Job Stories From Londonderry, NH
Push Piers Installation, Londonderry, NH

Miles C. of Londonderry, New Hampshire was having concerns with his home. He was experiencing sticking doors and windows, cracks in the foundation walls, sloping and sagging floors, and cracked slabs outside. Design Specialist Paul Magowan came to the home and looked over all of the homeowner's concerns and proposed that his home would benefit from Helical Piers and some PolyLevel.

Crew Lead Nick Melo and his team came to the home and dug down to the foundation footing. When they got to the footing they installed Helical Piers in the affected areas. After all the piers were pressed down to their desired PSI, the crew filled the void with PolyLevel. 

Foundation Pier Installation, Londonderry, NH

This homeowner in Londonderry New Hampshire was experiencing their house settling and beginning to sink. With the issues getting worse, the homeowner called Erickson Foundation Solutions and set up a meeting with Design Specialist Paul Magowan. Paul came to the home and looked over the homeowner's concerns. Paul recommended that installing foundation piers would be necessary to stop the home from sinking.

Crew Lead Chris Hanulek and his team came to the home to install the Piers to the foundation. They start by digging near the affected areas to expose the foot of the foundation. Then they create a notch on the foundation where they can attach their bracket that holds the pier. Next, they use a hydraulic press to push the pier down into the ground until it hits a substantial force that the home can rest on. Although it is not guaranteed, it is not uncommon to see a house lift a couple of inches. If the home ends getting some lift, the crew will fill the void with PolyLevel to make sure that the soil doesn't wash away.

Hi, I found you while searching Google for "concrete floor repair near me" from Londonderry. I recently leased a double unit in the Crossroads Mall in Londonderry. I am in the process of ripping up the carpet and found some sections that need leveling repairs because the top half inch of concrete is smashed. I _think_, so far, that the required repairs are fairly minor and will just involve leveling compound, but it's not something I want to do myself. If this is something you do, would you be able to send someone over to take a look and provide a quote for repairs? Or, if the project is too small, would you be able to provide a referral? Regards, --Erika Stokes

Hi Matt, My wife and I just had a home inspection done on a house we're purchasing in Londonderry. The radon was somewhat high (3.2) and we'd like to know what the cost will be to have some mitigation done. The basement is about 75% finished which leaves two rooms (on opposite corners of the basement) unfinished. The house is a 1999 colonial with a walk-out basement in the rear and a 43x26 foorprint. I can send a floor plan of the basement if needed. If you could give me a rough estimate on the price and an idea of how effective at radon reduction that design will be, if would be greatly appreciated. Thanks, Evan
