Do you perform small home renovations or remodels?

There are several factors help determine which projects are well suited for us. First is the project size. If the project is small (e.g., bathroom remodel, kitchen remodel, door or window replacement), we will likely not be able to quote it as cost effectively as a smaller builder or general contractor would.   Second, does the house have lead paint.  Although we are a Certified Lead Renovator and do occasionally take on projects that require lead paint removal, we prefer that the lead paint removal is a very small percentage of the scope of work.  Third is location.  For a smaller project, we prefer to stay within a 25 mile radius of Rochester.

Do you remove lead paint?

At Groen Construction, we take lead poisoning prevention very seriously. Although we are certified by the Environmental Protection Agency (EPA) to perform renovations on projects that disturb lead-based paint, we are not a lead abatement company. Abatement is a specialized activity designed to specifically address and remove lead in the home. We do not perform lead abatement services. 

​What is the average cost of Insulated Concrete Form (ICF) on a new custom built home?

Typically, you can anticipate a 10 - 15% increase in overall cost if you build a home with ICF.  If it is a simple, straight forward house, it will be closer to 10%.  A more complex house would be closer to 15%.  ICF tends to be more cost competitive on commercial projects.  Some commercial projects have even turn out to be more cost effective when built with ICF.

​Where do you provide construction services?

Most of the residential projects that we target are located in Southeast New Hampshire and Southern Maine. We tend to stretch a bit beyond that for commercial projects. We are not licensed to work in Massachusetts.
