"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."

Foundation Repair questions, answered by experts

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

New constructions need time to “settle” and sometimes, small hairline cracks occur as a result. Larger horizontal or “stair step” cracks, however, are usually a sign of a deeper, more severe issue. It could indicate an issue with the soil beneath the home, a problem caused by an overgrown tree, or another problem.

Yes. Water can penetrate through a concrete foundation wall. This can happen whether or not you have cracks, as concrete is a porous material. You’ll want to take steps to waterproof your basement or crawl space.

Whether or not repairing your foundation is worth it before selling depends on the extent of the damage, the cost of the foundation repair, and your timeline for relocating. If the damage is major or structural in nature, chances are you’ll sell at a higher price if you take care of the problem beforehand. You should consider the cost of the repair first, though, as laying out thousands might not be possible with your budget. Additionally, if you’re in a rush to relocate, you might want to repair before selling so as not to limit your buyer pool.
