"Flooding in our basement has been a recurring problem over the years. We’ve had various companies do work for us but they failed to keep our basement dry for longer than a few months at a time and only did a semi okay job. That all changed when we hired Empire Construction Waterproofing. Chris gave me a very reasonable price for the size of our project. They had a team down there starting to work almost right away! They were incredibly professional and worked very efficiently. Once they were done they left the space in great condition. My husband and I were very satisfied with the project. The results went above and beyond our expectations, the quality was unlike anything we’ve ever seen before. It was such a pleasure working with Chris and Empire Construction Waterproofing. I have recommended them to all of my friends and family. If you’re having basement issues definitely give them a call."

"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.

Basement Waterproofing questions, answered by experts

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

If foundation problems are not fixed, they will likely worsen over time, leading to more complex and expensive repairs. Neglecting a damaged foundation can cause a range of issues, including:

  • Structural Damage: Minor problems like small cracks can escalate into major structural issues. This can damage the house above the foundation and, in severe cases, lead to foundation walls caving in or a total collapse.

  • Water Damage and Pests: Moisture and water intrusion can cause flooding, mold growth, and pest infestations.

  • Health and Safety Risks: Mold can lead to poor indoor air quality and other health risks, while structural instability poses a significant safety hazard.

  • Reduced Home Efficiency: A compromised foundation can negatively impact your home's energy efficiency.

To avoid these escalating problems and costs, it's best to hire a foundation repair company to address any issues as soon as you become aware of them. The earlier problems are discovered and fixed, the lower the repair cost will likely be.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.

In most cases, a crawl space will not dry out on its own unless the moisture comes from an uncommon flood and isn’t expected to be a recurring issue. For most homeowners, moisture problems in the crawl space will only continue to get worse over time, so addressing the underlying problem with gutter systems or a foundation drainage system and setting up a preventative solution like a dehumidifier is necessary.
