They came out for a foundation repair, before the repair they came for an inspection that was free. This is infact an excellent company to work with. The work was done on time and our foundation is now solid and I would highly recommend.
We had an unpermitted sunroom that was improperly supported. Darren was very professional, knowledgeable, and responsive. Ignacio did the work for the project, and he is extremely good at what he does and a very hard worker. I am very happy that at least one of our walls is properly supported by a concrete foundation and our sunroom is properly supported from below.
We got multiple estimates for foundation repair, and this company stood out because they actually took time to educate us on the problem. No pressure, no scare tactics, just straightforward advice and quality work. The repairs were completed faster than expected.
I was nervous buying an older home because of potential foundation issues. Their inspection was incredibly thorough; they used a laser level to document everything and provided a detailed, honest report with no pressure to upsell. It confirmed the house was solid and made me a confident homeowner.
I contacted them for a second opinion after another contractor gave me an extremely expensive estimate. They performed a full foundation inspection and recommended a much more reasonable solution. I’m very happy with both the service and the results.

We hired them for foundation repair after noticing cracks running across our interior walls. The crew arrived on time every day and kept the work area organized. The cracks have stopped spreading and the floors feel level again.
Had these guys over at my mom's for a crawl space repair. Cordination was top notch and they mad sure to excute and complete the job as agreed.
They repaired cracks in my foundation quickly and ensured everything was stable and secure before leaving. The staff was friendly, punctual, and very detail-oriented. I would definitely use their services again.
With homes fronted by the waters in Alameda all the way to the hillside streets in Orinda and near landmarks like Broadway Plaza and the Lesher Center for the Arts in Walnut Creek, the East Bay homes are exposed to a combination of climatic conditions, such as cold marine air, winter and dry summers. The states of the crawl spaces render them particularly susceptible to humidity, drafts and heat loss. In the long run, that does not only erode your foundation, but also increases your energy bills.
Our crew offers full crawl space repair and encapsulation to the homes in the East Bay to ensure they stay comfortable, energy-saving and structurally sound. Sealing, insulating, and vapor barriers are some of the services that we specialize in to avoid the entry of moisture, enhance temperature control and lowering heating and cooling expenses throughout the year.

By hiring us, you are not only buying a contractor, but a team that is interested in the comfort and performance of your home.
Most of the homeowners are unaware of the amount of energy they lose through their crawl space. The following are the most typical problems that we identify during the inspections across the East Bay:
Leaks in the air enable the conditioned air to escape and adding more use of HVAC and energy expenses.
Floored or poorly installed insulation permits the exchange of heat between floors and air on crawl space.
Spores of air that gets in through the ground cool the floors and increase humidity in the house.
We get to find the solutions to these issues at their initial stages, and this way we enable the homeowners to reclaim their indoor comfort and minimize unnecessary energy expenses.
A well-insulated crawl space is able to produce a more stable interior climate. Without insulation or insulated areas, cold air finds its way through the floor and heating becomes ineffective as well as the room temperatures become unevenly distributed across your house.
Our insulations are moisture-resistant and of high quality, which are designed specifically to insulate crawl spaces. Our insulation techniques are in concert with encapsulation systems to ensure that your floors are warm, limit drafts and prevent your foundation to be damaged due to condensation.
Floors tend to be drafty, which is usually caused by the fact that your crawl space is not sealed correctly. There are holes, fractures, and open vents that can support free movement of outside air under your house making your HVAC to strain more.
In sealing, we use professional grade materials and insulation barriers to seal each opening in our sealing procedure. No matter whether you live in Oakland, Fremont, or Walnut Creek you can find our team which will make sure that your crawl space is airtight, efficient in energy use and comfortable throughout the whole year.
We will assess your crawl space, discuss optimal encapsulation and insulation solutions, and do repairs that will produce long-term outcomes.
