"I received a phone call from Forest Excavation within 1 hour of my request. They were very professional. The complaint I have is that home advisor contacted a professional no where close to the town I live in. I think if you are going to recommend professionals home advisor needs to correct how their location searches and apply what the person has entered for the demographic info."

"So I live in a older house (1947) so the plumbing is older too. Anytime I used my sink dishwasher or laundry the water would all but flood my basement making it almost unusable. I called and talked to Seth he was able to get to my home the next day and diagnose the problem my pipes in the concrete were old and clogged beyond repair well he managed to completely redo all of my plumbing brand new and have it up and running in a matter of a few hours! I now have a dry usable basement. He gave me a very decent price as well! Now hopefully I don't need another plumber anytime soon but if I do I'm calling seth at SWB!"

"I highly recommend Octagon Cleaning and Restoration. We recently purchased a house on the water and discovered that we had a mold issue in our basement. Matt and his crew were professional, informed us what needed to be done and completely eliminated the mold and the musty smell. Matt was very responsive to my texts, answered all my questions and a great representative of Octagon."

"Though Rob was extremely courteous and prompt, he quickly diagnosed that we would need to drill into the basement floor to create a sump basin to prevent further flooding, at a total cost of about $4500.00. Wanting a second opinion, I called my plumber. Within seconds of walking into our basement, he found that we already HAD a sump basin, and that an old house trap was clogged and causing backup to the basin. For $1000.00, the plumber removed the house trap and ran the line directly to the sewer, cleaned the sump basin, and we have not had an issue since. In the end, we saved thousands of dollars and a lot of unnecessary drilling which would not have fixed the issue. I do not think that Rob was being deceitful in any way, but I was disturbed that he did not find the existing basin which was under a large, loose tile in the utility room where we stood discussing the issue for 30 minutes. In my desperation to fix the problem, I very nearly did not get a second opinion; boy, am I glad I did!

"We got TWO (you see in pics one has green seat cover, the other purple) Kohler water saver 1.28gpf plug free toilets! I have special needs with my back and we got exactly what we wanted round bowl and standard height. He upgrades from glacier bay to awesome #1 Kohler us because of an initial miscommunication that we easily worked out. Yay! No more plugging AND water savings so they will pay for themselves within a year. Thank you Chuck. We will call your for our next plumbing job!"

Basement Waterproofing FAQs, answered by experts

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

Crawl space foundation problems can stem from a few different issues, but the most common are moisture and water problems and soil instability. Moisture and water issues are often a result of poor drainage, which can lead to water intrusion and soil expansion and contraction, leaving your foundation under added stress. A few things can cause soil instability, including poor drainage, karst landscapes and resulting sinkholes, and poorly compacted soil during construction.

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.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

Preventative measures, such as maintaining drainage systems, installing sump pumps, inspecting roofs regularly, and crafting comprehensive emergency plans, can help mitigate future risks.
