"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!"

"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!"

"They messed up the ceiling part in a corner.  They got the wall paint mixed in with the ceiling paint.  They did try to fix it.  We do have cathedral ceilings.  It took them a long time to paint.  I was a little frustrated or upset by the fact that the painter didn't have an extension ladder and ended up standing on my wood stove to reach.  It made me so nervous.  I really didn't want them to come back to fix the ceiling.  They did smudge it pretty bad, but I just choose to not look at it. It wasn't exactly what I would have expected from a professional painter, but they did an okay job. They were very responsive.  The owner called me the next day to see how it went.  They were very punctual and professional.  I guess it would be somewhat shady with the lack of ladders they had.  I would probably use them again.  Because of the difficult job, I think overall they probably are decent painters, it was just above their expectations.  They were prompt and worked right thru until they were done."

"I hired him for a home inspection, a radon air test, and a septic inspection. He arrived within 10 min of appointment time. His home inspection was very thorough and a comprehensive report provided in a timely manner. His radon air test was completed in the basement, rather than the lowest living area (stated that there was a laundry hookup in the basement so it had to do down there, despite a full laundry room on the second floor)"

Basement Waterproofing FAQs, answered by experts

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.

Basements with persistent moisture problems or flooding shouldn’t be finished until the moisture issues have been fixed. In addition, if your foundation is cracked, you have unmitigated radon levels, or you have asbestos or lead pipes, remediate the underlying problem before finishing your basement. Turning a basement into living space before fixing these issues can lead to serious health risks or structural damage. 

In most climates, contractors recommend closing your crawl space vents in winter. Keeping them shut protects your crawl space from freezing temperatures, pests, and cool breezes that can lead to chilly floors in your home. However, it's often best to speak with a local crawl space team about your specific design and its relationship to the winter season.

It depends on what caused your basement flooding, the extent of the problem, and the risk of the flood continuing. If your flood is coming from a septic system or sewer line, breathing in the sewer gasses can be dangerous, so you should vacate. If the flood occurs from an ongoing natural disaster, relocating to a safe area might be wise. If you just have a plumbing leak or rainwater coming in, you can likely stay in the house if you don’t have electrical lines down there, but make sure you call in professionals to fix the issue immediately.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.
