"I have a mid century home with a concrete floor. I had multiple settling points and voids underneath the team at saber got it stabilized and leveled in a matter of hours. They were prompt, kept everything clean, and did everything I was expecting and hoping for."

"I bought the Big Deal which was just for a single top coat to reseal the deck surface.  However, my deck was in a little bit worse shape than the deal allowed.  However, Ryan was awesome and added in sanding and then did the reseal for no additional charge.  The surface is not perfect but that is due to the rough pre-condition it was in and not his fault.  Shortly after the reseal the deck drains started leaking in to the garage below.  Ryan and crew came out again to fix the drain at no additional cost.  Again, this was not in the deal I bought but they provide such great customer service.  I would definitely use them again and will recommend them to friends and neighbors!

"I recently hired JP Plumbing to address a clogged main line drain and the experience was exceptional. John (JP), the technician, provided outstanding service from start to finish. He was punctual, arriving right on time and ready to tackle the issue. John’s honesty and transparency really stood out. He took the time to explain the problem in detail and even went the extra mile by attaching a camera to inspect the pipes. He showed me exactly where the issues were occurring, giving me peace of mind and confidence in the work he was doing. What truly impressed me was his dedication to going above and beyond. Not only did he resolve the clog efficiently, but he also provided helpful maintenance tips to prevent future issues and keep my drains running smoothly. If you’re looking for a professional who truly cares about quality and customer satisfaction, I can’t recommend John (JP) and JP Plumbing enough. This is the kind of service everyone hopes for when hiring a plumber—professional, thorough, and completely trustworthy."

Basement Waterproofing FAQs, answered by experts

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.

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.

Water that pools under pavers can erode the soil foundation and weaken the paver structure. In some situations, it can also cause mold and mildew growth. If that happens, you may need to start budgeting for the cost to build and install a patio to replace the damaged one.

In some circumstances, foundation refacing or repair may be a better option for your home than sealing a foundation. It’s always a good idea to take steps to prevent moisture problems in your foundation, but if there are any structural concerns, those will usually need to be fixed first. When dealing with foundation issues, it’s a good idea to get a professional opinion so you can avoid bigger problems down the road. 

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
