fieldstone foundation repair costWe’ve been repairing fieldstone foundations and Michigan basements for over 15 years and I thought I would shed some light on the stone foundation repair costs that we typically encounter.  Projects vary widely and so to the costs associated with different projects but I think I can offer a general window of cost to fix an old Michigan basement.

Typically the stone basements we repair are between 400 square foot (approx. 20’x20′) and 600 square foot. Obviously some are larger and some smaller, but this seems to be the general rule. If it is an older foundation, say pre 1920, it is usually closer to the 400 square foot size.  This is for a very pragmatic reason. Back “in the day” the excavation for the Michigan basement was by hand.  So starting in the spring the goal was to dig the hole and get the stone foundation laid before the cold Michigan winter.

Fieldstone Foundation Repair Cost Variables

Here are some of the variables that determine the cost to repair a stone foundation:

  • size of the foundation
  • size of the stones used to build the foundation
  • current condition of the walls
  • current condition of the mortar joints
  • availability of water and electricity on site.
  • accessibility of the basement or crawlspace

When I consider the dozens of stone foundations we have repaired I would say that most of them fall in the range of $3,600 to $5,500 dollar range.  We have done many that cost less, and many that have cost more, but I would say 70% of the stone foundation repairstone foundation wall costs we encounter fall in that range.

Having said that, most of our customers contact us before they have wall collapses and usually most of the stone is in place and intact.  The main issue is usually deteriorated mortar joints or maybe some loose or fallen stones. The projects we’ve completed where walls have collapsed or failed are always much more in terms of cost to repair.

Re-tucking mortar joints in Michigan stone basements and foundations makes up about 70% of our work in any given year. I would say around 8 in 10 of our foundation retucking projects are basements with the rest being stone crawl space foundations of one type or the other. I should note that another term for retucking would be tuck pointing Often times the existing stone basement walls are in tact and basically in place.  Many times there isn’t any bowing in the walls or even any stones actually missing or falling out.  The mortar joints between the stones have simply rotted away and turned back into sand almost. Some of the stone foundation repair projects we do the joints are completely missing and the wall appears to be stacked stones without any type of mortar visible between the stones.

How We Fix Crumbling Stone Basement Walls

I will work on getting some before and after pictures here on the this article so you can see some of the basement wall we encounter that have missing mortar joints of one degree or another. To learn more about the stone foundation repair work we do you can visit the home page of this website.The process of fixing the mortar joints  or (Re-Tucking, Retucking, tuckpointing, tuck point, and repointing are also words I’ve heard used. And to be honest, just pick a word, we know what your talking about) n a stone wall varies based on the existing condition of the wall.  If the joints have mostly disintegrated then we basically just clean the wall, being sure to get back in the joint area.  There is usually a good amount of sand and debris that needs to be removed.

Usually some of the mortar joints are remaining in the wall and have reached the point where they are no longer structurally sound.  We usually remove these soft, loose, or crumbling joints with a masons hammer, chisel, and a brush.  In rare cases we may us a chipping hammer or even waterjet the joints.

  2. Hammer out Old, Loose, Failing Mortar Joints
  3. Clean the Wall and Joint area To Receive New Mortar
  4. Apply Bonding Agent
  5. Tuck point new joints and brush to seal
  6. Coat walls with Water Proofing Cementitious Coating

A good percentage of the old Michigan basements we re-tuck will have some mortar joints that are still structurally sound, some that need removed and retucked and some that are already completely gone and to be re-tucked.

A typical stone basement is around 20’x24′ or so, many are larger as they have been added onto, but typically they aren’t as big as the actual foot print of the house.  Most of the basements we re-tuck take 3-5 days to complete depending on the severity of the existing wall deterioration. We use a sand and cement mix with some type S mortar and a bonding agent.  This mix works well to get back into the wall and is strong enough to hold the stones in place for years to come.

It’s been a great winter so far this year and we’ve been busier than ever over the last few months repairing old Michigan basements which are typically built with stone walls.  We’ve been to Iron Mountain in the Upper Peninsula, Fenton, Grand Blanc, Owosso, and few projects on south west Michigan as well.  Many of the stone basement repair projects we do can be done in the dead of winter.  Unlike barn foundation repairs, which are usually unheated and frozen during the winter, Michigan basements can often times be completely repaired during the winter months.  Sometimes we need to come back in the spring if there are exterior issues to be addressed, but the bulk of the work tends to be on the interior basement walls.

Stone Basement Repair Process

Our process is pretty straight forward, it’s not real complicated, but can be tedious depending on the current condition of your stone foundation walls.  Projects fall in one of three categories or encompass some of all three.  Here are the three categories most projects fall into, they are in need of:

Rebuild-  It’s obviously better to maintain a stone wall to prevent a wall collapse or wall failure.  We come across several barns each year where the walls have actually fallen in.  We’ve rebuilt stone barn walls all over Michigan, some have holes as big as 30′ long and a few had holes this big in several locations.

Repairs- On many of our Michigan basement repair projects most of the stone are in place, some may be loose or may have fallen.  There are areas of missing mortar joints that have rotted or crumbled away and are missing all together.  Some of the joints may be in place and quite solid.

Preservation-  When we find large areas of the stone basement foundation walls to be secure and the mortar joints mainly in tact, we like to preserve these joints so they will continue to last for years to come.  This can be done several ways.  One of the most common things we do is to bond a cement based mix to the existing joints thaMichigan Basement Repair Aftert haven’t been completely redone.

It seems most of our Michigan stone basement projects are missing some joints in a few areas and need the remaining joints to be preserved.  Often times you find a little pile of dust and debris, which is really old lime mortar, along the wall.  This is a tell tale sign that preservation may be a good idea. If your stone basement is in need of attention, consider getting in touch over the winter months. We are typically a little slower during these months and that can mean a better deal for you.
