    "This website wont let me specify what was actually done - it was far more than an inspection. The crew jackhammered out a section of basement floor, installed a drain pipe and sump pump, special channel and a kind of vinyl wall covering to direct any wall seepage to the drain and then the sump pump. They had to install a discharge line and connect it with my exterior downspout drain system. I am not a perfectionist, but I have very high standards. I learned not to take the lowest bid, but go with the company that most seemed to know what they were doing, had great reviews, and weren't trying to talk me into more than I needed. I was 100% completely satisfied with Upfront Construction. They are reliable, trustworthy, and do excellent work. Zezar was so smart and really knew his stuff; inspected the job, taught me the pros and cons of various choices, and was in regular contact with the crew, even coming back to consult with the crew so the discharge line connected to the exterior drain line seamlessly. The crew headed by Lucas, and ably assisted by Joe and Gus were outstanding. Professional, hard working, genuinely pleasant to interact with, and left the house spotless every day of a three day job. Last but not least, Melinda was excellent in her communications, paperwork, all that, which I truly appreciated, it isn't always like that. I highly recommend Upfront Construction, they can do many more things than the work I needed done, and I plan on hiring them again as I continue [slowly] renovating a 97 year old house. The best!"

    "I was referred to Ybarra by a friend who had their kitchen done. I was in love with the cabinets and the end result of it all and asked her who her contractor was. Ryan and Levi were so helpful and catered to my specific requests and time frames because I work a night job. Their crew went above and beyond, replied to my late-night text messages and the concerns I had about my dogs getting out while they were working. They made sure to clean and lock up every time they left and were very courteous about trying to keep the noise down while I slept, which was very nice of them as well. I couldn't be more pleased with the outcome of it all!! Highly recommend Ybarra Professionals!"

    "Jason responded quickly to come to our home and discuss building a retaining wall on a sloped dirt area which also required removal of 2 trees. He offered great suggestions while he was there and provided a competitive verbal estimate on the spot. He then supported his verbal estimate with a written quote within a few hours. Jason arrived with his crew the following week to begin the project. The weather caused many delays over the next several weeks but they made progress whenever they could. Jason was very good at keeping me informed with text messages. The completed project is perfect for what I told Jason I needed. He and his crew did an excellent job and I won’t hesitate to recommend J&K for any type of similar construction projects."

    "After I called Masonry Waterproofing Byron came out to assess the problem. He saw immediately that moisture was coming through the concrete block wall of my work area and said that the outside of the wall needed to be dug up so that it could be sealed and have a vapor barrier installed. At that time he gave me a ballpark figure as I was having two other companies coming to look at the situation. I elected to go with Byron as he seemed to know best what needed to be done. He indicated that it could take up to 5 or 6 days, so we scheduled it to start the following Thursday morning. The crew, Andy, Michael and John arrived a little before 8:30 on the first day. They spread tarps around the area to hold the dirt as they dug (by hand). The wall was 35 linear feet and dug to a depth from 4 to 6 feet. They were very polite and professional. They worked together as a team and each one knew exactly what he was to do. The second day they applied three coats of sealer, applied the vapor lock and back-filled. Byron was able to send in some additional workers to help speed up the job. On the third day, with a crew of 5 or 6 people, they finished up with the French drain. They cleaned up the area each day and at the end of the project left the site spotless. It is my opinion that if you want quality work done professionally, you need to check with Masonry Waterproofing and Drainage Masters."

Frequently Asked Questions

Where is a foundation in a house?

+

A house’s foundation is always located under the house itself. A foundation is the load-bearing portion of a home and is usually built below ground, though different types are built at different locations under a home. For instance, a basement foundation is built at least eight feet deep into the ground under the house to create living space below the ground level of the home. A crawl space foundation is built under a shallow trench beneath your home—typically between two and five feet deep. A slab foundation, also known as a monolithic or monoslab foundation, simply lays flat against the ground under your home. Pier and beam foundations also rest on the ground, but elevate the home using piers, typically about two feet off the ground.

What are the types of foundations for homes?

+
  • Basement Foundations: Also called a full basement foundation or a daylight basement, a basement foundation is one of the most popular types of foundations. One of the appeals of a basement foundation is that it offers additional living space under the home. A daylight basement typically includes windows to let natural light into the space. This type of foundation allows for homeowners to maximize the footprint of their home by offering a finished living space.
  • Concrete Slab Foundations: Also called a slab, monolithic, or monoslab foundation, this type of foundation is essentially a poured concrete slab that rests on the ground under your home. It’s typically one single piece and is relatively easy and inexpensive to build.
  • Crawlspace Foundations: This type of foundation provides just enough space under a home for a person to crawl around in to access plumbing or wiring, or store equipment such as a furnace.
  • Wood Foundations: These types of foundations are less common, though they were a popular choice in the mid 20th-Century. A wood foundation is typically made of pest and mold-resistant wood, like cedar or redwood. They are easy to install, though they aren’t as long-lasting as concrete foundations. Wood foundations are not ideal for climates that see a lot of rain and snow, as they must be built on very dry soil.
  • Pier and Beam Foundations: These foundations, which are common in coastal areas, use piers and beams to lift a house off the ground. Also known as pier and post or pier and pile foundations, the aim of pier and beam foundations is to support a home that is built on sand or soil that is prone to flooding, erosion, or ground shifts. A structural engineer needs to oversee the building of a pier and beam foundation to ensure its structural integrity.

How much does a foundation repair cost?

+

The typical cost to repair a foundation is between $2,200 and $7,500, though most homeowners pay around $4,800. The price of a foundation repair depends on the extent of damage. Major repairs that require the use of hydraulic piers can cost $10,000 or more, while minor cracks can run as low as $500. Fixing a leaky foundation by sealing it costs between $2,300 and $7,300.

What is the strongest foundation for a house?

+

Concrete foundations that are reinforced with steel plinth and beams are considered to be the strongest type of foundation—especially on lots with loose or muddy soil. This type of foundation uses a reinforced concrete beam built between the wall and the foundation. Homes built in areas that are prone to flooding or earthquakes also benefit from a foundation that contains steel plinth and beams.
