time to answer any questions I had about the project. Their level of professionalism, courtesy and attention to detail put me at ease during such a major undertaking and I always knew my house was in good hands. I can not recommend American Waterworks enough to anyone needing their foundation repaired."

"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"

"I cannot say enough good things about Rich and his crew at Custom Craft Environmental. After having our sump get overwhelmed by 7+ inches of rain, we were lost. Made several calls to "national" water clean up companies with no reason. Rich was at our house 2 hrs after we called and his crew was there the next morning. They were efficient, helpful, knowledgeable, kind, punctual. Price was good and work was excellent. We highly, highly recommend."

Masonry FAQs, answered by experts

The material you use depends on how hard-wearing your steps need to be and what you want them to look like. The most common stone for exterior steps is bluestone. It’s hard-wearing and durable, and bluestone steps cost between $15 and $30 per linear foot. Limestone is also a popular option and is mid-range, costing $25 to $50 per linear foot. You should always consider the specific requirements of your project before ordering any materials.

If your old bricks are in decent condition and you have the space to store them where they’ll be protected from the elements, keeping old bricks is often worthwhile. You’d spend anywhere from $70 to a few hundred dollars to have them removed from your property, in which case you won’t be able to use them for future projects. Holding on to old bricks in good condition means you can use them later for other DIY projects, potentially saving yourself some money on disposal and new materials down the road.

A well-made brick wall can last up to 100 years if maintained properly, which includes regularly repairing the mortar every 30 to 50 years. If your brick wall is under 30 years old and is already showing signs of repair, it may be due to poor brickwork and installation. Extreme weather conditions can also accelerate a brick wall’s life span (especially the exterior of a house).

Most of the time, you don’t need to seal brickwork and can save that money for another area of home improvement. But if your brick is cracking or you live in an area with a lot of excess moisture (either in terms of rain or freezes), sealing can extend the lifetime of your home. But, make sure you use a breathable sealant, like siloxane, to allow the moisture to evaporate on its own.

Painted exterior brick does not usually need sealing. Brick is a porous material, so you don’t want to apply a sealant that could trap moisture inside the bricks and cause erosion and structural damage. The risk of moisture-induced damage after sealing is higher in colder climates where trapped moisture can expand if it freezes. On the other hand, it makes sense to seal really old brick or kitchen backsplashes, where moisture from cooking can weaken the brick.
