In this Mamaroneck, NY household, there was a relatively small basement but within this small space were many important products installed over time to keep this basement as clean and productive as possible. Although certain aspects of this basement were kept up with, the crawl space had clearly very aged insualtion within it. The homeowner decided to call Connecticut Basement Systems in orrder to have this issue fixed and our employees were more than ready to help fix this issue.

Our team cleaned out their crawl space of the old insulation and any trash or debris that had found its way in there. We then installed new insulation that would never leave that area looking like it once did. A SaniDry dehumidifier was also installed the keep the air clean and filter out any harmful particles. Thanks to our crews great help, the basement once again had insulation that did not look messy and would be much more affective.

When homeowners come to us with a water problem in their basements, we assure them that they are in good hands with the experts in basement water proofing. Due to the excess water in this homeowner’s basement, the space wasn’t being used to its fullest potential.

To fix the issues, Sergio Alves installed a Triplesafe Sump Pump system to keep from a basement flooding by providing three levels of protection that keep your basement dry in all volumes of water. A Clean Space wall vapor barrier was also installed to prevent water vapor from passing through the walls and directs it to the sump pump. Now, the homeowners can use their dry basement to its fullest potential.

Job Stories From Mamaroneck, NY
Waterproofing and Wall Repair in Mamaroneck, NY

This Mamaroneck, NY homeowner was in need of waterproofing her basement after previous water-related issues. With water issues in a basement comes many problems that can arise. Water leaks and flooding can cause property damage, as well as create harmful molds such as asbestos which can create serious health issues for anyone who comes in the home, specifically in the basement. Once we were contacted about the need for waterproofing this homeowner’s basement, we sent out our Sales Representative, Gary Meglino to assess the situation and propose a permanent solution.

One of the more important solutions we installed in this homeowner’s basement was the SuperSump Plus sump pump. With this sump pump, the fear of a plumbing leak or other unforeseen water issues, will dissipate. This pump will keep any unwanted basement water and drain it into the sump system, while also having an alarm that will go off when water levels ever rise too high.

Another solution we provided for this basement was the combination of WaterGuard and Iceguard exterior discharge lines paired with a LawnScape outlet. The usefulness of these solutions is that the WaterGuard discharge line gets attached to the sump pump and any leaks from the basement walls will be collected and flow through the discharge line connected to the outlet. The IceGuard allows water to escape when the discharge line is frozen which will prevent basement flooding in cold weather. These discharge lines connect to the LawnScape outlet which blends in with your lawn while getting rid of any potential damaging items to a basement. With the grated outlet system it also disallows leaves or small animals from getting into the discharge line so no blockages can occur. After the installation of all these high quality solutions, this homeowner’s basement was officially waterproofed.

During the time our crew was working hastily to waterproof this homeowner’s basement, the team noticed structural cracks in some of the basement walls. After bringing this issue to the homeowner, she decided that it was best to install our CarbonArmor system to stabilize the foundation and then to install wall restorations to beautify the walls. 3 walls were given an EverLast wall system which is built into the bottom-half of already damaged walls and uses durable materials that cannot absorb moisture so any future water damage is out of the equation. As for the CarbonArmor system, these are bands of fiber-reinforced polymers which are 10-times stronger than steel, but also flexible enough to contour tightly against basement walls. 7 of these bands were installed onto separate walls in this basement so that these walls are stabilized and will not allow the walls to lean or bow. The homeowner was ecstatic with her now dry, stable basement!

Hello, I've recently purchased this 3-family house in Mamaroneck and it has a basement studio apartment that was finished, but it had some moisture issues and I'd like to seal it up and re-finish it basically. I found evidence of moisture intrusion in the floors, mold & mildew &c., which I assumed was coming up through the foundation. I tore off most of the subfloor myself and sure enough I found cracks in the foundation which I assume were the source of that. I can also see outside that the foundation needs to be sealed up better with some cracks repaired and grading improved, so water does not seep down from the base of the foundation. Ultimately I'd like to see if you could finish the demolition (floor basically), seal up the foundation as needed, and re-finish the unit, mainly floors but perhaps some wall pieces as well. Thanks!
