"We just had American Dry Basement install a waterproofing system in our basement. We've had issues with water in our basement and needed a total solution so we can sleep at night and go away without worrying about flooding. Steve T from American Dry came to our house and presented us with what the solution will look like and thoroughly explained the entire process. He also answered all our questions and was always available to talk to. He is extremely knowledgeable and an excellent professional to work with. Then Wilson and his two-man crew came to do the work and they were all professional, extremely hard working and respectful of our home. They always started early and worked all day long to get the job completed. They wrapped up all items that were still exposed after we cleaned out most of our basement, used vacuums and filters to minimize all the dust and left our basement cleaner than it was before. We highly recommend American Dry Basement Systems and we're so happy we chose them over the others we received estimates from. And their price was more than competitive for what we believe is a much better solution."

"The work went quickly and professionally.  The crew was careful to
protect our environment and to keep us notified of what they were doing
and when to expect noise, etc.  This was especially important as we have
 three older dogs and we were able to schedule their water theraphy for
the noisiest day. There was an additional problem discovered with
plumbing into the basement.  A pipe from the street to the water meter
had to be replaced by another contractor.  The Basement Guys were unable
to waterproof that spot until after the repair was completed.  They
returned promptly and completed the work, also double checking for any
chips or gaps that had arisen in the foam insulation and fixing them 
and touching up the waterproofing epoxy where the termite company had
drilled holes in the basement wall.  We were extremely pleased with
their service. They are phenomenal!We highly recommend Dry-X Waterprofing.

"I am writing this review to acknowledge the power of Angie?s
list as well as to express my satisfaction with the work done by M & M
Construction at my home in Hartford.  We
have a 100 year old house which one rainy day flooded in the basement ? the first
time this had happened in the 15 years we have owned the house.  The flooding was not rainwater, it was backed
up sewage!!!  We had a local plumber,
suggested by friends, check it out as an emergency and after hours and hours of
expensive manipulation managed to cause the backed up sewage to drain and
identified that a main sewage line had partially separated.  The problem was however not solved and with
the next rainstorm flooding repeated in the basement as well as through the
kitchen sink, which caused the entire hardwood floor to buckle.  A repeat visit by the same plumber claimed
that this was an entirely new problem! 
Repeated calls to have this and another plumbing services to address the
problem were futile. 
Searching Angie?s list for service providers to replace the
sewer line led us to M & M Construction. 
On line reviews of them were very favorable, but we did not know anyone
for whom they had done any work.  We got
in touch with Anthony (Principal with the company) and he immediately came out to examine the site and provided
us with an estimate and work proposal. 
We took a chance on the fact that reviews of Anthony?s were a reflection
of what to expect.  He promptly began the
work as proposed.  Searches at the MDC for
layouts of the sewage line turned up negative. 
The only record on file was the point at which the house connects to the
city sewage system.  They began work from
the property edge and found a drain line. 
Went through the entire process of replacing the line but when tested
the problem had not been solved!  So
Anthony and his crew after putting a camera down, identified the brake point of
the sewage line and it turned out that the house has two lines that tie into
the a single line under the sidewalk.  So
they re-dug, found the second line and replaced it at no additional cost to
us!  It was a lot of work, and during
this process Anthony kept us fully informed. 
During this ongoing work, our trust in Anthony grew, and
knowing that we needed a new roof, we asked Anthony if he knew anyone who could
redo the roof.  To our surprise, he
collaborates with a roofer on roof work. 
We visited sites where they were replacing a roof and had good opinions
of their work from the homeowner.  We
contracted Anthony to redo the roof!  The
roofers did a very good job and we are very happy with the work.
As we also needed a new driveway due to flooding in the rear
of the house, and knowing that Anthony had the heavy equipment necessary for
excavation work, we engaged him on another project to redo the driveway and
redesign the parking area behind the house. 
Working with him we designed a permeable paver parking area, with
permeable pavers lining the driveway. 
The layout of the pavers and the driveway was completed before the
winter snows and now what is left is touch ups to complete the project and grow
grass in the permeable pavers.  Heavy
rains in the Fall that would normally have resulted in major flooding in the
rear of the house are a thing of the past! 
The snow melts that have recently occurred resulted in no flooding giving
us confidence of a job well done. 
Planting grass where the work was done and other minor touchups still
remain for the spring which we are fully confident will be completed. 
Anthony is trustworthy, a perfectionist in his work, and
very responsive to questions we raised during all aspects of the work he has
done at our home.  I have told Anthony
that he is welcome to bring any client to see the work he has done for us at
any time. 
Thank you Anthony.

FAQs for basement waterproofing projects in Willimantic, CT

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

You can DIY basement waterproofing in some ways to help save on the overall costs. If your basement isn’t experiencing a lot of water but is noticeably humid, you can try running a dehumidifier that will pull the excess water out of the air. If you notice water leaking due to outdoor drainage issues, you can add downspout extensions to keep rainwater away from your home. 

However, if the problem is more severe and requires a more extensive solution, it’s best to call a basement waterproofing professional to assess the treatment you need and install waterproofing safeguards properly. Since keeping water out of your basement is important, ensuring this job is done correctly the first time is best.

Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.

Several factors dictate if you should waterproof the interior or exterior of your basement. Waterproofing the exterior of your home is a great option if you use your basement for storage, as it provides the most protection from water and water damage. If you prefer work done outside of your home versus inside, exterior waterproofing is best for you. However, interior waterproofing is often less expensive since the area is easier to reach and requires less labor.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
