Installation crew reputation was iron clad and they lived up to it. On time, on budget and done right. Period. We asked for extra business cards because we will be passing them out.

Michael and Nancy R. of Billerica, MA
Customer Testimonial

“
Erickson Foundation Supportworks installed push piers to stabilize and support our house's foundation. Everything was completed, the work area was cleaned up, and the crew foreman did well to explain everything. The crew was great, all very polite and always kept us up to date. The project ran into some unexpected hiccups (no fault of the EFS crew) and we were kept informed along the way.

Customer Testimonial

“
Erickson Foundation Supportworks was easy to work with, everything was explained in detail before work started. The office staff had excellent customer service, and the crew was courteous, hardworking and efficient. We are preparing to put house on market, an old colonial with granite slab and field stone foundation(s) and dirt floor. The PolyLEVEL product was ideal for helping the wall keep stay together and strong.

Before and after photos from jobs I've worked on:

Before

After

The entrance to this small business in Warner, New Hampshire had 50 year old concrete steps. Over time, the steps settled and cracked, and so the store front was not appealing. The owner planned on doing a complete remodel of the exterior of the building, but first needed to address the stability of the steps.

PolyLEVEL was injected beneath the steps to raise them back to a near level position, and the cracks were sealed to complete the look. Job was completed by foreman Andrew Ahlquist.
Before

After

This home in Hampton, NH was built on a slab, which over the years was gradually settling. PolyLEVEL was an ideal solution to lift the slab and fill the voids underneath, while doing minimal damage to the inside (holes drill through the slab). The slab had settled up to an inch, putting the floor out of level, and PolyLEVEL easily lifted it back into a level position.
