"The end result is very good, however, there were some challenges along the way, which at the time were annoying, but were really just part of any construction / repair project. The crew arrived on time to begin the process of hand digging and using an auger to drill the piers to a depth of 10-12 ft. The first challenge occurred when the auger broke our water supply line to the house and filled it up with water. Brown immediately called their plumbing company for repair, but the pouring of the piers was delayed. At he same time, the auger machine damaged our porch column and gutter downspout. The machine also damaged the siding corner at our sun room at the rear of the house. During the process of digging / drilling the piers our sprinkler system piping and control wiring was disturbed and / or damaged as well. The piers were successfully poured, and after curing, the foundation was successfully raised. Because we had a sewer leak to repair at the same time, we raised the foundation, had the leak repaired, and then Brown returned to perform the mudjacking. Here is where the ball was dropped a bit. During this process, there was an enormous amount of dirt / debris generated. This dirt was piled, on plastic on our front lawn and other places. We knew this going in. However, after the piers were drilled and poured, the mudjacking performed, there was a 2 week period in which there was absolutely nothing done to "finish" the job by filling holes, replacing landscaping, and grading the dirt around the house. Finally, they had a crew available to return, but by this time, in the June-July, with no sprinkler system, and huge pile of dirt on the lawn, well, it was a disaster.
To their credit, through all of these challenges, in the end they stepped up and made it right. They replaced the st Augustine in the front, their plumbers repaired the damaged lines, the price was adjusted to reflect the repairs to the downspout and siding, and they sent their sprinkler people out twice to repair / replace components damaged during the process.
During the whole process, everyone was responsive, kind, and professional.
All of our doors open and close now and we will have cosmetic repairs done in approximately 6 mos. after everything has settled.
Bottom line, we would recommend Brown Foundation Repair.

"We had an issue with our sidewalk and curb in front of our house being unlevel and possibly a safety hazard. Jakalon was a one man show last Saturday. He was courteous, informative and professionally personable when he spoke with my husband and I. We would check on him and his work during the process and he would stop and share what he was doing. We were able to sign off on his work in a satisfactory time frame. Thanks J, we like your work!"

"Installed a drainage system to deal with surface water issue. The day after completion we had torrential rain for 24 hours and it drained away completely. Installation was completed in 2 days with little disruption. I'm very happy with the service the team provided."

"The blockage was successful unstopped, but the oil and grease was left all over my driveway and my flowerbeds were a mess. It was way too expensive for a mess to be made of this magnitude. It was nearly 400.00 dollars for less than 30 minutes work. I was left to clean up the mess. This just wasn’t right."

Basement Waterproofing FAQs, answered by experts

No, you don’t want your crawl space to be wet because water and even moisture in the air under your home can attract insects and rodents, decrease your indoor air quality, increase your energy bills, promote mold growth, and even lead to structural damage. If you notice any signs of water or humidity in your crawl space, you should get the issues addressed immediately by contacting a professional. They can remove moisture and will know how to waterproof your basement to prevent ongoing problems.

Yes, slab leaks are fairly common, especially in older homes and places that are prone to earthquakes which can move home foundations.

It’s not the number of weep holes that should be of concern to builders but rather their spacing. Weep holes are usually spaced anywhere between 16 inches on center when using round tubes or wicking materials and 24 inches on center when using open-head joints. This is a more conservative spacing than the 33-inch maximum spacing on center that’s mentioned in the International Residential Code. All in all, the total number of weep holes a brick exterior should have will depend on the size of the structure.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.

Whether to waterproof your basement from the interior or exterior depends on several factors, including your budget.

Exterior waterproofing is generally considered the superior method because it stops water at the source, preventing it from seeping into and damaging your basement walls. This approach offers the most protection, making it ideal if you use your basement for storage.

By contrast, interior waterproofing is often less expensive and requires less labor because the area is more accessible.

For maximum protection against water leakage and moisture, applying waterproofing measures to both the inside and outside is the best solution. However, if you must choose only one, stopping water from the outside is the most effective approach to preserve your foundation and prevent damage.
