"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!"

"Nate communicated with me quickly when I posted my job to fix an outdoor spigot and replace a toilet. He had availability right away, but it turned out that I didn't need him for several weeks. He was able to do the job when I needed him at a very fair price, managed the job well & left things cleaner than he found them. His business is fairly new, but he is a Master Plumber with a lot of professional experience and a very nice guy. We all need a dependable plumber on call, and I've found mine. Hope you'll give him a call on your next job!"

"I have an old farm house. It is at Least 200 years old. It has a stone foundation. Every spring my cellar fills with water. I was given a quote in November on 2022. They installed the water proofing that December. They kept to quoted price with no surprises The crew kept to the schedule I was given. They were professional and left my cellar looking better than I have ever seen it With the soft winter and dry spring I was afraid that their work would not get a good test. However, last night We got four to five inches of rain. In the past this would at least left a foot of water in my cellar. Today it is bone dry. Basement Improvement is a local family run business that I would highly recommend to anyone."

Basement Waterproofing FAQs, answered by experts

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.

The most cost-effective foundation repair is using masonry patches and sealants to seal foundation cracks and offer some support to prevent further damage. These methods are used to fix minor foundation cracks quickly. However, they’re not suitable as a long-term solution, and they only offer minimal stability. On average, masonry patches and sealants cost $500, but a sealant like an epoxy crack injection can total over $2,000. If you’re handy and only looking for a temporary solution until you contact a local foundation repair contractor for a more permanent one, you can save hundreds by DIYing this repair.

You should always hire a structural engineer or a professional and licensed foundation repair company for crawl space repair. These professionals will often be able to treat the symptoms of the issue as well as the underlying problem so that you don’t have ongoing damage. They’ll also often take preventative measures to stop the issue from recurring in the future.

Regular inspections, maintaining proper grading around the foundation, and keeping gutters clear are advisable. Vapor barriers and sealants may need checking for wear after several years.
