Above are before and after photos of a recent crack repair using our flexispan crack repair system. We had previously done work for this homeowner, and he recently noticed a crack in his basement wall. The crack was leaking water into his basement and he knew that Leader Basement Systems is who he should call. Our inspector went to the home to take a look at the crack and determined we could use our flexispan system to seal it. Our team went out and filled the crack from top to bottom with our special Flexispan sealent. Flexispan differs from other crack fillers or sealents in two major ways. First, Flexispan eliminates the use of messy expoxy injections and instead seals the crack with a flexible sealent that will stop water seeping through the crack. The other key factor in our Flexispan system is that it doesn't end with sealent. Our system uses an additional step to make sure that no seepage will make it pass the sealent. A second layer of  beveled foam is used, which would drain any small amount of additional seepage down into your drainage system or into a small drywell created under the basement floor.

This valued homeowner knew it was time for us to lift, level and seal this cracked foundation and quick! It has been developing for about 30 years and he was concered about the noticeable sinking. We were too! So we quickly got to work and remedied the situation using our incredible PolyLevel Injection Foam- a polyurethane expandable foam that links and lefts the ground above as it expands below. It is waterproof and guaranteed to lift!

We were on our annual service checkup for this customer in Shrewsbury, MA when our Service Specialist Mike found a large amount of Iron Ochre in sump pump basin. This is a bacteria in the water that will grow on the pump, in the discharge line, in the WaterGuard and all that can be done is a hot water flushing and cleaning.

Sump Pump Installation in Shrewsburry, MA

We received a call from a customer in Shrewsbury regarding her mother's home. The house was being sold, and they were aware of previous water problems. The customer wanted to fix the problem at the earliest time, in order to ensure it was taken care of.

The homeowner decided to have a SuperSump pump installed, and they installed a Lawnscape Well at the end of the discharge line.

Vicinity of Richard Ave in Shrewsbury
Boy, do we have a fun window in the basement.. It acts as vent for the dryer, furnace, sump pump and a few TV 'cable' cables escape here. Crack X did a great job helping with an issue running from a nearby waste pipe to the base of the window frame, however, the window as a whole is the oldest in the house, has a wood frame, and is a clear source of water leaking into the basement. I believe that we need a quote to repair that entire area, including modernizing the window and frame. Being a novice, I can only assume the furnace, sump pump etc will have to be disconnected whilst this happens. Can you help? Thanks!

My basement gets water. I would like to finish it so would like to get an estimate on waterproofing. I am not sure if it simply needs a sump pump, but need a pro to come out and tell me. Thanks so much!
Vicinity of Saybrook Road in Shrewsbury
We recently moved to Shrewsbury. It appears that the sump pump in our basement is an amateur installation. Earlier in the week we had water in our basement with all the rain and what I believe is sump pump not being able to keep up. I would like you to come take a look and give me an estimate to fix and waterproof our basement. Thanks.

Vicinity of Boylston St in Shrewsbury
1946 2 story single family home. Uneven wood floors and floor sag toward the center of the house. Accesible basement.
Vicinity of Westwood Rd in Shrewsbury
After 21 years, one corner of our basement is leaking. We cannot determine the source. We thought it was a clogged gutter, but after repairing that, we believe the water is either coming in through a crack in the foundation or more likely, the floor. We survived the last high rain storm we had only to find water 10 hours after the storm ended. We inherited a French drain on our property which we are wondering has become ineffective. We now believe we've had water coming in for several months (since at least June '17) but we didn't realize it as it's been a subtle leak.
