"My sewage ejector pump in basement would not stop running and I was looking to replace it. I texted Dean two pictures of the pump, he was able to give me a quote over text and the price was quite reasonable. He received a new pump on 5/22/2023 and came over to my house. After opening up the old pump and checking, he told me that the only thing that is really broken is the check valve, the switch got stuck but is still functioning, and the pump itself works fine. I ended up asking him to only replace the check valve and the switch and this saved me about $1000 from the original plan. I appreciate Dean's honesty, professionalism, and a job well done."

"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 repairs FAQs
If foundation problems are not fixed, not only do repairs eventually become very costly, but it can lead to structural damage to the house above. Eventually, if the foundation problems are allowed to persist, the foundation walls can cave in or collapse. That’s after other issues like flooding and mold have likely been allowed to develop. Although not all cracks are structural problems, some can be and even if they start out small, they can develop into major problems. The earlier foundation problems are discovered and fixed, the lower the cost to repair will likely be.
Yes, foundation repairs are worth the cost at any stage to avoid a dangerous living condition. A failed foundation can lower the value of your home by up to 20%. Whether it’s the smallest problem like a thin crack less than ⅛-inch wide, a horizontal crack, a crack letting water flow through, or a wall bowing inward, repairing foundation problems as soon as possible is worth the cost. Sometimes a temporary fix can be applied until you have the budget to completely fix the problem, but the longer the problems persist, the more costly repairs may be.
The most common first signs of foundation issues include:
Cracks in the foundation walls that grow
Signs of moisture or water leaking through cracks in the foundation
Standing water in the basement
Sagging floors or walls
Cracked walls in upper floors
Doors and windows that don’t close properly anymore
Foundation repairs cost about $5,000, on average. Typically, prices range from $2,200 to $7,800, depending on the type and extent of repairs needed. Cost factors include foundation type, home size, soil stability, accessibility, and the ultimate cause of the problem and what methods and materials are required to fix it.
If you’re noticing signs of foundation issues, the first step to fixing a foundation problem is to hire a foundation repair inspector. They will determine the problem, the cause, and the severity before recommending a course of action to repair the foundation. The method for fixing foundation problems depends on the problem and what options are available. A few possible solutions include:
Epoxy injections
Mudjacking
Piers made of steel or concrete
Jacks
Hydraulic piers
Carbon or steel reinforcement strips
Waterproofing materials
