"The visit to my home in West Hartford was a nice affair. The technician explained everything. He even mentioned that I had to get a plumber to remove the sink away from the wall, so the work could be done to repair the window and wall area, but I did not hear him mention that I had to pull permits. The problem with this permit pulling issue is that I never initiated the pulling of permits, and this also is a red flag for me. The pulling of a permit should always be done by the contractor who is doing the job. It ensures that the permit pulled is to code. It ensures that the permit pulled follows local ordinance and CT. laws and statutes regarding construction, and that also includes consumer protection mandates in the State of Connecticut. Having me pull the permit to allow the CT. Basement Systems to do the work is a big, red flag, and it can result in my home owner's policy being cancelled if the permits are pulled either after the fact, or the permits pulled do not line up with the inspection process. I can also be fined by the town for pulling permits after the fact too. I've had my furnace replaced. The plumbing company who replaced the furnace followed state law and guidelines. Especially, since funding provided through a loan from a Credit Union chosen by the State of Connecticut ensured that permits were pulled correctly, legally. The same applies to my roof being replaced. The roofing company pulled the permit. Having a customer whom you are charging in excess of $20,000 to pull a permit is putting that customer in legal jeopardy, which is unacceptable. If I sell my house, and I had the work done in my basement, and the permits were pulled by me. The person who bought my house could sue me for an incorrectly pulled permit. How would I answer questions from the town about the technical aspects of the job, which should be handled by the contractor directly? Why introduce another layer of bureaucracy that slows down communication? Have the contractor pull the permit, so that the contractor and the municipality, town or city can communicate directly, and the pulling of the permit is done correctly and legally. How would I know, when the town should be doing an inspection during or while the job is being completed or after the job is completed? This should never be a requirement of the customer to pull the permit for a job to be done. The tech who visited my home mentioned that I had to hire a plumber to move a basement sink, but they did not mention about pulling of permits, but I went and re-read the quote again, and it is at the bottom of the quote page under "Customer Will" that states not only hiring of the plumber but also pulling permits and scheduling inspections. I did not have this job financed by CT. Basement Systems. I, instead, decided to get a home equity loan. If I did not get the home equity loan, then decided to go with CT. Basement Systems financing, then I would be screwed. The best thing I did was slow the process down, seek my own financing, and ask larger, bigger, deeper questions that prevented me from making a mistake by allowing this work to be done."

Basement Waterproofing questions, answered by experts

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Your homeowners insurance can cover slab leak repairs, but it really depends on your policy. Some homeowners insurance policies only cover slab leaks caused by natural disasters, while other plans are more comprehensive. You might also want to check your home warranty plan to see if they'll cover the cost of the repairs if one of your appliances caused the leak.

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.

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.
